But Pang Xuelin can't say these words now.

He's just a fifteen-year-old high school student, and no one cares what he thinks.

Not to mention, all this is just his speculation, and he is not sure if it will happen in the end.

Early the next morning, Pang Shaoan and Pang Xuelin came to Jiangcheng Middle School and found Yang Zhihe, the principal of Jiangcheng Middle School and Pang Xuelin's homeroom teacher.

At the beginning, when Pang Xuelin came up with his own ideas, the principal and Yang Zhihe disagreed.

But when Pang Xuelin easily completed several sets of IMO competition papers and got full marks on them, they had nothing to say.

However, they made a request, Pang Xuelin must continue to represent the school and continue to participate in the National High School Mathematics League before he can be released.

Pang Xuelin agreed.

After getting Jiangcheng Middle School, Pang Shaoan took Pang Xuelin to Jiangda again.

With Pang Shaoan's relationship, it is not too simple to want to be an observer in Jiang University.

In particular, after Pang Xuelin took out the results of his middle school days and various award certificates, the deputy dean of the School of Materials Science and Engineering, who was responsible for receiving them, immediately made a decision, as long as Pang Xuelin can enter the national training team in the next national high school mathematics league, Jiang University can directly recruit for admission, and there is no need to participate in the college entrance examination.

Pang Xuelin didn't care too much about this, his grades in other subjects were not bad, when he took the college entrance examination in the real world, his test score was 728 (total score 810), more than 20 points higher than the score line in Qingbei, if it weren't for his grandfather, he wouldn't have chosen Jiang University at all.

The next thing he had to do was to show his abilities as quickly as possible, lay the foundation, and then find the right time to take out the flying blade material and graphene aerogel metamaterial.

There are many contents to be learned in materials science, not to mention the basic courses, physical chemistry, materials chemistry, analytical chemistry, organic chemistry, polymer chemistry, materials physics, material mechanics...... Each course takes a lot of effort.

Pang Xuelin found the curriculum schedule of the undergraduate stage of the materials major, listed the class time of the professional courses one by one, and then formulated his own study plan.

With the audit card of Jiang University, you can participate in experimental classes, you can apply for a library card and a canteen meal card, except that you can't take the exam to get credits, Pang Xuelin is no different from an ordinary Jiang University student.

Moreover, the library also has a computer, through which Pang Xuelin can access the Internet and obtain all kinds of information.

Next, Pang Xuelin first rode Yao Bingxia to school every morning, and then went to Jiang University, if there was no class in the morning, he would show up in the library on time, wait until the end of the afternoon class, and then take Yao Bingxia home by the way.

Pang Xuelin seems to have returned to his previous high school days, with endless books to read and endless exercises to do every day.

He is very grateful to his grandfather for cultivating the study habits he has cultivated since he was a child, good study habits and hard work, Pang Xuelin's name quickly spread among the teachers of the School of Materials.

Teachers in almost every class have encountered the scene of being stopped by Pang Xuelin to ask questions after class.

For this studious teenager, they naturally spared no time to answer.

Pang Xuelin is like a dried sponge, hungry for all aspects of materials science.

Although most of his energy has been on mathematics in these years, the foundation of physics and chemistry is there, coupled with many years of learning experience, so Pang Xuelin soon has a more systematic understanding of materials science.

At least in the papers on flying blade materials and graphene aerogel metamaterials, he has gone from being confused at the beginning, and now he can gradually see the way.

……

Two months passed in a flash.

In September, Pang Xuelin participated in the National High School Mathematics Competition on behalf of Jiangcheng Middle School, and unexpectedly obtained a perfect score and was successfully selected for the Chinese High School Mathematics Olympiad Winter Camp.

It's just that the winter camp won't start until December, and it's still early.

And Pang Xuelin has also decided that he is not going to go to the winter camp and training team, anyway, he is just brushing up on exercises and various trainings every day, which makes no sense to him.

As for how to get the teachers of the winter camp to agree at that time, this is not a problem, you just need to take a few sets of IMO test papers, spend a little time to finish them, and throw them in front of the other party.

In the past two months, Pang Xuelin has also gained a deeper understanding of this era.

Because of the solar crisis, the technology tree in this world seems to be a little crooked.

This is a world with a high level of heavy industry.

Heavy industry accounts for more than 90 percent of GDP.

Engineering technology has reached its peak, otherwise there would be no way to build a behemoth like a planetary engine.

In addition, metallurgy, energy, aerospace and other fields are also extremely powerful, not to mention energy, light nuclear fusion and heavy nuclear fusion technology has been completely broken through, the energy density of the battery has reached 6.8 kWh/kg, almost 20 times that of the real world.

But even so, before the planetary engine was put into use, there was still a shortage of energy for mankind.

There are 12,000 planetary engines, and each engine costs up to 100 billion dollars.

One of the most important is the issue of raw materials.

Even Pang Xuelin himself couldn't believe it when he saw the relevant data.

More than 90 percent of the main structure of a planetary engine is made of steel, and the mass of each planetary engine is as high as 500 million tons, which can burst out nearly 15 billion tons of thrust. (Note: There is a loophole here, under normal circumstances, such a thrust cannot push the earth away from the solar system, but in the original book, it will not be changed)

A full twelve thousand engines and dungeons, almost beyond the limits of human industry.

In order to escape the solar system, in order to survive under this starry sky, this desperate race exploded with unimaginable power.

More than 90 percent of the world's five billion people, except for the elderly, children and students, are directly or indirectly contributing to the construction of planetary engines.

For thirty years, the coalition government has been throwing all its resources into the construction of planetary engines at all costs, mobilizing the whole population.

Ninety percent of the electricity generated by the nuclear fusion power station is used to build planetary engines.

If there is not enough iron ore on the earth, they will dig on the moon, and if there is not enough iron ore on the moon, human beings will send spacecraft to the asteroid belt to find metal-rich asteroids, and after finding them, they will install engines on them and transport them back to Earth.

The remaining electricity can only barely ensure the electricity consumption of large-scale fully enclosed farms and people's livelihoods.

For example, private electric vehicles, which consume more electricity, are strictly prohibited, and even ordinary computers and mobile phones and other electronic products are so high that ordinary people can hardly reach them.

Therefore, the world in the field of microelectronics is not much different from the previous life, materials science is also strong in metallurgy, etc., there is almost no special breakthrough in the field of non-metallic materials.

Graphene is barely produced, but it is unsatisfactory in terms of purity and cost.
