Xueba, I beg you to go and escort him quickly!

Yue Pingting was stunned, "Huh? This...is this still a sub-question?"

Xu Heng, "This is a junior high school question, right? It's so simple... Oh, I forgot, you are not good at junior high school math..."

Yue Pingting glared at Xu Heng, almost choking him.

Xu Heng, "Hahaha... this question uses factorial, for example..."

Xu Heng said while writing down on the paper:

5！=5*4*3*2*1

4！=4*3*2*1

3! =3*2*1

2! =2*1

1! =1*1

"But here is an exception, the factorial of zero is equal to 1..."

Having said that, Yue Pingting directly took a pen and wrote on the topic Xu Zongyun posed:

（0！+0！+0！+0！）！=24

Xu Zongyun, "Ah..."

After a while, Xu Zongyun sighed again, and then murmured, "I won't give up!"

From the excitement again and again, to the disappointment later!

over and over again!

Xu Zongyun stayed like this at Xu Heng's house until the sixth day!

After that, Xu Yuehai's family left!

Xu Yuehai and Wei Xiaojiao made a decision, "Brother! Sister-in-law! Can we come back next year for the New Year? Or... during the summer vacation, can we send Zong Yun here?"

They are not blind, they have seen Xu Zongyun's rapid progress under Xu Heng's influence.

Xu Yueshan and Zhou Xiu'e laughed, "Xu Heng has the final say on this matter!"

Swish!

Everyone looked at Xu Heng.

Xu Heng nodded.

With this kid around, I wouldn't be so boring.

Xu Zongyun, "Thank you! Brother! I will definitely work hard in the second half of the semester! When I come back, I will definitely impress you!"

Xu Heng rolled his eyes, "Get lost!"

Watch Xu Zonghai's family leave.

Xu Heng and Yue Pingting are about to start school soon.

But before school starts...

Especially the night before school starts!

Yue Pingting knew very well that after school started, they would live separately on campus.

So she spared no expense!

She has unlocked everything that can be unlocked, and even used auxiliary "props"...

Hanfu...

COS...

……

"Xu Heng, I love you..."

Xu Heng said in a low voice, "Me too."

"Are you looking forward to school starting?"

Xu Heng thought for a while, "Why do you say that?"

"because……"

PS: I beg for all support!

Thank you for the support of [Move Times, Move Times] [Lee Sang Hyuk]!Four.

Chapter 272

School starts!

The second half of the second year of high school!

School officially starts!

Xu Heng and Yue Pingting's class is still Class 25, Grade [-]!

Their class positions haven't changed either!

The only thing that changed was the students who were transferred away!

But this has nothing to do with Xu Heng and Yue Pingting.

The first class of school is the class meeting!

Xue Laiyun rearranged the seats of all the students!

And let the monitor take people and himself to get textbooks and materials.

Of course, a new semester, a new day, there are still many things to do.

In fact, many things are very similar to last semester.

The only difference is that the students with better grades all sat in the bottom row and the bottom row this year.

This completely dumbfounded the students who came in to choose a seat later.

Especially those newcomers.

They all scratched the back of their heads, dumbfounded.

"Wait! What's going on? What's going on with class 25?"

"Don't talk about ordinary classes, even those other rocket classes, students with good grades, don't they all sit in the front?"

"Why are they vying for the last row?"

After thinking for a long time, they figured it out.

Hemp egg!

Xu Heng is in the last row!

The top three in the class all chose the last row!

Others followed suit.

What is even more legendary is that because of Xu Heng, Yue Pingting went from the bottom one in the class to the third in the class!

This is for all to see!

Who doesn't want to improve?

Who wouldn't want to be with Yue Pingting and take some European energy!

Xu Heng looked around, "Uh..."

Even Tang Yongxue was ahead of himself!

The penultimate row!

This guy wasn't like this before.

"Hey……!"

Xu Heng raised his eyebrows, "Tang Yongxue, didn't you used to be beaten to death and never sat in the back three rows?"

Tang Yongxue smiled bitterly, "Learning is very important!"

Xu Heng said again, "You said that you can study anywhere!"

Tang Yongxue, "%￥##@#￥..."

Xu Heng, Xu Heng!How do you have such a good memory!

Hey……

Yes!

I, Tang Yongxue, finally lived the way I hate the most!

Seeing Tang Yongxue deflated, Xu Heng smiled and lay down on his stomach.

Just get down here!

Yao Ruiyi ran over to Xu Heng in a panic.

"Xu Heng! Xu Heng!"

Xu Heng looked helpless, "What's the matter, teacher?"

It's only the first day!

It's only the first day of school!

Please, let me stop for a day, can't I?

You are too anxious!

Yao Ruiyi, "A foreigner came to you...he can speak Chinese...he said he came here because of his reputation!"

"He also said that he has been waiting for a long time for our Yunshan High School to start, just to meet you and ask you for advice in person!"

Xu Heng frowned, "A foreigner? What does it look like?"

Yao Ruiyi, "Gray-haired, maybe 60 years old...with glasses..."

Xu Heng probably thought about it, it wasn't those people from Oxford University!

Who would that be?

Yao Ruiyi brought him to the principal's office, at the moment the principal was entertaining the foreigner cautiously.

"Boom boom boom!"

There was a knock on the door.

The headmaster stood up, "Come in!"

At the same time, the foreigner got up and turned to look at the door.

He also arranged his suit and looked serious.

The door was opened by Yao Ruiyi.

squeak-

Xu Heng walked in.

The principal smiled, and the foreigner looked at Xu Heng with great respect.

Xu Heng, "Hi principal, this is...?"

The principal explained, "I just found out that this professor came here in admiration! After he learned that your study room is very good, he has always been in admiration. So after learning that our school started, he couldn't wait to come here."

Xu Heng stepped forward and shook hands with the foreigner.

He was so excited that there were tears in his eyes, "Huh! I finally saw myself today! Hello! Xu Heng! My name is Kaiwen, and my Chinese name is Liu Kaiwen. Just call me Kaiwen!"

He is fluent in Chinese, "I have liked your culture for more than 20 years!"

"I'm Wu Liubai, a former colleague of Professor Wu. During the New Year, I had a video chat with Professor Wu abroad and learned about your calligraphy from him!"
