The private shelters are the same; there are always things you have that I don't, and things I have that you don't. Trading and exchanging are the keys to everyone's survival.
It's just that Chen Xin has connections with the SWAT team, allowing him to trade for more and a greater variety of supplies, so he hasn't needed to trade resources with other shelters.
But now, knowing that helping others improve their survival conditions can also earn survival points, Chen Xin naturally won't miss the opportunity to communicate with other shelters.
During the evening's routine communication time, Chen Xin first brought up the oxygen issue again. This was an issue he had informed Mo Qingyan about earlier, and he had simultaneously notified other group members, so as Chen Xin mentioned it again, others naturally responded.
"It's a good thing you reminded us, Writer. I almost suffered from oxygen deficiency because I went out searching for supplies without an oxygen tank."
