Twenty years ago, Chen Xuan, a Taoist priest of the Sanqing Temple on Zhongnan Mountain, saved an infant named Su Nan during a massacre. Su Nan possessed the once-in-a-thousand-years Nine Yang Sacred Physique, and a cult wanted to refine him into a Rakshasa Ghost Servant. To protect his disciple, Chen Xuan took a blood curse upon himself. Eighteen years later, his life force was spent. After coming down from the mountain, Su Nan made the Half-Immortal Pavilion fortune-telling shop his base. He made a living driving out evil spirits and telling fortunes through trickery and deceit (struck through), while investigating Qin Han, the real culprit behind his family’s slaughter. But he unexpectedly became entangled in the fates of five extraordinary women, beginning a roguish immortal’s life of “catching ghosts by day and warming beds by night.” A top-tier starlet sobs over a late-night video call, claiming she’s been haunted; a beautiful police detective points a gun at him and demands his help with a case. Su Nan discovers that every woman who comes near him has a destiny that aligns with the yin-yang and five elements.
Only when a witch from southern Xinjiang uses a mother-child gu to take the lives of two of his wives does Su Nan realize that the massacre from eighteen years ago was never truly over. The Yin-Yang Mirror reveals his master’s lingering soul, which tells him a shocking secret: the so-called curse is actually a marriage contract meant to reverse yin and yang, and all five wives are orphans from the massacre carried out by the black-clad men years ago. When thunder magic splits open the altar in southern Xinjiang, he finally understands the verse in the mirror: pure yang is no calamity; the mortal world is the true path of cultivation.
