After negotiating the conditions, Feng Yangui stretched out his hand to collect money. Zhang Shuhai gave.

Then, he changed his seat and became a middle-aged man with a feather fan in his hand and a scarf on his head, and sat down.

"Chen Daoyou, can we go to class now?"

Chen Qinghe nodded.

Then, she took the initiative of the words in her hands.

"Zhang Shuhai Daoyou, I see that you are a person who loves to learn, so let's give you a little chemistry and biology by the way, so that you can understand the other essence of this world."

After speaking, Chen Qinghe began to talk about the periodic table, the half-life of each element, as well as cytoplasm, nucleus, cell fluid, neutrons, and protons、......

In an hour, Chen Qinghe threw down nearly 500 terms and concepts that were quite unfamiliar to Zhang Shuhai and Feng Yangui in one go.

Zhang Shuhai was also randomly selected and asked to answer a few test questions in the public examination, so that he could find the rules and find out the correct answers.

The more Zhang Shuhai listened to Chen Qinghe, the faster his body became feverish.

His body was always hot, and his heart was excited, and he had an inexplicable sense of frustration.

He had lived for so many years, and for the first time he felt that he was illiterate, an idiot, a fool, and did not understand anything.

Zhang Shuhai felt it so deeply, and those people outside who had found a way to overhear it were also frowning and worried.

Hu Xianling looked at Qi Wuxian and said, "Qi Wuxian, you heard all the things she just said, right?" ”

Qi Wuxian nodded and said, "I heard it." ”

Hu Xianling looked at him suspiciously: "Then do you understand?" ”

Qi Wuxian shook his head. "I didn't understand anything, I didn't even understand what she was talking about."

Hu Xianling touched his chin with a puzzled expression, "Qi Wuxian, what kind of X-rays, gamma rays, black holes, wormholes, space-time collapse, neutrons, protons, electrons, periodic table half-life ...... you just said, what are these things?" ”

"How do I feel that after staying here for so long, I have become a countryman who doesn't know anything?"

“…… Perhaps, this is the practice that the side door and the left path practice every day, right? Noticing the Hu County Order in front of him, his brows were about to knot, and Qi said this sentence in a low voice.

Hu Xianling listened, thought about it seriously, and shook his head gently.

"No, I can feel that some of the things she just said are close to the law and the truth. That's something we never recognized. ”

"Zhang Shuhai, a bookworm, has a characteristic, he was born to pursue the law, so as to become a part of the law. He is now so interested in Chen Qinghe, which shows that Chen Qinghe has a huge attraction in his eyes. ”

Qi Wuxian looked at Hu Xianling and said, "Lord County Order, do you want to kill her now?" ”

Hu Xianling's eyes widened, and he was extremely surprised.

"I—What am I killing her for? Speak quietly, but don't let anyone else hear. ”

He already knew that he couldn't beat her alone, so why did he have to fight hard?

He was just trying to know what she was doing now. So as to understand where she came from, what her purpose is, what exercises she usually practiced, and where her weaknesses are.

Only when he has a comprehensive understanding of her can he attack her at that time.

……

When Chen Qinghe was in the second grade of primary school, he began to learn Olympiad mathematics.

She experienced it firsthand, something that impressed her very deeply.

In the second grade of primary school, she did not learn the Olympiad math in elementary school, but in junior high school. At that time, even if she was particularly good at math, every time she learned the Olympiad knowledge in elementary school, she felt that her head was hot, as if it was about to explode.

She knew then that she should be growing her brain.

She has experienced such a thing, and she has reason to believe that Zhang Shuhai and Feng Yangui, who had been listening to her lecture carefully just now, would only change more in their minds at this time than she had at the beginning.

Chen Qinghe's guess was right.

Feng Yangui had been sitting there quietly, looking at the notes he had made in his hand, thinking seriously.

And Zhang Shuhai's whole body has already turned hot and red.

He felt like his brain was going to smoke.

With his big round eyes, he stared at the piles of notes in front of him, constantly recalling their basic concepts.

And that periodic table,...... Some of him already understood, some of which he still didn't.

It stands to reason that as an immortal cultivator, he has already reached the point where he will never forget.

But I don't know what's going on today, just by reciting the chemical periodic table in front of him, he has already memorized the time of a cup of tea. But in addition to calcium, iron, zinc, selenium, sodium chloride, oxygen, and ...... In addition to the more than 20 elements memorized, he had to hold this periodic table to remember.

Thinking that Chen Qinghe was sure that the substances in this world were made up of these elements, the 8 hearts inside Zhang Shuhai's body began a series of connections and analyses.

Soon, he suddenly judged that what Chen Qinghe said seemed to be true.

recalled that Chen Qinghe told him before, "In every element, there are such things as neutrons, protons, and electrons, and the microscopic world that is invisible to the naked eye is very grand." Just like the saying goes, one flower is one world, one tree is one Bodhi ......", Zhang Shuhai suddenly opened his mouth and asked.

"Chen Daoyou, you told me earlier that the macrocosm can be infinitely large, so big that we can never explore the boundary. He also said that the microcosm can be infinitely small, so small that we can never explore its boundaries. ”

"Do you mean to tell me that this world is infinite?"

Chen Qinghe thought for a moment and nodded.

"I guess so. Boundless and endless, always untouchable. ”

When Feng Yangui heard this, he suddenly interjected.

"It's like what mortals often say, there are people outside of people, and there are mountains outside of mountains, right?"

Chen Qinghe smiled, "It should be about the same, right?" ”

Zhang Shuhai was engrossed in the three-hour class today, and his mind was completely messy.

At this time, when he heard Chen Qinghe talk about those truths, he was chattering, and his eyelids were tired and fighting.

Sure enough, learning to read is to overhang the head and be piercing. It's about learning from the dead.

Zhang Shuhai sighed in his heart, and at the same time sent Chen Qinghe and Feng Yan out of the book world.

He's so tired today that he needs a good night's sleep here.

……

was suddenly sent out by Zhang Shuhai from the bright and white book realm, Chen Qinghe and Feng Yangui were a little surprised.

Feng Yan returned thinking that Zhang Shuhai would not release them, but he didn't expect him to release them suddenly.

Seeing that Chen Qinghe was expressionless on his face and sat there quietly, Feng Yangui hurriedly asked with concern.

"Qinghe, are you uncomfortable somewhere? Hungry or thirsty? ”

Chen Qinghe shook his head. "Not really. I just suddenly thought, this place is pretty good. It's suitable for us to read. ”

"It's also suitable for you to write a book."
