Jiang Yuan, a brilliant and enigmatic forensic expert, arrives at the Zhengguang District Criminal Investigation Branch with a reputation that precedes him—known for solving impossible cases through unparalleled scientific precision. While others rely on intuition or brute-force investigation, Jiang Yuan employs forensic botany, serology, and tool mark analysis with near-supernatural accuracy, leaving seasoned detectives stunned. Assigned to a cold murder case with minimal evidence, he transforms mundane crime scene fragments—pollen grains, blood patterns, fabric fibers—into irrefutable clues.

His unassuming demeanor and quiet confidence mask a mind that sees what others overlook, turning the sterile lab into a battlefield of silent evidence. As he navigates bureaucratic indifference and skeptical colleagues, Jiang Yuan’s methods begin to unravel deeper secrets hidden beneath the capital’s polished surface. With each autopsy and microscopic analysis, he inches closer to a conspiracy that reaches far beyond a single murder—and into the shadows of China’s forensic system itself.
