Jiang Xuehan's biological clock is very accurate, he will wake up at six o'clock, and after waking up, he will go downstairs to the activity square of the Jinguiyuan community to exercise, and last night I saw that there is a large activity square in the Jinguiyuan community. In just ten minutes, many retired cadres and professors came to the square one after another, some of them were practicing Tai Chi, some were exercising with fitness equipment, and some were dancing.

Jiang Xuehan ran around the square a few times and then stood under a camphor tree in the community square, running the internal force for a week, causing all the cells to jump up and be full of strength, and immediately explored his own space, where medicinal herbs grew luxuriantly, and the Dan room was full of bottles and jars, and the medicinal fragrance was rich. His own bamboo building exudes a quiet fragrance under the sunlight, and you can also hear the sound of the waves of the vast sea in the space.

There is also the undulating mountains not far from the bamboo building, the trees are lush and lush, grandpa's ashes are the highest peak that she has spent a lot of effort to bury in the space, Jiang Xuehan believes that the gentle breeze will soothe him, the towering ancient trees will accompany him, and he will always protect him, in fact, life is almost the same everywhere, Jiang Xuehan was suddenly relieved.

After beating his exercises again, Jiang Xuehan walked home slowly.

Jiang Luyao said that he wanted to tutor, and went to school with Ning Yuan early in the morning. Comrade Jiang Aiguo had to attend classes, and there were occasional classes on Saturdays at the university. Jiang Aiguo's Faculty of Science is full of talents, and students who are good at mathematics generally do well in other subjects, after all, mathematics is the foundation of all other disciplines. But for most people, math is like a mountain.

Jiang Xuehan decided to go to the library with Lu Yinghua, after all, she had no other place to go, looking at Lu Yinghua's performance, it seems that Jiang Xuehan often went to the library with Lu Yinghua to read books.

In Jiang Xuehan's view, the library is the most important component of a university, and the level of the school can be roughly understood through the library of a university.

Many foreign libraries have been designed with ingenuity, and the famous Harvard Library at four o'clock in the morning in the previous life is called a model, but the library of Huaguo University is not bad, and it has its own merits.

The library of Shanghai Jiaotong University can become its landmark building. It covers a large area, has a large collection of books, and the paper books and electronic information resources are very rich and updated quickly.

The library has five floors, each with four pavilions. Several librarians take turns in each cabinet. There is also a special study room for students to study on their own, and the study room is not managed by a teacher, and students supervise each other.

Lu Yinghua wanted to go to work, so he asked Jiang Xuehan to go shopping by himself. Because Jiang Xuehan didn't have a student ID and couldn't borrow books, but Lu Yinghua could, so Lu Yinghua told Jiang Xuehan to sort out the books to be borrowed if she needed to register them.

After watching Lu Yinghua go upstairs, Jiang Xuehan studied the library distribution map in the hall and decided to go to Zaizhong Pavilion, which belongs to science and technology on the second floor, and then to Wenyuan Pavilion, which belongs to social science on the third floor.

Gently pushing open the wooden door, a burst of ink smell came to his nose, and Jiang Xuehan tiptoed in.

There are ten apricot-colored bookshelves neatly arranged in the pavilion, and each bookshelf has a corresponding call number, and people who often borrow books should know that the call number is an important basis for book lending and collection inventory.

The cabinet is almost full of people, and the figure of struggling to write books is everywhere, and every time on the eve of the exam, whether it is good or bad, students rush to the library to take a seat to review, as if this will not fail the course, this situation is a common scene in almost every university.

It's rare to see someone as leisurely as Jiang Xuehan.

Jiang Xuehan's petite and delicate appearance is not a college student at first glance, it is easy to think of being a teacher's child, everyone sees her shuttling between the bookshelves and browsing only when she is playing, who knows that she is thinking about the content of the book in her hand.

"History of Missile Development".

Jiang Xuehan is very interested in all kinds of military weapons and equipment, has done a lot of research, and has also improved a lot of weapons.

From 1997 to the 22nd century, China's weapons research has continued to develop and many brilliant achievements have been made. Jiang Xuehan briefly flipped through the book and found that the concept of a missile that he focused on was still in the theoretical stage and had not made a breakthrough in practice, but this idea had already been realized by the end of the 21 st century in the future.

Jiang Xuehan took the book, looked around the seat, found an empty seat, hung the backpack he carried on the back of the chair, took out a pen and paper, and began to calculate.

Slowly pushed from the initial concept, and soon filled three sheets of paper, and the meaning of continuing to write. Extrapolating to the key point, Jiang Xuehan is ready to calculate in two different ways, based on her previous research, the second way, that is, the way she has researched, will be better. Write and calculate, Jiang Xuehan got the final result. And then check it out, and sure enough, that's right. Jiang Xuehan couldn't help but smile with satisfaction.

I put down my pen, did a few shoulder extension exercises, looked at my watch, and found myself sitting here for more than two hours before I knew it, and the library opened at eight o'clock, and now it's past ten o'clock.

Pack up pens and paper, put backpacks on your back, and put books back on the shelves to reduce the workload of the administrator, although you can put the books on the table and let the administrator clean them up.

Leaving Zaizhong Pavilion, Jiang Xuehan went upstairs to Wenyuan Pavilion on the third floor. In Wenyuan Pavilion, Jiang Xuehan unexpectedly met Lu Yinghua.

"It turns out that Lu Yinghua is the administrator of Wenyuan Pavilion. Jiang Xuehan said darkly.

Lu Yinghua was very happy to see Jiang Xuehan coming, her eyes smiled and beckoned to Jiang Xuehan to come over. Jiang Xuehan walked straight and sat next to Lu Yinghua. Lu Yinghua took out all kinds of snacks from the drawer for Jiang Xuehan to eat, Jiang Xuehan picked up a candied fruit and put it in his mouth, it was sweet, and his mouth was suddenly full of fruity fragrance. Or the current food safety and hygiene, Jiang Xuehan said secretly, the taste is authentic, Jiang Xuehan in his previous life rarely ate outside food since he had space.

Lu Yinghua leaned into Jiang Xuehan's ear and whispered, "Hanhan, you read a book for a while, and after work in a while, the two of us will go to dinner with our father." ”

"Okay. Jiang Xuehan nodded and whispered, put the backpack next to Lu Yinghua's bag, and got up to find a book to read.

Jiang Xuehan looked at the "Atlas of Geography and History of China" with relish, and put a candied fruit or almond into her mouth from time to time.

Lu Yinghua went to inspect from time to time, sorted out the books left by the students on the desk, put them back on the shelves, and then cleared the empty spaces for other students to use.

The final exams of the university are also approaching, and everyone's pressure is great, which invisibly increases the workload of the librarian, no wonder Lu Yinghua couldn't hide the tiredness on his face when he went home yesterday.

Jiang Xue thought about it, found the Living God Pill and Mingshen Dew that had been refined before from the space, and prepared to secretly eat it for Lu Yinghua, Jiang Aiguo and Jiang Luyao at night. These pills and potions are all natural herbs, which are refined and discharged to make the final product, which has no side effects and excellent results.

After Jiang Xuehan prepared the Living God Pill and Mingshen Lu, he shifted his mind to the book, and Jiang Xuehan did not close the book until the library's end bell rang.

At 11:40 a.m., the library closes work and goes to work at 2 p.m. Jiang Xuehan put the backpack on her back and handed her Lu Yinghua's bag. The two rushed to join the patriotic comrades of Tongjiang.

Walking on campus, Jiang Xuehan saw students coming and going, alone or in groups. The students on the university campus come and go in a hurry, changing and changing, and the school is still there, just a little wind and frost, but it is like the wind in the past, but there are always some stories that people will never forget. This is Shanghai Jiaotong University in June, where the summer of June is never tireless.

After lunch, Jiang Xuehan proposed to go to Jiang Aiguo's class to listen to the lectures, in fact, she wanted to know about the teaching staff and teaching level of Huaguo in 1997, and also wanted to know what the current situation of college students was at this time.

Lu Yinghua went back to the library to continue working, Jiang Aiguo took Jiang Xuehan to the office, it was still early before the class time, Jiang Aiguo asked Jiang Xuehan to take a nap first.

The office was divided into several small cubicles of equal size, a few potted plants were placed on the balcony, and Jiang Aiguo also had a pot of cactus balls on his desk, and there was no teacher. There are a few small beds in the small room next to the office, and usually the teacher will bring his own towel blanket to spread out if he wants to rest. Jiang Aiguo took out his towel blanket from the cabinet and gave it to Jiang Xuehan, and asked her to spread it on the small bed to take a nap.

"Dad, aren't you sleeping?"

"You sleep, I'll be in the office to prepare for class. ”

"Hmm. Jiang Xuehan actually doesn't need to rest, but he still gives Jiang Aiguo a face.

When Jiang Xuehan woke up and went to the office to see Jiang Aiguo sitting on a chair and napping, little by little, he suddenly felt very moved, and at that moment Jiang Xuehan thought of his grandfather.

I heard that when you only have a glass of water, it is the brother who gives you half a glass of water when you are thirsty, the parent who gives you a glass of water, and the enemy who does not give you. More often than not, we can't ask for more, maybe what you have is all they have, and what they give them the best is what they have.

The teaching building of Shanghai Jiaotong University is divided into different areas, usually students from different faculties will only take classes in the teaching building in a certain area, so that it is convenient for students to transfer classrooms, the teaching building of the School of Science is in the Wise Building in the South District, when Jiang Aiguo and Jiang Xuehan enter the classroom, there are already some students in the classroom who are ready to go to class, Jiang Xuehan consciously walked to the back row of the classroom, although this is a stepped classroom There are many seats, but she is not a college student after all, and it is not good to sit in the front row.

The Faculty of Science will only open small classes unless it is for mathematics majors, and usually non-mathematics majors are two or three classes together, but today Jiang Aiguo teaches non-mathematics majors, and the course is "Linear Programming".

During the class, Jiang Aiguo wrote a question on the blackboard and said: "If anyone can solve this question, I will give a full score in the final exam." ”

That's okay, as soon as Jiang Aiguo's voice fell, the students in the classroom were excited, and they got a full score directly! So the students all looked at the blackboard intently, and even the sleeping students were awakened, and some students had already staged the calculation on the scratch paper, but this question was not so simple, Jiang Xuehan waited for twenty minutes and still no student could walk up and do it, but in Jiang Xuehan's heart, this question was not difficult.

Jiang Xuehan shook his head regretfully, it seems that ...... , but he didn't think that he shook his head and was looked at by Jiang Aiguo on the podium.

"Can anyone do that? I can also grant him a reasonable request. Jiang Aiguo spoke again, his eyes aimed at Jiang Xuehan from time to time, as if he was trying to say it.

Jiang Xuehan thought that this Jiang Aiguo was really enough, he was only in junior high school, and he wanted her to do college questions, but he still stood up and walked straight to the podium, picked up the chalk and brushed it up, and after writing the last zero, Jiang Xuehan smiled at Jiang Aiguo.

Jiang Aiguo really wanted to hug Jiang Xuehan up and kiss her a few times, his daughter was really amazing! It's just that Jiang Aiguo was not too embarrassed in class now, so he just patted Jiang Xuehan's head and asked her to return to her seat.

……

After returning home, Jiang Aiguo kept smiling, not like Jiang Xuehan at the first glance of Jiang Aiguo, Jiang Aiguo was very serious at that time, Jiang Xuehan couldn't help but ask Jiang Aiguo why he had a cold face last night, Jiang Aiguo scratched his head in embarrassment and said: "When I went out to eat last night, I accidentally ate an anise, it was very bitter." ”

After hearing this, Jiang Xuehan turned around and walked to the bedroom to close the door, thinking that yesterday he made a mistake in judgment, although Jiang Aiguo was proud but not serious, in fact, his personality was still a little **.
