The System Wants Me to Act Cute, but I Slaughter My Way Across the Immortal Realm

The male lead is bound to a Show-Off Comedy System. On the surface, he acts crazy and silly, pulling ridiculous stunts. Behind the scenes, he's ruthless and leaves no enemies alive. The more obnoxious the System gets, the stronger he becomes; the more arrogant his enemies are, the more of them he kills. He laughs and slaughters his way from the bottom to become the most ruthless man in all the heavens!
