The First Order

In the morning, Ren Xiaosu was reading in the library, while An Yuqian was sitting at the door of the library, leaning on a chair and sleeping.

If sunlight shines on An Yuqian's face from outside the door, An Yuqian will buckle the book on his face to block the light.

When Ren Xiaosu came every morning, he would consciously shoot An Yuqian for ten yuan, and An Yuqian did not have to call Ren Xiaosu anymore. He yawned at the door at 8:30 every morning.

Gradually, An Yuqian felt that old was so uncomfortable. He used to play mahjong all night, and then took a good night's sleep at home.

When the one named Ren Xiaosu came, he could only sleep on a chair in the library!

Can you sleep on the bed comfortably?

While no one was in the library, An Yuqian specially observed what book Ren Xiaosu was reading, but he almost laughed and died. He turned out to be a high school math, physics, and chemistry textbook!

Ren Xiaosu insisted on coming to the library for so many days, and finally let An Yuqian look at him a little bit. An Yuqianxin said that the library finally came to a good learning, but the result was reading a high school textbook.

How can he be a senior in his senior year?The co-author is a poor student who starts from zero?

An Yuqian broke his finger and counted for a while, and there were only three months left before the college entrance examination. Is it too late for the tuition in high school?

Regardless of An Yuqian walking around, Ren Xiaosu didn't even look up at him.

An Yuqian couldn't help it: "You are a little late to make up the class now, three months away from the college entrance examination!"

Ren Xiaosu looked up at him: "I don't take the college entrance examination."

"Don't take the college entrance examination? Then what kind of physics and chemistry do you study in high school?" An Yuqian was shocked. "Don't you go to the factory after graduation, what's the use of learning this stuff."

"Knowledge is useful, the knowledge you learn is your own," Ren Xiaosu said calmly.

An Yuqian shrugged his shoulders and turned away: "Don't forget to go before breakfast every day. If it weren't for you, I wouldn't have to eat breakfast at all. It's because of the extra cost because of you..."

"Got it," Ren Xiaosu said.

However, An Yuqian suddenly discovered that, in addition to Ren Xiaosu, there were actually a group of students who suddenly looked at the book in the afternoon.

There are more than 20 male and female students in total, and sitting in the library for an afternoon, for several days.

You should know that although some people have read books in the past afternoon, it will not be so frequent and stable, and the number will be so neat.This group of students... was sitting next to Ren Xiaosu in an organized and disciplined way.

An Yu woke up in the afternoon before waking up and found that Wang Yuchi and others were reading mechanical manufacturing related books, which had long exceeded the high school outline.

When the library closed, Wang Yuchi suddenly said to Ren Xiaosu: "Squad leader, should we close the door and go home?"

An Yu was stunned on the spot. Was this young boy who gave him breakfast every day even the monitor of this group of students?Ordinary students learn things beyond the syllabus, the class leader self-taught high school?

What a mess...

Ren Xiaosu looked up at the sky: "You come back first, I will look at it for a while."

"Hey," An Yu couldn't sit still in front of her: "I should leave work now, you know!"

"Give you 50!" Ren Xiaosu said without lifting his head.

An Yuqian was not happy: "That won't work either. I should go to play mahjong. Tonight I might be able to make a copy!"

Ren Xiaosu quietly put the book back on the shelf, turned around and left.

The next morning when Ren Xiaosu saw An Yuqian, the first sentence was: "Have you turned the book?"

"Why is your child's mouth so broken," An Yu's front tooth hurts: "Is this what you should ask?"

"That's a loss," Ren Xiaosu patted An Yu for the first ten dollars: "Go for breakfast."

An Yuqian held ten dollars in his hand and felt insulted...

In the afternoon, when Wang Yuchi came back, An Yuqian suddenly sat opposite, Ren Xiaosu looked up at him in surprise: "What's the matter?"

An Yuqian said: "You are in the knowledge of the main complement machinery manufacturing, but you read the wrong book!"

Ren Xiaosu frowned, he glanced at the book in the hands of Wang Yuchi and others: "What should I do?"

Without the teacher's instruction, they could only go forward with the stones crossing the river, and the progress was extremely slow.

Although Jiang Wu is a teacher, Jiang Wu is a Chinese teacher...

At this time An Yuqian said: "500 yuan, I tell you what to watch!"

As soon as the words fell, Ren Xiaosu threw 500 yuan over, and Wang Yuchi whispered next to him, "Squad leader, how do I feel like a liar?"

Ren Xiaosu shook his head: "Cheaters won't even have breakfast money."

An Yuqian almost yelled and yelled. This is to insinuate that he is not even qualified to be a liar!

An Yuqian sneered and said, "If you want to learn mechanics in a system, don't want to learn how to run before you learn to walk. You have to learn math and physics first!"

Ren Xiaosu leaned on the back of the chair and listened silently, while Wang Yuchi and others had begun to open the book and were ready to take notes.

"I suggest that you first look at "Mathematical Analysis" written by Chen Jixiu as an introduction, and then linear algebra is a must. This is not enough for you in high school courses."

"Don't read "Pu Wu"," An Yuqian threw a book on the table: "Just look at this Feynman handout."

"Real analysis...Forget it, don't look at this first."

"As for the mathematical physics method, it depends on Wang Dexin's. Everyone's talk is basically real variable functions, special functions, mathematical equations and the like, there is not much difference."

"You need to watch it."

"You also have to look at electrodynamics."

An Yuqian talked eloquently for half an hour. Ren Xiaosu felt that it had been several years since he learned this set. As a result, An Yuqian said: "This is just just getting started. I want to really involve You are still far away to the deep machinery manufacturing!"

Ren Xiaosu understands that co-authoring this product is coming fast...

However, Ren Xiaosu suddenly realized that this An Yu was not an ordinary person. Even if he was a liar, I am afraid he would not carry so many things in order to earn 500 yuan. The key is that no one can teach him to recite.

Ren Xiaosu looked at An Yuqian and said, "You come to teach them, and I will pay you 500 per lesson."

An Yuqian's eyes lit up, but the result was immediately reserved: "My time is precious..."

"400."

"Hey, why are there fewer and fewer!"

"300."

"I teach! 500! You can't miss a penny!"

Ren Xiaosu just laughed: "If you don't teach well, I won't pay."

"I can't teach you well?" An Yuqian's eyes widened: "I'm An Yuqian...Forget it, you don't understand after telling you!"

It's just that An Yuqian suddenly felt that the teenager in front of him might be more complicated than he thought. Who would pay 500 yuan for the last class?

...

The fourth is to make up for yesterday.

Push a friend's book, the author of Yuzuzhai's new work "The Lord of the Dragon King"

Introduction: Super beast warriors who have turned over rivers and rivers are drowned in the long river of history.

The mechanical civilization rises in the siege of the sand worms.

The once dragon warrior has disappeared, and now the god mech protects human civilization.

Zhang Qingyang and the arrogant cat inadvertently embarked on a long march to find a beast civilization... (The above recommended 200 words will not be charged extra.)
