Transformed into a dandy in an ancient town of the Republic of China, Shen Jingchen was bound to the [Villain Solving System] - his mission was to steal the destiny of his younger brother to solve crimes and prevent him from becoming a detective.
In the mountain god's murder case, he stole the key dagger but left traces of the real murderer; in the serial killings in Shanghai, he forged evidence but secretly passed on information.
The system wants him to be the villain, but he always "makes a mistake" at the last moment and delivers the truth.
Until his younger brother grabbed him by the collar and said, "Brother, do you act like you're helping me every time you cheat me?"
Shen Jingchen raised his eyebrows and smiled: "Silly brother, if you are not a villain, how can you force out the centuries-old chess game behind the scenes?"
The scheming brother × the genius and upright brother join forces to perform the middle game of a top crime bureau that spans the ages.
