On a rainy night in the mausoleum, corpses floated to the surface of the river. A fatal incision, traces of deliberate erasure, and plaster powder left provocatively revealed the prelude to a series of highly intelligent serial killings.
Gu Lin, the criminal investigation captain, is cold and fierce, covered in hot sweat and smoke, and is the bravest hunter in the dark night.
The cold forensic doctor Shen Zhiyu, dressed in white and holding a sword, dissects corpses to find the truth. He is the only blade that can reveal the truth from death.
One charges into the battle and arrests the murderer with iron and blood; the other dissects silently and breaks the situation with professionalism.
The deceased hides his secrets, and the murderer hides his edge. The two work side by side in the blood and darkness, from floating corpses to secret room murders, from low-level gangsters to upper-class celebrities, step by step, they tear open the old sins of ten years ago.
The murderer uses killing as his art and the police as his chess, pressing forward step by step.
Gu Lin and Shen Zhiyu, using their hearts as a contract and their blades as shields, vowed to drag the devil hiding in the shadows into the sunshine in a tense confrontation and tacit understanding.
Winter has arrived, and murders are happening one after another.
Only you and I can pierce the night with the same sword.
Intention: Only you and I can pierce the night with the same sword.
