Tech Hammer

After completing the moving work and testing in March, Ning Wei chose an auspicious day and moved back to his home community. Of course, Ningwei's method of choosing auspicious days is slightly different from others. He did not choose a day from the perpetual calendar, but used the weather forecast, atmospheric flow, and other information in March to select a recent sunny and good weather. .

Although it was not a holiday and both sisters were in class, Ningwei still felt full of happiness the moment she opened the door.

It was completely different from when he and Yu Xingwei lived together. The living room was neatly kept, the windows were bright and clean, and there wasn't even a wrinkle on the sofa cover. There were washed fruits neatly placed on the coffee table, and the TV remote control was put into a box that was probably bought specially for Double Eleven. Ning Wei had an impression of this, because on that day, he specially asked March to collect all the major TV programs. Using data from merchants, I helped Student Jiang make an optimal shopping strategy for the entire dormitory...

There is a vase on the bay window of the living room, with two green branches inserted. Yes, they are not flowers. There are a few fresh green leaves on the branches, which at least looks very comfortable. The floor was also very clean and spotless, and two pairs of women's cotton slippers were placed on the shoe rack at the door.

He really couldn't bear to step in like before, so Ning Wei opened the shoe cabinet, and sure enough, the new slippers prepared for him were already lying quietly in the cabinet.

I changed my shoes honestly, carried my suitcase and walked into my room first. The place had been tidied up. The wooden floor seemed to have been renovated. The black marks on it were no longer visible. The bed was specially made. The bedspread made Ning even more embarrassed after opening the closet. The clothes he had just stuffed in before were all neatly folded, and he could still smell the fragrance when he opened the closet door.

Seeing this scene, he was even embarrassed to put the clothes he brought back in the box directly into it. He simply threw the box next to the cabinet. Ning Wei then slipped out of the room and ran into the closed study first to take a look. It was almost the same as when he left. He probably wiped the table. The manuscript papers that were randomly placed on the table were sorted into a pile and placed on the corner of the table.

What made him feel the most was the kitchen. The entire kitchen had obviously been cleaned and looked brand new. All the kitchen utensils that were missing before had been replaced, and there was also an extra microwave. This even gave him the illusion that he It's not like he's in the capital at all, but like he's back home in Yancheng.

After he turned around, Yu Xingwei's voice came from the door: "Let me go, this is the third floor? Mr. Ning, are you there? Did I go to the wrong place?"

"Wait, don't come in yet!" After responding loudly, Ning Wei walked out of the kitchen. Yu Xingwei was standing at the door in a daze, carrying two larger boxes.

"I don't dare to come in here, right? The sofa didn't look like this before, right?"

"This is a new sofa cover, can't you see it?"

"Hey... I really didn't see it. I really thought I was in the wrong place just now. Compared with now, I feel like this place looked like a doghouse before." Yu Xingwei commented very pertinently.

"Haha, what do you mean by comparing with before? Compared with here, isn't the place where you live now called a kennel?" Ning Wei looked at Yu Xingwei with disdain and said without mercy.

"Ahem, what about that, Mr. Ning, I will clean up every two days, such as sweeping, mopping, wiping the table and so on. It seems that you haven't even touched the broom after we have been together for so long. ?”

Yu Xingwei argued, which hit Ning Wei's weakness...

Forget about brooms, Ning Wei thought about it carefully and realized that since he came to the capital and bought a house, he has completely let himself go. It has been several months since he came to the capital, and it seems that he has not even folded the quilt once. Of course, with his wealth, hiring a nanny would not be a big problem, but Ning Wei didn't like unfamiliar people doing things in his home, and he didn't seem to care much about hygiene issues before.

"Brother Yu, I'm really not talking about you, can we compare them together? The key to the problem is that I have a virtuous girlfriend, but you don't! So it is reasonable for me not to touch the broom, because someone will help me. I handle these things, but if you occasionally sweep or mop the floor, you are lazy! If you are single, you must have the consciousness of being single." Ning Wei retorted confidently.

Facts speak louder than words. Looking at the living room in front of him, Yu Xingwei found that he couldn't find a reason to refute. He just rolled his eyes and asked: "Hey, speaking of Mr. Ning, doesn't classmate Jiang have a sister? When she finishes her college entrance examination, will you introduce her to me?"

"A beast!? How can you say such a thing? Chenlu is only in high school!" Ning Wei said, glaring at Yu Xingwei.

"Didn't I tell you to wait until you graduate from high school? Haha, pretend I didn't say that. I'll get off first. Don't let the driver wait for too long." In the end, Yu Xingwei was defeated by Ning Wei's glare and held the bag in his hand. He put the box in the living room, turned around and left without even entering the door.

Well, actually, I wasn't really angry. Ning Wei simply felt that it was too early for Jiang Chenlu to consider such a thing. When Jiang Chenlu graduates from university and Yu Xingwei is still single, it is not impossible for the two of them to fall in love with each other. However, there are too many restrictions, and Ning Wei feels that it is unlikely to happen.

After moving the box containing the laptop and monitor into the study, Ning Wei looked at the time and saw that it was just half past nine. Ning Wei took out his mobile phone and logged into the school's timetable system and called up Jiang Chenshuang's timetable.

No wonder no one is here. There are four classes in total this morning. The first and second periods are microeconomics. The next three and four periods are linear algebra. The third class officially starts at ten o'clock. The class is in Room 302 of the School of Economics. . After seeing the course schedule, Ning Wei decided to surprise Jiang.

After quickly rushing into the bathroom to wash his face and change his clothes, Ning Wei left the house and went straight to the School of Economics building.

Walking out of the family area, passing by the School of Foreign Languages ​​and the Department of Chinese Language and Literature, we arrived at the east gate of the School of Economics. In fact, in terms of distance, the house Ning Wei bought is closer to the School of Economics. Opposite is Guanghua College, and we are going to the Beijing International Mathematics Research Center. , you have to walk to Jingchun Road between the School of Economics and Guanghua College, and walk several hundred meters west, passing by the podium buildings of the School of Philosophy and the Lee Shau Kee College of Humanities.

The distance was close, and the time was naturally stuck just right. When Ning Wei walked into the teaching building, it happened to be seven past ten, and there were three minutes left for class. Judging from his experience studying at Jiangsu University, when there are only three minutes left before class, most students should have already found their seats in the classroom, and this is indeed the case. When Ning Wei went up to the back door of the classroom on the third floor and took a look, the classroom was almost full.

Because linear algebra is a public course, the classroom that can accommodate more than 100 people is basically full. Only the last two rows have scattered seats. However, it only took Ningwei a minute to find it among hundreds of people. Where Jiang Chenshuang sat.

The only trouble is that Student Jiang’s seat is relatively forward, the second seat in the third row from the left, and all the seats in front of, behind, left, and right of Student Jiang are already full of people. Well, this is normal. Some people say that judging a school The status of a university can be seen by comparing the number of people attending major classes and the comparison of front row and back row positions. Obviously Yanbei University has perfectly interpreted this sentence.

But of course this cannot be difficult for Ning Wei. Now that he has decided to accompany Mr. Jiang to two classes, he no longer intends to lose face. There is a saying on the Internet that as long as you are not embarrassed, others will be embarrassed. Before the teacher came to class, Ning Wei quickly walked into the classroom with his head lowered, came to the third row, and lightly knocked on the table.

Wang Jiaying, who was sitting on her seat and flipping through a book, raised her head with a little annoyance. When she saw Ning Wei, she was stunned and unconsciously let out a soft cry: "Huh? Wow..."

The clear voice also alerted several girls next to her. Student Jiang, who was lying there doing questions, raised his head and was stunned when he saw Ning Wei. Xi Yuxuan next to Jiang and the classmates behind him were also stunned at the same time: " Dr. Ning?"

"Why are you here?" Jiang Chenshuang asked confusedly after being stunned.

"I'll accompany you to class! Shall we sit in the back? I just saw that there are two seats connected together in the back. Hurry up, it will be awkward to change seats when the teacher comes later." Ning Wei pointed to the seat in the back row.

"Ah? Oh!" Jiang Chenshuang hurriedly began to clear away the books and drafts on the table. This action also attracted more people's attention. Many people in the class began to focus on Ningwei.

After all, most of the students had already taken their seats at this time, and Ning was standing alone on the edge of the aisle in the huge classroom, which was particularly eye-catching. Not to mention that Ningwei is still a big celebrity in the school...

"Dr. Ning, how about you sit here with me and I go to the back?"

After Wang Jiaying was stunned, she stood up decisively. Ning Wei knew this girl, Jiang Chenshuang's roommate. He had met her when he went to help Jiang Chenshuang move things.

"Is this good?" Ning Wei asked.

"How about you treat us to another meal in the dormitory?" Wang Jiaying said immediately.

"I'll treat you to ten meals. I'll introduce you to a boyfriend by the way. I'll pester him every day to ensure that I won't fail the exam." Ning Wei said immediately. When he said this, he thought of Yu Xingwei, who was still single. .

"Deal!" Wang Jiaying replied quickly, then picked up the book and walked towards the back row of the classroom. Ning Wei also sat on it unceremoniously.

Everything was going just right. Ning Wei looked back. As soon as Wang Jiaying sat down, a middle-aged professor who teaches modern science walked in from the front door of the classroom. By coincidence, Ning Wei, associate professor surnamed Shi from the Department of Financial Mathematics, happened to be there. know. Well, the actual situation is that after staying in the Mathematics Research Center for a long time, Ning Wei has met most of the professors related to mathematics, so he naturally knows them.

Ning Wei turned his head to look at Jiang Chenshuang beside him, and found that this silly girl was obviously a little nervous at this time. He didn't know where to put his hands, so he thought it was funny, so he aggressively grabbed Jiang Chenshuang's hand from under the table. Hold your left hand in your hand, then sit upright and look at the podium.

From the corner of his eye, he could see that the silly girl froze for a moment, subconsciously glanced sideways at him, then raised her right hand, picked up the pen and looked at the teacher on the podium. Xi Yuxuan, who was sitting next to Classmate Jiang, saw this scene completely, then suppressed a smile and looked at the podium.

There was nothing wrong with the three of them. However, when Professor Shi was ready on the podium and coughed twice to prepare for the lecture, he found that the atmosphere in the class seemed a bit strange. Many people were looking in the same direction unconsciously, even the one in front of him. There were children in the row who glanced back from time to time, and then looked in the direction that everyone was paying attention to. At first glance, there seemed to be nothing wrong. Just as I was about to give a lecture, I suddenly felt that there was a serious boy who looked a bit familiar, and then he After taking a look, I was sure this time.

"Ahem, what are you looking at today? What's going on? I said Xiao Ning, Director Tian sent you to inspect my teaching quality, right?" Professor Shi looked at Ning Wei and asked.

"Pfft, haha..." A burst of cheerful laughter came from the classroom.

"Not at the time. Professor Shi, I suddenly felt that my foundation in line generation needed to be improved. I heard that the line generation you taught was very good, so I came here to listen." Ning Wei said seriously.

"Hey, oh, Xiao Ning's words really made me feel a bit incompetent today."

Professor Shi glanced at the girl with her head hanging next to Ning Wei, and smiled: "If you say that, you really can't stand me. Forget it, let's be sincere between us. I know you've been busy with supercomputing recently. I haven’t come back to Lele for a long time about things at the center. Director Tian has mentioned it many times on different occasions, so I know very well why you came today. So I won’t point it out to you, in case something is not taught well in class later, You are not allowed to go out and talk nonsense."

"Okay, students, please pay attention. After today's two classes, everyone will have the long-awaited midterm exam. It just so happens that Dr. Ning Wei, a well-known figure from our School of Mathematics, came to the class. If you have studied before If there is anything you don’t understand about the content, there is an excellent teacher for you to ask after class today. Professor Lu’s teaching assistants are usually active in the School of Mathematics, but they rarely have the opportunity to explain it to our students in the School of Economics, so you should take advantage of it. Don’t let him run away easily because of this once-in-a-lifetime opportunity.”

After saying that, ignoring Ning Wei's dumbfounded expression, Professor Shi opened the courseware seriously and started the class seriously: "Okay, now the class is officially started. What we are going to talk about in this class is the intersection and sum of subspaces. Direct sums, and isomorphism relations. In the previous class, everyone already understood the basic concepts of linear spaces, such as the four basic subspaces, so when..."

"I'm at a big loss. I obviously wanted to come and see you, but it turned out that there was a midterm exam. You said that class would be over later. Isn't there really a lot of people around me asking questions?" The class was being lectured, and Ning Wei was talking to me. The girl next to him asked in a low voice.

Before classmate Jiang could say anything, a piece of manuscript paper was pushed in front of classmate Jiang. Classmate Jiang took a look at it, and then silently pushed it to Ning Wei. Ning Wei took a look at it, and then felt a little dizzy.

Just as he was talking, someone asked him to help solve the problem, but when he turned his head and looked at the smiling face of the eldest sister in Jiang's dormitory, Ning Wei had no choice but to let go of Jiang's little hand and pick up the pen...

Facts have proved that it is wrong to come to show affection during class.
