When the apocalypse came, Lin Jin awakened the only "Mechanical Queen" power that could control metals and circuits, and built a formidable steel city in the ruins. But her elite ex-husband Zhou Ze, who had abandoned her for Bai Yueguang, had become an ordinary person without any special powers. He held his dying daughter and knelt down outside her castle begging for mercy. Lin Jin made a cold deal: sign a slave contract and go to the radiation zone to find parts for her in exchange for medicine. From then on, the once aloof CEO became the most humble scavenger slave. In the blood and fire of the wasteland, he tried his best to repay his past betrayal and gradually uncovered the shocking truth behind the conspiracy. This is not a story about forgiveness, but a legend about mastery, atonement, and redefining what "humanity" and "civilization" are on the ruins of the apocalypse.
