"Ding-dong, 100 proficiency in Introduction to Algebra rewards five achievement points. ”

Finally here, this book is very difficult for Yang Fan now, I have brushed it many times, and I have given 5 points.

It's been a long time since there's a draw.

"system, I now have a few draws for several achievement points. ”

"The three mission reward draws have not been used, and there are 5 achievement points. Nothing left. "Recently, in order to keep up with the body, I can't count the points.

Physical attributes are long-term growth, and they are used when they are used.

"The three character draws started at the same time. ”

In the heart lake, the turntable across the heavens and the earth is activated, and the names of people are carved on the turntable, like mosquitoes and ants.

"Ding Dong, the lottery was completed, and the possessed characters 25-year-old Nick Kevin, 19-year-old Gongsun Auntie, and 45-year-old Liu Bowen were obtained. ”

As their prestige grew, the winners began to abandon their childhood, starting with their teens.

Wait, how can there be a woman.

"What's the situation with this Aunt Gongsun? It's a woman, right?"

"Masters are regardless of gender, the history is long, and female masters carry a lot of buckets. ”

This is really, the female masters who are named casually can be called a lot during the Republic of China.

Push it further, because of the low status of women, if you can leave your name in the history books, you are definitely a masterpiece of heaven and earth.

Li Qingzhao is also admired by contemporary women, and Ban Zhao continued to revise the "Book of Han" for his brother, and it is not an exaggeration to call him a female genius. Su Ruolan made a mysterious diagram, which amazed the world for thousands of years.

These are just the women in ancient studies such as poetry and poetry. Such as the Huang Dao Po, who contributed to China and overwhelmed talented women.

However, no matter how good it sounds, it is also a woman. Yang Fan doesn't want to engage in the foundation, who knows what the sequelae of female possession are.

"What kind of master is that Liu Bowen?"

"Master of metaphysics. ”

Could it be that Xue Ba should be a god stick, Yang Fan said that he couldn't accept it.

"System, is there a master lottery who drives nuclear submarines, repairs sewers, and professionally helps elementary school students with their homework?"

"Yes Any realm that transcends sentient beings is a master. ”

Yang Fan was dumbfounded, the luck of the previous lottery was really good, he didn't draw a manicure, and he was a professional monkey.

The results of the number of unions are out, and tonight, Feng Yao's training is about to start again.

When the time came, Yang Fan entered the office, and everyone came, and Feng Yao was also there.

"Teacher Feng, I've finished reading this book. Yang Fan put the introduction to algebra down on the desk, and this move focused the eyes of the four people.

The four of them had various expressions and were silent.

"I guess it's about the same, I'm ready for you. Feng Yao put this book away, took out another one from the drawer, and said, "This is a book translated by the president of Nankai University in the nineties, you have to read it carefully." ”

Feng Yao held the book with both hands and handed it over very carefully.

The eighties and nineties were an era of rigorous scholarship, and this book was very heavy. The title of the book, Linear Algebra and Its Applications, Strong, was published in the nineties.

"This book has only been published in Chinese for one edition, and there are not many surviving books. ”

Yang Fan's English has also reached the third level of high school, but if you have to read professional books, it is obvious that the accumulation is still poor.

The pages of the book are yellowed, ninety years to this point, nearly thirty years. With a slight flip, there are countless handwriting on the pen, all of which are Feng Yao's reading notes.

"Thank you, Mr. Feng. Yang Fan closed the book and thanked him in a low voice.

The four of them were envious, and they didn't ask for a copy, and the previous one hadn't been started yet, and the progress was very slow.

"Yang Fan, it's time to collect your heart and prepare for the winter camp next month. ”

Feng Yao's eyes were blazing, and if he pointed out, Yang Fan understood that he was talking about basketball, hesitated for a long time, and said, "Okay, I know." ”

Feng Yao nodded and smiled, and turned back to Cui Qiming: "You won a second prize this time, you are already in the third year of high school, Olympiad mathematics, put it down." ”

Among the five people, the first one to be eliminated turned out to be the first enlightenment. Li Jianxing is a senior in high school, and his long-term development is promising.

The girl He Qing is a sophomore in high school, and she can work hard for another year, only Cui Qiming can't continue this road.

Cui Qiming looked at Ye Haoran, then at Yang Fan, and finally said, "Thank you, Teacher Feng, for your recent advice, and thank you classmates." ”

Cui Qiming walked to Yang Fan's side: "It's still the same sentence, help me suppress the river water, nothing else." ”

"Okay, I'll try. ”

"Come on. Come on, everyone. ”

Cui Qiming left the small team and will never come back. With his annual first result in the whole school, the Olympiad is just the icing on the cake, referring to the first place in the attached high school in previous years, Aurora, Nanzhou, Zhedong and so on.

"Okay, adjust your mentality, students like Cui Qiming will be company executives in the future, and they will have a worry-free life, but you, who embark on the road of mathematics major, may be so depressed that you have nowhere to eat. Feng Yao said.

Olympiad mathematics, to put it bluntly, is also to choose a famous school, after graduating from university, either enter a large company, or enter a professional research institute, which side is better.

"Ye Haoran, the roster of the winter camp, the principal is sure to stuff you in, you have to be serious, other events ...... Whatever you want. ”

Ye Haoran didn't give up on the Olympiad, this kind of science genius was born for the competition.

Feng Yao is not optimistic, students like Ye Haoran, in the world, every subject has a chance to win a bronze medal, but there is only a chance, and the gold content is far worse than a fast gold medal.

"As for the two of you. Feng Yao pointed to the left pair of men and women, "You still need to grind the water, take your time." ”

Feng Yao took out four test papers, and he was serious.

"These four volumes, the progress is different, let's start doing it now, if you can't finish it, go home and do it, I'll explain it tomorrow night." ”

The four of them took the paper, one for each of them, Ye Haoran and Yang Fan were of the same senior level, and the other two also followed the progress.

Feng Yao walked away not long after, and the only sound of writing was quiet in the office.

At 7 o'clock, Yang Fan ran away first. Since I can do it at home, it's the same everywhere.

After arriving home, his parents were watching TV in the room, and when they heard the door opening, Yang Tian came out to take a look, nodded, closed the door without saying anything, and continued to watch TV.

Yang Fan went to the small study, did not make any more volumes, and couldn't wait to open the book "Linear Algebra and Its Applications".

Flip to Table of Contents: Chapter 1, Determinants and Their Applications. Chapter 2, Matrices and Their Operations.

"The matrix, it turned out to be the matrix. ”

Yang Fan, who has been bombarded countless times by TV and movies, felt forced to be high when he saw these two words.

In science fiction movies, if you don't have a matrix name, you can't put it in the science fiction category.

Matrix operations, the inverse of matrices, the characteristics of invertible matrices, listen, what a lofty vocabulary.

Yang Fan, who had a seizure in the second year of secondary school, immediately skipped the first chapter and started reading from the matrix.

For half an hour, I didn't finish a single section.

Parentheses are very awkward to read. The matrix is actually another arrangement of the formula:

(1+2)+3=(3+2)+1, which is also a matrix.

After watching it for a long time, I was confused, but I hooked up the addiction of science fiction movies.

"Let's relax, the player hasn't been used for months. ”

Turn on the computer, the communication software opens, and Gu Changfeng sends a message: "LOL?"

I don't have enough time, and I even call myself a game, which is really lacking in morality.

Well, see if he's a little sincere, let's play a game first.

This game wasted nearly an hour, and Yang Fan sent a message: "Bastard, professional pit man, don't ask me to play games in the future." ”

Resisting the temptation of the game, Yang Fan began to reflect, why?

Think of the Matrix, think of computer blue screen data.

Yes, data.

The computer format, the expressions are all 1 and 0, which is what I am best at and what I like the most.

So, how do you see these?

Interpret the source code of the program, and you only understand the surface operation level, and you can't understand it at all.

"There is, wireless, it's wireless. ”

The desktop is closed with a wired connection, and you can't see anything by yourself. There are two computers at home, the desktop is similar to Yang Fan's personal belongings, and the notebook is for public use.

He powers on his laptop and the system boots up. When the interface enters XP, the desktop senses an infinite signal.

Turn off the sound effects and open a video app.

"Boom. ”

The whole room, as far as he could see, was filled with green numbers, two numbers 1 and 0, completely enveloping all directions.

Yang Fan's eyes were shining, and in his pupils, 1 and 0 were issued with certain rules, like flowing water, emitting from the infinite router, gathering numbers and combining them into a green light band with the thickness of chopsticks.

"It's a wireless data world. ”

The blue water-type ribbon enters the notebook's acceptance port and disappears, and another ribbon is emitted from the port and back to the wireless router.

In Yang Fan's eyes, Yingying green, illuminating the space, 1 and 0, with a perfect arc, continue one after another.

He closed the room and waited, and in the darkness, only he could see the data streamer, shining with a little light, Ambilight.

"Pretty, so pretty. ”

Looking at the light bands, he couldn't help but stick out his fingers and cut off a light belt to go to the road. However, the data stream is not a physical body, and fingers can't manipulate it.

The bands of light go around the edges along the skin, around the fingers, and move on. The surface of the body also blocked the surge of dozens of light bands.

"How should I use it?"

Wireless data, observed by the naked eye, is unique. Without the experience of his predecessors, he was at a loss.

"Harmonica, by the way, data music. ”

The harmonica is also a certain kind of data, and the note of dox corresponds to the word 1.

When the two touched, Yang Fan stared nervously, and the music penetrated the green light without interfering with each other.

"It's over, it's useless. ”

Inside the room, there are green bands of light everywhere, and the musical characters, meaninglessly drifting, do not affect the surroundings, nor interfere with the torrent of wireless data.

"It's impossible, it's all 1 in my eyes. ”

Yang Fan still didn't believe it, and after testing it a few times, it was completely useless.

"Both are equally invisible. can represent characters, why?"

He was depressed, he couldn't operate, and what he could see was just a beautiful sight. And this beautiful scenery can only be seen by oneself, so what is the meaning.

"Let me sort it out. Sound is transmitted by vibration and has physical properties, and the signal is purely data, and the two have nothing to do with each other.

One by one, the musical characters, until they disappear, there is nothing unusual.

"Of course, music 1 is just for brief expression, and data 1 is not the same concept. It could also be a lack of some factor. ”

Yang Fan studied for a while, and felt decadent. Wireless data, unchangeable, untouchable. The data tape is there, you can see it, you can't touch it.

"If I can manipulate the flow of data, then I can set up a matrix in the void. Whether it's practice or proficiency, it's obviously impossible. ”

What else did I not think of, and what else could I use.

Yang Fan recalled, what else does the system have besides possession? physical attributes, mount system, prestige system, weapon system...... Weapon systems.

"Yes, and an enchanted fountain pen. ”

Thinking of the enchanted fountain pen, Yang Fan felt as if he had found that possibility. Enchantment, which is an incredible existence, may not be without a chance.

He shuddered and pulled the pen out of his bag, hurriedly unscrewed the lid, his fingers trembling and leaning forward.

The pen tip point in a data -0.

The enchantment is sharp, 0 pops out of the data light band, castrates to the end, and floats into the void without moving, and it is the only one alone.

"Unexpectedly, it really works. ”

Yang Fan himself was stunned. The pen sings out a zero alone, then you can operate an infinite number of 0s, an infinite number of 1s.

He concocted the same method, the void connected the dots, and a series of numbers 1-0 flew out of the streamer belt, standing still.

He quickly looked back at his notebook, the video screen flickered, faded into black, and the data was received incorrectly.

"Timing. Look at how long the separated data can last. ”

For an hour, pick out the data at random, it can exist for an hour, and its green glow will weaken in the later stage until it disappears completely.

"The room is a relatively closed space, and because a single data is close to the streamer band, there may be some kind of charging phenomenon, and if it is outside, it is absolutely impossible to retain it for such a long time. ”

"If you use physical isolation, the singled out data may exist for a longer period of time, and then find a way to recharge it......"

"It's a completely independent, surreal Void Matrix. ”
