An old, dilapidated supermarket on the verge of bankruptcy. Cao Yiran thought he was taking over the business, but he didn't expect that he was taking over the door. Behind the door leads to the fairy world, selling goods and setting up stalls, and the days are becoming more and more prosperous. But there is a door behind the door, and there is a door behind the door. Behind one door stands an identical supermarket. That night when Lao Chen was dying, he put the silver nameplate into his hand: "Do you think you are opening a store?"
