Mo Gao was also astonished.
In his opinion, any student that would have been shoved to him must have come into the Academy through a backdoor; there was not much future in developing such a student, and that was why he would be "wasting his time" with Mo Gao. Just now, he had spoken for so long and so much... rather than saying that he was teaching Ling Han, it was more appropriate to say that he had all of these words stuffed inside him for too long, so he desperately wanted to share them with someone else.
He did not consider at all whether Ling Han could understand what he was saying or not.
He had never thought that Ling Han would really have understood his lecture. Moreover, after digesting the information he had blurted out, Ling Han very quickly managed to form a new flash of Sword Qi.
If it was only a single flash of Sword Qi, he could still accept it. The problem was that Ling Han had already possessed five flashes of Sword Qi in the first place!
