Shen Qi spent 106 days in the United States, and in terms of his environment, the United States is a democratic, tolerant, harmonious, and safe country.

There had been no shooting, and no gunfire had ever been heard.

The people of the world are united, and non-white people have equal status with white people.

There are no drugs here, and people love running, exercising, and all kinds of fitness activities.

There is no need to worry about unemployment, and everyone is busy and fulfilling.

Freedom of speech here, you are respected because you have extraordinary wisdom and good cultivation.

United States of America, American-Dream, you prosper by the power of God.

Until the 106th day, Shen Qi thought so, because in these 106 days, he had never taken a step towards Princeton.

However, on the 107th day, Shen Qi changed this mind, and he was robbed in New York.

The armed robbery took place at night, and the white youth holding a glock was emaciated like a zombie, and he couldn't stop sniffing.

"I need some money, I don't want to kill. The white youth said only one sentence, with fierce eyes and no regard for life.

Then Shen Qi gave him all the three hundred dollars in cash in his wallet.

Shen Qi confessed and did not put up any resistance, according to his observation, once he made a gesture of resistance or a move that seemed to be resisting, the robber would shoot without hesitation.

"New York, the most prosperous city in the United States, is heaven by day and hell at night. Shen Qi poured champagne in the hotel's restaurant, suppressing his shock.

"I told you a long time ago, don't leave the hotel at night. Mary complained, "I'll bring you alive to New York, and if I return to Princeton with a corpse, Professor Mueller will kill me." ”

New York is not far from Princeton, and Shen Qi and Mary arrived in New York this evening, where they will attend a math seminar at Columbia University tomorrow morning.

After checking into the hotel, Shen Qi went downstairs to get some cash, and then he was robbed, outside the Wells Fargo Bank next to the hotel.

In fact, this is Shen Qi's second visit to New York, the first time was on August 15, when he flew to New York from China and went straight to Princeton without stopping.

Shen Qi finally stepped out of the Princeton gate, this was the first time he had left the university, and the accompanying person was Mary.

I wanted to see the great rivers and mountains of the United States, but when I saw a yarn, I was robbed when I went out!

Shen Qi died of depression, the United States is estimated to be a little better in small cities like Princeton, the big cities outside are too chaotic, society, society, American society can't afford to provoke.

"Hey, don't drink it, hey!" Mary stopped Shen Qi from continuing to drink, and she snatched Shen Qi's wine glass: "You can drink as much as you want after the meeting tomorrow, but tonight is enough." ”

"I'm just thirsty. Shen Qi spread his hands and said, then got up: "All in all, thank you for your concern, see you tomorrow." ”

The next morning, Columbia University.

Shen Qi and his colleague Mary arrived at the meeting site of the "Ivy Number Theory Symposium" on time.

The conference gathered number theory experts and scholars from eight famous universities in the northeast of the United States, and the participants had extensive exchanges and profound discussions on number theory issues such as the Riemann conjecture, the Goldbach conjecture, the Birch-Swinnaton-Dale conjecture, and the Walsh conjecture.

The academic atmosphere of the conference was very strong, and the participants expressed their opinions one after another.

Professor Morris from Pennsylvania spat at Professor Jeffers at Cornell and walked away angrily.

Professor Jeffers allegedly stole Professor Morris's unpublished manuscript and shamelessly appropriated his work for himself.

Shen Qi was taken aback, he didn't know, he was shocked, there is also plagiarism in the American academic community?

Subsequently, Shen Qi made a speech, and the meeting was able to restore normal order.

The Riemann conjecture, the Goldbach conjecture, and the Birch-Swinnaton-Dyer conjecture are still in the conjecture stage and are inconclusive.

Only Walsh's conjecture was proved by Shen Qi, who spoke on behalf of the Princeton Department of Mathematics and was recognized and praised by most of the delegates.

"If V3 is a square number, then for any k greater than 1, V2k+1 is not a square number, and the equation (t+1)X^4-ty^2=1 has at most two sets of solutions such that X and Y are positive integers......"

Shen Qi wore a black suit and a red tie, he held a PPT flip pen, talked eloquently, and answered a few doubts from the delegates from time to time.

Shen Qi's speech was very exciting, the logic was clear, the statement was rigorous but not boring.

Mary listened attentively, and she seemed to have forgotten the unpleasant troubles of her family, and only the profound mathematics could give her a temporary peace.

Mary couldn't help but stare at Shen Qi, the young graduate student of the Department of Mathematics of the University of Mathematics showed a maturity and stability far beyond his peers in front of mathematics, just like a senior professor who had been in the industry for many years.

Mary didn't have any trouble with Shen Qi, because Shen Qi's level had surpassed her, and he continued to accelerate.

Since passing the test of the big club of the mathematics department of the general university, Shen Qi has become more confident, he is an unarmed Chinese student on the streets of New York, but he has a powerful homemade weapon in the field of mathematics.

"Thank you Mr. Shen of Princeton for his speech, the coffee break is up, and I will ask Mr. Shen to continue his speech after 15 minutes. The moderator said.

During the tea break, Shen Qi finally met his former idol Gong Changwei.

Gong Changwei, a mathematics professor at Columbia University and an expert in number theory, was a few minutes late and didn't make it to meet Shen Qi before the meeting.

"Great God, I finally saw you in real person!" Shen Qi hugged Gong Changwei as if he was familiar, this was the first time he spoke Chinese to someone in American society.

"Don't, you're God. Gong Changwei smiled, "I've heard of Shen Qi, your senior brother Yan, I'm a fan of you now." Walsh guessed that I had studied it for years, but I didn't expect it to be proven by you. ”

"Let's get together another day and be with Yunshen. ”

"Yale is very close to New York, and we will keep in touch in the future, hoping to have opportunities for cooperation in the future. Teachers out of Yan Datongmen should take care of each other. Gong Changwei handed Shen Qi a business card and said: "If you have something to call, I have been in the United States for many years, after all, I am more familiar with the situation than you, and you can ask me if you have any doubts in academic and life." ”

"Okay, keep in touch. Shen Qi and Gong Changwei exchanged business cards, and the senior brothers and brothers of the Department of Mathematics of Yan University successfully met in the largest city in the United States.

I'm very happy that I finally met a Chinese fellow in the United States, which is kind of connected with the organization. Shen Qi was full of energy and prepared to enter the conference hall to start his speech in the second half.

Shen Qi attaches great importance to this "Ivy Number Theory Seminar".

Although there were only a few dozen participants from eight universities, and it was not a grand symposium in all fields of mathematics, Shen Qi was happy to participate in this kind of academic seminar, expanding his academic profile outside of Princeton, which has now expanded to the New York area and surrounding Ivy League schools.
