When Lin Wei was reborn from the mountain of corpses and sea of blood in the apocalypse three hours before the disaster struck, she thought she could reverse the tragic death of her companions with her foresight. The survival manual she released was like the wings of a butterfly, which not only attracted the iron-blooded commander Gu Yunshen who had never appeared in her previous life, but also pushed her into the center of the storm - she became the host chosen by the mysterious creation "Key", and this purple rain disaster sweeping the world was actually a civilization screening experiment carefully planned by a force called "Master".
From establishing order in the ruins to sneaking into the dystopian base "The Other Side" with a cruel contribution point system, Lin Wei formed a core team with the rational Gu Yunshen, the calm and reliable Lu Hanzhou, and the cunning and unruly Su Banxia, struggling to survive in the fierce game of humanity and efficiency. They finally discovered that the so-called "performance" and "contribution" were just steps leading to a grander conspiracy - the mastermind behind the scenes intended to upload all human consciousness to the virtual world and format reality. Driving a deep-sea assault boat, Lin Wei and her partners resolutely rush to the last forbidden city of mankind, "Ya City". There, she must use the wisdom brought by rebirth, the power given by the key, and the unreserved trust and love of her companions to challenge the supreme will that is trying to define the "perfect new humanity" and fight for the last hopeful future in the fragmented real world.
