Kapitel 450: Perilous Situation!

When David was a Late-earth realm practitioner, his mental strength was almost equal to that of an earth realm expert. His foundation was incredibly firm and even though he wasn't as talented as the others, his way of practicing his mental energy by exhausting and then refilling his mental energy made his capacity to store energy increase bit by bit.

But now that he was now a perfect-earth realm expert, his energy capacity had increased even further, there was no way his energy would be exhausted before Long Zhi's own ever could.

Boom! Boom!! Boom!!! 

Massive blast of energy waves residue continuously exploded through their vicinity, creating and building up shockwaves.

David and Long Zhi were attacking each other ferociously, using their fastest techniques. If a mortal were to see those to fighting, they would inky be able to see two figures switching hand seals with terrifying speed.
