Chapter 335 Song Yao's trump card
The cabin is slightly quieter.
Xu Qingzhou took off his hat, which allowed the people around him to see his appearance clearly.
Peng Jingqiu stared at Xu Qingzhou with wide eyes. His hair was messy and he didn't meet her expectations of a delicate boy at all, but he was indeed handsome and seemed somewhat familiar.
Liu Dongxuan had a similar expression. She felt that the man looked familiar, but she couldn't remember who he was for a moment.
Xu Qingzhou nodded to the two people beside him. Now he was not concerned about his messy hair, but looked at the formula on the manuscript.
It was a bit like the problem he once explained to a junior in the Q&A room about using complex analysis to prove the prime number theorem.
Both involve the need to extend ζ(s) to a meromorphic function on the right half plane.
After thinking for a while, Xu Qingzhou had an idea. He used the open cover principle to establish a series of ordered points on γ for a finite open cover. Then he used Euler's summation formula to assume that f is differentiable on [m, n].
Here, Xu Qingzhou has already started writing, because s=1 is the extreme point, and in a sufficiently small area, there is
【|ζ(s)|=|h(s)1】
Analyzing in the neighborhood, we can get: [ψ(x)≥∑p≤xlog(p)≥∑xα≤p≤xlog(p)≥(π(x)π(xα))log(xα)]
Lines of complex formulas appeared on the blank manuscript paper.
Peng Jingqiu stared at Xu Qingzhou for a long time, as if she had thought of something. Her eyes widened, and she excitedly grabbed Liu Dongxuan's hand and said, "Xu Qingzhou, Sister Xuanxuan, he is Xu Qingzhou!"
Liu Dongxuan paused, her eyes full of surprise, and found that this boy seemed to be Xu Qingzhou!
Xu Qingzhou was originally immersed in his calculations, but was pulled out of his thoughts by the excited voice. He looked at Peng Jingqiu with confusion, who had an excited expression.
"Are you Xu Qingzhou?" Peng Jingqiu's round face was full of excitement.
"Yeah." Xu Qingzhou nodded.
"Sister Xuanxuan, it's really Xu Qingzhou!"
Peng Jingqiu excitedly held Liu Dongxuan's hand and looked at Xu Qingzhou, "I grew up listening to your stories."
Xu Qingzhou: “.”
Why did you grow up listening to my stories?
He reminded: "I'm only 19 now."
Peng Jingqiu finally realized her grammatical error and blushed. She quickly corrected herself, "I was wrong, I was wrong. I listened to your stories to get through my difficult senior year of high school!"
"As long as it can help you." Xu Qingzhou smiled gently.
Liu Dongxuan was shaken by Peng Jingqiu and came back to her senses at this time. When she met Xu Qingzhou's gaze, she was hit in the heart.
Oh, it turns out he is Xu Qingzhou.
She secretly looked at the boy next to her. Well, he was much more handsome than the photos she saw on Weibo.
His hair was a little messy, but this undoubtedly made his lazy temperament more attractive.
Peng Jingqiu was still excited and said, "Hey, Mr. Xu, can we take a photo together?"
"Row."
Xu Qingzhou didn't refuse.
Peng Jingqiu raised his cell phone and took a few photos of Liu Dongxuan.
Next door, Huang Haoyu's mouth twitched, and he just wanted to say: "Fuck, it turns out that what you guys are playing is real?"
Looking at the three people taking photos together, I felt emotional again. If it was Xu Qingzhou, everything would make sense. He was not pretending, he was really awesome.
After taking the group photo, Peng Jingqiu looked at Xu Qingzhou pitifully again: "God Xu, can I reserve a WeChat friend seat?"
"Wait until you get off the plane."
"Thank you, God Xu!"
Only then did Xu Qingzhou free himself from Peng Jingqiu's enthusiasm and focus on the previous formula.
After a brief interlude, the previously lively atmosphere suddenly died down and the cabin became a little quiet.
Huang Haoyu was a little shocked. Compared with Xu Qingzhou, he seemed weak.
"That's not right. Compared to Xu Qingzhou, people in this world are weak."
Thinking of this, he felt much better.
Peng Jingqiu and Liu Dongxuan didn't say anything, for fear of disturbing Xu Qingzhou's train of thought. Peng Jingqiu glanced in Xu Qingzhou's direction from time to time, looking at the completely incomprehensible formulas on the manuscript paper with admiring eyes.
Liu Dongxuan was much more reserved. Although she felt a little excited inside, it was not as obvious as her cousin.
20 minutes passed.
Xu Qingzhou stopped writing. He had already finished answering Yang Yongze's questions and filled two full pages of manuscript paper. He looked up and glanced in the direction of Yang Yongze.
Peng Jingqiu was sitting on one side of the aisle. Seeing that Xu Qingzhou wanted to hand the manuscript to Yang Yongze, she took the initiative to say, "I'll help you."
"Thank you." Xu Qingzhou thanked.
Peng Jingqiu looked like he had taken on some important task, with a calm expression on his face. He held the manuscript paper in both hands and walked a few steps to deliver the manuscript, creating a different sense of ritual.
Xu Qingzhou took out the bottle and wanted to drink some water, then he remembered that the bottle was empty.
"Drink mine." Liu Dongxuan handed the water in front of her to Xu Qingzhou. Seeing Xu Qingzhou was stunned, she hurriedly said, "I haven't drunk it."
"Okay, thank you."
Xu Qingzhou smiled.
11 hours passed like this.
Reading materials, sleeping, eating, these three points are the same.
After sitting on the plane for more than ten hours, not to mention people in their fifties like Chu Jiangfeng and Wang Lin, even Xu Qingzhou felt a pain in his back and waist.
"Goodbye, God Xu."
At the airport gate, Peng Jingqiu waved.
"Goodbye." Xu Qingzhou nodded with a smile, and got into the car sent by the school to pick them up with Chu Jiangfeng and the others.
Peng Jingqiu sighed: "It's great that we met Xu Qingzhou!"
"Yes, I met Xu Qingzhou." Looking at the direction where the car disappeared, Liu Dongxuan murmured.
Which girl doesn’t have love in her heart?
Xu Qingzhou satisfied all her fantasies about the male protagonist in a novel.
However, she also knew that the possibility of them and Xu Qingzhou being together was slim, not because of the difference in status, but because Xu Qingzhou seemed to already have a girlfriend, and the person on the screensaver was very beautiful.
"After I got back, I posted on WeChat Moments, saying, 'Hey~ Uncle Meng is here to pick us up.'"
"Let's go."
Xu Qingzhou got off the car at the gate of the community, said goodbye to Chu Jiangfeng and the others, and walked towards the community pushing his suitcase.
It was already 12 o'clock in the morning, the dusk was thick, there were only a few vehicles on the street, and the noise of the day was replaced by silence at this time.
In the north, it is still very cold in February, especially at night.
squeak~
Xu Qingzhou pushed the door open and immediately, a sweet aroma of food wafted in. Ermao was squatting on the shoe cabinet, meowing non-stop.
"did you miss me?"
Xu Qingzhou held Er Miao in his arms and pushed the suitcase into the house with one hand.
As if she heard some noise, Song Yao half-stuck out of the kitchen with a spoon in her hand and looked at her boyfriend: "Wash your hands and get ready to eat."
Xu Qingzhou put Er Miao down and felt inexplicably moved. After coming back from a business trip, his home was warm and he could eat delicious meals. This was the life a real person should live.
"What are you doing standing there, Xu Qingzhou? Your apron is covered in grease!"
In the living room, Xu Qingzhou gave Song Yao a big hug and said, "I don't dislike you."
"I really want to beat you up." Song Yao muttered. Even though she said that, she still enjoyed the feeling of being in her boyfriend's arms.
The long black hair was scented with shampoo and the unique fragrance of School Beauty Song. The hair felt moist, and I immediately understood, "She just took a shower."
Xu Qingzhou saw it and couldn't help but nuzzle Song Xiaohua's neck.
Song Yao moved restlessly for a few times. The hot breath made her hand holding the spoon tremble slightly. "Itchy~Xu Qingzhou, are you born in the year of the dog?"
"Don't you bite me often?"
The two hugged each other for a while, and Song Yao pushed Xu Qingzhou away, "Go wash your hands quickly." "Okay." Xu Qingzhou went to the bathroom to wash his hands and helped serve the pork rib soup.
Braised pork, green peppers, stir-fried lotus root. Three dishes and one soup for two people.
I was on a business trip for a while and ate Western food every day. What I missed most was the braised pork and white rice at home.
In one meal, Xu Qingzhou ate three big bowls of rice.
After eating and drinking, Xu Qingzhou leaned back in his chair comfortably, conserving his energy, looking at the girl opposite him and exclaiming: "It's great to have a little cook at home."
"Huh, who said yesterday that they would come back and make me something delicious?"
Song Yao raised her eyebrows. Seeing Xu Qingzhou enjoying himself so much, she felt very happy and accomplished. She thought to herself, "No matter how great you are, the family still depends on me."
"It's not just rice that can be eaten." Xu Qingzhou muttered softly.
"Huh?" Song Yao looked unfriendly, suspecting that this guy was driving again.
Xu Qingzhou did not refute. He had always been in the situation of "the enemy is strong and I am weak" in this family. He just had to get used to it.
He stood up and said, "I'll go wash the dishes."
As soon as he reached out to grab the bowl, Song Yao slapped it away.
Song Yao said, "You go take a shower and I'll wash the dishes."
Xu Qingzhou instantly understood what the girl meant, but she always liked to pretend, so she pretended not to understand: "Why are you taking a shower? I just took a shower last night. Oh, I'm so tired. I'll just clean myself up and go to bed."
Song Yao narrowed her eyes. She could tell from the mischievous smile in Xu Qingzhou's eyes that this guy was pretending again.
Then don't blame her for using her trump card.
"Xu Qingzhou, are you dying?"
"."
Xu Qingzhou went to get clean clothes with a gloomy face.
In the living room, listening to the sound of running water coming from the bathroom, Song Yao curled the corners of her mouth and hummed a little tune while cleaning up the dishes.
10 minutes passed.
Xu Qingzhou walked out of the bathroom and took a quick look. School Beauty Song had already returned to the bedroom, while Er Miao was wandering around the living room with its tail swishing.
Taking a deep breath, he turned off the lights in the living room and walked towards the bedroom.
Inside, School Beauty Song had already tied up her hair and was ready for battle.
Sure enough, it was just as I had guessed.
Tonight is destined to be a sleepless night.
Xu Qingzhou looked determined and strode towards the master bedroom.
Jiejiejie~
Today he wants to make School Beauty Song understand one thing: you can eat whatever you want, but you can’t say whatever you want!
bang~
As the bedroom door closed, the last light in the living room disappeared, but Er Miao was not affected and jumped nimbly from the armrest of the sofa to the table.
puff~
It seemed like someone was knocked down, and then the sound of a Twolegged beast was heard from the bedroom.
"Song Yao, that's too much, get down!"
"No, I want to be on top."
"You're a girl, why do you always like to be on top, woo~"
Stupid two-legged beast.
The sound coming from the bedroom made Ermao's ears twitch. He meowed twice in disgust, then fell from the table to the ground, and slowly walked towards his own little nest in the corner.
The noise there is quiet.
The first night back home,
The next day, it was 9: in the morning.
Xu Qingzhou put his hands behind his head, staring at the ceiling in a daze, sleeping comfortably. The jet lag could not overcome the exhaustion that came over him, especially after returning to a familiar and warm environment.
finally home.
There has been some progress on the local smoothing effect of the half-wave operator in Euclid space. The LP estimation has been completed and things will go a little smoother next.
Maybe, I will use this as my graduation thesis.
Then there is government-sponsored study abroad.
Princeton, Cambridge, MIT
As long as he is willing, these schools will definitely extend an olive branch.
The first choice is still the United States. It has to be said that the school is the first choice. He really wants to go to Princeton because he is familiar with the place. The only difference is that he used to study physics, but this time he will focus on mathematics.
Of course, now he needs to consider the future of both of them. If possible, he would rather choose a school that is a little closer to School Belle Song.
Beside him, the school beauty Song was sleeping soundly. This girl was very majestic in the first half, but in the end he was more skilled than her and defeated her, making her lose all her weapons and scream in pain.
The girl uttered a mutter, woke up, and squeezed towards him with her eyes closed.
The two of them stuck together, and Song Yao asked, "What are you thinking about?"
"Study abroad." Xu Qingzhou did not hide it.
Song Yao still closed her eyes, "Professor Li suggested that I go to Stanford or Harvard as an exchange student next year."
"Economics is indeed a top major in both schools. Which one do you want to choose?"
"Not sure." Song Yao closed her eyes and could feel Xu Qingzhou's chest beating.
Xu Qingzhou smiled and said, "Then I don't have to worry about it. I choose MIT and you choose Harvard. Both schools are in Cambridge, Massachusetts, USA. They are close to each other and are only separated by a river called Charles River."
This is a good choice. I vaguely remember that it only takes half an hour to walk to the other school, and 15 minutes by taxi.
Song Yao opened her eyes, and just lay on top of Xu Qingzhou, poking his face, "Do you want to choose MIT?"
She was worried that Xu Qingzhou went to MIT for her.
"You followed me to the United States." Xu Qingzhou said in a deep voice.
Song Yao understood what Xu Qingzhou meant. She followed Xu Qingzhou to the United States, and Xu Qingzhou chose a school close to her. When two people are together, they have to consider each other.
"But."
Although she also wanted to be with Xu Qingzhou, if he had another school he liked more, she still hoped that Xu Qingzhou would go to that school.
Xu Qingzhou smiled and pinched her face, then continued, "No buts, MIT's mathematics department is one of the best, and it's in my backup plan."
Song Yao held Xu Qingzhou's face and kissed him hard on the mouth: "Teacher Xu, thank you."
"You woke up and kissed me again."
"Hmph, I just want to stink you." Song Yao groaned and lay back in Xu Qingzhou's arms, her soft and erect body spread out on Xu Qingzhou's chest.
Xu Qingzhou took a breath of cold air. This unintentional action of School Beauty Song was too seductive.
The clothes on both of them had been thrown away somewhere long ago, and they could clearly feel each other's every move.
Song Yao was still enjoying the warmth brought by her boyfriend, but at this moment her body suddenly stiffened and she stood up and looked at him angrily.
"you you."
There was a blush on School Beauty Song’s face. She was so tired last night, but this guy can still hold on now?
"It's a natural reaction. Who told you to move around on me? Ah~"
Xu Qingzhou would never admit that he was a pervert.
Seeing that this guy was putting the blame on her, Song Yao pinched the bad guy under her hard, and got up from the bed angrily, "Get up!"
Lying down again will lead to problems.
Today happens to be Saturday, and Jiahui and her friends are coming to play today.
Xu Qingzhou was lying on the bed. "Some people like to do things like destroying bridges after crossing them. They like it very much when they need it, but when they don't need it anymore. Woo~"
Song Yao had just put on her clothes, and after hearing these words, she was so angry that she pressed the bastard to the bed and beat him up. However, as she was beating him, she found that the clothes she had just put on were gradually slipping to the ground.
In the living room, Er Miao was laughing and lying in his nest with his head down.
Two-legged animals, are you going to let the cat sleep?
