More than a dozen phone calls were made by the second child, Zhang Fatzi, and Chen Bo, and Weixin also had a lot of information, asking Yi Xiaochuan what was wrong, whether he had really encountered a ghost.

Dr. Chen went to see the boss today, and it was not good to call and disturb, so on the prestige @ the whole group, report safety.

Zhang Yue replied in seconds, chatting a few words, Yi Xiaochuan couldn't stand the chat without punctuation, and made an excuse, so he revealed the matter of turning off the mobile phone.

Seeing that the second child in the Northeast had not replied to the message, Yi Xiaochuan made a special call.

The call you dialed is not answered. Please dial later!】

The second child is missing?!

Brother Xiaoyi, who knows that this world will change greatly, thinks a lot, Huang Daxian that the second child met last night is definitely an extraordinary creature that the system says in just a few words.

A weasel who can speak human language, and he speaks pure Mandarin, and the transcendent creature didn't run away.

So, will the second child be in danger?

Looking at the second child's last reply time on prestige, Yi Xiaochuan dispelled his worries, at seven o'clock, the sun is drying his buttocks, what danger can there be!

That Wong Tai Sin is very clear.

It's dark, don't go out!

And from these five words, it can be seen that the night may no longer belong to human beings. There are many unknown creatures that will haunt the lightless land, and the night will be their playground and shelter, and even the umbrella for hunting humans......

"The second child is also a person with a great opportunity! That Wong Tai Sin begged him for a seal, and he should be sheltered for a ...... or two."

calmed down the good mood, and the mobile phone battery also rushed to 42%.

took the mobile phone and went downstairs, and under the unkind gaze of the dormitory uncle, Brother Xiao Yi screamed in his stomach and rushed directly to the cafeteria.

At this time, the exam has begun, and there are naturally few people in the cafeteria, no need to queue, a pancake fruit, eggs and ham, two eggs are specially added, and then a cup of soy milk.

Hot, fragrant, eat while walking, target library.

You still have to read books, and you have to go behind your back with the system, and you are still the ones who suffer.

Since the golden finger cannot be changed, then lie down and enjoy!

Having said that, the golden finger of this black technology system, the peak creation of the Fourth Age, should be very thick and hard, and it should also be very comfortable!

The pancakes are freshly made, and the lettuce wrapped in them is creaking after biting, and the crispy fritters are clicking, and with the eggs and ham sandwiched inside, I swallowed it after dividing it by two.

Halfway through, Yi Xiaochuan returned to the cafeteria and handed over ten yuan and a pancake fruit......

Then "crunch" gobble up the food, hand over the money, and have another pancake fruit, remember to add two eggs......

Under the surprised gaze of the pancake aunt, Yi Xiaochuan ate three pancake fruits in a row, and then he felt a little full.

Think about it, there are three more big steamed buns, put them in the backpack, and be prepared.

After graduation, the campus card has been cancelled, so is the library still in?

Normally, you can't get in.

The easiest way to solve it is to borrow a card and swipe it.

"Ding!"

Otogawa walked into the library, which he had probably not been to more than ten times in four years.

Mathematics books, on the second floor.

During the exam, there were not many people, and Yi Xiaochuan wandered among the tall bookshelves for a while, and finally took a book of high mathematics, at least he had studied.

Advanced Mathematics (Volume I), published by Tsinghua University Press in 2009, authors Zhang Xueshan, Li Lu, Shen Yiyi, etc.

The pen and scratch paper were just bought outside the cafeteria, and after looking for a corner, Yi Xiaochuan opened the high math book blankly.

Back then, I was also a scumbag who could score 63 points!

Pass by strength.

Let's take a look at the questions first!

What am I doing?

Is this a high number?

It's hard that I'm not even as good as a scumbag, and I've become a student cripple?

Let's start from the first chapter!

Chapter 1: Functions, Limits, and Continuity.

Looking at it seriously for three minutes, Yi Xiaochuan felt that his attention had reached the limit, and after five minutes, his feet were shaking unconsciously, and for ten minutes, the elementary school girl sitting next door was dressed very coolly!

Ying Ying shakes the ......

Hey, hey, hey!

Ahem!

Glancing at the properties panel.

【Opened Subject: Mathematics LV0 (0/100%)】

There are no changes.

As for the harvest, the attribute panel can't be seen by others, only my little brother Yi can see it, this is a big harvest, it has been determined.

Brother Xiaoyi, who knows what level he is, has decided to use his skills, and he has ten points of energy left, and he can enter the meditation for ten hours.

No more delays, settle down.

In an instant, Yi Xiaochuan felt that the world had changed, all the noise disappeared in his ears, all the colors faded in the corners of his eyes, and there was nothing but the book of "Advanced Mathematics (Volume I)" in front of him.

The only book I am in the world.

I don't know the passage of time, I don't know the people around me, the footsteps, the sound of flipping books, everything, disappear into the world of Otogawa.

Time passed minute by minute, but there were more people in the library, and some students finished the exam in advance, and they came to recharge while the library was still closed. Second, the scumbags who don't have exams today are also late, even if they can't learn anything, but sitting in the library, they can always bring mystery confidence to tomorrow's exam. Third, the library is air-conditioned!

Otogawa didn't notice that there were more people around him, and he was still immersed in the ocean of mathematics without selfishness.

It wasn't until he turned to the last page that he finally broke away from his meditation.

At that moment, my head was a little dizzy, my heart was beating violently, I felt like a drum, and then I felt hungry.

Fortunately, he was well prepared, and swallowed three big steamed buns, almost choking him to death.

Then looking at the properties panel, Otogawa finally smiled.

【Subjects Opened: Mathematics LV0 (17/100%)】

And the time to brush a copy of "Advanced Mathematics (Volume I)" is only one hour!

I love to learn!

I want to be a top student!

I want to enjoy the caress of the golden finger!

There is still an hour and a half to close, and "Advanced Mathematics (Volume II)" starts.

The elementary school girl who was dressed in cool clothes on the opposite side looked up at Yi Xiaochuan, and felt that the person in front of her was a little weird, a high math, and I read it like a novel for an hour, and I didn't even move the pen, and more importantly, you were still addicted to it.

Now I have taken "Advanced Mathematics (Volume II)", and I still have a confident smile on my face, which I really don't know.

Stumped, this is what the legend calls self-congratulation?

The elementary girl retracted her gaze, picked up the cute HelloKitty pink water cup and took a sip of water, and then studied the calculus problem in front of her......

It's so difficult! The elementary school girl pouted, although she was not a big beauty facing up in her eighties, but she was also very cute.

Once upon a time there was a tree called High Mathematics, and there were many people hanging on it, and next to it there was a grave called Calculus, in which many people were buried.

In the world of concentration, time always flies quickly, until someone pats Brother Xiaoyi's shoulder, which makes him wake up from that state of selfless concentration.

"Classmate, it's noon, and the museum is closing. Aunt Librarian said.

Came back to his senses in a daze, with a little dizziness, the high concentration of the brain, resulting in a little low blood sugar, if it weren't for the support of the three big steamed buns, Yi Xiaochuan felt that he should have fainted by now.

"Ah, I'm sorry, Auntie, I forgot the time, you let me slow down, my head is a little dizzy......"

"Blood sugar is low! I use my brain too much, I'll get you a candy, my daughter is also low blood sugar, I always have this sugar with me...... Auntie has been working in the library for so many years, and this is the first time I have seen a student who can read a math book so attentively. Give ......"

After taking the fruit candy from Aunt Library, Brother Xiao Yi finally relieved himself.

I thanked him and walked out of the library, the sun was dazzling and the heat wave was hitting.

This is the difference between purgatory and heaven compared to a library.

"Advanced Mathematics (Volume II)", which was not completed in an hour and a half, calculus, double integrals, and Taylor Fourier series, these are much more difficult than the first volume.

But even if you don't finish brushing it, the experience points you get will increase more than in the previous book.

【Opened Subject: Mathematics LV0 (37/100%)】

"Eat first, eat and sleep, nourish your spirits, and continue to read books in the afternoon......"

Yi Xiaochuan puffed himself up, and then took out the mobile phone that was turned to silent as he walked, but there was no phone, but the prestige was a red 99+......
