Abandoned Son of the Police Force? I Brought Down the Entire Empire!

Because my theory was too radical, I was hidden by the police force and became an outcast. When the perfect secret room murder came and the Ace of Spades trial made the whole city panic, they could only pin their last hope on me! They thought it was just a serial murder, but I saw through the shocking conspiracy that spanned twenty years! They thought their opponents were powerful politicians, but I uncovered the "Ouroboros" of the transnational financial empire that controlled everything! Partner with the hot policewoman and join forces with the devil genius. From crime scenes to cross-border manhunts, from psychological profiling to financial wars, I, Qin Mingxuan, will use my brain to uncover the conspiracies of human nature and overthrow the entire dark empire! This is an ultimate showdown with human hearts as the chessboard and wisdom as the weapon. They have an empire, and I will overthrow it!
