In the library, the old man is sitting at the table and reading documents.

suddenly.

"Well……"

A magazine was picked up on the table.

When the old man looked up, he saw Lin Yuejing picking his schoolbag across the table.

"Yo, what's wrong today?" The old man lifted his glasses, ""Hmm" is so weak."

"Hmm..." Lin Yuejing put the schoolbag on one side and sighed, "I'm not happy."

The old man took off his glasses with a smile: "That kid is annoying you again?"

"No... not all." Lin Yuejing's head was on the table, looking at the sneakers dumbfounded. "I don't know, I don't like it, I'm not happy."

The old man looked very happy.

The girl in trouble, how beautiful it is.

But after all, he is not Sun Leyang. He knows how to manage facial expressions. At this time, his face is empathetic.

"Don't think about it if you are not happy~www.readwn.com~ The old man got up and said, "How many new Asimov books have I entered, I'll bring them to you? "

"I've seen them all." Lin Yuejing said.

"Then what do you want to see, I'll find it for you."

"Thank you teacher, if you don't need it, you want to be quiet."

"Okay..." The old man then sat back at the table again, "It stands to reason that the museum is closed at 6 o'clock, and I'm fine today. I'll postpone it for you. How long I want to stay.

"Thank you teacher..." Lin Yuejing stared at the shoes and sighed again.

...

In the classroom, Li Zheng screamed out.

"Ren Da Fu? Just **** you?!"

Fortunately, there was no one else in the classroom, otherwise Li Zhengren would collapse again.

Zhang Xiaoke blushed: "What do you mean by acridine? People are very good in junior high school, OK?"

While she was talking, she got up and ran to the door, shut the door to death,

"That is to say, you turned to Sakura Lake because you couldn't stand the bottom?" Li Zheng stared at Zhang Xiaoke and doubted her IQ again, "You can make such a decision, you are too..."

"Warning you, shut up!" Zhang Xiaoke locked the door, walked back to the table, lowered his head, and suddenly grieved, "You don't know how terrible those people are, and get along with more than 1400 Lin Yuejing day and night, you suffer Did you get it?"

"Um..." Li Zheng gasped, "I understand it if you say that."

"I...have nothing more to crave..." Zhang Xiaoke gritted his teeth and hit the table with a punch. "Just want to be a person."

"Sakura Lake will satisfy your wishes."

"You must help me keep it secret." Zhang Xiaoke turned to stare at Li Zheng. "I must have passed the top 50 in the midterm. This would have been a very happy thing. If people let me know that I was attached by Renda , It will be jokes instead."

"Got it." Li Zheng suddenly glared. "No wonder, you know so many people who participate in the Olympic Games, there is still one."

"Well, I said that long ago, my network at Quanjijing High School is beyond your imagination."

"In this way, the wish you owe me can be fulfilled." Li Zheng nodded. "You have worked hard and helped me get the exercises of the Renda University competition class. The more the better."

"Ah? What are your wishes?"

Li Zheng quickly drew out a small book: "In the basketball game, you lost your bet, but you forgot?"

"Uh." Zhang Xiaoke scratched his head. "But... so many papers... I gave it to you either?"

"Don't you have a deep network?"

"Deep is deep...but the relationship is strange..." Zhang Xiaoke blushed and didn't dare to say anything.

Just my IQ.

Would it be weird to have a contest roll suddenly?

Li Zheng then picked up the phone: "Forget it, I'm looking for Chen Jinyu."

"Don't! I want it!" Zhang Xiaoke immediately held him down, "Master, why are you playing this suit, is it interesting?"

"It's just stimulating your potential." Li Zheng pursed his lips with a smile. "Look, how many words have you memorized in these days?"

"Oh, that..." Zhang Xiaoke scratched his head and said, "I feel that progress is not small."

Li Zheng joyfully abducted and got up: "Well, I will not supervise you this weekend, come on, work hard, be strong."

"!!!"

When I walked to the door, as soon as I opened the door, I saw a huge figure.

"I... didn't hear anything." Qiao Buxia was a little embarrassed, and said with a smile ha ha, "After school, one man and one woman, closed the classroom, discussed learning, no problem, ha ha, no problem.

"What do you say..." Xu Mengxi got out from behind her, and she was in a much better condition at the moment, but when she saw Li Zheng, she hid back again and sighed in a low voice, "Quietly gone..."

"This..." Li Zheng also scratched his head. "Hanging her for three days is a bit too much, or forget about it for a long time."

"You are Lu Bu, IQ is really not good." Qiao Bixia scolded, "Don't you know the quiet and delusional problems? Just a little bit of trouble, and you are so troubled by life, I don't know how to say you."

"Cough..." Zhang Xiaoke carried his schoolbag at this time and passed his head with his head down, "You talk, I'm going..."

"Bye." Qiao Bixia leaned close to Xu Mengxi's ear and said, "These two goods are very attached... Brains are drawn..."

"Woo woo..." Zhang Xiaoke wanted to cry without tears, and did not have the courage to resist, so he ran away with his fists clenched.

...

In the library, Lin Yuejing had been lying down for 20 minutes.

Writhing.

Unhappy.

The old man looked at the documents one by one, looking like nothing.

Lin Yuejing was even more angry when he saw him like this.

He laid his head on the table and stomped hard.

"Huh?" The old man quickly took off the mirror, "Want to talk?"

Lin Yujing twitched, and then murmured: "Hate chemistry."

"Hi, who doesn't hate it."

"I don't want to participate."

"Then don't race."

"They have to ask me to participate." Lin Yuejing stomped several times. "Nasty, nasty, nasty."

"Just about this?" The old man chuckled. "Your troubles are really hard to solve."

"There are others..." Lin Yuejing's legs softened again, and his voice resembled a mosquito. He did not, "Good friends...maybe starting to hate me..."

"What did you do?"

"I..." Lin Yuejing thought for a long time before reluctantly covering his face, "too...too clever..."

"Cough..." The old man coughed twice with his heart dry. "I also start to hate you."

"I don't want it... I tried as much as possible... I didn't show much, and I didn't even say much..." Lin Yujing turned his head, rested his chin on the table, stared at the front, and puffed out, "Puff puff puff Puff puff……"

"Oops..." The old man looked at her, a little bit unable to withstand it, so he had to look sideways to ensure a decent expression, "What does it mean not to behave?"

"It's just..." Lin Yuejing said with a few more chuckles.

"As soon as I act, I will be disliked, and my speech will be disliked. Anything I say will be disliked."

"For example... 100 points."

"I said no review."

"It will be annoying."

"It's a lie to review it."

"It will be annoying."

"Speaking of test questions is simple, it will be annoying."

"It's hard to deceive people, and they will be hated."

"Just...whatever is wrong..."

"Hey... this is the master is lonely." The old man sighed, "Why not try to go to a better school, there may be people like you there."

"Far." Lin Yuejing answered immediately, "I want to sleep lazy."

"Cough..." The old man coughed again. "You... are annoying enough."

"Hey." Lin Yuejing smirked, "Fooling."

The old man blushed and turned his head away from his eyes.

Hold on.

For more than a year, the design of the intimate librarian has not collapsed.

"Yue Jing, I can only say that the people you met before were not very good." The old man took a deep breath before he had the courage to look to Lin Yuejing, "True good friend, not because you are too good And those who are jealous of you will not dislike you because you are too bad. Although you go to a school that is not worthy of you, there must be friends who are worthy of you."

"Hmm..." Lin Yuejing slowly lowered his head. "Before, some..."

"That's there now." The old man nodded at the table. "If you leave because of this fart, you can only say that they don't deserve you."

"..."

"Also, something about the chemical competition." The old man coughed his throat, "It's really not important, just respect your attitude. The only thing I can say is that what you really want to do, Difficulties, no, it's just countless difficulties, not exaggerated rhetoric, it's really countless."

"Well." Lin Yuejing also nodded.

"Of these countless difficulties, it is inevitable that you have a headache than chemistry. It is even said that these difficulties contain countless chemical problems at all." Grandpa Yinmei raised his eyebrows, "At that time, you will also choose so What? Only focus on the part you like, only the smooth part?"

"Um..." Lin Yujing lowered his head and put his fingers on it, caught in a tangle.

"Oh, I said too much, you don't have pressure." The old man's tone gradually softened. "In the final analysis, it's just a chemistry competition. There is not much inevitable connection with your future. There is nothing wrong with your choice." ...In other words, you are so unhappy, what the **** is wrong with you?"

"He hates it the most." Lin Yuejing turned his head away.

"Okay..." The old man rubbed his head. "Wouldn't it be...he took part?"

"……Ok."

"Hey." The old man rejoiced again, "That's interesting, the kid isn't afraid of difficulties, and I'm afraid I won't get a certificate to smash your face."

"Hmm..." Lin Yuejing clenched his fists hard, "Even if I hate chemistry...I'm much better than him..."

"Not necessarily Yo, the competition can be improved very quickly."

As I said, the most annoying voice came from the library door.

"Huh, it's too creative, I knew it was here."

"!" Lin Yuejing frowned, staring at it, and ran away after picking up his schoolbag.

But her movements gradually slowed down and stopped.

Qiao Bixia and Xu Mengxi also walked in together.

Qiao Bixia scolded as she walked away: "I was so strange, I left your sister Xia ignored, and this old...the teacher has something to talk about."

The old man felt offended.

What is she going to say?

old man?

Despite this, he raised a brow at Lin Yuejing, then picked up a large stack of documents and escaped into the Tibetan Scripture Pavilion.

At this time, Xu Mengxi also ran over and took Lin Yujing's arm to shake: "Really... I was obviously unhappy, and I was asked to comfort you in return, hum."

"Ah oh." Lin Yue scratched his face, his mouth open, and didn't know what to say.

I only know that I am not so upset.

Qiao Bixia also took a chair and sat down: "You talk about you, Li Zheng, don't you know yet, does he speak human language? Did he speak human language? What aura of genius, what stings, and a pit in his brain Right?"

After all, Qiao Bixia hugged Lin Yuejing in one hug, nestled in her chest, and squeezed inwards: "I am greedy for your body, don't you understand?"

"Hmm..."

The feeling of suffocation is back.

"Okay sister Xia." Xu Mengxi persuaded as usual, squeezing Lin Yuejing, sitting on a chair with her, raising her hands and pinching Lin Yuejing's face.

"Puff..." Lin Yuejing was unable to resist, his entire face was flattened, and his eyes were reduced to "~".

Xu Mengxi was also very addicted, and smiled while squeezing: "Even if it really hurts, how about it? It still hurts when you eat chili, isn't it more addictive?"

"~~~" Lin Yuejing was pinched so happy.

"Attention, this is a point of knowledge." Li Zheng suddenly came out and put down his schoolbag and smiled, "Spicy is not taste, but pain. When eating spicy, because of this pain stimulation, it will stimulate the body to secrete some hormones, not only appetite. It’s open and it’s addictive. Then the question is coming, may I ask the molecular formula of pepper...

"Bian'er stayed there!" Qiao Bixia pushed over with a palm.

"I know..." Li Zhengcang panicked to the Tibetan Scripture Pavilion, "Is nobody really interested in the molecular formula of capsaicin..."

"You go, you go wow." Even Xu Mengxi couldn't bear it.

"Hmm!" Lin Yuejing also waved his fist.

Deep in the bookshelf.

Two lonely men collided together.

The old man and Li Zheng smiled at each other, also bitter.

They are just tools.

"It just happened to return the book." Li Zheng said, "My schoolbag is outside, but I dare not go now, wait a moment."

"It doesn't matter." The old man then put down the documents and scanned the bookcase. "There are a few Asimov..."

"Let's watch later." Li Zheng raised his hand. "When I was reading science fiction recently, I felt that my knowledge was not enough. Many places didn't understand it."

"For example?" The old man came to take an interest.

"General theory of relativity." Li Zheng pouted his mouth bitterly, "The special theory of relativity is barely understandable, that is, mass and energy, time and speed can be converted between each other."

"Yes, this summary is already very good." The old man nodded approvingly, "This refining ability is fine."

"But general relativity, textbooks are basically not discussed, I don't understand the video on the bar."

"Eh, you don't need to study so deeply, you don't even have basic math tools." The old man said, looking on the bookshelf. "Did you learn gravity?"

"Study, there will be gravity between objects, and the magnitude of gravity is proportional to the mass."

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

"Of course." Li Zheng immediately asked, "Why? Why is there gravity? Why does it increase with mass?"

"Congratulations, this is physics." The grandpa laughed while turning the book on the bookcase, "A man always asks why when he was a child, then he is a clever child. What a person has been asking all his life, he will It’s a scientist."

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

"Yeah, it's a clever kid, 99.999% won't be a scientist's kid." The old man was puzzled and pulled out a yellow cover book, handed it to Li Zheng, his eyes inexplicably deep, "But just in case, In case you didn’t stop asking, what if 0.001 came into effect?"

Li Zheng took over the books in a panic.

"From One to Infinity"

George Gamov-

From a single atom to the infinite universe.

The old man patted Li Zheng's shoulder: "This book will not help you pass the exam, but you have the opportunity to ignite the 0.001%."

Li Zheng only understood at this time that this is a comprehensive science popularization book, which specifically explains those taller theories in a streamlined 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 because of the massive objects, bending the surrounding space and time. 】

"This is the general theory of relativity." The old man smiled with a straight face, like an educator.

"Wonderful!" Li Zheng glared, "How to prove it?"

"Where do I understand, I'll be a librarian." The old man said, putting on his glasses again, and pulled out a pen and asked, "How is your new class teacher?"

"Teacher Xiaotang is very good." Li Zheng asked while collecting the book, "How are you always asking?"

"Ask so much." The old man asked, biting off the pen cap. "Don't hold back, teaching quality, management methods, communication skills, let's talk about it."

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

"There are always bad things?"

Li Zheng subconsciously sniffed his head.

In fact, there are some shortcomings.

Forget it, let her keep it secret.

"It's perfect in every way." Li Zheng wiped his nose and said, "Our midterm exam will definitely break out in our class."

"It's boring." The old man put away the book in a boring way, but he was still stubborn and asked with raised eyebrows, "I heard that your kid is going to play a game?"

"Your news is really well informed."

"Then wait." The old man was busy again. "There are some inorganic chemistry in it. I can see if I can find it."

"Thank you very much." Li Zheng moved at the same time, took out his mobile phone, opened the book list sent by Sun Leyang, "I have searched for all, these dozens of books, also helped to find chant."

"..." The old man is well-informed and has never seen such a shameless person.

Not to mention, the school library is also really in stock. After searching around, I found two Sun Leyang's designated textbooks.

When Li Zheng finished the borrowing and returning procedures, Lin Yuejing and Xu Mengxi were reconciled.

Actually, it didn't break, it was all caused by Li Zheng's blind beep.

After all, if you can't bear Lin Yuejing's aura of genius, I'm afraid I won't be friends anymore.
