Extreme Speed!

On the outside, Cain's and Amber's bodies jerked. They knew they couldn't use the full effects of the black lightning less they wanted, unwanted attention. 

Hence, the black Dragon rune markings didn't appear at the center of their forehead. But that couldn't stop traces of black lightning from flowing out of their pupils. 

In this very instant, even without its full effects, Cain's and Amber's Spiritual Sea abilities were amplified beyond their peak limits dozens of times! 

Only two minutes have passed. Every other challenger disciple was still struggling. 

But Cain and Amber experienced a monstrous change. Through their essence energies, the duo understood a tiny portion of the Great Dao sensation! 

Because their essence energies can directly control a small portion of the Greater Dao sensation, they rely on this small control to break through the real-world atmosphere! 

Cain and Amber didn't waste any more time.
