The sarcasm and ridicule of the students in the class and the "big words" Lan Yin said were all calm when the class bell rang.

Before the teacher came, Lan Yin had already taken out the textbooks from the desk drawer and quickly looked them through them one by one.

She must understand the learning materials from more than 100 years ago as soon as possible in order to get results in the subsequent monthly exams.

There is still half a month left before the monthly exam. Although it seems not long, for her, it is more than enough time.

Outside the classroom door, a middle-aged female teacher wearing a floral dress and curly hair in a shawl, walked into the door and climbed to the podium.

The female teacher is Yu Zhen, who 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 glanced at the whole class.

In addition to observing whether any students skip classes, this is also shocking the students to listen to the class carefully.

After today's sweep, Yu Zhen found that Lan Yin, who was in the penultimate row, was actually holding a Chinese textbook in her hand!

When reading Chinese textbooks in mathematics class, how despised her teacher?!

"Lan Yin, are you a plenary session of your math problems?!" Yu Zhen said unhappy.

Lan Yin heard his name and looked up with conditioned reflex. He found that on the podium in front of the classroom, a female teacher holding a math textbook in her hand was staring at herself-

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

It's a math class now, but what I'm looking through is a Chinese textbook...

Lan Yin is indeed a little sorry for such a mistake.

She also answered the other party’s questions seriously.

"It should be all."

Mathematics is not like Chinese. Different eras have different scopes of knowledge to be tested.

Lan Yin can be said to be proficient in mathematics more than a hundred years later, let alone from it more than a hundred years ago?

After hearing Lan Yin’s answer, Teacher Yu, who was already a little angry, looked even worse!

"I know it? Then come up and solve this 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.

Just Lan Yin’s math level?

She may not even know how to do math in the first year of high school, let alone in the third year of high school?!

Now, almost everyone believed that Lan Yin was going to embarrass her in public~!

The question on the blackboard was quickly finished. As soon as Yu Zhen turned around, she saw Lan Yin getting up from her seat and walking towards her.

Yu Zhen:?

What did Lan Yin come up to do?!

Although she said that Lan Yin could solve the problem, she also knew that Lan Yin's math level could not solve the problem at all.

She said this and wrote it out, just to let Lan Yin retreat and admit her mistake!

As long as Lan Yin stands in her seat and apologizes and promises that she will not read other books that are not related to the course in the future.

But Yu Zhen didn't expect that after classmate Lan Yin came up, he took a piece of chalk directly from the lectern and said to her, "Teacher, please give it to me."

Then after Yu Zhen heard the voice and subconsciously retreated and gave up, Lan Yin quickly wrote a number under the topic she had asked.

——2.

After writing the words, Lan Yin put the chalk back to her original position, turned around and walked down the podium, and walked towards her own seat.

Yu Zhen:?

All students:???
Chapter completed!
