Wish Contest, My Ability Is to Roll Back

Without warning, without source, without any physical trace, the Wish Contest came to the minds of all living beings around the world at the same moment. There is no organizer, no announcer, and no traceable existence. There is only a mechanical voice that is neither sad nor happy, neither male nor female, almost whispering in the void, penetrating all time, space and consciousness, cold and permanent: "Participate in the event and compete for points. The person at the top can realize any wish - no boundaries, no price, and everything." The competition uses the world as a chessboard, splitting up the real space and generating countless independent arenas, secret copies, taboo levels, and unknown areas. The rules of the space are distorted at any time, the scenes are randomly refreshed, and the tasks have no logic. The contestants are forced in, unable to refuse, unable to exit, unable to escape, and can only struggle to survive in the unknown fear. The real order in the arena is completely stripped away. There is no law, no morality, and no common sense. All actions are tacitly allowed. Humanity has completely collapsed under the temptation of unknown fears and ultimate desires. Killing, betrayal, sacrifice, and alliances are all normal. The entire world has become an absurd and bloody survival hunting ground controlled by unknown beings. No one knows why the competition exists, no one knows where the points go, no one knows the price of realizing a wish, everything is an unsolvable mystery. Points and Elimination Rules You can get wish points by completing weird tasks, solving unknown puzzles, seizing the secret treasures in the arena, and eliminating other contestants. There is no resurrection mechanism in the arena, and there is no chance of a comeback. One death is complete annihilation, and even memory and existence will be cleared from the arena.
