"Teacher, you said that sound has speed, so what is its speed?"

Summer.

It is not okay to blindly take cultural classes.

The five little ones still have to strengthen their physical exercise.

Otherwise, how to charge into battle in the future.

Royal Forbidden Garden.

Everyone came out together to learn to ride a horse.

The voice of the crown princess Su also came from the side.

Li Zhong looked at the five little ones who could basically sit firmly on the horse, and also said, "Have you noticed the thunder?" ”

"Thunder?"

"Usually when there is thunder, do you always see the light first, and then hear the sound?"

Then the crown princess Su seemed to understand something.

"But how do you measure this?"

Li Zhong smiled bitterly, "This really can't be measured." But you can guess that thunder usually occurs at a certain height in the sky, and you can calculate it by measuring this altitude by dividing it by the time it takes for the sound to reach your ears. The speed of the sound is about 100 zhang in the blink of an eye. ”

After finishing speaking, Li Chong said to Li Chengqian on the side: "Your Royal Highness the Prince, take care of your crown princess." ”

Li Chengqian: "? ”

Su Shi also looked at Li Zhong suspiciously.

Li Chong said: "If she continues to ask like this, everything I know will be asked by her." And it's an equestrian lesson today! Originally, I just wanted to teach you for a month so that you could understand the true face of this world, but now that I am teaching more and more, this makes my pressure suddenly become greater. ”

"So next, I have to say ugly things in the front, what I can teach, almost all of them are almost finished, and after that, you go back to the East Palace, and the five little ones continue to learn literacy."

"Of course! It's not that I don't like your questions, but you can always come to me with any questions in the future, it's just ...... I really don't have much new knowledge to teach you now. ”

"Next, you can explore it yourself. This world is actually quite wonderful, and there are many magical places. All I know is a tiny drop in the ocean. ”

Su Shi looked up and said, "Teacher, you are too modest. ”

Li Chong: "Learn to ride a horse." ”

Then Su followed Li Chengqian to the side to practice horseback riding.

……

this year.

Li Jing was awarded the title of Duke of the Kingdom because of his meritorious worship of Shangshu's right servant.

And Li Chong's side, although he only recited a poem, the rank of this civil official was still raised by several levels.

It's the name of this doctor, it's not very good.

"Nine years of Zhenguan."

"This year is the ninth year of Zhenguan."

Princess's House.

Li Lizhen didn't know what he was feeling.

Isn't it normal to celebrate the ninth year of Zhenguan this year?

Li Chongzai thought in his heart, 'If it is according to history, Emperor Taishang Li Yuan should die in this year, and then Empress Changsun will die in the next year. ’

'What's next...... You have to keep an eye on the eldest grandson queen at all times. ’

"This year is the ninth year of Zhenguan, what's wrong?"

I saw Li Lizhi into his arms and said.

Lee scratched her waist and made her laugh uncontrollably.

"This year is the ninth year of Zhenguan, that is, nine years have passed."

“？” Li Li was puzzled. And then he said, "You're talking nonsense. ”

'There's not much time left. ’

Or rather...... That's actually pretty good. ’

'It's over, the ninth year of Zhenguan is 6xx years? ’

As I got older, my memory began to deteriorate. ’

In Li Chong's mind, there were one hundred and eighty pieces of information transmitting minute by second, and in Li Lizhen's eyes, there was only his beautiful and contemplative face.

Holding Li Chong's face with his hand, Li Lizhi also asked very strangely, "Why don't you grow a beard?" All men in Datang have beards, and only the inner servants do not have beards. ”

Li Zhong listened to her question......

Truly!

That's a problem!

How to say this, Li thought about it for a while, and said: "I think that if I grow a beard, I will get old, and I am not old now." But I have to admit that in two years, I will be thirty, and it seems that it is time to grow a beard. ”

Li Lizhi drew a beard on the side of his mouth with pink fingertips, imagining the appearance of a colt with a beard.

It felt like it was suddenly ugly.

Well!

If you have a beard, you do look a little old.

"In two years, you'll be seventeen?"

"Hmm."

"That's still too early."

"What's early?" Li Li was puzzled.

And then......

Li Chong whispered something in her ear.

I saw Li Lizhi's face rubbing it, and it turned red.

……

And maybe it's because Li Zhi already has a playmate now.

So......

Li Tai's eldest son, Li Xin, didn't seem to be forced to stay in the palace by the eldest grandson.

All I can say is...... That's a good thing.

Because to be honest, it is quite troublesome to take care of the children and manage the harem.

"Why did the prince suddenly ask about this? Don't...... The crown prince also wants to teach the son of King Yue with him? ”

I saw Empress Changsun smile and say to Li Chongdao.

Actually, don't say it, she still has some expectations.

Li Chong replied: "No, I just suddenly heard others talk about it, and then I knew that King Yue had an eldest son at such a young age, and for a while, I felt a little surprised." ”

"It's rare that you have time to come to see me, the queen mother, what's the matter?"

Empress Changsun always felt that there must be something wrong with these two people coming suddenly.

Li Lizhi said bluntly: "What's the matter, we just miss the queen mother." ”

Li Chong: "That's right! It's just to say hello. Has the queen's qi disease recidived recently? ”

The two of them are mysterious.

In the evening, Empress Changsun told Li Er about it.

Through Li Er's understanding of Li Chong, he quickly guessed what was going on.

Because Li Chong once said that in the second year after the death of the emperor, the queen also died.

Come to think of it, that's probably what happened.

He simply followed Li Chong's words and said: "Since they all let Guanyin have a good rest for a while, then Guanyin and you can take a good rest, and the Emperor Taishang will not have to go for a while." ”

Empress Eldest Sun immediately said, "How can this be done?" ”

Li Erdao: "Why can't this work, there are many slaves and maids on the Emperor Taishang's side, and you are not inferior to Guanyin." The most important thing for you now is to take care of your body. ”

In order to deceive Empress Changsun into believing it, Li Er also said: "Look, your face seems to have become a lot haggard recently. ”

Empress Eldest Sun hurriedly picked up the bronze mirror and took a photo, and hurriedly asked, "Is there one?" Peony, you see, don't you? ”

also asked about the slave on the side.

Li Er glanced at the slave maid called Peony, and the slave maid also immediately understood, and said crisply: "There is a little." It may be that the queen hasn't slept much lately. ”

Li Er said: "Look, even the slaves and maids say so. ”

Empress Changsun put down the bronze mirror, "But Emperor Tai's condition doesn't seem to be getting better recently." ”
