Chen Mo, who was once an archaeological genius and now an ordinary courier, thought he would live an ordinary life carrying the secrets of the past. Until the brother was poisoned by a strange poison due to exploring an ancient tomb, and a mysterious package designated to be sent to "Dragon King Mountain" forcibly pulled him back to that bizarre world. In order to save people, he had to take the hamster "Gray Master" who accidentally became a spirit and had a talent for treasure hunting as his partner. In the name of delivering express, he broke into an ecological ancient tomb guarded by animal spirits after the founding of the People's Republic of China. Dealing with the fox fairy's magic, the bear's great power, and the willow fairy's poison, Chen Mo gradually discovered that the true value of this tomb was far from treasure, and the truth of the "accident" that led to his withdrawal was far more shocking than imagined. This is a desperate journey using modern logistics thinking to crack an ancient mechanism. It is also a new choice about guardianship, brothers and the meaning of life.
