Euan's expression turned solemn.
Kyran did not say 'can' but 'will,' implying that Mannick and his men would not stop him, rather than they could not stop him.
Seeing how Mannick did not react to Kyran's words, Euan realized the relationship between the two was not simple.
If such audacious words were uttered before Euan before this day, he would have laughed it off. If not, the Royal Knights would have already made a move and killed Kyran on the spot. But with the current situation, not to mention his Royal Knights were not present, even if he had the advantage of mage level, he had a feeling Kyran did have the ability to kill him.
What made Euan believe this was because of the unfathomable pressure surrounding Kyran. There was also the fact that he single-handedly devastated the west flank, killing several soldiers in a short amount of time.
