Chapter 686: Sword of Promise

The massive pain caused Zhao Fu to continuously roar, and traces of blood appeared all over his body. Zhao Fu had used up most of his strength by now, and the massive power had squeezed Zhao Fu into a ball.

"Arghhh!!" Just as Zhao Fu was about to explode, he cried out in pain, and the Earth Realm Mark on the back of his hand gave off a bright rainbow light, and a rune appeared on Zhao Fu's forehead.

This rune was quite unique, and it seemed to be formed from many different runes. It gave off a mysterious aura.

Shing!!

A clear sword's hum sounded out, and everyone saw a sword light that seemed to tear through the sky. That terrifying power caused everyone in the Trial Space to feel as if they had dropped into icy water, and their bodies and souls trembled.

Just what had happened? Why was their battle so terrifying? By now, everyone could see just how monstrous this battle was.
