The scene in the classroom had long been expected by LAN Yin.

She raised her eyes and scanned the twenty people in the classroom one by one. Finally, her eyes fell on LAN Xinning.

Others are surprised and question their age and education, and think they have no ability to teach them.

But at this time, LAN Xinning looked at herself with disdain, which made LAN Yin feel uncomfortable.

Since it makes her uncomfortable, the other party doesn't want to be happy!

LAN Yin looked at LAN Xinning, her jaw lifted slightly, and her expression was arrogant.

Her indifferent voice raised several degrees and said to LAN Xinning.

"This classmate, you don't even know the basic discipline as a student except that you don't know how to respect teachers and respect morality?"

LAN Yin said, glancing at the other 19 participants in the math competition in the classroom, and then continued to say to LAN Xinning.

"Look at what other students do. You're not a teacher. Just stand in the classroom to highlight your sense of existence?"

If someone else said this, LAN Xinning could regard it as a quarrel caused by the other party's provocation.

But LAN Yin's identity today is the team leader teacher of their junior group of mathematics competition——

LAN Yin scolded herself for disobedience in public, which was basically beating her face in full view of the public!

But LAN Xinning's identity is a student, and she really did wrong.

So at this time, she couldn't even say a retort

Besides, LAN Yin won't leave her any chance to speak at all.

"Don't find a place to sit down, do you want the teacher to invite you?" Lan Yin smiled, but her eyes were cold.

As for the "teacher" she said, naturally, it was not herself, but another person standing on the podium, Xu Fei, the leader of the youth group.

LAN Yin was young. In front of Professor Mu and teacher Xu Fei, she was so angry that she even scolded students of her age with a little domineering.

This scene really calmed all the participants in the math competition in the classroom.

Even the students of the youth group feel that the teacher LAN Yin of the youth group speaks with great momentum ~!

LAN Xinning was embarrassed when she was scolded in public. Her face turned red and her heart was angry, but she couldn't send it out.

In front of Professor Mu and another teacher, LAN Xinning felt that she had never been so oppressed!

At this moment, she couldn't help staring at LAN Yin!

Then he went to the corner of the classroom where LAN Yin had sat before and sat down.

Looking up at LAN Yin again, LAN Yin smiled and nodded satisfied with her obedience.

"Well, who has anything else or suggestions, you can say it now. If not, we should have a good chat and improve everyone's math level in two days..."

At this moment, everyone in the whole classroom found that the situation that should have been dominated by Professor Mu had become a 17-year-old girl, who crossed the professor and another teacher and arranged everyone's scene.

The girl should not have crossed the scene, but no one interrupted.

Both professor Mu and Xu Fei of the youth group acquiesced in the girl's behavior.

Professor Mu didn't say a word because he understood LAN Yin's math level and knew that Lan Yin's teaching would be more helpful to the students participating in the math competition.

As for Mr. Xu Fei, he saw that Professor Mu didn't say anything about the current situation. As a teacher, could he surpass the professor to stop it?
