After returning from Shanghai, Lu Zhou put all his energy into preparing for next month's academic conference. The paper on the study of the distribution law of Mersenne primes was turned out by him and read again and again, and all kinds of places that might have been provoked and questioned were rehearsed by him I don't know how many times......

After all, to a certain extent, it represents the honor of the university, and Kim University is also quite supportive of his trip to Princeton to participate in this academic conference, not only chartering him a round-trip ticket, but also allocating $2,000 from the treasury to him.

In addition, Dean Qin also generously promised Lu Zhou that if the $2,000 was not enough, he would be reimbursed again with the invoice after he returned.

However, Lu Zhou felt that with his own consumption level, the 2,000 dollars would definitely be enough.

The accommodation and meals were all solved by the organizers, and in addition to the transportation expenses for travel, he couldn't even think of a place to spend money.

In this way, time passed day by day, and finally it was January 29th.

Professor Tang personally drove Lu Zhou to the airport.

"When you get there, stay safe, don't go to a place with fewer people, don't get into the black community, see people dressed strangely walking around......"

Along the way, Professor Tang was telling Lu Zhou about safety, as if he was not going to North America, but North Africa.

Although I know that the professor is for his own good, and he says so many things out of the concern of the elders for the juniors, this concern is too much, and it becomes pressure.

Lu Zhou said with a smile: "I know, professor, I will definitely come back alive!" ”

As soon as these words came out, Lu Zhou regretted it a little.

Wait, isn't this a flag?!

"What dead or alive, how do you speak?" Hearing these unlucky words, Professor Tang was angry, and slapped Lu Zhou on the back of the head with his free right hand, "Boy, listen, I have greeted my doctoral student over there, his name is Luo Wenxuan, you can call Senior Brother Luo." When the time comes, you get off the plane and take the bus directly according to the route I told you. When you get to Princeton, he'll pick you up at the station over there and take you straight there! ”

Hearing this, Lu Zhou touched the back of his head and sighed sincerely, "Professor, your students are really all over the world." ”

"Hehe, so-so."

Old Tang smiled.

It can be seen that the old gentleman is still quite proud.

Soon arrived at the destination.

Dragging his suitcase into the airport, Lu Zhou waved goodbye to Professor Tang in the waiting hall, and then turned around and stepped towards the security checkpoint.

With a white line drawn across the blue sky, it gradually faded away.

In this way, Lu Zhou embarked on his trip to North America......

……

Situated between New York and Philadelphia, Princeton is a country city with a unique character in the middle of a bustling capitalist world.

It's quiet, elegant, laid-back, and a great place to learn...... But at the same time, this small place also takes one of New Jersey's great features to the extreme: transportation and its inconvenience.

In this country where the driver's license is used as an ID card, there are very few people who do not have their own car, and it is precisely because of this travel habit that it is simply difficult to move an inch without their own car in this country.

According to the transportation plan recommended by Old Tang to Lu Zhou, you have to change trains at least twice on the way from Philadelphia to Princeton.

When he was on the plane, Lu Zhou took the map and pondered the transportation route for a long time, but finally gave up and decided to take a taxi.

Anyway, the school reimburses the travel expenses, and he doesn't need to save money.

With such an idea, Lu Zhou suddenly didn't bother to study the bus route anymore, and fell asleep directly.

After nearly 25 hours of flight, I woke up a few times in the middle of the flight, and the plane finally landed at Philadelphia International Airport.

Because of the time difference, the sky was bright at this time.

Passing through the bustling crowd, Lu Zhou left the airport quickly with his suitcase and stopped a taxi directly outside the airport.

Coincidentally, the driver was a Chinese, with a bit of Jiangcheng's accent in Mandarin.

As soon as he heard Lu Zhou speak, the driver's uncle's eyes lit up.

Although Hubei Province has different tones for ten miles, and the cultural identity of each city is not high, but out of this country, then everyone is a fellow countryman!

Enthusiastically helping the landing boat put the luggage in the trunk, the driver sat in the driver's seat and asked with a smile.

"Studying abroad? Where to go? ”

Lu Zhou didn't explain much: "Princeton University, do you want to go outside the city?" ”

"Hehe, if others don't go, fellows still have to go," the driver grinned, put his watch on the table, reminded Lu Zhou to fasten his seat belt, and then started the car.

may be because it is rare to meet fellow villagers, this driver uncle talked a lot, and talked with Lu Zhou from the international situation to the daily life of firewood, rice, oil and salt in the United States, and finally talked about the unavoidable safety topic.

“…… In fact, it's not as exaggerated as your teacher said, a place like Princeton is considered a country, and the security in the countryside here is much better than in the city, but it's best not to walk at night, especially if you don't have a car, it's easiest to be targeted. It's okay to say that if you encounter a robbery, you will generally be fine if you hand over your wallet, and you don't want to stick to a big case if you are not a vicious fugitive, but if you encounter a robbery, heh......"

Lu Zhou smiled: "Men don't have to worry about this, is there still that kind of female robber?" ”

The driver's uncle grinned: "Hehe, that's not necessarily a woman." ”

Lu Zhou: ???

What the heck?

Are foreigners so social?!

And this "hehe"......

I always feel that this uncle seems to have a story......

About an hour or two drive to the city of Princeton.

The driver looked like he had been here many times, and drove to the gate of the university with ease.

"My name is Zhang Hai, this is my business card, you can call me if you need a car in an emergency."

Helping Lu Zhou put the suitcase down in the trunk, the driver uncle threw down a business card, and then got in the car and left.

Dragging his suitcase, Lu Zhou stood at the gate of Princeton University for a while, always feeling as if he had forgotten something.

After thinking about it for a while, he suddenly remembered that Professor Tang and the Senior Brother Luo he was talking about seemed to be waiting for him at the gate of a certain train station.

With a subtle embarrassment in his expression for a moment, Lu Zhou took out the phone from his pocket, replaced it with a ten-day temporary calling card bought by a certain treasure, and quickly called Senior Brother Luo, saying sorry and letting him not have to pick him up Yunyun.

Fortunately, the call was made in time, and the others had just plugged in the car keys and had not yet set off, so they did not cause much trouble to others.

After hanging up the phone, Lu Zhou looked back at the school gate in Princeton and then at the nearby street.

"The hotel arranged by the organizer seems to be called ...... A Princeton hotel? Where is this hotel? ”

The invitation seems to have an address on it, but it's tucked away in a suitcase.

Want to open it here?

What a troublesome feeling......

Just as Lu Zhou was looking around at the school gate, a foreign lady wearing a gray windbreaker and a red plaid scarf tied around the neckline, blonde hair and blue eyes happened to pass by.

Noticing the suitcase next to Lu Zhou, her eyebrows raised suspiciously, and she asked.

"Freshmen?"

"No, I'm not a student here," Lu Zhou smiled embarrassedly and quickly asked, "May I ask about the mathematics academic conference here...... How to go? ”

The girl stared at Lu Zhou and looked her up and down.

"Name?"

"Lu Zhou."

"The Mathematical Society of the Federal Mathematical Society, right? You're in the wrong place," the girl smiled faintly and pointed across the street, "Although the lectures and poster exchanges of the academic conference were held in the auditorium of Princeton University, the accommodation was not in Princeton University, but in the hotel across the street from Palmer Square. ”

Lu Zhou: "Across from Palmer Square?" Thank you. ”

The girl smiled faintly: "You're welcome, speaking of which, Lu Zhou...... That's how it works, right? I've read your paper on the law of the distribution of Mersenne primes, and it's a great proof process, so it's no wonder that even Professor Deligne can't find fault with it. ”

Lu Zhou smiled embarrassedly: "It's just a coincidence." ”

It is a shame to say that the proof of Zhou's conjecture was actually given by the system. If you can find fault with it, it's magical.

But the system is his, the process is digested by him, and the equations are all sorted out by himself, even if he is a little proud, there should be no problem, right?

Anyway, when his mathematical level rises, it will be a matter of time before he independently proves a conjecture of this level.

The girl said, "There is no need to be modest, I am looking forward to your speech on the stage, and I am ready to ask questions." Just on the same road, I'll take you there. ”

Lu Zhou smiled and said, "I'm sorry for you...... By the way, can I ask your name? ”

Brushing the blonde hair from her ear, the girl said in a relaxed tone.

"Molina Abel, I don't really like my last name, so you can call me Lady Molina, or Miss Molina."
