In the future world, memories are no longer private, but digital codes that can be repaired. Shen Yuan, the top "quantum memory restorer", has the rare talent of insight into the deep code of memory. He originally thought he was just helping clients retrieve their lost past, but during his repairs again and again, he came across cold and precise "trace of memory erasure." These traces are not accidents, but carefully planned plots! As the clues deepened, Shen Yuan discovered that the amnesiacs were not alone. They were all victims of secret human experiments by a technology giant called "Deep Blue". The giants try to control the social elite and even the entire world by manipulating memory.
However, it is not easy to repair memories. Deep in those erased memories, there are often huge traumas that can destroy the client. On the way to reveal the truth, Shen Yuan not only has to deal with the powerful forces of "Deep Blue", but also faces the ethical torture brought about by repairing memory: let the clients live in the "happy lie", or uncover the cruel truth, even if the cost is to tear their souls apart? What's even weirder is that Shen Yuan himself also has a blank memory, which seems to be inextricably linked to this experiment. When the partially awakened amnesiacs formed a resistance organization, Shen Yuan found himself in the center of the whirlpool. He must retrieve his past in order to completely expose the evil of "Deep Blue" and protect human memory and freedom!
