Doomsday Department Store: My Supplies Are Unlimited

Daily refresh: At zero o'clock, an "infinite supermarket" that overlaps with reality is only open to the protagonist, and the supplies are random (it may be ten thousand tons of rice, or it may be infinite toothpicks). Forced clearing: The "inventory" must be cleared by any means before 24:00 on the same day. If even one bottle of water is left behind, the system will shut down permanently. Value anchoring: The system will provide a "today's core product" (such as unlimited antibiotics). The distribution of this product will subtly affect the "difficulty" of the next day's world and the rarity of refreshed items.
