In the apartment next door.

Lin Che slowly drank the warm daughter red, and asked Zhu Bai, who was frowning, "Have you figured out the answer to the question just now?" ”

After all, Zhu Bai is too young to even read a few history books.

Where can you come up with an answer to such an esoteric question.

After thinking about it for a long time, he couldn't figure it out, so he could only bow his head in shame and say, "The student is stupid, and he hasn't come up with an answer yet, so please ask Mr. to teach me." ”

Lin Che's answer to Zhu Bai's raising of the white flag was also expected.

He nodded, and then tilted his head to look at Zhu Gui: "Do you know? ”

Originally, Lin Che didn't have any hope for Zhu Gui, who came to listen to the class for the first time, just a habitual question.

Unexpectedly, Zhu Gui nodded and replied: "Sir, the students feel that many Han dynasties are orthodox, and their footsteps are limited to the homeland of the Han and Tang Dynasties, and the biggest reason is food. ”

"Let's not talk about it far away, let's just say that now the grain and grass on the nine sides have to be sold for salt, so that the salt merchants can transport the grain to the frontier."

"One of the biggest reasons is that there is no way to grow food in the bitter cold of the nine sides, which also blocks the pace of expanding the territory."

Zhu Gui is older than Zhu Bai.

It was based on the books I had read in the past, and the words about the war that I occasionally heard in the university hall.

Pieced together a seemingly correct answer.

"Yes, your kid has a wide vision, and he can actually think of this."

Lin Che glanced at Zhu Gui in surprise.

He thought that Zhu Gui, who came here for the first time to listen to the class, was here to make soy sauce.

I didn't expect this kid to be able to consider the issue of grain and grass in such a short period of time.

Lin Che nodded: "The grain and grass have indeed decided, how far the imperial army can fight outside, and it also determines the size of my Ming territory in a certain way." ”

"However, the most fundamental reason is actually the road, to be precise, the traffic problem."

Zhu Gui didn't expect that he had come up with the answer, but he actually got Lin Che's approval and praise.

Originally, he was just playing with Zhu Bai, but he suddenly became interested in listening to the class.

Hurriedly asked: "Sir, why is the expansion of the empire still related to transportation?" ”

In Zhu Gui's view, fighting a war is enough to have strong soldiers and horses, well-armed weapons and armor, and sufficient food and grass.

No matter how you count it, it has nothing to do with walking.

"There's a theory called the limit of empire rule."

Lin Che dipped his hand in some wine and drew a map of the territory of the Ming Dynasty on the table.

Then marked the location of Ying Tian: "It is usually said that you want to really bring a place under the control of the imperial court. ”

"The soldiers and horses of the imperial court must be able to reach this place within a month.

Lin Che said, and on the simple map drawn with wine, he pulled out a horizontal line from Yingtian to the north.

smiled: "It's like, starting from Yingtian and going to Shanhaiguan, it has just been twenty-nine days." ”

"Therefore, the land in the Guannai can be firmly controlled by the imperial court."

"On the contrary, the Mobei grassland, from ancient times to the present, I don't know how many times it has been subdued."

"But the elite division of the imperial court walked to their hinterland within a month, so there is always a situation of surrender and rebellion."

Zhu Bai, who had been thinking about it for a long time just now and didn't come up with a clue, heard this novel theory.

Suddenly, his eyes lit up and he said, "Sir, I understand what you mean." ”

"You mean that as long as I am very elite, I can reach the place within a month."

"Here you will obey the laws of the imperial court, pay your taxes on time, and obey your labor."

"And the places outside the scope of this month are basically self-governing by the locals."

"Not only will they not pay taxes, but the court will also have to reward them regularly, just ask them not to rebel and make trouble?"

It's a very simple account.

For example, today, it should be said that the richest place in the whole world.

It's now the Great Tomorrow Dynasty.

And the nearby horns and corners all belong to the existence of poor slag.

If not, the expansion of territory has been a supreme achievement since ancient times.

I'm afraid that there will never be an emperor who will fight such a money-losing battle.

But this kind of battle is basically fought once at the time of the founding of the country.

If you fight again, the court will not be able to afford to lose.

Therefore, it is better to give rewards and appeasement than to rebel in these places that are outside the military deterrence of the imperial court.

Because once the imperial army marches away, it will take more than a month.

If you lose, you won't lose, the main thing is that military spending will soar.

Coupled with the resentment of the soldiers who have been rushing for a long time, it will inevitably strangle the rebels on the border.

It would be difficult not to hurt the innocent, and it would make it even more difficult for the imperial court to control the place.

"What you said is very right, whether it is outside the customs or southern Xinjiang, it belongs to the bitter cold land."

"The money and grain that the court spent on beating them once, if they continue according to the reward, they will not be able to be paid out in a hundred years."

Lin Che praised a few words, Zhu Bai's ability to associate well.

Then, on the simple map, some curves were drawn instead of rivers: "When the army is on an expedition, it is good to say that the place where the boat can be passed, even if the boat ride is longer, the soldiers will not be very tired, and the consumption of grain and grass will not be very large." ”

"But if you take the land route alone, not only will the speed of the soldiers gradually decrease."

"In the area of more than a month, ten stones of grain and grass were transported, and the people who transported it had to eat ninety percent of it."

When the Central Plains Dynasty opened up outside the Han Dynasty.

The biggest worry has never been whether or not you can beat the enemy.

It's about how far the rations can be delivered.

However, because of the extremely poor transportation conditions in ancient times, the consumption of grain transportation was extremely large.

Very often, the Cypriot territory is beaten down.

Eventually, they will have to spit out these lands due to the loss of grain and grass transportation.

Zhu Gui, who began to listen carefully to the class, enjoyed the feeling of talking on paper.

The problem of grain and grass consumption in the place where Lin Che died directly made him dumbfounded.

couldn't help but exclaim: "Sir, according to what you mean, isn't it that I'm a Ming Dynasty, and I can only be confined to the traditional Han land like many previous dynasties?" ”

If that's the case, then Daming is still a big Mobei.

What is the way to explore the Wa Kingdom?

Just retract back to your homeland and play defensive counterattacks.

The saved military spending can also make the people's lives a little better.

"Hahaha, if you've seen the maps of all dynasties."

"It should be clear that the so-called Han land is actually different in every era."

Lin Che was amused by Zhu Bai's words.

He took out a few pieces of paper, and the dragon flew and the phoenix danced on it, outlining the map.

Then he spread it flat on the table, and explained in contrast: "You can see that during the Han Dynasty, although the south also belonged to the rule of the Han family, "

"But these places have not been developed, and the number of Hermes-Epitek is not very large, so it can only be regarded as a place of fetters."

"And after the Jin Dynasty's clothing and southward crossing, coupled with the development of the Tang Dynasty, and the Great Song Dynasty is inevitable."

"The south has been greatly developed and has become a real grain tax area, which has been completely pinched in the hands of the Central Plains Dynasty!"
