Secret Identity Exposed: The Intern Is a Max-Level Detective

Does the perfect crime really exist?

The killer wipes away fingerprints, cleans up the blood, destroys the weapon, and fabricates an alibi, convinced they've left no trace.

But in Lin Han's eyes, every crime leaves evidence.

Once an experienced criminal investigation captain, he died and transmigrated to a parallel world, where he became a newly hired trainee officer and acquired an intelligent crime-scene trace scanner.

Solving cases earns him attribute points. The scanner's range, his strength, and his speed all improve with every case he cracks.

On his second day at work, he is assigned an ordinary missing-person case.

Within the scanner's three-meter range, bloodstains light up and hidden evidence appears, instantly changing the nature of the case.

And this is only the beginning.

Sexual murders, revenge killings, home-invasion robberies... one after another, killers who carefully concealed the truth emerge. Even a vicious case that has left the entire squad helpless begins to reveal the tip of the iceberg.

By the time the criminal erases the last clue, Lin Han is already standing behind him.

Because traces never lie, and the evidence left behind by the dead will never stay silent!
