In the library of Huaxia University, it is very quiet, and everyone is immersed in the ocean of knowledge.

On Qin Yi's seat, Qin Yi finished turning the last page of a book, stretched his waist slightly, and put down this "Introduction and Appreciation of Chinese Painting", next to Qin Yi, dozens of books were piled high, this was just the book that Qin Yi finished reading in the morning.

The genetic optimization liquid is very powerful, Qin Yi's brain has been developed, his reading ability and memory are simply off the charts, ten lines at a glance, never forget, reading a book is a matter of a few minutes, and this is Qin Yi leaving some time in his mind to summarize and recall the knowledge and content he has read.

If he just memorized and learned these contents and knowledge, Qin Yi would read books faster, of course, he came to read books to gain knowledge, not to compete with anyone to turn the book.

"It's almost 12 o'clock, well, it's time to go to dinner, and bring a few books back to look good when you take a break at noon."

Qin Yi looked at the time, the time of the morning passed in a flash, and when he was really immersed in something, time passed so fast.

Picking up the books on the table, Qin Yi began to put these back into the distance, and at the same time began to look for new books to borrow and read.

"I have a 2-hour break at noon, I take a half-hour nap, eat for half an hour, and there is another hour in between, and at the speed at which I read books, I have to borrow at least 5 books to take back to read."

Qin Yi was planning carefully in his mind, and he didn't notice at all that next to Qin Yi, a beautiful woman was looking at him with puzzled eyes at this time.

"Is this man sick?"

"I spent the morning constantly flipping through books here, and I flipped through dozens of books in the morning."

Wen Xueying looked at Qin Yi like a monster, and then looked at the tall books piled up on Qin Yi's desk, this was the first time she had encountered such a strange person.

"It's not good to come to the library to read good books, but I specialize in flipping books to play, how boring this person is, high school mathematics, high school physics, high school chemistry....... and oil painting introduction and appreciation."

Because her seat was next to Qin Yi, she didn't notice Qin Yi at the beginning, but when she saw Qin Yi next to her when she was resting, she began to notice Qin Yi.

After carefully looking at the books Qin Yi was reading, she was even more sure that the person next to her was really sick, and he was not lightly ill, and he actually came to the library to flip through the books and play, which had reached the point of being hopeless.

"Wait a minute, I'm going to test him, such a person should be expelled from the library, occupying the resources of the library, even playing with books here, and thinking of himself as a child who has just learned to speak?"

Wen Xueying looked at Qin Yi who was holding a pile of books and gradually walked away to return the books, she picked up a book from Qin Yi's table, and explained the advanced mathematical functions and limits in detail.

She quickly copied a question from the book, and was about to ask Qin Yi for the answer to this question when she was about to wait, but she decided to embarrass Qin Yi and make this person who occupied the library resources and flip through books never dare to come to the library again.

"Hmph~ Forget it if you don't see it, since I met it, I don't want to teach you a good lesson, you really think of this place as a kindergarten."

Wen Xueying carefully looked at the question she had just copied down, and was slightly stunned, she couldn't even answer this question for a while.

"No, I have to answer the answer first, otherwise I won't be able to answer it if he asks back."

"It's just that this question is the content of functions and limits, and I forgot how to solve it for a while, as if I had seen this question once when I was doing the postgraduate examination questions in previous years."

Wen Xueying frowned suddenly, took her pen and began to calculate on the scratch paper, the more she calculated, the more she frowned, because she couldn't figure it out.

Soon, Qin Yi walked back with a few books, put down a few new books, and picked up some other books that had already been read and prepared to return them.

"This classmate~"

Wen Xueying whispered to Qin Yi.

"Hello, what's the matter?"

Qin Yi turned around and looked over, and a beautiful and delicious face came into view, I have to say that Wen Xueying is as good as her name, her skin is as fair as snow, and she can be broken by blowing.

In the front, Qin Yi had been concentrating on reading, and he didn't notice that there was such a beautiful woman beside him, and he was slightly stunned when he saw the other party looking for him.

"I see you've just been reading a book on high number functions and limits, and I just happen to have a topic here that won't be wrong, I wonder if you can please give me some advice?"

Wen Xueying took out the topic she had already fried and said.

"Okay, I'll take a look~"

Qin Yi nodded, picked up the topic and looked at it.

If x→0, (1-ax^2)^1/4-1 and xsinx are equivalent infinitesimals, then a = how much.

"Quite simply, a equals -4."

As soon as Qin Yi saw the question, he instantly calculated the answer to this question, and almost blurted it out without thinking.

"How do you know that a is equal to -4, you write me the calculus."

Wen Xueying was slightly stunned when she heard this, and then said with some disbelief.

Qin Yi smiled, picked up the process of writing the answer on the scratch paper.

（1-ax^2）^1/4-1=1-1/4*ax^2+o(x^2)-1=1/4*ax^2+o(x^2); So, xsinx=x^2+o(x^2), therefore: a=-4

There was almost no pause, and Qin Yi quickly wrote out the process of solving this problem.

"You see, is it equal to -4, this problem is a very typical function, limit problem, very simple."

Qin Yi pushed the scratch paper in front of Wen Xueying, smiled and said.

Wen Xueying carefully looked at the derivation process on the scratch paper, and immediately made it clear, this topic is not difficult, she can solve it after learning high mathematics, just now she also forgot some content for a while, so she didn't solve it, now read Qin Yi's draft, and naturally understand it immediately.

"It's still -4, it seems that I still have some misunderstanding about you."

Wen Xueying looked at it carefully, and suddenly felt that her face was slightly red, and said with some embarrassment.

"Misunderstanding? It seems like we're meeting each other for the first time. ”

When Qin Yi heard this, he was confused, and he was a little confused.

"That's right, I've been sitting next to you all morning, I see that you've been here all morning and keep flipping books, and I thought you were just here to flip books."

Wen Xueying smiled and said embarrassedly, originally wanted to directly say that she thought Qin Yi was sick, but after thinking about it, she changed her words.

"Ah, that's right, I didn't bother you, did I?"

When Qin Yi heard this, he immediately smiled awkwardly, and asked a little embarrassedly, thinking that because he kept flipping books, it affected the other party's learning.

"No, no, I'm just a little curious, you read so fast, can you remember the knowledge and content of the book?"

Wen Xueying hurriedly shook her head and asked with curiosity.

"I can almost remember that I just read faster."

Qin Yi nodded and said slightly modestly.

"Can you never forget it?"

When Wen Xueying heard this, she seemed to think of something, and she was a little excited, and asked with adoring eyes.

"Reluctantly."

Qin Yi touched the back of his head a little embarrassed and said.

"Wow~ There really is such a god and man, I have only heard of someone who can never forget it, but I have never seen it, I didn't expect to really meet one today, you are so good."

Seeing Qin Yi nodding, Wen Xueying's eyes suddenly widened, and she looked at Wang Ying carefully, this appearance was ordinary, slightly shy, and she could never forget it, she couldn't help but give Qin Yi a thumbs up.

"If you pass the prize, that is, you have a better memory, in fact, that's it."

was praised by a beautiful woman for giving a thumbs up, Qin Yi was also the first time he encountered it, and he immediately felt even more embarrassed, and said very modestly.

"I can't forget, this is very remarkable, it turns out that there really is such a god and man, no wonder you read books so fast, where are you reading books, it's just a flip book."

Wen Xueying was also incarnated as a fan sister at this time, and she seemed to have an urge to find Qin Yi for an autograph, and when she looked at Qin Yi, her eyes changed.

"Haha, it's about the same as flipping through a book."

Qin Yi smiled.

"My name is Wen Xueying, Finance 1701 class of the School of Economics and Management, what about you?"

Wen Xueying stretched out her right hand very generously and introduced herself.

"My name is Qin Yi, and I am in the 1801 class of Power Engineering and Engineering Thermophysics of the Institute of Science and Technology."

Qin Yi introduced himself with a smile and shook hands with the other party gently.

"Level 18, it seems that you are still my junior brother."

Wen Xueying smiled and said.

"Eh, hello senior sister~"

When Qin Yi heard this, he was slightly stunned, smiled and said.

"Let's add a friend on WeChat, and if I encounter a problem I don't understand in the future, I will ask you for advice."

Wen Xueying heard Qin Yi's words, smiled, took out her mobile phone and said.

"Learn from each other~"

The other party is so generous, Qin Yi naturally can't really refuse stupidly, and took out his mobile phone to add WeChat friends to the other party.

"I still have something to do, so I'll talk about it here first, will you come here to read in the afternoon?"

Wen Xueying added a message to the end of Qin Yi's friend note, flipping through the book, and suddenly couldn't help but smile in her heart, but it showed that she was asking Qin Yi about his plans for the afternoon.

"I come here in the afternoons and evenings to read."

"Okay then~ Then we'll see you in the afternoon."

"Well, see you in the afternoon~"

Qin Yi watched Wen Xueying leave, smiled, and continued to pick up his pile of books, returning them one by one to their original positions, while looking for the books he wanted to see during his lunch break.

After paying back the book, he borrowed a new book, Qin Yi left two books in his place, occupying this position, there are many people reading books in the morning, and more people reading books in the afternoon and evening, if you don't occupy the position, it will definitely not be used, because there is absolutely no place.

The same is true for Wen Xueying's position next to her, she has already placed a few books on it, although the position of the Huaxia University library is very tight, but even if you put a piece of paper, no one will occupy this position.
