Learning Demon Cultivation System

"Not bad, this summary is already very good." The old man nodded approvingly, "This refining ability is fine."

"But the general theory of relativity is basically not discussed in textbooks, and I can't quite understand the videos on the bar."

"Hey, you don't need to study so deeply, you don't even have the basic mathematical tools." The old man said, looking for it on the bookshelf, "Have you learned about gravity?"

"Learned, that is, massive objects will generate gravity and attract surrounding objects."

"Okay, so what do you want to say about this matter?"

"Of course there is." Li Zheng asked immediately, "Why? Why do massive objects have their own gravity?"

"Congratulations, this is physics." The old man smiled approvingly while flipping through the books on the bookcase, "If a person always asks why when he was young, then he is a smart child. If a person asks why all his life, he will know It's a scientist."

Li Zheng was shocked: "I... I'm just a child..."

"Yeah, he's a smart kid, 99.999% won't become a scientist's kid." The old man smiled confusedly, pulled out a book with a yellow cover, and handed it to Li Zheng, his eyes darkened inexplicably, "But what if, What if you don't stop asking, what if 0.001 takes effect?"

Li Zheng took the books in a panic.

"From One to Infinity"

George Gamow -

From a single atom to the infinite universe.

The old man patted Li Zheng on the shoulder: "This book won't help you pass the exam, but it has a chance to ignite that 0.001%."

Only now did Li Zheng understand that this is a comprehensive popular science book, which is dedicated to explaining those high-level theories in a concise and interesting way.

He quickly found an explanation of gravity on the back of the book.

[Gravity is not an independent force. Its essence is that massive objects bend the surrounding space-time. 】

"This is the general theory of relativity." The old man smiled sanctimoniously, just like an educator.

"Wonderful!" Li Zheng stared, "How did you prove it?"

"How do I know that, I'm just a librarian." The old man put on his glasses again, took out a pen and paper and asked, "How is your new head teacher?"

"Teacher Xiao Tang is very good." Li Zheng asked while collecting the book, "Why are you asking all the time?"

"Why are you asking so much?" The old man bit his pen cap and asked, "Don't worry, let's talk about the quality of teaching, management methods, and communication skills."

"It's all good." Li Zheng seemed to sense something was wrong.

"There's always something bad about it, right?"

Li Zheng subconsciously sniffled.

To put it bluntly, there are indeed some shortcomings.

Forget it, let her keep it a secret.

"Everything is perfect." Li Zheng wiped his nose and said, "Our class will explode in the midterm exam."

"It's boring." The old man put away the notebook boredly, but he was still not dead-hearted. He raised his eyebrows and asked, "I heard that your kid wants to play a competition?"

"You are really well informed."

"Then just wait." The old man started to work again, "There are some books on inorganic chemistry in there, I'll see if I can find them."

"Thank you very much." Li Zheng was moved, took out his mobile phone, and opened the book list sent by Sun Leyang, "I've searched for everything, and I'll help you find these dozen books."

"..." Even though the old man is well-informed, he has never seen such a shameless person.

Not to mention, the school library really has the goods. After searching around, I found two textbooks designated by Sun Leyang.

When Li Zheng finished borrowing and returning the books, Lin Yujing and Xu Mengxi had reconciled as before.

In fact, there was no rupture at all, it was all disturbed by Li Zheng's blind beeping.

After all, if you can't bear Lin Yujing's aura of genius, you probably won't be friends long ago.

Chapter 94 My son is too old to hold it

Back home in the evening, full of food and drink, after a series of purchases, Li Zheng sat at the table, took out the competition paper he made at noon, and began to study the answer analysis.

But he quickly stopped.

motherfucker.

I can't understand the answer either.

He had no choice but to temporarily abandon this test paper, and instead opened the basic book on the basis of chemistry competitions - "Inorganic Chemistry".

This blue book "Inorganic Chemistry" can be described as a classic among the classics, even the school library has it.

Although in essence, it is already a college textbook, but because of the competition, high school students use it more.

Li Zheng didn't have any extra ideas. The first task for now is to complete the "Earth Demon Challenge", let's get chemistry to 200 first.

He opened the textbook and started from scratch.

This time learning, as stated in his brewing poems, learning against the wind is like shit.

It took more than 40 hours of vitality, plus a 100% increase in chemistry efficiency, to finish this textbook.

There are still a lot of knowledge points that I don't understand.

After all, the efficiency of self-study is no better than that of a famous teacher.

But it's not a good taste to study hard.

If you let the teacher take you through every hurdle, your ability to die will only get weaker and weaker.

Just like Lin Yujing, Xiao Fu was at ease, afraid of challenges, so he ran away immediately.

How can I read English papers in the future?

After despising him in his heart, Li Zheng grabbed Wangcai and rubbed it in his arms, before checking his study results.

【Chemistry: 153→159】

6 o'clock……

It seems that there is really a bottleneck.

For the inorganic part, it seems that we can only count on tomorrow's exercises.

Humph~

The phone screen suddenly lit up.

[Lin Yujing: . . . . 】

Li Zheng frowned.

Tell me, you have already sent messages, but only a series of periods.

How is that different from not sending?

Isn't this a waste of communication resources?

The entropy of the entire universe has been increased meaninglessly by you.

I've been studying inorganic chemistry for half a day and I'm tired enough, and I still have to use my brain to analyze what you're trying to say.

No matter, I'm not used to you.

Ignore you.

Soon, the phone rang again.

Humph~

[Lin Yujing: . . . .Book】

"Hmph." Li Zheng smiled with satisfaction.

Just say you can't get used to it.

This is not to speak honestly.

He just picked up the phone to answer.

[Li Zheng:? 】

[Lin Yujing: . . . . 】

[Li Zheng:? 】

[Lin Yujing: Don't learn from me (fierce)]

[Li Zheng: . . . . 】

[Lin Yujing: . . . . 】

[Lin Yujing: Send me the list of competition books. 】

[Li Zheng: Oh?Decided to enter?Figured out? 】

2 minute later.

[Li Zheng: Why aren't you talking? 】

[Li Zheng: How did you figure it out? 】

[Li Zheng: Tell me loudly, do you like chemistry? 】

(red exclamation point) [Li Zheng: 111]

[Lin Yujing has turned on friend verification, you are not his (her) friend.Please send a friend verification request first...]

Li Zheng stared.

I'll just make a joke.

Is it necessary to be so desperate?

He quickly sent a friend to verify.

[Li Zheng: Stop making trouble, here you go. 】

[Lin Yujing replied: Figured it out? 】

The application was rejected, Li Zheng scratched his head angrily, and applied again.

[Li Zheng: Pass quickly...]

[Lin Yujing replied: How did you figure it out? 】

Also dismissed.

Li Zheng suppressed his anger and applied again.

[Li Zheng: Don't bully people too much. 】

2 minute later.

[Li Zheng: I'll give you one last chance to pass within 3 minutes. 】

3 minute later.

[Li Zheng: I'll give you one last chance. I'm going to take a shower now. If I fail, you won't have my friend seat anymore. 】

Li Zheng came to the living room with a change of clothes in his arms, and threw his phone on the sofa.

Still used to you?

Ye Gucheng, do you really think I, Ximen Chuuxue, am reluctant to cut you?

After cursing a few words, he jumped into the bathroom to take a shower.

Not long after, the door opened.

"Huh..." Li Yi walked into the living room with tired steps, took off his windbreaker feebly, and hung it up.

There are a lot of temporary surgeries this week, even if he is crazy, he still can't stand it anymore.

Seeing that Li Zheng was taking a shower in the bathroom, he had no choice but to sit on the sofa.

Li Yi leaned back on the sofa, suddenly felt a pain in his butt, reached out and took out his hand, it turned out to be his son's cell phone.

Li Yi wanted to let it go, but suddenly his eyes flashed.
