The three students tried one by one, and from the beginning, they picked up the crystal cup and were trembling, but afterwards they were completely shocked.

Xu Bin was here to mess around, but at this moment he asked with a serious expression: "Story, how dare you ask why?"

"Students ask for advice."

The three of them bowed to ask for advice.

What is this?

This is arrogance at the beginning and respect at the end.

Chen An said lightly: "This is knowledge. It contains what it takes to burn candles, what will become in the cup after burning, and why that change can cause water outside to rush in."

"Sit back."

Chen An started teaching.

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

The three students shook their heads in a daze. They knew about this kind of life phenomenon, but they didn't know the reason.

Chen An smiled and said, "That's because the burning of candles requires air. What is air? It's something that we have within our reach, what we breathe..."

The three students were stunned.

This is definitely a lesson that subverts their perception.

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

Chen An looked at him and felt that the word "stupid bird flew first" was correct.

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

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

"Then the cup becomes negative pressure...negative pressure... these things have to be told slowly to you."

"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, the water is directly sucked in."

Chen An slowly explained the principle of this experiment and even explained the concept of negative pressure, but the three of them looked confused and clearly didn't understand anything about air.

"The air cannot be seen, but if you cover your mouth and nose with something, you will know what air is."

There is no better way to verify than this.

"Woooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

He continued to explain, Su Yan blocked his mouth and nose with his sleeves, and then moaned.

This is...sincere.

Chen An signaled him to take it down, and then asked, "How does it feel?"

"Bully, panic."

"Pussy? Just panic. It can be seen that after being isolated from the air, you can't breathe."

The three of them were still a little doubtful, and Chen An smiled and said, "You can try it yourself when you go home."

Xu Bin said, "Storytelling, my house doesn't have a crystal cup."

Chen An sighed, "You must learn to be compatible. Without a crystal cup, the cup sucks water in, and there will be less water outside. Can't you see it?"

Xu Bin's face turned red and he stood up and accused him of crime.

After half an hour of a class, Chen An said with a smile: "It's all today, come again tomorrow."

The following is Confucianism, and I still have to do something, and I didn’t give Chen An extra time.

He walked out of the classroom with a cloth bag on his back, and the three students stood there without saying that they were respectful of teachers and education.

On the left side of the Imperial College is the Imperial College. Chen An saw Guo Qian when he came out.

In the huge Imperial College, there are only three students attending classes, and there are more officials than students.

Guo Qian bowed and said, "How about the waiter?"

He didn't use his superiors and subordinates to greet him, he just respected him.

Chen An smiled and said, "I'll wait and see if you give me a wine."

Guo Qian said in surprise: "Those students didn't send you?"

The first class, the new professor, don’t you send it out?

What about politeness?

What about the politeness of our country's sub-school?

Guo Qian was furious and prepared to deal with the three people.

Chen An stopped him with a smile and said, "This class has said something simple. They are afraid they will be stunned for a while and there is no need to worry about it."

He bowed his hand and left, swaying his backpack at his waist.

"Simple? How could you be dazed?"

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

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

In the past, these students ran out after class, for fear of staying in the classroom. Today, this is a bit weird!

"Hey! I'm afraid it's fake."

Xu Bin sighed quietly, and Guo Qian quietly retreated after hearing this.

Finally, three students were left to study miscellaneous studies, but looking at this... they didn't trust Chen An and miscellaneous studies!

But this matter cannot be handled bluntly...

Chen An was young and couldn't bear to bear to face. Forget it, I'll stop him.

When he went back, he found several professors and told them not to mention any matters related to Shen An and miscellaneous studies in class later.

...

"Really or not?"

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

Yang Zheng felt that this matter was a bit unreliable: "I'm afraid there was a ghost in his plate or candle."

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 said something about Chen An.

Su Yan next to him packed up his things and left with his back.

"Su Yan, where are you going?"

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

Xu Bin thought about it and packed up his own things.

Later, the three found Chen Ben and took leave.

“Why?”

Chen Ben was furious and thought that most of the students had taken leave. You three were the face left by the Imperial College for Chen An, and they were going to take leave too?

Once you leave, there is no student in the Imperial College. What's going on!

Xu Bin lowered his head and said, "The story of Shen Shu frightened the students."

Yang Zheng also said: "The story of Shen Shushu is scary, and students are now absent-minded."

These three people really looked like they were having problems and were absent-minded.

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

The three of them said goodbye, Chen Ben went to find Guo Qian and smiled bitterly: "Sacrifice, what did Chen An teach? He actually scared the students. The officials are worried that he is teaching... something that is taboo!"

Guo Qian pondered for a while: "This matter...it won't happen. I will talk to him at that time. After all, he is a smart person, so he will definitely not make a taboo."

Chen Ben sighed: "I am afraid that no one will come for his class tomorrow."

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

All the students from the Imperial College ran away. The news came, and the monarch and ministers were discussing matters.

"puff!"

Zeng Gongliang has always been a mature man, 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 holding back his laughter, he said, "Your Majesty, Chen An is young, you must leave some face for him."

Zhao Zhen nodded and smiled and said, "I won't care. If the students are gone, with his temperament, he will probably come back by himself and never go to the Imperial College again."

The king and his ministers laughed for a while, and then they dispersed.

Chen Zhongheng stayed at the end. He stood in front of the hall, squinted his eyes and murmured: "If Chen An could not even teach the students of the Imperial College, how could Zhao Zhongzhen and Zhe Kexing obey him? Wang Rong, such a proud and arrogant person, also highly praised Chen An..."
