Crime Investigation: You Just Joined the Police Academy, and You're Sending a Professor to Prison?

Gu Chen transmigrates to a parallel world and becomes a freshman at Jiangcheng Police University.

The System awakens on the day he checks in.

[Ding! An extremely dangerous criminal is detected within a hundred meters. Identity: the criminal psychology professor at the lectern!]

So, under the gaze of the entire school, Gu Chen quietly takes out his handcuffs and walks up to the lectern.

“Professor, you wouldn’t want that locked-room murder from twenty years ago to come to light, would you?”

The whole school is stunned!

Veteran detective: “I told you to check in, and you just happened to solve a cold case that had stumped us for twenty years?”

Ice-cold CEO: “Gu Chen, if you help me catch the real killer who murdered my grandfather, I’ll sign the marriage agreement!”

From then on, the police force gains a “living King of Hell” whose name strikes terror into criminals.

You claim you’re a high-IQ criminal and left no evidence?

Gu Chen: “Under Locard’s Exchange Principle, every breath you exhale is evidence!”
