Swish!
Jiang Yi let out a breath and flew as his body turned into an afterimage. The Merman Demon Thearch might have perished, but there were still a few dozen demon kings below. Since he was going to help Feng Luan and her people, he was going to do it all the way. He would kill off all these demon kings, which was at least guarantee that the Phoenix Cry Continent would be peaceful for hundreds of years.
Of course, he had already calculated it. It was going to be worth it for so many demon king corpses. If he didn't take them, he would just be letting the Phoenix Cry Continent take advantage of him.
After releasing the Massacre Intent, the remaining demon kings were immobilized. Jiang Yi slowly approached them, tossing away the nearby humans and releasing the Nine Heavens' Dragon Flames to leisurely incinerate a demon king.
