The little teacher of rebirth

A week flies by, and there are only two classes on Friday afternoons in summer, which should have been greatly welcomed, but it is a pity that this is the quiz time of the math teacher Lao Cai.

As soon as the bell rang for the first class in the afternoon, Lao Cai came in with the papers in his arms. He directed everyone to open the table to ensure that there were only one person and one seat.Then the papers were passed down to the first row.

Guan Zhongzhi had a stomachache and asked for leave to go out.

Zhou Mengxi left a paper for him, then handed the rest of the paper to the back table, glanced at the question type, quickly wrote his name and began to answer the question.

The classroom was very quiet, except for the rustling sound of paper and pen. After a while, Guan Zhongzhi typed in the report, shook his hand and began to answer the paper.
