Xia Xiaowan, an ordinary college student, was addicted to the game "Collapse Star Railroad", but one night he traveled to a post-apocalyptic wasteland where civilization collapsed, and he died in the cruel ruins. After rebirth, Xia Xiaowan was surprised to find that her physical condition had been replaced by game data, and she became a special existence in the doomsday world, the 'Judge' - with the ability to control the weaknesses of mutant beasts, and the game's built-in wasteland survival simulation system, which can predict dangers, find resources and shelters. Her appearance attracted the curiosity and greed of many forces, especially the old human survivor organization and the mutant beast group in the wasteland. In the crises and conflicts one after another, Xia Xiaowan must make choices on the edge of morality, use the simulation system to avoid fatal traps, and at the same time recruit like-minded companions to jointly build a new shelter in the wasteland and explore the truth hidden in the post-apocalyptic world and the possibility of rebuilding her home.
