Xu Lingbo's voice was very low, like a mosquito humming: "Selling mountain products."
In early September, when school started, Xu Lingbo once carried a bag of mountain products for Lin Zhixia. Lin Zhixia refused to accept gifts from students, so Xu Lingbo had to carry the mountain products back to the boys' dormitory and then sell them to alumni of all grades through various channels.
Cassava flour and pecans were the fastest sellers and had long been snapped up by alumni. Xu Lingbo still had a large bag of dried mushrooms in his closet that no one wanted. However, Xu Lingbo was already very satisfied. He had earned nearly 1,000 yuan.
Xu Lingbo thought that Lin Zhixia would criticize him for not focusing on his studies.
Unexpectedly, Lin Zhixia didn't care about his school business at all, and only asked: "I found your paper, have you finished reading it?"
Xu Lingbo remembered the "Graduate Student Group Meeting Slacking Technique" his roommate had taught him. He nodded repeatedly, his lips curled up: "I've finished reading it, I've finished reading it."
Lin Zhixia responded meaningfully: "Okay."
Xu Lingbo smiled at her: "Teacher Lin, I went to the laboratory and brought breakfast to my sister. She got up at five o'clock..."
The "senior sister" that Xu Lingbo mentioned was Fang Yiwen, the only doctoral student under Lin Zhixia.
Lin Zhixia is a specially appointed professor of the school and enjoys extremely high treatment. She has many titles, sufficient funding, and first-class equipment in the laboratory. She has a very clear direction for Fang Yiwen, and Fang Yiwen originally loves research. Now with such good conditions and such a supportive mentor, she has been working day and night to do experiments.
Xu Lingbo is responsible for her logistical support.
He often brings food to his senior sister.
In Xu Lingbo's opinion, the three students in their group depend on each other, but others laugh at them as the "old, weak, sick and disabled group" and their alma mater, which makes him very annoyed. He contributes to the academic career of his senior sister by "sending meals to her" and speeds up her paper output. As long as the senior sister publishes a first-author paper in the first zone of SCI, their entire group can be proud.
While thinking about all sorts of things, Xu Lingbo rushed into the college's laboratory building with a bag of breakfast.
He ran into many students and teachers.
He always had a smile on his face and would take the initiative to say hello to everyone, so he became a familiar face in the entire college. When he saw Fang Yiwen, he immediately restrained his smile and respectfully offered her a breakfast: "Senior sister, come and eat."
Fang Yiwen sat on an ergonomic chair, her left leg stretched straight, her right leg raised, her knee bent, her heels on the edge of the seat, her sitting posture casual, unrestrained, and unconventional.
She asked slowly, "How much is the breakfast? I'll transfer it to you through Alipay."
Xu Lingbo said, "Four dollars and nine cents, Senior Sister."
Fang Yiwen glanced at it and said, "Come on, stop lying to me. Pot stickers, meat buns, tea eggs, tofu pudding... these will cost 9.4 yuan, right? I'll give you 9.4 yuan."
Xu Lingbo scratched his head: "I sold mountain products and made some money."
Fang Yiwen sneered: "You make money, it has nothing to do with me. I should pay you back whatever I owe you. Can't you settle this debt?"
Xu Lingbo pressed down with both hands: "Okay, okay, sister, you continue with the experiment. I'm going back to the dormitory to catch up on my sleep. Teacher Lin is here to check on me. Please send me a text message and I'll come right over."
Fang Yiwen agreed.
Xu Lingbo cheered "Oh wow" and left the laboratory leisurely. Just a few steps out of the door, he bumped into Zhan Rui again.
Zhan Rui hesitated for a long time to say "I'm sorry", so Xu Lingbo couldn't help but tease him, "Hey, you're doing artificial intelligence research, what are you doing in this lab? Look up, this is the Quantum Frontier Laboratory."
Zhan Rui explained: "My dormitory's internet speed is slow, I want to use a cluster..."
Xu Lingbo patted his shoulder and said, "Go in, Senior Sister is inside."
Zhan Rui and Fang Yiwen have become close friends. He found that as long as he completely separated his emotions from his rationality, he could get along well with Fang Yiwen. He walked to Fang Yiwen's seat and sat down in silence. Fang Yiwen asked him, "Have you had breakfast this morning?"
He replied, "The cafeteria is too crowded, so I brought some..." He took out a box of strawberry biscuits from his schoolbag.
Zhan Rui is a person who is good at observation and summary. He noticed that Lin Zhixia was obsessed with strawberries, so he guessed that there was some connection between strawberries and high IQ. So now when he buys snacks and drinks, he usually chooses strawberry flavor.
Fang Yiwen said, "Your mouth isn't dry after eating cookies this morning? Eat mine. I haven't started eating yet."
She quickly finished a cup of soy milk, saving a plastic cup. She poured half of the tofu pudding into the cup, and pushed the remaining bowl of tofu pudding in front of Zhan Rui. She also picked up pot stickers and meat buns for him. Zhan Rui hurriedly said, "Thank you..."
Fang Yiwen put one hand in front of his eyes: "Don't talk, don't make a sound, okay, I'm thinking about the formula."
Zhan Rui nodded repeatedly.
The fellow sisters and brothers gathered together and quietly enjoyed a hearty breakfast.
Xu Lingbo stood at the door in a daze. He looked at his senior sister's fluffy and unruly hair from afar, and for some reason, a lingering sour feeling rose in his heart.
The sky was clear and the breeze was gentle. The school bell rang on time at nine in the morning.
Lin Zhixia held her head high and walked slowly into a tiered classroom.
The entire classroom was packed with people. This grand occasion greatly encouraged Lin Zhixia.
She walked up to the podium, facing the students, and heard a whisper.
A group of boys from a dormitory in the first year of college came to audit Lin Zhixia's class. They came at six in the morning to reserve seats. They sat in the center of the first row, closest to Lin Zhixia and with the clearest view. One of the boys, who had just turned seventeen, said directly, "She's so pretty, my favorite type..."
Another boy whispered in agreement: "She's prettier in person than in the photo."
Discussions like these continued.
Lin Zhixia turned on the computer on the desk and adjusted her course slides before she said, "Please be quiet. Class is about to start."
The noise in the classroom gradually subsided.
Many students cast their eyes towards her. She smiled at them, and the freshman boy in the front row turned on his cell phone, placed it in the middle of his pencil case, pointed the camera at Lin Zhixia, and secretly filmed a video.
His roommate stopped him, saying, "Stop..."
But he said very sincerely: "Nothing else, I just want to learn more about this course."
The next second, Lin Zhixia said, "Hello, students. I am Lin Zhixia. This semester, I will lead you to study "Quantum Bits and Computers". Our course schedule includes two large classes per week, one homework class, and one experimental class. Regular grades account for 30% of the total score, and exams account for 70%. I have opened the school forum section. If you encounter any problems outside of class, you can ask them publicly on the forum and I will definitely answer them."
She stood straight and spoke in a clear voice: "In class, if you have any questions, you can raise your hands and interrupt me at any time. Every Friday afternoon from 2 to 3 is my office open time. If you want to communicate with me face to face, you are welcome to come to the college office building to find me..."
Under the podium, many students were writing notes quickly.
Lin Zhixia thought about it briefly. Why did the boy in the front row start taking notes before she even started talking about the knowledge point? Perhaps this was the positive attitude of a good student. Back then, Jin Baihui also kept a notebook in her hand.
Lin Zhixia nodded.
She briefly introduced the course outline and without wasting even a minute, she went straight into teaching the first lesson. She went through the basic concepts, extended to the mathematical derivations behind the concepts, and demonstrated them live on the blackboard for the students to see.
A third-year boy suddenly raised his right hand and prepared to ask a question.
This boy has a handsome appearance and a resolute look. He is known as the "God of Interdisciplinary College". His average college score so far is as high as 98 points. In his freshman year, he read the string theory textbook written by the world-renowned theoretical physicist Joseph Polchinski. He raised his hand high and was soon discovered by Lin Zhixia.
Lin Zhixia held the chalk in her hand: "Do you have any questions?"
The boy stood up and in a few words questioned the limiting conditions of Lin Zhixia's mathematical derivation.
Lin Zhixia suddenly became excited.
She put down a new blackboard and proved her calculation formula with her hands flying. Her speech speed gradually increased, and she expanded on more and more things. She also told everyone without hesitation that this knowledge was the focus of the final exam and would also appear in the students' homework in the next few months.
A group of young people in the audience showed shocked expressions.
Before the course "Quantum Bits and Computers" officially started, the college organized an assessment, and the vice president, department head, and several professors, including Professor Shen Zhaohua from the School of Physics, attended the assessment. They jointly evaluated Lin Zhixia's teaching quality.
In fact, many professors in the school believe that Lin Zhixia is Professor Shen Zhaohua’s granddaughter.
Lin Zhixia's first paper was affiliated with Shen Zhaohua's Marine Physics Laboratory. When Lin Zhixia was a child, she often appeared in Shen Zhaohua's research group. Shen Zhaohua's favorite student... the female doctor named Zhu Chan was very kind to Lin Zhixia and always smiled.
In recent years, Shen Zhaohua has made significant research achievements. She is recognized as a world-class top scientist in the industry and is often busy and invisible. The fact that she took time out to look at the new teacher Lin Zhixia's new course assessment is enough to explain some problems.
In this way, Lin Zhixia passed the assessment smoothly.
After Lin Zhixia's first class, noisy conversations broke out in the classroom.
Lin Zhixia walked out of the classroom, went to the corridor, and called a laboratory equipment manufacturer. She still needed some customized equipment, so she could only find the manufacturer to communicate individually.
She didn't hear the discussions in the classroom.
The boy nicknamed "God of Interdisciplinary College" stood in the middle of the classroom and told everyone: "Teacher Lin is pretty good. Her class is worth listening to. Have you checked the homework? The quality of the homework is quite high."
Unexpectedly, it was these words of his that led to the gradual spread of calls for "dropping out of the course".
