He may have sounded like a rude as*hole but he couldn't waste his time bothering about it, as he left the arena once the AI announced his victory.
Instead of being prideful, Lore could have noticed that something was wrong right from the beginning of their fight because Jason was unable to release traceless poison like the one he was forced to overcome in the elemental crystal cave.
However, instead of acting carefully or even being slightly observant, Lore just charged ahead in anger which caused his defeat.
Sighing, Jason hoped that his other opponents would be more level-headed otherwise, the whole tournament for the first years would turn out to be a flop show.
Once his last fight was over, he was finally allowed to leave the arena, where he met with Greg, who seemed to have gained a few new bruises, while his mana fluctuations were still stable.
