The satire and ridicule of the students in the class and the "big talk" said by LAN Yin were calm at the moment when the bell rang.

Before the teacher came, LAN Yin had taken out her textbooks from her desk drawer and looked through them quickly.

She should learn about the learning materials more than 100 years ago as soon as possible in order to get results in the subsequent monthly exam.

It's still half a month before the monthly exam. Although it seems not long, it's more than enough for her.

Outside the classroom door, a middle-aged female teacher with a floral dress and hot shawl and curly hair entered the door and boarded the podium.

The female teacher is Yu Zhen. She is a math teacher in class 11, grade 3, Ningcheng No. 1 middle school.

She is thirty-five years old and has been teaching for thirteen years.

Before starting the lecture, Yu Zhen habitually sweeps the whole class.

In addition to observing whether students skip classes, this is also a deterrent with eyes to let students listen well.

Today, Yu Zhen found LAN Yin in the penultimate row reading a Chinese textbook in her hand!

Reading Chinese Textbooks in math class, how much does she despise the existence of her teacher?!

"Lan Yin, is your math problem a plenary session?" Yu Zhen said displeased.

When LAN Yin heard her name, she looked up conditionally and found that the female teacher with a math textbook in her hand was staring at herself on the podium in front of the classroom——

LAN Yin was slightly stunned, and then she suddenly reacted!

Now it's a math class, and what I'm looking at in my hand is a Chinese Textbook

LAN Yin is really sorry for such a mistake.

And she answered the other party's questions carefully.

"I think so."

Mathematics is not like Chinese. The range of knowledge to be tested is different in different times.

LAN Yin is proficient in mathematics more than 100 years later, not to mention more than 100 years ago?

Hearing LAN Yin's answer, teacher Yu, who was already angry, looked worse!

"All right? Then come up and solve the problem!"

Yu Zhen said, picked up the chalk on the podium, turned around and wrote the topic she was going to tell the students today on the blackboard behind her.

Seeing this scene, many students in the class were gloating.

LAN Yin's math level?

I'm afraid she doesn't even know math in senior one, let alone senior three?!

Now, almost everyone decided that Lan Yin was going to be humiliated in public ~!

The questions on the blackboard were written quickly. Yu Zhengang turned around and saw LAN Yin get up from her seat and walk towards her.

Yu Zhen:?

What did LAN Yin come up to do?!

Although she said to let Lanyin solve the problem, she also knew that with Lanyin's mathematical level, she couldn't solve the problem at all.

She said so and wrote the inscription, just let LAN Yin retreat and admit her mistake!

As long as LAN Yin stood in her seat and apologized, and promised that she would not read other books unrelated to the course in her class in the future.

But Yu Zhen didn't expect that after LAN Yin came up, she took a piece of chalk directly from the desk and said to her, "teacher, please give way."

Then after Yu Zhen heard the voice and subconsciously stepped back to give up her position, LAN Yin quickly wrote a number under her topic.

——2。

After writing, LAN Yin put the chalk back in place, turned and walked down the platform towards her own seat.

Yu Zhen:?

The whole class:???

What is Lanyin doing? Openly playing with the teacher?!
