Nanxia

Work introduction A series of murders on a rainy night broke the peace of the city, and former criminal investigation consultant Li Chuyu was forced to return to the scene of the crime. He was once labeled a "dangerous personality" because of his sharp criminal profiling ability. After lying dormant for many years, he was still able to capture the murderer's thinking trajectory from clues. Zeng Ruicheng, the criminal police captain who was ordered to take over the case, is recognized in the industry as the "Iron-faced King of Hell", with rigorous logic and decisive actions. A secret room murder case involving an old case forced the two to form a temporary partner. Li Chuyu is good at diving into the darkness to interpret the abyss of human nature, while Zeng Ruicheng insists on procedural justice to tear through the fog. The extreme contrast between personality and case handling methods creates fierce sparks during the investigation process. From the strange symbols in abandoned factories to the hidden grievances in wealthy houses, clues are intertwined, and the truth is hidden under layers of lies. They are not only rivals who refuse to give in to each other, but also the only comrades who can trust each other's back. As the investigation deepens, suspicions about the old cases that caused the estrangement between the two have surfaced, and the mastermind behind the serial murders is quietly pushing them into greater danger. When the dark side of human nature collides with the glimmer of justice, can this "old enemy partner" put aside their prejudices and uncover the deepest truth in the thrilling pursuit of the murderer?
