"Huh?"

Zhu Guizheng secretly laughed in his heart because of Zhu Bai's answer, which was denied by Lin Che.

He didn't expect that Lin Che would ask him, a newcomer, a question.

He didn't think about this question at all, so he could only subconsciously say nonsense: "Sir, the greatest benefit of the inland river master to my Ming Dynasty should be... It should be that the transmission speed is relatively fast.

This answer is not entirely nonsense.

Because the 800-mile rush is fast, but what is needed is to take a flat road.

Horses were changed along the way, and the messengers had to play relay races.

And not everyone can use it.

On the other hand, if the river flow is smooth, within a certain range, the speed of transmission is not much slower than that of the rapid.

But nowadays, another duty of the inland watermaster is to protect the safe and rapid transmission of the official documents of the Holy Decree.

It can be said that without them, the policies of the imperial court would be spread all over the land of China along the river.

Many new policies will have to be at least doubled in time for them to be implemented.

"You're right, the biggest benefit of inland waterways today is to ensure the smooth flow of information."

Lin Che smiled and praised the newcomer.

Then he looked at Zhu Bai, who was dazed but full of curiosity, and said with a smile: "Grain transportation is important. ”

"But if an empire doesn't even have a smooth flow of information, it must be a state of warlord secession."

If Zhu Fan were here, he would definitely be able to easily understand the importance of information being able to flow quickly.

It's a pity that these two little broken children, although they have their own cleverness.

However, due to the small number of lectures, the acceptance of some new concepts is too slow.

Lin Che thought about it and planned to change the way of teaching.

Then he asked with a smile: "Let's not talk about the issue of inland river sailors, have you ever thought that the dynasties of the empire since ancient times, after ruling the traditional Han land, are difficult to expand outward?" ”

The topic jumped from the sailor to the territory at once.

Zhu Bai was a little ignorant, he didn't have Zhu Zhang's military talent.

I couldn't figure out what Lin Che was going to talk about for a while.

I could only silently think about the questions he raised.

Zhu Gui, who was originally playing with Zhu Bai, saw that Zhu Bai looked dazed, for fear that he would be asked to give an answer later, so he also began to rack his brains to ponder the territorial issue raised by Lin Che.

In the secret room next door.

Zhu Yuanzhang did not study the territorial issues of previous dynasties.

Then he looked at Liu Sanwu and asked, "Liu Aiqing, do you know the reason for Mr. Lin's question?" ”

"Your Majesty, the minister thinks that the main reason is the food problem."

Although Liu Sanwu heard such a question for the first time.

But after years of experience in governance, he thought of the answer almost without thinking.

"Your Majesty, the traditional Han land in Mr. Lin's mouth is all cooked land that has been developed and can be cultivated."

"As long as there are people who farm, no matter how bad the land is, they can always produce some live food, but the situation can be controlled by the imperial court."

"Outside of the Han land, there are mostly rotten land that cannot be cultivated, and the people live by grazing, hunting, and chasing water and grass."

"If you live in a fixed place, you naturally can't set up prefectures and counties in the local area, and bring the local people under the control of the imperial court."

This point was also slightly mentioned by Lin Che when he gave a lecture before.

In short, the land carrying capacity of the grassland is not enough to support the grassland ethnic groups and implement settled life.

Even if the imperial court wants to collect taxes, I am afraid that the cost of finding people will exceed the taxes.

In the case of making ends meet, it is naturally impossible for the imperial court to make a loss-making deal and divide the rotten land within the territory.

Zhu Yuanzhang pondered for a moment, and couldn't help but nod and praise: "That's right, in the past Han and Tang dynasties, the grassland tribes were always like cutting leeks. ”

"Spend the money and food of the imperial court to exterminate one, and in a few years, a new big tribe will be born."

"Under such repetition, the Central Plains Dynasty has never had absolute control over the grassland, and the reason, as Aiqing said, is that there is no land to cultivate."

Speaking of this, Zhu Yuanzhang suddenly had an ambition.

He said proudly: "However, now there is Mr. Lin to give advice to Daming." ”

"We believe that whether it is the grassland or the territory outside the Han land, wherever I fight, I can take root there."

Before Lin Che appeared, Zhu Yuanzhang's greatest hope was nothing more than chasing the death to the north.

Completely strangle the remnants of the Northern Yuan.

Try to reduce the threat from the grasslands for future generations.

But after listening to Lin Che for so many lessons.

Zhu Yuanzhang's ambition has already risen, and it is no longer enough to conquer Mobei.

He wanted to completely incorporate the grassland into the territory of the Ming Dynasty.

In the future, it will also become the 'homeland of the Han land'.

Liu Sanwu also agreed: "Your Majesty is right, with Mr. Lin's guidance. ”

"As long as my Ming army does not rush into the expedition in the future, and wants to open up the territory, it is indeed much easier than the previous dynasty."

After learning of the existence of the 'Golden Mountain Silver Island' of the Japanese Kingdom.

Liu Sanwu heard Zhu Yuanzhang express his ambitions.

It's not like before, no matter what you shout about it, you don't have money.

Rather, it directly considers the cost of conquest, and how much it will ultimately cost to govern it to the level of Han land.

Zhu Yuanzhang pretended not to hear it, and Liu Sanwu advised him not to be happy.

Instead, he asked Zhu Biao, who was in charge of the records: "Boss, you have read a lot of history books, and you can know that many of the territories of the former dynasties, why were they finally limited to the Han land?" ”

It's a pity that Zhu Biao and Liu Sanwu also received Confucian education.

Even Lin Che's class was the same as listening, and it was difficult to give different answers.

He could only shake his head in shame: "Father, please forgive Erchen for being stupid, Erchen's answer is similar to that of Master Liu." ”

Zhu Yuanzhang obviously showed dissatisfaction with this answer.

But he didn't blame Zhu Biao for this.

After all, he himself has not come up with an answer until now.

I could only praise Liu Sanwu again: "Liu Aiqing, you can combine the theory of land carrying capacity with the expansion of territory." ”

"It seems that among the ministers, you are the one who really understands Mr. Lin's amazing learning!"

Liu Sanwu faced Zhu Yuanzhang's praise, but he lowered his head in shame: "Your Majesty, the old minister just made a little summary of what Mr. Lin said." ”

"Not only is it not proficient, but it is also possible that the answer just now is far from the correct answer to this question."

"The old minister is really shameless to accept it, Your Majesty praises it like this, Your Majesty, let's listen to Mr. Lin's lecture quietly."

Since the last time, Liu Sanwu guessed the answer to Lin Che's question, but he was too confident and was slapped in the face.

Liu Sanwu didn't think that his talent and intelligence could catch up with Lin Che's wisdom.

Zhu Yuanzhang was bored, so he didn't talk to Liu Sanwu again.

However, he had some expectations, in Lin Che's eyes, what was the reason why many of the territories of the previous dynasties were confined to the Han land?
