I! Eternal Black Hand, Destined Villain

Chen Jinfei, a boy from Earth, travels to Tianxuan Continent. He wanted to hug the hero's thigh, but accidentally activated the super villain system. As long as you do bad things that fit the villain's character, you can gain villain points and exchange them for magical artifacts. Since then... Tianxuan Continent has had a villain who specializes in stepping on children's balls and grabbing the heroine's twin ponytails. ... Many years later, he has become the biggest villain in the mainland! He always flaunts himself: "I can't be too bad for a villain, right?"
