Although fighting for eleven straight hours was strenuous, members of the Deus Behemoth Race had a racial advantage in terms of stamina, so despite being tired, they were still fine. Many of them turned to Cain as they expected the young man to be completely exhausted, as they saw how he maintained his domain for the entire eleven hours while fighting. Still, to everybody's surprise, he looked better than all the others.
Cain was not faking it, as he really was fine. No one here had an Ego Wave at the Third Realm, so they could not detect his Astral Wave even if he did not use his red mask. His dual cultivation would be evident if he used Astral Wave for spells, but no one noticed how he circulated a small amount across his body from time to time to keep his stamina.
