Xia Ge came to the San Cafeteria and met his sister Feng Xiner and Du Jia, and then went to the cafeteria to get a meal together.

"Brother, how about you going to the library to read books in the morning?" Feng Xiner asked carefully and tentatively while having dinner.

"Do I look like a panda?" Xia Ge replied.

Du Jia, who was having dinner next to her, laughed when she heard Xia Ge's answer. She was very clear about Feng Xiner's job accompanying her to draw comics in class. Perhaps Feng Xiner's writing skills were too poor, and Xia Ge in Feng Xiner's comics was always equal to the Panda people.

"Brother is more handsome than Panda." Feng Xiner on the opposite side answered embarrassedly.

Hearing his sister's answer, Xia Ge felt a little helpless. In his sister's cute thoughts, pandas were comparable to him.

"I haven't seen the key points you draw in the book. Tell me, do you always draw comics secretly during class?" Xia Ge deliberately pretended to be angry and teased his cute sister.

"No-----------------------------------------------------------------------------------------------------------------------------

Xia Ge only planned to tease his cute sister, but he didn't plan to make Xin'er cry. Seeing Xin'er lowering her head and crying, he quickly calmed down and said, "Brother, you don't blame you for not listening to the class. It's not that our Xin'er is not attentive, but that the teacher is not good at speaking. Xin'er doesn't like to listen, but she doesn't listen. These days, my brother has been tutoring you every day. You can draw comics in class, but you must agree to your brother a little."

"What did you promise?" Xin'er asked when she heard the brother opposite her say she came to tutor her every day.

"Of course, I must be more handsome than Pandas. I must be much more handsome than Pandas." Xia Ge replied with a smile.

When the three of them finished their meal, Xia Ge decided to go to the library later. Anyway, those three books can be finished in half an hour at most, so he should accompany his sister to clean the classroom first.

Xia Ge accompanied Du Jia and Feng Xiner to the cleaning classroom. Feng Xiner and Du Jia wiped the glass and desk with a rag, while Xia Ge was responsible for the physical work of getting clean water back and forth.

Seeing the two little lolitas rubbing the glass and the table with their sleeves in a very serious and energetic manner, Xia Ge, sitting on the chair, felt that it was also very warm to do light physical labor with the two cute little lolitas.

In this way, Xia Ge accompanied Feng Xiner and Du Jia to clean the classroom for more than an hour. Seeing that it was almost three o'clock in the afternoon, Xia Ge said goodbye and went to the library to continue painting the key points of his sister's books.

Qin Keqing looked carefully at the textbook Xia Ge left on the table page after pages. After Qin Keqing read more than ten pages of Xia Ge modified it, he was sure that the little boy was a mecha design genius who was much better than himself. This little boy even had a more thorough understanding of mecha design than his teacher.

A primary textbook that she looked ordinary, was actually modified so organizedly. The answers to each example question that Xia Ge corrected was simpler than the answer given by the original example question in the book. After reading a few pages, Qin Keqing discovered many clever algorithms.

Qin Keqing, who can be called a bookworm, is sure that these clever algorithms are definitely not available in other tutoring books.

Although it is only a primary mecha design textbook, Qin Keqing was inspired by Xia Ge's problem-solving ideas. After this book was revised, the basic theory of mecha design was more spatially organized. After reading a few pages, Qin Keqing felt that her understanding of the basic knowledge of mecha design was more thorough.

Qin Keqing believed that he did not have the ability to write primary textbooks now, let alone modified the primary basic theory textbooks that have been examined by countless generations of scholars so exquisitely. You should know that the more basic the matter is, the harder it is to modify. Those examples and explanations that have been considered truth by countless generations of scholars have now been modified in this textbook. From his own understanding, the revised theories are easier to understand.

She sat quietly in her seat, looking at the textbooks left by Xia Ge. Although it was already noon and she was a little hungry and gurgling, Qin Keqing did not get up. She was reluctant to waste her time and continued to concentrate on the textbooks left by Xia Ge on the desk.

The new solution to each example in the book made Qin Keqing sigh. Following Xiao Zhengtai’s idea of ​​doing the questions, she found that the concise solution method she always thought could be more concise and organized.

Qin Keqing did not get up all afternoon, and sat in her seat and looked at Xia Ge's book left on the desk. When the library's time-posting music sounded again, indicating that lunch time was over. Qin Keqing realized that he had read the book for the whole day. At noon, he was immersed in the absorption of new knowledge. She looked up at the empty position opposite, and the small Zhengtai on the opposite side did not appear.

Qin Keqing closed the book in his hand and looked at the watch. It was already one o'clock in the afternoon. He thought that the boy opposite should be back soon, so it would be better not to let him know that he was peeking at his book. Thinking of this, Qin Keqing reluctantly put the basic textbook in his hand back to its original place.

Qin Keqing, who was sitting in the original place, was quietly waiting for the arrival of the little boy opposite. Although she pretended to be holding a book in her hand, she was full of her mind, looking forward to the appearance of the genius boy opposite.

"When Xiao Zhengtai comes, why did I tell him? My sister read your book at noon and found that your book is well marked and wanted to borrow it for a look. If that's not good, he will know that he's peeking at the review materials he wrote." Qin Keqing was thinking in her mind how to borrow books from Xiao Zhengtai after Xiao Zhengtai appears. Out of her desire for knowledge, Qin Keqing really wanted to finish reading these three basic mecha design textbooks.

In Qin Keqing's opinion, these three modified primary textbooks are definitely considered masterpieces. Although she only read one lunch time, she felt that her understanding of mecha design was a big step deeper. Many of the problems with mecha design that have always troubled her have now read the basic textbooks for less than two hours, and she actually has some ideas.

Starting from 1:00 p.m., Qin Keqing sat in her seat and waited. She wanted to continue reading the three revised books on the table opposite, but she was afraid that Xiao Zhengtai would suddenly appear and see her peeking at his book, which would affect her image in Xiao Zhengtai's mind, so she could only wait quietly.

I usually feel that time passes quickly when I read books in the library, but now I am waiting for Xiao Zhengtai to arrive, Qin Keqing feels that time passes too slowly. Time passes minute by minute, and I want to secretly read the three books on the opposite side first several times, but finally give up. Qin Keqing waited and finally waited for Xiao Zhengtai's arrival at three o'clock in the afternoon.

Xiao Zhengtai sat down at Qin Keqing's gaze, then took out his pen, lowered his head and continued to write on the book.

"－－－－－－－－－－－－－ Qin Keqing wanted to interrupt the other party and asked the boy opposite to him to lend a book, but she was embarrassed to speak. She knew that the work this boy was doing was Xiao Zhengtai who was improving the primary textbook. If he interrupted it halfway and made him lose his mind, it would be bad. Wait and borrow it after he finished it.

Therefore, Qin Keqing continued to sit opposite Xia Ge pretending to read a book, while quietly waiting for the boy opposite to stop writing.

Finally at four o'clock in the afternoon, the boy opposite stopped his pen, and Qin Keqing also plucked up the courage to borrow a book from Xiao Zhengtai opposite him.

－－－－

After an hour of hard work, Xia Ge finally read all three of his sister's teaching materials and revised them. After revising them, Xia Ge put his pen in his pocket, then began to pack up the books on the desk, prepare to return the books, and leave the library.

When Xia Ge was packing the books on the table, he suddenly heard the beauty opposite him speak to him; "Little brother, can you borrow the books in your hand to see?"

Xia Ge looked up and looked at the beauty opposite whom he didn't know. Xia Ge, who had changed his book for a day, was already very tired, and had to stay up late to make up for his sister at night. Now Xia Ge doesn't have the mood or energy to go to the beauty opposite whom he doesn't know, and Xia Ge has no good feelings for the beauty opposite. When he was sitting here in the morning, the girl on the opposite side should not disturb her fingers, so she won't let herself disturb her.

Now I don’t know why I have to borrow my own books. Did you peek at the record in the book at noon, or look at mecha dresses, come to the library to read books designed by mechas, curious, and want to see what I wrote in the book after a day of busyness? No matter what the reason is, he doesn’t want to lend the fruits of his labor to others to watch unconditionally. Xia Ge is very low-key. He knows the value of these three revised books. If it is revealed, it will definitely disrupt his ordinary campus life. Thinking of Xia Ge’s cute smile, he pointed to the small pink sign on the desk. Then he picked up his book, left the reading room, and left Qin Keqing’s back gradually disappearing.

－－－

Seeing the reaction of Xiao Zhengtai opposite, Qin Keqing was stunned for a few seconds, fingering the sign, isn’t this a common statement for confessing his love? Ah, I was rejected by borrowing a book by myself. The stingy Xiao Zhengtai, Qin Keqing wanted to get up and chase him and continue to find a way to borrow it, but when he gave up, my sister also has self-esteem. Since I don’t borrow it, I won’t read it.

Until the night, when Qin Keqing packed up his things and left, he still regretted why he didn't chase him out a few hours ago and continued to borrow money. At least he asked Xiao Zhengtai's name. It would be easy to contact him. She was looking forward to the unknown Xiao Zhengtai continuing to appear in the empty space opposite her next Sunday, so that she could find an opportunity to explain next Sunday, or continue to peek at the other party's book at noon next Sunday, but Qin Keqing didn't know that Xia Ge finished painting Feng Xiner's textbook for one semester today, and Xiao Zhengtai came to the library again, and it is estimated that Feng Xiner's new textbook will be postponed next semester.
Chapter completed!
