"Hmm, this..." Li Zheng was uncharacteristically flustered, "Teacher Sun is a well-known Chem Competitions teacher in the country; I've heard of him."
Wu Shu and Ou Xing Zhuo exchanged a look, and then Ou Xing Zhuo's face suddenly twitched, his facial muscles contorting into a series of sleazy expressions, before he finally chuckled at Li Zheng, "Heh heh... heh heh... "
"Pfft..." Li Zheng burst out, "That's too damn accurate."
"I appreciate the flattery." Ou Xing Zhuo then rubbed his face to revert to normal, "I liked Jim Carrey's movies when I was young and inadvertently trained my facial expression skills. Sorry for the laugh."
Wu Shu also chuckled, patting his little brother, "Busted, huh?"
Li Zheng hurriedly explained, "No... I saw Teacher Sun in a video... There are videos of his lectures on the forum."
"Which one? Find it."
"Wait..." Ou Xing Zhuo suddenly brightened his phone, "Old Sun seems to have admitted it himself."
