My Post-Apocalyptic Shelter Levels Up Infinitely!

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

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

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

　　 "Not to worry!!"

　　 At the thought of entering this ruin the previous two times, and fighting against the black dog mad cow, and not being bitten or scratched directly, Somo felt fortunate.

　　 At the same time, think about the other mutant creatures still trapped in the core of this ruin. Sumo couldn't help but clenched his fist and thumped the ground, feeling lucky that he came directly to Ma Fei's refuge before.

　　 These living mutant creatures can't die so easily.

　　 Facing the biological virus disaster in the future, this is the "treasure" that can be analyzed 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, Somo is confident that he has already established a complete prevention and control agency, and even went directly to the "sky" to make these creatures running on the ground become a mess, it is not impossible.

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

　　 "As long as a sky dome can be built in the real world, or it is an imitation, it is enough to resist ordinary disasters."

　　 "I have a system, and I can add and integrate other technologies to completely perfect the design concept of Skydome"

　　 Solemnly put away the mayor's manual that records the operation of Liangfang Town, and after summarizing it to a position in the storage space that does not need to be moved, Somo stood up and began to look carefully at this room where the treasure might be hidden.

The control system of 　　 Sky Dome is 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 manual will be placed on the first floor.

　　 But Somo did not let go of any possible residual information in the mayor's room like this. Starting from the first floor, every Somo insisted on "scraping the ground three feet."

　　 Of course, the harvest is not without it. Among them, Somo once again found two letters used to transfer materials, and extracted an important piece of information.

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

　　 "At present, the core of Liangfang Town doesn't know why it can manifest the ruins in my depression"

　　 "But the real prototype should be in the wasteland coordinates indicated by the system"

　　 "If I can locate the real location coordinates of Liangfang Town, after finding a marking method, after I go to the New World, I may be able to trace the location of these two cities."

　　Similarly, the two letters with the coordinates recorded were returned to the storage space, and Moore was greeted to come to the iron gate on the first to the second floor. The first challenge finally came to Somo.

　　 No matter how weak Ma Fei is, it is also a seventeenth-level boss. No matter how crooked the science and technology tree of Yan Nation is, he has also researched the sky barrier, a good method specially used to avoid disasters.

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

　　 tried to go up and knock, listening to the heavy sound that didn't convey the sound at all, Sumo was a little bit puzzled.

　　 The iron gate of this sound is more difficult to handle than the stone gate of the underground refuge, and it is predicted to be at least ten meters thick. It is a physical type of disaster avoidance method.

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

　　 Using such a simple and crude method to act as the first line of defense for living in the refuge, I have to say that this Ma Fei is also Lao Gou.

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

　　 Thinking this way, Somo stepped out of the first floor and began to carefully examine the main structure of the entire small building.

　　 is a four-story building, not high, only about twelve meters high. It is the height of the three cores of the refuge stacked together.

　　 But this small building has a very 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 is within a range that is difficult to knock down by blasting.

　　 And even if it can be blasted, if a one hundred and eighty days time penalty is brought out, which is counted as a charge of ramming the mayor, then it will be slapped.

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

　　 I couldn't blast outside, walked back to the house, and looked at the time and currency he had left, Suma quickly eliminated this dangerous thought.

　　Go, it is impossible to go.

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

　　I said that the good computer is gone, so I don’t need to take other things or learn other information in this wave.

　　 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?"

　　 While there were still twenty hours left, Somo simply sat in front of the window, and after a few glances at the burning sky, he closed his eyes and thought 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 switch to fixed-point blasting.

　　 Starting from the thinking of a modern person, facing a pure iron security door that is more than ten meters thick and has no key...

　　 Somo is a little helpless!

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

　　 For the thinking of Thunder Bear Warriors, they don't think about how to enter by tricks.

　　 spit out two saliva and rubbed his hands, Moore directly began to sit in front of the iron gate with a three-pointed two-edged knife, and shoveled it ding-ding.

　　 It's a pity, every time you shovel down, except for sparks of friction, the iron gate stays still!

　　 "Moore, stop shoveling, you just dig, you can't dig..."

　　 "Fuck, I'm in a misunderstanding of thinking!"

　　 "I can use magic to deal with magic!"

　　 The heavy iron gate does not seem to be able to break through with ordinary tools, but as Somo's thoughts move, when a flashing fine quality iron pick appears in his hand, everything seems simple.

　　The quality of iron is in 3.

　　 The special effect of the fine grade iron pickaxe is a material of 5 or less. As long as the crit is hit, there is a certain chance that the special effect will be broken.

　　 Once triggered, the surrounding iron blocks will break like tofu. As long as you keep hitting it, let alone ten meters.

　　 is fifty or sixty meters, and Somo is confident that he will dig through it today!

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

　　 patted Moore on the back, looking at the latter's dazed expression, Su Mo laughed 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, the wall does not move except for the dust that falls down.

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

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

　　 One day's time currency can leave 72 picks 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 it slowly.

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

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

　　 This is a patient job. There is still a lot of time now, and Somo is not in a hurry. When he gets tired, he sits and rests, drinking saliva and eating dry food.

　　 After a break, it was another intensive work.

　　 "I thought it was only about ten meters long, but now it looks like this iron gate is 20 meters thick, so it's worthy of being a fellow man!"

　　 Seeing that after having spent three days of time and currency knocking out a full eleven-meter-long passage, the iron gate still looks endless. While admiring him, Somo has a basic understanding of the seventeenth level.

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

　　 I went back this time, not to mention anything else. After I went to the New World, I directly upgraded the materials of the underground refuge, and the entrance door was also increased to 20 meters!

　　 After another two or three hours, he opened the panel and found that after only twelve hours were left, Somo did not rest. He directly took out the Shanhai scroll card to recover his strength and continued to dig forward.

　　 In ancient times, there was a foolish old man who moved the mountain.

　　 Somo chiseled the door today.

　　 Numerous pieces of broken iron were dug out, and then Oreo pushed a self-made cart and fell into the courtyard.

　　 The old mother Doudou, but saw the Oreo of the same kind, has been lying next to him and talking non-stop.

　　 A relic that is extremely dangerous in the eyes of others, but in Somo's place, it has become a labor convention of a different kind.

　　 kept digging, whenever a critical strike was triggered, Somo waved on the iron gate beside him.

　　 The repetitive mechanical labor for more than ten hours is extremely laborious.

　　 Fortunately, Somo, who has lived in the wasteland for a month, has now endurance is not what it used to be, and he just survived.

　　咣!

　　 hum...

　　 was another skillful crit with a pickaxe hitting him, but this time, Somo's face was already gray and black, finally showing a smile.

　　 The iron gate finally has a sound!

　　 There is a sound, which means that the thickness has been reduced to within three to five meters. It only takes an hour or so to excavate, and this channel can be opened!

　　 With a goal, Somo only felt that there was a steady flow of power coming from all sides of his body, and his silent brain seemed to be injected into a Wang Huoquan.

　　, squatting halfway, the speed of the iron pick in Somo's hand suddenly increased, and sparks even appeared on the deformed iron block.

　　咚!

　　咚!

　　咚!

　　 One pick after another, the continuous iron filings fell off the iron door, and they were dug out by Moore with both hands, leaving Somo with the most space for digging.

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

　　 Finally, there was a crashing sound when the ruins were still six hours away.

Door...

　　 collapsed!

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

　　 Despite countless joys in his heart, looking at the depths of the dark room, Somo took a cautious rest for half an hour. After ensuring that his mental and physical conditions were restored to his heyday, he called the Tibetan Mastiff Doudou.

　　 "Wait to get inside, be careful, if there is danger, return in time!"

　　 Touched the head of the silly dog, and looked at its well-behaved appearance, Sumo's body was slightly bent, and he was ready 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, that would give Somo a hundred courage, and dare not use the mysterious side technology that hardens the future.

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

　　 I have been used to the darkness for a long time, and this sudden light made Somo close his eyes involuntarily.

　　 But just as Somo had just reacted before he had time to retreat, a thick male voice rang out in the refuge.

　　 "Welcome to 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 seems to have endless charm. At the first moment it sounded, Somo could not help but stop ~www.novelmt.com~Human?

　　No, this is Ma Fei?

　　 This is Ma Fei, the mayor of Liangfang Town?

　　 With curiosity, Somo tried to stick his head out of the iron gate, and then Somo saw the most shocking scene from the earth to the present:

　　On the second floor, there are not only high-end desktop computers that have been thinking about, but also piled up in the corner like debris.

　　 is a transparent tube with a diameter of one meter, densely spread on the ground like blood vessels, conveying water-like energy that has already been faintly blue.

　　 At the end of the line of sight, there is a whole wall made up of small robots that I have seen before.

　　Different from the previous construction machinery, these little people don't have anything on their hands, they seem to be in a dormant state, letting energy hit them, exuding a mysterious phenomenon like water ripples.

　　 All of this did not attract Somo's attention.

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

　　 This thing is not unfamiliar to Somo, and I have just seen it in a dream recently and have been greedy in a dream.

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