When a folklorist who believes in science meets a cynical "magic stick" singer, the two are forced to work together to investigate the strange happenings in the ancient town, but gradually uncover the fate and debt that have entangled each other for two generations.
· Shen Mo (attack): 26 years old. On the surface, he is a young folklorist who is supremely rational, but in fact he is a descendant of the "Soul Crosser" who can see souls. The heart is closed due to the shadow of childhood, and the temperament is cold and alienated.
· Xie Wuwang (Shou): 24 years old. A top-notch singer-songwriter, known for his deviance. His true identity is the "Seal Keeper" who uses music to suppress evil spirits. He seems cynical, but in fact he bears a heavy fate.
