Go and Ask the Main Orb to be Shut Down!
That scene was really miraculous to the mages standing around the head master, as they already knew Arthur's orb's fate. As the orb still stood in the hands of Arthur, they knew something huge was going to happen here.
However, the head master standing here didn't share their shocking impression on Arthur, instead he was greatly humiliated and threatened by this young, nameless mage. He glanced deeply at him, with much hatred and anger, trying to figure out a way to stop this test.
"You, go inside and report a malfunctioning of the main orb, make them shut it down now, or else I won't be able to approve these test results," the head master had already found his way out, as he used his authority to threaten the academy of not approving of these test results, under the accusation of an error occurring to the main orb.
