In Xinhai, a city soaked in eternal rain and neon, memory is no longer private property, but a commodity that can be read, tampered with and traded. The giant enterprise "Yongshi Technology" used false happiness and a customized past to build an invisible "mental cage" for the city.
Lin Ye, a memory weaver who lives in seclusion in the "Abyss Zone" at the bottom of the city, is a legend in this gray area. He was cynical and only sold his skills in reading other people's souls for money, until a mysterious woman codenamed "Echo" came to his door. She comes with an impossible mission: to retrieve a completely destroyed memory.
This dangerous business dragged Lin Ye into the center of a huge whirlpool. Every memory fragment uncovered points to a concealed taboo experiment - "8049". In order to pursue the truth, he must fight against the ruthless purgers of "Eternal Time Technology", sneak into the heavily guarded sky fortress, and even face his own dusty past.
When the boundary between reality and fiction is completely blurred, and when the fate of the entire city hangs on a thread, Lin Ye must make a choice: continue to be a surviving bystander, or ignite a fire that can burn down the entire false world? Because he discovered that the erased memory was not only related to a woman's identity, but also contained the key to liberating or destroying everyone.
