Feng Qinghe is the youngest commander of the Seventh Legion in the cyber era. He stepped on the air, and his consciousness was forcibly pulled into another time and space by his mentor, and he possessed the body of a high school girl accused of murder.
There is no smoke in this world, but there is a dirtier battlefield - Homecoming uses consciousness transfer technology to cultivate "receptor bodies" in batches, predators resell the data of time travellers, and they pretend to cooperate in traceability but actually monitor everything.
She opened her eyes from the interrogation room, used military tactics to track down the gangsters, and followed the clues to find out her anonymous cyber colleagues: special forces deliverymen, hackers in the financial circle, and field doctors in the mountains.
Surrounded by three parties, she forms a reverse team; her mentor persuades her to surrender, and she confronts her about the truth about the Ark Project.
From the hunted prey to the commander playing chess, she exposes the lie of "civilization continuation", turns the algorithm of consciousness into a bargaining chip, and seeks justice for all the bodies that have been robbed of their bodies in the gap between the journey back, the origin, and the predators.
——In this game, the time traveler is not a chess piece, only a game-breaker.
