Chen Yan, a criminal investigation intern, has been burdened with the trauma of his family being swallowed up by a strange shadow since he was a child. He has been diagnosed with schizophrenia. His only obsession is to find his sister who has been missing for ten years.
The dark red runes of an eye-gouging murder case led him to accidentally enter the "Zhenyin Pass" in the mysterious town of the Republic of China - there is no day and night here, and taboos are like iron laws. Opening the window at midnight or turning around at three times will lead to death. The evil slaves are rampant, and the haunted house in the ghost city is full of copies of death.
From then on, he was forced to jump wildly between reality and mystery: he was suddenly chased by a strange creature in the interrogation room, and he suddenly woke up in a mental hospital bed deep in the murderous house.
Using criminal investigation thinking to break weird taboos, using spiritual media to communicate with the dead souls of Yin and Yang, with Yin jade in hand and Yin Qi protecting his body, Chen Yan stepped on the boundary between life and death step by step.
The coffin-opening ceremony of the Wangyou Society attempts to tear apart the two realms, the sacrificial conspiracy of the town guards hides murderous intentions, the mysterious shadow of the Yinsi Pavilion involves the truth behind the disappearance of the sister, and even the police station in reality hides the collusion of evil spirits.
Being slandered, wanted, and in a desperate situation, Chen Yan became more and more courageous the more he fought: "Use madness to overcome deceit, use truth to destroy falsehoods, both worlds are hunting grounds. Anyone who stops me from finding my sister will be killed by gods and ghosts!"
