At the door, Teacher Li led them to the door of the office. Teacher Li pointed to the door and motioned for two people to enter.

Li Xuekai didn't come back to his senses until this moment. He raised his eyebrows and asked: "It's Professor Feng?! Is that mathematician I've heard of?!"

Teacher Li looked impatient: "Yes, so don't talk nonsense, you know?"

Li Xuekai nodded, and immediately looked at Xue Xi: "Don't be nervous!"

Xue Xi:? ?

Li Xuekai opened his mouth soothingly: "Although this big bull is really awesome, he is also a human being, don't be afraid! We are still young now, and you have proved Batra's conjecture. Our future achievements may not be better than him. difference."

Xue Xi: ... Is she a little scared where did she leak?

But Feng Xingshen should be in the big group, the one who teaches math, think about it, it's nice to see the big group again.

She raised her misty eyes. At this moment, the mist seemed to be blown away, and it was slightly bright. She took a step forward and opened the door.

Li Xuekai, who is about to persuade her again, don’t be nervous:? ?

Li Xuekai could only speed up his pace and followed Xue Xi into the office.

Everyone in the office seemed to have gone out. Not here, Feng Xingshen drove them out on the pretext of talking alone.

Feng Xingshen is a lanky old man, looking at the spirit, his eyes seem to be gleaming, but his skin has wrinkles and his hair is gray. He is wearing a decent Zhongshan suit and is looking at them with a smile. People feel cordial when they look at it.

He opened his mouth: "Are you here?"

Xue Xi slowly spoke, "You teach math?"

"Hi..." Li Xuekai took a deep breath. How could Xue Xi be so rude to Daniel? Who dares to call the other person that way to teach math?

He raised his eyes and looked at Xue Xi helplessly, then blocked her in front of him, and smiled apologetically: "Professor Feng, sorry, classmate Xue Xi is a bit straightforward, not that, she..."

Before he finished speaking, Feng Xingshen smiled, "Yes, I teach math."

Li Xuekai:? ? ?

Li Xuekai's eyes were dumbfounded. Seeing that Feng Shengshen was not hostile, he didn't seem to mind Xue Xi's name.

He turned his head and looked at Xue Xi again.

Xue Xi continued to look at him: "You are a little older than I thought."

Feng Xingshen: "..."

Li Xuekai: "..."

I've seen someone who does it, I have never seen it.

Xue Xi did not seem to have a high EQ, but how could it be so low?

He hurriedly made up for her: "Professor Feng, don't get me wrong, she didn't mean that you are old, but that you are experienced and experienced in mathematics!"

"Hahaha!" Feng Xingshen smiled: "Sister Xi is straight-tempered, and she never turns her words. He just said that I am old. I am indeed old. I am all sixty-one years old this year. ,Ugh!"

Li Xuekai also wanted to make amends for Xue Xi that he offended the bigwigs in the mathematics world before he entered the mathematics world.

But before he spoke, he suddenly caught Feng Shengshen's words, the familiar name just now: Sister Xi...

He looked at Xue Xi suddenly, then at Feng Xingshen: "Do you know each other?"

Feng Xingshen smiled and said, "This is my little friend."

Xue Xi also nodded: "It's been a long time since I met with God."

The two have not known each other on the Internet for a long time, and after Xue Xi's later Bartra conjecture, Feng Shengshen also gave her some rare mathematical information.

Recently, two people are working on a new subject: Discrete Mathematics.

Feng Xingshen sent Xue Xi a lot of professional information, and she was taking the time to study.

The more Feng Xingshen had contact with Xue Xi, the more shocked it was. It would be a pity that a mathematical genius like her didn't do scientific research.

The topics he gave her are already research topics at the graduate level, but Xue Xi can always master and learn quickly!

This is also the reason why Feng Xingshen decided to come and see her personally after hearing that Xue Xi came to participate in the Olympiad! Such a genius in mathematics is still struggling with the college entrance examination and the Olympiad, which is simply a waste.

But everyone's life is the final decision, and Xiang Shuai also specially reminded him that he shouldn't be encouraged by others, or Feng Shengshen would have admitted her to college early!

How good is it to go directly to his graduate student in the college entrance examination next year?

Feng Xing sighed and asked, "Sister Xi, are you doing well here? Are there any problems?"

Hearing this, Li Xuekai looked at Xue Xi. He thought the other party would cry out about Teacher Li's target, but he didn't expect Xue Xi to calmly say, "It's okay."

Li Xuekai was stunned.

Feng Xingshen came to see each other today, and nothing else. After the two casually chatted about the professional knowledge of mathematics, Feng Xingshen stood up and said, "Then I will go first, sister Xi. , Kyoto, you are unfamiliar with the place. If you have any trouble, remember to come to me."

Xue Xi nodded again.

Teacher Li outside the door was a little nervous, and Teacher Wei next to him asked: "Let you converge a little bit, are you right? If two people accuse us at this moment, Feng will definitely take care of it."

Teacher Li said stiffly: "What are you afraid of? The student has made a mistake and can't stop being punished?"

But from time to time to go to the office.

When all three of them came out, and seeing Feng Xing's complexion as usual, Teacher Li heaved a sigh of relief: "Old Feng, you go well."

Feng Xingshen nodded.

When Xue Xi and Li Xuekai returned to the classroom, it was just time for dinner. She cleaned up and was about to go to dinner. At this moment, her mobile phone buzzed.

Xue Xi was taken aback for a moment, and when he picked it up, he found that it was a string of familiar numbers: Xiang Huai was calling.

When she was about to answer, a voice suddenly rang: "Xue Xi! You can't bring a mobile phone to school, don't you know? How can you call during class time?!"

Xue Xi stared blankly at her big eyes and saw Teacher Li standing there at the door, glaring at her.

Xue Xi glanced at the classmate next to him who was playing with his mobile phone and bowed his head, then looked at Teacher Li again.

She was not sure when she was in class, but now she is sure, this teacher Li is targeting her.

She lowered her eyes, and Teacher Li rushed to her: "Give me the phone! You can't play with your phone during school, it's confiscated!"

Xue Xi paused.

She glanced at Teacher Li's body, a touch of disdain swept across her indifferent eyes.

But after all, she handed over the phone.

Xue Xi has always been a good student who abides by laws and regulations. There are indeed regulations in the school not to bring mobile phones. It is natural for everyone to sneak in.

If the teacher is in charge, she should hand it in.

After the phone fell into Teacher Li's hands, she didn't see it because she didn't answer the phone, so the string of numbers sent her a message: [I am waiting for you at the door and brought you lunch. ——Your Huai. 】
