Lin Shen, the former chief archive restorer of the City Archives, lives in an obsession that no one believes in.
Three years ago, her younger sister Lin Wan disappeared during the demolition of the old cotton mill. However, her parents, relatives, friends, household registration files, and neighbors on the street all insisted that Lin Shen never had a younger sister. Only in his absolute memory was his sister's appearance clearly engraved, and the last text message she sent before she disappeared: [Brother, they are deleting my existence, I am in the copy, don't believe in the rules].
In this city, every piece of black history that has been deliberately erased by power, capital, and time will be folded into a strange "reverberation copy": a newsstand that disappeared at four in the morning, a subway station that does not exist on the map, an abandoned shopping mall that has been closed for many years... The core rules of the copy are the sealing clauses that covered up the truth back then; those who violate the rules will be completely "sealed". Only by poking the narrative loopholes in the rules and restoring the buried truth can the situation be broken.
In order to find his sister, Lin Shen broke into one life and death dungeon after another, but the closer he got to the truth, the more horrifying he discovered: deep in each dungeon, there were handwritings he left three years ago; he was not a game-breaker who accidentally entered the game, but the first generation creator of this dungeon system.
When the reality of the entire city began to collapse, he finally understood: what he was looking for was never his missing sister, but the ultimate truth about the entire city that was sealed by his own hands.
