When game designer Chen Mo accidentally deleted the design files of the ancestral secret room, a real-life escape invitation suddenly popped up on the computer screen - he and e-sports player Jiang Yao stepped into the secret room of an ancient house known as "impossible to pass", only to find that the hands of the wall clock were flying counterclockwise. The eyes of the wax figure of the maid in the first level of the "Bronze Mirror Mystery" were actually their lost childhood photos. What's even more terrifying is that the last words of the secret room designer who disappeared ten years ago were played on Jiang Yao's gaming headset: "Every time a level is broken, a memory of reality will be erased." When Chen Mo cracked the "abacus code", he discovered that the arrangement of abacus beads was actually his own unreleased game code, and what seeped out from the ceiling of the secret room was not water, but paper dust from his deleted design draft. When the moonlight in the seventh secret room shone on the overlapping shadows of the two people, they were shocked to realize that the designer of this escape game was using a time paradox to trap them into a new secret room mechanism - and the only way out was to personally delete all memories of each other's existence.
