Doomsday Bunker Upgrade

　　The same is true for other refuges. There are always things that you do not have, and I have things you do not. The existence of transactions and exchanges is the key to everyone's survival.

　　 It's just that Chen Xin got on the way of the SWAT team and could change from the SWAT team to more and more diverse items, so he didn't exchange supplies with other shelters.

　　 But now, now that he knows that helping others improve their living conditions can also earn survival points, Chen Xin naturally will not let go of the opportunity to communicate with other shelters.

During the routine communication time in the evening, Chen Xin first raised the issue of oxygen again. When he told Mo Qingyan before, he also notified other group friends at the same time, so Chen Xin raised it again at this time. Others naturally They also responded.

　　 "Fortunately, the writer reminded you of this. Before, I almost went out to search for supplies and didn't bring oxygen cylinders."

　　 "But even if I know this, there is no good solution, right? My family relies solely on the vegetables in the greenhouse to provide oxygen for photosynthesis, and now I don't even dare to turn off the light."

　　 "I heard that the government seems to have prepared oxygen generators at the official refuge, so now the city government is moving the population of small refuges to several large refuges. Are we also..."

　　 The group friend did not finish speaking, but his meaning was clearly expressed.

　　 If you can't survive, go to the official shelter.

　　 This is not an unacceptable or last resort choice. Several companions who could not survive have already chosen this path before. At this moment, it is quite logical for someone to put forward the same idea.

For Chen Xin, this was naturally the effect he wanted, so he hurriedly said, "I have a solution for the oxygen problem! I can make a simple oxygen generator. I have already traded it to Dragon Niang. If necessary, I can do it for you."

　　 "Writer, can you make an oxygen generator?!"

　　 "Really? I want one if you can do it as a writer!"

　　 "I want one too! Writer, what trading conditions do you need?"

　　 "With the words of the author, you will be my half-brother from today!"

　　 "Writer, what materials do you need to make an oxygen generator?"

　　 Chen Xin's words immediately caused a strong response. After all, for these survivors, being able to obtain an oxygen concentrator will undoubtedly help them survive in this end of the world.

　　 Although there is still a way to go to the official refuge, but you can live in a comfortable private refuge, who wants to go to the official refuge and struggle to survive?

　　 Before the end, they did not know what the conditions of the refuges built by the state were. Although the conditions provided by the state were not bad, they did not want to live in official refuges if they had a choice.

　　 Although everyone didn't say anything, but thanks to the blessings of so many doomsday movies and television works before the disaster, everyone knows the gloom of people's hearts in the last days.

　　 In a sense, the more people there are, the more likely it is to have problems in this end time.

　　 At first glance, this seems to be in contradiction with unity and cooperation to live better, but in fact the two do not conflict.

　　 When there are few people, it is mainly faced with threats from the external environment, while when there are many people, it is mainly because of internal conflicts.

　　 In the face of threats from the external environment, if there are too few survivors or there are only one or two people, then they can do very little.

　　 Apart from anything else, it is difficult for a person to build a strong refuge. If there are enough manpower, one can even send someone to collect supplies while building the refuge.

　　 But there are too many people. Everyone has their own ideas. It's okay if there are few people. You can discuss it.

　　 But there are more people, so naturally there are more thoughts. It is impossible to make most people think about the same thing, think in one place, and use strength in one place. On the contrary, more people are more dangerous than fewer people.

Therefore, at the beginning of the end of the world, when Chen Xin and the others discussed building a shelter, they actually came up with the greatest chance of survival, and the most reliable and appropriate method was actually to establish a community-like existence, bringing everyone together to help A small team has a reasonable division of labor, unites and cooperates, and faces the threats of the apocalypse.

　　 However, it is a pity that unlike the Federation, Yan Nation can sell abandoned missile silos and be converted into refuges by the rich.

　　 This plan of theirs was abolished from the beginning, and they could only build private shelters for each family.

　　 Although private shelters are more comfortable to live in than official large-scale shelters, it is obvious that private shelters are still lacking in terms of supporting infrastructure.

　　 Chen Xin didn't think about what he wanted to replace the oxygen concentrator, because for him, by giving the oxygen concentrator to others, his own survival point was his biggest gain.

　　 But obviously it is impossible for him to tell others that he doesn't want anything and give them an oxygen generator for nothing.

　　The story of Sheng Mi En fighting Mi Chou, but the ancient wisdom of Yan Country since ancient times.

"If you make an oxygen concentrator, UU Reading www.uukanshu.com mainly needs glass, a vacuum pump and a fill light. In terms of materials, I still have it here, so don’t worry." Chen Xin did not intend to ask others to provide materials. , But did not intend to give it away for nothing: "As for what to change, it depends on what you have. I will change it if I need it. I can't really make everyone suffocated."

　　 "Don't worry, you will definitely not suffer from the writer. I still have a few fresh fish. Do you want to eat fish, the writer?"

　　 "A few fish want to change the oxygen concentrator, are you too stingy? Writer, did you buy that SUV in my store? Now the environment is so bad, let me take care of it for you!"

　　 "The weather is getting colder, writer, do you need a heater? I have a spare heater."

　　 As soon as Chen Xin's voice fell, everyone immediately talked about their exchange terms, and wanted to impress Chen Xin and asked him to make himself an oxygen generator.

　　 After all, even if Chen Xin has the ability to make oxygen generators, he is alone, and the production efficiency is definitely not high. With so many people, one machine, if Chen Xin does it slowly, someone will definitely get it first.

　　No one wants to fall behind in this kind of life and death matters.

　　 Chen Xin can only feel helpless and funny about this, but he hasn't seen this lively scene for a long time.

　　 After the end, he is only one person most of the time. At this time, this lively atmosphere makes him feel a little more lifelike, and makes him feel that he is not living alone.

　　 But after listening to the various exchange materials reported by everyone, Chen Xin heard what interests him.

　　 "I exchanged a medical kit with you, the author. There are various commonly used drugs, medical supplies, and a set of simple surgical instruments, which are enough to deal with various common diseases and injuries."
