Global catastrophe, ghosts are rampant. Zhou Mo, a former food delivery rider, has become the most scarce material delivery person in the apocalypse. When he saved a little ghost and automatically bound his phone to the "Difu Suda" APP, his style of painting completely changed. During the day, he delivers hope to the survivors' stronghold; at night, he delivers comfort to the wandering souls. He sent a suicide note to a fallen soldier, granted a wish for an obsessive old man, and even purchased the latest paper-bound mobile phone for a bull-headed horse face. With outstanding performance, his Yin De was cashed out. From then on, in the wasteland surrounded by demons, he relied on express delivery to provide a way to survive between the Yin and Yang worlds. He also became a gold medal commissioner on the performance list of the underworld, making both black and white jealous.
