Solving the Case: I'm Serious

He was supposed to be an ordinary office worker, but he was accidentally killed by someone who jumped from a building, causing him to travel through time. He became a detective and obtained a super-super-super-super-deciding system. Let's see how he uses the super-super-dead system to solve various major cases and deter various criminals. Later, people commented on him: "As long as he is still here, all kinds of illegal and criminal activities will be greatly reduced or even eliminated!" I never joke about solving cases, I am serious about solving cases! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
