When urban young man Lin Feng woke up, he found that he had accidentally traveled to the dark and treacherous world of the dead, and was unreasonably recruited as a "ghost guide." After the thrilling and hilarious adaptation to the underworld for the first time, Lin Feng met the cold and shrewd trainee judge Su Xiaoming, the cunning and humorous old fritter Gou Chen, and the lively and kind little goblin Bai Xiaoyao. During the adventurous journey of the underworld's intrigues and crises, the foursome went from hunting down escaped evil spirits to uncovering the secrets of the underworld for thousands of years. They solved crises and gradually grew up, creating their own strange legend. During this period, there were both humorous and free-spirited daily souls, and cooperation in the form of deceiving others at the expense of one's life, as well as relaxed philosophical thoughts on the meaning of death and life choices. In the end, they worked together with wisdom and courage to smash Judge Cui's "absolute order" conspiracy and rejuvenate the underworld. The story brings a long undead adventure about death, growth, friendship and choice with climaxes of adventure and layers of humor.
