"Elbow, Liu Rui, let's go, you two take care."

"I'll see you in two months."

Dragging the suitcase, Shi Shang and Huang Guangming waved their hands, leaving a dashing back, and Lu Zhou and Liu Rui were left in the empty bedroom.

Summer vacation has begun.

In less than a week, the entire school will be deserted, and it will not be until the end of August that people will return to school. At that time, the school will be back to the bustle, not only the returning students, but also the fresh younger students.

Lu Zhou finished writing the application for staying in school, said hello to Liu Rui, left the dormitory with his computer bag, went to the dormitory manager first, handed in the application form, and then went to the library.

There is still nothing to say about the academic style of Jinling University, although most of them have left the school, but the library is still full of graduate school entrance examination troops. Some seats are stacked with stacks of books, even if there are no people, to occupy the seats.

Sometimes Lu Zhou can't help but wonder, what are these people trying to do, some of them have a thick layer of dust on their books, and they don't see anyone come once.

Seeing that there was a book on the place where he usually sits, Lu Zhou was about to change his position, but he saw Chen Yushan, who was sitting next to him, quietly took the book away, and beckoned to himself.

Lu Zhou suddenly realized that this son was occupied for himself.

Then he was not polite, and walked straight over there.

Putting the laptop on the table, Lu Zhou didn't rush to sit down, but went to the bookshelf next to him.

Thinking back to the contents of the book list, he hesitated for a moment, and finally took "Linear Algebra (Defense Industry Press Edition)" from the shelf.

Although the system gave him a list of books that suited him, and even marked the position of each book on the shelf through a holographic image that only he could see, unfortunately, this time the system did not mark the value coefficient of each book, and he could only choose the reading order based on his own judgment.

Don't underestimate the choice of reading order, there is a certain coherence between knowledge and knowledge, and even between disciplines will affect each other.

Without learning the basic courses of "Semiconductor Physics" and "Basic Circuit Design", it is difficult to understand the knowledge points of "Microelectronics", and without the foundation of microelectronics, reading "Introduction to IC Design" directly will feel like reading a book from heaven.

Starting with mathematics is undoubtedly a conservative choice.

Normally, it is the foundation of mathematics that affects the understanding of the knowledge points of other science and engineering disciplines, and it is rare that other science and engineering disciplines in turn affect mathematics. And it just so happens that mathematics is Lu Zhou's area of expertise, and although some things are also new knowledge, at least they won't make him feel overwhelmed.

It just so happens that there are still big loopholes in his knowledge of mathematics, and many places are a hammer in the east and a stick in the west.

For example, because of the first exchange paper, he has a very in-depth understanding of some knowledge points of complex and consolidation and functional analysis, but he is completely blind to the part of knowledge points that are not covered in the paper.

It's a shame that no one is bored with the textbook to test him, otherwise there will definitely be problems in the first test.

A person who has not even finished the textbook of functional analysis talks about "the optimal inversion theory of linear operators and linear functions" in the core journal, and he is afraid that no one will believe him when he talks about it as a joke.

"If only there was water." took out the pure white medicine bottle from his pocket, Lu Zhou, who was standing behind the bookshelf, looked at the water cup on Chen Yushan's table and hesitated, and finally gave up that bold idea.

Taking out a capsule, Lu Zhou threw it into his mouth with his eyes closed, holding back his mouth and spitting and forcibly swallowing it.

After waiting for a while, just as he was strangely unchanged, suddenly, a slight tingling sensation spread from the back of his head to all sides, and finally swept his eyes towards the center of his eyebrows.

It's hard to describe the feeling, it's like an invisible ant crawling over your head.

Nanobots?

Or is it some kind of special chemical hormone?

Lu Zhou didn't know, because the black technology provided by the system was beyond the scope of the existing knowledge in this world. The only feeling is that he only feels that his brain is extremely clear and his thinking is extremely meticulous at this moment, just like Newton Einstein Heimerdinger possessed.

And this feeling is like eating Xuanmai, and I can't stop at all.

Lu Zhou realized that this was the effect of the medicine.

Without any hesitation, he took the book back to his seat and sat down, meticulously turning the first page of the book.

The effect of the focus capsule is different from the experience of immersive reading the last time I did the task.

The last immersive reading experience was more akin to a kind of wholehearted devotion, a kind of swallowing by a long whale.

The feeling that the focus capsule brought to him was more like stimulating the activity of his brain cells, allowing him to accept knowledge and attach a little bit of thinking about himself.

Minutes and seconds passed, and soon from noon to six o'clock in the evening, the sky outside the window was dark.

Chen Yushan stretched her waist and glanced in the direction of Lu Zhou, seeing that he was still in the same posture as an hour ago, she couldn't help but secretly admire him.

Talent!

It turns out that this is how Xueba is made!

But if you sit like this all the time, won't your neck be sore?

"Hey, junior, are you going to the cafeteria?" Poked Lu Zhou's arm, Chen Yushan asked in a low voice.

"You go first, I'm not hungry yet." Lu Zhou shook his head.

Five hours have passed, and the effect of the drug is slowly decreasing, but there is still a little residual feeling.

He wanted to try to see how long this feeling would last?

"Then I'll go first......" Chen Yushan suddenly remembered something, and continued in a low voice, "By the way, do you remember the part-time job I told you?" ”

Lu Zhou asked, "Remember, when will it start?" ”

Chen Yushan whispered: "Tomorrow is Saturday, why don't we make an appointment to meet in the morning?" I'll take you to meet my aunt. ”

Lu Zhou thought for a while and nodded: "Okay." ”

It just so happens that he will be fine tomorrow, and he will have to wait 24 hours if he wants to take drugs and read books again.

Gaoxin, who costs 200 yuan an hour, has paid his tuition for the next academic year after a few times.

The two agreed to meet at the school gate at nine o'clock tomorrow, and then Chen Yushan simply packed up the things on the table and got up to go to the cafeteria.

With Chen Yushan gone, Lu Zhou returned his attention to the book.

As time passed, he could clearly feel that his concentration was gradually declining, moving closer to his usual state.

What used to be a knowledge point that could be understood at a glance may now have to be read back and forth several times.

And the most obvious point is that without the restraint of the drug, his mind wandering is somewhat serious, even more serious than usual.

Glancing at the dense notes on the notebook, as well as the notebook that had been automatically turned off, Lu Zhou sighed and took out his mobile phone to look at the time.

It's already half past seven.

Until now, his stomach is too hungry to die.

"The effect lasts for five hours, and after the duration has passed, the effect will continue to decay for more than an hour until it is gone."

"You can't read books at all without drugs, this can't be done......"

After thinking about it, Lu Zhou picked up the book and went to the librarian, took out the library card to register the borrowing, and then packed up his things and left the library.

On the way back to the dormitory, he stopped by the cafeteria and ate a bowl of noodles casually, which was considered to be a solution for dinner.

After returning to the dormitory, Lu Zhou sat down in his seat and continued to read.

Regardless of the efficiency of receiving knowledge, it is a little bit to be able to see a little.

Although the acceptance of knowledge in a normal state is very slow, this does not prevent him from consolidating those knowledge points that he has already learned, and extending them to a certain extent on this basis.

Of course, the main thing is that he doesn't want to become overly dependent on this focus capsule.

After all, there are only 40 pieces of this thing in a bottle, and when it runs out, it will be gone, and at that digit burst rate, it is not necessary to wait for the next time this thing is drawn.

At about nine o'clock, Liu Rui, who had gone to participate in the training and mobilization meeting of the Mathematical Modeling Competition, returned to the dormitory with a large bag of reference books.

Seeing Lu Zhou studying, he put down his shoulder bag and immediately came over.

"Elbow, I'm done with the exams, and I'm still reading?"

"I'm idle anyway, and I haven't had much to do lately." Lu Zhou said with a smile.

Looking at the contents of the book Lu Zhou was reading, Liu Rui didn't say anything.

Once he accepted this setting, he found that his mind was much calmer.

If it was a gap of one or two points, he still had hope of catching up, but this gap between 90 points and a perfect score made him not even have the courage to catch up.

It's really uncomfortable to think about.

One month before the exam, I started to study every day with my eyes open, and I was still doing questions when my eyes were closed. As a result, he was still working part-time two weeks before the exam, so he "woke up" before the exam, moved a little twice, and then blew him and Luo Rundong away.

Liu Rui still couldn't figure out what had happened to him that the change was so amazing.

Finally, he couldn't help it and asked the confusion in his heart.

"Elbow, you learn math, do you have any tricks? Can you teach me? ”

When he said this, Liu Rui blushed a little.

After all, in the past, every time his roommate asked him questions and borrowed notes, he was quite reluctant.

Lu Zhou stopped his pen and thought seriously for a while.

"I don't know...... Probably, talent? ”

“……”

Hearing this, Liu Rui almost spurted out a mouthful of old blood.

Don't pretend to be like this, it's good to be a scumbag with dignity!

Looking at the back of Liu Rui Muran returning to his seat, Lu Zhou sighed silently, and said in his heart that most of this friendship boat has capsized again.

But what could he do?

He's desperate, too.

You can't tell people that you have a system in your head, right?
