i have a special forces system

This material science should belong to material science. "

Yu Sheng thought secretly.

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

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

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

To some extent, this sentence is very true.

However, if he wants to help Wu Zeqing, he must understand what's inside. If he doesn't understand, then he has no way to continue.

"By the way, system, I remember that I still have a skill to master."

At this moment, Yu Sheng suddenly thought of something, and hurriedly asked: "System, can this skill be mastered?"

"Yes." The system said.

"Then can I study material science?" Yu Sheng asked with bright eyes.

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

"I'm going...it's so dark?"

When Yu Sheng heard this, his face darkened.

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

After Yu Sheng heard the words, he pondered for a while.

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

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

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

When the sound of the system resounded, Yu Sheng was shocked. For a moment, he felt that there were a lot of things about mathematics in his mind.

After Yu Sheng finished feeling the knowledge, Rao Yu Sheng couldn't help but gasp.

This mathematics proficiency is not as simple as the mathematics proficiency on earth. He feels that his mathematics 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 is it?" Yu Sheng asked excitedly when he heard the words.

"1 point of military merit is worth a book," the system said.

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

Immediately, Yu Sheng thought of something, and said angrily, "Are you cheating? I bought Chess Proficiency before, but it cost me 200 points of military merit. Now tell me, 1 point of military merit is worth a book. Is this cheating on me?"

"This is a bit 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 them. This is why books That's why it's so cheap."

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

"As for those blueprints, it is another price. After all, the blueprints are the research results of others."

After hearing this, Yu Sheng's face darkened. Although the system is a little tricky, but...it's true to say so.

There are a lot of books on chemistry and mathematics, these books, a person can never finish reading them in his whole life, even if he consumes all his military merit points, he might not be able to finish them.

It can be seen how many books there are.

However, how much you read is not of much use. The most important thing is the way of thinking.

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

but……

This thing will never work.

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

"Then study physics and chemistry."

Thinking of this, Yu Sheng's eyes flickered for a moment, and he said immediately: "System, I have studied chemistry and physics before, so let me forget what I have studied, and give me the ones that I have not studied, and those related to materials." One hundred copies."

"The Didi host consumes 200 points of military merit to buy physics and chemistry books, are you sure?"

"Sure." Yu Sheng said.

"Didi, the host has been purchased successfully."

After buying these things, Yu Sheng felt that there was a lot of knowledge in his mind, which seemed to be innate. When these things flooded into his mind, Yu Sheng didn't feel a little headache, on the contrary , he felt as if the knowledge had been stored in his mind before.

Now, it's all just a sudden memory.

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

Yu Sheng thought for a while and said, "System, by the way, buy some other books on the basis of materials and collective names... Let's come to fifty books one after another. Fifty books should be enough to read, right?"

"Enough." The system said.

"Then let's get fifty copies." Thinking of this, Yu Sheng felt a pain in his flesh.

"The Didi host needs to consume [-] points of military merit to buy [-] books. Do you want to continue?"

"so much?"

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

"Yes." The system responded lightly.

"Buy it." Yu Sheng gritted his teeth and said with some pain.

"Didi, the host has been purchased successfully."

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

At that time, his chess skills consumed 200 points, which was considered a waste. After all, he won the Wulong God, and the system rewarded him with another [-] points.

It's just that there are more than 700 and now there are more than 100 left, which makes Yu Sheng a little bit toothache. So many military merit points are gone.
