Doomsday Convenience Store: All Customers Come from Seven Years in the Future

A convenience store that is about to close down will receive survivors from seven years later every midnight. Customers pay without money, leaving only a receipt for the future. On the small ticket were written the impending disaster, the list of the missing, and the death toll. The shop owner Jiang Hui must use ordinary goods and upgraded shelves to rewrite the ending before the disaster actually occurs.
