The void space was only enough to buy a few seconds for the demon, but that was more than enough. It kicked the ground and put some distance between them, then came in with a slash with its claws and deflected the attack.
Oliver still didn't budge. He swung down at full speed, the sword ripped through the void space and reached the demon.
Forcefully ripping through the void space caused a heavy turmoil in the space around, ripping through the trees and cutting them down.
"You are really something else, human," the demon said. He maneuvered in a way that was out of the ordinary and dodged the attack.
"Let's take this seriously," the demon said. He compressed space around his fist and threw a punch.
"Demon art, first form, void fists."
Oliver could feel the immense power seeping out of those fists. He immediately stepped back and used the sword to block.
