"Far." Lin Yujing immediately replied, "I want to sleep in."

"Ahem..." The old man coughed again, "You... are quite annoying."

"Hehe." Lin Yujing said with a silly smile, "Liar."

The old man blushed and turned his head to avoid looking.

Hold on.

For more than a year, the character of the intimate librarian has been carefully cultivated and cannot be destroyed.

"Yu Jing, I can only say that the people you met before were not very good." The old man took a deep breath and had the courage to look at Lin Yujing, "A true good friend will not do it because you are too outstanding.

And those who are jealous of you will not dislike you because you are too bad. Although you went to a school that is not worthy of you, you must have friends who are worthy of you."

"Well..." Lin Yujing slowly lowered her head, "Before, there were some..."

"Then there are now." The old man nodded at the table, "If they leave you because of this nonsense, it can only be said that they are not worthy of you."

"..."

"Also, about the chemistry competition." The old man cleared his throat and said, "It's really not important. Just respect your own attitude. The only thing I can say is that what you really want to do,

There are many difficulties, no, there are simply countless difficulties, not an exaggeration, but truly countless.”

"Yeah." Lin Yujing also nodded.

"Among these countless difficulties, some will give you more headaches than chemistry. In fact, these difficulties include countless chemistry problems." The old man raised his silver eyebrows, "At that time, you will also choose this way.

What? Only focus on the part you like, only the part that goes well?"

"Well..." Lin Yujing lowered her head and pointed her fingers, feeling entangled.

"Haha, I said it too harshly, don't feel pressured." The old man's tone gradually softened, "In the end, it's just a chemistry competition. It doesn't necessarily have much to do with your future. There's nothing wrong with whatever you choose.

...Speaking of which, you are so unhappy, what happened to you?"

"He is the most annoying." Lin Yujing tilted her head.

"Okay..." The old man rubbed his head, "It can't be that...he participated in the competition, right?"

"……Um."

"Hehe." The old man became cheerful again, "That's interesting. That kid is not afraid of difficulties. I'm afraid he will slap you in the face with a certificate later."

"Well..." Lin Yujing clenched her fist fiercely, "Even if I hate chemistry... I'm still much better than him..."

"Not necessarily, competition can improve very quickly."

Just as he was talking, the most annoying sound came from the door of the library.

"Huh, that's so uncreative. I knew it was here."

"!" Lin Yujing was furious, glared at her, picked up her schoolbag and ran away.

But her movements gradually slowed down and stopped.

Also walking in together were Qiao Bixia and Xu Mengxi.

Qiao Bixia scolded as she walked away: "I'm just surprised. I just left you, Sister Xia, alone. What's there to talk about with this old...teacher?"

The old man felt offended.

What is she going to say?

old man?

Even so, he still raised an eyebrow at Lin Yujing and smiled, then picked up a large pile of documents and escaped into the Scripture Collection Pavilion.

At this moment, Xu Mengxi also ran over, took Lin Yujing's arm and shook it: "It's true...it's obvious that I'm unhappy, but in the end you want me to comfort you in turn, huh."

"Oh." Lin Yujing scratched her face and opened her mouth, not knowing what to say.

All I know is that I'm not that unhappy anymore.

Qiao Bixia also pulled out a chair and sat down: "Tell me about you, Li Zheng, don't you know yet? Can he speak human language? Has he ever spoken human language? What kind of aura of genius, what kind of sting, what is wrong with his brain?

Bar?"

After saying that, Qiao Bixia hugged Lin Yujing, hugged her chest, and pulled her in hard: "I'm just greedy for your body, don't you understand?"

"Uh huh..."

The suffocating feeling came back.

"Okay, Sister Xia." Xu Mengxi persuaded her away as usual, and simply squeezed Lin Yujing, sat on a chair with her, raised her hands, and pinched Lin Yujing's face from left to right.

"Pfft..." Lin Yujing was unable to resist, her entire face was flattened, and her eyes were turned into "~".

Xu Mengxi was also very addicted to pinching it. She laughed while pinching it: "Even if it really stings, so what? It still hurts when eating peppers. Doesn't the more you eat, the more addictive you become?"

"~" Lin Yujing was actually very happy being pinched.

"Attention, this is a knowledge point." Li Zheng suddenly came out, put down his schoolbag and said with a smile, "Spicy food is not about taste, it is about pain. When eating spicy food, the pain stimulation will stimulate the body to secrete some hormones, which not only makes people appetite

If you open it wide, you will become addicted. So here comes the question, what is the molecular formula of chili pepper..."

"Stay there!" Qiao Bixia pushed her over with a palm.

"I see..." Li Zhengcang panicked and fled to the Sutra Pavilion, "Is it true that no one is interested in the molecular formula of capsaicin..."

"Go away, go away." Even Xu Mengxi couldn't bear it anymore.

"Uh huh!" Lin Yujing also raised her fist.

Deep in the bookshelf.

Two lonely men bumped into each other.

The old man and Li Zheng looked at each other and smiled, both bitterly.

They are all just tool people.

"Just in time to return the book." Li Zheng said, "My schoolbag is outside, but I don't dare to go there now. I'll do it later."

"It doesn't matter." The old man put down the documents and glanced at the bookcase, "There are a few copies of Asimov..."

"I'll read it later." Li Zheng raised his hand and said, "When I read science fiction recently, I felt that my knowledge was not enough, and I didn't understand many parts."

"For example?" The old man became interested.

"General relativity." Li Zheng pursed his lips bitterly, "The special theory of relativity is barely understandable. It means that mass and energy, time and speed can be converted into each other."

"Not bad, this summary is already very good." The old man nodded in approval, "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 bars."

"Hey, you don't need to study so deeply. You haven't even mastered basic mathematical tools." The old man said and started searching on the bookshelf. "Have you learned about gravity?"

"I learned that there is a gravitational force between objects, and the size of the gravitational force is proportional to the mass."

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

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

"Congratulations, this is physics." The old man said with an approving smile while flipping through the books on the bookcase. "If a person always asks why when he was a child, then he is a smart child. If a person keeps asking questions all his life, he will

He is a scientist."

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

"Yes, he is a smart child. 99.999% of them will not become a scientist's child." The old man smiled in confusion, took out a book with a yellow cover, and handed it to Li Zheng, his eyes inexplicably darkened, "But what if,

What if you didn’t stop asking, what if 0.001 took effect?”

Li Zheng took the book in a panic.

"From One to Infinity"

George Gamow

From one atom to the infinite universe.

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

Only then did Li Zheng realize that this was a comprehensive popular science book that was dedicated to explaining high-level theories in a concise and interesting way.

He soon found an explanation of gravity in 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, looking like an educator.

"Wonderful!" Li Zheng glared, "How do you prove it?"

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

"Teacher Xiao Tang is very good." Li Zheng asked while collecting the books, "Why do you keep asking around?"

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

"Everything is fine." Li Zheng seemed to sense something was wrong.

"There's always something bad, right?"
