Chapter 119 Complex Defense Wall

In fact, the sword array of gold coins is, to put it bluntly, a water turbine. The rotation of the jagged blade wheel composed of flying swords generates centrifugal force and pumps the water in the center of the sword array out of the sword array. During this process, a vacuum pressure will be generated in the center of the sword array, forcing the external water flow to be forcibly sucked into the opening of the sword array, thus forming a vortex of water to suck everything outside into the sword array.

Although those strange fish move very fast in the water, as the sword array is activated at full power, the speed of the water flow also begins to increase rapidly. We feel better behind the sword array, but the front of the sword array has completely turned into a The huge black hole, the sea water in front of it is pouring into the sword array crazily, and the fish schools are driven by the water flow to gather towards the center of the sword array. Although they can feel the danger here and desperately resist this suction, it is a pity. Unfortunately, their resistance was too small and they were unable to resist the strong suction, and they were inevitably sucked into the sword formation.

The water flow in the sword array will be accelerated by the rotating sword array and rotate inside the shock absorber, and the centrifugal force generated will force all the water flow to leave the center point of the sword array and be thrown out to the surroundings. Before leaving the sword array, These water flows must pass through the outer wall of the sword array composed of flying swords, and this is actually a sword wall composed of densely packed sword blades. Of course, the water can pass through easily, but those fish cannot. The fish caught in the center of the sword array will soon be thrown to the outer wall of the sword array along with the water flow, and then they will inevitably come into contact with those flying swords, and then be churned into pulp by countless whirling sword blades. Only then can he pass through the gap in the sword formation.

When this sword array was first completed, we thought it was quite spectacular. But after those fish were really stirred in, we realized that this thing should not be called spectacular, but should be called disgusting. After the fish were smashed, they turned into a large dark red mixture of blood and water, and then these things were pushed backwards with the current, that is, they were all blown to our side, but we couldn't hide yet. Since it was not safe in any other direction, we could only let these disgusting debris baptize us all.

Fortunately, because we are underwater, we all isolate ourselves from the outside world. Those wearing armor had their masks closed, while those without armor had their protective shields activated. No one is actually in the water anyway. So although it feels a little disgusting, there is nothing unacceptable. As long as you don't think about it, it actually feels okay. After all, you can neither smell nor feel the touch here. So you don't have to worry about this at all.

After smashing those strange fish, Jin Coin did not immediately close his sword array. Instead, we maintained it for a while longer, allowing the clear water to wash away all the pollutants around us before closing the sword array. Those flying swords automatically dispersed in the air, and then flew back to the sword pouches of gold coins.

Put away the sword pouch. Jin Coin turned to us and said, "It's done, let's move on?"

"I didn't expect you to have something else." Zhenhong patted Jin Coin's shoulder and said.

"Are you kidding me? Do I have something to do?" Jin Coin retorted deliberately and jokingly: "Whenever something happens, we will go to the training ground to compete. The loser will set up a table and order whatever you want. How about it? Do you dare? ?”

Zhenhong smiled and said: "I'm not like you, who has a rich husband. I make a living by doing things, and I don't have as much spare money as you."

"Excuse, just don't dare if you don't dare."

"Who says I don't dare? Well, let's take a gamble."

"You said this yourself, please bear witness." Jin Coin pointed around and said.

Bingbing smiled and said: "Then can we notaries join in and get some credit?"

"That's a given." Jin Coin said with a smile.

"The atmosphere here is still really harmonious!" Song Zhenghe suddenly interjected.

Christina smiled and said: "A good friend of the guild, why are you so serious? Oh, by the way, don't you have such a relationship with the New Black Dragon Guild? Don't tell me that you are acting like the army all day long! "

Matsumasa stopped talking when he heard this, and Ichiro Tsunoda next to him also fell silent for a moment. Although Inri's place didn't really look like a big military camp, it had to be said that sometimes it was really like that. A bit like that.

Next, during our chatting and spanking, everyone easily approached the bottom of the island in the middle of the lake. Without the interference of those strange fish, we can say that we got here without any hindrance. All you need to do next is find the entrance and sneak in. There should be several entrances and exits to the underwater part of this Banshee House, because although this body of water is a lake, it is not completely closed. If the surface ice can be broken, ships in this lake can actually sail directly into the Arctic Ocean. Moreover, even if de-icing work is not carried out, there are several underground waterways in this place connected to the ocean elsewhere, so it is actually very easy for a submarine to enter and exit the lake.

Since this lake can connect to the sea and allow submarines to use it without hindrance, the Banshee House will naturally not waste such conditions, so they have set up a quite large submarine base here, and the entrance is underwater.

The last time I came here, I didn't go to the submarine base, but I also saw this place, so this time I took everyone here directly. What surprised me was that we actually discovered it directly here. A small entrance and exit specifically for personnel use. However, compared with the underwater facilities of our guild, the entrance to the Banshee House is much older.

Because our guild has the technology of Atlantis, we have waterproof barrier technology. With the existence of this thing, our underwater entrances can be made into very simple straight-through structures, so that the waterproof barrier can effectively separate pure water. For people who need to go in and out, just go through. But the Russians obviously do not have similar technology, so they cannot use such waterproof doors and can only use the most direct watertight room to block entrances and exits. When someone needs to enter the base from the outside, they need to close the inner waterproof door first, and then wait for the person to enter the sealed cabin before closing the external hatch. Then high-pressure gas is used to drain the water to press the seawater in the cabin back to the waters outside the cabin. Then the connection between the cabin and the external waters is completely closed and the inner gate is opened, so that people can enter the base. Of course, you just need to do the reverse operation when it comes out. Although this method is relatively simple to control, it takes up to two minutes to drain or fill water once in and out, so this thing is actually quite slow. In comparison, our waterproof doors are much more convenient.

Although we saw such a gate, we could not use such a device to enter this time because the movement would be relatively loud when it is activated. Even if the other party does not have dedicated personnel to guard the place, our entry and exit may still expose our Condition. Besides, the security of this kind of entrance and exit requires someone to operate it from outside. So if I say that no one is watching this thing, I won’t believe it.

Can't go through the main entrance. We can only consider some other crooked ways. Fortunately, I had a lot of equipment at hand. First, I fixed a waterproof door on a nearby rock, and then dug a hole backward from the center of the door into the rock formation below the island in the middle of the lake. Because the outside of the dug hole is a waterproof energy barrier, there will be no outside water pouring in when the tunnel is dug. This will ensure that the channel will not be filled with water. Although we can also move forward in a channel filled with water. But the problem is that our goal is to enter the Banshee House. And if we don't ensure that there is a water-free environment in the passage, then once we open up the opponent's underground city, the water from the outside will quickly pour into the opponent's city. When the time comes, do you think people will not know that we are coming? Because of this situation, it is necessary to ensure dryness in the channel.

After successfully entering the dry environment from the water environment, we began to maintain absolute silence and carefully followed the pioneers toward the underground city. This process only took a few minutes. The Pioneers approached the outer area of ​​the underground city very quickly. The reason why they knew they had arrived was because the Pioneers hit a steel plate during the excavation process. The opponent's city actually added all-steel armor outside. This is quite strange. Normally, metal products are easily corroded when used underground, so even if there are armor plates, they are rarely used for underground buildings. facade. Even if metal armor is really used as the exterior wall, the underground building will usually have a layer of concrete-like material on the outside to act as the first layer of isolation. After that, it will inevitably need to be equipped with a lime waterproof layer, and then another layer. There needs to be a layer of stone or something, and then metal armor can be considered.

However, the design of the Banshee House in front of them is so strange that they actually put the steel plate directly on the outermost layer.

"Why are the steel plates buried here?" Ichiro Tsunoda asked doubtfully as he looked at the complete steel plate on the section that had been opened in front of him. At the same time, he stretched out his finger to tap on the steel plate to see, but his My hand was pinched before it fell down.

"What are you going to do?"

Ichiro Tsunoda looked at me with a complicated expression, then returned to normal, and then said: "Of course, let's take a look and see how thick this thing is."

"You can't touch this thing."

"What?" Ichiro Tsunoda obviously didn't understand the reason why I said he couldn't touch it.

Next to him, Song Zhenghe came up and pressed his hand gently on the steel plate, and then whispered: "The real function of this thing is not defense, but early warning."

"Early warning?" Ichiro Tsunoda obviously didn't understand why there was such a strange function.

Matsumasa then explained: "These steel plates are equivalent to the collection end of the stethoscope that the doctor puts on you. The steel plate body is similar to a vibrating diaphragm. There is no other defensive material behind this steel plate. If my guess is correct, This layer of steel plate should be hollow afterwards. There are probably many support pillars behind the steel plate, and the echo is deliberately left to amplify the vibration, so that they only need to arrange some sound collectors in these places to know whether the outer armor has been invaded. Once we break through this steel plate, we will definitely make some noise, and this is equivalent to ringing the alarm bell for the enemy."

"Wouldn't this mean we can't move at all?" Ichiro Tsunoda said: "As long as we destroy the steel plate, we will make some noise, and won't we be exposed by then?"

"No, no, no, we don't need to be so careful. What we have to do is not to make any noise. It's not that we can't touch this steel plate at all."

Ichiro Tsunoda is not an idiot either. After thinking about it for a moment, he realized it, and then asked in a low voice: "Then which one of you has a way to open this layer of things silently?"

"It's up to me to do this." Christina walked over directly, then stretched out a finger and pointed on the steel plate, and a large amount of white foam immediately began to appear on the steel plate where Christina touched it. , and at the same time the steel plates began to soften and dissolve rapidly, it felt as if Christina's finger was a soldering iron and the steel plates were blocks of snow.

Before the steel plate melted through, I activated the team channel and said: "From now on, everyone will use the team channel to communicate, and you are not allowed to speak directly. You should also try not to make any noise in the cavity behind to prevent being intercepted by the enemy." Line of defense.”

Everyone answered in the team channel and understood what I meant, and then everyone waited quietly for Christina to open the way.

It didn't take long to melt through the steel plate. The key is to find a passage that we can drill through, which takes a little time. Come to Christina, there are many ways to break through this steel plate. Even if you specify the use of corrosive magic, there are still many ways, but the key problem is that general corrosive spells actually make some sounds. Because the corrosion rate is too fast, a chirping sound will be made when any magic such as strong acid is used on the metal surface. And this kind of sound is obviously very easy to detect in such a quiet place.

In the end, Christina could only choose a relatively quiet magic. It's a pity that the speed of this thing is really not flattering.

After finally opening a hole big enough for us to pass through, we finally confirmed our previous guesses. There is indeed a cavity behind the steel plate, but the structure is much more complex than we imagined.

In fact, what we saw after opening the steel plate was not a huge underground space, but two conical rooms on the left and right. There is a metal dividing line about one-third to the left of the hole Christina made. There is a space on each side of this dividing line. The side of this space facing us is a regular hexagon, and then as it extends to the distance, this hexagon gradually shrinks and finally gathers a little, forming a flat vertebral space.

Although the overall appearance is not easy to understand, if you isolate this room, you can find that its shape is actually very similar to a simple loudspeaker rolled out of iron sheet. The structure of this east-west body is actually not complicated, but with so many of these structures attached to the gaps between the city and the underground structures outside the city, the amount of work is quite astonishing.

Although I am not studying architecture, after seeing the structure of these two small rooms, I immediately guessed why the Banshee House designed such a structure.

First of all, these rooms do serve a similar function as a sound amplifier, but it is not an amplifier, but a sound collector. Whenever you roll any object with a certain hardness into a trumpet shape and point the small mouth at your ear, this thing can increase your hearing range to a certain extent. The room in front of you is actually an amplified sound collector. It relies on its own resonance structure to collect sound waves, then gathers them to the bottom of the cone-shaped structure, and then directly connects to the control center through a small tube.

One of the benefits of this design is that it can increase the sonic sensitivity. After resonance amplification, even small sounds can be heard. The second benefit is more obvious, that is, it can be positioned. We originally thought that the space behind the steel plate should be an integral interconnected structure. In this case, the other party can only hear whether someone has broken into the area behind the steel plate, but cannot determine the source of the sound. But it's different now. These individual cone-shaped rooms will only transmit the sound from their own location, and the sounds from other locations will not be heard. In this way, as long as the opponent numbers the sound collector pipe when building these things, they can easily find the specific source location of the sound, thereby accurately locating the enemy's invasion point.

This design can be said to be quite clever, and the biggest advantage of this thing is that it is completely passive, does not require additional equipment, consumes no energy, will not be disturbed, and more importantly, is difficult to detect.

It can be said that this kind of thing is an absolute nightmare for sneak attack intruders, because almost no one can pass through this kind of place completely silently, unless of course, like us, you can guess that there is a monitoring range behind this place, so as to control the noise.

The secondary function of these small, tapered structures is reinforcement.

Due to the stability of the vertebral body structure, these small rooms next to each other can actually function as support beams. And because each room is the same shape, they can spread the stress through structural strength. In other words, the strength of this thing must exceed the strength of its material, because it can disperse pressure to a great extent. On the surface, it looks like it has endured pressure that exceeds the limit of the material. In fact, for the internal material, the pressure at each position does not actually reach the limit.

This structure also has a third advantage, which is to completely isolate the inner and outer spaces. Due to the existence of these small closed rooms, the outer wall of this dungeon and the external structure we penetrated before are equivalent to being filled with a lot of fixed particle structures, and this structure plays a role similar to foam, which can Complete thermal insulation, sound insulation and isolation from all kinds of radiation.

This excellent design shows that the Russian engineering technology level is quite advanced. At least the underground city structure of this Banshee House is quite exaggerated. Although we have safely broken through a layer of steel plate. But after seeing the internal structure, I was even more amazed.

After Christina melted the steel plate in front of us, she turned around and added a dexterity spell to each of us. This prevents us from making loud footsteps due to our own weight, and Christina herself quickly moved to the tip of the vertebral structure and began to melt the steel plate in this place.

After carefully opening a large hole in one of the cone bodies, we entered the cone room in the second-layer structure behind it, but there was no sound collector feature here. Of course, we still need to keep quiet. Because the big holes that were opened before are actually connected to the rooms outside that have sound collector functions.

Get to the bottom of the cone room over here. Christina used her hands to lift the steel plate in front. Then he closed his eyes and sensed it for a while, then turned to me and said through the team channel: "President, there may be some trouble here."

"What's wrong?" I asked as I approached, and Ichiro Tsunoda, Matsu Masagi and the others quickly gathered around.

Christina pointed directly at the wall and said: "Let go of your magic sense and feel what's going on behind this wall."

After hearing Christina's words, we all quickly sensed the situation on the wall. What we felt surprised us, because there were actually dense magic circuits behind this wall.

The so-called magic lines are actually the same thing as wires. Of course, when I say the same, I mean they are similar in nature. In fact, there is a big difference between magic wire and electric wire. They transmit different things and have different body qualities. What they have in common is that they are all a kind of wire and a medium for transmitting energy. The only difference is that the nature of the energy transmitted is different.

Normally, a guild that can make magic lines must have an array master, and the complexity of the magic line depends on the level of the array master. The magic circuit networks our guild currently only makes are basically no different from large-scale integrated circuits, and their function lies in concentrating more magic into a smaller area with higher output intensity. .

However, the magic lines behind this wall are not used for this. In fact, the magic lines on the wall are actually alarms. They are buried in the wall. If you cannot sense the flow of magic, destroy the wall directly and break these magic lines at the same time. Then as soon as the magic lines are broken, The other party will know that someone has come in. Moreover, this kind of magic circuit alarms through the continuous transmission of energy, so even energy bodies like ghosts have no way to bypass this circuit, because once the energy body passes through this circuit, interference will occur, and The reaction to this phenomenon is also very obvious, at least enough to let the other party know that something has come in.

Some people may say that since we know the existence of magic lines, isn't it okay? That's right, if it's a simple magic circuit, if you know their existence and don't destroy it, then there won't be much of a problem. But the problem now is that the structure of these things is too complicated, and various lines are constantly using messy linking methods to create a three-dimensional maze-like structure. This makes it impossible for us to determine the specific direction of the lines and the strength of the magic power. Therefore, Even if these lines are discovered before, we can't simply rely on inserting magic signals to interfere with the operation of these things, because we simply don't know how to insert signals. After all, it is not a good idea to mess up the wiring without knowing the superior and subordinate relationships between the lines.

Faced with this complex structure, even magic masters like Christina frowned, but pure warrior players like Tsunoda Ichiro and Ma Hong were very relaxed. Anyway, it was all for them. I can’t understand it, no matter how complicated it is.

Although Ichiro Tsunoda and Maou couldn't understand, there were still many of us here who could. And because we could, we frowned and thought together. After all, if we wanted to get past, we would have to destroy this wall. If you want to destroy this wall and don't want to be discovered, you can only find a way to jump these connecting lines. but. before jumping these connections. We need to find their transmission structure, that is, know what the circuit diagram looks like, but the complex three-dimensional structure of this thing is definitely not that simple to analyze clearly. And as long as any line is in the wrong order, an alarm will be triggered.

"This thing is too complicated!" Song Zhenghe said.

Chihuo Longji also rubbed her eyes and said, "I can't do it anymore. My eyes are all blurry. I can't touch this thing!"

Yingyu Shenchu ​​and August Xun also shook their heads and stepped aside. Like everyone else, they are completely unable to deal with this thing. The line is too complicated. If you rely on manual analysis, you will need scratch paper for written calculations, otherwise it will be difficult to figure out the specific direction of the circuit diagram. What's even worse is that the structure of these things is too dense, and there are no signs or anything on them. So if you are even slightly distracted, you will not be able to figure out where you were looking at before. And once this happens, it means that all your previous calculations are in vain.

"Are you kidding? This kind of thing is not made by humans, okay?" Jin Coin rubbed his eyes and squatted down after persisting for a few minutes. He really couldn't analyze it.

Compared to them, I am slightly better off. Because I am a dragon, I also have an electronic chip in my brain, so I can virtually image this circuit diagram in my brain like a computer, and then use the simplest knowledge similar to junior high school physics to talk about this circuit diagram. Simply simplify it into a standard circuit diagram, and then just find the upper and lower nodes and restore them to the corresponding positions on the original circuit diagram.

In fact, this kind of work mainly requires one person to analyze a lot of information simultaneously, and there is no way to rely on external devices to record what has been calculated before. This leads to people often calculating the latter and forgetting the previous, and the result is the result of repeated calculations. No results.

Obviously, the people who designed this thing intentionally designed such a structure. Their purpose is to confuse people so that you can't discover the structure of this thing, and there is no way to crack it.

It took me five minutes to find all the safe nodes on this thing, so I said directly to Christina who was still calculating: "Don't forget it, I have found the safe line."

"Tell me where it is." Christina did not immediately ask me how I calculated it in surprise like most people. On the one hand, it was because of her trust in me, and on the other hand, she was smart enough to know this kind of thing. Even if she calculated it, she would forget it if she didn't pay attention, so she didn't dare to interrupt my train of thought and asked me to tell her the location directly.

"Get out of the way. I spoke too slowly and didn't have time to cooperate. Let my demon pet come up."

Christina stepped aside without hesitation after hearing my words, and Ling appeared in front of us at the same time. Everyone present, including Ichiro Tsunoda, knew Ling. After all, this is my familiar that has appeared the most.

Because of the spiritual link, no language is needed to communicate between Ling and I. We can directly transfer our thoughts, so I can send all the calculation results instantly without converting into a language mode to describe the picture.

Ling's magic control is definitely no worse than Christina's, so after getting the detailed drawings I calculated, he immediately took action like lightning and drew a suspended magic circle in the air with his bare hands. This kind of void drawing ability is the ability of a top magician, and ordinary magicians cannot do it at all. After drawing the magic array directly in the air, Ling quickly clicked on it a few times, fixed the magic probe on the magic array, and then connected all the magic points. Of course, these links are not simply one-to-one, nor are they all connected together, but are connected according to the circuit diagram I calculated before, because magic circuits also have parallel and series connections, and compared with the circuit diagram. Magic lines also have an additional connection type called reverse connection, which is a more complex link type. Therefore, the specific jumpers need to be connected according to my drawings.

Ling's speed was very fast, and it only took a few seconds to complete all the connecting lines. After that, she added a black light ball in the center of the suspended magic circle. The front end of this light ball is exactly on the same plane as the top of the magic probes. This means that when the magic array moves as a whole toward the magic lines on the wall, when the probes penetrate the key points in the lines, At the moment of the node, the black magic ball in the center will also simultaneously destroy the jumped part of the line in the center.

The reason for this arrangement is to avoid the situation where the other party's detection equipment is more sensitive and can detect that there are additional lines connected in parallel in the line. After all, some of the magic circles in our guild have similar functions. Therefore, the possibility that the Russians also have similar technology cannot be ruled out.

After placing all these things, Ling decisively took it easy behind the magic circle. The magic circle immediately flew forward and covered the wall in an instant. At the same time, a big hole was swallowed up in the center of the wall by the black magic light ball.

"Does this count as a success or not?" Looking at the current situation. Ichiro Tsunoda asked with some uncertainty.

Chihuo Longji said from the side: "I don't understand it at all, just like you."

Christina explained at this time: "It should be successful. Because the magic circuit is still running. There is no change. If the alarm was activated just now, the flow of magic power in the circuit here will always change somewhat." .Of course. We do not rule out the possibility that the structure of this magic circle is too large to automatically filter out clutter."

Ichiro Tsunoda obviously didn’t understand what Christina was saying at all, but that didn’t stop him from figuring out that we could pass.

After roughly confirming that there shouldn't be much problem with this thing, we began to carefully drill through the hole in the wall.

After the magic circle created by Ling just penetrated the wall, the black ball of light in the center disappeared, and now there is only a hole left there. After we passed through, we found ourselves entering a corridor, but this corridor was rather strange. It seemed to surround the entire city like a ring road, and it was very wide. We suspect that this is probably the same as the outer ring kilometers of an ordinary city. After all, the first few defenses are exaggerated enough, and it doesn’t make much sense to continue to set up more levels later.

"Are we in now?" Looking at the empty passage, Ichiro Tsunoda asked with some uncertainty.

In fact, we are not sure whether we have entered, because the dungeon of Banshee House seems to have been greatly adjusted since the last time I was here. At least I have never seen this ring road before. In fact, this ring road is not only very wide, but also divided into several levels. They are not separated by walls, but use a structure similar to an overpass. From where we are now, we can directly see the adjacent passages on several floors above and below. However, there are no people or materials passing through these passages. It feels like entering a ghost town.

"Why does something feel wrong here?" Song Zhenghe finally discovered the problem.

I frowned and looked around, and then suddenly found a big hole that was obviously burned out on a wall not far away. The big hole didn't look like it was left during the construction process, but it looked like it was caused by an attack or explosion.

"Why does this place feel like it was attacked?" After I found the burn mark, others also saw it. After all, the distance was not very far, and the mark was obvious. There is a large area of ​​black on the blue-gray wall, and the surrounding lights are relatively bright, so naturally everyone can see it.

"If we hadn't been able to contact the people outside, I would have thought that the feint attack troops above did not follow the plan and came in ahead of us!" Zhenhong said.

"Perhaps the temptation really came in before us." Christina said: "I sensed a large amount of active magic elements in the air. This is a trace of the large-scale use of magic that just occurred."

"Is there really someone who got there first?" I looked at Christina in surprise and asked, "Can you sense something else?"

"No, this information feels like it was a long time ago." Christina said.

"It seems that there is only one way to know the truth." Song Zhenghe said: "Let's go in and take a look? There is no use waiting here anyway." (To be continued.)
