Sauros probably could have stopped the rock from turning into sand. Still, his reaction speed was messed up thanks to the surprise, so the group was suddenly obstructed by a wall of sand. Aion had many things to say about that, but he had to ignore it because the ax general approached and swung his ax.
Aion used his shield to block the attack, but the impact pushed his body away, and he felt like his left arm was being ripped off, and it was pushed to his back, leaving him wide open. With the enemy's power to repel attacks, Aion couldn't put any force behind his attacks or defenses. Otherwise, they would be used against him.
The ax general swung his weapon again, but since he was too into full swings, Aion managed to move his sword toward his face. When the tip of the weapon almost pierced the enemy's eyes, Aion noticed that the enemy had stopped moving, and he stopped as well since that was too suspicious.
