He makes a living by stealing memories, but becomes a lamb to be slaughtered in other people's memories. In the "Mirror City", a futuristic city with distinct classes, Chen Mo is engaged in a special profession - the Forgotten Sampler. He can sneak into the consciousness of others, extract and carry painful memories, and buy inner peace for his clients. There is an ironclad rule in the industry: the memory of the same customer must not be sampled a third time. However, the appearance of the mysterious woman Lin Yin allowed Chen Mo to break his taboo. The third sampling is not the end, but the beginning of a sophisticated trap. Not only did he fail to strip away the client's memory, but he was reversely implanted into a strange "memory program" - the program actually contained his own long-forgotten childhood images. The peaceful life was completely shattered. In order to pursue the truth, Chen Mo was forced to go deep into the most chaotic bottom and the most strict top floor of Mirror City, only to find that he had been involved in a huge conspiracy that spanned decades. When he finally touched the core secret, what awaited him was a bullet accurately shot between the eyebrows.
Death became the beginning of his "rebirth". When he opened his eyes again, he found that he was actually parasitizing the body of the assassin - a rough and fierce gangster "Scarface". His consciousness, Lin Yin's programming, and Scarface's instincts all coexisted in this strange body. Now, he faces the enemy and walks in the enemy's camp. He must use the enemy's hands to investigate his case; use the identity of the murderer to uncover the deepest dark side of civilization. When memories can be tampered with and identities can be replaced——
Is he hunting the truth, or is he himself the sacrificial lamb of the truth...
