The classroom was filled with the noisy gossip of the students. No one noticed the small 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 inlaid with sponge cushions.
Lin Zhixia had just organized a simple grand ceremony for him. His heart surged like a roaring wave, and the waves rolled him to the top of a mountain, allowing him to stand at the closest place to the sky. He was excited and silent, and once again fell into a state of being at a loss for words.
Jiang Yubai suddenly understood why Duan Qiyan rushed out of the classroom before - sometimes, a young man may not know how to face reality.
Jiang Yubai's coat was attached to a hat. He simply stood the hat up to cover his hair and his profile. He placed the palm of his right hand on the index finger of his left hand, carefully protecting his crown.
Lin Zhixia watched his every move and wrote in the "Human Observation Diary": "Jiang Yubai is indeed my best friend. He is always willing to accept my scenario settings. Whether it is "Exploring the Universe" or today's coronation ceremony, it can arouse his attention..."
As she wrote, she asked him, "Jiang Yubai, have you ever seen a real crown?"
"Yes," Jiang Yubai thought for a moment and added, "I have seen crowns of European royal families in museums and private collections."
"What does it look like?" Lin Zhixia tilted her head to look at him.
He recalled carefully and described it: "All of them were gems, of various colors, and each gem was about this size..." He compared the size and mentioned a specific place name: "The Victoria and Albert Museum in London, England, on the second floor of the Jewelry Collection, there is a large number of crowns inlaid with red, yellow, blue, green and purple gems."
Lin Zhixia exclaimed: "I have only seen antiques in books."
She closed her notebook and continued, "Queen Victoria of England was born in 1819 and reigned for 64 years. She and her husband, Prince Albert, promoted the first World Expo, the London World Expo in 1851, which showcased the scientific and technological achievements of various countries in the 19th century. According to the contents of the Jury Report of the 1851 World Industrial Exhibition, China exhibited exquisite silk, lacquerware, porcelain, and plant wax at the first World Expo and won medals. One of the organizers of this World Expo was the first director of the museum you just mentioned."
Jiang Yubai nodded and agreed, "You remember it very clearly."
Lin Zhixia revealed: "I want to visit museums all over the world."
"I have a Tibetan museum at home," Jiang Yubai said generously, "You can come to my house again when you have time."
Lin Zhixia immediately agreed: "Okay!"
After she finished speaking, she asked hesitantly, "Jiang Yubai, is your private collection at home like a museum?"
When Lin Zhixia was making a crown for Jiang Yubai, she cut a piece of white paper. Jiang Yubai picked up the remaining part of the paper. He used a ruler to draw a rectangle on the paper and wrote a line of words in the center of the rectangle: Lin Zhixia's museum pass. Issued on January 7, 2006. Issued by Jiang Yubai.
He handed this "pass ticket" to Lin Zhixia.
"Thank you, Jiang Yubai," Lin Zhixia clenched the edge of the ticket with both hands, "Now that I have this, can I officially visit your private collection?"
Jiang Yubai admitted: "Yes."
In fact, what he was thinking was that maybe in the future they could visit museums around the world together. It was not until this moment that Jiang Yubai put down the hat on his head and appeared in front of his classmates calmly and calmly.
At the front of the classroom, Teacher Zhai came back with a stack of test papers. He locked the test papers in the drawer of his desk and said to the students, "You have to take the test every day. You must listen carefully in class and don't be distracted. I hope everyone can get good grades!"
The podium was about one meter wide, with a Lenovo computer on it. Teacher Zhai bent down and tapped the computer keyboard, found Teacher Zhang's course PPT, and then invited Teacher Zhang to the podium.
Mr. Zhang is in charge of the topic of "geometry". He can mix multiple choice, fill-in-the-blank and calculation questions together, and explain the rules of the competitions in previous years from the basics to the depths. He pays attention to the classroom atmosphere and occasionally asks questions to students.
A real question from last year's competition was projected on the big screen. Teacher Zhang asked: "Think about it, how do you prove that the two line segments AF and EC are parallel?"
Jin Baihui from Class 18 immediately raised her hand.
Teacher Zhang called her name, and she stood up and answered: "Ceva's theorem and its converse."
"That's right!" Teacher Zhang said, "This problem looks difficult, but in fact, it is very simple. It is enough to use the Ceva theorem we just talked about. I will draw the auxiliary lines and you will understand it."
Teacher Zhang was diligently drawing the auxiliary lines, while Lin Zhixia was also reading the book "Geometric Topology" that she brought with her. She began to think about the value of the Gaussian curvature constant when the Riflow converges. She had read the relationship between entropy and Euler characteristic in the paper of Russian mathematician Perelman. As early as 2003, Perelman proved the Pomchartrain conjecture, but Perelman did not directly use the Riflow of three-dimensional manifolds...
Lin Zhixia was immersed in the world of differential geometry. Wan Chunlei caught a glimpse of the book in Lin Zhixia's hand, gasped, and asked her, "What are you reading?"
Lin Zhixia turned back to the title page: "Geometric Topology."
Teacher Zhang was explaining the solution of triangles on the podium, while Lin Zhixia was studying "Geometric Topology" in her seat. The contrast between them was very strong, and Wan Chunlei felt a huge shock. The differential equations in Lin Zhixia's book were densely packed, and Wan Chunlei didn't dare to turn her head to look in Lin Zhixia's direction.
Wan Chunlei couldn't help but test Lin Zhixia: "Your book is full of algebraic expressions, Lin Zhixia, do you think while you read it?"
Lin Zhixia said to herself, "I'm thinking back to the proof of Perelman's three-dimensional manifold Pomcaré conjecture. There's one thing I don't understand. I'm going to call the doctoral student in the mathematics department after I get home at noon today."
"Did Professor Shen give you the phone number of the PhD student in the Department of Mathematics?" Jiang Yubai paused as he was taking notes.
"Professor Shen is out on an overseas expedition and hasn't come back yet. Sister Zhu Chan helped me several times," Lin Zhixia said honestly. "Zhu Chan gave me the phone numbers of the PhD sisters in the Department of Mathematics, the Department of Physics, and the Department of Computer Science."
Jiang Yubai casually asked her, "What does Zhu Chan usually talk to you about? Ocean physics?"
Lin Zhixia recalled her conversation with Zhu Chan, with a bewildered expression on her face: "Sister Zhu Chan often asked me what my mother ate when she was pregnant with me and how many hours she slept every day. I was so confused. Adults' behavior generally has specific orientations, what is her motivation?"
Jiang Yubai was also confused.
Lin Zhixia guessed: "She wouldn't want someone similar to me..."
"A kid similar to you." Jiang Yubai helped her complete the sentence.
Lin Zhixia held up the book to cover her face: "Sister Zhu Chan doesn't know, I'm afraid of the dark, ghosts and injections."
Shen Fuxuan, who was sitting in the row in front of her, turned around and asked her, "Are you afraid of the exam, Lin Zhixia?"
Before Lin Zhixia could say anything, Jiang Yubai said decisively: "For her, the exam is just a game."
All the little movements of the students in the lecture hall could not escape the teacher's eyes. On the six-foot podium, Teacher Zhang gently reminded: "Students, listen carefully in class, keep quiet, and don't whisper under the teacher's nose. We, the students in Class 17, should pay more attention to our quality."
Lin Zhixia and all the students around her kept their mouths shut. They remained silent and successfully spent the morning training.
During the training period, teachers taught quickly and assigned a lot of homework. Students were under great pressure to compete and had a heavy academic burden. The lunch break was only two hours a day, and many students did not have time to go home. They could only go to the cafeteria of the Provincial No. 1 Middle School to have lunch, and then lie on the table in the classroom to rest for a while.
Lin Zhixia's home was very close to the school. She took the bus home, ate lunch made by her mother, and slept soundly on her bed. After waking up, she rushed to the Provincial No. 1 Middle School in high spirits to attend the afternoon training.
At 1:40 in the afternoon, Lin Zhixia stepped into the classroom. The teachers had not yet appeared, and there was a lot of noise everywhere. A circle of students gathered around the podium. Duan Qiyan stood on the podium with a red face and a thick neck, shouting, "I didn't do this!"
A classmate from Class 18 said: "Jin Baihui saw you in the classroom..."
Duan Qiyan scolded, "You believe everything Jin Baihui says. Who is Jin Baihui to you? Change your name to Jin and become her lackey. The lock of the drawer of the podium was pried open, and the test papers were read. How could I do such a stupid thing? When did I not rank first in the exams of the Normal School Attached Primary School? Do I need to peek at the test papers?"
Duan Qiyan's few words made Lin Zhixia understand what had happened.
This morning, Teacher Zhai put a stack of test papers in the drawer of the podium and locked it. Teacher Zhai adheres to the principle of "knowledge learned on the same day, digested on the same day". He holds a 90-minute test every evening and announces the test results the next morning - this is terrible news for most students.
So, this afternoon, a daring student pried open the iron lock of the drawer and stole the test papers.
After Jin Baihui's accusation, Duan Qiyan became the object of suspicion.
Lin Zhixia ran to the side of the podium and spoke for Duan Qiyan: "I am Lin Zhixia, the monitor of Class 17. Duan Qiyan is my classmate. I have known him for a semester. I don't believe he would do such a thing as picking the lock and stealing the test paper. If the lock is broken, the teacher may cancel the exam. We in Class 17 are never afraid of exams, and there is no need to pick the lock."
Several students from Class 17 gathered together and stood behind Lin Zhixia. Those who confronted her included the monitor of Class 18 and three boys from other schools.
The monitor of Class 18 said, "Jin Baihui from our class just said that she saw Duan Qiyan squatting here stealthily..." The monitor drew a circle on the ground with his toes: "Duan Qiyan took advantage of no one watching at noon to squat here and pry the lock."
Jin Baihui, who was doing her homework, was involved in this complicated dispute. Jin Baihui's seat was in the first row of the lecture hall, and she could not help but hear the conversation on the podium. Holding a signature pen in her right hand and a workbook in her left hand, she quickly walked to the monitor of Class 18 and sternly accused him, "It's 12:30 in the afternoon, and everyone in the classroom is sleeping. Duan Qiyan is hiding behind the podium. What is he doing?"
"I brought a USB drive," Duan Qiyan hastily explained, "I wanted to copy Teacher Zhang's PPT back home. I have a computer at home. Look carefully, the computer is under the cabinet. I had to squat to plug in the USB drive. There are a row of interfaces on the computer, and I couldn't tell which one was the USB interface. It took me a long time to find it!"
Jin Baihui didn't believe what he said. She raised her arm and pointed the tip of her signature pen at Duan Qiyan: "Last January, right after you finished your exam, you deliberately picked a fight with Lin Zhixia in the corridor..."
Lin Zhixia interrupted, "But, what happened last year doesn't seem to have anything to do with what happened today."
Jin Baihui said, "Duan Qiyan is not a down-to-earth person. When the teacher comes, I will sue him."
Jin Baihui stepped on the edge of the podium. She believed that Duan Qiyan was the mastermind. There was no video surveillance installed in the lecture hall, and the testimony of the witnesses would become crucial evidence.
What's more, Jin Baihui often gets good grades, ranking second in her grade. Generally speaking, teachers believe the testimonies of good students more.
Although the classroom was equipped with radiators, Duan Qiyan felt cold from head to toe. The snow in the last month of winter blew through the window and into his heart, making him feel angry and depressed. He was a little dazed.
Duan Qiyan raised his leg and kicked the desk: "Jin Baihui, what qualifications do you have to wrongly accuse me? Everyone knows that I am the most down-to-earth person. I will definitely do what I promised to others. I will sue the teacher and say that you threw dirty water on me."
Jin Baihui's eyebrows were twisted into a "川" shape. She stepped onto the podium and looked up at Duan Qiyan: "You didn't steal the test paper, so who stole it?"
"Anyway, it's impossible that he is a classmate from Class 17." Lin Zhixia said bluntly.
Her elementary school classmate Zhou Bufeng likes to steal things. Based on her observation of Zhou Bufeng's daily habits, she believes that there is no one like Zhou Bufeng in Class 17.
Behind Lin Zhixia, the students of Class 17 responded one after another: "It's not us! We in Class 17 will never pick the lock."
More and more students came to the classroom. Jiang Yubai and Shen Fuxuan also came. When they saw Lin Zhixia was surrounded by a group of people, they immediately rushed to the podium. Jiang Yubai squeezed into the noisy crowd and asked about the cause of the incident. He gently pulled Lin Zhixia's sleeve and wanted 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. I cannot escape in the face of danger. I have to find the real thief and bring justice to Duan Qiyan. This is the duty of a monitor."
Jiang Yubai reminded her: "Squad Leader Lin, there is no surveillance in the classroom. You can only use your IQ of 174 to figure out a solution."
"What can we do? If I can help you, just tell me," Shen Chongxuan looked at Duan Qiyan with pity, "Duan Qiyan was so frightened by Jin Baihui that his face turned pale."
