It takes place during the ''Ta-li'' of and follows the tale of a young man named ''Ts’ui'' who enlists the aide of ''Mo-lê'', his negrito slave, to help free his beloved who was forced to join the harem of a court official. At midnight, Mo-lê kills the guard dogs around the compound and carries Ts’ui on his back while easily jumping to the tops of walls and bounding from roof to roof. With the lovers reunited, Mo-lê leaps over ten tall walls with both of them on his back. Ts’ui and his beloved are able to live happily together in peace because the official believes she was kidnapped by and did not want to make trouble for himself by pursuing them. However, two years later, one of the official’s attendants sees the girl in the city and reports this. The official arrests Ts’ui and, once he hears the entire story, sends men to capture the negrito slave. But Mo-lê escapes with his dagger and flies over the city walls to escape apprehension. He is seen over ten years later selling medicine in the city, not having aged a single day.
Mo-lê’s gravity defying abilities and agelessness suggests the fictional character is a practitioner of esoteric life-prolonging exercises akin to Chinese immortals. According to a tale attributed to the Taoist adept Ge Hong, some hunters in the Zhongnan Mountains saw a naked man whose body was covered in black hair. Whenever they tried to capture him he “leapt over gullies and valleys as if in flight, and so could not be overtaken." After finally ambushing the man, the hunters learned it was in fact a 200 plus year old woman who had learned the arts of immortality from an old man in the forest.
