I traveled to a parallel world and became a police academy graduate.

When Xu Lin received his assigned work unit, he looked completely bewildered.

He, a prospective criminal investigator who graduated with top marks in criminal investigation, was assigned to the traffic police team. What does that mean?

So you won't let me do criminal investigation, huh?

That's easy, I, as a traffic cop, can also take over the work of criminal investigators.

On his first day at work, he arrested seven habitual thieves and one kidnapper and murderer.

The next day, a B-level agent was arrested.

On the third day, the mastermind behind a shocking case that had been hidden for 10 years was uncovered.

Day 4...

Traffic police captain: "Damn it, we're traffic police, why are you sending people to the criminal investigation department every day?"

Chief: "Who? Who sent Xu Lin to the traffic police station? Step forward! Investigate thoroughly, and get him dismissed from his post!"

A legend circulates among criminals: "You can go anywhere, except Jiangyun City. If you go there, you'll definitely get caught!"

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.

In 2017, a mining disaster tore apart families. Four years later, everyone connected to the disaster is linked by a serial killer known as the "Survivor's Gamble." Among them are detectives, journalists, wealthy second-generations, nurses, students, and delinquent teenagers... Rookie detective Peng Chuyan, inheriting his father's police rank, single-handedly faces a series of social crises: cyberbullying, school violence, domestic violence, Chinese-style parenting, workplace pressures, cheap rumor-mongering, apathetic spectators, animal cruelty, and unscrupulous media influence. Peng Chuyan's story unfolds in our daily lives, touching us all.

One after another, horrific and strange cases.

One after another, tortuous and bizarre tales.

Is it witchcraft, the supernatural, or pseudoscience?

Life and death, good or evil, they sometimes hinge on a single thought.

While the case may eventually be cracked,

how thoroughly can we understand the human heart?
