Rules Abyss

The real world is being "eroded" by an indescribable force. This kind of erosion is not a doomsday-style destruction, but a silent covering - "abnormal areas" (i. E. Copies) will appear randomly in daily space, and those who enter must abide by specific rules to survive. Those who violate the rules will not be simply killed, but will be "rewritten": they will become part of the rules, lose their self-awareness, and become NPCs or monsters in the next instance. There is no "safe zone" in this world. The frequency of abnormal areas is accelerating and their scope is expanding. Human society maintains order on the surface, but everyone familiar with the matter knows: the countdown has begun.
