Genius Girlfriend

Lin Zeqiu's perception of his sister is very complicated.

Before Lin Zhixia went to elementary school, she often said to him at home that completely ignored his inner feelings.

For example, Lin Zhixia once asked him: "Brother, this book describes the quantum Hall effect. As the intensity of the magnetic field increases, how do you guess the conductance of the edge Landau level of this sample?"

Lin Zeqiu's answer is only one word: "Go away."

For another example, Lin Zhixia tried him: "Brother, the inheritance of cytoplasm is maternal inheritance, and the DNA of mitochondria comes from the mother. Brother, our parents are the same, why are you and me different? Let’s read "Cell Genetic Analysis" now!"

Lin Zeqiu's answer is only two words: "Shut up."

And, Lin Zeqiu's deepest impression—that day, parents rarely took a rest and took their brothers and sisters to the park for a walk. At that time, Lin Zhixia, who was only six years old, entangled her brother and asked endlessly: "Brother, have you studied the origin of species? Do you know that there is a period in the evolutionary history of ancient humans? Do you believe that all species came from Africa? You Do you think Darwin’s "Evolution" can explain the history of the development of ancient apes? Brother, almost all mammals have hair, but sweat glands are one of the most developed organs of a person. This determines that human endurance is stronger than other mammals. Brother ,Do you know why?"

Lin Zeqiu collapsed on the spot: "Don't bother me!"

He stepped his legs and ran away. Lin Zhixia was still chasing him behind, like a demon from hell. Lin Zeqiu ran to the ends of the world, but after all he could not escape Lin Zhixia's pursuit.

He yelled at her: "Stay away from me!"

Then, he was immediately criticized by his parents. Mom and Dad blamed him for being too temperamental and being too aggressive towards his sister. His good mood of going out to play disappeared, his interest fell to the bottom, and his outing was boring.

Mom and Dad are more partial. Especially mothers have completely two attitudes towards sons and daughters. Mother can do many things for Lin Zhixia.

For example, Lin Zhixia likes to go to the provincial library. Regardless of the business in the store, my mother takes time to take her to the library every week to find books.

Mom and Dad tried their best to train Lin Zhixia. They made a sacrifice of time and money.

In order not to delay the opening of the store, my mother usually goes to the wholesale market to buy goods at four in the morning. Dad will help count the goods, collect the accounts and check the accounts. Their housework, including washing dishes, sweeping, mopping the floor, and washing clothes, is often assigned to Lin Zeqiu.

But Lin Zhixia didn't have to do anything.

Lin Zeqiu complained and his mother would tell him: My sister is three years younger than you, so can't you let her be a little bit?

He can only pretend not to care. It's a long time, and I'm used to it.

The scariest thing is that after Lin Zeqiu turned 10 years old, Lin Zhixia was keen on tutoring him in his studies.

While counseling, she asked him confusedly: "Brother, did this question stump you? Brother, do you really understand?"

In Lin Zeqiu's nightmare, Lin Zhixia occasionally asked arrogant and arrogant questions.

However, tonight, the situation is somewhat different. Lin Zhixia didn't say anything else to Lin Zeqiu besides explaining the problem-solving method.

She sat quietly on the chair, calmly watching Lin Zeqiu write. Her cheeks were white and she had morning stars in her eyes. She is a kind-hearted and beautiful little angel.

The additional questions on the math test paper have been perfectly solved by Lin Zeqiu.

Tomorrow morning, when the head teacher corrects the test paper in the class, Lin Zeqiu is likely to be the only person in the class who can write this question.

There is no doubt that Lin Zeqiu preserved the dignity of the math class representatives. He looked sideways at his sister. Although he didn't say it clearly, he was actually a little moved in his heart.

Lin Zhixia looked back at him.

Lin Zeqiu clenched the test paper tightly and said to his sister: "You are usually annoying. But when you are not annoying, you have two brushes."

Lin Zhixia nodded and told him frankly: "Brother, if you encounter a problem you don't understand, don't hold on yourself. If you can't figure it out, you should go to me. Whether it is a junior or senior high school topic, ordinary difficulty or competition difficulty, I can usually solve it. My deskmate gave me several exercise books for physics competitions, and I discovered the pattern of questioning over the years. Brother, as long as you want to know, I will tell you all of my thinking! I can Treat you as my student..."

"Okay," Lin Zeqiu closed the test paper, trying to maintain a gentle tone, "You get out, the farther you go, the better, Lin Zhixia."

"You are fierce to me!" Lin Zhixia said angrily, "I'll leave immediately!"

Lin Zeqiu chuckled: "Walk slowly and don't give it away!"

Lin Zhixia ran out of his room.

He took a deep breath and worked hard to get the English homework and Chinese homework.

Lin Zeqiu tidyed up his schoolbag, cleared the table, went to the bathroom to brush his teeth and wash his face, and finally fell on the bed exhausted physically and mentally.

Never dream of Lin Zhixia—this is his only wish before going to sleep tonight.

The next morning, Lin Zeqiu went to school as usual.

As he wished, the first class was math.

As a conscientious mathematics class representative, Lin Zeqiu has already collected the entire class's homework. Afterwards, under the sign of the class teacher, Lin Zeqiu distributed the papers to the group leader of each group.

Every student in the class has an examination paper from another student.

"Classmates," the head teacher knocked on the blackboard, "work with me to correct the test papers and help your classmates change their grades. You must write the correct problem-solving ideas in your notebook. Don't let me talk in vain. Next time When you encounter the same problem, you can't make mistakes and make mistakes, okay?"

The class teacher started with the first multiple-choice question.

Lin Zeqiu held a red pen in his hand and couldn't help but look forward to the additional questions.

He glanced at his watch from time to time.

He waited thirty-nine minutes.

A class is forty-five minutes, and get out of class is about to end in six minutes.

At this time, the entire test paper has been solved, leaving only the last additional question.

The head teacher coughed and asked the whole class: "This question is a bit difficult. It belongs to the junior high school math competition category. Has any classmate in our class wrote it out?"

Lin Zeqiu raised his hand without delay for a second.

The head teacher's eyes lit up: "Okay! Lin Zeqiu! My math class representative! Come to the blackboard and tell everyone."

Lin Zeqiu stood up in the much-anticipated glory.

He didn't even notice that "come on the blackboard" is a sick sentence.

What if you noticed it? The head teacher is a math teacher. Students should not criticize his language proficiency.

Lin Zeqiu stepped onto the stage and held up a chalk to give everyone a general idea of ​​the question.

Many classmates in the class made a suddenly realized "Oh-wai" sound.

The head teacher also praised Lin Zeqiu's method.

The head teacher said: "Lin Zeqiu used mathematical induction flexibly. When n is greater than or equal to 2, the formula listed by Lin Zeqiu is very concise and has a little trick. You should learn more from him."

This technique is not Lin Zeqiu's technique.

But Lin Zhixia's skills.

At this moment, Lin Zeqiu suddenly thought of his sister.

A terrifying assumption popped up in his mind-if his sister suddenly skipped a grade and started junior high school next year, would she crush all the junior high school students in the entire grade?

Once this hypothesis comes true, Lin Zeqiu walks in the school, will be pointed out.

Students may say: look at it! That is Lin Zhixia's brother! Lin Zhixia usually tutors her brother to do homework!

Lin Zeqiu shivered, a layer of cold sweat oozing from his back.

He had to divert his attention and force himself to think about other issues... For example, my sister has to pay 72 yuan for the hepatitis B vaccine today. Did she pay smoothly? Is she still afraid of injections?

Lin Zeqiu's worry is not superfluous.

In fact, Lin Zhixia sits on pins and needles in school.

After the bell rang for the first class, Tang Leqin, the deputy monitor of the fourth grade (1) class, walked up to Lin Zhixia and asked her: "Lin Zhixia, are you getting hepatitis B vaccine?"

Lin Zhixia silently took out a handkerchief. She untied the slipknot on the handkerchief, and lay on the table intact change worth 72 yuan.

Tang Leqin received the money, wrote down Lin Zhixia's name, and asked, "Lin Zhixia, your complexion is not so good?"

Jiang Yubai heard Tang Leqin's words and turned his head to observe Lin Zhixia. He asked: "Lin Zhixia, are you feeling unwell?"

"No," Lin Zhixia replied, "I...very well."

She is digging deep into her thinking.

Why should you be afraid of injections?

Everything must have a cause, and there must be an effect.

Lin Zhixia believes that her fear of the hospital stems from an uncertainty that cannot be controlled.

When she goes to the hospital, she can always see elderly people in wheelchairs, patients with mobile slings, and doctors who look hurried and walk fast. The hospital is the intersection of life and death, the center of contrast between health and disease, and reminds her of many philosophical issues that cannot be explained.

Liezi once said: "Ten years are also dead, and a hundred years are also dead. Let fun be a life, Xi Jiao after death." The meaning of this sentence is-don't think too much, live well.

The German philosopher Heidegger also proposed a philosophical idea called "Dasein".

The word "Dasein" means "existence" in German. Heidegger's theory can be summarized as "Beingtowarddeath", the Chinese translation of this sentence is "toward death and life".

Live to death!

According to Heidegger’s theory, although everyone is a living being, they can only be aware of their own existence and realize that one day they will die, and they will continue to grow and expand their horizons in the process of death. It is the real "Dasein".

The truth is this truth, and Lin Zhixia worked hard to comprehend Zen.

When she has an epiphany, she can overcome her fear!

Conquer yourself!

Become the "Superman" Nietzsche calls!

Become what Heidegger calls "Dasein"!

That's right, that's it.

Lin Zhixia adjusted his mentality, and then reopened the notebook to record today's "Human Observation Diary."

She wrote: Today I want to observe myself. The topic of my inquiry is-Is Lin Zhixia a weak-willed person?

This line of words written by Lin Zhixia was all seen by Jiang Yubai.

Jiang Yubai asked her: "Weak-willed? What are you afraid of?"

Lin Zhixia hesitated for a while. She didn't want to tell the truth, because she hasn't lifted the burden of idols brought to her by the "Exploring the Universe" series of comics. However, it is clear that Jiang Yubai is caring about her. She should respond honestly to a concern from a good friend.

She said softly, "I'm afraid of injections."

Jiang Yubai asked back: "Why?"

His tone was particularly concerned, and Lin Zhixia couldn't help telling him the truth: "Because the injection is very painful. I am afraid of pain. Are you going to laugh at me?"

Jiang Yubai turned around, faced her, and said to her seriously: "It doesn't matter, everyone has something to fear."

Lin Zhixia also faced him and asked him: "Jiang Yubai, what are you afraid of?"

"I'm afraid of dirty things," Jiang Yubai said of his shortcomings. "My room must not have obvious dust. The bed sheets, duvet covers, and pillow cases must be changed every day."

Lin Zhixia nodded: "You are very particular."

Jiang Yubai shook his head: "It's not too particular, I'm nitpicking."

Lin Zhixia praised him: "You are so humble."

Jiang Yubai said casually: "Not as good as you."

Lin Zhixia pulled his sleeve: "Do you think you are inferior to me?"

The friendly relationship of "mutual flattery" she and Jiang Yubai had established was shattered at this moment.

Jiang Yubai sat upright again and smoothed his cuffs, his pride seemed to be aching. But he still patiently comforted her: "Don't be afraid, the vaccine will not affect your life."

"But do you know?" Lin Zhixia said, "The essence of the hepatitis B vaccine is an inactivated virus. After the vaccine, I may have a fever."

Jiang Yubai didn't care: "You may have a fever, but you may not have a fever."

Lin Zhixia settled down and explained: "The famous mathematical reasoning—Murphy's Law tells us that if a thing develops in the direction of deterioration, it will go bad someday. When you choose any set Do integration to calculate the measurement..."

"Please speak human words." Jiang Yubai made his request.

Lin Zhixia Congshan Ruliu: "I mean, what you are afraid of will come."

"No," Jiang Yubai categorically comforted her, "You are more optimistic."

Lin Zhixia said: "I have always been optimistic."

Lin Zhixia maintained an optimistic attitude and spent several weeks steadily.

In early December, the Experimental Primary School organized a preliminary examination.

Ordinary students generally read textbooks, review hard, and browse notes before the exam.

Lin Zhixia has a certain degree of similarity with ordinary students-she also reads a lot of books before taking the exam.

But she doesn't read teaching materials.

For example, before the first semester of the fourth grade test, Lin Zhixia quickly read "Unified Theory and Superpower Symmetry", "Quantum Computing New Edition" and "Beyond Time and Space" in the library.

When she was in the examination room and quickly finished writing the test papers, she recalled the contents of those library books in her mind.

She sorted out the thoughts in her mind and repeatedly deduced mathematical equations, which was equivalent to arranging another exam for herself.

At this moment, the entire examination room was unusually quiet. The invigilator sits on the edge of the podium and never disturbs the students.

Lin Zhixia glanced at her and saw Jiang Yubai sitting diagonally in front of her.

Jiang Yubai's sitting posture is good. He holds a standard pen and writes seriously.

Lin Zhixia stared at him in a daze. Before she knew it, the school broadcasted the instruction "Teacher collects papers and the exam is over".

Lin Zhixia stretched.

The invigilator is a young male teacher. He walked up to Lin Zhixia, put away Lin Zhixia's test paper, and glanced over the English composition on the test paper. Although he was a little surprised, he didn't say anything.

"The exam is over!" Lin Zhixia declared happily.

She jumped to Jiang Yubai's table: "Jiang Yubai, how did you do in the exam?"

Lin Zhixia wanted to know what kind of mentality Jiang Yubai had after taking a large exam. In this way, her "Human Observation Diary" will have new material.

Jiang Yubai looked like he was holding the winning ticket. He smiled faintly, and declared himself: "I did average in the exam."

When Ding Yan passed by, he heard these words, and immediately said, "Really?"

Jiang Yubai unscrewed his water glass and took a sip of Fijian mineral water. Although he did not reveal a clue in his words, he felt in his heart that this time the exam must be stable. He will definitely become the first in the class.

Although Lin Zhixia is talented, she is not necessarily familiar with the skills of exam-oriented education.

And he, Jiang Yubai, after four months of emergency training as a tutor, can dream of the problem-solving method of the "Hua Luogeng Jinbei Elementary School Mathematics Competition".

This time, the math and English test papers were very difficult, and the people who wrote the questions had a strange perspective, which was worthy of the experimental textbooks of the Provincial Experimental Primary School.

Just seven minutes after the exam began, Jiang Yubai turned his head back. He found that Lin Zhixia was in a daze.

Ten minutes before the end of the exam, Jiang Yubai looked back again. He found that Lin Zhixia was still in a daze. She didn't even change her sitting posture.

Why is she motionless?

May be thinking about physics.

It was this amazing glance that made Jiang Yubai regain his confidence.

Lin Zhixia is indeed smart. She is a genius among geniuses. But she also distracted. She is also careless and absent-minded.

At this moment, Jiang Yubai stood up from his seat. His dignity also stood up from the ground. He asked Lin Zhixia: "Do you care about the ranking?"

Lin Zhixia replied casually: "Does the test result rank? I don't care. I will always be the first in grade. The total score depends on my mood."

Obviously, Lin Zhixia is too proud.

As the saying goes, "the arrogant soldier will be defeated" is not without reason.

According to Jiang Yubai's speculation, Lin Zhixia had been distracted for a long time. She probably didn't finish the test paper. Under normal circumstances, even if she finishes writing, she should take the time to check all the questions.

No one is perfect, there is heaven outside the sky, no matter how powerful opponents are, there are times when they make mistakes.

Therefore, Jiang Yubai plucked up the courage and set up a post to Lin Zhixia: "Lin Zhixia, you used to take first place in the exam because I haven't turned it over yet."

As soon as he finished speaking, several students nearby stared at him.

Lin Zhixia stared into his eyes: "You mean, this time, you did very well in the exam. Can you surpass me and be the first in grade?"

Ding Yan grabbed Jiang Yubai's sleeve and motioned with his eyes not to talk indiscriminately, not to insult and ask for trouble.

Ding Yan has seen Lin Zhixia's intelligence different from ordinary people.

He believes that no student in the school is smarter than Lin Zhixia.

As a good friend of Jiang Yubai, Ding Yan would never watch Jiang Yubai suffer humiliation in front of Lin Zhixia.

Although Jiang Yubai regarded Lin Zhixia as a competitor, he wanted to hear Lin Zhixia compliment him in his dreams. However, everyone knows that it is impossible to happen.

Ding Yan couldn't help but persuades her heartily: "Jiang Yubai, forget it, look a little bit away."

It's really interesting.

What do you mean by "look away a little"?

Jiang Yubai has his own persistence.

He put aside Ding Yan's hand and moved forward bravely, fearlessly. Facing Lin Zhixia, he said neither humble nor arrogant: "Lin Zhixia, I can surpass you. This time, I should be the first in grade."

Lin Zhixia was stunned for a moment, and then said: "Jiang Yubai, we have been at the same table for four months, and you still don't have a very comprehensive understanding of me. Let's make a bet."

As she spoke, she walked outside the classroom.

The school bags of all the students were placed in the corridor outside the classroom by the wall.

There are shoe prints on the plastic floor. Jiang Yubai picked up his schoolbag, but did not carry it on his back. He carried the schoolbag belt in one hand, followed in the footsteps of Lin Zhixia, and asked her: "Lin Zhixia, what do you want to bet?"

Lin Zhixia will stop.

The sun is shining today, and the tiles in the teaching building are bright and reflective.

She clapped a tile and said upright: "Jiang Yubai, if you are the first grade, I call you Teacher Jiang. If I am the first grade, you call me Teacher Lin to show respect."

Jiang Yubai took a step back.

He did not immediately agree.

Jiang Yubai reflected on his words and deeds just now. He thinks his behavior is not polite. Even when dealing with a competitor, he should show due respect and carefully evaluate the competitor's proposal.

Should I agree to Lin Zhixia's gambling agreement?

Jiang Yubai did very well in this exam.

His math and English should be both full marks. There is also a perfect grasp of the language.

Jiang Yubai, who has three perfect scores, got the worst result, which is nothing more than tied with Lin Zhixia for first in grade.

He accepted Lin Zhixia's bet: "Yes."

He also said: "You lose, don't cry."

"I don't cry," Lin Zhixia said, "I'm very strong."

Jiang Yubai reminded her: "Next Monday, all students in the school will be vaccinated against hepatitis B..." His voice gradually lowered, and it sounded very gentle: "Don't be afraid."

Lin Zhixia picked up her schoolbag and ran out of the corridor.

This weekend, Lin Zhixia did not go to the library for the first time.

She made an excuse to say that she was tired and wanted to take a break. Mom and Dad both showed surprise expressions.

But my brother saw her through at a glance: "Are you still worried about getting the vaccine?"

Lin Zhixia hugged the little penguin's plush toy tightly: "I don't have one."

Lin Zeqiu said: "When you are afraid, you will hug this penguin." He tilted his head: "The penguin looks stupid and stupid."

He was wearing a sportswear, changed his sneakers, picked up the basketball from the ground, and was about to go out.

Lin Zeqiu hadn't been out for a whole month.

Speaking of bitterness, last month, the family business was very busy, Lin Zeqiu cleaned up every day, and also took his studies seriously. And today! He finally came alive! He can't wait to meet his classmates and play basketball with them happily.

Lin Zhixia even asked him: "You go to play basketball, can you bring me?"

"Lin Zhixia," Lin Zeqiu asked her, "Can you play basketball?"

Lin Zhixia said: "I won't. That's why I want to observe you."

Lin Zeqiu refused: "My classmates have never played with girls. You went to the basketball court and none of us were comfortable."

"Then you can stay at home and play with me with a rope?" Lin Zhixia immediately took out a rope.

Lin Zeqiu pushed her hand away: "Don't stand in my way, I haven't touched a basketball in a long time."

"Brother..." Lin Zhixia lowered her head, "Aren't you annoying me? I didn't have a table at school before, and I didn't dare to talk to others, so I had to go to the girls to play with the rope after class. I've always been a stand-up person. My brother is not willing to play with me on the ropes anymore."

Lin Zeqiu hesitated a lot when Lin Zeqiu heard her mention that "I don't have a table at school, nor dare to talk to others".

He stood in front of the security door, took a step, and retracted his leg, even though his classmates were still waiting for him on the basketball court.

He looked at Lin Zhixia, her head still bowed.

Lin Zeqiu's heart was aching, and he said slowly, "Forget it, let me play with you with the rope."

"Then what about your classmates?" Lin Zhixia immediately looked up.

Lin Zeqiu casually replied: "What do you care about them? I am not the first day to release their pigeons. They have long been used to it."
