In 2045, the neon lights of Binhai City penetrated the mist, and a huge billboard of "Xinyi Technology" was reflected on the glass window of the hospital - "Memory transplantation, making forgetting a thing of the past." Neurologist Lin Zhou stood in the ward and looked at his sister Lin Xi on the hospital bed, but he only felt that this slogan was like a thorn.
A year ago, Lin Xi suffered an "accidental" car accident. When she woke up, she lost all her memories and could not even recognize her most familiar brother. The official medical treatment announced "permanent memory damage", but Lin Zhou discovered a clue that had been deleted repeatedly in the late-night forum: there were "non-compliant memory transplants" in the underground market, which could awaken memories that even cutting-edge instruments could not repair.
For the sake of his sister, Lin Zhou broke the medical practice rules he had adhered to for seven years for the first time and followed the encrypted address to find the "Grey Alley" - an alley hidden deep in the old city that sells memories for a living. Here, he met Chen Ye: a man carrying a black backpack and with traces of light blue memory extraction agent on his fingers. The other man opened his mouth to expose his weakness: "What you want is not 'repair', but 're-engraving' - but the re-engraved memory always carries the shadow of others."
