Bizarre murders have occurred one after another in Jiangcheng. The victims died in strange ways, and the scene is full of unexplainable and strange traces. Jiang Ce, a master tactician who is good at meticulous deduction and layout, was ordered to investigate the case. His partner turned out to be an incompatible enemy - Su Ye, known as the "Valkyrie". Su Ye's fighting prowess and fierce behavior are incompatible with Jiang Ce's step-by-step approach. The two went head-to-head, but were forced to work together to go deep into the dark corners of the city to solve unsolved cases shrouded in supernatural shadows. The provocations of local gangsters, the conspiracy behind the scenes of the ruthless family, the drunken heart-to-heart conversations in the tavern late at night... As the investigation deepens, they discover that there are more terrifying secrets hidden behind the murder, and the smell of gunpowder between them also quietly fills the air with a different flavor.
