Su Bai quietly enjoys life, but is disturbed by those **creatures who can only come out at night. He also catches the attention of Muzan, the Demon King.
Muzan: Can humans really regenerate this well? If I can study him, I might finally achieve my ultimate evolution! Bring that guy to me!
Common demons: dead!
Lower Ranks... dead!
Upper Ranks... dead!
Su Bai: Please stop coming here to die. Every time I kill you, I have to clean up afterward. It's such a pain.
At long last, fed up with it all, Su Bai goes to find Muzan and blows his head apart with one punch.
Su Bai: So you're the one whose head got stuck in a door and decided to come after me? And you keep sending your employees over to die one by one, you piece of trash! Die!
