For the Americas, since Li Ke is ready to say it, then he has already thought about the follow-up, at least when he is alive, although he is not the emperor, but his influence on the entire Tang Dynasty is definitely beyond doubt.

When the time comes, he will frantically put pressure on the courtiers in the back, so that they will have a deep impression of a powerful enemy in their minds.

Then after Li Ke died, it didn't matter how the follow-up Datang would develop Li Ke, anyway, at that time, Li Ke didn't know how much territory Datang could build, but they always had a powerful enemy as an imagination and as an alert.

When Li Ke dies, it is estimated that the next prince of the eldest brother should also be arranged by Li Ke, as long as there is no problem with his thinking, then Datang will definitely still be crazy about developing science and technology, and there will be no problems.

After Li Ke's death for more than ten years, or decades, Datang's science and technology have developed to a certain extent, maybe when the Tang court at that time felt that Datang had no way to carry out high-speed development, they might try to let the fleet take the step of exploration.

When the time comes, let the Tang fleet at that time face the "powerful" Indians! When the time comes, whether it is the "powerful" Indians or the powerful "Mayan civilization", it will definitely give these fleets of the Tang Dynasty a huge surprise.

Anyway, at that time, Li Ke was long gone, and he couldn't see it, even if it was a small joke for future generations?

Well, it's kind of interesting to think about that kind of scene.

After all, if you are gone, it should be very interesting to make a joke to your children and grandchildren so that they can remember their ancestors.

As for how to deal with that continent, Li Ke didn't bother to take care of it, how could he manage everything, just live happily in this life.

Li Ke's mind was full of all kinds of thoughts, but these people at the military headquarters meeting were stunned, they had always thought that His Highness was a worldly talent, but now His Highness told them that the advanced technology in his hands also came from the other half of the powerful empire in this world.

Even one day, the other party may come directly across the sea on a huge sea boat, how can Datang resist at that time?

"Now you understand why I'm always feeling anxious? It's not that I forced you to work, in fact, Datang can be slower, nothing. But since we have the power, we cannot allow our people to be invaded again. ”

"Every time there is a change of dynasty, it is the people who suffer, tens of millions of people at the peak of the Han Dynasty, but what about the population of the Tang Dynasty now? According to a survey on household registration management submitted by the Ministry of Public Security this year, the total number of households in Datang is only 7.6 million, with an average household size of about 5 people and a total population of 38 million. Li Ke looked at them and said.

The population of the Tang Dynasty must be stronger than that of the same period in history, at least because of Li Ke's existence, there are too many hidden populations and other territories in the entire Tang Dynasty to join the Tang Dynasty, and hundreds of thousands of people in Tuyuhun, including the various frontiers of the Tang Dynasty, have been fleeing in one after another to become the people of the Tang Dynasty.

In addition, Lingnan Road, Jiannan Road, Jiangnan Province and other places with 100,000 mountains, because of Li Ke's policy, more and more people of Shanyue registered and then integrated into the Tang Dynasty and became the people of the Tang Dynasty, and then the popularization of the "Barefoot Doctor's Manual" in the past two years has caused a wave of baby booms in Datang.

The combination of these various reasons made the population of Datang, which was about 3.5 million households in the early years of Zhenguan, skyrocket to 7.6 million.

But this population is too small for the current land area of Datang, with the current land area of Datang, I dare not say that it will feed 1.4 billion people like later generations, but there should be no problem in feeding 3400 million.

"The current population of Datang cannot reach the peak of the population of Dahan, but our land area is actually far greater than that of Dahan, and our land area will continue to expand in the future, and these land areas are our strategic depth, and can allow us to feed more people and mine more minerals." Li Ke looked at them and said.

"Your Highness, I can understand your concern, but now there is a problem." Li Jing, who was sitting next to him, hesitated and spoke.

"You say it." Li Ke said.

"That is, with the increase in the land area of Datang, our dependence on the local garrison will definitely increase, because it takes longer to transfer troops, so the local soldiers stationed in the local area will definitely be the trend in the future, after all, even if a soldier becomes a professional soldier, he must start a family."

"And the huge territory of the empire actually has a significant impact on the deployment of troops. This will also lead to insufficient control of the frontier by our imperial court. Li Jing is also much bolder now, and if he has something to say, he will say it directly.

"That's true, Your Highness, if it is not necessary, Your Majesty will not set up a capital protectorate in Khitan, Murowei and other places, and appoint these tribal leaders to become local capital protectors, that is to say, although these places are nominally part of my Tang territory, in fact they are basically equivalent to the vassal states of the Spring and Autumn Period and the Warring States Period. Our influence on them is only by force. Fang Xuanling pondered for a moment and then spoke.

The secret that Li Ke told was too scary, and these ministers had to face it squarely.

"I know, but my father is in good health now, and he will definitely have no problems in the next few decades, and in those decades, it will be time for us to develop new technology." Li Ke said in a serious tone.

"Huh?" Everyone looked at Li Ke with some doubts.

"I don't have a way to tell each other now, because the craftsmen have only put forward an idea, but many advanced tools come from imagination, maybe in ten years, we will have a new way of action, so that we can reach the countries of the Western Regions in seven or eight days." Li Ke said.

The emergence of the steam engine means that the train is not far away, even if it is an old-fashioned steam train, according to Li Ke's current industrial system, there is no problem in designing a train with a speed of 30-50 kilometers per hour, even if it is a speed of 30 kilometers per hour, the mileage can be driven in a day has reached a terrifying more than 700 kilometers, and ten days is more than 7,000 kilometers.

Even with a series of complex operations such as stopping and refilling water, ten days is enough to travel 5,000 kilometers.

5,000 kilometers, how far can Datang's territory expand? What's more, the strong transportation capacity brings more than just the dominance of the central court over various places.
