Night. In a private room of an upscale and luxurious hotel.

The squad leader Yang Wei was about to cry to a flat-headed young man:

"Brother Sheng, you must be the master for me!"

Yang Wei originally wanted to find the gangster Qian Long and teach Song Fan a lesson, but in the end he was beaten up. Hence the grudge.

After hastily bandaging the wound in the hospital, he didn't go to class in the afternoon, and came here to move the rescuers.

In 1510, Yang Wei described what happened to him in detail.

"Don't worry, brother! I won't let you be beaten in vain! Qian Long, and the one surnamed Song in your class, I'll clean them up for you!" said the flat-headed young man with an expressionless face.

This person's name is Ding Sheng, and he is the senior of Da Yang Wei. used to be the campus handle. Even Yang Wei is willing to be a little brother.

His father, Ding Kekui, is even more black and white. More than half of the entertainment venues in the city are covered by their Ding family. It's a real big brother-level character!

After Ding Sheng graduated, he did not continue to study, followed his father to mix in society, and took over the big hotel.

"Brother Sheng! you are really like my own brother! Little brother toasts you with a cup - no, I have to toast you three times!" Yang Wei said incoherently excitedly.

As long as Ding Sheng is in charge of himself. Song Fan's kid is dead!

"Tomorrow you'll find a way to bring that kid to me. I'll take care of the rest. Ding Sheng put down his wine glass and said calmly.

"Brother Sheng, what are you going to do with that kid?" Yang Wei reminded with some unease, "That kid has been a bit evil in the past two days. The head teacher of our class, as well as Brother Long, even recognize that kid as his father! Brother Sheng, you should prepare more manpower, just in case!"

Ding Sheng said disdainfully: "How many people do you need to deal with a high school student?

As he spoke, Ding Sheng made a phone call.

Immediately after that, from outside the door, a strong man came in, looking from a distance, Kong Wu was powerful, and his appearance was also very fierce and terrifying.

"This is Brother Biao, and my father sent him here to help with the town. Because he was afraid that his son would be young and his subordinates would not be convinced, Ding Kekui specially arranged a strongman for his son to sit in charge.

"Brother Biao, hello!" Yang Wei hurriedly got up and shook hands to say hello. Just one look at this big brother was enough to make him tremble.

Ah Biao nodded faintly.

"Brother Biao, this is my brother, who was bullied at school. Tomorrow, I will ask Brother Biao to take action and teach that kid a lesson!"

Hearing this, A Biao's face flashed with a hint of disdain.

Let a big brother of his level deal with a high school student? It's like killing chickens with a knife, making a big fuss!

But since it was arranged by the boss's son, Ah Biao was embarrassed to refuse. Answered lightly.

Ding Sheng put another bottle of unopened wine in front of Ah Biao. "Brother Biao, show my brother how good you are! ”

Ah Biao didn't say a word, picked up the wine bottle, and pinched it in his hand.

I heard him scream, followed by a crisp click.

An unopened bottle of wine was pinched and exploded by Ah Biao!

What's even more terrifying is that after crushing the wine bottle, Ah Biao's palm was intact!

"Hiss——!!?" Yang Wei was dumbfounded directly, and frequently gasped. 'Oh my god, this is too awesome, isn't it!'

Not to mention a bottle full of wine, even if it is an empty bottle, it is impossible for an ordinary person to crush it with one hand!

"Brother Biao is the Five Tiger Generals under my father!The real practitioner!" Ding Sheng was not surprised by this, and said with a smile, "Brother, is it enough to deal with that evil boy in your class this time?"

"Enough, enough!" Yang Wei nodded frequently, he couldn't help but be overjoyed!

"As long as he dares to come here tomorrow, he will be a waste man in the future!" Ding Sheng's eyes flashed with ruthlessness.

......

On the other side, located in the wealthy area in the south of the city, there is a group of villas.

The Qin family.

Qin Kexin finally waited for the tutor Yu Cheng to be old.

"Yu Lao! You're finally here. Qin Kexin took out Song Fan's notebook with great interest. "I'll show you something, and you'll help me with my palms. ”

"Oh, what's a good thing, take it out and I'll take a look!" Yu Chengsui walked into the study with a smile like a big-bellied Maitreya Buddha.

Whoever sees it may not have imagined that this kind old man was once a professor of mathematics at Qingbei University in Yanjing, and a Taishan Beidou-level figure in the Chinese mathematics community.

After retirement, the leaves returned to their roots and returned to Jiangnan for retirement. I had nothing to do, but the Qin family was kindly invited and hired as a tutor with a high salary.

said that he was a tutor, but in fact, he only came to Qin's house once a week to give Qin Kexin a guide in mathematics. But even if it is a lesson a week, Qin Kexin has benefited a lot.

"Old Yu, look at this notebook from my tablemate. In today's class, he spent two classes proving Goldbach's conjecture! I can't understand these formulas, Yu Lao, you have come to see it. ”

After hearing this, Yu Lao couldn't help laughing. What did you think it was, but it turned out to be an ignorant and fearless young man who wanted to challenge the three major problems in the world of mathematics?

To tell the truth, Yu Lao has been teaching for many years, and there are not 1,000 students per semester, but 800 students who came to tell him and proved Goldbach's conjecture.

Even when Yu Lao himself was young, he wasted a long time and checked his calculations. Fantasized about being able to prove the world's problems and become famous overnight.

However, it was the first time that a high school student had heard of Goldbach's conjecture.

But even so, Yu Lao is too lazy to look at it anymore, it is nothing more than those old steps, and all kinds of logic in them are chaotic.

"Tell that classmate tomorrow that you will study hard in the future and don't waste time on this. Yu Lao kindly persuaded.

"Old Yu, just take a look. Qin Kexin pestered Yu Lao, and she had to let him look at it.

"Okay, okay, I'll just look at a page and help him analyze and analyze what the mistake is. Yu Lao took the note.

At a glance, the first formula made Yu Lao's eyes light up and a refreshing feeling.

"Huh, it's kind of interesting!" Song Fan's proof idea was very novel, which Yu Lao had never seen before.

After continuing to look at it, Yu Lao's expression became more and more solemn and shocked.

Originally, he said that he wanted to read a page, but as a result, Yu Lao looked through the notes faster and faster, and in the end, even his hands were shaking.

"Old Yu, how is it ......" Qin Kexin noticed the change in Old Yu's expression, and couldn't help but be a little surprised and surprised.

Originally, Qin Kexin didn't expect much, and didn't think that Song Fan, a high school student, could prove anything. I just kindly wanted Yu Lao to help me take a look and give him some advice.

The result was unexpected-

Yu Lao waved his hand again and again, signaling Qin Kexin to be quiet. And turned around, his shoulders shaking.

When he turned to the last page, Yu Lao looked up to the sky and sighed, and left two lines of tears.

"The sky has eyes, and in the past hundred years, my Chinese mathematics community has finally become a genius again...... Even if Chen Jingrun, Hua Luogeng, and other senior masters are resurrected, it's nothing more than that......"
