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

If the sunlight shines on An Gozen's face from outside the door, An Gozen will also deduct a book on his face to block the light.

Every morning when Ren Xiaosu came, he would consciously shoot ten yuan for An Yuqian, and An Yuqian didn't need Ren Xiaosu to call and urge, and waited at the door at half past eight every morning with a fixed yawn.

Gradually, An Yuqian felt very uncomfortable like this, he used to play mahjong all night, and then sleep well at home in the morning.

As a result, after the person named Ren Xiaosu came, he could only sleep on a chair in the library!

Can you sleep comfortably in a bed when you are on a chair?

Taking advantage of the fact that there was no one in the library, An Yuqian specially observed what Ren Xiaosu was reading, but he almost died of laughter, it turned out to be a high school mathematics, physics, and chemistry textbook!

Ren Xiaosu insisted on coming to the library for so many days, and after all, An Yuqian was a little impressed, and An Yuqian said that this library finally came to be studious, but it turned out that he was reading a textbook for the first year of high school.

Looking at Ren Xiaosu's age, why do you have to be in the third year of high school?

An Yuqian snapped his fingers and calculated, there are only a few months left before the college entrance examination, is it too late to cram for the first year of high school now?

Letting An Yuqian wander around, Ren Xiaosu didn't even look up at him.

An Yuqian couldn't help it: "You're a little late to make up classes now, it's only three months before 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 are you studying mathematics, physics and chemistry in the first year of high school," An Yuqian was shocked: "Won't you go to the factory after graduation, what's the use of learning this thing." ”

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

An Yuqian shrugged his shoulders and turned to leave: "Don't forget to do it every day before breakfast, if it weren't for you, I wouldn't have to eat breakfast at all, this cost is because of you......"

"Got it," Ren Xiaosu said.

However, An Yuqian suddenly found that in addition to Ren Xiaosu, there was actually a group of students who suddenly couldn't move to read in the afternoon.

There must be more than 20 male and female classmates combined, and they sat in the library for an afternoon for several days in a row.

You must know that although there are people who come to read books in the past afternoons, they will not be so frequent and stable, and the number is so neat. This group of students ...... actually sat next to Ren Xiaosu in an organized and disciplined manner.

After waking up in the afternoon, An Yuqian leaned over to take a look, and found that Wang Yuchi and others were reading books related to mechanical manufacturing, which had long exceeded the syllabus of high school.

When the library was closing, Wang Yuchi suddenly said to Ren Xiaosu: "Squad leader, it's time to close the door and go home, right?"

An Yuqian was stunned on the spot, this young man who gave him breakfast money every day was still the class leader of this group of students? Ordinary students learn things that exceed the curriculum, and the class leader teaches himself the first year of high school?

What a mess is this......

Ren Xiaosu glanced up at the sky: "You go back first, I'll look at it later." ”

"Hey," An Yuqian couldn't sit still, "I should get off work, you know!"

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

An Yuqian was not happy: "That's not good, I should go play mahjong, maybe I can turn the book tonight!"

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

The next morning, Ren Xiaosu's first words before seeing An Yu were: "Have you turned the book?"

"Why is your kid's mouth so broken," An Yuqian had a toothache, "This is what you should ask?"

"That's the loss," Ren Xiaosu patted An Yu for ten yuan: "Let's have breakfast." ”

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

In the afternoon, when Wang Yuchi and the others came again, An Yuqian suddenly sat opposite, and Ren Xiaosu looked up at him in surprise: "Something?"

An Yuqian said: "You are mainly supplementing the knowledge of mechanical manufacturing, but you are reading the wrong book!"

Ren Xiaosu frowned, he glanced at the book in the hands of Wang Yuchi and others: "Then how should I look at it?"

Without the teacher's guidance, they can only grope forward like crossing the river with stones, and the progress is extremely slow.

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

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

As soon as the words fell, Ren Xiaosu threw five hundred yuan over, and Wang Yuchi whispered beside him: "Squad leader, how do I feel that he is a liar?"

Ren Xiaosu shook his head: "A liar won't even have breakfast money. ”

An Yuqian almost scolded, this is to insinuate that he is not even qualified to be a liar!

An Yuqian sneered and said: "If you want to learn machinery systematically, don't want to learn others to run before you learn to walk, you have to learn mathematics and physics first!"

Ren Xiaosu leaned back in the chair and listened silently, while Wang Yuchi and the others had already begun to open the book and prepare to take notes.

"I suggest you first read Chen Jixiu's "Mathematical Analysis" as an introduction, and then linear algebra must be learned, which you don't learn enough in high school courses. ”

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

"Real Analysis...... Forget it, you don't need to look at this yet. ”

"As for mathematical and physical methods, it depends on Wang Dexin, everyone basically talks about real variable functions, special functions, mathematical equations and the like, and there is no big difference. ”

"You have to see it. ”

"You have to look at electrodynamics too. ”

An Yuqian talked endlessly for half an hour, Ren Xiaosu felt that it would take several years to learn this set, but An Yuqian smashed it at this time and said: "This is just getting started, if you want to really involve profound mechanical manufacturing, you are still far away!"

Ren Xiaosu understood that co-authoring this product was a quick deal......

However, Ren Xiaosu also suddenly realized that this An Yuqian is not an ordinary person, even if he is a liar, I am afraid he will not carry so many things in order to earn 500 yuan, and the key is that no one can teach him to memorize.

Ren Xiaosu looked at An Yuqian and said, "You come to give them a lesson, and I will pay you 500 for a lesson." ”

An Yuqian's eyes lit up, but he immediately became reserved: "My time is precious......"

“400。 ”

"Hey, why is there less and less!"

“300。 ”

"I'll teach!500! Not a penny less!"

Ren Xiaosu laughed at this time: "If you can't teach well, I won't pay." ”

"Can I teach it?" An Yuqian's eyes widened: "I An Yuqian...... Forget it, I told you that you don't understand!"

It's just that An Yuqian suddenly felt that the young man in front of him was probably more complicated than he imagined, who would pay 500 yuan for an ordinary student to take a class?

......

Fourth, it is even more to make up for yesterday.
