Cloud Gate Supreme

Red and black demonic energy shot straight into the sky, and streaks of lightning raged across the earth. The monks looked at the sky in horror. The man called Yun Zun, who once saved the world, now opened the gate to the Demon Realm with his own hands. "Why did you fall into the devil's path?" The monks asked puzzledly. The man didn't answer, his light flashed, and he went straight into the demonic realm.
