Standing in front of the carousel, the first thing he asked her was not "Hello", but "Have you noticed the speed?"
She is the youngest trace examiner in the technical department. She is used to hiding behind the microscope and letting the evidence speak for herself. He is the leader of the serious crime team, gloomy and taciturn, like a knife that has been tempered repeatedly - sharp, but full of cracks. Their first collaboration was a corpse tied to a wooden horse in an abandoned amusement park, with colorful candies stuffed in its mouth, bows tied around its wrists, and rose petals spread underneath. The murderer used a fairy tale to kill people, and Qi Ze understood the fairy tale - because he himself was a child who climbed out of the ruins of the fairy tale.
Five cases, five volumes of truth. "Blood Fairy Tale" reveals the revenge of an abducted child twenty years later; "Man in the Mirror" digs out the identity laundering industry chain under the plastic surgery hospital; there are seven abducted children in the "basement", and when Qi Ze stepped into the cage, his hands were shaking - he recognized the room where he was imprisoned twenty years ago. The case progresses layer by layer, and all clues ultimately point to the same name: a man codenamed "Doctor", a criminal psychology genius who was exiled from academia, and the only high-ranking person who has never seen his true face during Qi Ze's three years of undercover work.
What Jiang Yu didn't know was that three years ago, she found a set of fibers on a set of physical evidence that everyone judged to be "worthless". That report saved the life of an undercover police officer. That undercover agent is called Qi Ze.
"You saved me," he said, "three years ago. Now, it's my turn to protect you."
"No," she shook her head, "we're together."
Two people climbed out of the abyss and stood side by side on the edge of the abyss. The roots are entangled, supporting each other, and growing toward the light together.
Concept: Trauma is not a shackle, but a coordinate to identify the abyss. Two people who climbed out of the darkness did not choose to become the darkness, but chose to be each other's beacon.
