Incriminating Puzzle

On the borderline between sin and justice, evidence is the only light. Chen Yuan, captain of the Municipal Criminal Investigation Detachment, has not solved the case of his sister's disappearance for ten years. This case has become an unhealable scar in his career and life. When an unknown female corpse broke the tranquility of the moat, a mysterious snowflake tattoo, and a blood-stained old cotton shoe, he and his teammates were involved in a huge criminal network that spanned campuses, mining areas, and borders. From mutilated limbs on the river to gunfire in mining areas, from the ashes of ancestral halls to cross-country pursuits of murderers, Chen Yuan and his team not only pursue the truth of the present in every fight against evil, but also get closer to the cruel past that has been dusted by time. When all the clues come together, they discover that the real devil often wears the most respectable clothes.
