{Overhead Star Yuan 2187, "Port City" is an interstellar hub, half of it is a cybernetic block with flashing neon lights, and the other half is a gray area with surging undercurrents. Lu Chen, a former interstellar security team member, lost his teammates due to a bizarre mission. After removing his armor and returning home, he made a living by repairing old mechas. He originally wanted to stay away from conflicts, but when he took an order, he was accidentally involved in a series of "ghost signal" cases - the victims were all related to the "Zero Project" ten years ago. Without the blessing of superpowers, Lu Chen could only rely on his experience to dismantle the mecha wreckage and trace the data fragments. In the cracks between the police force, gangs, and interstellar consortia, he gradually uncovered the secrets of human experimentation behind the plan, and also pieced together the truth about the "sacrifice" of his teammates back then. }
