Lin Ye, a 23-year-old compulsive stockpiler, senses something uncanny stirring in the world and starts frantically hoarding supplies. At a supermarket, he runs into Shen Yan, a 25-year-old spirit guide. A vermilion invitation bearing the words “When a hundred ghosts roam, the bearer survives” binds together two people who otherwise would have had nothing to do with each other. From a starving ghost knocking on thin air in an old apartment building, to bizarre poisonous plants nourished by resentment, to a darkwood coffin in a basement containing a century-old ghost, they face seven terrifying nights side by side, using their stockpiles as shields and talismans as spears. Beneath this battle between humans and ghosts lie the spirit guide’s sect secrets, as well as an obsession that transcends life and death. The ultimate purpose of stockpiling was never simply to save oneself, but to join forces with those who matter and preserve a glimmer of hope.
