Zi Qingjian was truly tall and large, standing behind him, Nian Bing could not see anything. All he could hear was a voice from inside the classroom, "It's Xiao Zi, huh! Who allowed you to disrupt my class so sneakily, couldn't you find me when I wasn't teaching? Stay outside for now, we can talk when I'm done teaching."
Zi Qingjian responded, "I'm sorry for the disturbance. I'll wait outside." After speaking, he quickly backed out of the room. As he exited, Nian Bing got a brief look at the classroom. It was immense, with seemingly one hundred or more students inside. It appeared all the students of the magical department were gathered within. From Zi Qingjian's attitude towards this Director Hei, it was clear that the head of the magic department held a high position in the academy.
Closing the classroom door, Zi Qingjian turned back to Nian Bing and smiled, saying, "Brother, you really are a mage! We have to wait now though, Director Hei has a rather short temper."
