The banquet lasted until the next morning.

Of course, a child like Li Chengqian would have been driven back to sleep a long time ago.

It seems that this banquet is also used as a dividing line.

The Tang Dynasty before and after began to become a little different.

Of course!

This is just a hunch on the part of Li Chong.

……

Time can dilute everything.

Including Li Zhongzhong's guilt about the Turkic matter.

Academy.

The model of the sun, moon and stars he wanted had already been made.

Actually, nothing else is difficult.

It's just that how to divide the gears to be accurate seems a little difficult.

In fact, this uses the ruler and gauge diagram above mathematics.

Similar to how to draw an isoheptagon.

Of course!

This is the most formal.

It's not so formal, just a rough idea.

In fact, don't look at this as just a small toy, but it also contains the ancients' understanding of mathematics and astronomy.

If this thing is put in the future generations, I don't know how those experts and netizens will blow it.

However, Li Chong was thinking about how this thing could give full play to its greatest value.

And then......

Soon he was depressed again.

With the attitude of the ancients who did not attach importance to science at all, the value of this thing is extremely limited, even if it is maximized.

It is better to write a sentence on the song, Your Majesty must be diligent in government, love the people, and bring more fame to yourself.

The people around him will definitely applaud him for his daring to speak out.

"Forget it!"

"Let's keep it for now!"

……

Summer.

But the weather is still hot.

Speaking of which......

Is it possible to get some saltpeter to make ice?

He understands this!

Soon!

Li Chong found another craftsman and ordered him to go down.

To do things under Master Li, you must be all-round, even if you are not all-round at the beginning, but slowly later, you will train yourself to be all-round.

Li Chong, on the other hand, put a low table next to him, on which tea was boiled, and watched the breeze in the courtyard blowing the treetops and the rustling of leaves.

It feels like a good day is coming!

……

City.

With the entry of more and more Hu merchants, now, people are also shouting, showing a lively scene everywhere.

In addition, this year, the efficiency of silk reeling in every household has been improved, and more silk has been made, so everyone is more willing to consume.

A lot of things, when they first come out, don't actually reflect any effect.

But after a long time, the effect will come out.

Merely......

This will certainly also make some businessmen who are very good at opportunism see business opportunities.

For example, if you buy raw silk at a low price in Chang'an City and then ship it to other places, the difference may be a lot.

The cake is made, and the person with the slippery head can always get the big head.

And the rest of the honest ones can only drink soup.

But it's not bad.

After all, in the past, I didn't even have to drink the soup.

In light of this.

All walks of life in Datang seem to be slowly getting better.

So......

Li Er also made a decision!

He planned to let Yan Lide rebuild Luoyang Palace for future tours.

In fact, you don't have to think about it, this will definitely be opposed by the courtiers.

After all, the courtiers of the Tang Dynasty have not been corrupted.

Sure enough!

Zhang Xuansu objected to the matter.

Li Er had no choice but to give up.

After giving up, he came to Li Chong.

The car drove directly to the door of the Academy of Sciences.

The eldest grandson Wuji and Wei Zheng also came with him.

"The people are the source of the country."

Li Er stood at the door and looked at these five words.

Then he joked with the eldest grandson Wuji and Wei Zheng: "How can this be said as if it is me, I am the people, and the people are me." ”

Because his name is Li Shimin.

Eldest Sun Wuji felt that his joke was a bit cold, but he still smiled categorically and said, "This Li Chong is a sycophant." ”

After that, he said to the guard at the door, "Okay, go and call your dean out." ”

The guards were scrambling to get inside.

Li Er stopped him.

said: "No need, I also want to see what Li Chong is usually doing." ”

And then......

……

That's right!

Li Chong usually sits in the courtyard drinking tea, with his right hand supporting his cheeks, looking idle.

On the surface, he looks like he is in his twenties, but in fact, his state of mind is no longer the state of mind of this age.

Li Er also took off his shoes and quietly touched them.

The people behind him who came with him didn't dare to make the slightest sound.

"Alas~ boring!"

Li Chong was stretching his waist while thinking about Li Bai.

To be honest, he was quite envious of Li Bai for being able to go everywhere.

I envy him even more for having the perseverance to be fearless of hardships, and to always run around without his wife and children all year round.

At least......

He didn't. Unless he is given a teleportation golden finger, otherwise, he will never leave Chang'an easily.

After all, there is no need to look for guilt everywhere when eating and drinking well in Chang'an.

But there is also a possibility.

In the Tang Dynasty, the hotel industry and the horse rental industry were already quite developed, as long as there was money, no matter how long the road was, it was not a problem.

If you think about it this way, it seems that there are many things, and it makes sense.

For example, if you have money and can have hot water, food and drink at any time, it doesn't matter.

Then this made Li Chong can't help but say with emotion, "Zhaozhao has Tang, and heaven is for all countries." Bustling and prosperous, glorious for thousands of years. ”

After that's all that.

Li Chong also sang.

is what he once told Li Er before, saying that it is really the song of the loser, "The forbidden court is in spring, the warbler feather is covered with new embroidery, and the grass is skillful to fight with flowers, and only bet on the pearls." ”

Until the singing is over.

Only then did Li Chong realize that there seemed to be an extra person in red and yellow clothes behind him.

Li Chong's face was instantly hot.

Hurriedly got up and saluted: "Minister, Li Chong, I have seen Your Majesty." ”

"This song is good!" Li Er nodded in affirmation.

The eldest grandson Wuji also joked: "But when did the prince and master become a woman, and he still 'took care of the residual makeup day and night', 'dancing in front of the emperor or something'." ”

Li Zhong despises him, uneducated is uneducated, is that what he is talking about, that is the concubine of the harem.

It's just that the eldest grandson Wuji obviously knows, but he still wants to ridicule him, so it's useless to reason with this kind of person.

It's better to just ignore this kind of person: "Why is Your Majesty here?" ”

Li Er said with a smile on his lips: "Passing by, by the way, let's take a look at what you usually do here." ”

"Ahem!"

Li Chong was a little embarrassed, but when he thought that as long as he was thick-skinned enough, no one could do anything about himself, so he said, "Then Your Majesty has seen it now." ”

even brought Li Lizhi out.

Li Lizhen also looked at him from behind.

But think about it, Li Er does have the habit of taking the princess out on a tour.

Li Er looked at the delicate cups and teapots on the table, and then looked at the deep environment around him, and said, "You are usually idle. ”
