章 191: Spell Makers

Arve canceled the spells and quickly drew two Magic Circles of the zero-level spell, "Fire Ball."

He then turned and, pointing at a random student, said: "Look closely at these two Magic Circles, do you see the difference between them?"

The student stared intently at the two Magic Circles for a while but was unable to answer. Then Arve asked several other students, but none of them could see the difference in a minute. 

When another student could not answer, Arve calmly said: "You all understood that the change was small, but you couldn't see it, now I will show you."

Arve's spatial ring glowed, and a pointer appeared in his hands.

"Look at the left Magic Circle - this is the standard version of the "Fire Ball", and now look at the right one, the difference is right here," Arve said calmly, pointing to one of the runes.
