Zhao Hai looked at the dark sky sect's protective formation that had been opened and smiled. He knew people like yang Chengzi all too well. They were ambitious, and ambitious people tended to cherish their lives more. In order to fight for a chance to live, they would not care about the life and death of others. Therefore, yang Chengzi would definitely agree to his conditions in exchange for his own life.
Yang Chengzi knew very well that it was impossible for the blackheaven sect to withstand Zhao Hai's attack with its current situation. As long as Zhao Hai broke the blackheaven sect's Mountain-protecting formation, he would not have another chance. He would be dead for sure.
