Zi Qingjian said loudly, "Director Hei, it's me. Why did you attack without distinguishing friend from foe?" As he spoke, he pushed open the classroom door and looked inside with annoyance.
Zi Qingjian was so tall that Nian Bing couldn't see anything standing behind him. A voice from the classroom came, "Oh, it's Little Zi! Why are you sneaking about, disturbing my class? Can't you find me when I'm not teaching? Wait outside for now. We'll talk when I finish my class."
Zi Qingjian said, "Sorry for the disturbance. I'll wait for you outside." As he left the classroom, Nian Bing could glimpse a large classroom filled with at least a hundred students. It seemed all the magic department students must be there. From Zi Qingjian's behaviour towards Director Hei, it was evident that the director was a high-ranking figure in the academy.
