Deep suspense, extreme wits, complex human nature, and the fatal attraction that wanders on the edge of good and evil. The relationship between Lu Yin and Qin Mo is the real core of the story. They are not a simple confrontation between police and gangsters, but symbiotic souls torn apart by the same disaster and going to two extremes. One internalized pain becomes the "anchor" and the other externalized pain becomes the "knife". This setting is full of tragic beauty and dramatic tension.
