In Lincheng, memories can be extracted, traded, and even cleared. Silence is a top "memory scavenger". He wanders through the deepest consciousness of others, erasing those painful or dangerous fragments in exchange for generous rewards and numbing his own blank past. During an unusual commission, he accidentally broke into a bloody memory that did not belong to the client, and saw a man who looked exactly like himself. This discovery was like a bomb dropped into the deep sea, completely shattering his peaceful life. In order to pursue the truth, Silence has to embark on a dangerous path and sneak into the darkest corners of the city, which are built from memories. He will discover that every forgotten secret is connected to a conspiracy that can subvert the entire world, and he himself is the center of this conspiracy storm.
