Chen Xin was unsure whether Li Wensheng had exchanged for diesel, but after making one more oxygen generator, his materials finally ran out. The remaining six group members who needed an oxygen generator would only be able to get one after he obtained new supplies from Qin Lan.
Knowing this, the other six group members naturally couldn't hold back. In such a situation, waiting even one more day could increase their chances of encountering danger.
But gathering materials was not an easy task.
Among the materials Chen Xin needed to make the oxygen generator, glass was the easiest to obtain. After all, if one didn't mind broken glass, it was everywhere now.
As for pipes, it wasn't too difficult either. By dismantling apartments where no one lived, it was possible to gather enough of them.
However, vacuum pumps and grow lights were much harder to collect. Two group members had spare grow lights, but no one had extra vacuum pumps.
