I Said to Deduce the Truth, Not Play Turtle Soup!

The muscles in a person's face can form ten thousand different expressions.

An expression that slips out unconsciously can reveal what you're thinking.

Ke Bei, a PhD in the psychology of facial expressions, transmigrated to another parallel world.

He also became a detective.

A year after arriving in this world, he successfully activated the "Turtle Soup" System.

While everyone else was still trying to solve a case,

Ke Bei had often already found the culprit.

Baffling, complicated cases with no clues.

A poisonous tiger that devoured its own young.

A fearsome demon king who slaughtered an entire village.

One seemingly unsolvable case after another, including cold cases.

With the System's help, Ke Bei found the true culprit in every one.

Wherever Ke Bei goes, no criminal can escape detection.
