Listening to Li Su's words, Li Shimin couldn't help but sigh and said: "Su'er, your thinking is good, but in fact, you can't do it at all!" ”

Li Su's insight certainly amazed Li Shimin.

Well, in fact, what Li Shimin doesn't know is.

Li Su's insight comes from the prophets of later generations.

Because in the original historical trajectory, all kinds of things predicted by Li Su really happened.

However, Li Su's idea of solving the problem made Li Shimin slightly disappointed.

But soon, Li Shimin laughed dumbly.

Su'er is just eleven years old this year, and she is still a child.

Do I expect too much from him?

In fact, even the current Li Chengqian and Li Tai may not be able to do it to the point of being so stunned!

Thinking of this, Li Shimin couldn't help but patiently explain: "Su'er, the emperors of all dynasties, don't you understand this truth? But why has no one ever done that? Is it because all people are powerless? ”

"In fact, it's not. Emperor Qin swallowed the eight wildernesses, and Han Wu was eloquent, couldn't they do this? It's not that you can't, but you can't! ”

"Because the land of Tubo and Nanzhao is a barbarian land, even if it is fought down for a while, it is difficult to educate because of the inconvenient transportation, and it is difficult to carry out actual control for a long time."

"Over time, they will inevitably rebel against independence again. The effort is grossly disproportionate to the gain. Therefore, the emperors of all dynasties have dealt with the frontier problems by means of suppression, tenderness, co-optation, support, separation, and marriage. Do you understand? ”

Li Shimin naturally understands the problem he said.

However, Li Su has a solution to the problem.

Li Su couldn't help but say: "Father, what if we can produce a means of transportation that can achieve rapid passage between the two places?" For example, a land of thousands of miles can be reached in just one day? ”

Hearing Li Su's words, Li Shimin's eyes suddenly became bright and scary.

Is there really a vehicle like the one that Yu'er said?

If such a means of transportation were to exist, then geographical remoteness would not be an issue.

The southwest issue can be solved.

Li Shimin couldn't help but ask in surprise: "Su'er, can the kind of transportation you said really be manufactured?" ”

Li Su nodded and said, "Father, the son expects that it will probably be made within a year!" ”

After listening to Li Su's words, Li Shimin couldn't help but fall into deep thought.

After a while, Li Shimin couldn't help but look at Li Su with burning eyes and asked, "Su'er, if my father hands over the southwest to you, do you have the confidence to give me a peaceful southwest?" ”

At the beginning of the founding of the Tang Dynasty, relations with the frontier were extremely tense.

The southwestern frontier, the northwest, the northeast, friction is constant.

And Datang's current national strength is not enough to support multilateral wars.

If Li Su can sit in the southwest and pacify the southwest, it will greatly reduce the pressure on the border of the Tang Dynasty.

Under Li Shimin's expectant gaze, Li Su nodded and said, "The son will definitely live up to his father's trust!" ”

"Good!"

……

Chang'an City, since the departure of Li Su, the king of Shu, seems to have lost most of its vitality at once.

When the King of Shu was there, he first started with the Zhenguan table and Zhenguan chair, and then monosodium glutamate, the first floor in the world, the first courtyard in the world, as well as ice cream, opera and so on.

A king of Shu has prospered a Chang'an city.

And after the king of Shu left, there seemed to be nothing new in the entire Chang'an City.

What is popular in Chang'an City now is the rest of what the King of Shu played at the beginning.

Even those operas, after the king of Shu left, showed a state of decline.

Even if the new drama is launched, it is old wine in new bottles, and it is lackluster.

Many merchants in Chang'an City are looking forward to the return of the King of Shu again.

And this time, the people and businessmen in Chang'an City suddenly found that there have been lively things in Chang'an City!

In the whole city of Chang'an City, there were suddenly more than a dozen strange things.

This thing is more than half a foot high, and when a person walks to the front, a living person can be reflected inside.

"Youkai!"

The first person to shine on it was horrified by the person who appeared in this strange thing.

I'm a Maya, where did this come from, such an ugly monster?

This person was so frightened that he ran away, and his pants were about to pee.

And it was far more than this one person who was scared.

On this day, in Chang'an City, I don't know how many people were so frightened by this strange thing that they ran away, and they didn't even know how many shoes they ran away.

Until they found out, it seems that as long as you don't get close, there will be no monsters in this strange thing.

The monster inside this strange thing doesn't seem to be able to get out.

It was this discovery that made people gradually calm down.

And it wasn't until noon that someone speculated that these strange things, could it be, turned out to be mirrors?

When the Tang Dynasty was in power, it was still a bronze mirror.

Grind a piece of copper to be smooth and recognizable, and a human figure can be vaguely reflected on it.

It's just that the clarity can't be seen at all.

Could it be that these strange things erected are really mirrors?

But how can it be so clear?

What is this mirror made of?

It's really, amazingly!

Then, the people in Chang'an City soon discovered a problem.

The place where these mirrors are erected is the first floor of the world's industry.

In other words, they are all the property of the King of Shu.

This novel mirror was also made by the King of Shu.

No wonder!

In fact, the King of Shu has created too many miracles.

If this mirror was created by the King of Shu, it would definitely not be surprising.

After discovering this new thing, which is actually a mirror, countless people feel sorry for themselves in front of the mirror.

This mirror is really amazing, it is actually delicate, even a few hairs, it is clearly illuminated.

It would be great if I could have such a mirror in my home and be able to shine it every day!

Countless people can only think about it in their hearts.

Those people, many people, can't even afford to buy a bronze mirror at home.

Not to mention, it's like such a magical mirror.

Such a magical mirror, the price, I'm afraid it's not a sky-high price?

Such a price is simply not what they can afford.

However, those wealthy families, after seeing this magical mirror, have moved their minds.

Especially those ladies and ladies, after seeing such a magical mirror, they couldn't move, and they couldn't wait to move back to their homes immediately.

They sent people to inquire, how much do these mirrors cost?

For example, those young ladies of the family with five surnames and seven wangs have even made plans, no matter what the price is, they must buy them home.

Because they buy things, they basically don't have the habit of looking at the price.

Yanyu said lightly
