In a world swept by the "grey rot" nano-plague, humans are hiding behind high walls. Gu Chuanze, a low-level scavenger, broke into the ruins of the old world in order to survive, but accidentally awakened a sleeping military artificial intelligence "Prometheus". This AI is not only the only hope to cure the plague, but also contains the power to destroy the world. Double-hunted by the iron-fisted forces within the barrier and the mysterious organization that coveted AI, Gu Chuanze was forced to embark on the road of escape with this dangerous "ally". He must struggle to survive in the wasteland of the apocalypse, uncover the shocking conspiracy behind the plague, and ultimately decide the fate of mankind.
