I'm so tired.

My brain hurts terribly.

This is a symptom of overuse of the brain.

Is it easy for me to earn 10 credits?

No, it's not easy.

But I have to persevere, I am a person with perseverance and perseverance.

Hey, this line is so familiar, it seems to have appeared a few years ago.

Ah, I suddenly want to sing, and there is a song in this place and place that is especially suitable for singing.

Forget it, let's do the question.

Shen Qi rubbed his temples to relieve the brain pain.

At 12 o'clock in the evening, progress 5/36.

One stay in the library is an afternoon and an evening.

However, the situation is not encouraging.

Suddenly, the system prompts: "The host has been studying advanced algebra for 12 hours continuously, and the math experience value is +1." ”

Host, Shen Qi

Age, 18

Mathematics Level 7 (127/250,000)

……

Mathematics was promoted to level 7 by Shen Qi, and the rate of accumulation of experience points obtained on a daily basis became slower and slower, while the experience points required to advance to the next level increased. Relying on the daily accumulation of experience points, of course, it is not as fast as doing achievements to brush up on the points of the top students.

No matter what, Shen Qi painstakingly studied Gao Dai for 12 hours, after all, he gained something and got 1 point of mathematical experience points.

The library was brightly lit late at night, and the students studied all night, and Shen Qi was not the only one who stayed up late.

Study hard and serve the motherland.

Brush up on questions all night, for whom?

Who you are and for whom, my brothers and sisters do not shed tears. Who is the most beautiful and who is the most tired...... I'm very tired from stepping on a horse, Shen Qi can't concentrate, he is cranky, looking around, hey, there are a lot of beautiful women in Yanda, and beauties also study all night? A good-looking female student must be very popular, right? Look, if you don't study hard, you can't soak in a high-quality beauty.

"Damn, what am I thinking?" Shen Qi forced himself to calm down, there were still 31 questions to complete, and the pressure was huge.

No, I'm forced to go to Liangshan, I have to make a big move, Shen Qi sent WeChat to his roommate Zhou Yu'an, he knew that Zhou Yu'an definitely didn't sleep, and the next two days will be weekends, and there will be no classes.

"Bring my knife, I'm in the library. This was sent by Shen Qi to Zhou Yu'an> Zhou Yu'an immediately replied: "What are you doing? Don't make trouble, I'll tell you!"

Shen Qi: "Pencil sharpener, I want to sharpen a pencil." ”

Zhou Yu'an: "But your pencil sharpener is not fast, use my knife." ”

Shen Qi: "Don't talk nonsense, speed!Wait, bring my wind oil essence again, go to the 24-hour convenience store and buy a box of Red Bull." ”

Zhou Yu'an: "I always feel like you're carrying me behind my back, doing something amazing." ”

Shen Qi sent Zhou Yu'an a WeChat red envelope, covering a box of Red Bull and Zhou Yu'an's errand fee of 10 yuan.

Not long after, Zhou Yu'an came to the library with a box of red bulls, which attracted everyone's attention.

"It turns out that you studied all night!" Zhou Yu'an was shocked, but also embarrassed: "Shen Xueba is smarter than others and more diligent than others, how can we live?"

"You can go, don't interfere with other people's self-study. Shen Qi smeared some wind oil essence to his temples, opened a can of Red Bull and drank it wildly.

Zhou Yu'an was not so easily sent away, he saw a large pile of mathematical literature on Shen Qi's desktop, and knew that something must have happened.

Soon, Zhou Yu'an discovered Shen Qi's test secret paper: "What is this? This question is so difficult." ”

Shen Qi whispered: "I make a long story short, I don't have much time, I have to complete these 36 questions in 48 hours, and now 12 hours have passed, and I have only completed 5 questions." ”

Zhou Yu'an didn't understand: "For what?"

Shen Qi: "For credits, and the dignity of a man." ”

Zhou Yu'an thought about it for a while and understood: "Actually, it's to pretend to be X, right?

"Ate in the afternoon. ”

"Didn't eat dinner?"

"I didn't have time for dinner. ”

"Do you want to fight so hard......" Zhou Yu'an stopped bothering Shen Qi and left silently.

Red Bull belly, sweeping hunger.

Shen Qi returned to his state, clicked and completed 3 more questions, and then fell asleep on the table.

He was so tired that it was 2 a.m.

Shen Qi woke up at 6 o'clock in the morning, went to the bathroom to wash his face, rinse his mouth, and continue to fight.

At 7 o'clock, the countdown to the credit test is 29 hours, and the progress is 9/36.

Zhou Yu'an came to the library again, with hot buns and soy milk in his hands.

"Eat breakfast Shen Qi, people are iron rice and steel, learning is a lifelong career, not bad for these few minutes. Zhou Yu said with pain, and he was also moved, and was encouraged and motivated.

After staying up all night, Shen Qi was really hungry, he grabbed the bun and devoured it: "It's delicious...... Not...... Why are there only a few buns?

"You gave me 10 yuan last night, and you can only buy so much. Zhou Yu'an explained.

Shen Qi was speechless: "Zhou Papi, you are too picky, you are reluctant to ask me to eat a few more buns?"

"Poverty limits my purchasing power, hehe, come, drink soy milk. Zhou Yu'an took a straw to pierce the soybean milk packaging film and handed the soy milk to Shen Qi's mouth.

Not far away, two female classmates who were studying in the morning exclaimed: "Tsk, true love." ”

Burst~

Shen Qi almost squirted out a mouthful of soy milk, the soy milk poured into his mouth, and was forcibly swallowed back into his esophagus by Shen Qi: "Zhou Yu'an, you can go, I still thank you very much for sending me breakfast." ”

"The library is opened by your family, can't I come to self-study?" Zhou Yu'an took out "Mathematical Analysis II" from his schoolbag, sat next to Shen Qi and read the book, looking at Shen Qi's test secret paper from time to time, he was very interested in this secret paper.

Shen Qi automatically ignored Zhou Yu'an and continued to do his questions.

In the 10th question, you need to obtain the eigenvalue of a matrix, that is, the root of the eigenequation, which is computationally intensive.

Of course, the matrix is indispensable for high-generation testing, and Shen Qi tries to replace each element of the matrix with its conjugate complex, and then do a transpose process.

In fact, Shen Qi is very good at playing the matrix, he taught himself the Gao Dai textbook when he was a sophomore in high school, he has a lot of feelings for the Gao Dai, the road to pretending to X began in the Gao Dai, and the processing of the Hermite Matrix is not difficult for Shen Qi.

Finding the minimum polynomial is a less complicated task, i.e., the polynomial with the lowest number of matrices satisfies can be improved by the methods of Frobenius or Hensel to get the correct result.

In some general journals, you can often see similar matrix theory and polynomial algebra papers, which are not very profound, but only popular science in nature.

In fact, Shen Qi's processing method has been slightly sorted out to form a neatly formatted paper body, and he can submit papers in the process of solving question 10, and he can't get on the core Chinese or science and technology core journals of Yan University, and it is always possible to submit to general journals.

Question 10 was quickly completed, Shen Qi didn't dare to slack off, and immediately began to tackle question 11.

Question 11 gave Shen Qi a headache again, here to do a physical meaning of the quantitative product of two vectors, this is not a simple algebraic problem, but a mathematical expression of Maxwell's electromagnetism. Then we have to use Ostrogradsky's theorem to convert the volume integral to the area integral.

Sun Erxiong knew that Shen Qi was the champion of CPhO, so he came up with this question and tailored it for Shen Qi.

Shen Qi spent a lot of time on question 11 and had not yet completed the final processing.

At this time, it is noon, the countdown is 24 hours, and the progress is 10/36.

Shen Qi spent nearly 24 hours in the library and completed 10 questions.

Very anxious, Shen Qi said: "Zhou Yu'an, you sit next to me, I am completely uninspired, why don't you go to other seats?" It's best to keep a distance of more than 10 meters from me, and don't appear in my line of sight." ”

"Is this really good?" Zhou Yu'an was quite resentful.

Shen Qi folded his hands together and pleaded: "Brother, Brother Yu'an, can I beg you?" This exam paper is really important to me, I only have the last 24 hours left, half of the time has passed, and the progress of answering the question is only 27.8%! If I hand over such an answer sheet, what face will I have in Yan Dachao in the future?"

"Okay, okay, I'll go. Zhou Yu'an was hurt and left, leaving the library.

Zhou Yu'an is gone, Shen Qi is still uninspired, it seems that this is not Zhou Yu'an's fault, Shen Qi blames him.

Shen Qi walked outside the library to breathe: "Hey, this time I was embarrassed and threw it at my grandmother's house......"
