The three students tried it one by one, and they were trembling from the beginning of picking up the crystal cup to the complete shock at the end.

Xu Bin originally came to mix up, but at this moment, he asked with a solemn face: "Storytelling, dare to ask why?" ”

"Students ask for advice."

The three of them bowed down to ask for advice.

What is this?

This is the former and the latter.

Shen An said lightly: "This is knowledge. It contains what it takes for the candle to burn, what becomes in the cup when that thing burns, and why that change causes water from outside to rush in. ”

"Sit back."

Shen An began to lecture.

"We can find that when the candle is covered with a lid, it goes out, so why?"

The three students shook their heads in confusion, they knew about such a phenomenon in life, but they didn't know why.

Shen An smiled: "That's because candles need air to burn, what is air?" It's what we reach, what we breathe......"

Three students were already stunned.

It's definitely a lesson that changes their perceptions.

Yang Zheng and Xu Bin were in a daze, but Su Yan was stupid and recording.

Shen An glanced at him and felt that the word stupid bird flew first was really true.

"After the crystal cup covers the candle, it is buried in the water, and then the air cannot enter until it is burned out and the candle is extinguished."

Shen An said as he lit the candle, then closed it, and when it was opened, the candle went out.

"Then there was negative pressure in the cup...... Negative pressure ...... I'll have to tell you about these things slowly. ”

"There is a difference between the inside and outside of the cup after negative pressure, because ink water is used to seal the edge of the cup, so the water is directly sucked in."

Shen An slowly explained the principle of this test, and even explained the concept of negative pressure, but the three of them were all confused, and they clearly didn't understand any air.

"You can't see the air, but if you cover your mouth and nose with something, you know what air is."

There's no better way to verify this.

"Woooooo

He continued to explain, Su Yan blocked his mouth and nose with his sleeve, and then whined.

It's a ...... Sincerely.

Shen An motioned for him to take it off, and then asked, "How do you feel?" ”

"Stuffy, panicked."

"Panic? It's right to panic, you can see that when you are cut off from the air, you can't breathe. ”

The three of them still had some doubts, and Shen An smiled: "You can test it yourself when you go home." ”

Xu Bin said: "Storytelling, I don't have a crystal cup at home. ”

Shen An sighed: "You have to learn to be accommodating. There is no crystal cup, but the cup sucks the water in, and there is less water outside, can't you see? ”

Xu Bin's face turned red and he got up to confess.

For most of the lesson, Shen An said with a smile: "That's it for today, come back tomorrow." ”

The following is Confucianism, and I have to do something to make an article, so I didn't give Shen An extra time.

He walked out of the classroom with a cloth bag on his back, and the three students stood still, without saying anything about respecting teachers and valuing education.

On the left side of Guozijian is Taixue, and Shen An saw Guo Qian when he came out.

There are only three students in the huge Guozijian now, and the number of officials is more than the number of students.

Guo Qian arched his hand and said, "How about waiting for the edict?" ”

He didn't greet him with his superiors and subordinates, just respect.

Shen An smiled and said, "Just wait and see what the sacrificial wine is." ”

Guo Qian was stunned and said, "Those students didn't send you?" ”

The first class, the new professor, you didn't even send it out?

What about politeness?

What about the politeness of our eunuchs?

Guo Qian was furious, so he prepared to clean up the three people.

Shen An stopped him with a smile and said, "This class said something simple, they are afraid that they will be stunned for a while, so they don't need to care." ”

He threw his backpack around his waist.

"Simple? So how can you be in a daze? ”

Guo Qian walked to the edge of the classroom suspiciously, and quietly poked out half of his head to look in.

All three students sat in their respective positions in a daze.

In the past, after class, these students all ran outside, lest they stay in the classroom for one more, but now this is a bit evil!

"Hey! I'm afraid it's fake. ”

Xu Bin sighed faintly, and Guo Qian quietly retreated when he heard it.

Finally, three students were left to study miscellaneous, but it looks like this...... They don't trust Shen An and Miscellaneous Studies!

But this matter can't be handled bluntly......

That Shen An was young and reluctant to lose face, so the old man blocked him.

When he went back, he found a few professors and told them not to mention anything related to Shen An's miscellaneous studies in class later.

……

"Really?"

Xu Bin felt that this was like a dream, a dream that made people feel dizzy.

Yang Zheng felt that this matter was a little unreliable: "I'm afraid there are ghosts in his dishes or candles." ”

Xu Bin nodded and said, "Yes, otherwise how could such a miracle appear in the world." ”

The two found a reason, so they laughed and talked about Shen An.

Su Yan on the side packed up his things and left on his back.

"Su Yan, where are you going?"

"I'm going to take a leave of absence, go home and try it."

Xu Bin thought about it and packed up his things.

Later, the three of them found Chen Ben to take leave.

"Why?"

Chen Ben was furious, thinking that most of the students had taken leave, and the three of you were the face left by Guozijian to Shen An, and you also had to take leave?

As soon as you leave, not a single student in the Guozi Prison is gone, what's going on!

Xu Bin lowered his head and said, "Shen's storytelling class frightened the students. ”

Yang Zheng also said: "Shen's storytelling class is scary, and the students are now in a state of distraction. ”

These three people really looked like they had a problem and couldn't give up.

Chen Ben's anger dissipated, and he waved his hand and said, "Go, go, go." ”

The three of them said goodbye, Chen Ben went to find Guo Qian, and said with a wry smile: "Sacrificial wine, what did Shen An teach?" It frightened the students. The lower officials are worried about what he is teaching...... What a taboo thing! ”

Guo Qian stroked his beard and pondered for a while: "This matter ...... This will not happen, the old man will talk to him when the time comes, but he is also a smart person, and he will definitely not commit taboos. ”

Chen Ben sighed: "Xia Guan is afraid that no one will come to his class tomorrow." ”

Guo Qian thought about it, and the two of them could only smile bitterly.

All the students of Guozijian ran away, and the news came, and it happened that the monarch and ministers were deliberating.

"Poof!"

Zeng Gongliang has always been old, but now he can't help laughing.

Han Qi laughed out loud.

Fu Bi's cheeks twitched, and when he saw that the official family was also smiling, he said, "Your Majesty, Shen An is young, and I have to save some face for him." ”

Zhao Zhen nodded, and couldn't help but smile: "I don't care, if there are no students to listen to the class, with his temperament, most of them will come back by themselves and never go to the Guozijian again." ”

The ministers laughed for a while, and then dispersed.

Chen Zhongheng stayed at the back, he stood in front of the hall, squinted at the front, and muttered: "If Shen An can't even teach the students of Guozijian, how can Zhao Zhongjun and Zhi Kexing obey him?" Wang Yan is such a high-minded and arrogant person, and he also admires Shen An very much......"

He sighed, "I'm afraid I don't know who is the fool!" ”

……

Xu Bin prepared the materials when he returned home, and then began the experiment in his room.

Because the cup was opaque, he closed the candle and stared at the water on the plate.

"It's time to go out!"

He didn't dare to blink, his eyes were sore.

"Huh!"

The water on the plate suddenly moved.

Xu Bin watched nervously, and even lay on the table, eager to stuff his eyes into the cup to see if he had sucked in water.

The cup was like a big mouthful, and suddenly it started sucking.

Xu Bin's breathing was suddenly short, he stared intently at the plate, and sweat gradually appeared on his forehead.

It's moving!

The water on the plate moved!

Xu Bin watched blankly until the water waves calmed down.

He only felt his hair stand upside down, and then slowly turned around to look.

There are no ghosts!

He did it a few more times, and every time......

He sniffed and cried out, "Mother! ”

His mother ran in and said anxiously, "What's the matter?" What's wrong? ”

Xu Bin smiled: "Mother, the child met a very powerful professor. ”

His mother breathed a sigh of relief and said, "The Guozijian has long since declined, and now that there are good professors, you have to study well." ”

Xu Bin looked at the extinguished candle and nodded, "Yes." ”

Early the next morning, Xu Bin set off with his schoolbag on his back.

Guozijian is now scattered and can't be managed, so they can go home wantonly, and their lives are quite leisurely.

As for the imperial examination, how can the current Guozijian have the luxury of hoping for any imperial examination.

It turned out that Taixue was at its peak, but in the trial in the second year of Jiayou, the Taixue students led by Liu Ji encountered Ouyang Xiu.

Lao Ouyang looked down on the so-called Taixue body, so most of the candidates who studied too much overturned.

Taixue collapsed.

Liu Ji was a little annoyed at the time, and before returning to his hometown, he said: "Keep the champion for my brother!" ”

This was regarded as a face-saving joke, and no one took it seriously.

But this year it was a big joke. Liu Ji knew that he had offended Ouyang Xiu, so he changed his name to Liu Hui, completely changed his style to the type that Ouyang Xiu liked, and then took this year's exam.

This year, Ouyang Xiu was the examiner of the palace examination, and he was greatly praised when he got Liu Hui's test paper.

What a talent!

Official, this Liu Hui should be the champion!

Zhao Zhen also nodded in approval, and then Liu Hui (Liu Ji) brother really became the champion.

But even so, Guozijian and Taixue still irreversibly collapsed and became a place that no one paid attention to.

Xu Bin entered the classroom, and Yang Zheng had already arrived.

"How?"

He asked.

Yang Zheng raised his head, and there was horror in his eyes: "Terrible! Horrible! This is the knowledge of the gods, learn it! ”

Xu Bin nodded and said, "Yes, you have to study hard!" ”

"You waited for yesterday's lecture, what did the edict say? I'm so scared that you'll go home sick after class. ”

The school is also a small society, and there will be classes as well.

The tall Liang Que is not only good at studying, but also good at fighting, so he is the boss in the current Guozi Prison.

He stood in front and said triumphantly: "If you don't go, you deserve it." Anyway, will you leave today? ”

Shen An has a class today.

"Don't go!"

Su Yan came, he said his opinion angrily, and then returned to his seat.

Liang Que scolded: "Fool! Who asked you! ”

Su Yan ignored him, and Xu Bin and Yang Zheng both shook their heads in unison.

"Huh!"

Liang Que was surprised: "You guys are ...... Lose your marbles? ”

Yang Zheng's eyes rolled and said: "The story doesn't allow us to leave, saying that if we leave, we will be unlucky to turn around." ”

"Hahahaha!"

Liang Que laughed and said proudly: "This is your calamity, you deserve it!" ”

After a class ended, Xu Bin and the three of them went out, and he said in a low voice, "You shouldn't say that." ”

Yang Zheng said proudly: "Let them be proud, we will get benefits, and everyone will think that the class taught by the book is not good......"

This product is small-minded, and he doesn't want others to share the benefits brought by Shen An.

When Shen An came, the students were still the same three, and the others were squatting somewhere else, preferring to brag and bask in the sun rather than come to listen to his class.

Shen An didn't ask, he stood on it and said, "From today onwards, I will teach you to re-understand this world." ”

"In every class in the future, we will teach half arithmetic and half of the rest, and you should take good notes."

Shen An took out the textbook he had compiled and began to teach.

"You should all know how to add, subtract, multiply, and divide, so let's talk about the equation ......"
