Just turned over a new leaf and became a wise and intelligent student

Chapter 400: Cooling off by the pool, special visitor

After Xu Qingshan hung up the phone, he and Jiang Huanxi looked at each other.

Jiang Huanxi sat up and folded the quilt while asking.

"As I recall, you've already opened a separate family tree before?"

Jiang Huanxi later heard from Lin Yuehua about the incident in which Xu Qingshan went back to his hometown village and made a scene with his relatives. Jiang Huanxi felt that Xu Qingshan was right to do so.

Of course, Jiang Huanxi was also aware of the fact that he was singled out for the family tree.

“Yes, but this time it’s a little different.”

Xu Qingshan had a strange expression on his face.

“Do we need to open another page?”

Jiang Huanxi was puzzled. This generation of young people really didn't know much about these traditional things.

Xu Qingshan shook his head.

"It's the Xu family's genealogy that needs to be revised. In my family tree, I am the original family member."

Xu Qingshan didn't understand how this would be done, but Xu Xuejun told him that the original genealogy would be retained and maintained at a normal pace, but Xu Qingshan's genealogy would also be maintained synchronously. However, unlike the regional ones, Xu Qingshan's separate genealogy was the Xu Family of the Min Yue Huishan Hall.

This was the consensus reached by the elders after contacting other Xu clan members in Minyue.

The Xu family in various parts of Minyue would add Xu Qingshan to their family tree, and Xu Qingshan had his own family tree, with him on the first page.

The previous genealogy ended with Xu Xuejun's generation and was compiled into a book.

This is Xu Qingshan’s second book.

In this regard, Xu Qingshan's evaluation is "6".

He understood the Riemann hypothesis, the twin prime conjecture, and neural networks, but he didn't know much about the customs of the Min Yue clan and had no idea whether this operation was legal or authentic.

I can only say that it sounds a bit over the top.

"Are we going back to Longjiang?"

Jiang Huanxi got up from the bed reluctantly. The air conditioner was on in the room in summer, so it was hot once she walked out of the door. She forgot to draw the curtains before going to bed last night, so she was woken up by the sunlight.

"Let's talk about it later. Given the current situation, we may not be able to go back."

Xu Qingshan also stood up and stretched his body.

He glanced at the calendar on the desk and realized that it was already the end of August. The normal start time for Beijing University is in late August and early September.

"By the way, when does school start?"

"We? Why are you still going to school when you've already graduated? I'm going to start school next week, and I have to report to school then. If we don't go back to Longjiang, we'll go live in Yandongyuan?"

Jiang Huanxi suddenly thought of something and paused.

"By the way, Tong Tong and her classmates should start school early. Should we accompany her to report? If we have a house in Yandong Garden, Tong Tong won't have to live in the dormitory, right?"

"Ask her for her own opinion."

Xu Qingshan thought about it and decided not to make a decision for Tong Tong.

After leaving the room, Xu Qingshan saw Tong Tong sitting in the yard with his grandmother to enjoy the cool air. The older generation was somewhat averse to air conditioning. The old lady would rather sit under the shade of the trees in the yard and watch the koi in the pond swimming slowly than go back to the living room to watch TV with the air conditioner on.

Fortunately, Lin Chenhua had someone bring in several lounge chairs, so the remaining tree could really provide some cover.

When Xu Qingshan came out of the room, the young girl and the old lady sitting under the tree noticed him.

"The sun is about to burn your butt, are you finally willing to get up?"

When the old lady saw her grandson, she opened her mouth and spoke.

"hey-hey."

Xu Qingshan touched the back of his head and came over to sit down.

"Brother went out to win glory for the country this time, so it's normal for him to adjust to the jet lag."

Tong Tong sat next to the old lady, hugged her arm, and whispered to defend Xu Qingshan.

The old lady glanced at Tong Tong and tapped her nose.

"You are just a soft-hearted person. You can't keep silent to your family when school starts in a few days. If someone bullies you, you have to tell them."

"OK."

Xu Qingshan watched the old and the young chatting in front of him, and it was not easy for him to interrupt. He was about to take out his cell phone to check the messages, but the old lady stared at him.

"In a few days, you will accompany Xiaotong to report to school. If Xiaoxi is free, come along too. With you two brothers and sisters in school, she will have someone to rely on. Others won't dare to bully her. Otherwise, if they hear that we are from a small place, they will..."

The old lady seemed to remember some things that happened in the past and explained them seriously.

"Grandma, it's already 2010, and this is Kyoto University."

Xu Qingshan smiled and comforted.

Unexpectedly, the old lady glared angrily.

"It's the same in every year. There are always things happening everywhere. If something happens to us, it's 100%. We should be prepared for the worst."

The old lady kept nagging Xu Qingshan and told him not to be careless.

Xu Qingshan smiled helplessly and agreed.

Tong Tong watched Xu Qingshan being scolded by his grandmother, and was so engrossed that he started laughing as he watched.

She didn't have much time to meet Xu Qingshan on weekdays, and when she was busy, her smile was not so easy to show in front of others. When she smiled at this time, Xu Qingshan happened to glance at her and was stunned.

original.

Tong Tong has grown into such a beautiful girl.

Now, if Tong Tong and Jiang Huanxi stand together, Tong Tong actually looks more mature than Jiang Huanxi.

Girls change a lot when they grow up.

"What is grandma talking about? What should we eat for lunch?"

Jiang Huanxi finished washing up and came out from the corridor. Compared with Tong Tong, who looked more fierce, Jiang Huanxi was obviously more energetic and looked like a little sun.

"Xiaoxi, why did you get up so late today? Don't stay up too long reading at night."

When the old lady saw Jiang Huanxi, her face, which had been stern and scolding Xu Qingshan, suddenly blossomed like spring.

Xu Qingshan was stunned again. When did his old lady become so good at changing her face?

"I got up and packed some clothes in the house. Some autumn clothes."

Jiang Huanxi lied without blushing or beating her heart.

She had her own room. According to the old lady's idea, the three children should live in their own rooms.

Even though Xu Qingshan and Jiang Huanxi's affairs are almost settled now, if she really sees something, she will scold them.

So last night after the old lady went to bed, Jiang Huanxi quietly slipped into Xu Qingshan's room.

Tong Tong smiled again and glanced at Jiang Huanxi with a smile in her eyes. Jiang Huanxi could see the meaning in her eyes. Tong Tong's room was next to hers. She probably didn't hide the movement when she opened the door to Xu Qingshan's room last night from her.

Jiang Huanxi's little face was slightly red. Fortunately, the summer sun was very strong and there were some fine beads of sweat on her forehead, but it didn't look unusual or the old lady would have been able to see some clues.

Jiang Huanxi also sat down, and the four of them, young and old, chatted while enjoying the cool air by the pool.

Looking at his family members laughing and chatting around him, Xu Qingshan felt extremely relieved.

The feeling of being dazed and confused that he had originally felt due to his world-shocking achievement gradually came to his senses because of this scene, and his mood returned to its normal track from the state of floating in the clouds.

19 is old.

Even though he had lived two lives as a human being, it was difficult for him to suppress his impatience at this time to achieve such an achievement.

This restlessness seems understandable.

But for Xu Qingshan himself, this kind of impetuousness would largely prevent him from calming down and continuing his subsequent research.

Scientific research, especially cutting-edge scientific research, requires an open-minded and tenacious mind, and such a state of mind requires tranquility. Beijing University gave Xu Qingshan a few days off, and Tian Gang privately asked Xu Qingshan not to accept media interviews in the near future, all in order to stabilize Xu Qingshan's mentality.

Now it seems that what they were worried about has been achieved in this small courtyard.

At noon, Xu Qingshan personally took the lead in cooking and made curry rice for his family. It was not that he did not know how to cook anything else, but the old lady saw it in some TV series and said she wanted to eat Japanese curry pork chop rice. The family had the ingredients and the method of making it was not difficult. Xu Qingshan mastered it in no time.

Moreover, Lin Chenhua hurried back at noon, just in time for lunch. He came to Xu Qingshan to check on the recent business situation of the Longjiang base, had a meal of curry pork chop rice, and then hurried back to the base.

Everything is going smooth.

Xu Qingshan also began to reorganize the proof process of the Riemann hypothesis that he had completed at the International Congress of Mathematicians. This was a huge project, and he had to plan the argumentation method and division of labor. Not only did his own laboratory and research team need help, he also needed to choose suitable partners at home and abroad to overcome these argumentation difficulties together.

He needed to complete the proof of the Riemann hypothesis within a year and compile it into a paper for publication, so that he could truly hold the throne of mathematics.

Rested at home for two days.

Xu Qingshan also followed the old lady's example and stopped turning on the air conditioner. He moved a table under the shade of another tree in the yard and sorted out the materials leisurely and elegantly.

The four of them all have their own things to do, and they won't disturb each other. They can see people around them as long as they look up, which makes them feel safe and comfortable. Both their learning efficiency and work efficiency are surprisingly high.

only.

This quiet and peaceful situation did not last long.

This paradise in the city located on Nanchizi Street at the foot of the Imperial City finally welcomed a rare guest.

In fact, not many people know that Xu Qingshan’s home in Beijing is here. After all, his grandmother lives here, and she needs quiet to recover. So only senior managers like Qiu Jing and Wang Chuan who work with Xu Qingshan know that their boss lives here, or old friends like Lei Jun and Wang Chuan who have high enough rank and deep cooperative relationship know.

Even people from Jingcheng University and Huaqing University were not quite sure where Xu Qingshan would live if he did not live in Yandongyuan.

But today, the door of the courtyard was knocked.

Xu Qingshan was a little surprised.

If it was Qiu Jing, Wang Chuan, or Lei Jun and the others who were coming here, they would greet me in advance and ask if I was there.

After all, I usually travel around and I may not stay here.

Xu Qingshan looked at the surveillance footage, but found that he didn't recognize the people who came. There were only three of them. They looked quite serious, but one of them seemed to be holding a camera in his hand, which made Xu Qingshan frown.

"What kind of media is this? How can they even come to my house?"

Xu Qingshan felt that he was not suitable to show up. If he showed up, wouldn't it confirm the fact that he lived here? So Xu Qingshan simply called the confinement nanny who lived in the front yard and asked her to persuade the people to leave.

After hanging up the phone, Xu Qingshan continued to organize the information.

But unexpectedly, my aunt came back to the yard.

"Sir, the three people outside the door said they came here according to Director Deng's arrangement. They are producers from CCTV."

"Director Deng? Producer? Not a reporter?"

Xu Qingshan thought about it and put down the paper and pen.

I got up and followed my aunt to the front yard.

As he walked, he had already figured out who the Deng Bu they were talking about was.

He was the head of the Ministry of Science and Technology who was sitting in the middle when I went to the Great Hall to receive the award. His daughter seemed to have heard Principal Zhou say a while ago that this time at the meeting, this person was promoted to the rank of deputy director.

What has Minister Deng arranged for you to come here?

Xu Qingshan felt a little puzzled. There didn't seem to be any notification from the school. He hadn't contacted his superiors since he received the award. What was the arrangement this time?
Fortunately, he had just returned from abroad and had met with the top leaders, so he felt confident for a while.

He asked the aunt to invite the person into the front hall and waited patiently.

I saw the aunt leading three people in who were dressed very differently.

The guy walking in front was wearing an orange-red work vest and khaki harem pants, a slanted-brim hat made from an old film box, an indigo tie-dyed scarf bought in the Sahara, and metal badges of filming locations around the world on his vest. The guy behind him, the one Xu Qingshan saw holding a camera on the surveillance camera, was wearing distressed denim overalls with a black turtleneck and a leather tool belt around his waist.

The last one is sneaking around, followed by a little girl. The first two can be said to be unique, but the last one is performance art.

He was wearing a transparent raincoat over a silver-gray reflective fabric jumpsuit, carrying a backpack for sound wave monitoring equipment, with five pickup wires of different frequency bands wrapped around his wrists, and headphones on his head, the outer shell of the headphones being covered with Dunhuang caisson pattern stickers.

If this wasn't their own home, Xu Qingshan would have really thought they had just returned from the desert.

"Please take a seat, I don't know."

Xu Qingshan kept smiling and politely asked the confinement nanny to bring them a few bottles of water. The three of them looked so tired that it didn't seem convenient to invite them to the inner hall.

"Hello, God Xu. I'm Lao Ai, the director of your personal documentary in the Ministry of Science and Technology this time."

The brother in the orange vest grinned and introduced himself first.

"This is Okawa, the photographer."

"I'm Xiaoman! Sound engineer! God Xu, I'm your fan! Can you sign an autograph for me later?"

"I'm working! Stop making trouble!"

The little girl in the raincoat suddenly popped her head out when Lao Ai was introducing her, but before Xu Qingshan could agree, Lao Ai pressed her head back to the side.

Old Ai had a bright smile on his face.

"God Xu, this is the case. The three of us just came back from Dunhuang. As soon as we got off the plane, we received an arrangement from above. The Ministry of Science and Technology asked the station to let the three of us shoot an exclusive personal documentary for you. Actually, we came early today, and the ministry may not have informed you yet. I apologize for this for being a little presumptuous."

"It's okay, it's okay. The department wants to make a documentary about me?"

Xu Qingshan was stunned. This was his first time experiencing this!
