Before Avretion could finish his words, he saw the scene of Azusa suddenly punching one of the Obsidian Knights with her bare fist and that knight immediately getting blown away. This scene made Avretion to gasp. Even he did not have the strength to so easily blow away an Obsidian Knight. But then, Avretion told himself in his mind that he was not an warrior and was mostly a mage. So it was not surprising that he could not blow the Obsidian Knight away. Punching things was barbaric anyways.
While Avretion was trying to maintain his superiority in his mind, Azusa did not stop and targeted a second knight. This time she did not use her physical strength and instead used magic to create a powerful shockwave. Immediately, the second knight was also blown away.
