In an ordinary city, thousands of houses are brightly lit, and the delivery boy Zhang Tian who walks through the streets hides an unknown Taoist inheritance.
Others deliver food just to meet deadlines and earn errand fees. When he delivers food, he encounters ghosts, encounters evil spirits, and wastes souls along the way.
The strange orders in the old house late at night, the cold and evil atmosphere in the deserted alleys, the haunting supernatural things in the community...
He will always be there to take orders for strange houses that others avoid; he will deal with the yin and yang disasters that ordinary people cannot resolve with the raising of his hand.
Riding an electric bike through the city's fireworks, delivering food and earning a living while at the same time calming down the yin and yang, crossing over ghosts and ghosts, and bringing peace to all directions.
The way to make a living in the world is to make a living, and the integrity of the body is determined by yin and yang. I am just a delivery boy, and I am just trying to get rid of the evil spirits in the world!
