Gu Luosheng, the youngest Jindan monk of the Qingcheng Sect, was ordered by his master to go down the mountain to investigate the serial murder case in Yong'an City. Thirteen people in the city died suddenly and mysteriously, with bleeding from their seven orifices. Behind the scenes, the Nether Sect, which had been dormant for eight years, was actually implicated. This cult, which practices evil arts with the souls of living people, is using the Blood Lotus Curse to pollute living beings, and is trying to use forty-nine pure Yang children to refine the Yin Yang Pill that can instantly improve a hundred years of cultivation.
While following clues, Gu Luosheng met the mysterious woman Shen Guichun. She carries a revolving lantern with her clothes embroidered with the iconic purple lotus of the Netherworld Sect. She knows the secrets of the cult very well, and her skills are ruthless but she hides her compassion. From suspicion to companionship, the two broke the Blood Lotus Curse under an old locust tree, formed an alliance with Marquis Jingwu in Chengdu Mansion, and finally went straight to the Ten Thousand Buddhas Summit of Mount Emei, the headquarters of the Nether Sect.
When the last oil lamp on the bloody altar was about to be extinguished and the cult leader Ye Jingfeng's magic was about to succeed, Gu Luosheng was shocked to realize that the cinnabar mark exposed on Shen Guixi's sleeves actually coincided with the girl who was saved on a snowy night in Qingcheng Mountain twelve years ago. And behind the conspiracy of the Nether Sect, there seems to be an even older curse hidden - the true purpose of the Yin Yang Pill and the fateful bond between the two are all laid in the dissipating clouds and mist of Mount Emei.
The prelude to the showdown between good and evil has begun. The fleeing leader and the unfinished blood feud will push them towards a more treacherous world. Where the figures of Qingcheng Taoist robes and white revolving lanterns intersect, it is the game between Tao and demons, and even more, the redemption that spans life and death.
