The nuclear conflict triggered by the energy crisis resulted in a nuclear winter, forcing the remaining humans to take refuge in underground shelters. However, the resources available in these underground reserves are ultimately finite. To facilitate a swift return to the surface, a fully immersive game known as "Wasteland Survival Code" was mandated in all underground shelters. This game perfectly simulates everything that could occur on the surface, including radiation, hunger, and monsters. Players may encounter various lethal dangers. Each individual is permitted only three chances to be resurrected in the game. Once these resurrection chances are depleted, the intelligent main control system of the refuge will automatically sever all supplies to the player in reality, including food, water, and even oxygen. "Hello, this is player 9527, how can I sell this power armor?" The text reflects the apocalyptic wasteland style of the online game, with the game mechanics inspired by the radiation series from B company.
