Lin Mo is the night shift clerk at the "Hao Lai Lai" convenience store. On the day I joined the company, my boss only told me one thing: Don't open the door of the innermost freezer from three to four in the morning. It wasn't until that rainy night that a woman wearing Hanfu walked into the store, pointed to the freezer and said, "I want a pack of cinnabar, two stacks of yellow paper, and three sticks of rhino horn incense." Lin Mo discovered that this freezer was connected to another world.
