Chương 878: Chapter 877: The Realm That Humanity Cannot Reach_1

The "Heart Thunder Sword," composed of mental power and the Wind Sword Way, naturally became immensely more powerful as the Wind Sword Way was elevated to its initial completion.

However, accordingly, the mental power required to wield the Wind Sword Way at this initial completion stage was far greater than before, and after just two uses, Shi Xiaole felt his head swell with pain, unable to perform it again for some time.

"Asura Calamity!"

Two enormous black balls of Vigorous Air approached one after the other, creating voids that seemed to be surrounded by invisible chains, leaving Shi Xiaole no place to dodge.

And the Asura Martial Emperor himself charged straight at him, his body's aura shield rippling with layers, indestructible.

"Wind Fury!"

With both hands on his sword, Shi Xiaole fiercely swung out, the explosive waves engulfing everything around him.

Boom...

A figure was sent flying backward, blood and pieces of his liver spraying out from Shi Xiaole's mouth together.
