I have a commando system

This materials science should belong to materials science."

Yu Sheng secretly thought.

"Materials science involves many courses, such as political theory courses, which is an indispensable subject in many subjects. In this case, it is foreign language. If you are not good at foreign languages, you will not be able to understand many things."

"The second most important thing is physics and chemistry. There is a saying in science, if you learn mathematics, physics and chemistry, you will not be afraid of traveling all over the world."

It can be said that everything is closely related to mathematics, physics and chemistry.

This sentence is very correct to some extent.

However, if he wanted to help Wu Zeqing, he had to understand the things inside. If he didn't understand, then he wouldn't be able to continue.

"By the way, system, I remember I also have a skill mastery."

At this moment, Yu Sheng suddenly thought of something and asked hurriedly: "System, can I still use this mastery skill?"

"Okay." The system said.

"Then can I study materials science?" Yu Sheng asked with his eyes twinkling.

"No." The system explained calmly: "The host can learn one of the subjects."

"I'll go...is it so dark?"

When Yu Sheng heard this, his face darkened.

"The subject of materials includes many things, and the host can choose to be proficient in one of them."

After hearing the words for the rest of my life, I pondered for a while.

There are about twelve main courses in materials science. If you want to learn them well, you can only take them step by step.

Thinking of this, Yu Sheng said: "System, add skill proficiency to mathematics."

"Didi, the host has learned mathematics and is proficient in it."

When the sound of the system resounded, Yu Sheng was shocked all over. For a moment, he felt that there were many more mathematical things in his mind.

After Yu Sheng experienced this knowledge, Yu Sheng could not help but take a breath of cold air.

This mathematical proficiency is not as simple as the mathematical proficiency on earth. He feels that his mathematical proficiency can be called a master.

It can be seen that the system classification is also very strict.

This made Yu Sheng more and more excited. Yu Sheng hurriedly said: "System, is there anything about physics and chemistry in the mall?"

"Yes." The system explained: "The host has read a lot of books before, and there are many books about physics and chemistry in these books."

"How much does it cost?" Yu Sheng looked overjoyed and asked excitedly after hearing this.

"One point of military merit is worth one book." The system said.

"So few?" Yu Sheng was slightly startled when he heard this.

Immediately, Yu Sheng thought of something and said angrily: "Are you cheating me? I bought Chess Master before, but I spent a total of 200 points of military merit. You tell me now that 1 point of military merit is worth one book.

Are you trying to trick me?"

"This is a little different from chess skills. Whether it is physics or chemistry, there are many books in it. Each of these books is different. Even if the host reads 200 books, he may not be able to master it. This is why books

That’s why it’s so cheap.”

"Of course, the prices of different books are also different."

"As for those drawings, they have a different price. After all, the drawings are the research results of others."

After Yu Sheng heard this, his face darkened. Although the system was a bit flawed, but... that's right.

There are many books on chemistry and mathematics. These books can never be finished by a person in his lifetime. Even if he consumes all his military merit points, he may not be able to finish them.

This shows how many books there are.

However, reading a lot of books is not of much use. The most important thing is the way of thinking.

For things like physical chemistry and the like, the way of thinking is very important. You can't copy it step by step. If it's about field history and the like, these things are dead. If you just copy them, it won't be a big problem.

But……

This thing absolutely won't work.

Because it is too flexible, if you copy it, you will probably be wrong.

"Then study physics and chemistry."

Thinking of this, Yu Sheng's eyes flickered and he immediately said: "System, I have also studied chemistry and physics before. Forget what I have studied. Give me the ones I have not studied and those related to materials.

One hundred copies."

"Didi host spent 200 military merit points to buy physics and chemistry books. Are you sure?"

"OK." Yu Sheng said.

"Didi, the host purchase was successful."

After buying these things, Yu Sheng felt that there was a lot more knowledge in his mind. This knowledge seemed to be innate. When these things poured into his mind, Yu Sheng did not feel a headache at all. On the contrary,

, he felt as if this knowledge had existed in his mind before.

Now, it's just a sudden recollection.

This made Yu Sheng a little surprised. I have to say that the system did a very good job in this regard.

Yu Sheng thought for a while and said: "System, by the way, buy some other books on basic materials and general titles... Let's get fifty books. Fifty books should be enough, right?"

"That's enough." The system said.

"Then let's get fifty books." Thinking of this, my body ached for the rest of my life.

"Didi host purchases 400 books, which will cost 400 military merit points. Do you want to continue?"

"so much?"

After hearing this, Yu Sheng took a deep breath and said in shock.

"Yes." The system responded calmly.

"Buy it." Yu Sheng gritted his teeth and said with a bit of pain in his balls.

"Didi, the host purchase was successful."

As the sound of the system fell, Yu Sheng looked at his military merit points. It was 730 points before. Now, he directly consumed 600 points, leaving only 130 points.

At that time, his chess skill consumed 200 points, so it was considered free. After all, he defeated Wu Long Shen, and the system rewarded him with another 200 points.

However, there are now more than 100 left from more than 700, which makes Yu Sheng feel a bit toothache, so much military merit is just gone.

You can’t help but spend military merit...

Even if he helps Lao Wu solve this problem this time, he will only have three hundred and three dollars, which is a loss of blood no matter how you look at it.

Yu Sheng took a deep breath.

After this knowledge enters his mind, it becomes his own. Moreover, this knowledge enters his mind directly and allows him to understand it. This is the power of the system.

Overall, it’s not too bad.

After all, there are also research institutes in the military.

As long as it's related to national construction, it basically counts.

Yu Sheng digested these six hundred books. After Yu Sheng finished digesting them, a light of wisdom flashed across Yu Sheng's eyes.

You must know that people read a lot of books in their lifetime. It is impossible to read all books, and it is impossible to read one book a day, especially a book like this.

If you can read one book every half a month, it’s pretty good.

This is equivalent to reading twenty or thirty books a year. Of course, some books are simple and easy to understand, and you may be able to read them in three to five days.

But the books the system selected for him were all very difficult.

For now, Yu Sheng will be no worse than those professors.

As long as he is willing to produce thousands of books for the rest of his life, he can even become an academician.
