But Pang Xuelin can't say these words now.

He is just a fifteen-year-old high school student, and no one cares about his thoughts.

Not to mention, all this was just his guess, and he was not sure whether it would happen in the end.

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 head teacher.

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

But when Pang Xuelin easily finished several sets of Imo competition test papers and scored all of them, they had nothing to say.

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

Pang Xuelin agreed immediately.

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

With Pang Shaoan's relationship, it shouldn't be too simple to have a hearing in Jiangda.

Especially after Pang Xuelin took out his middle school grade certificate and various award certificates, the vice 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 Da can directly recruit students and don’t have to participate in the college entrance examination.

Pang Xuelin didn't care too much about this, and his scores in other subjects were not bad. When he was taking the college entrance examination in the real world, he got 728 (total score 810), which was more than 20 points higher than the score line of Tsinghua and Peking University. If it weren't for his grandfather's relationship, he wouldn't have chosen Jiangda at all.

What he next has to do is to show his abilities as quickly as possible, lay a solid foundation, and then find a suitable opportunity to take out the flying blade material and graphene aerogel metamaterial.

There are many things to learn in the materials science major, so there is no need to mention basic courses, including physical chemistry, material chemistry, analytical chemistry, organic chemistry, polymer chemistry, material physics, material mechanics... Each course requires a lot of energy.

Pang Xuelin found a course schedule for undergraduate materials majoring, listed the professional course time one by one, and then formulated his own study plan.

With the hearing of Jiang University, you can take the experimental class and apply for a library library loan certificate and canteen meal card. Except for the inability to take the exam to get credits, Pang Xuelin is no different from an ordinary Jiang University student.

Moreover, there is also a computer in the library, so Pang Xuelin can access the Internet here to obtain information from all aspects.

Next, Pang Xuelin rode his bike to take Yao Bingxia to school every morning, and then went to Jiangda University. If there was no class in the morning, he would appear in the library on time, and wait until the afternoon class was over before taking Yao Bingxia home.

Pang Xuelin seemed to have returned to his old high school days, and he had endless books and endless exercises every day.

He was very grateful to the study habits he had cultivated for him since childhood. Good study habits and hard work, Pang Xuelin's name soon spread to the teachers of the School of Materials.

The teachers in almost every class have encountered the scene of being stopped by Pang Xuelin after class and asking questions.

For this studious boy, they naturally do not hesitate to answer the questions.

Pang Xuelin is like a dry sponge, absorbing all aspects of materials science knowledge hungrily.

Although most of his energy has been devoted to mathematics over the years, the foundation of physics and chemistry is there, and with many years of learning experience, Pang Xuelin quickly gained a relatively systematic understanding of materials science.

At least the papers on flying blade materials and graphene aerogel metamaterials have been confused at the beginning, but now they have gradually seen the trick.

...

Two months passed in a flash.

In September, Pang Xuelin represented Jiangcheng Middle School in the National High School Mathematics Competition, and without surprise, he won full marks and was successfully selected for the Chinese High School Mathematics Olympic Winter Camp.

It’s just that the winter camp will not open until December, and it’s still early.

Moreover, Pang Xuelin has decided not to go to the winter camp and training team. Anyway, he only does exercises and various training every day, which means nothing to him.

As for how to get the teacher in the winter camp to agree, this is even more no problem. You only need to get a few sets of imo test papers, spend some 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.

Due to the solar crisis, the technology tree in this world seems to be a bit crooked.

This is a world with highly developed heavy industry.

Heavy industry accounts for more than 90% of GDP.

Engineering technology has reached its peak, otherwise it would be impossible to create a behemoth like a planetary engine.

In addition, metallurgy, energy, aerospace and other fields are also extremely powerful. Needless to say, energy has been completely broken through, and the energy density of the battery has reached 6.8 kilowatt-hours/kilogram, almost twenty times that of the real world.

But even so, before the planetary engine is activated, humans still have the problem of insufficient energy.

For 12,000 planetary engines, the construction cost of each engine is as high as one trillion US dollars.

The most important one is the issue of raw materials.

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

More than 90% 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 are loopholes here. Under normal circumstances, such thrust cannot push the earth away from the solar system, but this is the case in the original work, so it will not be changed)

A total of 12,000 engines and dungeons almost exceeded the limits that human industry could achieve.

In order to escape from the solar system and to continue to survive under this starry sky, this desperate race burst into unimaginable power.

More than 90% of the remaining humans, except for the elderly, children and students, are directly or indirectly serving the construction of planetary engines.

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

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

If there is not enough iron ore on the earth, I will dig it on the moon. If there is not enough on the moon, humans will send spacecraft to the asteroid to take it to find metal-rich asteroids. After finding it, they will install engines on it and transport it back to the earth.

The remaining electricity can only barely ensure large fully enclosed farms and people's livelihood electricity.

Private electric vehicles that consume more electricity are strictly prohibited. Even ordinary computers, mobile phones and other electronic products are priced so high that ordinary people cannot reach.

Therefore, the world is not much different from its previous life in the field of microelectronics, and materials science is also strong in metallurgy, and there are almost no particularly big breakthroughs in the field of non-metallic materials.

Graphene is barely produced energy, but it is difficult to satisfy both purity and cost.
