(This is a setting I've always wanted to see. Since no one has written it, I have to make my own pitfalls. I'm a complete newcomer. I apologize for everything.)
Forensic doctor Lin Jichen of the First Criminal Investigation Brigade of S City woke up one day and found that he was in the body of his archrival Song Yixing, the captain of the First Criminal Investigation Brigade of S City.
Lin Jichen: "???".
From then on, the medical examiner became the police, and the police became the medical examiner.
We don't distinguish each other, we all love each other the most.
