"Professor, you've entered the wrong classroom!"
Li Meng, sitting in the front row, was the first to notice the figure entering the room. She immediately put down the "Standard Spells" book that was making her head spin, stood up eagerly, and cluelessly reminded him, "This is Astronomy Class 08-1!"
"You've got the wrong room!"
The stick figure behind the door followed the little witch and shouted, "This is East Building 601; you don't have a class here!"
Professor Li Qihuang tilted his head, glanced at the little figure behind the door, nodded slightly, and said gently in his usual soft voice, "Ah, yes, I have not come to the wrong place."
"But we have a Curse Course right now!"
The little witch looked confused and even doubted herself as she flipped through her class schedule. After repeatedly confirming, she looked up again, reaffirming, "…it's Old Yao's Curse Course!"
