At two o'clock in the afternoon, Yi Xiaochuan appeared in front of the library on time, carrying a small bag and a water cup, but the water in the water cup was dark red and dark red, and he gnawed on the flatbread in his mouth, gobbling it up, and swallowed it in three or two bites.

In the same position, Otogawa sat down with the book "Advanced Mathematics (Volume II)".

In front of him, there was still the little cute elementary school girl, the two glanced at each other, and the elementary school girl shyly looked away.

The library aunt happened to be sorting out the books and passing by Brother Xiaoyi, and when she saw the water cup, she smiled and said, "Classmate, it's good to drink some brown sugar water for low blood sugar......"

Brother Xiao Yi smiled.

The elementary school girl looked at it curiously, it's really true!

Can stumped boys drink brown sugar? Isn't it something that girls can drink at that time?

Hee-hee-hee!

It's funny!

Otogawa is very thick-skinned, so he naturally doesn't care about other people's eyes.

But in order to only have a little bit of "Advanced Mathematics (Volume II)" left, it seems a bit wasteful to consume a little energy.

So, he stood up again, walked around the bookshelf, and took out a copy of Mathematical Analysis, fourth edition, edited by the Department of Mathematics of East China Normal University.

This is a foundational course for college math majors.

Next, take out a copy of "Overview of Advanced Algebra Fifth Edition" and a copy of "Ordinary Differential Equations".

"Let's start with three books for the time being!"

first drank half a cup of brown sugar water to cushion the bottom, and then Yi Xiaochuan began to brush the book.

Either way, you must take your math to the next level today.

Settle in!

Knowing the hysterical hissing in the shade of the trees, the sun was venting on the ground, the elementary school girl threw down the pen, rubbed her neck, and looked up at Yi Xiaochuan, the boy who drank brown sugar water was still concentrating on flipping through the book.

It's already the third book.,The two books that have been turned over "Advanced Mathematics (Volume II)" and "Mathematical Analysis" are placed in front of the elementary school girl.。

"Are you reading a book, or are you looking for something? It's hard to just flip through it and figure it out? This isn't a novel!"

The elementary school girl pouted, turned the pen in her hand, and stumped her with another question......

I don't hear anything outside the window, and I only read math books.

Brother Yi swims in the ocean of mathematics and is unaware of the outside world.

As the sun set, the elementary school girl had already packed up her textbooks, lazily lying on the table, and was about to leave just now, going back to the dormitory to drink brown sugar water.

But I'm really curious, when will this male classmate who drank brown sugar water without even raising his head after flipping through books for an afternoon come back from the ocean of knowledge.

Looking at the "Ordinary Differential Equations" in front of him, it was also the last few pages, and the elementary school girl felt that she could wait.

Well!

It hurts!

I really want to drink hot brown sugar water.

It's best to have a handsome boy cook it for me to drink, add a few slices of old ginger, and I will definitely cry happily......

Looking at Brother Xiaoyi's half cup of brown sugar water, the elementary school girl swallowed her saliva, then picked up the cute HelloKitty pink water cup in front of her and took a small sip of hot water.

Sure enough, after turning to the last page, Otogawa stopped.

Really stopped.

At the moment of detachment, it was pitch black in front of him, and the sky was spinning.

Fortunately, Xiao Yige's spirit was tough enough to endure the painful few seconds, and after his eyes recovered, he got the water cup with trembling hands.

"Gurgling ......"

Half a cup of brown sugar under water, so comfortable!

Summoning the attribute panel, Otogawa was stunned.

"There is a sentence MMP that I don't know whether to say or not!"

[Host: Otogawa]

[Energy: 4 points]

【Opened Subject: Mathematics LV0 (99/100%)】

[Unlock ability: Code Cracking (Mathematics LV1)]

[Skill: Concentration (consumes 1 energy per hour), energy absorption]

It's like a cat scratch to be able to level up one percent of the time, how can it be just a little bit worse? Isn't it crazy?

System, you're too bad.

Big bad.

Let me come back when I'm full.

It's not that Yi Xiaochuan doesn't want to work hard to read another book, but his body doesn't allow it!

After an afternoon of meditation, a full three hours, the body has been hollowed out.

I feel that if I continue to look at it, I must pass out, and I may have to go to the hospital for the night today.

The body is the capital of the revolution, and Yi Xiaochuan will not practice his body for the sake of "code breaking".

It's still a long time coming!

There is no hurry.

But it's still angry to think about!

Standing up with a sad and indignant mood, he walked away with a glass of water in a very unhappy mood.

The elementary school girl blinked, what's wrong?

Moodiness?

No wonder you go to the library alone, no wonder you have a single dog!

Oops!

What about tomorrow's high math exam?

Waiting for Yi Xiaochuan to go around the three canteens, three more meals were eaten.

Fortunately, a large amount of rent was recorded at noon, otherwise with his current food consumption, three meals a day, plus a predictable amount of supper, how could he eat a hundred yuan a day, this is still eaten in the cafeteria!

If you eat something good, occasionally get some old chicken and red ginseng soup to make up for it, this is 8,000 yuan a month......

It really doesn't feel enough!

At seven o'clock in the evening, Yi Xiaochuan came back from a walk around the various canteens, the cup was full of brown sugar water, full of food and drink, and full of confidence.

Math LV1!

I'm coming......

Probability Theory and Mathematical Statistics, Theory of Real Variable Functions, Theory of Complex Variable Functions, Differential Geometry, Partial Differential Equations, Computational Methods, Abstract Algebra, Functional Analysis, Topology.

This is the mathematics course that Yi Xiaochuan inquired about, and since the school teaches this course, it naturally makes sense.

Therefore, he is also going to follow this list to learn.

But looking at the remaining four points of energy, Brother Xiao Yi had a little headache.

There's only four hours left to settle in!

As for replenishing energy.

Stumped to go to the back mountain at night to see if there are any ghosts?

For the time being, he didn't turn on the state of concentration, Yi Xiaochuan flipped through "Probability Theory and Mathematical Statistics", and found that he could understand it without relying on the system, but the efficiency was very low.

Advanced mathematics is fully comprehended, mathematical analysis is also digested and absorbed, advanced algebra, ordinary differential equations, are thoroughly studied, with Yi Xiaochuan's current attainments in mathematics, in the Department of Mathematics to be a scholar is stable.

Let's learn on our own......

Put the four points of energy first, maybe after the upgrade, the code cracking will also consume energy!

If you don't have energy, if you get a waste skill, wouldn't you be even more panicked.

Compared to calming down and studying, the ghost must be more difficult to catch and more dangerous.

From seven o'clock to ten o'clock in the evening, for three hours, Xiao Yi forced himself to finish reading "Probability Theory and Mathematical Statistics" with the greatest perseverance, and began to brush "Theory of Real Variable Functions", and did the exercises at the back of the book, made a few mistakes, and did some knowledge points that were not thoroughly understood.

Compared with entering the meditation, it is a bit painful to brush books with ability, and the memory and comprehension are not thorough.

【Opened Subject: Mathematics LV0 (99/100%)】

Steady, unchanged.

"It is difficult to complete all undergraduate mathematics courses in order to achieve LV1, complete graduate courses LV2, doctoral LV3, well-known professor LV4, and have a major breakthrough in mathematics LV5?"

In the moonlight, Otogawa thought secretly.

Today's one-day harvest, the 99% progress is progress on the surface, in the invisible and imperceptible places, the brain is developing little by little, memory, comprehension, creativity and so on have been strengthened.

But this 1% seems to be stuck in a bottleneck.

Stumped on my brain development has reached the peak of undergraduates?

Hey, it's a joy to think about!

Treat yourself to a ...... in the evening

The moonlight was hazy, and the aroma of food in the night cafeteria was already seducing Brother Xiaoyi, and suddenly, a terrible scream of extreme fear resounded through the quiet campus......
