Chapter 489 (1/2)

Today, the students felt very strange. The teachers felt that they were not far from death.

Today's class is very quiet. The students of class 1309 keep their heads down and take notes carefully. No one dares to make a sound.

The teacher in front of the blackboard was writing Physics Formulas on the blackboard trembling with chalk and textbooks.

The middle-aged physics teacher was trembling like an old man.

He pushed the glasses hanging from the bridge of his nose and read the physical formula.

The physics teacher felt that he had never felt so difficult and scared in class as he is today in his thirty years of employment.

In the back of the classroom, the boy who should have been lying on the table to sleep early, was surprised to sit in his seat, take a pen, take notes and listen carefully.

If any student could live such a serious life, the teachers would be happy to cry.

But if this person is Xie JiuHeng, the teachers will only cry in fear.

What new ideas did the ancestor come up with to harm people?

Yi Nan sat in front of Xie JiuHeng. It was only one day after he said to change himself and study hard with brother Heng last time. I didn't expect brother Heng to make up his mind so soon.

Looking at Xie JiuHeng, who is very serious, Yi Nan is very pleased.

His heart was inspired.

Brother Heng began to study hard and wanted to fight for a good future. As brother Heng's younger brother, he must work harder!

Yi Nan cheered himself up, turned around confidently, and looked seriously at the physics teacher on the stage.
