The eighth day of the Lunar New Year of the Snake in the Chinese lunar calendar.

Xingcheng South High-speed Railway Station, platform three.

Lao Xia was looking at a pair of beautiful women ten meters away and kept sighing, which made Liu Lu next to him annoyed. He couldn't help complaining: "That's enough for you! Isn't it just a gift for someone? It's so hard to celebrate the New Year. If you can stay at home for a few days, why don’t you go on this whole trip?”

Lao Xia glanced helplessly at the woman next to him and complained: "Didn't you see that the girl hugged you?"

Liu Lu sneered, and then said: "It's as if you haven't hugged me before."

Lao Xia was startled, and then muttered subconsciously: "I have to avoid people anyway. How could I dare to do this in front of adults?"

Liu Lu's smile became even colder, and she said disdainfully: "Oh, the performance of a cowardless person still makes you feel glorious?"

Okay, Lao Xia finally figured it out. In fact, his wife didn't feel very comfortable either. She could only sigh and said: "Hey, if that guy Qiao Yu takes the initiative to hug Wen Nu, I won't say anything. But it's us. I heard that the girl took the initiative to hug someone!

It's not that Qiao Yu is not good, but he went to Yanbei University, and if he meets someone better than Keke... Hey, it would be okay if Qiao Yu is not so good, but this has already spoiled Keke's appetite. I'm afraid that in the future, when Keke reaches the age where she really deserves to fall in love, she will be compared to Qiao Yu... ugh

Liu Lu said in a muffled voice: "Okay, I really like to worry about it! At most, our family won't marry in the future, and it's not like we can't afford it? Besides, Qiao Yu is not that kind of person.

"How can a fifteen-year-old child have any certainty?"

"You're still talking nonsense, right?"

"Ahem..."

At this time, Qiao Yu was looking at Qiao Xi next to him, helpless.

After all, Lao Xia and Liu Lu were employees of Tie Boss. Although they did not have the power to let Qiao Yu take the high-speed train to the capital for free, they still had the ability to bring a child to the station first with the work permit and give him a ride.

Who would have thought that this girl Xia Keke would hold Qiao Yu in her arms and cry as soon as she arrived at the platform.

Without saying a word, he touched the clothes on Qiao Yu's shoulders with both hands and buried his whole head in Qiao Yu's chest, sobbing constantly. Qiao Yu could feel some warmth on his chest through the clothes.

It would have been fine if the two of them were alone together, but Lao Xia and Liu Lu were standing next to them, making it so noisy that Qiao Yu didn't know where to put his hands.

He couldn't just raise his hands, right?

In the end, I could only carefully put it on the girl's back and pat it gently...

I expected Qiao Xi to persuade Xia Keke to leave, but Qiao Xi just irresponsibly looked away and looked into the distance to wait for the high-speed train to come.

Well, there is no hope.

Qiao Yu glanced at Lao Xia and his wife in the distance from the corner of his eyes. After realizing that they had no intention to step forward for the time being, he lowered his head and mumbled softly: "It's almost done. I promise that I will survive this time when I conquer Yanbei." Can you come back soon?"

The small white hands holding Qiao Yu's arm and clothes loosened their grip, and then gave Qiao Yu a slap. Hey, it was very light, and it didn't hurt at all.

"Isn't this enough? Well, I will make sure that the general will not be distracted by those foreign women from Yanbei. I promise that those who are single will go and those who are single will come back. That will be all right, right?"

"Bah, how rare!" Xia Keke finally raised her delicate little face and glared at Qiao Yu. Her eye circles were red and reflected light, but she still pressed against him without hesitation. "Ahem, that The daughter needs to avoid her father!" Qiao Yu almost whispered this time, fearing that his voice would drift into Lao Xia's ears with the wind.

After all, Lao Xia was beaten by Lao Xia because of these words, and he didn't even feel wronged.

As the saying goes, don't do to others what you don't want others to do to you. If any boy dares to say such things to his daughter in the future, Qiao Yu thinks that the boy can take care of himself for the rest of his life. That means he is not a good father. Man. , most of them are like this, there are some things that you can do, but others can never do.

"Qiao Yu, stop making trouble!"

"Okay, okay, no fuss, but you have to let me say goodbye to my mother, right?" "Auntie, Qiao Yu is going to leave and he still bullies me."

"Huh?" Qiao Xi looked away and glanced in front of Qiao Yu and Xia Keke. After thinking for a long time in distress, she finally said: "Qiao Yu, remember that you bullied girls, so you have to be responsible!" "Ah. ?!" Qiao Yu was stunned, and Xia Keke smiled shyly, although her eye circles were still red, like a rabbit, well, a rogue rabbit.

Qiao Yu didn't even know what Xia Keke was enjoying. He had bullied so many little girls when he was a child, and they were all responsible. He would be exhausted!

Seeing that the two young people were finally separated, Lao Xia also pulled Liu Lu over and coughed twice: "Ahem..." and then Xia Keke rolled his eyes in annoyance. However, Lao Xia was unmoved. Men all had the same idea, so it was almost okay. He went to school, not really on the battlefield. If he continued like this, Lao Xia felt that he could no longer suppress his anger.

"Qiao Yu, you must study hard when you go to Yanbei University. Well, you must not let down this rare opportunity." Lao Xia, who had not read many books, choked out such words of encouragement. "Don't worry. Well, uncle, I'm pretty good at this."

"Yeah!" Lao Xia nodded seriously, then looked at Qiao Xi.

It's time for this mother to say something, otherwise it won't be a problem for her two children to stick together all the time.

Qiao Xi looked at Qiao Yu and said seriously: "Don't cause trouble in the capital. I can't afford it. I still want you to live well." "Mom, I never cause trouble, okay! Not to mention my mentor. I am very capable of doing ordinary things!"

"Okay, Keke, come here. Passengers are starting to get off the platform. The train will be here soon." Liu Lu waved to Xia Keke. Indeed, there were already a large number of passengers carrying boxes on the platform in the distance. Come.

Xia Keke reluctantly glanced at Qiao Yu again, finally let go of her hand, and returned to her mother, but her eyes were still fixed on Qiao Yu.

"Well, you have to work hard. There are still two and a half years left. Don't even fail to pass the Yanbei University exam and have to cry again!" Qiao Yu, who finally felt relaxed, said an old-fashioned lesson. "Don't worry! I will definitely be admitted to Yanbei!" Xia Keke shouted unconvinced, which made Lao Xia feel frightened.

What kind of family? It's always Yanbei, Yanbei's... If his daughter is really admitted to Yanbei University, he has to set up a table of at least fifty, right?

Thinking of this, when he saw Qiao Yu going to Yanbei University, he didn't even ask anyone to celebrate. The intimate scene of the two little guys just now automatically skipped from Lao Xia's mind. Qiao Yu, this kid, can be escorted by his own ability I don’t know how much hardship I endured at Yanbei University. Alas, it’s all so difficult!

The train finally arrived at the station with Lao Xia, a rough man, filled with knotted melancholy.

Qiao Yu checked his ticket and got on the bus, put down his luggage under the guidance of the flight attendant, waved his hand out the window, and closed the door.

The high-speed train is not only fast, but also efficient. It only takes three minutes to stay at Xingcheng South Station, which is actually quite good. High efficiency can always dilute some of the lingering sorrow of separation. But when the train started moving, I saw Xia Keke through the window. Suddenly, water droplets started to drip from his eyes again, which made Qiao Yu feel a little emotional.

Well, after all, there is one more person he has to worry about. Alas...

It is so difficult to be an excellent man!

He waved vigorously out the window again, until the platform was out of sight, Qiao Yu took out his laptop from his bag, and leaned comfortably on the business seat, which was as comfortable as a massage chair. He suddenly felt what Yu Wei said that day. Maybe it's not just about showing off your superiority.

After sitting in the business class once, Qiao Yu really felt that the treatment in other carriages was too poor.

Not only can you ring the bell and make various requests whenever you need it, but you can also provide free meals at any time... However, old Xue Cheng will not deceive him, and he must study with the right tutor! If it were another tutor, he probably wouldn't be able to Are you so generous and directly book a business class seat for him? The more likely option is to directly send a message to confirm the time to come to school, and then let him find a way to get there on his own.

The whole journey was silent.

The business car Qiao Yu was sitting in only had six seats. Although it was full, it was quite quiet.

Maybe Qiao Yu was lucky and didn't meet the kind of big boss who kept chattering on the phone. The other five people were either holding foldable screen phones and operating on laptops like Qiao Yu. Everyone looked very busy. Qiao Yu didn't see anyone lying down on the chair to sleep. This also made Qiao Yu quite emotional. Sure enough, a ruthless person who is willing to spend money is also very ruthless to himself.

Originally, he planned to take a rest after lunch, but the people in the car were working too hard, so he stopped thinking about taking a lunch break and kept listening to the class with headphones on. The train arrived on time, and Qiao Yu followed Lao Tian's instructions and left from the east. He stood there and after looking for a long time, he didn't see anyone holding a sign with his name on it.

Just as he was about to call Lao Tian to find out what was going on, he suddenly heard a familiar voice calling him. "Qiao Yu, this way."

When I went to escape the reputation, I was stunned. The first thought in my mind was that the train had gone to the wrong place and gone to Xiaozhou...

"Hey, Teacher Xue, why did you come to the capital? Don't tell me, you used to have a very good temperament by yourself, but then you stood together with a bunch of people and your temperament was buried. I didn't even notice." Xue Song couldn't help but glare at this guy.

When they were not acquainted, Qiao Yu respected him very much. After they got acquainted with him, he dared to say anything.

"Your tutor transferred me to Yanbei University and asked me to be responsible for taking care of you. You can understand that I will be your little tutor from now on." Qiao Yu was shocked by this sentence.

Although Qiao Yu had never been in university circles, he could still imagine how difficult it would be for a university professor to transfer across provinces, let alone enter a first-class university like Yanbei University.

As a result, Director Tian didn't say a word and transferred Lao Xue to Yanbei University as his junior director? No wonder Lao Xue said that Director Tian could handle things. He was really capable of handling things.

"No, Yanbei University was not opened by our field, right? Doesn't it mean that it can be adjusted if it is adjusted?" Qiao Yu couldn't help but sighed. Lao Xue glared at Qiao Yu: "Don't talk nonsense outside, don't give it to you The instructor is causing trouble.”

Qiao Yu spat, the capital was really not an ordinary place, the bold old Xue started to become cautious when he came to the capital.

"Oh, by the way, Teacher Xue, help me drag the box. I have to call my mother quickly." After saying that, Qiao Yu handed the box in his hand to Lao Xue, took out his mobile phone and said he wanted to make a call. , but I directly clicked on WeChat to start the video. The video was connected immediately.

"Hey, Mom, I've arrived in the capital, and you'll never guess who's coming to pick me up." "Oh, who is it?"

"That's Professor Xue from Yujiang University that I told you about. He has also been transferred to Yanbei University and will be my full-time tutor in the future. Moreover, he came to pick me up today, so don't worry." Xue Song, who was walking next to him, saw Qiao Yu pointing the front camera of his phone at him, so he could only raise his hand and say hello to the phone screen: "Hello, Qiao Yu's mother."

"Professor Xue, hello, Qiao Yu would like to trouble you. This child is a bit naughty. Please pay more attention." "Don't worry, I will take good care of him."

After the adults had a simple exchange, Qiao Yu turned the camera on herself again: "Okay, Mom, Professor Xue and I are going to take the bus. I'll call you after we settle down." "Wait a minute, Coco is here too. Well, you have a word with Coco."

As he spoke, another face came into view.

It's good, at least I'm not crying anymore, but my eyes are still a little swollen. "Um, Coco-san..."

"Who is your classmate, brother Qiao Yu."

Hearing this familiar voice, Qiao Yu let go and said, "I'm telling you, I'll leave my mother to you. You can help me take care of her while I'm in the capital!" Xia Keke's eyes brightened visibly. After a while, he nodded vigorously: "Well, don't worry."

"Also, I'm waiting for you in Yanbei, so I can't stop studying. Later I'll get you some college entrance examination practice questions from the capital and send them to you. I'll go back to check during the summer vacation."

Qiao Yu originally thought that Xia Keke would refuse, but to his surprise, the girl actually nodded seriously and said, "Okay, then we have an agreement! I will finish all the questions you sent carefully and wait for you to come back to check!" "This is...the Holy Body of congenital masochism?"

"Okay, brother Qiao Yu, you have just arrived, and you still have a lot of things to do. Let's go and do some work first. I won't tell you anymore!" After saying that, the person over there even took the initiative to hang up the video.

Isn't this because Qiao Xi has brainwashed her?

"Is that your little girlfriend just now?" Xue Song asked next to her.

Qiao Yu put the phone back in his pocket and naturally changed the topic: "I have a sister at home. By the way, what is the lecture about that Director Tian asked me to attend?" This trick was very effective, and Xue Song was really too lazy to be there.

After asking about these messy things, I asked: "Do you understand the Spiro problem?"

Qiao Yu shook his head in confusion.

Xue Song smiled and said: "But Mordell guesses that you should know that Faltings' theorem was used in your paper."

Qiao Yu nodded immediately and said: "I know this. For any smooth projective algebraic curve with a genus greater than or equal to 2 defined on the rational number field Q, the set of its rational points is limited." Xue Song explained: "Spiro question you

It can be understood as a continuation and deepening of Model's conjecture, which is mainly about the precise upper bound estimation of the number of rational points on such curves.

Simply put, Model's conjecture is an existence problem, which only concerns whether the set of rational points is finite or infinite; while Spiro's problem is a specific problem about the number and estimation of these rational points. It belongs to number theory and algebraic geometry.

Intersecting research areas."

Qiao Yu nodded and probably understood the meaning.

On the one hand, it allows you to feel this kind of atmosphere. Usually you can’t ask questions while watching videos online, but face-to-face lectures are different. You can have the opportunity to ask questions directly to the scholars. Secondly, this kind of lecture is a rare opportunity, and you don’t know what it will be like next time.

Can you invite people here?
