Selling Memories to Counterattack

He sold his memory for money, but bought back a perfect kill. In order to save his sister who suffered from a rare disease, brain scientist Lin Shen stepped into the memory black market and sold his most cherished childhood memories in desperation. The transaction was successful and he received the life-saving half a million. However, that night, the buyer of the memory - a top rich man - died mysteriously. What's even more terrifying is that the vision and pain of the deceased before death were "feedback" to Lin Shen's mind like a ghost. With his professional knowledge, he deciphered the evil coordinates encoded in the feedback memory, and was shocked to find that the memory he sold was actually a set of hidden instructions for a perfect crime. He is not the seller, but the "living weapon" unintentionally used by the murderer. At this time, a huge sum of money from an unknown source was deposited into his sister's medical account, as if a pair of invisible eyes were mocking him in the dark. The sister who was unconscious on the hospital bed began to unconsciously draw the fatal symbol in her memory. The man behind the scenes slowly surfaced, and it was an old friend who had a deep connection with him. The other party is quietly screening "tool men" through memory trading to execute a huge conspiracy to subvert reality. When Lin Shen discovers that the next locked "perfect container" is his sister, he must bet his own brain as the final battlefield. In this ultimate game about memory and reality, is what he sells the insignificant past, or all the proof of his status as a "person"?
