You Solved a Murder Case on Your First Day at Work?

Shen Mo transmigrates to a parallel world and becomes a criminal police officer. After unexpectedly activating the Detective System, he embarks on an unbelievable path of crime solving:

On his first day at work, he casually cracks a staged suicide-by-fall case by the roadside.

He stops at a restaurant for a bowl of noodles and ends up exposing a serial killer who had evaded capture for ten years.

While traveling, he solves a dismemberment case at an abandoned quarry.

The experts scratch their heads. "This case is impossible to solve!"

Shen Mo calmly pulls out his handcuffs. "The suspect's in custody. Case closed."

The criminals collectively lose it. "It was a perfect crime! How did you figure it out? Are you cheating?"

There is no such thing as a perfect crime, only clues that no one can hide from his eyes.
