Deep in the Daxingan Mountains, there are vast forests and rolling snow ridges, hiding countless unknown secrets and taboos. Chen Yan, who lives in the shack of the Chen family, grew up with his grandfather who knew occult arts. He memorized many spells and formulas under the influence of his ears and eyes, but he was always dubious about these "knowledge of the elders". Until he was twenty years old, a boy from a neighboring village was haunted by a yellow fairy. His grandfather solved it with a gift, allowing him to see the mysteries of Xuan Shu with his own eyes, and he embarked on the road of inheritance.
From Huangxian's request for a title, evil in the ghost house, to ghost possession and feng shui breaking, Chen Yan followed his grandfather through the mountains and rivers of the Greater Khingan Mountains, using the ancient secrets and secrets in "The Secret Record of Mysterious Medicine" to resolve one evil incident after another for the mountain people. He identified external diseases and determined Feng Shui, used glutinous rice to drive away evil spirits, peach trees to ward off evil spirits, used compasses to determine acupoints, and talismans to channel spirits. He understood the essence of metaphysics through repeated practical operations.
Ten volumes record the local customs and mystical practices of Daxinganling: there are stories of rescuing children haunted by yellow immortals on a snowy night, stories of relocating tombs and changing the fortune of a house that has been haunted by evil spirits after the beginning of spring, cracking the strange ghost-possessed features of a wooden house in the mountains, and adjusting the layout of a village in a bad Feng Shui situation. Every case is in line with the reality of Daxinganling, and every secret technique has practical steps and basis. There are no ethereal fantasy settings, only down-to-earth folk wisdom and mystical inheritance.
Chen Yan gradually grew up in the process of protecting his neighbors, transforming from an ignorant boy into a calm and mysterious doctor. He always kept in mind his grandfather's teachings of "having a right mind, practicing diligently, and respecting nature."
