Random Mission System of the Apocalypse

Ps: This article has a single female protagonist. One day, the end of the world really comes. There are zombies, mutant beasts, and people with ulterior motives. His parents are still alive and his family is not poor. Lin Xiaohua, who is not exactly the protagonist in the novel, actually got a system. In this post-apocalyptic world where you can't fight, have no brains, and the jungle is the strongest, you can only rely on the system to build your home.
