In July, Shen Qi began to pack his things, and he would not stay at Yanda for more than a week.

Shen Qi's bedroom door was crowded with people, and the three roommates Zhou Yu'an, Cai Qing, and Luo Ji blocked the door in a human wall posture to maintain law and order.

Zhou Yu'an is back, and he will stay in the dormitory to stay with Shen Qi for the last week.

"Who wants Topology?" Shen Qi picked up an almost torn math textbook and asked.

"I want it!"

"Give it to me, give it to me!"

The students of the mathematics department at the door of the dormitory scrambled to raise their hands to ask for books, which was the textbook used by Shen Qi.

"Li Zhenqiang, you give me honesty! Take three steps back!" Zhou Yu'an, the captain of the security team, shouted angrily, holding a broom with a murderous look on his face.

"Squad Leader Zhou, give me a chance, give me a chance! I'll invite you to dinner in the evening!" Li Zhenqiang begged bitterly.

"Squad Leader Zhou is upright, rich and noble can't be lewd, Li Zhenqiang, you villain leave quickly!" Luo Jiyi said solemnly.

Shen Qi is about to go abroad, and the position of class leader of the Department of Mathematics is officially handed over to Zhou Yu'an.

As the squad leader of the core specialty of the Academy, Zhou Yu'an is now a person with status and status.

Moreover, Zhou Yu'an's academic performance is second only to Ou Ye, and he has a certain prestige in the mathematics department.

In fact, Zhou Yu'an's connections, prestige, and organizational skills are much higher than Ou Ye.

Because Ou Ye basically didn't have any other social activities except for dating Shen Qi.

Ou Ye didn't interact with the other boys in the class, so she occasionally exchanged a few words with Zhou Yu'an.

There is no doubt that Zhou Yu'an will be the core figure in the class in the next year or two, and there is only one girl in the mathematics department this year, and most of the things are still decided by boys.

Asking for a book can be understood, but it must be rules, Zhou Yu'an stood at the door with a broomstick, like a god of war.

"Old squad leader, I like topology the most, give me your book of "Topology"!" Li Zhenqiang saw that the newly enthroned emperor of the Department of Mathematics was not good at talking, so he directly asked Emperor Shen Qi for help.

"Li Zhenqiang is a good classmate, with a strong thirst for knowledge, "Topology" sent you. Shen Qi raised the "Topology" in his hand.

Luo Ji understood, he walked up to Shen Qi, took the "Topology" with both hands, and returned to the door to hand it to Li Zhenqiang.

Li Zhenqiang received the book with his pious hands and shouted: "Thank you, thank you for the old squad leader!"

Li Zhenqiang left the door of Shen Qi's bedroom like a treasure, and he flipped through the "Topology" that Shen Qi had read, and he was very moved and even moved.

No one is more diligent than Shen Qi, this "Topology" can't be old, it can be seen that Shen Qi has studied it many times, read it very carefully, and there are lines of small characters left by Shen Qi at the key point, which is his reading experience.

Although he couldn't understand what Shen Qi wrote, Li Zhenqiang was greatly encouraged, the reason why the king was the king was the king was that in addition to talent and hard work, Shen Qi was qualified to pretend to be B, and he sweated more than others.

"Who wants Real Variable Function?"

"Who wants 'Algebraic Curves'?"

"Who wants Partial Differential Equations?"

Shen Qi gave away the math books he had read one after another, all of which were old books.

The most valuable ones are the old books, the old books used by the king of the mathematics department.

The students of the Department of Mathematics have all gained, and everyone has a share, and the old squad leader Shen is wet with rain and dew.

After the book giveaway, Shen Qi closed the door of the bedroom and pulled out a few treasures from under the pillow.

These books are the most basic textbooks of the Department of Mathematics, "Advanced Algebra", "Mathematical Analysis", and "Analytic Geometry".

Zhou Yu'an's eyes lit up and a green light shone, he was a knowledgeable person, and he knew that these basic textbooks were real A goods.

The person who has been in contact with Shen Qi for the longest time is Zhou Yu'an, he knew Shen Qi before he was in college, and they are teammates of the Olympiad national team.

When he competed in the UK a few years ago, Shen Qi was studying these university mathematics textbooks.

Zhou Yu'an lived in a room with Shen Qi during the competition in the UK, and he recognized these books.

There are three copies of the number of points I-III, a total of two books in the upper and lower volumes of the high generation, and only one book of the solution.

These six basic mathematics textbooks have followed Shen Qi for the longest time, among which the cover of Gao Dai is gone, and the title page is yellow, as if it was stolen from an ancient tomb.

"The four of us don't see each other, just pick and choose. Shen Qi said to the three roommates.

Zhou Yu'an picked the upper and lower volumes of the Gao Dynasty, Luo Ji chose a few points I-III, and the kind-hearted Cai Qing took the solution with the least number of volumes.

They are all good brothers in the dormitory, Luo Ji couldn't help it, so he gave Cai Qing a few points III.

One person gets two copies of the Shen Clan's Secret Collection, and the three roommates are all happy.

After arranging everything, Shen Qi hugged Luo Ji, Cai Qing, and Zhou Yu'an one by one and said goodbye.

"The country of the mathematics department, please. Shen Qi said to Zhou Yu'an, very solemn.

"Take care. Even though there were a thousand words in his heart, Zhou Yu'an finally only said two words, with tears in his eyes.

The brothers are gone, and the girlfriend, of course, needs special care.

Shen Qi carried a box of paper and delivered it to Ou Ye.

The box contained all the manuscripts of Shen Qi during his time at Yan University.

Ouye wiped her tears, she knew that the day had finally come and her boyfriend was leaving.

Shen Qi took out a personal object, which was a small notebook for him to record his inspiration.

"This little book may be useful to you. Shen Qi handed the small book to Ou Ye.

Ou Ye howled and cried, his body trembled, and he hugged Shen Qi and couldn't speak.

After sending all the things that could be sent, Shen Qi went abroad in a clean state.

Shen Qi stroked Ou Ye's long hair and comforted him softly: "Don't cry, don't cry, I'm waiting for you at Princeton." During my graduate studies, if I encounter a statutory long vacation in the United States, I will return to China to see you. ”

"Over there...... Stay safe. Ou Ye choked up.

"I owe you two gifts, a free trip to Switzerland and a number theory paper. Shen Qi said apologetically, and then made a promise: "In the near future, I will definitely fulfill it." ”

"Don't take it personally. Ou Ye wiped away his tears, looked into Shen Qi's eyes, and said happily and gratefully: "Meeting you is the best gift God has given me." ”

……

Although Shen Qi invited Ou Ye to Nangang City, Ou Ye still didn't go to Shen Qi's house after all.

Shen Qi returned to Nangang alone, where he will stay at home for a while to spend time with his parents before departing from Nangang Airport for the United States on August 15.

"Where's your girlfriend? didn't bring it back?" Shen Zhishan was slightly disappointed.

"She'll also go to the U.S. to study, and we'll come back together when the time comes. Shen Qi explained.

"Is there a picture of her, what's her name?" Fan Yunxia asked.

"There are photos, her name is Ou Ye, Ou is Ou of Euler, and Ye is Ye of Fourier. Shen Qi took out his mobile phone and sent a photo of him and Ou Ye by the Weiming Lake to his parents.

"This girl is so white and tender. Shen Zhishan's first impression of Ou Ye was very good, and he was full of praise: "Delicate, Sven, good-looking nose and eyes, it is a good match for Shen Qi." ”

Her eyelids ...... Cut, right?" Fan Yunxia zoomed in on the photo and observed it carefully.

"Mom!" Shen Qi couldn't help laughing, "You're an occupational disease, right?" I assure you with my professionalism that none of the parts on Ou Ye's body are fake. ”

Time at home is always short.

On August 15, Shen Qi reluctantly said goodbye to his parents and embarked on the road of studying across the ocean.

The flight of more than a dozen hours was very hard.

Shen Qi arrived at New York's John F. Kennedy Airport.

Princeton's original name was the College of New Jersey, which passed through Elizabethtown, Newark, and finally moved to Princeton, New Jersey, and officially changed its name to Princeton University in 1896.

The city of Princeton is not far from New York City, and Shen Qi arrived in Princeton City on the same day.

Princeton is a small city, and probably the city's most famous tourist attractions are Princeton University and the Institute for Advanced Study.

Princeton University is nestled in a rural countryside with beautiful views.

Shen Qi dragged the large box to the main entrance of Princeton University, stopped, and did not continue to walk.

"It's coming, it's finally here. ”

Except for daily necessities, Shen Qi did not bring a single math-related book to the United States.

Start from scratch, new challenges.

Shen Qi loves this kind of challenge.

In fact, it is useless to bring reference books in China, and most of the textbooks and literature of the Princeton Graduate School of Mathematics are compiled by themselves, and they are distributed only after students register.

The main entrance of Princeton University is not a glittering façade and looks no different from the gates of other universities.

This door has a name, it's called Fitzlanddorf Gate.

Shen Qi stood outside the Fitzrandolph Gate and could see the Nass Building, the main building of the school.

Upstairs on Nass is engraved Princeton's motto: "Dei-sub-numine-viget." ”

The meaning of this Old Latin phrase is: "She prospers by the power of God." ”

Shen Qi, who came all the way from the East, stood outside the Fitzlanddorf Gate for ten minutes without stepping into the school gate.

The legend of Princeton, Shen Qi has long heard of it.

In front of them, Princeton students have only two opportunities to enter and exit, one to enter and the other to graduate.

If you slip out halfway, you won't be able to finish your business.

Princeton does not officially recognize this legend, but it is widely circulated throughout the United States and around the world.

Shen Qi looked back into the distance, it was the east, the direction of the motherland.

Then Shen Qi stepped into the Princeton campus, the legendary temple of mathematics, and I will come!
