Shanhai Convenience Store

By day, it sells instant noodles and bottled water; by night, it sells between the yin and yang realms. After losing his job, Lu Chen inherits a convenience store on the verge of bankruptcy, thinking he can only scrape by. But unexpectedly, every midnight, the shelves refresh with goods from another world. Mythical beasts, yin gods and ghosts, wandering spirits and demons... They pay with merits, only to exchange for a lingering obsession. And Lu Chen's job is to guard this store. Open at midnight, no living customers allowed. — Description from novelcodex.org
