Trying to get help from Heaven
"Endless Void!"
Qin used his Endless Void skill and sent him to the world of darkness. A place where people can't survive unless they know the Space Law. As for coming out, it would be even harder than that.
Qin wanted to use the Dark Space but he realized that the demon was truly strong. Even with his sword cultivation and law, he could barely stand against him. The only advantage he had was the endless amount of Sword Intent and stamina.
With these two, he had no problem facing off against the demon. But, he had to please Heaven in order to get into her good side. He had two plans in his mind. First, he could try to impress her and add her to his harem. Or, he could become her close friend, enough to help him in this case.
"You are really strong." Heaven stared at him deeply and states with deep emotions coming out of her mouth. She heard their conversation very closely. And, if Qin was really planning something like that, then she could be one again.
