Almost every student of 10-B was surprised to hear that lightning is fire's natural ally and not the wind. They have grown up while learning something else.
As they looked at their teacher in a mix of disbelief and confusion, Azzy couldn't help but sigh inwardly because of how pathetic they appeared right now.
For an intelligent guy like him, it is something obvious, not rocket science. Not to mention, the students of this class had great scores in theoretical combat too.
Hence, he couldn't help but be slightly disappointed as they didn't live up to his expectations.
Throwing the useless thoughts away, Azzy pointed the marker at the short-haired girl in the front row, "Student Talia, what do you think will happen if one adds the lightning energy from an elemental crystal to a fireball? Note that I have a decent amount of mastery over energy control."
