"Haha." This time, it was Tang Xi who was laughing. She casually looked at her deskmate and sneered. "Why? Why should I solve some more problems as you ordered? Who do you think you are?"
"Peng Yu, my name is Peng Yu. I'm the commissary in charge of studies of the experimental class." Peng Yu stared at Tang Xi and said coldly, "Why do you refuse? Is it because you dare not or you just don't have the ability?"
"Haha." Tang Xi turned to Pu Guoqing who was standing on the platform and didn't speak, and she asked frowning, "Mr. Pu, why don't you speak? You don't believe me either?"
Pu Guoqing surely believed her, because he had accidentally seen this girl solving math problems on the blackboard once he passed by the experimental class of Grade One. She was really fast at solving those math problems! But in order to convince and motivate the students, he must have Xiao Rou solve some problems on the blackboard, at any expense!
