On the podium, Old Yao bit his pipe, chewing the bluish-white smoke, his beetle-like eyes scanning the room momentarily before nodding at the male monitor of Astronomy Class 08-1.
"Frankness!" Tang Dun stood up to answer.
"Hmm, that's a very interesting spell as well."
Old Yao turned and knocked on the blackboard, which immediately spewed out a series of well-structured spell formulas, describing in detail the spell Tang Dun just mentioned:
"...Just like your intuitive understanding, this spell is often used for gentle inquiries, where the caster hopes to obtain the most truthful answer with minimal harm. Compared to truth serum or other more coercive magical means, this spell is quite favored by the Dan Hag Wizard Rights Protection Committee."
