Genius Girlfriend

The classroom is full of the noisy gossip of the classmates. No one noticed the little crown on Jiang Yubai's left index finger. Jiang Yubai seemed to be attending a grand ceremony. His crown was a circle of finely cut white paper, and his throne was a row of wooden chairs with sponge cushions.

Lin Zhixia just organized a simple ceremony for him. His heart surged, like a rushing ocean wave, the waves rolled him onto the top of the mountain, making him stand at the place closest to the sky. He was excited and silent, and once again fell into a situation of poor words.

Jiang Yubai suddenly understood Duan Qiyan's behavior before rushing out of the classroom-sometimes, a young man might not know how to face reality.

Jiang Yubai's coat is attached to a hat. He simply stood up his hat, covered his hair and also covered his profile. The palm of his right hand is placed on the index finger of his left hand, protecting his crown strictly.

Lin Zhixia watched his every move, and wrote in "Human Observation Diary": "Jiang Yubai is indeed my best friend. He is always willing to accept my setting, no matter "Exploring the Universe" or today His coronation ceremony can arouse his attention..."

As she wrote, she asked him: "Jiang Yubai, have you seen a real crown?"

"I have seen it," Jiang Yubai thought for a while, and added, "I have seen European royal crowns in museums and private collections."

"What's it like?" Lin Zhixia tilted her head to look at him.

He recalled carefully and described: "All gems, various colors, each gem is almost the same size..." He compared the size and gave a specific place name: "Victoria and Albert Museum in London, England, two Lou Jewelry Collection, there are a large number of crowns inlaid with red, yellow, blue, green and purple gems."

Lin Zhixia exclaimed, "I only read antiques in books."

She closed her notebook and said, "Queen Victoria of England was born in 1819 and reigned for 64 years. She and her husband Prince Albert contributed to the first World Expo, the London World Expo in 1851, which showcases the nineteenth century. The scientific and technological achievements of various countries. According to the content of the "Wang Guo Industrial Exposition 1851 Review Report", our China took out exquisite silk, lacquerware, porcelain, and vegetable wax at the first World Expo and won medals. Among them, this World Expo An organizer is the first curator of the museum you just mentioned."

Jiang Yubai nodded and agreed: "You remember it clearly."

Lin Zhixia revealed: "I want to visit museums all over the world."

"I have a collection in my house," Jiang Yubai said generously, "you can come to my house again when you have time."

Lin Zhixia immediately agreed: "Okay!"

After speaking, she hesitantly asked, "Jiang Yubai, is your private collection in your house like a museum?"

When Lin Zhixia made a crown for Jiang Yubai, he cut a piece of white paper. Jiang Yubai picked up the remaining part of the white paper. He used a ruler to draw a rectangle on the paper, and also wrote a line in the middle of the rectangle: Lin Zhixia's museum admission ticket. Date of issue, January 7, 2006. Issuer, Jiang Yubai.

He handed this "pass ticket" to Lin Zhixia.

"Thank you, Jiang Yubai," Lin Zhixia clenched the edge of the ticket, "I have this thing, can I officially visit your private collection?"

Jiang Yubai admitted: "Yes."

In fact, what he thought in his heart was that maybe they could visit museums all over the world together in the future. Until this moment, Jiang Yubai put down the hat on his head and appeared calmly and calmly in the eyes of the students.

In the front of the classroom, Teacher Zhai returned with a stack of test papers. He locked the test papers in the desk drawer, and said to his classmates: "You have to take exams every day. You must listen carefully in class. Don't be distracted. I hope everyone can get good results!"

The lecture table was about one meter wide, and there was a Lenovo computer on the table. Teacher Zhai bent over and knocked on the computer keyboard to find out Teacher Zhang's course PPT, and then he invited Teacher Zhang to the platform.

The topic Mr. Zhang is responsible for is "Geometry Problems". He can mix selection, filling in the blanks, and calculation problems together, and explain the rules of competition over the years from the simplest to the deeper. He pays attention to the classroom atmosphere and occasionally asks students questions.

A real competition question was projected on the big screen last year. Teacher Zhang asked: "Think about it, how do you prove that the two lines of AF and EC are parallel?"

Jin Baihui of Class 18 raised her hand immediately.

Teacher Zhang clicked her name, she stood up and replied: "Ceva theorem and its converse."

"Yes!" Teacher Zhang said, "This question looks difficult, but it is practical. It can't be simpler. It is enough to use the Ceva theorem we just said. I draw the auxiliary line and you all understand it. "

Teacher Zhang diligently draws auxiliary lines, and Lin Zhixia also brought her a copy of "Geometric Topology". She began to think about the value of the Gaussian curvature constant when Ricciflow converges. She once saw the relationship between entropy and Euler's characteristic number in a paper by the Russian mathematician Perelman. As early as 2003, Perelman proved the Poincaré conjecture, but Perelman did not directly use the Ricciflow of the three-dimensional manifold...

Lin Zhixia is immersed in the world of differential geometry. Wan Chunlei caught a glimpse of the book in Lin Zhixia's hand, took a breath on the spot, and asked her, "You, what are you looking at?"

Lin Zhixia turned back to the title page: "Geometric Topology."

Teacher Zhang explained the solution of triangles on the podium, and Lin Zhixia in the seat "Geometric Topology". The contrast between the two of them was very strong, and Wan Chunlei felt a huge impact. The book of differential equations in Lin Zhixia's hand is densely packed, and Wan Chunlei does not dare to turn his head and glance in the direction of Lin Zhixia.

Wan Chunlei couldn't help but test Lin Zhixia: "Your book is all algebraic, Lin Zhixia, are you thinking while reading it?"

Lin Zhixia said to herself: "I'm thinking about the proof process of Perelman's three-manifold Poincaré conjecture. I have one thing I don't understand. After going home at noon today, I will call a PhD student in the Department of Mathematics."

"Professor Shen gave you the phone number of the PhD in the Department of Mathematics?" Jiang Yubai paused with his fingers while taking notes.

"Professor Shen went to study abroad and has not come back. Sister Zhu Chan helped me several times," Lin Zhixia said honestly, "Zhu Chan gave me the phone numbers of doctors and sisters in the Department of Mathematics, Physics, and Computer."

Jiang Yubai asked her casually: "What does Zhu Chan usually chat with you? Is ocean physics?"

Lin Zhixia recalled the content of her conversation with Zhu Chan, with a dazed expression on her face: "Sister Zhu Chan often asks me what my mother eats when she is pregnant with me and sleeps for a few hours a day. I am puzzled. Adults In general, her behavior has specific orientation. What is her motivation?"

Jiang Yubai was also puzzled.

Lin Zhixia guessed: "Won't she want someone similar to me..."

"A child similar to you." Jiang Yubai helped her add a sentence.

Lin Zhixia put up the book and blocked her face: "Sister Zhu Chan doesn't know, I'm afraid of the dark and ghosts and the injections."

Sitting in the front row of her, Shen Jixuan turned his head and asked her, "Are you afraid of the exam? Lin Zhixia?"

Before Lin Zhixia said anything, Jiang Yubai concluded: "For her, the exam is a game."

All the small movements of the students in the amphitheater cannot escape the teacher's eyes. On the six-foot podium, Teacher Zhang gently reminded: "Students, listen carefully, keep quiet, and don't whisper under the teacher's nose. Our classmates in Class 17, should pay more attention to quality."

Lin Zhixia and all the classmates near her shut up in unison. They remained silent and successfully passed the morning training.

During the intensive training period, teachers attend classes quickly and assign a lot of homework. Students are under great competitive pressure and the academic burden is very heavy. There are only two hours of break every day at noon. Many students have no time to go home, so they can only go to the canteen of the Provincial No. 1 Middle School to settle their lunch, and then lie down on the classroom table for a little rest.

Lin Zhixia's home is very close to the school. She took the bus home, ate the lunch her mother had cooked, and slept in her bed happily. After waking up, she rushed to the Provincial No. 1 Middle School in vigor to participate in the afternoon training.

At 1:40 in the afternoon, Lin Zhixia stepped into the classroom. The teachers hadn't appeared yet, and there were noisy noises everywhere. There was a circle of classmates near the podium. Duan Qiyan blushed and stood on the podium roughly, yelling: "This is not my job!"

A classmate of Class 18 said: "Jin Baihui saw you in the classroom..."

Duan Qiyan scolded: "You believe in what Jin Baihui says. Who is Jin Baihui? You change your name to Jin and be her horse. The lock of the desk drawer was broken, and the test paper was seen all over. How could I do it? Such a stupid thing? Which one of my exams was not the first in the primary school attached to the normal school? I need to peek at the test paper?"

Duan Qiyan's few words let Lin Zhixia understand what happened.

This morning, Teacher Zhai put a stack of test papers in the desk drawer and hung a lock by the way. Teacher Zhai adheres to the principle of “knowledge of the day, digestion of the day”. A 90-minute test is held every evening and the test results are published the next morning. This is a terrible news for most students. .

So, at noon today, a bold student broke the lock of the drawer and stole the exam papers.

Under Jin Baihui's identification, Duan Qiyan became the object of suspicion.

Lin Zhixia ran to the podium and spoke for Duan Qiyan: "I am Lin Zhixia, the monitor of Class 17, and Duan Qiyan is my classmate. I have known him for a semester. I don't believe that he will make a lock pick and steal the test paper. Things. If the lock is broken, the teacher may cancel the exam. Our 17th class is never afraid of exams, let alone picking the lock."

Several classmates from Class 17 gathered spontaneously and stood behind Lin Zhixia. The people who confronted her included the monitor of Class 18 and three boys from other schools.

The squad leader of the 18th class said: "Our class’s Jin Baihui just said, she saw Duan Qiyan squatting here sneakily..." The squad leader drew a circle on the ground with his toes: "Duan Qiyan took advantage of no one at noon. Squat here to pick the lock."

Jin Baihui, who was working on the question, was involved in this complicated dispute. Jin Baihui's seat was in the first row of the amphitheater, and she inevitably heard the conversation on the podium. Holding the signature pen in her right hand and the exercise book in her left hand, she walked quickly to the monitor of the eighteenth class, and sternly accused: "At 12:30 noon, everyone in the classroom is sleeping, and Duan Qiyan hides. What are you up to behind the desk?"

"I brought a USB flash drive," Duan Qiyan hurriedly defended, "I want to copy Mr. Zhang's PPT home. I have a computer at home. Please open your eyes and look carefully. The host is under the cabinet. I must squat down to insert the USB flash drive? There is a row of ports on the host, I can’t see which one is the USB port, I found it after searching for a long time!"

Jin Baihui didn't believe his words. She raised her arm and pointed to Duan Qiyan with the tip of her signature pen: "In January last year, just after you finished the exam, you deliberately found faults and quarreled with Lin Zhixia in the hallway..."

Lin Zhixia interrupted: "However, the incident last year and today's incident seem to have nothing to do with it."

Jin Baihui said, "Duan Qiyan is not a down-to-earth person. When the teacher comes, I will sue the teacher."

Jin Baihui stepped on the edge of the platform with one foot. She believes that Duan Qiyan is behind the scenes. There is no video surveillance installed in the lecture theatre, and the testimony of witnesses will become vital evidence.

What's more, Jin Baihui often gets good grades in the second grade. Generally speaking, teachers trust the testimony of good students more.

There are obviously radiators installed in the classroom, but Duan Qiyan feels cold from head to toe. The blizzard of the twelfth lunar month of winter passed through the window and floated to his heart, putting him in a space of resentment and depression, and his sanity was a little trance.

Duan Qiyan raised his leg and kicked the desk: "Jin Baihui, what qualifications do you have to wrong me? Everyone knows that I am the most practical. I promise others, I will do it 100%. I want to sue the teacher and say you splash me Dirty water."

Jin Baihui's eyebrows twisted into the word Sichuan. She stepped on the podium with both feet and looked up at Duan Qiyan: "You didn't steal the test paper. Who stole it?"

"Anyway, it can't be a classmate of our seventeenth class." Lin Zhixia said with perseverance.

Her elementary school classmate Zhou Bufeng likes to steal things. Based on her observation of Zhou Bufeng's daily life habits, she believes that there is no person similar to Zhou Bufeng in Class 17.

Behind Lin Zhixia, the students of Class 17 responded: "It's not us! Our Class 17 will not pick the lock if we are killed."

The classmates in the classroom gradually increased. Jiang Yubai and Shen Shixuan also came. They saw Lin Zhixia surrounded by a circle of people, and immediately rushed to the vicinity of the podium. Jiang Yubai squeezed into the crowd and asked about the cause of the incident. He gently pulled on the sleeve of Lin Zhixia's clothes, trying to take her to the back seat.

Lin Zhixia said to Jiang Yubai: "I am the monitor of Class 17, and Duan Qiyan is a classmate of Class 17, and I can't escape. I want to find the real thief and be fair to Duan Qiyan. This is the duty of the monitor."

Jiang Yubai reminded her: "Squad leader Lin, there is no surveillance in the classroom. You can only use your 174 IQ to find a solution."

"What way? If I can help you, just say it," Shen Jixuan's pitying eyes fell on Duan Qiyan's body, "Duan Qiyan was scared to death by Jin Baihui."
