Thirty-five-year-old Chen Zihao, a laid-off delivery rider, takes orders under a sun hot enough to fry an egg, desperate to buy his parents in the countryside a new refrigerator. One day, while delivering an order to the eighteenth floor, he takes an accidental fall and somehow "falls" straight into the legendary underworld! He thinks his life is over, but discovers that the underworld is in desperate need of a "living delivery rider" who can bring a taste of the mortal world. He delivers hot rice noodles to lonely ghosts longing for mortal food, coffee to judges who stay up all night hearing cases, and even a delivery to the King of Hell's thousand-year banquet... (To be continued!) Armed with the delivery skills he honed in the world of the living, where "one late delivery and a bad review means you're done for," Chen Zihao begins his "death-defying delivery" career between the worlds of the living and the dead. As he handles all kinds of bizarre ghost orders (such as delivering bubble tea to Granny Meng, made with a "not-bitter" version of her memory-erasing soup), he searches for clues that might take him home and unexpectedly crosses paths with the mysterious underworld figure Ling Yuan. Through deliveries blending comedy and danger, he uncovers the underworld's little-known secrets of everyday life and finds himself in a heartwarming, fantastical romance that spans life and death.
