The Secret Records of the Green Crow: A Feng Shui Master’s Detective Notes The story centers on Shen Yan, heir to a lineage of feng shui masters. After living in seclusion for years, he receives an urgent distress letter from Zhou Mingyuan, an old friend of his grandfather, and travels to investigate the paranormal occurrences at the haunted mansion located at No. 17 Old Pagoda Tree Alley in Luocheng. The mansion has been plagued by a series of bizarre hanging deaths, which the police have ruled as a spree of suicides—yet these cases conceal eerie traces of a manipulated feng shui layout. Armed with the Qingwu Pei (Green Crow Pendant) and The Secret Records of the Green Crow passed down by his grandfather, Shen Yan uncovers the feng shui mystery of the mansion known as the “Yin Dragon Uprising”. He is haunted by vengeful spirits and further uncovers a conspiracy masterminded by Zhao Kun, an escaped convict. As his investigation deepens, he finds The Supplement to the Secret Records of the Green Crow, and learns of the hidden puppeteer Xuanfeng’s ambition: to destroy Luocheng’s feng shui with a yin fiend array and summon the Yin Dragon. From the haunted mansion by the Luo River to the ancient tombs in Mang Mountain, Shen Yan combines traditional feng shui secrets with criminal investigation and deduction. While unraveling layers of eerie mysteries, he guards the secrets left by his grandfather and thwarts the spread of the evil conspiracy. Blending suspenseful detective work with traditional feng shui culture, the work creates a gloomy and eerie atmosphere with a plot full of twists and turns.

At the beginning, the sixteen-year-old Gu Zhen lurked in the Black Bone Mountains, waiting for an opportunity to hunt down a low-ranking cultivator from the Azure Cloud Sect. This orphan had been abandoned at an orphanage since childhood and became a prisoner of an assassin organization at the age of ten. After undergoing the "kill or be killed" devilish training, he killed his master and went into exile, making a living by assassination. His target this time was a cultivator at the late stage of the Body Tempering Realm, whose cultivation base was higher than Gu Zhen's at the early stage of the Body Tempering Realm. However, he firmly believed that assassination skills and the grasp of weaknesses were far more superior.
