The reason why no one could raise their voice and stop Arthur, was the highest authority, the Chancellor of the Academy who was enjoying this moment with a smile on his face.
Just like how a kid enjoys a candy while rocking his body from side to side, Eldorin was moving left and right with a grin on his face.
"Hahaha. Should I jump there and test out everything that he is hiding?" Eldorin mumbled to himself as he wondered about what else Arthur was hiding..
"But, there are too many eyes, and this could be bad for Arthur." Eldorin barely held his wishful thinking back since Arthur going all out meant revealing all his cards.
And, Eldorin already knew that Arthur wouldn't like that, since he too wouldn't like to be forced in a situation where he would have to reveal all of his strength and powers.
While Eldorin was wondering about jumping in the arena, the pros and cons of it, everyone else were wondering about what Kilian will choose.
