"53 seconds 27!" This is the time finally displayed on Guo Jianfeng's mobile phone.

According to Lao Liao, this is not a standard venue, so the score can be improved by at least 0.5 seconds. Guo Jiafeng noticed the child's shoes. Jiefang shoes, which have been hard to find in the city, do not seem to fit well, so he changed them to something suitable.

It is entirely possible to improve your running shoe performance by 2 seconds.

This child is obviously still malnourished. If his nutrition keeps up, his endurance and explosive power will definitely increase!

The most important thing is that this child has obviously not received formal training, and his most basic starting posture is not standard! This score can definitely be improved. As long as he is willing to train hard, he will not have a big problem in becoming a national first-class athlete in the future.

You must know that the national first-level athlete's 400-meter time requirement is only 49.60 seconds.

This made Guo Jianfeng find Wang Yufei more pleasing to the eye. At first glance, he seemed to be an honest kid who was willing to endure hardships.

"The results are good, don't run away, take a good rest and go play!"

"Well, then I'll go back to the classroom to read first!" Wang Yufei nodded and said obediently.

After running these two laps with all my strength, the urge to exercise in my mind gradually disappeared, and it was time to go to the classroom and read a book. Although I definitely couldn't understand most of the things.

"You're all dismissed, too. Go back to the classroom. The monitors of each class will go to Teacher Qu to collect your books later!" Principal Liao shouted.

As soon as he finished speaking, the school bell rang, and a bunch of children dispersed in a hurry. The playground, which was so lively just now, suddenly became deserted.

…

"It's a good seedling!" Guo Jianfeng emphasized again.

I really like him from the bottom of my heart. This physical quality is enough to inherit his legacy.

"By the way, how were his grades in cultural classes?" Guo Jianfeng asked again.

But as soon as the question came out of his mouth, before Principal Liao could answer Guo Jianfeng shook his head: "Forget it, it's useless to ask you. There are six classes, three main courses and only five teachers. It's strange that the results in the cultural class are good.

How is his understanding? Can he learn it?"

"Hey, Guo Zi, why don't you bring someone you look down upon so much!" Principal Liao twisted his mouth angrily and wanted to argue, but thinking about the huge gap between rural schools and provincial schools, he finally became discouraged and thought about it.

After thinking about it, he answered truthfully: "What do you think of Wang Yufei? After all, he is already sixteen years old and is still in elementary school. He has missed the best time for his brain to receive knowledge. Naturally, his grades cannot be ideal and he is not very smart.

Let me think about it, in last year's final exam, he was at the bottom in math."

"Look, I can't chat with you. I'm a pretty smart guy no matter how I look at it, so why do I turn out to be a fool when it comes to you? No, I can't listen to you. You'd better wait for me to find out. Well, why don't I talk to you today?

I won’t go back and take a good look at this little guy." Guo Jianfeng said with great interest.

"Hey, you changed your mind? Wait, why are you observing this kid? What do you think?" Principal Liao said in surprise.

"What do you think of me adopting this child?" Guo Jianfeng said in surprise.

"You're crazy!" Principal Liao rolled his eyes.

"What are you crazy about? It's not like you don't know that Han Qian and I have always wanted to have a son. You also said that this little guy is an orphan, and his uncle and aunt are not good to him. And I think this child is destined to me!

"

"I want to fall in love with you? What should you do with your daughter?" Principal Liao asked angrily.

"My daughter has always wanted a brother!" Guo Jianfeng said firmly.

"I……"

"No, mine. Let me study the adoption law first. You can find a time for me later and we can have a good chat with this little guy."

…

In the classroom, Wang Yufei is immersed in the ocean of knowledge.

He could understand the mysteries that were once incomprehensible in books, and he could understand them instantly after reading them once.

What was even more exaggerated was the English book that had just been handed out. He flipped through it casually and felt that he had memorized everything in it.

This is definitely an illusion!

Just close the book and think about it however you want, but what you just saw is still vivid in your mind.

Wang Yufei picked up the Chinese textbook again without believing in evil...

Very good, I finished reading it again in less than twenty minutes, and all the articles have been engraved in my mind.

Well, the children who have to swear under the red flag every Monday in the new century must believe in science and not evil!

So Wang Yufei picked up the math problem that troubled him the most.

It is not an ordinary textbook, but a legendary elementary school mathematics Olympiad question bank.

He was not good at math, so when he learned from the teacher that the textbooks were just basics and that the elementary school math Olympiad questions were really difficult, he went to the school library to borrow them.

It’s not that I want to challenge the impossible, but half-year-old children are curious about what the most difficult math problem looks like.

I studied it for two days during the winter vacation and it was really difficult. I almost tore through the math textbook at home and still can’t do it.

But what's going on today?

Why did the questions suddenly become easier?! Even the answers to many questions appeared in his mind at a glance, and the steps to solve the questions were pushed out in an instant.

Not believing the numbers that appeared in his brain, Wang Yufei tried to pick up a pen and start checking...

There seems to be no problem!

Wait, when did this formula get into his head? Well, I think I saw it in a textbook before, so this is how it is used.

For a time, Wang Yufei became addicted to answering questions. He was completely immersed in the ocean of knowledge and could not extricate himself.

Sitting in the last row, he didn't even notice that the teacher had finished class. His classmates were already running to the playground outside to play in cheers. He was the only one left in the classroom holding the newly issued textbooks and writing hard.

Written by Ji Shu.

When Principal Liao was worried and couldn't find Wang Yufei in the square, and finally took Guo Jianhua into the third-grade classroom, this was what he saw.

…

"Wang..." As soon as Principal Liao uttered a single tone, he was stopped by Guo Jianfeng: "Don't disturb the child, go see what he is writing."

The two adults quietly walked to Wang Yufei from the back door.

Principal Liao was instantly stunned by the dense numbers and formulas on the math sketchbook.

Huh? When did this little guy's handwriting become so beautiful?

Wait, these questions were all done by Wang Yufei?

Especially the question we are working on: the single digit of a certain n-digit number is 6, move 6 to the first position of the number, and keep the other digits unchanged, and get a new n-digit number. This new number is the original n-digit number.

4 times the number, what is the minimum n number of digits that satisfies the above conditions?

This definitely can’t be a question in the textbook, right?

This little guy actually solved it step by step?

This problem-solving idea...

Lao Liao suddenly felt his shoulder being tapped.
Chapter completed!
