Second short video, the world was confused after watching it

No solution!

Li Shimin's eyes widened, and the words staring at the sky continued to emerge.

[Throughout the ancient and modern times, what hindered the expansion of the territory of ancient dynasties was capacity, message transmission, and cultural dissemination. 】

[In ancient times, the transportation capacity was low, and in addition to the grain and grass for the soldiers, there would be great consumption in transportation. 】

[Moreover, for every hundred miles of transportation distance, the less grain and grass can be transported to the destination. 】

[It is precisely because of the lack of control that the local Confucian cultural identity is relatively low. 】

[In ancient times, powerful empires would govern the local area in a form similar to colonization. 】

[While obtaining economic benefits to feed itself, it can also assimilate the local area by adjusting the people to the border. 】

[Undoubtedly, this is the way to maximize benefits.] 】

[However, this method of management cannot control the local warlord group.] 】

[Once the central control is weakened, the local economy will become stronger with local development. 】

[In the case of insufficient cultural identity, the local area will naturally form a warlord monopoly on the local area, and support the army for its own respect. 】

[This kind of problem is not only in ancient times in the world, but also in modern history, it is also a problem that has plagued the West for a long time. 】

[Even the best belt with a balanced hand and his own son were burned in the end. 】

[Of course, if according to the subject's idea, you yourself are Li Shimin, these questions will naturally not be a problem. 】

[But in the future, as long as the emperor is incompetent, an existence like An Lushan will grow at any time. 】

...

After reading the answer, Li Shimin's face had become a little ugly.

"It took me a day. "

"I found so many people to come to worship the heavens. "

"That's all I could get?"

At this time, the group of ministers behind him, who also saw the answer from heaven, became more and more agitated.

"Your Majesty has spent so much effort just to get an unsolvable answer?".

"Your Majesty, this is a waste of luxury. "

"Your Majesty, has you forgotten Emperor Yang of Sui in the previous dynasty?"

Li Shimin was a little embarrassed by everyone's spray.

It's also a little unbearable on the face.

I just couldn't find any excuse to refute it.

I was just thinking about what to say.

Li Shimin suddenly discovered.

The words on the canopy don't end.

Strengthening cultural identity does not happen overnight. 】

[However, there are ways to quickly enrich the country and strengthen the people. 】

Subsequently, a variety of crops that are convenient to grow such as potatoes, but there is no seed introduction in China for the time being, and the closest production areas to the current Datang were listed.

Seeing this, Li Shimin's expression moved.

The resentment in my heart also dissipated a lot at once.

"It says that there is a tuber called a potato, which not only produces more than grain. "

"And it can be grown on barren land?".

"And this corn, which is also very productive. "

"And when it dries, it's easy to store..."

"But these places are too far away. "

"It's hard to save thirst from far water. "

Li Shimin's thoughts had not yet dissipated, and the sky seemed to have sensed it.

In the next moment, new words appeared.

[Greenhouse construction method. 】

Li Shimin looked at it very seriously and muttered in his mouth.

"If this greenhouse is successfully built, there will be a harvest in winter?"

"It's just that where can I get the plastic described in this greenhouse?"

As soon as the words fell, new words appeared above the canopy.

[Colorless glass preparation method. 】

The text appears with a parenthesis at the end.

"It can be used for sunlight harvesting instead of plastic. "

"You have to keep extra warm on top at night. "

Finally, there is a large paragraph of text.

Looking at the string of words flickering in front of him, Li Shimin's eyes were straight, and he was a little incredulous.

Although at this time, the content displayed on the canopy has not been experimented.

But as an emperor, Li Shimin can already realize a very terrible thing from a macro level.

"If you can find the seeds of those high-yielding crops. "

"Then, a lot of wasteland that was not used before can be put into use at this time. "

"As for the construction of greenhouses, you need to use glass..."

"It's expensive, but it can be set up in a northern fortified city. "

"That way, we don't have to worry about running out of supplies, even in winter. "

"The greenhouse must be able to replenish some of the food supply. "

"It's not all... If all kinds of crops are ripe in the summer, they can be planted in the greenhouse. "

I want to come to the rich businessmen and gentry in winter.

Even the king of the northern kingdom will inevitably choose to buy it at a high price.

By that time, it was another batch of receipts.

"As long as the treasury is full, all the crises I am in now will be solved!"

"Not only that, but if we can increase production, even in a famine year, we don't have to worry about not being able to provide relief to the victims!"

Thinking of this, Li Shimin could no longer hide his emotions.

Grinned, revealing eight teeth.

Turning his head, he looked at the ministers behind him who were staring at the sky with dazed expressions.

Li Shimin spoke slowly.

"Ladies and gentlemen, you seem to think that this canopy is useless?"

As soon as the words fell, everyone suddenly came back to their senses.

The slap in the face came too quickly.

The crowd was a little overwhelmed.
