MTL - My Post-Apocalyptic Shelter Levels Up Infinitely!-Chapter 274 2 layer! Ma Laogou's invitation!

"Just a biological virus, it completely penetrated the barrier of the sky, causing the line of defense that humans thought to be indestructible to collapse."

"But based on the time when humans moved to the New World, the biological virus only arrived in the ninth year."

"Now I have a complete viral vector, and so much time, biological viruses..."

"Not enough to worry about!!"

When he thought that he entered this ruins two times before and fought against the black dog and the mad cow, he was not bitten or scratched directly, and Sumo felt fortunate for a while.

At the same time, thinking about the other mutant creatures still trapped in the core of the ruins, Suma couldn't help clenching his fists and beating the ground, feeling lucky for coming directly to Ma Fei's sanctuary before.

These living mutants cannot 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 the serum antidote is developed.

Biological virus, can that still be a problem?

Even if the biological virus mutates to several grades, after nine years, Soma is confident that he has already established a complete prevention and control mechanism, and even goes directly to the "heaven" to turn these creatures running on the ground into idiots. It is not impossible.

"Looking at it this way, the most important point of this seventeenth-level core is this set of sky defense system and virus biological template"

"As long as you can build a sky dome in the real world, or imitate it, it is enough to resist ordinary disasters."

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

After solemnly putting away the mayor's manual, which recorded the operation of Liangfang Town, and summarizing it into a place in the storage space that did not need to be moved, Soma stood up and began to carefully look at the room that might be hiding treasures.

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

Judging from the furniture arrangement on the first floor, this should be the place where Ma Fei usually handles government affairs. He occasionally meets with others here to discuss the development of Liangfang Town, so the mayor's manual is placed on the first floor.

But Soma didn't spare any places in the mayor's room that might have left information. Starting from the floor of the first floor, Soma insisted on "scraping the ground three feet".

Of course, the harvest is not without it. Among them, Soma once again found two letters for the handover of materials, and extracted an important piece of information.

The coordinates of Hanwu City and Yangliu City that have been traded with Liangfang Town.

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

"But its real prototype should be in the wasteland coordinates suggested by the system."

"If I can locate the real location coordinates of Liangfang Town, after I find a way to mark it and go to the New World, I may be able to trace the origin to the location of these two cities."

In the same way, after returning the two letters with the coordinates to the storage space, and beckoning Moore to come to the iron gates on the first and second floors, the first challenge was finally placed in front of Soma.

No matter how weak Ma Fei is, he is still a level seventeen boss. No matter how crooked the technology tree of Yan Kingdom is, he has also researched the sky barrier, a good method specially used to avoid disasters.

If the first floor is a reception room, which looks defenseless, then this thick iron door on the second floor is a necessary step to open the "treasure".

He tried to go up and knock, and when he heard the thick sound that didn't convey the sound at all, Soma was a little bit troubled.

The iron gate of this sound is even more difficult to handle than the stone gate of the underground shelter, and the thickness is predicted to be at least ten meters above, which belongs to the physical method of stacking materials to avoid disasters.

Without qualified equipment, or in other words, without the corresponding means of attack, this door alone can stumped countless people.

Using such a simple and rude means to act as the first line of defense in the shelter, I have to say that this Ma Fei is also an old man.

As for the outside of the small building, blasting broke through.

Thinking so, Soma walked out of the first floor and began to carefully examine the main structure of the entire small building.

The four-story building is not high, only about twelve meters high. It 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 the first floor, the thickness of the outer wall of this small building should be about ten meters to fifteen meters, which is a range that is difficult to be knocked down by blasting.

And even if it can bang, if there is a time penalty of 180 days, and it is counted as a charge of assaulting the mayor, then it will be a crotch.

"Would you like to try to blast it directly from the house?"

It couldn't be blasted outside, so he walked back into the house, looking at the time and money he had left, Soma quickly eliminated this dangerous idea.

To go, it is impossible to go.

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

Said that the good computer is gone, this wave should not take other things, or learn some other information.

This does not mean entering Baoshan empty, blood loss!

"Is there any good way to get through this iron gate directly and enter the second floor in the usual way!"

"Chemical?"

"Drill?"

Taking advantage of the fact that there were still twenty hours left, Soma simply sat directly in front of the window, looked at the burning sky for a few times, then closed his eyes, thinking about how to break through.

It is not impossible to chemically corrode iron, but the most important raw material is not available.

The drill bit is even more unreliable, and it is more realistic to replace it with fixed-point blasting.

Starting from the thinking of a modern person, facing a pure iron security door with a thickness of more than ten meters and no key...

Soma is a little helpless!

Moore, who was beside him, also found Soma's and this iron door.

For the Thunder Bear Warriors' minds, they don't think about how to get in.

Spit out two mouthfuls of saliva, rubbed his hands together, and Moore directly began to sit in front of the iron gate with a three-pointed two-edged knife, shoveling up.

Unfortunately, every time the shovel is shoveled down, except for sparks of friction, the iron gate stays still!

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

"Fuck, I fell into a misunderstanding of thinking!"

"I can use magic to deal with magic!"

The heavy iron door really seemed impossible to break through with ordinary tools, but as Soma's mind moved, when a flashing iron pick of excellent quality appeared in his hand, everything seemed to be easier.

The quality of iron, in 3.

The special effect of the fine-grade iron pickaxe is the material below 5. As long as the crit hits, there is a certain chance to produce the fragmentation effect.

Trigger it once, and the surrounding iron blocks will shatter like tofu. As long as you keep tapping, let alone ten meters.

Even if it is fifty or sixty meters, Soma is confident that he will dig through it today!

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

Patting Moore on the back, seeing the confused expression on the latter's face, Soma laughed out loud and went to the wall next to him to try it first.

Sure enough, the material level of the wall is judged to be above 5. Even if the iron pickaxe triggers the special effect, except for the wall ash that falls down, the wall does not move at all.

"It seems that it's impossible to get stuck in bugs, so we can only dig it step by step!"

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

A day's time currency can leave 72 pickaxes on the iron gate.

In order to save money, Somo simply took out a unit of iron in the storage space and began to tap slowly.

The light of the iron pickaxe's critical strike is very obvious. In addition to the burst of light from the pickaxe, the hand holding the pickaxe can also feel a unique power.

Whenever a critical strike was triggered, Soma raised his hand and smashed a pickaxe on the iron gate, bringing down an iron block about the size of a human head.

This is a patient work, and there is still more time now, so Soma is not in a hurry, so when he is tired, he sits for a while, drinks water, and eats dry food.

After taking a rest, another burst of vigorous work.

"As expected of Lao Gou, the iron gate is two meters thick and weighs at least twenty or thirty tons."

"In other words, an ordinary residential building can't bear such a weight at all. With so many buildings built, looking at the width of the walls outside, there are nearly ten buildings, worthy of being a fellow!"

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

Seeing that it took a day and a half to spend money, after knocking on two doors with a thickness of more than two meters, and another one appeared, Soma admired and gained a basic understanding of the seventeenth level.

The 4.2-meter floor height created by the system gives enough space to play with flowers.

The height of the first floor is 2.4m, and the iron gate adopts a corridor-style design. After digging through two channels, Soma realized that he had only risen by half a meter.

At this point, not to mention how harsh the upgrade conditions are, this awareness of life-saving alone is worth learning.

When I go back this time, I will not say anything else. After I go to the New World, I directly upgrade the materials of the underground shelter, and the entrance door is also so thick!

After knocking again for two or three hours, he opened the panel and found that after only twelve hours left, Soma didn't rest, took out the Shanhai Painting Scroll card to recover his strength, and continued to dig forward.

In ancient times, there was a foolish man who moved mountains.

Today there is a Soma chisel door.

Countless pieces of broken iron were dug up, and then Oreo pushed the homemade cart and fell into the courtyard.

The old mother, Doudou, saw Oreos of the same type, and she was lying beside her and chatting non-stop.

In the eyes of other people, the ruins that were extremely dangerous, in exchange for Soma, turned into a different kind of labor conference.

He kept digging, and whenever there was a critical strike, Soma would wave it on the iron gate next to him.

Dozens of hours of repetitive mechanical labor is extremely labor-intensive.

Fortunately, Soma, who has lived in the wasteland for a month, has now become more patient than before, and he has just survived.

Boom!

hum.....

Another skillful crit struck with a pick beside him, but this time, Soma's face was all gray and he finally showed a smile.

The iron gate finally has a sound!

There is a sound, which means that the back is no longer a channel, but an open place, and an echo is generated!

At this level, it only takes another hour or so of excavation to open the tunnel!

With the goal, Soma only felt that there was a steady stream of power coming from all directions of his body, and his silent brain seemed to be injected with a living fountain.

Half squatting, the speed of the iron pick in Soma's hand suddenly accelerated, and even sparks appeared on the deformed iron block.

Boom!

Boom!

Boom!

One pick after another, the iron filings fell off the iron gate constantly, and Moore dug out with both hands, leaving the maximum space for Soma to dig.

Finding a spot, Soma covered his head and waved wildly.

Finally, when there were still six hours left in the countdown to the ruins, there was a clatter.

Door...

Collapsed!

Countless dust was raised at this moment, and as the iron blocks fell to the ground, the dull echoes continued to pass.

Although there were countless joys in his heart, and looking at the depths of the dark room, Soma cautiously rested for half an hour to ensure that his mental and physical state had returned to its heyday, and then summoned the Tibetan Mastiff Doudou.

"Wait to get inside, be careful with everything, and if there is any danger, come back in time!"

Touching the silly dog's head, looking at its well-behaved appearance, Soma bent slightly, ready to run away at any time.

There are hundreds of engineering robots on the first floor. If there is an expected attacking robot on the second floor, it will give Soma a hundred courage, and he will not dare to use the mysterious technology of the future.

Fortunately, the expected attack did not break out. When Doudou stepped into the second floor, a strong light suddenly erupted 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 Soma involuntarily close his eyes.

However, just when Soma had just reacted and had not had time to retreat, a thick male voice rang out in the shelter.

"Welcome, Future"

"Welcome to my sanctuary!"

"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 at the first moment of the sound, Soma couldn't help but stop in his footsteps~www.novelbuddy.com~Human?

No, this is Ma Fei?

This is Ma Fei, the mayor of Liangfang Town?

With curiosity, Soma tried to stick his head out of the iron gate. Then, Soma saw the most shocking scene from the earth to the present:

On the second floor, there are not only high-end desktop computers that I have been thinking about, but they are piled up in the corners like sundries.

There is even a transparent tube with a diameter of one meter, which is densely spread on the ground like blood vessels, and conveys the water-like energy that has been turned into a faint blue.

At the end of the line of sight, there is an entire wall made up of small robots that have been seen before.

Unlike the previous construction machinery, these little people didn't have anything in their hands. They seemed to be in a dormant state. They let the energy hit them, emitting mysterious phenomena like water ripples.

But all this did not attract Soma's attention.

Because, in the center of the room, there is a large squatting square, at least 4m*4m in size.

This thing is not unfamiliar to Suma, and he just happened to see it in a dream recently, and was jealous in his dream.

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