Chapter 16: Lu Yu? Teacher Lu?

Hey, kids, this is a library; we have the right to read these books for free, but we also have the duty to protect them.

You must never damage the books.

I remember there are also some picture books with illustrations in here; give me the book you're holding, and I'll go exchange it for a picture book for you.

Lu Yu was lowering his head to read when suddenly a student's voice sounded from beside him.

This student's brows were tightly furrowed; although there was a smile on his face, his brows betrayed disgust.

Yes!

This student named Zhou Feng indeed felt disgust toward Lu Yu's current behavior.

Zhou Feng came from a remote countryside; he loved studying and loved books.

When he was young, he often heard his family say, "Knowledge changes destiny."

This fact has also been proven.

He, a country boy, has come to Mo Du!

This was originally something that shocked the entire village.

But... his achievements go far beyond that.

He received a scholarship from the school, so he no longer needs his family to scrape together money for his college tuition, and he can even regularly send some living expenses back home.

All of this is because of knowledge.

And knowledge comes from textbooks.

Therefore, Zhou Feng cannot tolerate any behavior that desecrates books.

The only reason he hasn't exploded yet is simply because Lu Yu is a child.

"Thank you, brother, but I just like reading this book," Lu Yu said with a smile to Zhou Feng.

Zhou Feng's expression instantly turned cold as he said, "You just like reading this book? Can you even understand it? How old are you?!"

Zhou Feng didn't mean to look down on people with dog's eyes; rather...

Lu Yu was looking at a foreign book entirely in English!

Zhou Feng didn't even dare say he could understand it; a seven-year-old kid—this is heavenly!

"Brother, I'm already seven, and I can understand it," Lu Yu said honestly.

"You!" Zhou Feng was about to explode, practically dying of anger!

"Zhou Feng! He's the principal's grandson—just now many people saw the principal strolling around campus with him. You… you had better not cause trouble."

"The school belongs to the principal; even if his grandson burned down the library, we couldn't say anything. Moreover, this little brother is merely reading quietly."

"Better to do less than more."

Beside them, Zhou Feng's classmate grabbed hold of him.

Zhou Feng's emotions calmed a little, but…

He still wasn't willing to just leave; he isn't someone who fears authority, after all… he's still a student.

"Little friend, you say you can read this book? Then can you tell me its name?" Zhou Feng asked, trying his best to suppress his anger.

Is being the principal's grandson something special?

If you can't read it, you just can't read it!

This has nothing to do with status!

Lu Yu glanced at Zhou Feng and casually said, ""A Brief History of Technological Progress.""

Zhou Feng froze.

Because the book's title is exactly "A Brief History of Technological Progress"!

It's the full English version, with no translation!

Could it be… could this seven-year-old child actually understand English?

Right!

He is the principal's grandson, so… although he's young, knowing some English doesn't seem strange, does it?

"Little friend, do you know what the book talks about?" Zhou Feng switched tactics, also trying to uncover the other's true nature!

Actually, Zhou Feng is now a bit worked up; after all… the other party is just a seven-year-old kid, so even if he really doesn't understand the book's content, what's there to be embarrassed about?

This time, Lu Yu paused a moment before saying, "The book's content is actually quite simple—just as the title says, it's an introduction to the progress of technological development."

"Like the page I'm looking at now, it's explaining the difference between decimal and binary, as well as the importance of binary for computer development."

Zhou Feng's face showed surprise.

Never mind whether this is what the book says; just this speech alone is not something a seven-year-old could utter!

"By the way, the book also mentions the birth of computer languages and briefly touches on C language."

"Although it's just a simple overview of technological progress, if you read it carefully you'll still gain a lot."

Lu Yu continued speaking.

Everyone was stunned.

Is this a professor giving a lecture?

How does it feel like we're actually in a class?

"Do you understand programming?" Zhou Feng broke the silence.

"I know a little," Lu Yu said modestly.

Zhou Feng's brows furrowed again—these days kids really dare to spout any big talk!

Do they think that just hearing a few related topics somewhere makes them industry experts?

"Tell me what you know," Zhou Feng said, his expression growing colder.

……

"C language is actually quite simple."

"Of course, all of this begins with understanding."

"If you know the meaning of each function, and the meaning of each reference symbol, then you can naturally use them to construct the program you like."

"Just like our Chinese language. Once we understand the meaning of each character, we can use each character to form a sentence, ultimately achieving the purpose of expressing what's in our hearts."

"After gaining such understanding, you can look at this piece of code again."

"We first analyze from the structure, look at the comments before and after, and then we know this is a piece of code expressing what content."

"Continuing to look down, it's like peeling an onion, bit by bit splitting."

"Inside the library, at some point it became extremely Silence, only a childish voice was sounding."

"It's not that there's no one in the library."

"On the contrary, the library is now packed with people!"

"These people are either sitting on the ground or standing at the back, all looking up at a table, each holding a notebook, their pens quickly noting something."

"Looking further ahead, one can see..."

"On a table, a child is standing!"

"That's right!"

"The one who just spoke is precisely this child, Lu Yu!"

'"Teacher, the method you mentioned is very useful, but... when the code is too long and numerous, I find myself easily confused; is there any way to prevent this phenomenon?"'

"Someone raised their hand, looking earnestly at Lu Yu on the table."

"Exactly, the person who raised their hand to ask a question, the person called Teacher Lu Yu, is Zhou Feng!"

"Why?"

"Everything started just now when Zhou Feng just asked Lu Yu a question."

"Zhou Feng asked Lu Yu what he understands."

"Then... Lu Yu began to talk about programming."

"He didn't say anything too profound, just some of the simplest C language functions."

"As he spoke, people nearby began to gather."

"And then..."

"The classmates asked him to speak a little louder."

"Lu Yu then stood onto the desk."

"And then, this is the current situation."

"Lu Yu... instantly became their teacher!"

"This is... quite miraculous!"
