In an abandoned old house on a rainy night, a thief died suddenly and mysteriously. There were no traces of a fight at the scene, only a "heart-piercing evil" Feng Shui formation that had been tampered with.
Shen Yan, a young Feng Shui master who made a living by relying on ancestral feng shui skills, was dragged to the scene by the criminal police team, half-coaxed and half-deceived. He just wanted to take care of his errands, but unexpectedly discovered that this murder was inextricably linked to his grandfather's mysterious death thirty years ago.
On one side is the criminal police captain who uses scientific logic to solve cases, and on the other side is the "magic consultant" who relies on yin and yang and the five elements to decide the matter. In the confrontations of unsolved cases, Shen Yan used ink fountains, copper coins, and compasses to solve the Feng Shui puzzle set by the murderer; in the process of reasoning, he gradually uncovered the truth of the old family case.
When criminal investigation methods meet the secrets of Feng Shui, and when modern crimes involve ancient secrets, Shen Yan must not only solve the murder in front of him, but also fight against the evil spirits hidden in the yin and yang realms. This is a Feng Shui master's investigative notebook, and it is also a journey of chasing a murderer spanning thirty years.
