The Professor’s Elemental Sword

The old man's smile caused Xiao Lin to be even more confused. It seemed like the professor was instead happy that he had never gone through proper elemental sword aura education?

It seemed to be so. After repeated questioning, he found that Xiao Lin only had a little bit of instruction from the new students. He nodded, muttering, "That's good, that's good. He hasn't been defiled."

The professor continued to be vague. "Do you know why I called you here?" 

"You're tired." Xiao Lin looked at the head full of sweat on the old man. As powerful he was, his body did not look like he could take much now, and his moves just now exerted him to this degree.

The professor immediately glared at him, his expression terrifying.

"Ahem, I meant you wanted to teach me alone." Xiao Lin immediately changed his stance at the change of the expression.
