Chen Mo, who was born with yin and yang, was raised by his master in a Taoist temple in the mountains. He had no father or mother, and only an ancient jade pendant with the word "passion" engraved on it kept him close to him. This jade pendant was the only relic left to him by his parents. When he was eighteen years old, his master left a riddle before his death: "The city gate is open, yin and yang are wrong, and the twin lotuses are hiding in a poor place." In order to solve the mystery of his life experience, Chen Mo took a compass and talisman from the mist-shrouded Qingxuan Mountain into the neon-lit Linjiang City.
Underneath the prosperity of the city lies hidden dangers: celebrity night shots, evil spirits appearing in haunted old houses, and dead souls locked in the feng shui bureau of commercial buildings... Chen Mo uses Maoshan's secret skills to cross the worlds of Yin and Yang, but he is accidentally involved in the conspiracy of the mysterious organization "Xuanmen Society". When he discovers that the disappearance of his parents is closely related to the "Yin Yang Murder Case" thirty years ago, when his childhood sweetheart village beauty appears in the city streets in the form of a ghost, the ancient Yin Yang magic hidden in Yu Perry gradually awakens, and what he is about to face is a shocking secret that overturns the entire Xuanmen world...
