She dissects truth, she hunts down lies. They are each other's only exception and the city's last line of defense. Until a corpse was engraved with the thirteenth lifeline dedicated to them.
There are twelve pairs of human ribs, which are symmetrical and complete, forming a cage to protect the heart.
Forensically, there is no thirteenth rib.
But Yan Jichu knew that there was something more secret than the ribs and more deadly than the heart——
That was the invisible lifeline between her and Shi Jin.
One builds walls with reason, and the other breaks them with intuition.
The day the wall fell, the murderer stood among them.
Concept: Criminal police and forensic doctors, one is chasing lies, the other is dissecting the truth. They do not settle cases by lynching, nor do they violate the rules out of hatred. Even in the face of the murderer of his mother and his father, he insists on using a frighteningly complete chain of evidence to bring the crime to justice - this is an insistence on "procedural justice" and the highest tribute to professional beliefs. The scar on Shi Jin's wrist, the appraisal certificate in Yan Jichu's safe - they have all been stared into the same abyss, and they all chose to walk back with a lamp to illuminate the abyss. This beam of light was called "self-destructive loneliness" before meeting each other, and it was called "going side by side" after meeting each other. In forensic medicine, there are twelve pairs of ribs, which protect the heart. But what really saves a heart from breaking is never the bones, but the presence of another person. That invisible "lifeline" is the confidence they give each other. It is the courage and tenderness of another person who still chooses to believe in him after he has gone through the darkest time.
