Ling Xiao woke up in the doomsday wasteland, his memory was like a torn holographic screen, leaving only one name: Qi Jin. He followed the bloodstains and debris, picking up the fragments of human consciousness that had been dismembered—the remnants of civilization that had been erased by the "Purification Plan." Every memory hides crazy experiments, whispers of betrayal, and a voice that is always waiting for him in the dark. When Ling Xiao's right hand grew mechanical nerves, and when Qi Jin's pupils showed inhuman codes, they realized that they were not survivors, but abandoned experimental subjects, and each other was the only key to restarting humanity.
