He Yuchi is recognized by the police as a "precision instrument", rational, cold, and severely lacking in emotion.
Xie Heng is the "mad dog" that the criminal investigation team avoids. He is violent, dangerous, and a high-functioning mental abnormality.
Three years ago, a miscarriage of justice caused the two to part ways and form a deadly feud.
Three years later, a series of "doll bride" cases suddenly appeared in the city. He Yuchi was forced to leave the mountain, and Xie Heng became his personal "shackles."
Xie Heng regarded him as a hypocritical elite and pressed forward step by step: "Counsellor He, your heart is beating wildly. Do you also want to kill someone?"
He Yuchi regarded him as an example of someone who was out of control, and said coldly and restrainedly: "Captain Xie, stay away from me, you are making too much noise."
It wasn't until they resonated mentally again and again in a pool of blood that they discovered that each other was the only "medicine" that could suppress the other's madness.
The burnt barcode on the back of Xie Heng's neck hides a secret that could subvert the entire city;
Behind He Yuchi's tampered profile report was a silent exchange of lives three years ago.
When reason becomes a shackles, only by embracing madness can we reach the truth.
"Xie Heng, I am your tranquilizer."
"He Yuchi, you are my accomplice."
Concept: Whether you are forced to see all cruelty or cut off feelings in order to survive, it is pathological. The real "healing" is not to eliminate symptoms, but to learn to find the balance point of one's own perception of the world in a chaotic world.
