Every murder is an abyss of human nature.
Every scene hides the soul of the murderer.
Lu Chen is the youngest criminal profiler in the city bureau.
He is not good at words, but he can reconstruct the full picture of the murderer from a drop of blood, a footprint, and a slight expression.
There is no clairvoyance and no reliance on metaphysics.
Using only the criminal mind as an edge, he cuts through the lies and goes straight to the darkest parts of people's hearts.
Calm, paranoid, and to the point.
No matter how meticulous, cold-blooded or good at disguise the murderer is.
In his eyes, all actions have motives;
All sins have their traces.
He stared into the abyss and used his heart as a blade to cut away the evil spirits in the darkness of the world.
