The world is shrouded in the disaster of "data erosion", and reality is forcibly gamified by the energy of another dimension, but it is full of fatal bugs. At midnight every Monday, the rules come and the doomsday forms are randomly switched: zombie frenzy, absolute zero, AI rebellion, cognitive distortion... Each hell lasts for six days. The seventh day is not a redemption, but a "data reset day" - the city is restored as before, monsters are refreshed, some dead are "resurrected" in the void, and the world is like a flashback. Only the memories and bound items of the survivors survive, accumulating scars and secrets in endless reincarnations. In the cracks of these chaotic rules, an "eternal supermarket" bound to an individual quietly appears. It is exempt from reset and becomes the only constant coordinate and hope in the drifting apocalypse.
