Athan really didn't know how powerful his body had become because he was crazily training in the saint-grade warren-dimension for three months without taking a break.
In that dimension, all body chaotic powers were something that could make hundreds of saint-realm powerhouses, and he absorbed all of them without bothering to comprehend them.
He just forcefully used their raw chaotic powers to refine and strengthen his body cells that were constantly limited broken by his void pulse.
Not to mention, he was also eating the meat of saint-grade chaos beasts that Taejin killed.
Seeing the crazy training of Athan, Izarin Monarch almost pissed his pants and was wondering from where this madman came here.
So there was no way in a million worlds that Lithen even put a scratch on Athan.
