During lunch time, Sun Erxiong did not discuss any specific mathematical problems with Shen Qi, and they spent most of their time chatting.

"Shen Qi, what profession did your parents work?"

"My dad does some small business, and my mom is a doctor."

"It seems that your family is in good condition, where are the grandparents who are?"

"Professor Sun, do you have to check your household registration when you come to Yanda? My grandparents are both workers, and my grandparents are both doctors."

"It's great, it's good, your father is in a good position, and your mother's medical family, so why did you choose mathematics?"

"If you learn mathematics, physics and chemistry well, you will not be afraid of traveling all over the world."

"It's an official answer, but I believe it. Are you used to life in the north?"

"Even if I have a lot of hardships on my journey to study, I have to go on. In fact, the north is pretty good, it's just dryness. I haven't had any bowel movements for three days and can't pull it out."

"Shen Qi, I'm eating dumplings!" Sun Erxiong got stuck in his throat, making it difficult to get ahead.

"Professor Sun, am I eating too?" Shen Qi was not abnormal.

"You are cruel, I'm leaving." Sun Erxiong wiped his mouth and stood up and left.

"Hey, Professor Sun, don't leave..." Shen Qi watched the fat old Sun who was 200 kilograms gradually get farther and farther away. They divided three kilograms of dumplings, Shen Qi ate one kilogram, and Sun Erxiong ate two kilograms.

All afternoon, Shen Qi painted pictures on draft paper.

In fact, Shen Qi also felt some of his problems in mathematics. In the past eight months, he has read a large amount of mathematical literature, journals, papers, and mathematics knowledge, and has a certain ability to apply it comprehensively, but there is still a gap from the state of being able to open and close and freely. This has led to him getting into misunderstandings in some mathematical problems and being stubborn.

"Forget it, I won't draw it anymore, it's a headache." Shen Qi stopped to make a picture and rubbed his temples. He drew 101 kinds of graphics in the afternoon, and he could take it out to sell it for money if he bound it into a book.

Cramped, the door of the small house opened, and Sun Erxiong came into the house with a large bag of buns.

"It's almost six o'clock, Shen Qi, let's have buns for dinner." Sun Erxiong put the buns on the table, and it must be four or five kilograms.

Shen Qi pushed 101 pieces of white paper with graphic drawings in front of Sun Erxiong, looking very tired: "Professor Sun, I have drawn 101 answers, see which one is what you want."

Sun Erxiong had a bun in his left hand and a white paper quickly flipped through the right hand. He turned to the 12th piece, pulled out and said lightly: "Just this one, congratulations to Shen Qi, the answer is correct."

"Professor Sun, don't you have to check the one behind?" Shen Qi asked.

"No need." Sun Erxiong placed the 12th white paper on the desktop.

The pattern on the white paper is a regular hexagon with a circle cut inside, and three lines are made in the regular hexagon, just passing through the center of the circle.

"This... Brianxion's theorem is done?" Shen Qi couldn't believe it was so simple?

(Note [2] Brianxiong Theorem: A common point of the connection between three simple hexagrams of three simple lines connected to the vertices that are cut off from a non-degraded secondary curve. This point is called Brianxiong Point)

"That's right, what I want is the supplementary drawing ordered by Brianxiong." Sun Erxiong nodded and ate a pork and green onion bun.

"Ah..." Shen Qi looked up at the ceiling and sighed desolately. I worked hard to draw pictures for the whole afternoon and thought all day long. All you want is a Brion Point?

"Shen Qi, look, the left picture on the blackboard is based on Pascal's theorem." Sun Erxiong walked to the blackboard, knocked on the left picture, and said: "You only need to give the projective geometric expression of Brianxiong's theorem, which is enough. In fact, the logic is not difficult. Pascal's theorem and Brianxiong's theorem are mutually opposed."

"For example, Shen Qi, you spread your palms and see the palms, then turn your palms and put your backs upwards, and then complete the answer. It's so easy. However, in order to complete this easy palm steps, you first do a warm-up exercise, then run five kilometers, and exhaust yourself. In fact, the large amount of exercise before the palms is futile, not to say that it's useless, and it's unnecessary."

"Damn..." Shen Qi spread his palms, facing the palms up, then turned his palms, and the back of his hand was facing up, and did it again, one, two, three, four.

"So Shen Qi, do you realize what your problem is?" Sun Erxiong asked.

"I'm afraid I'm going to be a demon." Shen Qi's face was solemn. The cultivation in the field of mathematics may have reached the tribulation period, and further entered the fairy world, and take a step back and hit the sky with thunder.

"Have you read martial arts novels, Shen Qi." Sun Erxiong suddenly talked about a seemingly irrelevant topic.

"Of course, Jin Guliang Wen is familiar with it."

"Then let me ask you, is Zhang Wuji's internal strength strong?"

"Zhang Master Zhang has the Nine Yang Divine Art to protect his body, and his internal strength is as strong as he can."

"What are the specific tricks that Zhang Wuji often uses?"

"He... doesn't seem to have any specific tricks? He can do it for a few moves of the universe and kill the opponent in seconds. This is an operation of the stream of consciousness."

"So Shen Qi, what did you understand from Zhang Wuji?"

"Could it be... Could it be... the highest level of martial arts is that there is no move, and if you can't kill it within three moves, you will lose if you can't kill it?" Shen Qi trembled inexplicably.

Sun Erxiong smiled and said, "The same is true for basic mathematics. The simpler, the more complex, the more complex, the simpler it is. Can you understand it?"

After staring at the dog for a minute, Shen Qi suddenly realized: "I understand, I understand! Thank you Professor Sun, I have learned new skills! I know how to write my problem-solving skills guide! Expert, Professor Sun, you must be a top expert, like Zhang Sanfeng!"

"I'm not a master, just an ordinary teacher." Sun Erxiong waved his hand and said, "You are still nine months away from officially reporting to Yan University. The directional advice I will give you in these nine months is that you don't have to add new reading content to mathematics, just review the mathematical theories you have learned by yourself. After this mathematical camp, Shen Qi, you should return home and spread the breadth of knowledge and expand the coverage of knowledge. Basic physics and basic computer theory are better supplements."

"Even the entry-level architecture, painting principles, and musical foundations, you can try to contact us if you have time. Believe me, this will help you to enter a deeper level of mathematics. We at Yan University never cultivate nerds, we are the creators of academic masters. We only know how to do questions but have no thoughts. Even if you get a diploma from Yan University, you are nothing more than a senior worker."

Shen Qi was shocked by it: "I understand. Listening to Professor Sun's words is better than reading for ten years."

"Next September, I hope to see a better Shen Qi." Sun Erxiong smiled, took out a bun from the bag and handed it to Shen Qi: "I'm done with what I should say, eat the buns Shen Qi."

Shen Qi took the buns and ate them very delicious.

At this time, the wall clock on the wall ticked, and Shen Qi turned his head and looked, "Oh, it's six o'clock!"

"Professor Sun, you will definitely see a better Shen Qi in September next year, but now, I have to leave." Shen Qi grabbed two buns and stuffed them into his pocket, looking hurriedly leaving.

"I'm so anxious, where to go? Do you need me to send you?" Sun Erxiong took out his car key.

"I have a good brother to compete soon."

"Then Shen Qi, you can take the subway by yourself. You will need to be at least two hours on the road when you drive to Capital Sports University."

"I'm leaving, see you tomorrow!" Shen Qi ran away.

To be rushing to death, Shen Qi arrived at the Capital Sports University Sports Stadium at 6:30, and the National U19 Track and Field Games were held here.

"Fortunately, I caught up. Which one is Xu Rui?"

In the audience stands, Shen Qi looked around and saw eight young players lined up at the 100-meter starting line on the plastic track.

The muscular guy in the fourth lane was wearing a blue sportswear and the player with the words "Nan Yue Province" on his back was Xu Rui.

Bang!

At this time, the starting gun fired and the men's 100-meter running final of the National U19 Track and Field Games began.

Xu Rui's departure was very bad. He was obviously slower than other players to start, and as soon as he set off, he fell to the last place.

During the acceleration run and the journey, Xu Rui ran wildly like a desperate man, and he chased more than a few people to the third position.

"Rare on Xu Rui, and explode two more!" Shen Qi was nervous when watching the game. He knew that only the 100-meter champion was meaningful to Xu Rui. Second and third were equivalent to failure.

However, the two players who rushed to the front were very strong. Even if Xu Rui pressed the gun to start, he might not have the absolute chance of winning the championship, let alone his starting lineup was a bad match.

The red shirt player in the fifth lane was the first to cross the line, and Shen Qi covered his face and dared not continue watching.

In the end, the results were shown on the big screen that the player from the Capital Team won the men's 100-meter championship with 10.79 seconds, and Xu Rui ranked third in 10.90 seconds.

Shen Qi had to watch it even if he didn't look at it. In the field, Xu Rui, who had finished the game, sat on the ground with his butt. He looked dull and lost to the extreme.

"Oh, it's not easy to win a national championship." Shen Qi rushed to the competition site. He failed to witness Xu Rui's victory with his own eyes. All he saw was failure. According to Xu Rui, Shuimu University only accepted national championships in various individual events, so it was a bit unlucky for Xu Rui to be admitted to Shuimu University through his sports expertise.
