The patriarch didn't know how his clan offended such a character. He was really unwilling. Right now, he didn't even want his son to seek vengeance. He would be glad if those who escaped carried on the Wang name and prospered with the help of his son.
He could only hope that his son would be smart enough to realize that vengeance was not really possible in the current circumstances. Even if his son's cultivation exceeded this madman, he wasn't confident that his son could walk out alive if he confronted this madman.
He had heard about men like this madman. Those rare cultivators who could leapfrog levels and kill opponents who are stronger than them. He never expected to meet such a person in this situation. Unless his son was blessed with extraordinary luck, vengeance can only be a pipedream.
