My Post-Apocalyptic Shelter Levels Up Infinitely! Chapter 274: 2 floors! Ma Laogou’s invitation!

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

"However, based on the time when humans moved to the New World, the biological virus did not come until the ninth year"

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

"It's nothing to worry about!!"

Thinking that he was not directly bitten or scratched by the black dog and mad cow when he entered this ruins for the first two times, Su Mo felt a burst of gratitude.

At the same time, thinking about the other mutated creatures still trapped in the core of this ruin, Su Mo couldn't help clenching his fists and pounding the ground, feeling lucky that he came directly to Ma Fei's refuge.

These living mutated creatures 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 has mutated to a few levels, after nine years, Sumo is confident that he has already established a complete prevention and control mechanism, and even went directly to the "sky" to turn these creatures running on the ground into idiots. 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 set up 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 handbook, which records the operation of Liangfang Town, and putting it away in the storage space that does not need to be moved, Su Mo stood up and began to carefully look at this room that might hide a treasure. .

The Skydome's control system is located in the mayor's room.

Judging from the furniture layout on the first floor, this should be where Ma Fei usually handles government affairs. He occasionally meets with other people here to discuss matters related to the development of Liangfang Town, so the mayor's handbook is put together. building.

However, Sumo did not let go of any possible information left in the mayor's room. Starting from the floor of the first floor, every Sumo insisted on "scraping the ground three feet".

Of course, the rewards were not without. Among them, Su Mo found two more letters for material handover and extracted an important piece of information.

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

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

"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 marking method and go to the New World, I may be able to trace the location of these two cities"

Similarly, taking the two letters with coordinates back into the storage space, and calling Moore to the iron gate on the first floor to the second floor, the first challenge was finally placed in front of Sumo.

No matter how weak Ma Fei is, he is still a 17th-level boss. No matter how crooked the Yan Kingdom's technology tree is, he has also researched the sky barrier, a good means for avoiding disasters.

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

Tried to go up and knock, listening to the thick sound that did not convey the sound at all, Su Mo felt a little bit difficult.

The iron door of this sound is more difficult to handle than the stone door of the underground shelter, and the estimated thickness is at least ten meters or more, which belongs to the physical method of stacking materials to avoid disasters.

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

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

As for the outer perimeter of the small building, blast it in.

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

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

But this small building has an extremely bug...

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

And even if it can be bombed, if there is a one-hundred and eighty-day punishment, and it is counted as the crime of assaulting the mayor, then it will be a shame.

"Why don't you try blasting directly from inside the house?"

There was no bombardment outside, so when he walked back to the house, looking at the time currency he had left, Su Mo quickly eliminated this dangerous thought.

Go, it is impossible to go.

But don't take it, wouldn't this trip be in vain.

The promised computer is gone, so why don't you get some other things in this wave, or get some other information.

This is not the same as entering Baoshan empty-handed, blood loss!

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

"Chemistry?"

"Drill?"

Taking advantage of 20 hours left, Su Mo simply sat in front of the window, looked at the burning sky, and began to close his eyes, thinking about how to break through.

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

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 anti-theft door that is more than ten meters thick and has no key...

Sumo is a little helpless!

Moore on the side also found Sumo's and the iron door.

For Thunder Bear fighters, they don't think about how to get in by tricks.

After spitting out two mouthfuls and rubbing his hands, Moore sat in front of the iron gate and shoveled with a three-pointed two-edged knife.

It's a pity that every time the shovel is shoveled, except for sparks of friction, the iron door remains motionless!

"Moore, stop shoveling, even if you dig, you won't be able to dig..."

"Fuck, I've fallen into a misunderstanding!"

"I can use magic to deal with magic!"

It seemed that the thick iron door could not be broken through with ordinary tools, but when Su Mo thought, an iron pick with excellent quality appeared in his hand, everything seemed to be easier.

The quality of iron, in 3.

The special effect of the elite-level iron pickaxe is a material below 5, as long as it is critically hit, there is a certain chance of producing a fragmentation special effect.

Once triggered, the surrounding iron blocks will shatter like tofu, as long as the knocking continues, let alone ten meters.

Even fifty or sixty meters, Su Mo 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 latter's bewildered expression, Su Mo laughed out loud, 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 5. Even if the iron pick triggered the special effect, the wall remained motionless except for the dust that fell from the wall.

"It seems that if you want to get stuck in the bug, it should be impossible, you can only dig it step by step!"

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

A one-day time currency can leave 72 pickaxes on the iron gate.

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

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

Whenever a critical strike was triggered, Somo would raise his hand and smash a pickaxe on the iron door, bringing down an iron block about the size of a human head.

This is a job of patience, since there is still more time now, Su Mo is not in a hurry, he sits and rests for a while when he is tired, drinks water and eats dry food.

After resting, it was another burst of hard work.

"I thought it was only about ten meters, but now it seems that this iron gate has a thickness of twenty meters or more. It is worthy of being a fellow!"

Seeing that it took three days to knock out an eleven-meter-long passage, and the iron gate still looked like there was no end, Su Mo admired it, and at the same time had a basic understanding of the seventeenth level. know.

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

Going back this time, not to mention anything else, after going to the New World, the material of the underground shelter will be upgraded across the board, and the entrance door will be increased to 20 meters!

After typing for another two or three hours, he opened the panel and found that only 12 hours were left, so Sumo didn't rest. He took out the Mountain and Sea Picture Scroll card to recover his strength, and continued to dig forward.

In ancient times, the Foolish Old Man moved mountains.

Today there is a Suma chiseled door.

Numerous pieces of shattered iron were dug out, and then Oreo pushed the self-made trolley and dumped it in the courtyard.

Old Mama, Doudou, saw Oreo of the same kind, lying beside her and chattering non-stop.

In the eyes of others, the ruins are extremely dangerous, but in Somo's place, they turned into a special labor meeting.

Keep digging, whenever a critical strike is triggered, Somo will swing at the nearby iron gate.

The repetitive mechanical labor of more than ten hours is extremely labor-intensive.

Fortunately, Sumo, who has lived in the wasteland for a month, now has a lot of endurance, so he insisted on holding on.

Boom!

Buzz...

It was another skillful crit pickaxe hitting beside him, but this time, Su Mo finally showed a smile on his already gray and black face.

The iron gate finally has a sound!

There is a sound, which means that the thickness has dropped to less than three to five meters. It only takes another hour of excavation, and this passage can be dug open!

With a goal, Su Mo felt as if a steady stream of power was pouring in from all directions of his body, and his silent brain seemed to be injected with a living spring.

Crouching halfway, the pickaxe in Sumo's hand suddenly accelerated, sparks even appeared on the deformed iron block.

Boom!

Boom!

Boom!

With one pick after another, iron filings fell off the iron gate and were dug out by Moore with both hands, leaving the largest space for Sumo to dig.

Finding a spot, Somo swung wildly with his head covered.

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

Door...

Collapsed!

Countless dust was raised at this moment, and as the iron pieces fell to the ground, the dull echoing sound continued to pass.

Although there were countless joys in his heart, looking at the depths of the dark room, Su Mo rested cautiously for half an hour to ensure that his mental and physical state had returned to its prime, and then called Doudou, a Tibetan mastiff.

"Go inside later, be careful, if there is danger, get back in time!"

After stroking the silly dog's head, seeing its cute appearance, Su Mo bent slightly, ready to run away at any time.

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

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

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

However, just before Su Mo had time to retreat, a thick male voice resounded in the shelter.

"Welcome, Future"

"Welcome to my sanctuary!"

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

This male voice seemed to have endless charm. At the first moment when it sounded, Somo couldn't help but stop in his tracks~IndoMTL.com~Human?

No, this is Ma Fei?

Is this Ma Fei, the mayor of Liangfang Town?

Out of curiosity, Su Mo tried to poke his head out of the iron gate, and then, Su Mo saw the most shocking scene from the earth to now:

On the second floor, there are not only high-end desktop computers that you have been yearning for, but they are piled up in the corner like sundries.

There are also transparent pipes with a diameter of one meter, which are densely laid on the ground like blood vessels, transporting the water-like energy that has been embodied 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 machines, these little people don't have anything in their hands, and they seem to be in a dormant state, allowing energy to hit them, emitting a mysterious phenomenon like water ripples.

But all of this did not attract Su Mo's attention.

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

Su Mo is no stranger to this thing, and he just happened to see it in a dream recently, and he was greedy in the dream.

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