From MC's perspective:
Duel Platform,
The elemental Wizard's blue flame magic is destroying the platform and burdening the barrier.
Whereas the Weapon Wizard shows a calm expression. But he is experiencing some pressure as well.
The scorching heat coming from the blue flames made him uncomfortable. He used his weapon to eliminate most of the flame power.
But still, some sparkling flame bits had hit his body. Which causes stabbing pain and a left red spot on the targeted part.
He has understood the power of the blue flames. It's difficult to block all the attacks by simply using the weapon.
Just as he thought, the elemental wizard moved. He cast the next magic spell. Everyone thought he was like other elemental wizards who just used common magic spells.
But the next second, everyone was dumbfounded by the scene.
