Oh no, the aloof school beauty has been reborn too!

When Lu Xing walked to the classroom and sat down, almost everyone had already arrived.

On their first day of classes, freshmen were still somewhat excited.

Textbooks and notebooks were laid out on the table, and many students were scrolling through their phones while the teacher was not around.

Lu Xing found a seat towards the back of the middle and put his backpack down next to him.

He had barely taken out his textbook when the teacher walked into the classroom as the class bell rang.

The other person was a man in his forties, wearing a very simple plaid shirt.

He wore glasses on the bridge of his nose, which made him look not particularly serious.

But as soon as I entered, the classroom quickly quieted down.

"Sign in first."

The teacher placed the lesson plan on the podium, turned on the multimedia system, and said in a calm tone:

"Everyone, take out your phones and scan the QR code on the screen."

The QR code quickly appeared in the center of the screen, and a rustling sound immediately filled the classroom.

Lu Xing also took out his phone to scan the QR code, and after confirming that he had successfully checked in, he placed his phone face down on the table.

The teacher waited for two minutes and glanced at the list in the background.

Only after confirming the number of attendees did I close the sign-in page and switch to the course materials.

"Today is the first lesson, and the content won't be too difficult. We'll mainly go over a few concepts together."

As he spoke, he turned around and wrote a few keywords on the blackboard.

Lu Xing listened attentively at first.

After all, it's the first day of formal classes, so we should give the teacher some respect.

Moreover, the feeling of sitting back in a university classroom is quite subtle.

The teacher spoke slowly, starting with the basic components of the system and then moving on to other fundamental concepts.

Lu Xing held the pen, occasionally drawing two lines on the book.

But as he listened, he discovered a very real problem.

The basics are really just the basics.

This content is useful for freshmen, but for him, it's more like listening to something he already knows again.

Although listening to it again can also help solidify the understanding...

But over time, coupled with the steady lecturing in the classroom, it sounded almost like some kind of hypnotic audio.

Lu Xing happened to get up exceptionally early today, and the power of being up at 8 a.m. was slowly becoming apparent.

He was initially able to prop his chin up to look at the presentation slides, but later his eyelids began to droop uncontrollably.

No...

You can't sleep, huh!

Lu Xing sat up a little straighter, trying to make himself more alert.

But the teacher's voice remained calm and unhurried:

"Programs, like data, are stored in memory in binary format..."

The words in front of Lu Xing's eyes began to appear double.

He forced himself to turn a page, the pen lingering on the paper for a few seconds before leaving only a crooked line.

Sleepiness surged up forcefully.

He kept nodding his head, almost sinking into the table.

Just as Lu Xing was about to fall asleep completely, a hand suddenly reached out from beside him and gently patted his arm.

Lu Xing groggily raised his eyes.

The boy sitting next to him lowered his voice and reminded him:

"Hey bro, the teacher's calling you."

Lu Xing was startled.

The next second, he stood up almost reflexively.

The chair bounced up and made a sound, drawing many glances from the classroom.

Lu Xing was not fully awake yet, and there was still some drowsiness in his eyes, but he had already stood up straight.

On the podium, the teacher looked at him and adjusted his glasses.

"This student..."

His tone wasn't harsh; he simply said calmly:

"Since you were listening so attentively, let me ask you a question."

Lu Xing: "..."

It’s over.

The teacher glanced at the slides, then looked at him:

"We just talked about the difference between RAM and secondary storage."

"Then tell me, why can't programs usually be executed directly on the hard drive, but instead need to be loaded into memory?"

After the teacher finished asking the question, the classroom was quiet for a few seconds.

Many people were already looking at Lu Xing with pity in their eyes.

Lu Xing blinked, his mind quickly clearing.

He gathered his thoughts briefly and began to speak:

"The main issues are access speed and addressing methods."

The teacher's eyebrows twitched slightly.

Lu Xing continued:

"Hard disks are external storage devices with large capacities, but their read and write speeds are much slower than RAM."

"If the program directly relies on the hard drive to execute..."

He added at this point:

Simply put, a hard drive is more like a place to store data for a long time, while memory is the working area for programs to run.

The classroom fell silent for a moment.

The boy who had just woken Lu Xing couldn't help but turn and glance at him.

A hint of surprise flashed in the teacher's eyes; he had only intended to teach Lu Xing a lesson.

What kind of student comes to sleep on the very first day of class?

Unexpectedly, Lu Xing not only answered correctly, but also answered completely.

Many students may know what this means, but describing it in technical terms becomes a problem.

Lu Xing answered perfectly.

The teacher paused for a moment, but did not immediately ask him to sit down.

Instead, he turned around, picked up the chalk, and wrote a simple expression on the blackboard.

Then he tapped the blackboard.

"And what about this question?"

There was a short problem about binary and two's complement written on the blackboard.

The teacher looked at Lu Xing:

"If we use eight bits of two's complement to represent negative numbers, how should we represent them here? Please explain the process."

This time, the attention in the classroom was even more noticeable.

Many people stared at the blackboard, their expressions already starting to blank.

Lu Xing glanced at it.

After thinking for a moment, he replied:

"First, write out the eight-bit binary code for 13..."

"So -13 represented by eight bits in two's complement is..."

Lu Xing stroked his chin, answering at a moderate pace and in a steady voice.

Rather, it was through this question-and-answer session that he truly solidified his foundation.

The teacher looked at him for two seconds and then suddenly laughed.

The seriousness that was originally intended to reprimand the students dissipated considerably at this moment.

"good."

As he spoke, he put the chalk back on the podium and asked:

"What...is your name?"

"Land journey".

The teacher nodded, then asked with a puzzled look:

"Do you have some basic computer knowledge?"

Lu Xing didn't hide anything.

He nodded, his tone modest:

"I know a little bit."

After receiving the answer, the teacher's smile widened.

"Okay, sit down."

After he finished speaking, he added:

"However, basic courses also have their purpose; if you understand a little bit, you should listen carefully."

Lu Xing nodded obediently:

"Okay, teacher."

The teacher then continued the lesson without scolding him for dozing off.

As Lu Xing sat down, the boy next to him immediately leaned closer and whispered:

"Brother, my name is Zhang Yang."

Lu Xing glanced at him and responded in a low voice:

"Land journey".

Zhang Yang's eyes still held a lingering sense of amazement:

"You're so awesome."

He spoke in a very low voice, but his tone was exceptionally sincere:

"You answered such a difficult question. I was stunned when I heard it."

Lu Xing straightened the textbook, his face still showing humility:

"I just happened to see it."

"That's perfect..."

Zhang Yang glanced at the blackboard, then at him, and couldn't help but sigh:

"I haven't even figured out where the problem came from yet."

I never expected to sit next to such a big shot on the first day of school. I'd better stick close to this guy.

Lu Xing smiled and didn't continue the conversation.

If you find this kind of problem difficult, then you're probably in for a lot of trouble in the future...

Lu Xing originally thought that after this experience, he should be more sober.

Unfortunately, the curse of the Sandman is clearly not so easy to break.

The teacher returned to the slides, and the pace of the class returned to normal.

At first, Lu Xing could manage to listen for a few minutes and occasionally write a couple of words in the book.

But not long after, his eyelids began to feel heavy again.

After the tension from being called out earlier dissipated, drowsiness returned, even more forcefully than before.

Lu Xing propped his forehead with the back of his hand, trying to pretend that he was reading a book seriously.

A few minutes later, he finally couldn't hold on any longer and slowly slumped onto the table.

The sounds from the classroom gradually faded away.

Lu Xing's consciousness also sank.

------

It was a very cheap rental room.

The room was small, and the walls were a bit old.

The table was a simple wooden table, with dents and scratches on the edges.

Even though the rental house was cheap and simple, it was kept very tidy.

The bed was neatly made, the floor was swept clean, and everything on the table was arranged in order.

Lu Xing sat huddled at the table, a bucket of freshly made instant noodles in front of him.

Steam rose from the mouth of the bucket, carrying the rich aroma of the seasoning packets.

Although his salary wasn't high, he didn't have any bad habits, so his life wasn't too miserable.

For example, right now.

Although he ate instant noodles, they were still "He Yi Wei" instant noodles, and he even added a corn sausage to his meal.

"When it comes to food, we can't skimp on ourselves."

Lu Xing took a fork, stirred the noodles, and then put the sausage aside.

The laptop was placed in front of the instant noodles, with an online class playing on the screen.

The teacher in the video is explaining the implementation ideas of a basic project, and the mouse moves back and forth in the code.

Lu Xing took a bite of noodles and then looked up at the screen.

Sometimes, when he sees a crucial point, he will stop eating and reach out to type two lines of notes on the keyboard.

That was almost the period when he worked the hardest.

During the day, I would learn about projects from my seniors at the company, and in the evening, when I returned to my rented apartment, I would continue to watch courses, write code, and brush up on my basics.

The only sounds in the room were the soft whirring of the laptop fan and the slight clatter of an instant noodle cup being bumped.

Just then, the cell phone on the table suddenly rang.

The ringing broke the silence in the room.

Lu Xing kept his eyes on the computer screen and reached for his phone.

His family would occasionally call to ask how he was doing, and his sister would also bother him every now and then.

"Is that Mom?"

It could also be Lu Ningning.

Lu Xing answered the phone and held it to his ear.

"Feed?"

There was a moment of silence on the other end of the phone.

The next second, it wasn't her mother's voice that came through, nor her sister's voice.

Instead, it was a familiar, cool voice.

The sound seemed to come from a great distance, yet it was so close it felt like it was right next to my ear.

"Traveling by land?"

The last syllable rose slightly, with a hint of a smile:

"Wake up! The sun's shining on your butt!"

???

Lu Xing suddenly opened his eyes, and the light in the classroom flooded his vision.

He was still lying on the desk, his face pressed against his arm, the noise of the classroom gradually filling his ears.

Lu Xing paused for two seconds before slowly raising his head.

The words on the blackboard hadn't been erased yet, and the teacher was no longer on the podium.

The classroom was mostly empty, but many students were looking in his direction.

Lu Xing then realized that Zhang Yang, who had been sitting next to him, had disappeared sometime earlier.

Instead, Shen Qingyi was sitting next to him.

The girl rested her chin on her hand, her long hair cascading down her shoulder, and looked at him with a smile.
