章 433: 433 Revenge

Li Li felt that Tan Rou's words made sense, so she sat back in her seat and continued studying. After all, Song Lin volunteered to be on duty for them.

The classroom in the morning was not very dirty because the students would clean it after school last night. However, he didn't know if the students in the class were deliberately messing with Song Lin. They would always throw trash behind Song Lin. Song Lin would have finally cleaned the place but when he turned around, there would still be trash around.

Xu Yan saw it too. Although he didn't like Song Lin, as the class monitor, he couldn't tolerate others throwing rubbish in front of him.

"The classroom is our home. The classroom environment needs to be maintained by everyone." Xu Yan said calmly, "Whoever litters will be punished by sweeping for a week."

Since Xu Yan had said so, the students did not dare to throw rubbish anymore. After all, Xu Yan was still a threat in class.
