Retired Soldier King: I Work as an Undertaker in a Funeral Parlor.

In the past, the king of the special forces became an undertaker in a funeral parlor incognito. He originally wanted to be with the corpse to wash away the murderous spirit, but because he fulfilled his promise to protect his comrade's sister, he was forced to pick up the blade again, use a scalpel to dissect the conspiracy, and uncover the evil hidden in the city.
