Chen Mo was born with the ability to perceive both Yin and Yang, and was raised by his master in a mountain Taoist temple. He has no parents, only an ancient jade pendant engraved with the words “Rebirth,” the sole keepsake his parents left him. Before passing away when Chen Mo was eighteen, his master left him a riddle: “The city gates open, Yin and Yang are reversed, beneath the twin lotus lies a fallen soul.” To uncover the truth about his origins, Chen Mo takes his compass and talismans and leaves mist-shrouded Qingxuan Mountain for the neon-lit city of Linjiang.
Beneath the city’s glittering surface, danger lurks: a celebrity encounters evil spirits during a night shoot, a haunted old house reveals blood-written characters, and a feng shui formation in a commercial tower traps the souls of the dead... With his mastery of Maoshan arts, Chen Mo moves between the worlds of Yin and Yang, but unexpectedly becomes entangled in the schemes of a mysterious organization called the Xuanmen Society. When he discovers that his parents’ disappearance is closely linked to the “Yin-Yang Blood Case” of thirty years ago, and that the girl he grew up with, the village beauty, has appeared on city streets in the form of a ghost, the ancient arts of Yin and Yang hidden in his pendant begin to awaken. What awaits him is a shocking secret that could overturn the entire world of the mystic arts...
