Core plot: When Lin Mo, a young criminal psychological portraitist, detects a series of perverted murders, he discovers that there is a manipulator named "Dark Eyes" behind the scenes. He is eventually revealed to be his adoptive father and mentor, Qin Ru, an authority in police psychology, and faces the ultimate choice of his own dark side.
**The Beginning (Prologue-Chapter 6):**
In the "Wedding Suffocation Case" on a rainy night, Lin Mo used his keen profile to identify and capture the murderer Wang Qiang, the warehouse manager. The strange sense of ritual at the crime scene, Wang Qiang's mention of "he was right" when he confessed, and the mysterious "eye-shaped symbol" in his book led to a provocative anonymous letter, revealing the existence of the "dark pupil". At the same time, the "Bleaching Offal Case" occurred, with completely different methods.
**Development (Chapter 7-18):**
Lin Mo successively solved the "bleaching case" (the surgeon Li Zhenhua was blackmailed and was instigated by the dark network to commit murder in the name of "purification") and the "live broadcast kidnapping case" (the unemployed young man Zhang Wei was manipulated into a "trial clown"). The styles of the cases are very different, but they all show traces of being "shaped": Li Zhenhua hinted at a "higher will", and Zhang Wei's associates offered up a "criminal script", all pointing to online "mentors". Lin Mo confirmed the "Dark Eye" control mode and was on the verge of mental collapse.
**Climax (Chapter 19-Chapter 27):**
The murderer of the "Living Sculpture Case" Zhou Fan (a down-and-out genius sculptor) directly provoked Lin Mo and identified Lin Mo as his "mentor's work" when he was arrested. Its computer data reveals the in-depth cultivation process of "Dark Pupil". Ghost in the police station leaked information
