Cain's eyes widened as he saw the Sword Avatar generate sonic booms with its feet, moving across the room's ceiling at supersonic speed.
Although Astral Wave Champion could move through the air using Air Walk, none of them could do it with such dexterity and speed, not to mention that the Sword Avatar was doing it using the same strength and energy pool that Cain's.
Cain followed the movements of the Sword Avatar with his eyes, but while his mind could follow the enemy, his body was too late to react, and a sharp pain appeared on his back.
"Ahhhh!"
A scream of pain echoed across the room as the Sword Avatar punched Cain's back with so much power that it almost fractured his spine. That attack sent the human flying away and would have been much worse if not for this one redirecting all his Astral Wave to his back at the last second.
