“Clone cultivation, the host becomes stronger.”

“Clone [Non-self Sword God]: Sword art technique power +200%, sword art technique cultivation speed +200%. No matter how strong you are, I will cut you down with one strike!”

…

“You never know how many clones are trying to cultivate behind the person you are talking to in front of you!”

“What does it have to do with me if my clone did it?”

“Don’t try to outnumber me cuz you can’t!”
