On the way to Tongfu University, Liu Ying walked in front to lead the way, and at the same time was very curious about Qiu Wei.

"You're also a student at Tongfu University?"

Qiu Wei shook his head, "No, I went to the library to find some books, I heard that the books there are relatively complete and open to the public." ”

I see, Liu Ying said: "Our university's library is really good, I think you are quite young, you should still be in school, now there are fewer and fewer people like you who go to the library to read and study, I guess your grades should be very good." ”

Speaking of going to school, Qiu Wei's face darkened, if it weren't for scanning the code on the bus, he would still be working hard to review at this time and strive to get into a good university.

Unfortunately, from the moment he came into contact with QR codes, his life had changed completely.

Although Liu Ying was leading the way, she had been paying attention to the people around her, and seeing Qiu Wei's gloomy face, she had obviously touched on the sad place.

She was a little stunned, then thought of some Ken ability, and then asked cautiously, "Did you drop out of school?"

"Dropped out of school?" Qiu Wei smiled bitterly, "Sort of, if it weren't for the accident, I should be able to go to a good university." ”

"I'm sorry I said something that made you sad. ”

Liu Ying couldn't help but apologize to Qiu Wei.

Qiu Wei smiled, "It's okay, I'm not that vulnerable." ”

However, in Liu Ying's eyes, Qiu Wei was forcing a smile, and he suddenly felt bad in his heart.

It's a pity, such a handsome little guy who loves to learn, most of it is because of the situation at home, and it ruined his learning career, how sad, in the face of such a blow, but still unwilling to give up, choose to be self-taught, go to the library to study.

Liu Ying began to make up for his brain, imagining that Qiu Wei was studying alone and forgetting to sleep and eat, and he was working hard in life and study, he was alone, no one supported or understood, but he loved learning and never gave up his dreams.

Ah, it's so inspirational, so pathetic.

Thinking of this, Liu Ying was almost in tears, and couldn't help but get close to Qiu Wei's side.

Ah, that's really cool!

Soon, the two arrived at Tongfu University.

It was a hot summer day, and there weren't many people in the school.

Entering the campus, a straight avenue breaks into view, and in the middle stands a statue of the emblem of Tongfu University, and a banner is pulled below, which is the slogan of Tongfu University and the message of the dean.

On both sides of the avenue, there are two boulevards, separated by a green belt.

Lush flowers, mottled shadows, faint floral scents, and the familiar chirping sounds are the taste of summer.

Entering the university, Qiu Wei no longer knows the road, this place is more than ten times bigger than his high school, even if it is a student here, there are times when he can't find the road.

Fortunately, with Liu Ying leading the way, he saved a lot of trouble.

Following the boulevard, turning left and right, passing the stadium, passing the laboratory building, and crossing the small bridge over the river, they finally arrived at their destination, the Tongfu Library.

It's huge!

This is Qiu Wei's first impression, and the design of this library is unique, from a distance, the whole building looks like an unfolded book.

At this time, Liu Ying smiled and said, "It just so happens that I also want to borrow some books and go back to see them, let's go together." ”

"That's great, do you know where the books about QR codes are?"

"QR code?"

Liu Ying was stunned, this is a little different from the plot of her brain, shouldn't it be inspirational learning?

Seeing that Liu Ying didn't react, Qiu Wei was a little disappointed and said, "Don't you know either?"

Liu Ying said: "This kind of book belongs to the category of culture and science, you can go to the west to find it, if not, you can also ask the administrator, they are more clear." ”

Qiu Wei nodded and said, "Thank you!"

"It's a trivial matter, you're welcome!" Liu Ying hurriedly shook her hand.

After entering the library, the two were temporarily separated, and Qiu Wei looked for the place Liu Ying said.

In the west area, in addition to the neatly arranged bookshelves, there is also a study area for students, and many students sit on chairs to read books or study with notebooks.

I have to say that this library is so big that a certain type of book can fill five or six extra-long shelves more than two meters high.

Qiu Wei searched for a long time, and only half of the bookshelves of culture and science were read.

In this matter, a young man came over with a few books, it seemed that he was a student here, Qiu Wei glanced at it casually, and found something.

The young man in beige short-sleeved shirt was holding a book about QR codes in his hand, apparently knowing where such books were.

Qiu Wei immediately stepped forward, "Wait, handsome guy, I'm looking for a book about QR codes, how do I go?"

"QR code?"

The young man looked Qiu Wei up and down, and then showed a lewd smile, an expression that I understand you.

Wait, I don't understand, what's going on?

Qiu Wei was a little confused, just asking for a way, as for using this expression?

"Classmate, you're too unprofessional, and you didn't inquire clearly before you came, but fortunately you met me, if someone else shows you the wrong way, you will cry when the time comes. ”

？？？

Qiu Wei's face was full of question marks, could it be that the secret of the QR code was discovered?

Before he could ask more, the young man walked inside, "What are you still doing in a daze? Come on, I'll take you there, it's free." ”

Is this still charged? Qiu Wei became more and more confused.

Walking through the rows of bookshelves, my eyes suddenly opened up.

"Now, it's right ahead. The young man pointed to the position ahead.

Qiu Wei looked along, and through his super eyesight, he could see the books on the bookshelves in the distance clearly.

After looking around from a distance, he frowned slightly, "I didn't see it." ”

The young man was stunned, "Classmate, such a big one, don't you see it?"

"Big, no!"

"Classmate, there's no need, come here, what are you pretending to be?"

These words made Qiu Wei confused, "What are you pretending?"

The young man was speechless, "I've never seen anything more pretending than you, I'm convinced, don't you just want to see the beautiful professor in our class?"

Qiu Wei then understood what happened for a while, "What a beautiful professor, I'm here to see the QR code." ”

You!

The young man really wanted to hit the tofu headlong and die.

"I'm really here to find a QR code!" Qiu Wei emphatically affirmed.

"Alright, alright, I got it. The young man waved his hand, "It's a good student who loves learning, a great sage who is not close to women, and you walk to the end full of books about QR codes." ”

"Okay, thank you!"

With that, Qiu Wei walked straight to the innermost part of the corridor and looked for books about QR codes.

"You're really looking for a book!?"

Seeing Qiu Wei staring intently at the book, the young man knew that he had misunderstood.

There are many books about QR codes, Qiu Wei casually found a copy and looked through it, which has a detailed introduction to the birth, development, and then widespread use of QR codes.

Essentially, QR codes store information in binary geometric representations that are then scanned and extracted through various devices.

There are also many different types of QR codes, and there are many application scenarios, and the larger the QR code, the more complex it is, and the larger the amount of information storage.

Just like the QR code from level 1 to level 7, the higher the level, the more complex and powerful the QR code will be.

Gradually, Qiuwei immersed himself completely, absorbing the knowledge from the books.

He was completely addicted to it, and after a long time, a faint fragrance lingered on the tip of his nose, which was intoxicating.

I don't know when, there was a beautiful woman standing next to Qiu Wei, with long black and bright hair, delicate facial features, delicate and fair skin, a delicate necklace around her white slender neck, and a white dress, like a beautiful princess who came out of a fairy tale.

The beauty has bright eyes and bright teeth, and her shining and moving eyes look directly at Qiu Wei, the corners of her mouth are slightly upturned, and her eyes are full of appreciation.

"Doesn't it feel like QR codes are magical?"

The voice was ethereal and reassuring.

Qiu Wei turned his head to look, isn't this the beautiful professor that the young man pointed to?

He was still very respectful of the teacher, and immediately put down the book in his hand and replied politely.

"Yes, I'm new to it, and I feel that there is a magical world in it, and people can't help but explore,"

The beauty smiled: "I also think so, the QR code is a wonderful invention, changed our way of life, its structure makes it have countless possibilities, many new applications waiting for people to explore and explore, I believe that in the future world, the QR code will inevitably become the most important tool, and even change the world." ”

Qiu Wei's heart moved slightly, the beauty in front of him seemed to have a specialization in QR codes, but he was a monk halfway, and there were many things he didn't know very well, this was just an opportunity, how could he waste it in vain?

"There are a lot of things I don't understand in this book, can you help me?"

"Okay! It's rare to meet someone who is interested in QR codes, and it just so happens that I still have time, so you can ask any questions. ”

The beauty agreed without hesitation, preaching and solving doubts was one of her duties, and it was also her favorite QR code, which she gladly accepted.

Under the bookshelf, the two began to ask and answer each other, attracting the attention of many people.

The beauty is worthy of being a professor and tutor, and she can always use simple examples to solve Qiu Wei's doubts, and there are some professional terms, explain it a little, and many things that don't understand and can't be explained are easily solved.

"At this stage, there are 40 levels of QR code, the highest 40L is 177*177, the higher the level, the more complex, the larger the QR code area, which requires professional equipment to scan. ”

Just like the Alien Spirit, the higher the level, the larger the size, and the stronger the ability. At the same time, its own equipment also needs to be strengthened and upgraded in order to quickly scan the code and control the power.

Maybe the seven-level QR code is the beginning, and there are more advanced QR codes and more powerful devices later.

Beyond the seventh level, whether it is a spirit or a controller, Qiu Wei has seen it, and even driven it for a short time.

It was unimaginable power, completely not on one level, as if everything was under control, omnipotent.

Now on his body, there are two QR codes of the cage manager, he has researched, and found that the structure and content are more complex and detailed than the seventh-level QR code, and the information stored is more.

Obviously, these two QR codes are beyond level seven, and they require more advanced equipment and more psionic energy to scan the code to drive.

The characteristics of the alien spirit and the QR code are highly similar, and now it seems that the birth of the QR code is really used to deal with the alien spirit.

But for some reason, this secret has not been announced, but the QR code technology that deals with alien spirits has been applied to all corners of life, and it has been returned to the mortal dust so that everyone can use it.

It's done to protect ordinary people, to stabilize people's hearts, to maintain order in the world, or for a deeper reason.

Also, what are the spirits and where do they come from......

Qiu Wei had to suspect that there was an unknown secret hidden behind this, and someone was controlling everything, and the next big flag.

"Judging from the current level, there are unimaginably many QR codes that can be generated, even if it is a sorting number for all the stars in the entire solar system, even if each one is a fine dust, it will not be used up, enough for human use, so there is no need to worry about consuming it at all. ”

"QR codes have unimaginable plasticity, theoretically speaking, the stored information can be infinitely larger, as long as you have a device that can be recognized, a book, a movie, or even a whole world, you can scan it. I think one day, when technology is strong enough, this may happen. ”

Then, the beautiful professor explained the format composition of the two-dimensional code, positioning pattern, timing pattern, correction graphic, separator, format information, data storage, error correction code......

Studying always makes people forget the time, and before you know it, two and a half hours have passed.

Because of something, the beautiful professor could only leave first, Qiu Wei regretted that some things were still unfinished, and some places had not yet been figured out.

Fortunately, before leaving, she took a copy of "QR Code from Zero" and handed it to Qiu Wei, and told her that there were detailed knowledge points in it, take it back first, and if you don't understand it, come back next time.

At this time, a young man wearing beige short sleeves walked over and gave Qiu Wei a thumbs up.

"Awesome, classmate, it's because I've lost my eyes, and I almost deceived me with a good trick, and it's not easy to win the favor of my mentor, you're famous!"

Qiu Wei frowned, "What are you talking about?" ”

"Awesome, do things without leakage, and bow to the wind. ”

Saying that, the young man really bowed his head to Qiu Wei and clenched his fists, "Classmate, get to know me, my name is Huang Xu." ”

Qiu Wei thought for a moment, "Autumn." ”

Autumn, a strange name, but as a quality college student, Huang Xu didn't care about these details.

He approached Qiu Wei and whispered, "Do you know how many people were angry with you just now!"

"What do you have to do with me?"

Huang Xu patted his brain, he really didn't know if the person in front of him was pretending to be stupid or really stupid, he couldn't tell the difference.

"Autumn-classmate, don't you know the situation? You don't think that the people sitting here are here to read? They all come to see Tutor Zhang!"

Qiu Wei muttered, "No wonder, I said why are there still people reading books upside down......"

Huang Xu continued: "Zhang Mengxian, Tutor Zhang, not only is she beautiful and kind, but she is also the youngest professor in Tianfu Academy, such a talented and good-looking genius-level person, Shenlong sees the head and the end, and his whereabouts are erratic, I don't know how many people can't see it at a glance if they want to, and even the tutor's photo has reached a sky-high price in some private groups, even if it is a back picture, it can also have a good price." ”

"Such an exaggeration?" Qiu Wei was a little incredulous.

"In fact, it's even crazier than you think, you see the school's emblem statue, which was sent by a certain big guy to please Tutor Zhang, and the teaching building behind it is also specially built by a rich second generation for Tutor Zhang, and there are many classrooms named after Tutor Zhang, as well as a gymnasium, and a playground on the west side......"

The more Qiu Wei listened, the more shocked he became, the huge Tongfu University was put together by one person?
