There is a secret circulating in Jiangyu University: at twelve o'clock in the night, if you say your wish to the mobile game "Mirror World", you will receive a test from "God".
Lin Che, a sophomore, is just curious, but she is involved in a death game - if she wins, she will get clues; if she loses, the real person will be "forgotten".
When her classmates and game friends disappeared one after another, and no one even remembered that they existed, Lin Che discovered that the game designer "Mirror" actually used the file number of his mother's disappearance eleven years ago.
Five levels of levels, five tampered memories. When the whole city thought he was a madman, Lin Che saw the "mirror" in the final secret room - it was himself who should have died eleven years ago.
