Chapter 699: Praying Spirit Transformation Technique_2

The ground beneath their feet shook and shuddered without end!

Grusen's attack missed, and the giant axe in his hand once again swung out consecutively, sending two black energy waves crossing each other directly towards Ye Feng, sealing off all his paths of retreat.

"Let's see where you can hide now!" Grusen bared his teeth and coldly shouted.

"Hide? Did I ever say I was going to hide?" Ye Feng sneered, and the Emperor Sovereign Sword appeared in his hand, which he then swung.

Terrible Sword Qi, like a golden rainbow, streaked out. Upon collision, it sliced through the black energy waves from the giant axes as easily as cutting tofu.

The scattered energy waves instantly destroyed the entire Treasure Vault and even half of the City Lord's Mansion suffered damage. The whole Underground City kept shaking, unable to withstand such a massive impact of energy. If this continued, it wouldn't be long before the Underground City completely collapsed and sank.
