Chen Xin is just an ordinary person, indistinguishable from everyone else. He can cry, be afraid, feel dejected, and despair.
The only difference, perhaps, is that he got a bit luckier, having a system that can improve living conditions and serve as a cheat.
The system brought a chance for change, and change means a better future.
This is also why Chen Xin hasn't had an emotional breakdown before, because the system is like a carrot dangling in front of a donkey, allowing him to keep moving forward.
But a carrot is just a carrot, a temptation that can be seen but not necessarily reached.
Perhaps in the distant future, when Chen Xin upgrades his shelter to a sufficient level, he will live well and comfortably. But for now, he is still struggling in this apocalypse like everyone else.
The future might be beautiful and bright. Maybe the donkey can finally eat the carrot that tempted it all the way, but along the way, it has to endure the constant temptation of that carrot.
