Immediately, Professor Deli nodded slightly, and said hello, but did not do too obvious. After all, his purpose cannot be too obvious. If he is seen through, it will be even more difficult to take Xue Xi away.

Xue Xi also smiled slightly. It was a greeting. Before he lowered his head, he heard Zhang Hao speak behind him: "Did Professor Deli just look at me? Did he look at me?"

Xie Yingying:...

At the IMO, when Deli approached Xue Xi, Zhang Hao was not by his side, so he did not know the relationship between the two.

She twitched her lips and looked back at him: "It's expensive for a person to know oneself."

Zhang Hao is delighted: "Do you think I'm too good? I don't usually see my own excellence. Alas, it's a headache."

Xie Yingying:? ?

Li Zixia burst out laughing.

On the stage, the teacher of "Linear Algebra" was also very excited. It is the dream of every mathematician to see Professor Deli and exchange his knowledge about mathematics.

You must know that Professor Deli can not be seen by anyone.

Professor Deli spoke: "May I say a few words first?"

The linear algebra teacher nodded.

Professor Deli stood on the podium and introduced himself briefly in English. Then he spoke: "Oh, I am honored to stand here today because I want to choose an exchange student. I think Both Skamford and Huaxia University are top universities, and we should communicate more."

As soon as he said this, the students below immediately raised their heads, and they wanted to be taken seriously by him.

Feng Xingshen asked: "Professor Deli, I don't know what are the conditions for you to choose exchange students?"

Deli smiled and said: "China has an old saying, called..."

He said in a strange Chinese pronunciation: "There is a fate to meet for thousands of miles."

The people below burst into enthusiastic laughter instantly.

Professor Deli has always been serious, doing mathematics, rigorous is instinct, and being able to make such a joke today made Feng Xingshen relieved.

The main reason is that this professor suddenly came to China, which is really weird.

Up to now, the country can't find out his intention.

A mathematician such as Professor Deli, but the object of competition from various countries, he always carries a dozen of M countries' R&D secrets, how could he let him go abroad?

I still remember that there was a mathematician in Country M in China, and he encountered many obstacles when he wanted to return to China. In order to prevent China from having advanced knowledge in mathematics, Country M used a lot of rogue methods and later sent top specialties. Talent steals people back secretly.

Therefore, it is definitely not easy for Deli to come to China.

After Professor Deli finished speaking, he briefly introduced the content of Skampford's Department of Mathematics, only to mention the topic: "Our college's recent research and development projects include "Riemann Conjecture", "Solution of NS Equation"... …"

He talked about several difficult projects that were of great significance to the mathematics community, which made the students in the class even more excited.

If you can join this kind of project, it can be counted in history!

After Deli finished speaking, he smiled: "So, I will select the best students to join us!"

After speaking, he glanced at Xue Xi again: "Okay, give your teacher the time, I will come to the class!"

Professor Deli and Feng Xingshen walked directly to the back of the class.

Xue Xi was sitting very far back. Only Zhang Hao and the others were behind, and there was a row of empty seats behind.

Professor Deli didn't know whether it was deliberate or casual. He took Feng Shengshen and Teacher Guo and sat directly behind Zhang Hao.

From the moment they sat there, Zhang Hao was fidgeting like a needle in his butt: "Ah, ah, Professor Deli is sitting behind me, I said he just saw me!"

Xue Xi: "..."

She was thinking, she received another micro message on her phone: [Mr. Guo is behind you, but be careful~]

It turned out to be Liu Zhao.

When everyone was in the dormitory, they added WeChat to each other under Li Zixia's greetings, but Liu Zhao never sent her a message, and Xue Xi even forgot that she still had her WeChat account.

Liu Zhao, who was sitting in the first row, secretly played with the phone, then looked back and found that Teacher Guo's eyes were staring at Xue Xi with thorns.

She felt even more proud.

She couldn't help but sent another message to Xue Xi: [This opportunity, I'm afraid you will give it to me. 】

As soon as the yin and yang voice was sent out, I saw a big red exclamation mark popping up on my WeChat!

And there is a prompt: you need to add the other party as a friend before you can send the message.

Liu Zhao:? ? ?

Xue Xi turned her black! ! !

Such a person, why not keep her in his address book without blocking her?

Xue Xi had forgotten that there was this person. Thank her for reminding her. After Liu Zhao was blacked out, Xue Xi put down the phone.

Then she started to listen to the class seriously.

The content of this lesson is very exciting, and the algebra teacher also hollowed out his mind to make a good impression on Feng Xingshen and Professor Deli.

Xue Xi also listened very happily.

Mathematics is actually quite interesting, and it is very rigorous, not as complicated as the human heart, Xue Xi really likes this subject.

Although it was a big class, it was divided into two sections. After the class was over, Professor Deli wanted to talk to Xue Xi in the name of communicating with his classmates, but he was caught by Feng Shengshen unexpectedly. "Professor Deli, what do you think of our textbooks?"

Professor Deli can only stay and say a few words to him.

And Mr. Guo, who was next to him, had already stood up and greeted the classmates in the class as if he was okay.

Everyone is quite embarrassed.

After all, Teacher Guo has been expelled from the school and he has done something like that. Everyone is disappointed in him, but now he is a student of Professor Deli...

Most of the students didn't dare to offend him, but they looked down on him, so they didn't pay much attention to it, and passed away with an awkward smile.

Teacher Guo didn't care about the opinions of these people at all. He greeted and called Xue Xi's side, and said two words to Li Zixia and Xie Yingying: "You are not serious in class!"

Who pretends to be a teacher?

Xie Yingying and Li Zixia lowered their heads and ignored him, vomiting in their hearts. They didn't think what happened to Teacher Guo before, but now they feel sick when they see him.

Teacher Guo finally looked at Xue Xi: "Student Xue Xi is really talented in mathematics. If there are better learning opportunities, I think I can definitely go to the next level."

Xue Xi looked up at him: "What opportunity?"

Teacher Guo smiled, "Of course it is an opportunity for exchange students. Do you want this place?"

Xue Xi hadn't answered yet, but Professor Deli across the row pricked his ears when he saw this situation.
