He's in the Police Force, But the System Insists He's a Ghost Messenger

Having transmigrated to a parallel world, Su Chen, a slacker in the special case team, unexpectedly becomes bound to the "Underworld System".

From then on,

The interrogation of a ruthless criminal turned into a "torture of demons."

The hunt for fugitives has become akin to "suppressing zombies."

The unsolved case became known as "the work of a ghost king".

...

Colleague: "Su Shen, how did you figure out that the murderer had a split personality?"

Su Chen looked at the [Painted Skin Ghost] on the system panel: This... is quite obvious.

Criminal: "I thought I had no flaws, how did you find me!"

Su Chen recalled the directions given by the kind old lady who was possessed by the "Earth God"...

This is the story of a lazy detective who, under the absurd guidance of a bizarre system, uses underworld skills to subdue criminals in the mortal world and unknowingly reaches the pinnacle of life!
