I reach the pinnacle of life by learning

The final result of the last question leak was that Tianhai District added 50 places for the semi-finals.

According to the official explanation, "the number of participants in the preliminary competition is large, the scope of screening students is wide, and the incident of leaking questions has little impact", so 50 new places are completely enough.

Some are happy and some are sad, which makes many people whose scores are near the admission line see hope again.

The only small episode was that Tianhai No. 1 Middle School's first place in the preliminary competition was quietly revoked.

He didn't report the criticism, and the school has already reserved the last face for him.

Qiao Yu is still sleeping at Lu Miao's house. Unlike last time, Lu Miao's younger sister looks a lot better, and even took the initiative to go to the vegetable market to buy things: tomatoes, eggs, celery, beef, a handful of spinach, and some seasoning material.

It made Lu Miao suspect that his sister had been pierced by a soul.

In the end, after the vegetables were bought, no one in the house knew how to cook except Qiao Yu.

Qiao Yu actually wanted to say whether he should go out to eat, but two pairs of eyes, one big and one small, were staring at him eagerly, which made him unable to say this for some reason.

Lu Miao sighed, with a melancholy expression: "Brother, since we were in high school, our family hasn't had a relationship."

Lu Yunxi said with a straight face, "I...I know how to chop vegetables, and I don't want to eat takeaway."

Qiao Yu could only roll up his sleeves and said, "Okay, I'll come. Let's have tomato scrambled eggs, celery beef and spinach soup tonight."

Lu Yun claimed that he could chop vegetables, but he didn't help much.

After she finished washing the dishes and cut the beef slices in half, she was kicked out of the kitchen.

After a while, the sound of cutting vegetables came from the island in the kitchen, with its own rhythm, which was wonderful.

Lu Yun began to speak with his face in his hands, his tone full of exclamation: "Little Qiao is so kind and virtuous."

Before she uttered this word, Qiao Yu in Lu Miao's heart had always been an iron-blooded man. Although the opponent's body type did not fit the man's body, the figure of Qiao Yu stepping on mathematics and punching physics had already left in Lu Miao's heart. The imprint of an indelible hero.

But when he heard it now, he nodded in sympathy.

Heat the pot, heat the oil, add ginger and garlic, and with a "stab" sound, the beef will be put into the pot, and the aroma will come out.

Lu Miao couldn't hold back his low hand, took a picture from a distance, and posted it in the [Four Gods with a Silly] group.

Lu Miao: @All Members Qiao Yu~ is cooking for me~~~

This tone of beating is enough to make others put 10 sacks on him.

Zheng Qinghua poked out the canteen fried noodles that he was eating as a powerful counterattack.

Chu Xining turned the phone screen on and off, and finally let out a soft hum from his nasal cavity.

Lu Miao's picture was a bit blurry, and Song Tianyu could only see a blurred figure shaking the spoon, but he could tell it was Qiao Yu at a glance.

Song Tianyu was shocked: Qiao Yu can still cook? !

Qiao Yu lived in Song Tianyu's house for two weeks before, not to mention cooking, even the milk was warmed by him.

He thought that the other party was also inattentive, but he didn't expect that he looked like a familiar hand.

As soon as Qiao Yu's dishes were brought to the table, two pairs of chopsticks rushed forward swiftly.

From time to time, I could hear a few sobbing praises similar to "delicious".

The sense of accomplishment in Qiao Yu's heart slightly increased by 1.

Dinner was almost over, the two brothers and sisters fought over the last piece of meat on the plate, and finally Lu Miao successfully snatched it away on the grounds that he had an exam tomorrow.

On the second day of the math league, there will be two rounds of exams.

The first round is called a try, 150 points.The second round is called an additional test, with 4 questions and a total score of 150 points.The two rounds of questions are divided into two exams, with a 20-minute break in between.

Generally speaking, as long as you get about 210 points in the test, you can get the provincial first prize and get the independent enrollment quota of colleges and universities.And some students with particularly outstanding grades will be called to the winter camp to participate in the selection of 6 national team members together with outstanding students from other provinces.

As Qiao Yu expected, the scope of the 4 big questions in the second test was algebra, geometry, combination and number theory.

The questions given by the test teacher this time are relatively gentle. The steps of each big question are very long, and it is really impossible to do it. If you follow the relevant formulas you have learned, you may be able to score five or six points.

Qiao Yu estimated after the test, and felt that his score should not be lower than 295... As for the remaining 5 points, it's all about the details.

The atmosphere in the examination room was tense and serious, and after Qiao Yu finished the exam, he immediately felt relaxed.

Chu Xining and Qiao Yu had similar scores in the preliminaries, so they were also close to each other in the examination room.

Chu Xining walked out of the classroom, just in time to bump into Qiao Yu on the other side.

Chu Xining smiled at him: "Let's go."

The 4 contestants are in different examination rooms and make an appointment to meet at the entrance of the teaching building.

The waiting time was too long, Chu Xining couldn't help asking: "Qiao Yu, do you think you can win the special prize?"

Generally speaking, after the rematch results come out, there will only be first, second and third prizes in the province, but occasionally there will be candidates with outstanding talents, and the organizing committee will make an exception.

The organizing committee stipulates that as long as candidates who get "double full marks" can be awarded special prizes.

The so-called double full score means that both the preliminaries and the rematch are full marks at the same time.The first double perfect score winner in history is Long Fei from Huanggang Middle School.

In that year's math test paper, Long corrected the loopholes in the test paper questions and got the only perfect score.The organizing committee felt that using the provincial first prize could not distinguish a university god like Long Fei from an ordinary academic god, so they gave the first special prize.

Since then, Long Fei's deeds have been passed down from generation to generation in the competition class.However, the province is easy to get, but the grand prize is very rare.

The last time someone from Tianhai won the special prize was nine years ago.

Qiao Yu could only answer: "It's hard to say, maybe."

Not hopeless, but "maybe".

Chu Xining felt the blow again, but fortunately, he had known Qiao Yu for so long, so he gradually got used to it.

He felt that those students in No. 1 Middle School who thought he was the top student in his grade in Tianhai City should all come and see Qiao Yu.

Presumably they should have a new understanding of the term "xueba".

After the exam in the morning, Qiao Yu took the subway in the afternoon and arrived at the gate of Tianhai University.

This was the first time he saw Tianhai University with his own eyes in more than 40 years in his two lives.

As the best university in Changning Province, the gate of Tianhai University is very simple and solemn.

This university was built a hundred years ago. Because it is located in the coastal economic center, it was bombed by fascist forces many times during World War II.

The school gate, which has been through vicissitudes, has been repaired and repaired, but it still stands tall and strong.

Qiao Yu was invited by Professor Li Chujie to listen to his academic lectures for college students.

There is a bright banner hanging at the gate of Tianhai University, with a few large characters written in white letters on a red background: Welcome Professor Li Chujie from the Department of Mathematics of Yenching University to come to our school to give lectures.

Qiao Yu will be an adult next year, and she doesn't have any childishness in her body, so she blends perfectly into the group of college students.

He looked at Tianhai University, his eyes swept over the flowers and plants, Yingxin Avenue, the bronze monument of outstanding alumni, and the towering library in the distance, with rare envy in his eyes.

The system is clear, Qiao Yu has always been worried about not taking the college entrance examination in her previous life, which resulted in her not going to university.

At that time, Qiao Yu didn't dare to think about entering top domestic universities like Tianhai University, Qing University or Peking University. His dream was to study a bachelor's degree, preferably medicine, and then slowly wait for the bone marrow to treat his mother's leukemia.

Later, Qiao Yue died a week before the college entrance examination.

Qiao Yu's dream ended here.

The system couldn't help but comforted: "It's okay, you can have everything you want in this life, and it's even better than you thought before."

Domestic top2, world top2.

Abel Prize, Fields Medal, Wolf Prize, Nobel Prize.

Nothing is impossible if you think about it.

Qiao Yu smiled, quickly put away distracting thoughts, asked for directions, and followed the instructions to the lecture hall.

For this lecture, in order to make Professor Li feel at home, Tianhai University specially gathered students from the Department of Mathematics who were still on weekends, and filled the huge lecture hall to the brim.

On the log podium seven or eight meters away, Li Chujie was wearing a light gray plaid suit with a suit scarf on his chest, full of bookishness.

Qiao Yu felt inexplicably that Chu Xining might be like this when he grows up.

He randomly found a corner and sat down.

The people on the side looked at him and greeted him with a smile: "Hi, I'm Zhao Yunfei from Qiu Chengtong's class, sophomore. Why haven't I seen you before? You're not from our department, are you?"

Qiu Chengtong's class, by analogy, is probably equivalent to the "Qingyan Class" majored in the mathematics department of a university. The name is not because Mr. Qiu Chengtong personally taught in the class, but to commemorate the outstanding contributions of this Chinese mathematician in mathematics.

Qiao Yu nodded, took out the paper and pen, put them on the table in front of him, and replied, "Yes, I'm a high school student, and I'm here to listen."

Zhao Yunfei couldn't help but chuckled: "High school students? Although it's a popular science lecture, it's too early for high school students to listen to this, right?!"

Although his words were exaggerated, there was no sarcasm in his tone.

Zhao Yunfei really felt that Qiao Yu came to the lecture too early.It's like a newborn baby who is going to learn to walk before his bones grow.

However, Zhao Yunfei still appreciates the other party's learning attitude.

"It's okay, you can ask me if you don't understand!" Zhao Yunfei promised.

Qiao Yu smiled at him and said in a low voice, "Okay."

The lecture hall was brightly lit, and when Qiao Yu smiled, Zhao Yunfei felt the lights in the room flicker.

It's a pity that their row is basically full of unshaven boys, so it's a pity that no one appreciates Qiao Yu's beauty.

Li Chujie stood on the stage, adjusted the microphone, and the lecture officially started.

The topic of this lecture is "Cabi-type theorem under Ricci curvature", which is a branch of Riemannian manifold in Riemannian geometry.This is one of the fields that Li Chujie is best at, and it is also the topic of his graduate thesis.

There is no doubt about Li Chujie's academic ability, but when it comes to the level of lectures, it is a little embarrassing.

A PPT appeared on the projection screen, and a dry equation appeared.

What followed was a more dry lecture by Li Chujie: "In 1941, Professor Myers of Yale University proved a very important theorem, that is, let (M, [-]) be an n-dimensional complete Riemannian manifold and satisfy Ric... ..."

After 1 minute and 2 minutes, the students worked hard to listen to the class.

After 5 minutes, many students looked blank.

After 10 minutes, everyone became a PPT copying machine without emotion.

Zhao Yunfei's brain hurts from hearing this, and he couldn't keep up with his train of thought if he was a little careless, he just wanted to scold the school for misleading me, what the hell is wrong with popular science!

When he turned his head, he saw that Qiao Yu had written a full page with reasons and evidence, as well as his own analysis, and nodded from time to time following Li Chujie's lecture content.

Zhao Yunfei:? ? ?

Are you a fake college student?Or are the acting skills of high school students so strong now? ?

Zhao Yunfei was full of doubts and held back until the break time.

Qiao Yu lowered her head, as if she was still immersed in the ocean of knowledge. After a few minutes, she slowly recovered.

He had just put down his pen and was about to move around, when a slight cough sounded in his ears.

"Cough." Zhao Yunfei pretended to cough twice, and asked, "Student, do you understand?"

Qiao Yu thought for a moment and replied, "Basically, there is no problem."

Zhao Yunfei: "..." Damn it, is it so powerful?Why doesn't he believe it?

Zhao Yunfei tentatively asked: "Then I want to ask, what happened to the proof process of Theorem 1.4 that Professor Li said just now...?"

Qiao Yu thought for a moment, then unscrewed the cap of the pen, turned it over to a new draft paper, and the words poured out like running water.

"According to the conditions of Theorem 1.4, the following four proof methods can be divided, case 4 is..."

"Suppose there is a point S0... Integrating both sides of the inequality l1l2, we can get..."

Unknowingly, Qiao Yu's neighborhood became quiet.

A person quietly approached from the other side, listening to Qiao Yu's answer.

Not only Zhao Yunfei didn't understand, but many of them also half understood.

And the suspicion on Zhao Yunfei's face was gradually replaced by contemplation and amazement.

In the distance, Li Chujie, who was drinking water, glanced here by chance, pursed his lips lightly, and showed a reserved smile.
