2032, Shanghai. Under the surface of the prosperous modern city, an evil spirit that has been dormant for hundreds of years is quietly resurrecting. Bizarre murders occurred one after another in the old city. The deceased all showed signs of chaos, with a cinnabar mark between their eyebrows and no trace of their souls.
Chen Shu, an ordinary young employee of the Ancient Book Restoration Institute, originally lived a peaceful life, but because of a broken manuscript and a Bagua compass left behind by his grandfather, he was involved in this Xuanmen catastrophe that spanned a hundred years. He gradually discovered that he was actually a "genuine Dunjia" born in the "Bingwu Year of the Horse" (2026), and he had the almost-extinct inheritance of the Qimen Dunjia lineage.
In order to uncover the truth and save himself, he had to follow his grandfather's clues and reopen the door to metaphysics. With the help of Lu Li, an antique shop owner who is both good and evil, and Bai Zhi, a policewoman with a mysterious life experience, he started from the cryptic words of "Song of the Fisherman on Smoke Waves" to the secret pictures of "Golden Letters and Jade Mirrors", and practiced step by step the three secret skills of "Qi Men", "Liu Ren" and "Tai Yi".
However, as the investigation deepens, an ancient evil sect named "Nine Nethers" emerges, and its goal is directly at the legendary "Seventy-two Bureaus of Disha". Chen Shu gradually understood that this was not only a confrontation between good and evil, but also a race against time - if all the evil spirits were unleashed, the world would become a purgatory.
From the spirit-binding net in the old house in Shencheng, to the ancient altar deep in the Zhongnan Mountains, from the Feng Shui Killing Game "White Tiger Holding the Corpse" to the "Blood Moon Soul-inducing Array" that reverses the yin and yang, Chen Shu was forced to face an ultimate choice in the process of protection and sacrifice: should he follow the way of heaven and "do nothing", or should he use a mortal body to practice the art of "defying heaven and changing his destiny"?
