Chapter 33

At seven o'clock in the evening.

Drag tired body back to the bedroom of Hao Yun, unexpectedly found no one in the bedroom.

But no wonder.

Today is the weekend. Zhu Kening has student union activities. Liang Ziyuan seems to have a guitar club or some kind of music club. Zheng Xueqian should go to the library to study himself.

It's said that the club has completely missed the new year

What kind of club did you add in your last life?

Frowning and thinking for a long time, Hao Yun simply shook his head and did not think about it. He skillfully climbed the ladder and turned over to bed, lying flat and entered the system space.

[item list: S-level treasure chest * 3]

I didn't expect it to be a treasure chest this time.

This kind of scraping music, which needs to be scraped again after the award, how can it feel like a Russian doll?

However, the S-level prefix logo, more or less let the physically and mentally exhausted Hao Yun feel a little comfort.

S-class gem?

Or some special ability?

Hope is a causal wishing machine without side effects

He muttered a few words in his heart. Lying on the bed, Hao Yun reached out and poked at the icon of the treasure chest.

[congratulations to the host for getting the advanced mathematics textbook full of Professor Lu's notes]

Hao Yun

What the hell?!

Before he could react, an ordinary high number book appeared out of thin air and hit him on the head.

"Shit..."

The tears of pain are almost squeezed out. Hao Yun reaches out his hand and looks at the culprit who hurt himself. He is almost not frightened by the content inside.

what the hell! It's full of them?!

Bear the pain will continue to turn the textbook back, Hao Yun's only feeling is like reading the book of heaven.

If you ignore the notes and just look at the printed form outside the notes, it's almost the same as the textbook he's using. Although there are some differences in typesetting, the basic knowledge points are almost the same.

According to this statement, will there be another generation of this person in the future? Discrete? Notes on probability theory?

Gan!

This guy is so good at pretending!

Vaguely feel that the name is a bit familiar, but can not remember where heard, Hao Yun brow locked thinking. However, at this time, the second line of pop-up window popped up in front of his eyes.

[branch line: study carefully and deeply understand the contents in the notes, and complete 100 thinking questions independently after class

[reward: Math attribute + 4]

Good guy

Add 4 attribute points directly?!

Originally, he wanted to complain, but when he saw the clearly marked task reward, Hao Yun couldn't complain.

Although he has no special interest in the course of mathematics, and even rejected it in his last life because of some unclear reasons, he certainly won't refuse anything that can improve his ability.

A hundred questions.

It'll take a little more time.

Moving his eyes away from this strange high mathematics textbook, Hao Yun continued to look at the remaining two treasure boxes.

This time, he understood that the treasure chest should be open with things that can be seen and touched, while the direct rewards for the task are those that only he can see.

Do you want to keep scraping?

Hao Yun's face hesitated.

If it's a book, it's OK to put a high point under the pillow at most. If a big guy comes out, such as "so and so's piano", it's not easy to explain, but it's life-threatening

Just at this time, footsteps came from outside the dormitory.

Hearing the sound of the door lock turning, Hao Yun was so excited that he stuffed the book under his pillow and hid it. Meanwhile, he lay flat on the bed. The whole set of action is completely out of instinct, flowing, at one go.

Almost at the same time, Zheng Xueqian with one shoulder bag and Liang Ziyuan with guitar came in from outside.

Looking at Hao Yun lying on the bed, Zheng Xueqian said hello with a smile.

"Oh, why did you come back so early today?"

Hearing Lao Zheng's voice, Hao Yun answered weakly.

"Tired, come back and lie down."

Tired?

Zheng Xueqian's heart suddenly tightened.

I'm afraid I've been studying all day

Especially when he just came in, he vaguely heard the sound of the pages rolling.

Is this guy studying in bed?

The more I think about it, the more I think it is possible. After playing in the library for several hours in 2048, he is more nervous.

Liang Ziyuan looked at the upper bunk and saw that this guy didn't seem to be joking. Finally, he put down the guitar which had just been put on his knee.

Although he thinks that he is a living and self-centered person and doesn't like to meddle in other people's affairs, it doesn't mean that he doesn't take care of other people's feelings at all.

He was able to tell the difference between "I can't stand it jokingly" and "I can't stand it physically".

If you are tired, have a good rest.

Without saying a word, humming an unknown minor, he took out the Yellow draft book and began to write some difficult staff and elusive sentences on it.

Zheng Xueqian, on the other side, hesitated for a long time about whether to disturb Hao Yun's sleep. Finally, he could not help asking.

"Brother Yun."

It's rare that Ziyuan brothers don't play the piano today. Hao Yun, who is very comfortable, answers lazily.

"Your father is here. If you have a fart, let it go."

"Grass! Believe it or not, I'll leave Lao Zhu's socks on your bed. "

On hearing this, Hao Yun was immediately happy.

"What? Do you want to help Lao Zhu collect socks? "

Probably was imagines in the picture to disgust, under the bed came a retch.

After a long time, Zheng Xueqian, who came slowly, put on a serious tone and continued to say.

"Come on, I won't talk nonsense with you. It's serious."

"You said

"Did you do the thinking problem assigned in senior mathematics class last time?"

Thinking questions?

Anything else?

Hao Yun frowned.

"Thinking about higher mathematics?"

"Yes, in Lao Li's class, didn't he leave a question on the blackboard?" Zheng Xueqian said painfully, "I've been in the library all afternoon, but I haven't finished it."

"Oh, you said that."

Hao Yun was vaguely impressed.

At that time, Zhu Kening also went to the toilet to deliver paper to himself. In that class, he was distracted all the time and didn't hear it clearly, but the thinking question was copied in the draft book.

But it seems very simple for him to remember

Is there only two or three letters in all.

Zheng Xueqian couldn't laugh or cry and said, "don't just write it out, have you?"

Hao Yun answered honestly.

"No

Zheng Xueqian

"What's the hurry?" Liang Ziyuan took a look at Zheng Xueqian and said calmly, "the next class is Tuesday. It's too late to write tomorrow."

Zheng Xueqian said with a bitter smile, "you don't know how difficult that problem is."

Liang Ziyuan: "no feeling."

Zheng Xueqian: "which step did you write?"

Liang Ziyuan: "solution."

Zheng Xueqian

Don't want to talk nonsense with this troublesome guy, Liang Ziyuan impatiently moved his eyes, looked up at the upper bunk, and shifted the focus of the topic.

"Brother Yun, do you want to sleep or not, I'll practice for a while?"

"I'm asleep. Good night, thank you."

He quickly pulled up the bed curtain, but Hao Yun didn't go to sleep immediately. Instead, he turned on the night light in the bed curtain and felt out the "advanced mathematics textbook full of Professor Lu's notes".

With a trace of curiosity, he opened the title page of the book.

Only the part with the name has been erased, leaving only a line of maxims written by the author himself——

Science changes the world, mathematics changes science

Hao Yun

ok

Whether or not mathematics has changed the world.

Hao Yun would like to call him the strongest!
