Gilderoy's mana exploded, exerting enormous pressure on his surroundings. His aura felt like a rudely awakened beast, pressing down on the hearts of those who could feel it.
His golden eyes flared dangerously, then he slammed the butt of his staff on the ground and yelled:
"Nihility Zone!"
Zwang!!
An enormous magical circle appeared with him at its center; its size covered every square inch of land there was in this 'playground.' It then released a buzzing sound that fluctuated all over the world, and then...there was silence.
The atmosphere turned strange and eerie. Even the crowd couldn't understand what Gilderoy did just now because the spell had no visible effect; they even thought that the spell failed.
This pause was very brief. Once again, the brothers began their onslaught against their father; this time it's even more ferocious than before.
"Hoho..." Cedric let out an impressed laugh as he met the ferocity of his sons calmly.
