Qingyun was probably the only villain who suffered this much.

For hundreds of years, a protagonist has always been barking at him and attempting to harm him, but just couldn’t kill him.

People respected him, feared him, secretly cursed at him, but he just wouldn’t die!

That’ll never happen.

A certain green-eyed man: Cutie, come into my arms.

Qingyun: Heh heh, Lao Zi will teach you how to behave.
