The short and straightforward speech made the atmosphere in the hall quite awkward.
The culprit did not know that his words were quite arrogant to these people. Heero was just being honest with his words though.
However, the people in the hall who heard his words thought differently. His words sounded arrogant to them.
Especially for the other Hero Instructors, Heero's words sounded extremely arrogant to them.
Heero's words implied that Emperor Class Hero was easy to train. Even though they were displeased, none of them also could refute Heero's claim.
Sun Zhou Yi and Musashi Hirata were just promoted to the Emperor Class Hero. Two disciples at once, his accomplishment could not be belittled.
But still, Heero's words hurt the Hero Instructors' pride. It was as if they were incompetent in their jobs.
