In order to save his seriously ill sister Ling Shuang, Ling Chen, a memory restorer in the Diying District, took on a dangerous job and was accidentally involved in the secrets of the "Yongyi Group".
Nightingale from the resistance organization "Dream Pickers" appeared and used "Life Memory Crystal" as bait to persuade Ling Chen to cooperate in stealing the group's core "Source Core". The two established trust during their initial cooperation and disguised their identities to sneak into the upper-class area.
Ling Chen discovered that the "Life Memory Crystal" was a lie, and trust was broken. At the same time, the villain Thorne offers him an olive branch, leaving him in a moral dilemma of betrayal or not.
Ling Chen pretended to cooperate with Thorne, but actually planned to use the final showdown between the two parties to sneak into the center of the "Source Core". He discovered that the "source core" is a living body composed of countless memories, and the price of saving his sister is to obliterate another soul.
5. **Ending**: Ling Chen gave up destroying or trading, and chose to free all imprisoned memories. The torrent of memories destroyed Thorne's rule and plunged Huicheng into chaos and rebirth. His sister's condition is stable, and he and Nightingale become desperate mandarin ducks, but they also become the founders of a new era. Thorne's consciousness turned into a digital ghost, paving the way for the sequel.
