After the camp function breaks through to the third level, the main structure of the reinforced concrete building is first opened in the structure, the same material, but because of the different proportions, it is no exaggeration to say that the concrete wall built by the camp system is more than twice as strong as the artificial construction in reality.

The maximum building of the camp has been directly increased to five floors, and the most surprising thing is that the function of the basement has been unlocked, and the current limit depth can only be two underground floors, and the range cannot exceed the maximum range of the camp.

This is invisibly equivalent to adding an additional underground camp to Chen Fei, which also makes Chen Fei shift the focus of the construction of the camp from the ground to the underground!

Compared to the ground, the underground area is obviously safer, whether it is facing zombies or facing survivor attacks, the basement is definitely a good place to hide, and Chen Fei has made a basement under each building, although the space is smaller, it can be used as an air-raid shelter in an emergency.

The initial focus of the construction of the entire underground area is mainly on the main building and warehouse of the camp, before Chen Fei only built a small part because of material problems, and now he has collected so many materials, Chen Fei can not only expand the area of the basement, but also further build the area of the second basement, as well as the underground passage connected with the warehouse and maintenance center.

This kind of huge project, if Chen Fei alone thinks hard and doesn't know what to do in the end, there are too many problems involved, including power system, exhaust ventilation system, drainage and water supply system, etc.....

It is only at this time that Chen Fei can think of the advantages of the system father, he just provides the direction of thinking about the design, and the camp will automatically generate the design of the building plan and some other supporting systems for him, what Chen Fei has to do is to choose.

As Chen Fei put more and more effort into it, the more Chen Fei looked forward to the effect of his camp when it was put into use.

The construction of the security zone is to first build the fence, and then build other building facilities within the high wall, which is a problem in the collection of materials, and it is also a problem in the construction of buildings.

Because of the lack of equipment, the construction of manpower will be more difficult, even if the vast majority of the survivors in the security are mobilized as labor, the progress of the construction is still unsatisfactory.

Chen Fei has an absolute advantage in this regard, from the collection of materials to the construction of buildings, if the materials can be supplied indefinitely, it is not impossible for Chen Fei to build a city in one day.

After this period of reconstruction and expansion, Chen Fei expanded the main building of the camp from a 10-meter square area to a length of 18 meters and a width of 15 meters, and the floors were also raised from three to four percent.

Among the two main problems of water and electricity, Chen Fei has barely solved the problem of electricity, and he has collected a lot of solar panels, which can basically cover the roof of the main building of the camp, and the general electricity can also be satisfied.

According to this progress, when Chen Fei found the location where he placed the camp, his camp definitely had the conditions to move in with his bags, and the arrangements were clear to ensure that everyone was satisfied.

......

He Guantao, Zhou Fa and Wu Hongbin loaded seeds and soybeans onto military trucks, sweating profusely.

"Lao He is now in October, why is the weather still so hot? I feel like I'm going to be a dry corpse."

Zhou Fa wiped the sweat from his forehead and looked up at the big sun above his head.

He Guantao didn't look up and rummage through the backpack he was carrying, but he still replied:

"Ah Fa, what did the eldest brother say? Use your brain!

How long has it been since this last day came, more than a month! It rained so much in more than a month, it's no wonder it's not hot! ”

Zhou Fa nodded lightly, paused, and continued:

"That's right, it's better to be smarter!"

He Guantao scoffed at Zhou Fa's stinky foot behavior:

"You can pull it! Together, we are not as good as the big brother, the fight is not as good as the big brother, and the brain is not as good as the big brother, I think the two of us, in addition to being able to repair cars, that is, being more handsome than the big brother can still be said....."

Wu Hongbin, who was passing by, twitched the corners of his mouth, and looked back at He Guantao and Zhou Fa in disbelief, thinking that he had auditory hallucinations.

After discovering the sincerity of these two people's faces, Wu Hongbin shook his head helplessly and muttered in a low voice:

"Alas.... It's a good two kids, but it's a stupid car repair......"

Partition.......

He Guantao took out a bottle of Coke from his backpack, drank half a bottle in one go, made a long gap with satisfaction, handed the remaining half bottle to Zhou Fa, and inadvertently looked up to see Chen Fei sitting cross-legged on the roof.

"Huh? Ah Fa, where do you say the eldest brother is doing? He Guantao leaned into Zhou Fa's ear and whispered.

Zhou Fa scratched his head and replied firmly without thinking:

"I don't know!"

"Holy! Guess what! He Guantao was speechless.

Zhou Fa pondered for a moment and frowned and said, "Uh....... Let's cultivate immortals! "Ambiguous 43

"Shhh........hh Cultivating immortals? Are you sure? ”

He Guantao did not question Zhou Fa's speculation, but felt that what Zhou Fa said was really reasonable.

"That's right! Isn't it all written like that, you see that the eldest brother sits so high just to attract the essence of heaven and earth, I guess that the eldest brother is now a master of the innate stage, and when he continues to cultivate, it will become the foundation building period, and then he will be a land immortal...."

He Guantao listened to it with half a doubt, he has been talking about evolutionaries and evolutionaries recently, to be honest, he and Zhou Fa really don't know what evolution does not evolve, or martial arts and immortal cultivation are more reliable.

He Guantao frowned and pondered for a moment, then looked up at Chen Fei who was sitting on the roof and whispered:

"Or let's beg the eldest brother and let him teach us a trick and a half, you see that the fat brother is very powerful now, he can kill mutant zombies alone, the scales and strength on his body, it must be the eldest brother who taught him the practice of refining the body!"

Zhou Fa was also convinced of this, and hurriedly asked, "What kind of body refining method is it?" So powerful! ”

"Hmm...... You see the fat guy has scales on his body, I guess..... What should it be called? Or the Divine Dragon Immortal Body! ”

Listening to the conversation between the two on the side, Wu Hongbin's expression became more and more exciting, his cheeks trembled, and the corners of his mouth kept pulling, he was really defeated by the brain circuit of this simple brain duo.

After getting along for a while, with Chen Fei and Wu Gang helping to popularize science, Wu Hongbin now understands a lot of things, including what mutated zombies and evolutionaries are, but they don't cultivate immortals!!

Chen Fei and Wu Gang are evolutionaries together, so their combat effectiveness is so violent, ordinary zombies can't get close at all, and when encountering mutant zombies, only they can evolve, or they use sniper rifles to shoot their heads.

"Huh? Brother Wu! What are these two guys talking about there? ”

Wu Gang asked with a smile as he passed by Wu Hongbin with a cauldron on his face.

"Uh...... They're guessing what kind of exercises you practice, and they'll become so powerful......"

Wu Gang smiled innocently and walked behind He Guantao and patted him on the shoulder:

"Hey, do you two want to know what kind of exercises I'm practicing?"

He Guantao and Zhou Fa chicks nodded vigorously like pecking rice, but Wu Gang smiled mysteriously and pointed to the wooden fence in the distance:

"You two, go and tear down some fences and come back to chop them for firewood, this game can only be better eaten if it is stewed in a big pot with firewood, as long as you two complete the task well, I will tell you the secret of my cultivation!"

"No problem, fat brother, just look at it!"

He Guantao slapped his chest on Bangbang, turned his head and went to the car to find a fire axe to chop those wooden fences.

After Wu Hongbin looked left and right to make sure that there was no one next to him, he leaned over to Wu Gang's side with an embarrassed face and asked in a low voice:

"Huh? Gangzi, what exercises do you really have? ”

Hehehe....

Wu Gang smiled and replied honestly:

"I lied to them, Brother Wu, you also believe it, there is no exercise, and you don't know what happened to me."

Wu Hongbin was speechless for a while, isn't this a simple duo playing with brains, and he also soaked him again.

"What are you going to do with them when they're done chopping firewood?"

"Hehehe....... You don't have to worry about this, when these two guys finish eating my stewed game, make sure they forget who they are, do you think they can still remember what I said? ”

After Wu Gang finished speaking, in the helpless eyes of the red pen, he walked to the temporary earthen stove with the cauldron, and only then did he notice that Zhao Xiaoping was gone!

"Xiaoping, Xiaoping, call Xiaoping!"

"Roger! Roger that! Fat man, I'm patrolling the perimeter, what's wrong? Is there a situation? ”

Hearing a voice response on the walkie-talkie, Wu Gang breathed a sigh of relief.

Since Brother Xiao Chen is obsessed with cultivating immortals, as a capable general and chef, he must work harder.

"It's okay, it's just to tell you not to go too far, too far away for fear that you won't be able to support each other in case of emergencies later!"

“OK！ I'll go back! ”
