Thanks to the picky crow, lin11210, and dare91 for sharing my life-long thoughts, and thanks to Zhuo Shi for his review vote.

The long-distance flight was very tiring. The middle-aged woman and the reporter quickly fell asleep. Lu Qiujian still held the book "The Scattering Theory of Automorphic Functions" and read it with gusto; when the reporter woke up again after a long sleep

While talking, Lu Qiujian still kept the posture of holding the book in his hand, as if he had never rested.

The rest of the journey was a bit dull. The middle-aged woman stopped talking after the blow. Yangyang tried to strike up a conversation with Lu Qiujian several times but was blocked by her mother. The other people's topic also changed to Yao Ming's performance in the new season.

, shopping on Fifth Avenue, etc. After more than ten hours of flight, the flight landed at New York's John F. Kennedy International Airport, and everyone got up to pack their luggage and prepare to leave.

While her mother was taking her luggage, Yangyang quietly thrust a small piece of paper into Lu Qiujian's hand and whispered, "I visited your school that day and you can be my tour guide, right? It has my phone number and email address on it.

, remember to send me an email!”

Lu Qiujian was stunned for a moment, then nodded slightly, and the little girl immediately broke into a bright smile. After completing the formalities, he came out of the airport and changed several modes of transportation. After more than an hour's drive, Lu Qiujian arrived in New York and Philadelphia.

Princeton, New Jersey

Located on the Delaware Plain, bordered by Lake Carnegie to the east and the Delaware River to the west, the scenery is elegant, surrounded by green trees, green grass, and clear river water flowing quietly around the small town; at first glance, it may not seem like anything

One would think that this small town of only 30,000 people would hide a world-renowned top university.

Lu Qiujian strolled into the campus. Gothic buildings could be seen everywhere on both sides of the road. Ivy covered the entire exterior wall and the carved inscriptions all revealed a sense of history. Just as these buildings reflect, Princeton has a long history.

It has spent more than 250 years since its founding and is one of the most important figures in American history.

The fifth oldest university in history, it is also one of the four founders of the Ivy League, the top university alliance in the United States (the other three are Harvard, Yale and Columbia), because these are the oldest and most elite universities in the United States.

The school buildings are all covered with ivy, so ivy has become synonymous with them.

Turning a corner, two stone tiger statues appeared on the side of the road. Every university in the United States has its own symbol, and the symbol of Princeton is the tiger.

This university is also one of the richest universities in the world. US-NEWS recently ranked it first. It has received nearly 10 billion US dollars so far, a steady stream of donations from alumni associations and the efforts of some investment experts. In addition to

In addition to academic research, Princeton has spent a lot of money on purchasing collections for the school art museum, including works by Monet, Andy Warhol and other famous painters. It can be said that the art collection here is not inferior to any private museum.

.

The building in front of the building with Chinese characters engraved on it - Hu Yingxiang Hall was donated by Princeton alumnus and the famous Hong Kong industrialist Hu Yingxiang. His architectural design comes from a graduate of the Princeton Department of Architecture, a master of architectural design, and the Pritzker Prize, the highest award in the architecture industry.

Awarded by Robert Venturi.

Lu Qiujian stopped in front of a red and white building, which is the Institute for Advanced Study in Princeton. In 1933, Albert Einstein, the greatest scientist of the twentieth century, served as a visiting professor at Princeton after he came to the United States.

, and carry out generalization in this building

Research on the theory of relativity. People who have worked here include Oppenheimer, the father of the atomic bomb, von Neumann, the father of computers and game theory, Gödel, who shattered the beliefs of mathematicians for two thousand years, and other scientific figures.

As well as Yau Shing-tung, Chen Shengshen and Yang Zhenning, who are familiar to Chinese people.

The long history, world-class academic environment, top academic masters, strong financial strength and lofty reputation bring about an extremely demanding admission process. Every year, nearly 30,000 people apply to Princeton, but in the end only 2,000 are lucky.

The admission rate is only about 8%, which makes Princeton one of the most difficult universities to apply to in the United States. However, it still cannot stop batches of talented young people from applying.

In the three months since he possessed his current body, Lu Qiujian devoted almost all his energy to fighting for this precious exchange student spot. Fortunately, the previous owner of this body was also a top student and was one step ahead.

His grade points qualified him to apply, and then he used his paper to impress the old professor who controlled the qualifications for quota allocation, and then he got what he wanted.

Following the instructions in the email, he found the department responsible for exchange student management and submitted a full set of supporting documents. The staff quickly completed the procedures for him, "You are assigned to Butler Residential College. You can go to the dormitory to rest today.

This is the course schedule. Starting tomorrow, you can take classes with the math department!"

"Thank you, sir!" Lu Qiujian concealed his excitement. William Timothy Gowers, Andrew Wiles and other top mathematics masters in the world are teaching at Princeton, and he can have close contact with them.

It is an opportunity that everyone in the world who is interested in developing in mathematics dreams of, and this opportunity is right in front of him.

After coming out of the office building, Lu Qiujian walked slowly toward Butler Residential College along the ivy-covered wall. A sudden headache interrupted his appreciation of the beautiful scenery of Princeton. Damn it, here we go again. It seems to be earlier than yesterday.

An hour!

Lu Qiujian endured his headache and sat down on a bench by the roadside. He gently pressed his temples with his fingers, "1A7488, what's going on? Why are my headaches becoming more and more frequent!"

"This is normal. There is always a price to pay for improving your IQ in a short period of time!", an indifferent voice echoed in his mind, "The brain of this carbon-based monkey has evolved too fast, and with your

It is normal to have frequent headaches due to overuse of the brain for a period of time in order to absorb the knowledge mastered by the original owner of this body."

"Is there any solution?" Lu Qiujian punched the mattress depressedly, "Also, when can I return to my own plane! I miss my family, my friends,

I want to meet them sooner!"

"Boring emotions of lower creatures!" 1A7488's emotionless voice sounded again, "Parasite, I have long said that you only need to provide me with enough energy according to the plan, and I will let you go back; and

, now my energy is no longer enough to support daily activities, I am going to start hibernating! As for your headache, you just need to use physical activities instead of mental activities to relax yourself!", 1A7488 finally remembered to help him before entering a long sleep.
Chapter completed!
