Yanjing City in the evening is very crowded, and it took a long time for the Mercedes Benz to find a KFC with a parking space outside the Fifth Ring Road.

Recently, Han Sen feels that he is a little nervous, he is sorting out Fermat's theorem, writing new cryptography, this world Fermat's theorem has not been solved, which means that no scholar has perfected modern cryptography on the basis of Fermat's theorem, everything needs to be perfected by Han Sen himself, recently his eyes only have numbers, equations, and even on the road, all distances and speeds will be measured by the eyes, and then processed in the brain, there is no driving pleasure, it is all boring rationality.

And Qin Jing was like a cure, looking at the girl in front of him who was gnawing on chicken legs, Han Sen only had her in his eyes, and all reason disappeared without a trace.

Qin Jing will make Han Sen remember that there is not only precise rationality in the world, but also beautiful sensibility, and many times when driving, slamming on the accelerator, slamming on the brakes, and opening up to insult are also an important part of life.

In KFC, nibbling on the chicken wings without skin in his hand, Han Sen pretended to be very puzzled and said, "Why do you say that this KFC's Orleans roast wings are so strange, why don't they have skin?" ”

"Hee-hee." Qin Jing smiled and gnawed, it's good to have a boyfriend.

Han Sen nibbled on the skinless chicken wings and asked, "How are you in the hospital?" Has anyone bullied you? ”

"Tired~" Indeed, even if he was just a graduate student, Qin Jing in the hospital felt extremely tired.

"Is it good for me to raise you?" With 100 million, Han Sen instantly had a lot of confidence.

"Not good."

......

Bidding farewell to the endless sea of books in the school and the busy internship in the hospital, a young couple chatted nonsense, which was a very beautiful moment for both of them.

.....

It soon got dark, and the number of people in the KFC restaurant increased one after another, and a very plainly dressed mother led two clean little girls into KFC.

"Hello and welcome." The clerk's polite greeting startled the simple mother, this was her first time in such a "high-end" place, the eldest daughter was great, she took a first place in the exam, and she promised the KFC that her daughters dreamed of.

But look at the expensive price list, every meal in it is enough for the family's living expenses for a day.

Finally, looking at the two long-awaited daughters beside her, my mother gritted her teeth and ordered a burger and a pair of Orleans grilled wings, and the beautiful KFC waiter was very good, and did not ask: "Just order food, don't you want to drink?" In fact, such a simple sales sentence is enough to crush this mother.

In a huge city, no one will pay attention to this simple mother, and the manager of the store secretly added a piece of chicken wings to her, but this mother didn't know it, because she thought it was a luxury to buy such three chicken wings for 11.5.

There were a lot of people in the restaurant, and my mother took her two daughters around and came to Han Sen's side, probably thinking that the beautiful Qin Jing was very kind, she didn't open her mouth to Han Sen, but smiled at Qin Jing and asked, "Girl, do you have someone sitting here!" ”

"No, no, I'm sorry!" Han Sen hurriedly put away the backpack that had been placed randomly.

"Thank you!" After a brief thank-you, the simple mother greeted the two daughters: "Come, sit." ”

The little sister excitedly picked up the hamburger and handed it to her mother: "Mom, you eat!" ”

"Mom doesn't eat it!" Of course Mom won't eat it.

Then the younger sister handed it to the elder sister: "Sister, sister, you eat!" ”

The sensible sister swallowed a mouthful of saliva, got up, and reprimanded her sister: "Sister, look at your hair is messy." ”

My sister happily ate the hamburger, and my sister carefully arranged her hair.

Qin Jing gave Han Sen a look.

Han Sen got up, walked to the ordering table, and came back with a large pile of all kinds of family buckets, nothing, each continuing with his own.

After the little girl finished her burger.

Qin Jing got up and said to the beautiful young lady with a smile: "Hahaha, little friend, is it okay to do my sister a favor, this stupid big brother ordered so much at once, my sister really can't eat, you can help my sister." ”

Han Sen said he was hurt.

The little girl was a little overwhelmed.

The mother nodded, the little girl didn't know what to do, but a mother knew that this was a charity, for a mother, other people's charity was very hurtful to self-esteem, which showed her own incompetence, but life has already worn out her self-esteem, and the only thing left is helplessness.

The little girl wanted to say "thank you, sister", but her childish little head couldn't turn around, as if she was doing her sister a favor, as if she shouldn't say thank you.

......

The Mercedes Benz drove towards the center of the city at night, and Han Sen said with a smile: "Why do you say you are so good, come and let me kiss it!" ”

A meal of KFC is dismissive for many people, but for many others it is a very luxurious yearning, life, is always the most fucked up, so we must work harder to change our lives.

......

When Han Sen and Qin Jing were tired, on the other side of the ocean, the new issue of Princeton University's "Annals of Mathematics" was printed and began to be shipped out.

"I really think there's a good chance that this kid has solved Fermat's theorem."

In his office at Princeton University, Lambert read the article on the front page of the Annals of Mathematics again: "A Brief Analysis of Fermat's Great Theorem: The Encryption of Prime Factors in Large Integers", and he had a hunch that Hansen had probably solved Fermat's Great Theorem, which was a great innovation.

Closing the newly printed Annals of Mathematics, Lambert opened the American Economic Review published by Harvard University, and once again flipped to Hansen's "The Impact of Cross-regional Internet Clearing and Payment on the World Economy."

......

Princeton University, since its establishment has a history of more than two hundred years, more than two hundred years of history, means a long time of sedimentation: Einstein came here as a visiting professor, and studied general relativity here, and worked here as the father of the atomic bomb Oppenheimer, the father of computers von Neumann, Gödel who shattered the beliefs of mathematicians for more than 2,000 years, and the Chinese familiar Yau Chengtong, Chen Shiingshen and Yang Zhenning.

A university, the reason why countless students yearn for it, is because of the imprint left by this big bull, hundreds of thousands of students apply for this school every year, and in the end only two thousand lucky people will be admitted, compared to the Chinese national examination, the acceptance rate is still okay, countless Chinese students are going forward to challenge, their initial desire is to return to the country, but time, will change a lot.

In a teaching and research room in Princeton, several Chinese students maintained their own small circles, and a Chinese student named Yao Ruzhi opened the latest "Mathematical Yearbook" and was stunned: ", our Tsinghua article." ”

"I'll see." It was still very exciting to hear the disappearance of his alma mater in a foreign country, and immediately a classmate snatched the book in Yao Ruzhi's hand and took a look: "Fermat's theorem? So powerful! Sun-Han, isn't this Senior Han Sen? Did he return home? ”

Then a female student said: "It's impossible, I heard that the "Annals of Mathematics" has offered him, and he has worked in the Federal Reserve and the International Monetary Fund, what a good future in the United States?" Why do you want to go back to China! ”

Yao Ruzhi thought for a while and said: "It should be back to China, Senior Han Sen has only worked in the Federal Reserve for one year, and the Federal Reserve said that it could provide him with Sam's Country nationality, but Senior Han Sen refused!" Then, the Federal Reserve rejected Senior Han Sen. ”

As soon as she heard that it was Sam's Country nationality, a girl immediately sent out a little star in her eyes: "Wow! It's not that a green card is an authentic nationality! He refused, so stupid! ”

"Huh? Foolish? You're not stupid, you can write this paper! Yao Ruzhi, who is about to graduate, has decided that he is going to follow in the footsteps of Senior Han Sen, and he wants to return to China.

At this time, Dr. Sam Guo, who had finished reading Han Sen's dissertation in the teaching and research department, asked the excited group of Chinese students, "Is this Sun-Han from your Chinese?" ”

"Of course!" Several Chinese students replied proudly in unison, and a sense of national pride arose.

"It can't be some Sam's country man who changed his name!" Sam Country's Doctor spoke.

"Hehe, that's sour." This feeling is good, this is the envy of Chi Lulu!
