A living person delivers a secret + serial murders + a game of life and death 22-year-old Ah Xian became the only living employee at Huangquan Express Station, specializing in delivering "obsession packages" that dead people cannot send. An abandoned baby carton dripping with blood, a red dance shoe that eats a human leg, an old thing that cries in the middle of the night... Every express delivery is a game of truth that costs one's life. In order to find out the tragedy of her family's annihilation, she traveled between the Yin and Yang realms, uncovering the layers of disguised horror in people's hearts. "I am Ah Xian. Regardless of whether you are a human or a ghost, you must sign for this express delivery from hell."
