Datang: At the beginning, Princess Wencheng was robbed

Chapter 156
Wei House.

Somewhere in a courtyard.

Behind Wei Yan is a white board, and Wei Yan is standing in front of this board, teaching Wei Zhizhi.

"Today's first class, first of all, let's get to know the universe we live in, and how did we come to be?"

……

Li Xueyan and others came to listen to the class curiously.

I really fear that the world will not be chaotic.

With a large group of servants, they all looked at their father and son eagerly.

If I had known earlier, Wei Yan shouldn't have let them listen.

"Father, don't we study the scriptures?"

Wei Yan then said: "Um...you are still so young, what you learned is of no use."

"Oh."

"Then what is the universe?"

Wei Yan: "The so-called universe... I won't tell you what it means in ancient books and classics. If you have time, you can learn it as your homework. I'll just say, the universe I want to talk about."

"The universe I'm talking about includes what you can see, such as the sun, stars, moon, and even what you can't see, the sum of everything except the sun, stars, and moon."

"That is to say, you and I are living in the universe right now, and there are all kinds of things in this universe."

"Today, I just want to tell you something about the universe."

Then Wei Yan began to give various examples.

As small as the flowers planted by his second mother, Xinxing Princess, as large as the sun on the ground, these are all things contained in the universe.

"So, what do these things have to do with it?"

……

Starting from the flower, the flower is planted in the soil.

The person stands next to the flower and keeps drawing horizontally and vertically.

All kinds of characters and pictures were drawn by Wei Yan.

Draw until the sun, stars, moon.

Finally, he said: "This seems to be the universe that we can roughly understand from the naked eye."

At this time, Wei Zhizhi also said: "Father, you just said that the universe includes what can be seen and what cannot be seen. These are all things that can be seen, so what are the things that cannot be seen?"

Wei Yan said: "For example, sound, also called sound waves, and electromagnetic waves."

"Electromagnetic waves?"

Wei Zhizhi looked puzzled.

Wei Yan: "That's right, but because you can't see it with the naked eye, you don't have to think about seeing it, but there is one thing that can prove its existence. Come up, father will give you something fun."

then……

Wei Yan gave him a walkie-talkie.

Wei Yan: "Now take the things in your hand and walk behind your mother, um, go further. Go back a few steps."

When Wei Zhizhi stood still, Wei Yan said: "Am I far away from you now?"

Wei Zhizhi nodded.

Wei Yan: "If under normal circumstances, I want to talk to you, then do I have to stand here and talk to you very loudly so that you can hear me?"

"Ah."

Wei Zhizhi continued to nod.

Wei Yan: "But if electromagnetic waves are used, even if I'm in your mother's house now, I can still talk to you, believe it or not."

"..."

Then Wei Zhizhi definitely didn't believe it.

Wei Yan said, "Take that thing and stand there, don't move. I'll go and come back."

Immediately afterwards, Wei Yan walked out of the academy pavilion in the side courtyard.

Not long after, Wei Yan disappeared.

Everyone is waiting for Wei Yan.

Until it was almost the time to go to Li Xueyan's house.

soon……

A voice came from the walkie-talkie in Wei Zhizhi's hand.

Wei Yan: "Hey, can you hear me?"

Wei Zhizhi was not frightened, because he didn't know what was going on at the first moment.

Wei Yan said again: "You press the red thing on the left side of the walkie-talkie, press it down, and then talk, and when you finish speaking, release it again, and you can talk to me."

Wei Zhizhi tried to follow suit, "Father, is it you?"

Wei Yan: "That's right, it's for the father. After you finish a sentence, you have to add "I'm finished" at the end. Please reply when you receive it, otherwise others will not know whether you have finished speaking or whether you missed anything in the process. .I'm done talking, please reply when you receive it."

Li Xueyan and the others are going crazy!
Knowing how you are still playing with such a dangerous thing, quickly throw this damn thing away.

Wei Zhizhi replied: "Okay. I'm done talking, please reply."

"Know it, throw this thing away."

"Mother, why?"

"This thing looks scary!"

"Forehead……"

……

Soon.

Wei Yan came back again.

Seeing that the mother and son seemed to be arguing, he said, "Have you heard it? This is something we can't see."

Seeing that Wei Yan was back, Li Xueyan seemed to feel relieved suddenly for no reason.

Wei Zhizhi immediately replied happily to his father, "I heard everything! But my mother won't let me hold this thing."

Wei Yan: "Why?"

Li Xueyan: "That's not because I'm afraid of danger."

Li Xueyan must have a reason.

Wei Yan said quickly: "He said that he is your son, but he is not my son. How could I harm him. But if you know it, you should take it back."

"Oh."

Wei Yan: "Following the content just now, why can we talk to each other even though we are so far away?"

"It's something that you and I can't see with our naked eyes, but it does exist in the universe."

"Of course, the principle of this is actually a bit profound. Now you just need to know that there is such a thing between heaven and earth."

"And... the electromagnetic waves we used just now are not naturally generated electromagnetic waves, but artificially generated."

"In the universe, there are actually many things that are not created artificially, but humans, because they discovered this law, used this law to complete the conversation like you and me just now."

"Do you understand?"

"clear."

"Ok!"

Wei Yan nodded, and continued: "Now that you already know what the universe is and what it contains. Then let me ask you again, do you know how the universe came about?"

"It's as if you were born from your mother's belly, so who gave birth to the universe?"

Li Xueyan was embarrassed after hearing this, is this something that can be said to a child?
Wei Zhizhi directly shook his head.

Wei Yan also continued talking - from the creation of the world by Pangu to the Big Bang.

The knowledge Wei Yan possesses is so vast, you will never guess what he will say next.

Even Li Xueyan found it incredible after hearing his conjecture.

I don't know if Wei Zhizhi can understand.

Anyway...

Isn’t teaching this a bit beyond what a five-year-old child can accept?

Li Xueyan originally thought that it would be great if Wei Yan could tell Zhizhi the story of Kong Rong giving pears.Who would have thought that even she had never seen such a class.
