Coming to his father's grave again in the morning, Xu Yun took out the copies of various certificates he had obtained and burned them together with the coins, hoping that his father could share the joy of this honor.

After Chinese New Year's Eve, Xu Yun and Chen Shihe went to the county town to stroll, after all, this time is the most lively.

In the middle, they also went to watch the movie Little Wrecking Ball to witness the rise of domestic science fiction movies.

Compared with other audiences who were shocked by the movie, Xu Yun thought about whether this kind of planetary engine could be made in reality.

But in the end, he chose to give up, after all, mankind has not even solved the energy problem now, let alone the planetary engine that propels the earth to sail in space.

Since most of the equipment and instruments in the solid-state battery laboratory are already in place and ready for use, only two Ph.D. students in related fields have been recruited from overseas, but they can try to make the first metal all-solid-state battery with the technology that has been thoroughly researched in their minds.

In this case, Xu Yun couldn't stay in his hometown for a long time, and he was ready to return to Jingzhou a few days after the Spring Festival.

It's just that he still has an acquaintance to meet before leaving.

……

"According to the address, it should be here, Mr. Su's new home is really hard to find."

At the door of a residential floor in Pingzhou City, Xu Yun carefully checked the house number in front of him and rang the doorbell.

For Su Yushan, he is undoubtedly grateful in his heart, and learned that the other party had a child last year, and since he is in his hometown for the New Year this time, he must go over to see it.

After about ten seconds, I saw the door open from the inside, revealing Su Yushan's familiar figure.

Looking at it, perhaps because of having children, Su Yushan has slightly grown a little longer than a few years ago, but her figure has not been out of shape.

Su Yushan saw Xu Yun standing at the door, and the whole person was stunned at first, and then her face was full of surprise.

"Xu Yun."

"Why did you come here all of a sudden?"

It seems that he didn't expect Xu Yun to come to see him at all.

In her many years of teaching, there is no doubt that Xu Yun is the proudest student for her.

But most students tend to think about their high school teachers after graduation.

Especially those like Xu Yun who have achieved dazzling results.

It can be said that I am very happy to be able to send her a blessing text message during the New Year's holidays.

As a result, Xu Yun not only did it, but also personally brought gifts to the door, so that she could not be moved.

Xu Yun didn't think about Su Yushan's feelings at the moment, and when he saw that the other party was a little stunned, he shouted.

"Teacher Su."

Hearing this, Su Yushan immediately came back to her senses, and then remembered to hurry up and beckon Xu Yun to come in and sit.

"Come in, you can come when you say you come, and buy something."

"Isn't this congratulating Mr. Su, on your daughter." Xu Yun put down his things with a smile on his face, and then took over the conversation.

"Then the teacher will thank you."

Su Yushan also smiled at this moment, and walked to the drinking fountain to take a cup of tea from Xu Yun.

Immediately, after a few small talks, Xu Yun knew that Su Yushan's husband would not be at home, and as for the daughter, he was sleeping soundly in the room, and he was worried about waking him up, so he just went into the room and hurried out.

After the two sat down on the sofa again, Su Yushan took the lead in opening the conversation.

"I haven't congratulated you on winning the Wolf Prize in Mathematics, you are the most outstanding student in our No. 3 Middle School since its establishment."

"It's all teachers, you teach well." Xu Yun replied when he heard this.

Although these words sounded very happy, Su Yushan knew that she didn't make much effort.

"I didn't teach you much, you can get to where you are today because your talent is high enough." She shook her head and replied with a serious expression.

Then they talked about the high school and the teachers of other subjects.

After talking for more than half an hour, Su Yushan suddenly thought of something and took the initiative to speak: "By the way, there is something that the school wants to ask you for help." ”

"No. 3 Middle School is my alma mater, and I will definitely help where I can." Xu Yun replied generously.

He knew that Su Yushan was not a character who liked to find someone to help, and since he said it, it showed that the matter was still more important.

In any case, he came out of the third middle school, and it is normal to do a little help to his alma mater, as long as it is within his ability.

Su Yushan saw that Xu Yun agreed, and a touch of joy suddenly appeared on her face.

Immediately, he did not delay anything, and was busy telling the details of the matter.

"That's the case, isn't the third year of high school going to start in two days, and the school wants to invite you to give them a 100-day pledge meeting."

It is already a school tradition to hold a 100-day pledge meeting for senior high school students at this time of year.

The purpose is to allow senior high school students to seize the last time and work hard to improve their scores.

Xu Yun also participated in it at the beginning.

Under normal circumstances, the oath meeting is presided over by the school leaders, but who made the third middle school have a Xu Yun.

With this kind of condition, we must find a way to take advantage of it.

In fact, as early as last year, the school mentioned this matter and handed over the task of inviting Xu Yun to Su Yushan, but Su Yushan was afraid of affecting Xu Yun's studies and was embarrassed to speak.

I happened to rush to Xu Yun today, and she mentioned it by the way.

"Let me hold a pledge meeting?"

Xu Yun was a little surprised when he heard that what Su Yushan was talking about.

A few years ago, he participated as a senior in high school, but he didn't expect to preside over the 100-day sprint pledge meeting now.

"You improved your grades so quickly back then, and now you are the youngest winner of the Fields Medal and the Wolf Prize in Mathematics, which can be said to be the idol of the whole school."

"If you show up, they're going to be very excited."

"Maybe it can make a lot of people decide to sprint."

Su Yushan introduced the situation of the third middle school to Xu Yun, I don't know if she remembered the past, and there was always a faint smile on the corner of her mouth.

As soon as the words fell, she seemed to think of something, and did not forget to add a sentence later.

"Of course, if you don't have time, forget it, and then you can record a video for the junior high school students."

If you think about your own example, it's really good to motivate high school juniors to avoid giving up on themselves in the final months.

According to the tradition of the sixth year of junior high school, it will not delay him for long.

Besides, he really hasn't been back to his high school alma mater for a long time.

The thought stayed here, and he didn't hesitate any longer, and immediately made a promise to Su Yushan to agree to this matter.

"I promised Mr. Su, but it is better to hold it earlier."

"I'm relieved to have your words, how about the date be placed on the day of the start of the third year of high school." Su Yushan saw Xu Yun agree, her face was suddenly filled with a smile of joy, and she was about to pick up her mobile phone to tell the school the news: "I want to quickly tell the principal the good news." ”

After confirming this matter, Xu Yun did not stay at Su Yushan's house for too long.

There is no meaning of staying to eat.

Su Yushan obviously also knew Xu Yun's character, so she didn't keep it too much.

……

……

Time passed minute by minute, the winter vacation ended in a blink of an eye, and the senior high school students also returned to school one after another.

Through these last difficult months.

For sophomores and freshmen, the start of school is one or two days later.

At noon, on the campus of Ping Chau No. 3 Middle School, many students who returned to the classroom after eating were carrying stools to the playground, and everyone was confused about what was going on.

"Why is there a pledge meeting just after the start of school, this is still some time before the 100th day, right?"

"I didn't start so early in my third year of high school last year."

"Maybe it's trying to add a sense of urgency to us, but we only have three or four months left to sprint."

"I think that the future is undecided, you and I are dark horses, don't forget that Xu Yun, the former senior of our school, has relied on the past few months to raise his scores."

"People just didn't want to learn before they had talent, and you asked yourself if you had this talent?" A girl who was passing by with a stool heard several boys in the class discussing the pride of the third middle school, and replied mercilessly.

When several boys heard this, they felt that it made sense, and they immediately lost their desire to discuss and walked into the class team and sat down.

And the proudest senior in their mouths is in the principal's office at the moment.

"Thank you for your support of our No. 3 Middle School, I couldn't believe it when I heard Mr. Su say the news."

In the office, the principal Sun Hai talked to Xu Yunpan very politely, his mellow face was full of smiles, and he didn't dare to put on his own principal's shelf.

Xu Yun's achievements now, anyone with a discerning eye can see that he will become an academician sooner or later in the future, and he is an ordinary high school principal in the city, so he is naturally nothing in front of academicians.

"No. 3 Middle School is my alma mater, and this is what I should do." Xu Yun said politely when he heard this.

The two were talking, when the dean pushed the door open and walked in.

"Headmaster."

"The students are all here."

"Okay, let's get over here." Hearing the reminder, Sun Hai first responded to the other party, and then turned his gaze back to Xu Yun and said, "Let's go to the venue now, I guess the students will be very excited to see you." ”

"I want to see these juniors too." Xu Yun nodded.

Soon Xu Yun followed Sun Hai to the playground, and when he saw the senior high school student sitting on his bench according to the class team in front of him, he also felt a lot of thoughts, as if he had returned to his high school days.

However, it is worth mentioning that he did not go directly to the stage, but Sun Hai went over to warm up first.

"Everyone stay quiet and pay attention to the venue records."

On the podium, Sun Hai picked up the microphone to maintain discipline, and then began to talk about today's highlights.

It can be regarded as unprecedented, and there is no delay.

"The reason why the 100-day pledge meeting was held in advance today is because the school has invited a very special person to preside over you, and I hope you can not give up easily after today, and strive to review hard and improve by 100 points in the last few months."

"And I believe everyone will be familiar with this person, he is the greatest pride of our Pingzhou No. 3 Middle School."

"Let us warmly welcome Dr. Xu Yun, the youngest winner of the Fields Medal and the Wolf Prize in mathematics, to preside over today's 100-day sprint pledge meeting."
