Yu Huanian traveled to a parallel world called "Rules and Ghost Stories" and participated in a cruel survival competition with 99 other "lucky people" who were selected. The rules of the game are extremely special. Participants can edit their own "powers" without any restrictions on their use, but the price is that everyone is under nationwide surveillance. Once the core activation condition, effect or form of the ability is guessed by the monitor, the ability will be deprived and the original owner will face direct obliteration.
