This was not an idea that suddenly occurred to Wang Buxu.

I have had the idea of ​​building a military fort for a long time, but I have never thought of building it at this stage.

The previous consideration was to maintain the rule of the grasslands by building military forts after defeating the Huns, and gradually assimilate them and swallow them up.

First use military forts to spread out and control each area.

Find a suitable place to build a city and let the nomads settle down.

There are many places on the grassland that are not suitable for farming.

But with all calculations, the entire grassland only has a population of two to three million.

The area in the north is larger than that of the Han Dynasty. Isn't it possible to find a land the size of Yingchuan County to accommodate them?

Innocent!

too naive!

Wang Buxu already had a way to deal with the grassland, but now he used it in advance.

"Since we're going to do it, let's do it bigger!" Wang Buxu looked at everyone and said directly.

"Bigger?"

Chen Ping, Xiao He wished he could give himself a slap in the face in front of everyone, and say nothing about the Great Wall in a cowardly manner?

Well, now that the emperor has taken over, this bitch is just shooting herself in the foot.

"Yes, I will make it impossible for the cavalry on the grassland to hide!" Wang Buxu said fiercely.

The most annoying thing about farming civilization is the cavalry troops that come and go without a trace.

But if the enemy can be found hundreds of miles away, and the news can be sent back to the level in time.

So, can the nomads still break through the defense line?

The answer is obvious, no.

The cavalry's siege ability was almost zero. Every time they broke through the defense line and went south, it was because of a successful raid.

As long as the defenders are well prepared, even if they reach the checkpoint, they will be powerless.

The height of the Great Wall is between six and seven meters. Even if it is built on flat land, it is an insurmountable barrier for cavalry.

"I want to build a military fort on the grassland!"

"Fort?"

"Yes, military fortress!" Wang Buxu nodded and continued: "The military fortress is just a nail stuck in the grassland by the big man. There is no need to arrange too many personnel. A small fort five miles away can be built for one thousand and twenty.

If you have a middle fort within a mile, you can build a village; if you have a small fort within fifty miles, you can build a village with five hundred!"

"The small fort is a hundred steps long and wide, with a wall three feet high, and is equipped with beacons. The middle fort is three hundred steps long and wide, and the big fort is a thousand steps long and wide. It is responsible for guarding in peacetime, and can be used as a post station in wartime, and even provides protection for the army!"

"Your Majesty, this... seems a bit unrealistic..." Xiao He hesitated, how much would such a large project cost...

"Why is it unrealistic?" Wang Buxuan glared at Xiao He. It was indeed unrealistic before.

Because the construction speed of military forts with rammed earth structure is too slow, each one consumes a lot of manpower and energy.

But it is no longer necessary. Brick structures can be constructed quickly and can be operated in terms of cold resistance.

"Three bricks laid flat are just one step, and a hundred steps is only three hundred bricks. One and a half steps wide is enough, and eight bricks are enough. A brick is one foot high, and these three feet are only forty-five bricks.

Bricks are enough. More than 30,000 bricks are enough for the four city walls. Small bricks can be used for the buildings inside. It only costs 40,000 to 50,000 bricks. The bricks produced by Luoyang Brick Factory can build three such buildings in one day.

What's so difficult about building a military fort? When the time comes, the military fort will be located in a place where a well can be dug. One person will only consume thirty-six shi of grain and grass per year. Each small fort will be equipped with 500 shi of grain and raise a group of sheep.

The Huns could not do anything to them even if they surrounded them for a year!" Wang Buxu decided to let data speak for himself.

This is more reliable.

Although depending on the layout mode, the required materials will be different.

And when the city wall was built, it didn't mean that everything inside was made of pure bricks.

Bricks in the Han Dynasty were divided into two types, large bricks and small bricks.

The standard for large bricks is about two feet and forty-six centimeters long, and one foot and twenty-three centimeters in width and height.

The combined width of the two blocks is just equal to the length of one brick, which facilitates cross-layout during construction to achieve a more stable purpose.

This type of brick is too large in size, not light in weight, and takes longer to bake. However, precisely because of this characteristic, it is only used to build defensive fortifications such as city walls.

Small bricks are used in building houses, and are three times smaller in length, width and height than large bricks. They are lighter in weight and more convenient and flexible to use.

For such a military fortress, even if it was only staffed by ten people, the Huns would not be able to handle it even if a hundred of them came.

The cavalryman who even had a headache when encountering a city wall that was two battles high could not move forward. Now he encountered a military fort that was three feet high. What could he do?

Grain, plus sheep, can be eaten sparingly to last for a year and a half.

Coupled with the well, this is even more comfortable and can directly and effectively prevent the other party from contaminating the water source to achieve their purpose of capture.

"Don't underestimate these military forts. As long as they can be built and erected one by one on the grassland, they will be like hedgehogs. If the Huns don't want to be monitored by us, they will either attack or go elsewhere."

Here, Wang Buxian walked back and forth with a slight smile on his face:

"To attack, the Han army knew their movements hundreds of miles away and had already made arrangements to capture the military forts. This was even more impossible. Hundreds of military forts stood there and attacked one by one.

, it can’t be done within a few years.”

"And if they leave, won't the big man have another pasture to train his war horses?"

"Good! Great good! Your Majesty's move is really wise!" Chen Ping's eyes suddenly lit up.

Although the Han Dynasty extorted 250,000 war horses from the Yuezhi people, they also captured 90,000 more.

But this quantity is still not enough, and you can't expect to capture or extort war horses forever.

If the Han cavalry wants to truly take off, they must have their own horse farms. One horse farm is not enough.

Raising horses in the eastern grasslands is very necessary.

An excellent war horse does not mean that you can run fast or be strong.

But one thing is that excellent war horses all come from plateau and alpine areas.

This is the reason why Emperor Wu of the Han Dynasty's private horse breeding policy failed in history. The climate was not good, and the war horses raised were not up to standard.

It’s the same feeling as a person from the plains going to the plateau for the first time.

People can persist and adapt to it for a while, but war horses can't. These things are very delicate, and they are the kind that will be broken into pieces when they die.

And similarly, it was only at this time that these people realized the functions of the military fort.

Not only can it be used for early warning, driving, and enclosure, but it can also be used to protect the pastoral areas in the rear.

Therefore, to use a fashionable saying, building these military forts is a project of strategic significance.

"Your Majesty, the scale of the military fort can be smaller. How can ten people use a place that is a hundred steps long and wide? And it is too big and is not conducive to defense. There is no way to escape. There will be no way for two people to guard a wall.

Right? Thirty steps is enough!" Xiao He began to calculate again.

Then he spread his hands, ten people really can't use such a big place...

To convert again, one step is six feet, one foot is 23.1 centimeters, and one step is equal to 1.38 meters.

Of course, the steps of the ancients refer to compound steps, that is, each step of the left and right feet is counted as one step. After all, a person is a whole body, and there is no way to separate it and count it.

Therefore, even if it is thirty steps, it is still 41 meters long and wide. In this case, two people face a wall, stand 20 meters apart in the middle, and each is responsible for 10 meters on the left and 40 meters. Perfect!

The most important thing is that the materials used to build one military fort can now be used to build three.

"For some things, bigger is not always better. Even if you build a small fort with a hundred steps, how many troops can be packed in this size? Is there any difference between fifty people and ten people? Anyway, when the enemy comes, they are all

It’s not necessary to stay tight and defensive, isn’t it?”
