"Students, the earth is our common home, if the solar system is destroyed, if we don't flee with our homeland, how can we escape? The Spaceship Faction is a complete fallacy, and I hope you will not be fooled by the Spaceship Faction's remarks. ”

Yang Zhihe once again instilled the concept of the Earth School in everyone on the podium, and then said: "Before today's class, I will inform you of two good news. The first good news is that Jiangcheng No. 1 Underground City has been completed, and it is expected that in three months, our school will be relocated to the underground city as a whole. Among the first batch of people to enter the city, mainly minors under the age of 18, the elderly over 60 years old, and the disabled and sick who are unable to take care of themselves. In addition, minors under the age of 14 and those who are unable to take care of themselves can bring a guardian into the city. ”

Yang Zhihe's words fell, and the whole class suddenly burst into a burst of enthusiastic cheers.

For most human beings, the dungeon means a safe new home where there are no more unexpected disasters, and it is the cradle where humanity officially sets sail and sets foot in the starry sky.

Therefore, the news brought by Yang Zhihe quickly sparked a heated discussion among the whole class.

Yang Zhihe didn't speak, just looked at it with a smile, and it wasn't until everyone's enthusiasm gradually dissipated that he announced the second news: "In addition, in the provincial mathematics competition not long ago, Pang Xuelin from our class won the first prize with a full score, let us congratulate Pang Xuelin with warm applause!" ”

This time, the response was not enthusiastic.

The applause rang out sparsely, and the news did not cause any waves in the hearts of the students in the second (11th) class of high school.

The students have long been accustomed to this kind of news, for them, Pang Xuelin is not news to take the first place, and it is news if he can't win the first place.

Pang Xuelin was a little surprised, but he didn't care too much, for him, even if he won the IMO gold medal, it didn't mean anything, but how to get rid of the identity of a high school student at this stage is the most important thing.

At the end of class, Yang Zhihe found Pang Xuelin and told him about the National High School Mathematics League, so that Pang Xuelin could get ready.

Pang Xuelin agreed.

Under normal circumstances, the National High School Mathematics League will select 180 people to enter the winter camp, and the winter camp will eliminate another 140 people, leaving 40 people to enter the national training team, and finally, six people will be selected from these 40 people to represent China in the International Mathematical Olympiad.

Yang Zhihe naturally hoped that Pang Xuelin could become the last six.

finally survived until the end of school, Pang Xuelin picked up Yao Bingxia and rode home.

The sun still hung in the west for a whole day, as if nothing had changed.

"Xiao Xia, how do you feel about being in a new class today?"

Pang Xuelin asked Yao Bingxia with a smile.

Yao Bingxia blinked a pair of dark eyes and said, "The teacher and classmates are very good to me, Brother Xiaolin, I heard the teacher say that in three months, we will all move into the dungeon, do you say that we don't have to worry about the sun when the sun is shining?" ”

Pang Xuelin smiled and said: "I'll tell you, this is even more terrifying, if we are on the surface, if the sun flashes, we will be like being shot by a high-energy laser, and we will be vaporized in an instant, and there will be no pain at all." If it's in a dungeon, it's like meat being put in the oven, slowly cooked......"

"Brother Xiaolin, don't ...... Say no more, I'm scared...... We're not going to the dungeon, let's escape in a spaceship, okay......"

Pang Xuelin laughed, he didn't expect Yao Bingxia to be so careless when he was a child, and he was quite cute.

But Yao Bingxia reacted: "Brother Xiaolin, you lied to me? ”

Pang Xuelin smiled: "I didn't lie to you, it's just that the sun flash didn't happen so quickly, and when it happened, our earth would have been out of the range of the flash long ago." ”

"Really?"

"Of course it's true, when did I lie to you?"

"You lied to me just now......"

……

Back at home, Grandma was cooking, while Grandpa and Yao Jianzhong were playing chess in the living room.

Pang Xuelin sent Yao Bingxia to do his homework, and moved a chair to the chessboard.

"Stinky boy, what's the matter with me?"

As soon as Pang Shaoan saw Pang Xuelin's appearance, he knew that this kid had something to ask for himself.

Pang Xuelin smiled: "Grandpa, can't I watch you play chess with Grandpa Yao if it's okay?" ”

Pang Shaoan said lightly: "General...... Well, it seems that the matter is not small! ”

Pang Xuelin said a little helplessly: "Grandpa, I only have one small request!" ”

"Say what you want!"

Pang Xuelin said: "Grandpa, I don't want to go to high school anymore!" ”

"What? What are you going to do when you're not studying? If you don't have a skill, no one wants you as a worker in this era! ”

Pang Shaoan said with a glare.

Pang Xuelin hurriedly said: "Grandpa, I just don't want to go to high school, I have already mastered the knowledge of high school, and there is no point in continuing to read, the results of the provincial mathematics competition came out today, I won the first prize, and then I should participate in the National High School Mathematics League, and then represent the national team in the IMO ......"

Pang Shaoan frowned and said: "Since you have won the award, don't think about other things, and prepare well for the next competition is the right way." ”

Pang Xuelin said: "Grandpa, you see if this will work, in the next year, I will go to Jiang University to audit, and then the math competition will not be left behind, I promise to take an IMO gold medal back to give you face!" ”

"Do you want to go to Jiang University to audit?"

Pang Shaoan was slightly stunned, and glanced at Yao Jianzhong on the side.

Pang Xuelin nodded and said, "Yes, there is no point in me continuing to study in high school, and I don't want to waste time in school anymore." ”

Yao Jianzhong said with great interest: "Xiaolin, if you go to Jiang University, which major do you want to study?" ”

Pang Xuelin said: "Materials science, in the next few decades, the main attention of human beings will be spent in the field of engineering science and technology, although basic science is important, but the probability of being valued is not high, at least before the earth is out of the range of the sun, I hope I can contribute to the Wandering Earth plan!" ”

Pang Shaoan said: "Xiaolin, it's good that you have this heart, but do you think you are ready to go to college?" ”

Pang Xuelin smiled bitterly: "Grandpa, in fact, I have read a lot of college textbooks before, and I have been studying calculus, probability theory and mathematical statistics, linear algebra, mathematical analysis, abstract algebra and other subjects by myself for a while. Let me tell you this, I have done the IMO test myself privately, and there is basically no difficulty for me. If you don't believe me, let's make a bet, you can test me casually, as long as there is a question that can't be answered, then I didn't say anything about it! ”
