I Bound a Detective System and a Crime System

Working hard to build up my collection before starting the story!!! [Hello, Host. I am a detective System with proper training. Obeying the law and fighting crime are our professional principles. I hope our partnership will help you become a world-famous detective.] [Hello, Host. I am a criminal System that illegally smuggled itself in. Breaking the law and destroying justice are our principles. I hope our partnership will help you become a world-class criminal.] Two voices rang out in Qiao Lezhi's mind at the same time, and he suddenly understood why there was a silver bracelet around his wrist. "You were the last person General Qiao saw before he died, and you were also the last person mentioned in the terminal's final message. What do you have to say for yourself?" Even so, their eyes and attitude toward him made it clear that they had already decided he was the criminal. [Host, the detective System will earn you the trust of justice's allies. Just say you're innocent, and you can clear your name!] [Host, the criminal System will get you accepted by the villains. Just refuse to confess, and even if they know you're the culprit, they won't have any evidence!] The five judges on the tribunal all thought they must be crazy. Otherwise, why would they keep switching between thinking he was an innocent bystander caught up in things and thinking he was an assassin who had committed multiple murders? Then... They saw the person before them smile. "Could you get a mental health expert to examine me first? I think I'm mentally ill. There are two voices in my head egging me on to cause trouble." The judges: "..." After finally confirming that it wasn't a delusion caused by split personality, Qiao Lezhi, who now knew the Systems were real, sat in his cell and sulked. He had a clear understanding of his own terrible luck. If luck had levels, his would be an incurable E. If something as absurd as being bound to both a justice System and its dark, opposing System could happen to him, what could possibly be more ridiculous? After being found at crime scenes over and over again, even the Qiao family couldn't suppress a scandal that had spread across the stars. Under pressure, Qiao Lezhi was once again escorted to the tribunal. And then it hit him! If he wanted to rule the world, he had to become a combination of Moriarty and Sherlock Holmes! Detective System: [...] Criminal System: [...] How did they end up bound to an edgelord, of all people?! Theme: A sunny day
