"Director, look over there, there are some newly built factories over there." Zhang Yaxuan took Liu Bi and General Lu to visit the base on Xiadao, the area of the military base on Xiadao is very large, and the three of them rode bicycles around here.

There are a lot of bicycles in Xiadao, even now they are the same, you can see a lot of bicycles everywhere, the base of Xiadao is much larger than the shelter, there are tens of thousands of people living here, there are not only factories but also some farmland, many people are working.

Moreover, the Xiadao base also has the same point system as the Vault, but theirs is still different from the one in the Vault.

"If only our vault had such a large area." Liu Bi is also very envious of the area of the Xiadao base, what the shelter lacks most now is the area, the area of the shelter is very good, and all the places that can be used are fully utilized.

Even the sixth basement floor where Liu Beep lives is covered with various machines, and Liu Beep now wants to expand the previous floors, but because of the problem of materials, there has been no way, in fact, Liu Beep found that the most limiting thing about the development of the Vault now is the construction materials.

With building materials, it can be expanded, whether it is to expand the previous floor or to build a new floor, it can speed up the development of the shelter, Liu Bi also wants to build a factory, now that there are more people with materials, the weapons are obviously insufficient, and it is impossible to meet Zhang Yaxuan alone.

Liu Beep was visiting, but Huang Nan and they came to the house where Lin Yibo went before, there are a lot of instruments in the house, and the power here is the strongest in the entire base, the entire base can be powered off but not here.

This is the research institute of the Xiadao base, and it is also the production place of mutant potions, and the very simple large machine in the hall is the first generation of mutant potion production machines, and when it is first manufactured, it takes five crystals to make a bottle of potions.

However, in later research, the second generation was built, which is now used, and this mainframe was no longer useful, and was placed in the hall for decoration.

After Huang Nan took them into the research institute, he kept going inside, and when he came to the innermost room, Huang Nan stopped and knocked on the door.

The door was quickly opened, and it was Lin Yibo, Huang Nan and the others, who had come here earlier, walked in, and an old man wearing a researcher's white coat was typing something on the computer.

"Sit down, Wei Lao is using a computer to analyze the possibilities." Lin Yibo beckoned a few people to sit down and wait on the side for a while.

After about ten minutes, Wei Lao stopped.

"How's Wei Lao's condition?" Lin Yibo saw that Wei Lao had stopped, so he immediately stood up.

"We analyzed it and then discussed it preliminarily, you said that the mutant is human, and we think it is possible, but now it is just some speculation, we don't have anything to study now, so there is no way to make a small conclusion." Wei Lao shook his head, although these things are possible, but there is no evidence to prove, and there is nothing to study with ordinary zombie crystals, but the crystals of mutants are too rare to be studied by them.

The crystallization of mutants can make mutants mutate 100% of their abilities, and they haven't studied the crystallization of mutants, but they haven't studied anything, after all, they didn't have any knowledge of crystallization at that time.

"Anyway, it's kind of some progress, isn't it."

"Hehehe, what kind of progress is this, and it is not progress if you don't find the cause of this catastrophe." Wei Lao shook his head, he was in his seventies, if he used the mutation potion, he might not be able to continue working, and the only thought now was to find the cause of the catastrophe on this side, and then find a solution to the apocalypse.

"Elder Wei doesn't have to be like this, you have already made a lot of contributions." Huang Nan is right, Wei Lao has also made contributions to all mankind, after all, the current use of the potion making machine and the previous first generation were all developed by Wei Lao.

"Who are you?" Zhang Yaxuan returned to the room where they were resting, and suddenly found that there was an extra person in the living room of the room, and Zhang Yaxuan immediately became alert.

"The old way?" However, the man ignored Zhang Yaxuan at all, but directly skipped Zhang Yaxuan and ran in front of General Lu.

"Mayor Qin."

"Old Lu, I didn't expect you to be alive, great! That's great! Mayor Qin was very excited, although he wondered why General Lu had wrapped himself up, but it didn't hinder his excitement.

"Old road, or you can stay here." After seeing General Lu, Mayor Qin wanted to let General Lu stay, after all, he felt that the army base was much safer than the shelter.

"No thanks, Mayor Qin, but Lu Wen and they are all in the shelter." Of course, General Lu would not agree to stay here, not only because of General Lu's family, but also because of General Lu himself, he could hide in the shelter, but even if he was hiding here, he couldn't hide.

"Well, that's it, but at least we can be together now." Mayor Qin didn't say much, after all, General Lu has been busy all his life, and now he can be regarded as giving the family time to reunite.

Both of them were a little embarrassed, but fortunately, Mayor Qin left immediately.

Two days later, it was still dawn, but many vehicles in the parking lot of the base had already started, and many people were preparing there.

A lot of home-made explosives and mines were loaded into the car, Huang Nan as the commander this time, as well as Long Xiaolian and Zhou Wei, the two awakened people with their team members, Zhou Wei's special operations team also has his own team formation, which is the same as Long Xiaolian's.

"Let's go!" In Huang Nan's voice, everyone set off, and the surrounding soldiers immediately stopped and saluted the convoy, and Lin Yibo also came with a few people, but Lin Yibo didn't go, but those people brought by Lin Yibo, that is, those who did not belong to the army, were also recruited.

Those people also had their own cars, and they also got on the convoy and left, Lin Yibo looked at the distant convoy and could only salute, and then hoped in his heart that this time it would be smooth.

This time they went to the vicinity of a building in the area controlled by the zombies, during this period of time the zombies began to destroy on a large scale, according to the research of the staff officers, probably those zombies will come here today to destroy, their purpose is to carry out an ambush here.

There weren't actually too many zombies along the way, most of the zombies followed the large army, and they came to the ambush site smoothly.
