Elite detective Lin Feng took over the serial murder case and found that every scene was a "teaching" carefully arranged by the murderer. What's even more frightening is that the killer Han Ye took the initiative to become his consultant in solving the case.
"Welcome to the real world, good cop."
As the investigation deepened, Lin Feng found himself involved in a psychological experiment that lasted for decades, and every choice he made was recorded and analyzed. And Han Ye, this elegant and crazy criminal psychology professor, is both his mentor and his most dangerous opponent.

A psychological game about justice and evil has officially begun.
