When Noah's opponent heard the judge speak to begin the competition, he didn't think twice and already summoned up his Blessing.
As any kind of Blessing was allowed, the man was quick to create an ice knife to use during combat. In such a tight place, the man could even try to summon some kind of ice spear and shoot it at Noah, but that would open up opportunities for Noah to attack him up close, which would make him helpless and everything might go wrong. So with the ice knife, he ran to Noah, hoping to catch the rookie off guard.
