It's the same with other shelters, there are always some things that you have and I don't have, and trading and communicating with each other is the key to everyone's survival.

It's just that Chen Xin took the path of the SWAT team, and he could exchange more and richer types of things from the SWAT team, so he didn't exchange materials with other shelters.

But now, now that he knows that helping others improve their living conditions can also get survival points, Chen Xin naturally won't miss the opportunity to communicate with other shelters.

During the routine communication time in the evening, Chen Xin first brought up the issue of oxygen again, and when he told Mo Qingyan before, he had also notified other group friends at the same time, so at this time, Chen Xin mentioned it again, and others naturally responded.

"Fortunately, the writer reminded me of this, I almost ran out of oxygen because I didn't bring an oxygen cylinder when I went out to search for supplies."

"But even if you know about it, there's no good solution, right? My family relies on the plants in the greenhouse for photosynthesis to provide oxygen, and now I don't even dare to turn off the fill light. ”

"I've heard that the government seems to have oxygen concentrators on the official evacuation centers, so the city government is moving the population of the small shelters to several large shelters. Are we also ......?"

The group member didn't finish his words, but his meaning was clearly expressed.

If you can't hold on, go to an official shelter.

This is not an unacceptable or last resort choice, there have already been a few companions who can't make it through before, and it is only natural that someone would put forward the same idea at this moment.

For Chen Xin, this was naturally the effect he wanted, so he hurriedly said: "I have a solution to the problem of oxygen!" I can make a simple oxygen concentrator, and I have already traded one to Long Niang before, if you need it, I can help you make it. ”

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

"Really? Writer, if you can do it, I want one! ”

"I want one too! What trading conditions do you need for a writer? ”

"There is a writer who said this, from today onwards you will be my half-brother!"

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

Chen Xin's words immediately caused a strong reaction, after all, for the survivors, being able to get an oxygen concentrator can undoubtedly help them better survive in this apocalypse.

There is still an option to go to an official shelter, but who wants to go to an official shelter to survive if they can live comfortably in a private shelter?

Before the end of the world, they did not understand what the conditions of the shelter built by the state were, although the conditions provided by the state could not be considered bad, but if they had a choice, they did not want to live in the official shelter.

Although everyone didn't say it, thanks to so many apocalyptic film and television works before the disaster, everyone knows about the darkness of people's hearts in the last days.

In a sense, the more people there are, the more likely they are to have problems in these last days.

At first glance, this may seem contradictory to the idea that we can live better by working together, but in fact the two are not in conflict.

If there are few people, they mainly face the threat from the external environment, while if there are many people, they mainly face internal contradictions.

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

Not to mention, it is difficult for a person to build a strong shelter, and if there are enough people, they can even send people to collect supplies while building a shelter.

But there are many people and there are many people, everyone has their own ideas, and it is okay to have fewer people, everyone can discuss it.

However, if there are many people, there will naturally be many ideas, and it is impossible for most people to think about the same thing, thinking in one place and working hard in one place, and it is more dangerous for more people than for fewer people.

Therefore, at the beginning of the apocalypse, when Chen Xin and the others discussed the construction of a shelter, they actually came up with the greatest chance of survival, and the most reliable and suitable method was actually to establish an existence similar to a community, bringing everyone together, with a small team model of reasonable division of labor, unity and cooperation, to face the threat of the apocalyptic disaster together.

However, it is a pity that the Yan Country, unlike the Federation, can sell abandoned missile silos and be used by the rich to transform them into shelters.

Their plan was scrapped from the start, and they had to build a private shelter for each family.

Private shelters, on the other hand, are more comfortable to live in than large official shelters, but in terms of supporting infrastructure, it is clear that private shelters are still lacking.

Chen Xin didn't think about what he wanted to exchange for the oxygen concentrator, because for him, giving the oxygen concentrator to others and getting a survival point for himself was his biggest gain.

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

The story of Shengmien's fight against Mi is the ancient wisdom of the Yan Kingdom since ancient times.

"If you make an oxygen concentrator, you mainly need glass, a vacuum pump and a fill light, and I have the materials myself, so you don't have to worry." Chen Xin didn't plan to let others provide materials, but he didn't plan to give them away in vain: "As for what to exchange, it depends on what you have, if I can use it, I will change it, and I can't really suffocate everyone." ”

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

"A few fish want to change the oxygen concentrator, you're too stingy, aren't you? Writer: You bought that SUV in my shop, right? Now that the environment is so bad, I'll help you do a major maintenance! ”

"It's getting colder, do you need a heater there, writer?" I still have a spare heater here. ”

As soon as Chen Xin's words fell, everyone immediately talked about their quid pro quo, wanting to impress Chen Xin and ask him to make an oxygen concentrator for himself first.

After all, even if Chen Xin has the ability to manufacture oxygen concentrators, he is only one person, and the production efficiency is definitely not high.

In this kind of life-and-death matter, no one wants to be left behind.

Chen Xin could only feel helpless and amused by this, but he hadn't seen such a lively scene for a long time.

Most of the time after the apocalypse, he was alone, and this lively atmosphere made him feel a little more life, making him feel that he was not living alone.

However, among the various exchange materials reported by everyone, Chen Xin heard something that interested him.

"I used the medical kit to exchange with you, the writer, which contained all kinds of commonly used medicines, medical supplies, and a set of simple surgical instruments, which was enough to deal with all kinds of common illnesses and trauma."
