In July and a half of 1995, young Lu Chen was involved in the case of the old locust tree's innocent soul due to his "soul-departing pattern", and was discovered by Zhang Huai, a disciple of Sanqingguan. The hanged ghost Li Qiulan he saw was actually the innocent soul buried under the locust tree by the clan leader's soul-suppressing nail. After using Lu Chen's mouth to express his grievances, the grievances were resolved. Lu Chen was also accepted as a disciple by Zhang Huaiqing because of his talent, and he was about to embark on the path of practicing Sanqing Guan.
The story is set in Jianghuai countryside, and revolves around the special physique of "being able to see ghostly things" and the Taoist tenet of "transferring people but not ghosts", unfolding a series of supernatural cases: the soul-calming nail at the bottom of the old locust tree, the bronze bell that chimes in the ancestral hall, the mysterious locust leaves that appear with the whereabouts of the master and the apprentice... What is gradually revealed during the exorcism process is not only the grievances of the deceased, but also the greed, selfishness and prejudice in the hearts of living people that are more terrifying than ghosts. The game between Taoism and people's hearts, the entanglement between wronged souls and the truth, let's see how the master and apprentice use the locust leaves as a guide to solve the mystery of the world between the Yin and Yang worlds.
