Chapter 277 Second Floor! Ma Laogou's Invitation!

"It's just a biological virus that completely penetrated the sky barrier, causing the defense line that humans thought was indestructible to collapse instantly"

"But judging from the time when humans moved to the New World, the biological virus only came in the ninth year"

"Now I have a complete virus vector and so much time, biological virus"

"Don't worry!!"

When Su Mo thought about the previous two times he entered this relic and fought with the black dog mad bull, he was not directly bitten or scratched, and he felt fortunate. Google search reading

At the same time, thinking about the other mutant creatures that are still trapped in the core of this relic, Su Mo couldn't help but pound the ground with his fists, feeling lucky for coming directly to Ma Fei's shelter before.

These living mutant creatures can't die so easily.

In the face of biological virus disasters in the future, this is a "treasure" that can be dissected and analyzed in advance!

As long as a complete biological laboratory is established, the corresponding virus template is extracted, and a serum antidote is developed.

Biological virus, can that still be a problem?

Even if the biological virus mutates to a higher level, after nine years, Su Mo is confident that he has already established a complete prevention and control organization, and it is not impossible to go directly to the "sky" to turn the creatures running on the ground into fools.

"From this point of view, the most important point of this level 17 core is still this sky defense system and virus biological template"

"As long as a sky can be built in the real world, or a replica, it can resist ordinary disasters completely"

"I have a system, and I can completely integrate other technologies to completely improve the design concept of the sky"

After solemnly putting away the mayor's manual that records the operation of Liangfang Town and putting it in a position in the storage space that does not need to be moved, Su Mo stood up and began to carefully look at this room where the treasure may be hidden.

The control system of the sky is in the mayor's room.

Judging from the furniture arrangement on the first floor, this should be where Ma Fei usually handles government affairs. Occasionally, he will meet with others here to discuss matters related to the development of Liangfang Town, so the mayor's manual will be placed on the first floor.

But Su Mo did not let go of any place in the mayor's office where information might remain. Starting from the floor of the first floor, Su Mo insisted on "scraping the ground three feet deep" in every place.

Of course, there were gains. Among them, Su Mo found two letters used for material handover again and extracted an important piece of information.

The coordinates of Hanwu City, which had traded with Liangfang Town, and the coordinates of Yangliu City.

"At present, the core of Liangfang Town can manifest ruins in my depression for some reason."

"But its real prototype should be at the wasteland coordinates prompted by the system."

"If I can locate the real location coordinates of Liangfang Town, after finding a marking method and going to the new world, I may be able to trace the location of these two cities."

Similarly, after taking the two letters recording the coordinates back to the storage space and calling Moore to the iron door from the first floor to the second floor, the first challenge was finally placed in front of Su Mo.

No matter how weak Ma Fei was, he was still a level 17 boss. No matter how crooked the technology tree of Yan Country was, it also developed a good means of disaster avoidance such as the Sky Barrier.

If the first floor is a reception room, which seems to have no defense, then the heavy iron door on the second floor is a necessary step to open the "treasure".

He tried to knock on it, and heard the heavy sound that did not convey any sound at all, which made Su Mo a little confused.

This iron door with a sound is more difficult to deal with than the stone door of the underground shelter. The thickness is predicted to be at least ten meters, which belongs to the physical type of disaster avoidance method of piling materials.

Without qualified instruments, or without corresponding means of attack, this door alone can stump countless people.

Using such a simple and crude method to serve as the first line of defense for living in the shelter, it must be said that Ma Fei is also a coward.

As for the blasting breakthrough from the outer perimeter of the small building.

Thinking of this, Su Mo walked out of the first floor and began to carefully look at the main range structure of the entire small building.

The four-story building is not high, only about twelve meters, which is the height of the three cores of the shelter stacked together.

But this small building has a very buggy place

According to the construction level of a single floor, the thickness of the outer wall of this small building should be about ten to fifteen meters, which is difficult to knock down even by blasting.

And even if it can be blasted, if it is punished by a hundred or eighty days, it will be considered as a crime of offending the mayor, which is really bad.

"How about trying to blast directly from inside the house?"

It is impossible to blast outside, so Su Mo walked back to the house and looked at his remaining time currency. He quickly eliminated this dangerous idea.

It is impossible to leave.

But if I don't take it, this trip will be in vain.

The computer is gone, so I should take something else or learn some other information this time.

This is not the same as going into a treasure mountain with nothing, which is a huge loss!

"What good way is there to get through this iron door and get to the second floor in the usual way!"

"Chemical?"

"Drill?"

With twenty hours left, Su Mo simply sat in front of the window, looked at the sky like a fire for a few times, and then closed his eyes and thought about how to break through.

It is not impossible for chemicals to corrode iron, but the most important raw materials are not available.

Drills are even less reliable, so it is more realistic to switch to fixed-point blasting.

From the perspective of a modern person, facing a pure iron security door that is more than ten meters thick and has no key

Suma is a little helpless!

Moore, who was standing by, also discovered the same thing as Sumo, as well as this iron door.

For the Thunder Bear Warriors, they would not think about how to get in by tricks.

Spitting out two mouthfuls of saliva, rubbing his hands, Moore directly sat in front of the iron door and shoveled with a three-pointed two-edged knife.

Unfortunately, every time he shoveled, in addition to the sparks of friction, the iron door remained motionless!

"Moore, stop shoveling, you can't dig even if you dig"

"Fuck, I'm in a misconception!"

"I can use magic to deal with magic!"

The heavy iron door does not seem to be able to be broken through with ordinary tools, but as Sumo's mind moved, a flashing iron pickaxe with excellent quality appeared in his hand, and everything seemed simple.

The quality of iron is 3.

The special effect of the fine iron pickaxe is that for materials below level 5, as long as the critical hit has a certain probability of producing the shattering special effect.

Once triggered, the outer iron block will break like tofu. As long as the knocking continues, let alone ten meters.

Even if it is fifty or sixty meters, Su Mo is confident that he can dig through it today!

"Moore, Moore, you are such a clever little ghost!"

Patting Moore on the back, looking at the latter's confused expression, Su Mo laughed and went to the wall next to him to try it first.

Sure enough, the material level of the wall was judged to be above level 5. Even if the iron pickaxe triggered the special effect, the wall did not move except for the wall dust falling down.

"It seems that it is impossible to get a bug, so I can only dig step by step!"

It takes five minutes to knock a pickaxe on the wall, and twenty minutes to knock on the iron door.

One day's time currency can leave 72 pickaxes on the iron door.

In order to save money, Su Mo simply took out a unit of iron block from the storage space and began to knock slowly.

The light of the iron pickaxe's critical hit was very obvious. In addition to the bright light that would burst out from the pickaxe head, the hand holding the pickaxe could also feel a unique power.

Whenever a critical hit was triggered, Su Mo would raise his hand and smash the iron door with a pickaxe, bringing down an iron block about the size of a human head.

This was a patient job. Fortunately, there was still a lot of time now, so Su Mo was not in a hurry. When he was tired of knocking, he sat down to rest for a while, drank some water, and ate some dry food.

After resting, he worked hard again.

"You are worthy of being Lao Gou. A two-meter-thick iron door weighs at least 20 to 30 tons."

"If it were an ordinary residential building, it would not be able to bear such a weight. There are so many doors built. Looking at the width of the wall outside, there must be nearly ten doors. You are worthy of being a fellow worker!"

I don't know what material the main body of the shelter is made of, and the load-bearing capacity is extremely terrifying.

After spending a day and a half to break two doors that were more than two meters thick, another door appeared. Su Mo was amazed and had a basic understanding of level 17.

The 2-meter floor height created by the system gave enough space for tricks.

The height of the first floor was 4m, and the iron door was designed in a corridor style. After digging through two doors, Su Mo calculated and found that he had only risen half a meter in height.

At this point, let alone how harsh the upgrade conditions were, just this life-saving consciousness is worth learning.

This time, let alone going to the new world, I will upgrade the materials of the underground shelter directly, and the entrance door will be so thick!

After knocking for another two or three hours, I opened the panel and found that there were only twelve hours left. Su Mo did not rest, but took out the mountain and sea scroll card to restore his strength and continued to dig forward.

In ancient times, there was Yugong moving mountains.

Today, there is Su Mo chiseling doors.

Countless broken iron blocks were dug out, and then Oreo pushed a homemade cart to dump them in the yard.

Old lady Doudou saw Oreo of the same kind, and kept lying beside him and chattering.

The ruins that were extremely dangerous in the eyes of others became a special labor meeting for Su Mo.

He kept digging, and whenever a critical hit was triggered, Su Mo would swing at the iron gate next to him.

The repetitive mechanical labor for more than ten hours was extremely exhausting.

Fortunately, Su Mo, who had lived in the wasteland for a month, now had a lot of endurance and survived.

Bang!

Buzz

Another skilled critical hit hit the side with a pickaxe, but this time, Su Mo finally smiled on his gray and black face.

The iron gate finally made a sound!

The sound meant that the back was no longer a passage, but an open place, which produced an echo!

At this level, it only took more than an hour of digging to open this passage!

With a goal, Su Mo felt as if there was an endless flow of power from all directions of his body, and his silent brain seemed to be injected with a spring of life.

Half squatting, the speed of the pickaxe in Su Mo's hand suddenly increased, and even sparks appeared on the deformed iron block.

Boom!

Boom!

Boom!

Pickaxe after pickaxe, continuous iron filings fell off the iron door, and Moore dug them out with both hands, leaving Su Mo with the largest space to dig.

Finding a point, Su Mo covered his head and waved wildly.

Finally, when there were still six hours left in the countdown of this relic, with a crash.

The door

collapsed!

Countless dust was raised at this moment, accompanied by the iron blocks falling to the ground, and the dull echoing sound continued to spread.

Although he was very happy, looking at the depths of the dark room, Su Mo still rested cautiously for half an hour, ensuring that his mental and physical state had recovered to his peak, and then called the Tibetan mastiff Doudou.

"Be careful when you go in later. If there is any danger, retreat in time!"

Touching the silly dog's head and looking at its well-behaved appearance, Su Mo bent his body slightly and prepared to run away at any time.

There are hundreds of engineering robots on the first floor. If there are really expected attack robots on the second floor, Su Mo would not dare to confront the mysterious side technology of the future head-on even if he had a hundred courage.

Fortunately, the expected attack did not break out. When Doudou stepped into the second floor, a strong light suddenly broke out from the ceiling of the second floor, illuminating the entire darkness.

Having been accustomed to the darkness for a long time, this sudden light made Su Mo close his eyes involuntarily.

But just when Su Mo had just reacted and had no time to retreat, a deep male voice sounded in the shelter.

"Welcome, the future"

"Welcome to my shelter!"

"Come in, since you can pass my first test, you are also qualified to know something!"

This male voice seemed to have endless charm, and the moment it sounded, Su Mo couldn't help but stop.

Human?

No, this is Ma Fei?

Is this Ma Fei, the mayor of Liangfang Town?

With curiosity, Su Mo tried to stick his head out of the iron door, and then Su Mo saw the most shocking scene from Earth to now:

On the second floor, there are not only high-end desktop computers that he has been thinking about day and night, piled up in the corner like sundries.

There are also transparent pipes with a diameter of one meter, which are densely spread on the ground like blood vessels, transporting the water-like energy that has been materialized into dark blue.

At the end of the sight, there is a whole wall, which is composed of small robots that have been seen before.

Unlike the previous engineering machinery, these little men had nothing in their hands and seemed to be in a dormant state, allowing energy to hit them, emitting waves of mysterious phenomena like water ripples.

But all this could not attract Su Mo's attention.

Because, in the center of the room, there was a large cube, at least 4m*4m in size.

Su Mo was not unfamiliar with this thing, and he had just seen it in his dream recently, and he was envious of it in his dream.

"Very good, vertical missile launcher, I admit that I was really tempted this time!"
