Sun Mo, a recently retired scout, accidentally obtained the "Justice Trial System". The system gives him super reasoning ability and crisis prediction, but he faces a moral choice every time he performs a task: Should he abide by the rules or fight violence with violence? In order to lurk into the city to investigate a serial disappearance case, he followed the system prompts and had a flash marriage with the mysterious woman Lin Ruoxi. However, behind Lin Ruoxi there is the secret of the warlord force "Blood Shadow Society". Sun Mo discovered that every case he took over was related to the warlord's interest chain, and every mission in the system tested his bottom line. When the boundaries of justice are blurred, and when rules become the protective umbrella of evil forces, this cautious and iron-blooded retired soldier chooses to fight violence with violence. However, every time he "fights violence with violence," the system will deduct his personality points. Once they reach zero, he will completely become black. Sun Mo must find a balance between systematic punishment and justice execution, and Lin Ruoxi's true identity gradually emerges...
