Chapter 208 Ore Mining Matters

() According to the records in the report I got, this mineral that is extremely difficult to mine is called demonized crystal, which is an excessively demonized crystal. If analyzed according to the chemical composition, this thing is almost the same as ordinary crystals, but according to the energy detection, it will be found that the internal energy reaction of this thing is extremely high, which can be said to be a very unstable ore.

Although magic crystals are extremely unstable, they are not completely unsaveable, so some magic crystals can occasionally be found on the ground. However, all the magic crystals found on the ground are near volcanoes, whether they are extinct or active volcanoes. Anyway, magic crystals only appear near volcanoes. Generally speaking, this distribution situation means that the magic crystal is actually a substance that exists deep underground, and its appearance near volcanoes is mostly due to the transport of magma to the surface during volcanic eruptions. . .

According to the characteristics of the origin of the demonized crystal, it can be confirmed that the Dark Council should have this kind of ore. After all, the demonized crystal on the ground is brought up by lava belt, while in the underground world, the lava river and lava lake are all a lot of. So it is certain that the Dark Council should have a demonized crystal mine, but I did not expect that the difficulty of mining this thing would be so high.

The magic crystals on the ground are said to be mined, but in fact they are basically picked up. These demonized crystals brought to the surface by lava were solidified in volcanic rocks after the lava cooled. Then as time passed, these volcanic rocks were gradually eroded due to weathering, water erosion, etc., and finally the demonized crystals wrapped in them were will be exposed. These magic crystals were discovered by some lucky people, and then became the magic crystal ore we use. Of course, since everyone now knows that magic crystals are found on the ground in lava belts, some people will deliberately dig in volcanic rock areas. However, because the distribution of magic crystals is uneven and the stock is very low, basically the output has never been It's never been higher. . .

Fortunately, the magic crystal is a special material with a relatively single use, so even if it is not available, it will not affect everyone's normal use. However, it is more unfortunate. Although the use of this magic crystal is relatively simple. But the only uses include: strengthening enchanted equipment, making artifacts, and conversion cores for super-powerful energy weapons.

The above three things are basically dispensable things for ordinary players. For example, some advanced players may need to use it once or twice to enhance the enchanted equipment, but it will definitely not be too much. As for the remaining two uses, they basically have nothing to do with ordinary players, or even Even some medium and large guilds may not be able to use these two purposes. However, the problem is that we are the Frost Rose Alliance, and we are the number one guild in the world. Just because others can't use it doesn't mean we can't use it. What's worse is that we can not only use this thing. Moreover, the consumption is quite large, and the main reason for this large consumption is that the magic crystal can be used to make a device called a magic resonator, and this device is one of the core components of the mobile angel used against the protoss.

The number of mobile angels used by our guild against the gods has been small from the beginning, and the cost is astonishingly high. One of the big expenses is the magic crystal. Because the output of this thing is extremely unstable, the market is out of stock. Therefore, we have to spend a large amount of money to spread out the acquisition network and buy them as soon as they appear, so that we can barely maintain the use of our advanced weapons. It can be said that since our guild started using magic crystals, the quantity of this thing has never been enough.

Because our demand for magic crystals is quite large, and the output of this magic crystal is unstable, we are very happy that the Dark Council can magic crystals. However, what I didn't expect was that we were almost picking up magic crystals on the ground, but it was a completely different situation underground.

According to the information on the mineral origin given by the Dark Council. There are two origins of this magic crystal. One is the lava lake and lava river we guessed before. The magic crystals from this origin are much more difficult to mine than those on the ground. Therefore, all the demonized crystals here are at the bottom of the lava river and lava lake. If you want to mine these demonized crystals, you have to sneak under the lava. In the past, the Dark Council used certain monsters that lived in lava to collect this thing. However, because the distribution of magic crystals in lava is almost the same as that on the ground, although the difficulty of mining in this way is only slightly higher than that on the ground, the yield is still minimal. The only advantage is probably that it is relatively stable. In any case, mining demonized crystals in underground lava is still an extremely dangerous job with low returns.

Although it is quite difficult to mine magic crystals in the lava river, and the yield is not high, this is not the main reason that makes me crazy. The main thing that really drives me crazy is the black hole at the center of the Earth that is the real productive mining area for Demonic Crystals.

The earth's core black hole is not a black hole in the true sense. It is actually just a hollow sphere. The outermost layer of the earth is the crust, which is a solid outer shell made of rock, and below it is the mantle. The mantle is not a solid layer, but a layer of liquefied magma. Because the mantle is made of liquid, theoretically there should be no voids inside it. However, the mantle is not actually void-free. Just like there are bubbles in water, there are also such bubbles in the earth's mantle, but its outer shell is not a water film but a layer of dense crystalline silicon. This layer of crystalline silicon itself has no value, but its interior has absorbed a large amount of geothermal energy due to its depth underground, and formed a large number of magical crystals under ultra-high temperature and ultra-high pressure. Protected by this crystalline silicon shell, the interior is almost entirely made of various types of crystals, with a hollow sphere in the center, which is the earth's core black hole. Because the temperature of the lava in the mantle is very high, it emits light. However, the black hole in the center of the earth is just crystalline silicon. Its heat is much lower than that of the lava, so compared with the surrounding lava, it looks like a black hole. The black hole in the center of the earth is like a black hole. That's why it got its name.

In any case, it is definitely true that the black hole in the center of the earth contains a large number of demonized crystals. The shell of a black hole in the center of the earth is generally only more than a hundred meters thick. As long as this shell is penetrated, the interior is a mixed mineral layer composed of various crystals that is nearly 30 meters thick. The inside of this mineral layer is filled with crystals and rare metals that exist in a simple state. It can be said that it is basically money. Considering that the diameters of these earth-centered black holes are basically more than three kilometers, if one can be successfully captured, it will be a huge income even for our guild. And as long as we can capture three or five geocentric black holes, it will be considered a big success even by our standards.

With such huge profits, who wouldn’t be tempted? However, it is because of my heartbeat that I am going crazy.

The game "Zero" only allows players to increase the map area that they can enter. Therefore, the influence of pressure in seawater on living organisms is deliberately weakened. Moreover, most of the equipment in the game has super pressure resistance, among which the knight's helmet also has the function of a deep-sea respirator. These are all map games that allow players to enter underwater. However, although the game weakens the pressure effect in seawater, it does not change other effects of pressure. For example, the various effects of air pressure on the human body remain unchanged.

Unfortunately, the pressure in the mantle, like the air pressure, also belongs to the unmodified part. That is, within the game. The pressure in the mantle will be close to the real data in reality.

According to the mineral mining assessment report given by the Dark Council, geocentric black holes with magic crystals generally reside in the shallow mantle layer. The pressure in this area is approximately: 1 gpa (pa is the unit of pressure, Pascal, and g is the capacity of the computer hard drive. That unit is g, but it is not carried by 1024, but carried by 1000. In other words, 1 gpa is equal to 1 billion pa).

1 What is the concept of gpa? The air pressure around us when we are on the ground can be roughly calculated as 100,000 Pascals. The pressure underwater can also be roughly calculated as 100 meters of water depth corresponds to 10 atmospheres, which is 1 million Pascals. According to this calculation, the water pressure on the seabed at a depth of 10,000 meters is only 10 gpa, and a pressure of 1 gpa is equivalent to the water pressure at a depth of 120,000 meters. Of course, there is no such deep ocean at all on earth.

In reality, the deepest water on earth is at the bottom of the Mariana Trench. The depth here is only a little over 11,000 meters, but even at this depth. There are only so many submarines that can go down. They are all dedicated deep-sea exploration submarines. Conventional military submarines have problems reaching a depth of even one thousand meters, and the maximum safe depth is only five to six hundred meters. That is to say. If the effect of water pressure on living organisms is not reduced in the game, the depth of seawater we can move in the game may only be within a hundred meters. But now, we can easily run to the seabed thousands of meters deep in the game. Of course, most players still can't get down to places like the Mariana Trench. It's not a problem of water pressure, but a problem of monsters. According to the settings in the game, monsters in seawater double in size for every 100 meters they descend. Therefore, the depth of the Mariana Trench is basically a sea monster paradise. Players go down there just to give away food.

If the game does not reduce the effect of water pressure, a depth of one hundred meters will be the player's diving limit, and the pressure within the mantle is completely unmodified. To obtain the earth's core black hole, you need to go down into the mantle with a pressure of 1 gpa. This pressure is equivalent to a pressure of 10,000 kilograms per square centimeter. How much space does one square centimeter take? The palm of a two or three-year-old child's hand is more than one square centimeter when spread out. Applying 10,000 kilograms of pressure on such a small area, this pressure has exceeded the power of any weapon in the world. In other words, if you can withstand this kind of pressure, even if you are directly hit by a nuclear weapon, you will be able to survive without taking into account the high temperature and nuclear radiation.

How about it? Isn’t this kind of defense awesome?

In fact, the trouble goes beyond that. In addition to the pressure of 10,000 kilograms per square centimeter, another trouble is the average high temperature of 3,000+.

Don't think that the magma that spews out of the ground is very hot. Compared with the magma in the mantle, the magma that flows to the ground has actually cooled down. Therefore, the temperature in the mantle is definitely a huge problem. My armor can indeed withstand the high temperature of more than 3,000 degrees, but the problem is that the mining equipment is not my armor. You must know that my Dragon Soul suit is top-notch even among artifacts. Do we need to build a set of artifact-level mining machines to mine? This investment cost is probably greater than the value of the ore. Besides, it is unknown whether the system settings allow mining machines to be turned into artifacts. After all, I have never heard of anyone enchanting mining equipment before, which means that there was not even mining equipment at the attribute equipment level before this.

Although ultra-high temperature and ultra-high pressure are troublesome, they are still dead things, and there is always a way to overcome them with a little effort. But there are still some problems that cannot be solved.

First of all, the mantle is not a fixed mass. It is a viscous liquid that flows. This creates a positioning problem. Earth's core black holes are not located at the interface between the Earth's crust and the ground. They are actually located a little above the middle layer of the Earth's mantle. Looking at the cross-section of the earth, this place is actually quite close to the earth's crust, but that is a cross-section of the earth. In fact, this place is very far away from the earth's crust. Being able to stay in the Earth's mantle is already a big problem for us. It also requires positioning, which is simply a life-threatening matter. Even on the sea, you can still rely on the sun and stars for positioning, but in the mantle, the surroundings are opaque magma, and the visibility is basically zero, although it is not completely dark. But it is still invisible. Although the lava can shine, it is not transparent. This is definitely a very annoying problem. Of course, using teleportation to return to the ground is also a good method, but there is still a slight problem. That's... how do you take out a scroll and unroll it in lava? Anyway, the teleportation scrolls I know so far are all made of wood and monster skins, and can be burned by lighting a fire. There is no need to think about the foundation in the beast, it will turn into ashes if touched.

Even if the positioning problem is solved, there is still a problem of detection. Earth's core black holes are not everywhere in the earth's mantle. Although there are a lot of them, it is not that easy to find them. These black holes drift around in the Earth's mantle like bubbles in water, so their locations are uncertain and finding them is very difficult.

Even if we solve the problems of high temperature and pressure, return and search. There is also a fifth issue to carry.

A black hole in the center of the Earth is a hollow sphere more than three kilometers long. Its shell is extremely strong and ensures that the magic crystals and other minerals wrapped inside will not be lost. We can't crack it in the ground yet. Once their pressure-resistant structure is destroyed, these things collapse and the minerals inside dissolve quickly in the lava, leaving us with nothing. But we won't have any kind of space gear to fit it in without destroying the shell. Even though the Phoenix Dragon Space has such a large volume, the entrance is not that big, and it is really impossible to stuff such a huge thing inside. Then, if it cannot be stuffed into the space equipment, it can only be dragged as a whole. It goes without saying that everyone knows how difficult it is to drag a sphere with a diameter of more than three kilometers in magma, but it doesn't sound like something human beings would do anyway.

None of the above five questions sounds like an impossible task, but that’s not all.

There is a saying that wherever there are people, there are rivers and lakes. The game system obviously uses this sentence flexibly. The system's setting for players is: wherever there are players, there are monsters. No matter how inhospitable the place is, no matter how restricted the life is, or the biological desert, it cannot stop the monsters. As long as the player can reach the place, the monster must have a way to settle there. Just like the Mariana Trench, which players rarely go down to, not only is it not a restricted area for life, but it is a monster paradise.

Considering that we have seen monsters living in lava many times, it is basically certain that there are monsters in the mantle. Moreover, according to the consistent rules of the system, the harder the area is for players to reach, the more powerful the monster will be.

In fact, this setting is also normal. Areas that are difficult for players to reach indicate that the environment here is harsh, and those who can reach such places must be advanced players. In an area that only advanced players can reach, you put a bunch of fish monsters there. What will the players who have gone through all the trouble to get there think? Therefore, in order to implement the system's purpose of tailor-made monsters for each player, any special area that can only be reached by advanced players will inevitably have powerful monsters that only advanced players can handle. Of course, there are many monsters that can defeat advanced players in turn.

Based on the above situation, if you want to mine the earth's core black hole, you must withstand a pressure of 10,000 kilograms per square centimeter, in a lava of more than 3,000 degrees, with god-like luck, encounter an earth's core black hole, and then drag this A huge object of more than three kilometers swims up tens or hundreds of kilometers in the middle of the earth's mantle and returns to the dividing point between the crust and the mantle. Finally, it has to seal the entry channel, then break the thing into pieces and sort out the useful ores. Only when it is loaded into the Fenglong space can the task be completed. Of course, during this whole process, you have to face super monsters that may appear at any time. Not only do you not get killed by the monsters, but you also have to be careful not to let the monsters destroy the black hole in the center of the earth, otherwise everything you have done before will be in vain.

I almost went crazy after reading this series of requests. In such an environment, let alone machinery and equipment. It seems like Kristina is the only one in our guild who can hang out. Moreover, we are limited to just going down there. As for how to find and bring back the black hole in the center of the earth, it seems that we cannot do this.

"President." Watch me finish reading the report. The player in charge of machine design said: "We really can't produce such equipment! The environmental requirements are too harsh. Minerals must be mined directly in the mantle. This requirement is simply unacceptable!"

I thought for a while and said: "You design other equipment first. I'll find someone to take a look at this thing. If it doesn't work, you don't need to make it. At worst, we only need the ones in the lava river, as little as possible. It's better than It’s not strong!”

"In this case, let's design other equipment first."

After sending away the person in charge, I took this thing to find Woma. As the technical director of the guild. Woma certainly knows a lot. If she can't come up with a solution, then we can basically say goodbye to these minerals.

With the help of the communicator, I quickly found Woma who was supervising the display of the super airship in the steel city.

"Hey. President, why are you here? Want to see the construction progress of the aircraft carrier?"

"No, I am encountering some technical difficulties and need your help to find a solution."

"What kind of problem? Let me take a look first and then talk about it." Woma is engaged in research. Of course, rigorousness is the main quality. She will never make random promises without knowing the situation.

I directly took out the mining requirements for the black hole in the center of the earth, and also analyzed the major problems mentioned before.

Woma and I were almost the same at the beginning, and they frowned at this information. "This earth's core black hole is of great value, but is it too difficult to mine?" Woma said while handing the information back to me: "Mining the earth's core black hole in the mantle is almost equivalent to making a planet. Drilling. Thanks to this game, in reality this is basically a technology at the level of large-scale development of the universe. You know, in reality, we have not been able to even launch a detector into the mantle. But you To go in and mine such a large mineral. It’s a dream!”

"Is it really not possible?" I asked a little disappointed.

Woma shook his head, which made me feel very disappointed. But she didn't expect that what came out of her mouth was: "It's not completely impossible, but it's definitely not possible to mine purely by machine."

"Oh? Please tell me what the specific situation is?"

"I can't tell you clearly here, so come with me."

Under the leadership of Woma, I went directly to Cambridge on this aircraft carrier. There was actually a set of magic projectors that were exactly the same as the conference hall in Essinger. You must know that this three-dimensional imaging technology is very troublesome even if it is based on magic, otherwise we would not only set it up in Essinger. I didn’t expect it to be installed on this ship. But considering that this thing is so big, it will definitely be the flagship of the fleet in the future. Installing such a three-dimensional display system will indeed help the commander's command decision-making. After all, this is an airship, and the battle must be three-dimensional. The plan map marked with a chart is obviously not very suitable for the command needs of this kind of warship.

After entering Cambridge, Woma asked the workers who saluted us to continue their work, then turned on the imager and asked the military god to connect the imager.

The main reason why this kind of imager is not popular is that it is very troublesome to operate. Players rarely use it, and it is also a big problem to master it flexibly, so few people use it. But because our guild has such a heaven-defying existence as the God of War, this is not a problem for us.

After the military god said the connection was completed, Woma immediately said: "Give me a three-dimensional model to build."

"clear."

After the War God confirmed, Woma began to reach out and pinch a light spot displayed in the air, and then pulled both hands to both sides. The false light spot formed by the projection was immediately pulled away and turned into a straight line, and then Woma I quickly pinched it here and pulled it there, and soon I made a columnar object with a hexagonal bottom. During this period, War God always makes those virtual parts change following Woma's gestures, as if Woma is holding a real object.

This kind of 3D modeling assistance system has actually existed for a long time, but this is the first time I have seen it in a game.

The shape of the columnar body made by Woma is quite beautiful. Although its base is hexagonal, it is not a regular hexagon. This base looks more like a triangle, because it has three non-connected sides that are very long, and the other three non-connected sides are only one-tenth of the length of the three long sides. Therefore, if you don’t pay attention, this columnar body will feel very long. It looks like a triangular prism, but in fact it is a hexagonal prism.

After completing the object, Woma began to demonstrate it to me. She first pointed at this thing and said: "This is the mining machine you want. Of course, this is a miniature image. The real thing should be much larger than this. The diameter of the circular surface on the bottom may be about five meters, and the length should be close to twenty meters."

"But how do you mine something like this?"

Woma directly pulled the front end of the thing, and a gate opened automatically. At the same time, Woma introduced: "There is an openable door at the front of this mining equipment, and there is an ultra-high frequency oscillator hidden in the door. .The external structure of the equipment body is close to the triangle, which is helpful to increase the structural strength. The surface of these shells is not flat, but slightly arched outward. This can form an absolute pressure-resistant structure to keep it stable under pressure. Of course, stability It's not enough. To deal with pressure, in addition to stability, we also need to be strong. My idea is to use magic technology. The outside of the device will be covered with fire element absorption arrays to use the high-temperature energy of more than 3,000 degrees in the mantle to form a stable support. Force field. This force field will support the entire device against pressure."

"Is it possible?"

Woma raised his head and shouted: "Military God, do some energy conversion."

The military god responded immediately: "The energy generated by the high temperature of 3,000 degrees can be converted to support the pressure of 1 g Pascal, but the energy flow of the conversion device will be very huge. We need a very efficient energy conversion device. General equipment will not be able to To resist this kind of high temperature. At the same time, because it is deep in the mantle, heat cannot be dissipated, which puts very stringent requirements on the equipment itself."

Woma nodded and said: "I have already thought about this. Use thermal energy conversion to form a support field. Then use the internally stored magic crystal and the energy converted from excess heat as a power source to perform internal cooling operations. But this A small water element circulation system is also needed. Water elements cannot be absorbed in the mantle, so the water elements lost during use must be absorbed back. Otherwise, the energy cycle cannot be completed. Our guild has special element energy separation equipment, slightly modified The water element constraint array can be formed in one go, and then the internal equipment can be cooled stably."

"But this only solves the problem of the existence of the equipment. How to mine the black hole in the center of the earth? You don't want to use an oscillator to crush the black hole in the center of the earth, right? There are more than three thousand degrees there. Your oscillator It can only last for three to five seconds at most before it melts, and the black hole in the center of the earth will completely burst after being crushed, and the ore inside will quickly dissolve into the lava. How will we collect it then?"

Woma said calmly: "Pay attention to the gate I just opened. This gate will only open after the front end of the device withstands the black hole in the center of the earth, and then the high-frequency oscillator will start. But this oscillator uses It is a special structure and will not completely shatter the earth's core black hole. According to the data, the shell of the earth's core black hole is crystal, so the oscillator's destructive effect on it is very obvious. Although our oscillator will dissolve in only three to five seconds, but as long as It can penetrate the shell of the earth's core black hole in one second. Note that it only penetrates, not breaks. According to the principle of pressure balance in the earth's mantle, even if the earth's core black hole is hollow inside, it cannot have the same pressure as the ground. So I It is judged that the pressure inside it should be consistent with the average pressure in the mantle, so that it can exist stably in the mantle."

"But so what?"

"How? Don't you understand this?" Woma asked me.

I was just stunned for a moment, and then suddenly it dawned on me. "Are you going to use vacuum pressure to suck out everything in front of you?"

"That's right." Woma said excitedly: "After the shock wave emitted by the oscillator penetrates the shell, it will lose the power to penetrate the opposite shell again due to the change in frequency. However, the shock wave will not disappear, but will remain inside the black hole in the center of the earth. It is reflected many times until the energy is exhausted. This reflection process will produce resonance, which is enough to destroy the fragile crystal structure. Because the minerals inside the earth's core black hole and the magic crystal we need are not the same as the outer shell Material, so the adhesion must be a weak point, and the break must occur at these connection points. After that, the useful ores inside will be completely separated from the outer shell. At this time, there is only one atmospheric pressure inside our equipment, while the pressure inside the earth's core black hole is Up to 1 g Pascal. At this time, the black hole in the center of the earth will eject all the air inside it and the ore that has separated from the outer wall like a volcanic eruption, and then be sucked into our equipment. Although this eruption method cannot be completely Absorb all the ores, but at least more than 80% of the ores can be sucked out. The remaining parts will disintegrate and be completely melted in the mantle due to the loss of pressure in the shell."

I nodded and said, "It sounds like a lot of problems have been solved. But the diameter of each black hole in the center of the earth is more than three kilometers, and the thing you designed is only so big, which may be quite big for us. But For that black hole in the center of the earth, I guess it won’t even be able to contain all the ore in the black hole in the center of the earth, and it will be filled up, right?”

"No, no, no. You got the situation wrong." Woma explained: "We just need a device that can withstand pressure, and then you can let your Fenglong open a space entrance inside the device, and the ore will enter Once inside the device, all will enter your Phoenix Dragon Space. At the same time, when the device is closed, the gas in the Phoenix Dragon Space will return the increased pressure in the device to normal air pressure, and at the same time, you can allow your Phoenix Dragon to arrive Go to the front of the equipment to repair the dissolved oscillator. Although the oscillator is also successful, it is too cheap compared to the value of these ores. Use this method. Before your oscillator is used up, you can Limit the mining of the earth's core black hole. Moreover, when you are ready to return, you can let Fenglong open the space channel outside the equipment. The pressure in the mantle will naturally push the equipment into Fenglong space. As long as you pay attention to the closing time, you can avoid lava. A matter of entry.”

I nodded and said: "This solves most of our problems, but it seems that there are still some small problems that cannot be solved. First of all, when the equipment goes down, it seems that only people like me and Kristina who can withstand the environment in the mantle can Take the equipment with you. And the problem of monsters has not been solved. Oh, the problem of finding these black holes in the center of the earth and returning is still not solved. Although the equipment can be stuffed into the Phoenix Dragon space. But how are we going to come back?"

"As for what you said, only you and Kristina can go down. I think there is no way to solve this problem. After all, the equipment always needs people to operate it, so even if you two are not needed, at least it needs to be able to withstand it. Only people with high temperature and high pressure can go down. Fortunately, the black holes in the center of the earth are mining minerals one by one. You can go down and find three or five in one breath. After collecting, you won’t have to go down for a long time. As for looking for the black holes in the center of the earth, To solve the problem, I think we can try to install a sonar detector on the equipment. The interior of the earth's core black hole is empty, and the outer shell is crystal. The echo signal must be very special. Although the density of the mantle is too high, such a detection distance will not It’s too far, but I think it can at least greatly increase your detection range. There’s also the issue of return. I think this is the simplest.”

"Simple?"

"Yes. You just need to leave a magic pet on it and then follow the telepathy back."

"Oh, I forgot about this!"

After seeing that I passed this point of view, Woma continued: "There is also the issue of monsters. I really have no choice about this. You can only fight the monsters below. I can make you a device that can be used in the mantle. Mining equipment is already at its limit. We are currently unable to make any combat equipment work in the mantle. Also, I suggest you use melee combat if you encounter monsters."

"What?"

"It's very simple. The mantle is liquid, and the crust is not a complete whole. The entire earth's crust floats on the mantle, just like a ship on the water. Think about it if you row a small boat on the sea, and then If two whales fight under the boat, what will happen to your boat?”

When I heard this, I immediately realized that if I used large-scale skills in the mantle of the earth, every move might cause a large-scale earthquake, or even plate changes or land subsidence. After all, the mantle itself is flowing, and any interference we make may be amplified or covered. It's fine if it's covered, but if it's enlarged, the result will be difficult to calculate.

"Okay, this problem is solved. Just inform the designer of what I just said. If you don't understand, just ask him to ask me directly through the God of War."

I nodded and said goodbye to Woma. I returned to the research institute and informed the person in charge of the design and manufacturing of mechanical equipment. After the other party fully understood Woma's design ideas, I asked: "How long will it take to build this thing?" Finish?"

"Now that the drawings are out, manufacturing is very fast. It only takes half a day. But President, you gave us an order for so many equipment at once. Which one should we build first?"

"Just get this one designed by Woma first, and the rest is up to you. You can produce them in order from high to low ore value."

"Okay, then I'll have a score."

After leaving the Machine Research Institute, I quickly returned to the Dark Council. Of course I didn't come in on my own. In fact, I can't get in either. It's just that the Dark Council wants to cooperate with us, so it has now started to set up dedicated personnel at the entrance.

"President Ziri, are you back so soon?" The Sith Speaker didn't expect me to be so fast.

I nodded and took out the list of previous mining equipment, then handed it over and said: "These equipments already have a rough design idea. Among them, we have also thought of a way to mine the most difficult black hole in the center of the earth. The equipment only takes half a day. Finish."

"What? Can you really mine the black hole in the center of the earth?" The Sith Speaker wrote this before just to make the information as comprehensive as possible. He did not really mean that we would go down to the mantle to mine the black hole in the center of the earth. In fact, the only two times the Dark Council mined black holes in the center of the earth were because a black hole in the center of the earth happened to float to the dividing line between the mantle and the crust. And there happened to be an underground race that could live in lava, and then the Dark Council obtained these two geocentric black holes. In fact, they did not have the ability to go down to the mantle to mine the geocentric black holes.

I can also understand the Sith Speaker's surprise. You must know that I was scared to death when I saw this mining condition. But I didn’t expect Woma to have a solution, which was an unexpected surprise.

"Although we have designed the equipment to mine this kind of black hole in the center of the earth, and it can be completed in just half a day. But there is something I still need to explain to you." I said seriously.

The Sith Speaker asked in confusion: "What's going on?"

"It's that damn equipment that requires the cooperation of a guardian creature called a phoenix dragon in our guild to be effective, so the mining process requires our people to be present."

"Eh? Don't you plan to send someone down?" the Sith Speaker asked me in surprise.

I was confused by the question. "Um... from what you're saying, it turns out you expected us to go mining?"

The Sith Speaker nodded and said: "Of course. The temperature in the earth's mantle is as high as more than 3,000 degrees. Do you think we can get down there?"

"Eh... It seems that I was wrong. Since you are here to ask us to go down, that's no problem. But since this black hole in the center of the earth is our equipment and we have to go down to mine it ourselves, then I can't follow your instructions. If I come to buy minerals, I can only give you a little mining fee at most."

The Sith Chancellor didn't pay much attention to this. Instead, he nodded and said: "That's easy to say. Anyway, we have no contribution. If you dig it out yourself, of course it belongs to you."

Speaker Incis did not care about this matter. So our subsequent detailed negotiations went very smoothly. After roughly agreeing on the purchase price of some ores and other things, someone happened to come over and report to the Sith Speaker that the dark elves had been contacted.

Now that the Black Elves have been contacted, I have temporarily ended the discussion with the Sith Speaker. Anyway, this matter cannot be started yet. After all, the equipment has not been built yet, so there is no rush, but the Elves Things over there must be done quickly. This back and forth has already taken a lot of time, so don't let the two tribes start another fight.

The Sith Speaker also knew that this matter was urgent, so he did not waste our time and directly sent Susis, who was rescued by us before and brought us here, back to guide us to the Black Elves. .

In fact, I had known for a long time that the Sith Speaker would definitely send Susis as the liaison officer. We followed her when we came here, so the Sith Speaker felt that Susis was relatively familiar with us and would facilitate communication. On the other hand, and the most important point is that Susis is a dark elf. This time he is going to the capital of the dark elf. It is obviously more suitable to have a dark elf as a guide than other races. Besides, Susis has an unusual status among the dark elves, so it is best to have her guide us.

When we saw Susis again, she was a little different from before. I don’t know if it was the Sith Speaker or what they said to her. In short, Susis was obviously more enthusiastic this time than before, although she was still more reserved due to her personality. , but after all, it is already expressing clear goodwill to us. I estimate that this 80% score is due to the Sith Speaker. We are now cooperating with the Dark Council. This matter should not be a secret within the Dark Council, so Susis's judgment of us has changed from hostile strangers to allies. This attitude is naturally different.

Thanks to Susis' change in attitude, our operation went quite smoothly this time. There were three of us when we came to the Dark Council before, but now besides Susis, only me and Kristina are left here. Persephone was not with us when we returned to Isengard, but had already taken the seeds of the Tree of Life to our temporary base in South America to start preparing to plant the Tree of Life. After all, Persephone is the goddess of Chun, and with her previous performance in the core of the Tree of Life, of course she cannot be missing from the growth of our own Tree of Life. Besides, the reason why I brought Persephone with me before was because her breath of life had an affinity bonus to the white elves, but this was of no use to the black elves.

Although there is no sense of hostility between them, the black elves and the white elves are not the same after all. The black elves worship the power of darkness more than the power of life, so bringing Persephone is completely useless.

Under the guidance of Susis, we quickly turned from a narrow tunnel into a huge underground cave, and not far in front of us was a huge city wall.

Kristina looked at Susis in confusion and asked: "Why does your black elf city have a city wall? This is not the surface world? Wouldn't it be easier to build a city wall than to block the entrance?" (To be continued. )
