Ye Lin, who traveled to a parallel world, was transferred from medical school to police academy under the threat of the system. He finally graduated after receiving five disciplinary penalties. He caught a wanted criminal within a few days of reporting. He joined the criminal police team from a police station and solved countless cases.

The first half of the book has a relatively fast pace, while the latter half focuses on criminal investigations and solving cases, so the pace slows down. Please understand. If you don't like the earlier chapters, you can skip directly to the later cases: 1. Chapters 82-119: The Serial Case; 2. Chapters 142-191: The Qiangteng Group Case; 3. Chapter 192: The Beginning of Zhao Dashan's Story; 4. Chapters 219-255: The Bride Case; 5. Chapters 280-300: The Lanyuan Community Murder Case; and later on, there's the Rural Girl's Missing Case and the Mao Xiaolin Case.
