Chapter 274

"Just a biological virus, it completely broke through the sky barrier, making the defense line that humans think is indestructible collapse smoothly."

"But judging from the time when humans moved to the new world, the biological virus only struck in the ninth year."

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

"Don't worry!!"

Su Mo felt a burst of joy at the thought that he had not been directly bitten or scratched by black dog and mad cow when he entered the ruins twice before.

At the same time, thinking about other mutant creatures still trapped in the core of this relic, sumo couldn't help clenching his fist and pounding the ground, feeling lucky for coming directly to Ma Fei's shelter before.

These * * mutant creatures can't die so easily.

In the face of biological virus disasters in the future, this is the "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, is that still a problem?

Even if the biological virus mutates to several grades, after nine years, sumo is confident that it has already established a complete prevention and control organization, and even goes directly to the "sky" to make these creatures running on the ground become Han PI, which is not impossible.

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

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

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

Solemnly put away the mayor's manual recording the operation of LiangFang town. After summing it up to a location in the storage space that does not need to be transferred, Su Mo stood up and began to look carefully at the room where the treasure may be hidden.

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

Judging from the furniture layout 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 will be placed on the first floor.

But Su Mo didn't let go of any place where information might remain in the mayor's room. From the first floor, Su Mo insisted on "scraping the ground three feet" at every place.

Of course, the harvest is not without. Among them, sumo once again found two letters for material handover, and extracted an important information.

Hanwu coordinates traded with LiangFang town and Yangliu coordinates.

"At present, I don't know why the core of LiangFang town can show traces in my depression."

"But its real prototype should be in the coordinates of waste soil prompted by the system."

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

Similarly, after taking these two letters recording coordinates back into the storage space and greeting Moore to the iron gate on the first to second floors, the first challenge was finally placed in front of Su mo.

No matter how weak Ma Fei is, he is also a seventeen level boss. No matter how crooked the technology tree of Yanguo is, he has also studied the sky barrier, a good means specially used to avoid disasters.

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

Trying to go up and knock, Su Mo was a little embarrassed by the thick sound that didn't convey the sound at all.

The sound of the iron gate is even more difficult than the stone gate of the underground refuge. The predicted thickness is at least 10 meters up, which belongs to a physical way of stacking materials to avoid disasters.

Without qualified instruments or corresponding attack means, this door alone can defeat countless people.

Using such a simple and crude means to act as the first line of defense in the shelter, it has to be said that Ma Fei is also old-fashioned.

As for the outside of the small building, the explosion broke in.

Thinking so, Su Mo walked out of the first floor and began to carefully examine the main structure of the whole building.

The four storey building is not high, only about 12 meters high. It is the height of the three refuge cores stacked together.

But there is a very bug in this small building

According to the construction level of the first floor, the thickness of the outer wall of this small building should be about 10 to 15 meters, which belongs to the range that blasting is difficult to blow down.

And even if you can bang, in case you get a hundred and Eighty Day punishment and count it as a crime of bumping into the mayor, you'll pull your crotch.

"How about trying to explode directly from the house?"

Unable to blast outside, he walked back to the house and looked at his only time money. Su Mo quickly eliminated this dangerous idea.

It's impossible to go.

But don't take it. This trip is not in vain.

The good computer is gone. This wave should not take anything else, or learn some other information.

This is not equal to empty into Baoshan, blood loss!

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

"Chemistry?"

"Drill?"

While there were still 20 hours left, Su Mo simply sat directly in front of the window, looked at the burning sky for a few times, and began to close his eyes and think about how to break in.

Chemical corrosion of iron is not impossible, but the most important raw material is none on hand.

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

Starting from the thinking of a modern person, we face a pure iron anti-theft door that is ten meters thick and has no key

Sumo is a little helpless!

Moore on the side also found the same as sumo's and the iron door.

For the mind of thunder bear warriors, they will not think about how to enter by chance.

Spit out two mouthfuls and rub his hands. Moore directly began to sit in front of the iron door and shovel with a three pointed two edged knife.

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

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

"Lying in the trough, falling into a misunderstanding!"

"I can use magic to deal with magic!"

The heavy iron door did not seem to be able to break through with ordinary tools, but with Su Mo's mind moving, when a shining iron pick appeared in his hand, everything seemed to be simple.

The quality of iron is at 3.

The special effect of excellent iron pick is less than 5 materials. As long as you critical hit, you have a certain chance to produce fragmentation effect.

Once triggered, the iron pieces on the periphery will break like tofu. As long as you keep knocking, let alone ten meters.

Even fifty or sixty meters, Su Mo is also confident that he has dug through it today!

"Moore, Moore, you're such a clever boy!"

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 grade of the wall was judged to be above 5. Even if the iron pick triggered the special effect, the wall did not move except brushing the falling wall ash.

"It seems that you can't get stuck. You can only dig it step by step!"

It takes five minutes for a pickaxe to knock on the wall, and 20 minutes to knock on the iron door.

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

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

The light of the iron Pick's critical strike is very obvious. In addition to a burst of light when passing the pick, the hand holding the pick can also feel a unique force.

Whenever a critical hit is triggered, Su Mo will raise his hand and hit the iron door with a pick, bringing down an iron block about the size of a head.

It's a patient job. It's just that there's still a lot of time now. Su Mo is not in a hurry. When he's tired, he sits down and takes a rest, drinks water and eats dry food.

After a rest, there was another burst of hard work.

"I thought it was only about ten meters, but now it seems that this iron gate is a full twenty meters thick, worthy of being a fellow believer!"

Seeing that it had taken three days for the currency to knock out a full 11 meter long channel, the iron gate still looked endless. Su Mo admired it and had a basic understanding of level 17.

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

This time, without saying anything else, after going to the new world, the materials of underground shelters will be upgraded directly, and the entrance door will also be increased to 20 meters!

After knocking for twoorthree hours again, he opened the panel and found that there were only twelve hours left. Su Mo didn't rest. He directly took out the Shanhai scroll card to recover his strength and continued to dig forward.

In ancient times, Yugong moved mountains.

Today, Su Mo chisels the door.

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

The old lady Doudou, however, saw the same kind of Oreo and kept lying on the side talking.

In the eyes of others, the dangerous relics have become a Labor Conference of different faces here in sumo.

Keep digging. Whenever a critical hit triggers, Su Mo waves it on the iron door next to him.

Repetitive mechanical labor lasting for more than ten hours is extremely laborious.

Fortunately, Su Mo, who has lived on the waste soil for a month, is now more tolerant than before, and has just survived.

Bang!

Hum

It was another skilled critical hit, and a pickaxe hit beside him, but this time, Su Mo's face was all gray and black, and finally showed a smile.

The iron gate finally has a sound!

The sound means that the thickness has been reduced to within 35 meters. It only takes more than an hour to dig, and this channel can be chiseled!

With the goal, Su Mo only felt that there seemed to be a steady flow of power coming from all sides of his body, and the silent brain seemed to inject a living spring.

Squatting half, the speed of the iron pick held by Su Mo suddenly accelerated, and even sparks appeared on the deformed iron block.

Dong!

Dong!

Dong!

Pick after pick, the iron scraps fell off the iron door and were dug out by Moore with both hands, leaving the largest space for Su Mo to dig.

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

Finally, when there were still six hours to count down the ruins, there was a crash.

door

Collapsed!

Countless dust was raised at this moment, and with the iron falling to the ground, the dull echo was constantly transmitted.

Although there were countless joys in his heart, looking at the dark room, Su Mo cautiously rested for half an hour to ensure that his mental and physical state had recovered to its heyday, and summoned the Tibetan mastiff Doudou.

"Wait, go inside. Be careful. If there is danger, get back in time!"

Touching the silly dog's head and looking at his clever appearance, Su Mo bent slightly and was ready to run 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 is to give Su Mo a hundred courage and dare not use the mysterious side technology of the positive hard future.

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

Accustomed 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 sounded in the shelter.

"Welcome, the future"

"Welcome to my refuge!"

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

This male voice seemed to have endless charm. At the first moment, Su Mo couldn't help pausing.

human beings?

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. Then, Su Mo saw the most shocking scene from the earth to the present:

In the second floor, there are not only high-end desktop computers that are long for, but also piles up in the corner like sundries.

It also has transparent pipes with a diameter of one meter, which are densely laid on the ground like blood vessels, conveying the water-like energy that has been provided with a ready-made dark blue.

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

Unlike previous construction machinery, these little people have nothing on their hands. They seem to be in a dormant state, allowing energy to hit them, emitting mysterious phenomena like ripples of water.

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

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

Su Mo is no stranger to this thing, and he has just seen it in his dream recently, and his eyes have been greedy in his dream.

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