Chapter 784: Prince of Netherworld

Swoosh!

A black figure swept toward the Dragon-Phoenix Pool. The change of events stunned Mu Chen, but he reacted quickly. When he noticed the figure, he automatically attacked him. His palms were glittering with formless lightning, and the Netherworld Thunder Heart instantly thundered.

Throughout the years, Mu Chen had gone through many life-and-death battles, and he was very experienced in combat. Within this short span of time, he did not use his spiritual energy. He used the quickest method, which was the unfathomable Netherworld Thunder Heart.

Boom!

When the shrieking thunder sounds resounded, dark light swirled out from the black figure and speedily devoured the thunder.

However, the movements of the black figure suddenly stopped.

This pause made the figure lose his opportunity. Cai Xiao disappeared into thin air, and in the next instant, she re-appeared before the black figure. She quickly tapped her fingers.
