Chapter 256 Stunning
Silence, still silence.
Three hundred students stared at the glass on the table in amazement.
This glass was naturally amazing, but now they completely ignored the existence of the glass.
Their eyes were just staring at the water that suddenly rose.
If the person standing in front of them was not the King of Yan, but a Taoist priest, they would definitely believe that this was a sorcery.
Wang Chong sat in the middle of the first row.
He had been waiting for this day to come.
At this moment, facing the expectant eyes of the King of Yan, he suddenly blushed.
Why did the candle go out? Why did the water rise?
He really had no idea.
After all, since he was born, no one has performed this in front of him.
"No one can answer?" Zhao Xu asked again.
All the students remained silent, looking shocked.
"Then let me explain this phenomenon. The air we breathe contains many components, one of which is called oxygen."
"It is this oxygen that allows you and me to survive, and it is this oxygen that allows everything to burn. So when the oxygen in the cup is exhausted by the candle, the candle goes out, and water takes the place where oxygen should have taken." Zhao Xu said slowly.
"Oxygen."
The word was immediately deeply engraved in the students' minds.
The door to a new world seemed to open in front of them as King Yan told them.
It turned out that their breathing was not so simple.
"Oxygen is invisible and intangible, but it really exists. There is an introduction to oxygen in the book I gave you. You can read it yourself." Zhao Xu showed the textbook in his hand.
The content in the text alone will only confuse these students who don't know any scientific knowledge at all.
So he did this experiment.
The students opened the book and read it, and they had a deeper understanding of oxygen.
Then Zhao Xu brought a pot of vinegar and boiled it.
He put his hand in in front of the students, which caused a burst of exclamations from the students.
Street performers sometimes perform this, and they always thought that the performers really knew magic.
After the King of Yan asked them to put their hands into the pot one by one, and after experiencing it, he explained a word to him, boiling point.
Only then did they understand that everything has a boiling point, the boiling point of water is 100 degrees, and the boiling point of vinegar is 60 degrees.
Then Zhao Xu talked about some other basic scientific concepts.
This was also the main purpose of his first class, to overturn their understanding of feudal superstition.
Otherwise, they would still live in the previous ignorant world.
Only when they are curious about new things will they actively learn.
"So this is science."
After one class, the students felt that their world collapsed.
What they once believed to exist were just some simple scientific phenomena.
Thunder and lightning are not thunder and lightning, but the collision and friction of clouds.
The earth is not square but round.
Until Zhao Xu left with the textbook, the students in the school were still reluctant to leave.
They needed to calm down and think about everything they heard in the past half hour.
Wang Chong was the first to come to his senses. After all, he had not been in the Armory for nothing.
Before leaving, the King of Yan gave him a task.
Standing up and facing the students, he said, "Let's discuss what His Highness said. Today's task is to memorize and recite the concepts in the book. I will check it in the evening."
The students nodded.
The King of Yan appointed Wang Chong to be in charge of the school, and they naturally obeyed his orders.
This side.
Zhao Xu left the Armory and went to the Government Affairs School and the Military School.
In the Government Affairs School, he first taught agriculture.
For example, the characteristics of various grains and how to plant them, requiring officials to go down to the fields to guide the people in farming.
There are many officials in office in the Government Affairs School.
After listening to the class, they have to go back to the government office to work, which is considered to be learning and practicing at the same time.
In the Military School, he talked about battlefield command and taught the generals to recognize flag language.
In ancient battlefields, the transmission of orders on the battlefield has always been a problem.
In addition to using messengers, he believes that it is necessary to popularize flag language in the army.
What the eyes see is faster than what the legs run, so that it will be easy to command on the battlefield.
In this way, he taught one hour of classes in each of the three schools every day, which is half an hour.
If there is extra time, he will add classes temporarily.
The rest of the time is for them to study on their own, and through discussions among students, they can master the content of this hour.
The places they don’t understand will be raised in the class on the second day.
The reason why he arranged it this way is that the students are generally over the age of sixteen, and there is no need to teach them every detail like elementary school students.
So in this one-hour class, he stuffed a lot of knowledge and let them digest it slowly by themselves.
Busy for a whole morning.
Zhao Xu returned to the palace, and he was thirsty at this time.
He hurriedly asked Luan'er to pour him some water.
Before he finished a glass of water, Feng'er informed him that Chang Wei wanted to see him.
Zhao Xu thought to himself that he really couldn't be idle for a moment.
After drinking the rest of the water in one gulp, he asked him to come in.
After a while, Chang Wei came in with big strides.
Although it was still winter, Chang Wei's forehead was covered with sweat.
Seeing Zhao Xu, Chang Wei said anxiously: "Your Highness, something big has happened!"
