This materials science should belong to materials science. ”

Yu Sheng thought secretly.

"There are a lot of courses involved in materials science, such as political theory, which is an indispensable subject in many disciplines, and this is a foreign language, if you don't learn a foreign language well, you can't understand many things at all."

"The second is the most important physics and chemistry, there is such a saying in science, learn mathematics, physics and chemistry, and you are not afraid to go all over the world."

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

This statement is very true to some extent.

However, if he wants to help Wu Zeqing, he must understand what is here, if he doesn't understand it, then he has no way to continue.

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

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

"Yes." System Channel.

"Can I study materials science?" Yu Sheng's eyes twinkled, and he asked.

"No, you can't." The system explained lightly: "The host can learn one of the subjects. ”

"I'll ...... So dark? ”

When Yu Sheng heard this, his face turned dark.

"There are a lot of things in the materials discipline, and the host can choose one of them to be proficient in."

When he heard the words for the rest of his life, he groaned slightly.

There are about 12 main courses in materials science, and if you want to learn them well, you can only come step by step.

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

"Didi, the host learns math and is proficient."

When the sound of the system resounded, Yu Sheng was shocked, and for a moment, he felt that there was a lot of math in his head.

After feeling this knowledge for the rest of his life, Rao couldn't help but gasp for the rest of his life.

This mathematical mastery is not as simple as the mathematical mastery on the earth, and he feels that his mathematical mastery is completely worthy of being a master.

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

This made Yu Sheng more and more excited, and 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 on physics and chemistry in these books. ”

"How much does it cost?" When Yu Sheng heard this, he looked overjoyed and asked excitedly.

"1 point of military merit is worth a copy." System Channel.

"So little?" When Yu Sheng heard this, he was slightly stunned.

Immediately, Yu Sheng thought of something, and said with some anger: "You are a cheating father, right?" I bought chess proficient before, but I spent a full 200 military merit points, you tell me now, 1 military merit is worth a copy, is this cheating me? ”

"This is a little different from chess skills, whether it is physics or chemistry, there are a lot of books in it, each of these books is different, the host is to read 200 books, and may not be able to master it, which is why books are so cheap."

"Of course, the price of different books is different."

"As for those drawings, it's a different price, after all, the drawings are someone else's research results."

After hearing this, Yu Sheng's face turned dark, although the system was a bit pitted, but ...... That's right.

There are many books about chemistry and mathematics, and these books cannot be read in a person's life, in his whole life, even if he consumes all his military merits, he may not be able to finish learning.

It can be seen how many books there are.

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

Physical chemistry and the like, the way of thinking is very important, this thing can't be copied step by step, if it's the history of the ground or something, these things are dead, you copy and copy, it's not a big problem.

But......

This thing definitely doesn't work.

Because it's so flexible, you copy it, and it's eighty percent 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 learned, give me a hundred copies of what I have not learned, and those related to materials." ”

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

"Sure." The rest of the life.

"Didi, the host purchase is successful."

After buying these things, the rest of his life felt that he had a lot of knowledge in his head, and this knowledge seemed to be innate, when these things poured into his mind, he did not feel a headache for the rest of his life, 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, and 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 such as material bases and collective names...... Let's have fifty copies, fifty should be enough to read, right? ”

"That's enough." System Channel.

"Then let's have fifty copies." Thinking of this, the rest of my life had a pain in my flesh.

"The Didi host buys four hundred books, and it needs to consume four hundred military merit points, do you want to continue?"

"So much?"

After Yu Sheng heard this, he gasped, full of shock.

"Yes." The system replied faintly.

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

"Didi, the host purchase is successful."

As the sound of the system fell, Yu Sheng looked at his military merit value, which was 730 points before, but at this time, he directly consumed 600 points, leaving 130 points.

At that time, the chess skill consumed 200 points for him, which was considered a waste of money, after all, he won the martial dragon god, and the system rewarded him with another 200 points.

It's just that there are more than 100 left after more than 700, which makes the rest of my life have a toothache, and so many military merit points are gone.

The military merit value is still not spent......

Even if he helped Lao Wu solve this problem this time, he would only be three hundred and three, no matter how you look at it, it will be a blood loss.

Yu Sheng took a deep breath.

After this knowledge enters his own brain, it is his own, and this knowledge directly enters his brain, and it will also allow him to understand it, which is the power of the system.

Overall, it's not too much of a loss.

After all, in the army, too, there are institutes.

As long as it is related to national construction, it is basically counted.

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

You must know that people read a number of books in this life, and it is impossible to read all books, and it is impossible to read one book a day, especially a book similar to this.

If you can read one in half a month, it's pretty good.

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

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

For now, the rest of his life is no worse than those professors.

As long as he is willing to come up with a few thousand books for the rest of his life, he can even become an academician.
