On the surface, Wang Chen is an ordinary takeaway rider, but in fact he is proficient in spells, feng shui, and evil-fighting techniques. A new Happy Malatang opened in the city. The store owner secretly used lunch boxes and paper cups to set up traps to track down the food, absorbing the grievances of diners and killing passers-by. Many victims died mysteriously. During an accidental delivery, he rescued Lu Ci, the owner of a cold noodle stall who accidentally ate evil soup. He discovered that he had awakened the Heavenly Doctor's pupil after a car accident and could see evil black energy with the naked eye. The two work together to track down the evil behind the scenes, follow the clues of the disposable tableware supplier, decipher all kinds of shady arts, protect street vendors and office workers, step by step dig out the true identity of the evil cultivator hidden in the corners of the city, and clean up the resentment traps all over the city.
