The protagonist Lin Tian is an ordinary white-collar worker. On the day of doomsday, the company was swamped by zombies and he almost died in the elevator. At a critical moment, he accidentally obtained a "doomsday apartment system" that overlapped with the real world. This apartment can not only isolate zombies, but also generate survival resources such as food and weapons. However, apartments must be rented to operate, and the "strength" of tenants directly determines the development of the apartment.
