Chu Yunfan's speed soared to the extreme, but the Demon Dragon King behind him was not slow either. Although Chu Yunfan's lightning wings and the speed his Prismatic Traveller were amazing, the speed of the Demon Dragon King was even more amazing.
His cultivation was much stronger than Chu Yunfan's, and he was able to catch up to Chu Yunfan with his profound cultivation.
"Roar!" The Demon Dragon King let out a huge roar, and kept spitting out flames or pitch-black lightning power from his mouth.
He also controlled the law divine power of fire and lightning, and at this moment, he used it alternately.
Any one of them could severely injure an ordinary Domainian, or even kill them.
However, Chu Yunfan had the Mountain River Cauldron above his head.
The Demon Dragon King was unable to break through the defense of the Mountain River Cauldron and seriously injure Chu Yunfan.
The furious Demon Dragon King kept roaring and chasing after him.
