Shu An guided Li Shimin into his small courtyard, and Li Xiuning saw this second brother nodding slightly.

Although he knew that Shu An wanted to know some knowledge about geography, Li Xiuning had already told Shu An a lot before.

On top of the progress, there are much more students than those students in the academy, so naturally there is no need to participate.

However, this princess seems to be exhausted by cooking, so she has been trying to make food.

Of course, the current Li Xiuning is also self-aware, he will taste a few bites, if not, he will feed some cats, dogs, pigs and the like.

For these animals, it doesn't matter whether the food is good or bad, but the ability to eat enough is the key.

There was something strange about the same emperor's face, that is, his sister had never entered the kitchen.

But the current changes have made Li Shimin feel incredulous, but fortunately, Li Shimin didn't think much about this matter.

After all, if Xiuning didn't volunteer, then who would be able to let Xiuning enter the kitchen.

The cause and effect, Li Shimin also knew a little guess, it must be Xiuning who wanted to cook for Ya's father.

"Shimin, what is the matter with coming here?!"

Just as Li Shimin's thoughts were flying, Shu An's voice sounded.

"Father, please also give me some guidance, after the world map came out this time, it caused a lot of reactions."

This emperor did not hide anything, and even told everything in the court.

It can be said that Li Shimin doesn't know how he is going to leave at this time, the world is too big.

With the narration of this emperor, even Shu An was slightly stunned, and he didn't expect such a big reaction.

Although the mood can be understood, from Shu An's point of view, although Datang has the ambition to annex the world, it does not have the strength to match.

"There are some unfounded worries among the people."

"Although I know that the world is vast, in fact, Datang still takes its own path."

"You must know that there are still many countries around Datang, and the current HNA technology is also incomplete."

"Don't look at the Ming Dynasty, the navigation is relatively smooth, but in fact, it is all personal ability."

.......

After a long time, Shu An's voice began to sound, although HNA is good, but in fact, the risk is still too great in this era.

If it weren't for the potatoes before, even Shu An wouldn't want to take such a risk, but now Shu An still told Li Shimin about the risk.

Sure enough, Li Shimin was not a fool, and he couldn't help but show a wry smile on his face.

With the click of Ya Father, this emperor also woke up, and it seemed that he had overestimated the strength of the Tang Dynasty.

You must know that there are still so many alien races around, none of them have been cleaned, and there is another civilization that is connected to the land.

It is not necessary to use the method of HNA, but the premise is that Datang is strong enough.

"HNA can not be abandoned, although the shipbuilding technology can only expect luck, but if the Tang Dynasty craftsmen are gathered, it can not be further."

And Shu An seemed to see the thoughts of this emperor, and a faint voice sounded.

In his opinion, the craftsmen of this era have good potential, as long as they are given enough knowledge, it may be possible.

This time, Li Shimin nodded, indicating that he had memorized it, and now this emperor did not dare to delay the words of this father.

"I hope that one day Datang will also be able to become an empire on which the sun never sets."

Shu An's eyes couldn't help but show a hint of hope and said, although this goal is a little far away, and it is even unlikely.

But it can be regarded as a hope, if Li Shimin can establish such an empire, then the tragedy of later generations will almost be changed.

If you come into contact with the whole world a thousand years in advance, you don't know how wonderful the world will be in the future.

"What does the sun never set?!"

Li Shimin, who was on the side, heard his father's words and couldn't help asking.

Shu An's eyes flickered, and when it came to the fact that the sun never set, there was some trouble, after all, it was first necessary to make sure that the earth was round.

Even if it is explained, it will take a long time to explain, but since Li Shimin wants to know, Shu An doesn't mind explaining.

"First of all, let's explain, let's talk about the problem of the continent under our feet."

"The people of the world have ever thought about the fact that the ship on the shore always disappears first, and the mast disappears after and stands tall so that you can see far."

.......

Shu An's words kept ringing, and even Li Xiuning couldn't help but listen.

Because they have never been exposed to this knowledge, it can be said that these problems are often not paid attention to.

But it was just a topic, and from daytime to dusk, this emperor only had some understanding.

"Your Majesty, it's time to go back!"

Li Junxian couldn't help but smile bitterly and said aloud, although he was embarrassed to disturb His Majesty's Yaxing.

But it was obviously time to return to the palace, but this emperor still had an inquiring gaze on his face.

"I won't go back tonight, I want to have a long talk with my father!"

Li Shimin's voice sounded, and there seemed to be a trace of excitement hidden in his words, which was a desire for truth.

Even Shu An, who was on the side, couldn't help but secretly sigh in his heart, with Li Shimin's knowledge-seeking attitude, being an emperor was really wronged.

However, if Li Shimin wants to understand, Shu An will naturally not refuse.

For a long time, he did not bring some of the knowledge of later generations to this era, but now is the time to say.

First of all, the first step is to start with this emperor, although let Li Shimin understand that the earth is round.

But to explain why one can stand on top of the question, it can be said that one question leads to another.

In this way, Li Shimin is naturally becoming more and more energetic, after all, he has encountered something that has changed his cognition.

It wasn't until the morning light rose again that the emperor reluctantly left.

"Emperor Xuan of the Han Dynasty Dinghu inscription, once said that the sun and the moon shine, the wind and rain come, do not obey."

"But now it seems that there is a well watching the sky, and the sun and the moon shine far more than that."

Li Shimin's eyes flickered and he couldn't help muttering, obviously interested in this empire where the sun never sets.

However, he also knew that the road still had to be walked step by step, and when he went back, he would start to analyze it from the surrounding area.

Let's see which side Datang is most suitable for development, or expand in all aspects, and the other thing is that HNA can't relax.

It's not just the words of the father, but the benefits brought by HNA itself are something that this emperor cannot ignore.

"Finally gone!"

Looking at Li Shimin's departing figure, Shu An couldn't help but rub his eyes and said softly.

You must know that he has never stayed up late for a long time, not to mention that this emperor and Li Xiuning have the spirit, but he doesn't.

In order to live a few more years for himself, Shu An did not hesitate to rest.
