This is not a sudden thought that Wang Bu is hungry.

I have had an idea of building a military fort for a long time, but I haven't thought about building it at this stage.

The previous consideration was that after defeating the Xiongnu, he would build a military fortress to maintain the rule of the steppe, and gradually assimilate them and swallow them.

First use the military fort to disperse and control the various areas.

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

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

But when it is all counted, the entire grassland has a population of only two or three million.

The area in the north is larger than that of the Han Dynasty, so can't they find a land the size of Yingchuan County to house them?

Naive!

How naïve!

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

"Since you want to do it, let's do it bigger!" Wang Bu looked at everyone and said directly.

"Bigger?"

Why can't Chen Pingxiao slap himself in front of everyone, what is there to say about the Great Wall?

Now that the emperor is on top, this damn thing is simply lifting a stone to shoot herself in the foot.

"Yes, I want to make the cavalry on the steppe unremarkable!" Wang Bu was hungry and said viciously.

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

But if you can spot the enemy hundreds of miles away, and send the news back to the level in time.

So, can the nomads still break through the defenses?

The answer is obviously, no.

The cavalry units had almost zero siege capability, and every time they broke through the defensive line and headed south, it was because of a successful raid.

But as long as the defenders are well prepared, even if they get to the level, they can't do anything.

The height of the Great Wall was between six and seven meters, and even if it was built on flat ground, it was an impenetrable barrier for cavalry.

"I'm going to build a military fort on the grassland!"

"Fort?"

"Yes, Fort!" Wang Bu nodded and continued: "The military fort is a nail inserted by the Han on the grassland, and there is no need to arrange too many personnel, a small fort in five miles, a medium fort in twenty miles, a tun, a big fort in fifty miles, and five hundred!" ”

"The small fort is 100 steps long and wide, the wall is three zhang high, and the beacon is placed, the middle fort is 300 steps long and wide, and the big fort is 1,000 steps long and wide, and it is responsible for guarding in peacetime, and can be used as a post station in wartime, and even provide security for the army!"

"Your Majesty, this ...... It seems a little unrealistic...... "Xiao He hesitated a little, how much should it cost for such a big project......

"How is it unrealistic?" Wang Bu stared at Xiao He, it was indeed unrealistic before.

Because the construction speed of rammed earth forts is too slow, each of them requires a lot of manpower and energy.

But now it is not needed, the brick structure is built very quickly, and it can be operated in terms of cold resistance.

"Three bricks are laid flat in one step, a hundred steps are only three hundred bricks, one and a half steps wide is enough, and eight bricks are enough. A brick is one foot high, these three zhang is only forty-five bricks are enough, four city walls, more than 30,000 pieces are almost, the buildings inside can use small bricks, all down to 40,000 or 50,000 bricks, Luoyang brick factory can build three such military forts in a day, what is the difficulty? At that time, the military fort was selected in a place where the well could be dug, and one person could only consume 36 stone of grain and grass a year, and each small fort was equipped with 500 stone of grain, and a group of sheep were raised, and the Huns could not help them even if they surrounded them for a year! "Wang Buxing decided to use data to speak.

It's a bit more reliable this way.

Although depending on the layout mode, the materials required will not be the same.

And when the city wall was built, it didn't mean that it was all pure bricks.

The bricks of 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 the width and height are about one foot and twenty-three centimeters.

The width of the two pieces can be just the same as the length of a brick, so that it is easy to cross the layout when building, so as to achieve a more stable purpose.

Because of its large size and weight, it takes longer to fire, but it is precisely because of this characteristic that it is only used for defensive fortifications such as castle walls.

The small bricks used to build the house are three times smaller in length, width and height than the large bricks, the weight is lighter, and it is more convenient and flexible to use.

Such a military fort, even if it is only composed of ten people, the Huns will not be able to handle it even if they come to a hundred.

The cavalry who couldn't even walk when he had a headache when he met two battles of high walls, and now he met a three-zhang high military fort, what could he do?

Grain, plus sheep, is enough to last a year and a half.

Coupled with the well, this is more comfortable, which can directly and effectively prevent the other party from polluting the water source to achieve the purpose of attack.

"Don't underestimate these military forts, as long as they can be built and set up on the grassland one by one, they will be like hedgehogs, if the Huns don't want to be watched by us, they will either attack or go somewhere else." Speaking of this, Wang Buxing paced back and forth with a slight smile on his face:

"Come to attack, the Han army has known their movements hundreds of miles away, and has already made arrangements to capture the military forts, which is even more impossible, hundreds of military forts are standing there, attacking one by one, it is impossible to do it in a few years."

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

"Good! Great goodness! 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 Yueshi people, it seized another 90,000.

But this is still not enough, and you can't count on capture or extortion forever.

If the cavalry of the Han Dynasty wants to really take off, they must have their own horse farm, and one is far from enough.

And in the eastern steppes, it is necessary to raise horses.

An excellent war horse does not mean that you can run fast and grow strong.

But there is one point, excellent war horses, all from the plateau, alpine region.

This is also the reason for the failure of Emperor Wu of the Han Dynasty's private horse breeding policy in history, the climate is not good, and the war horses raised are not up to standard.

It's the same feeling as when someone from a plain area goes to the plateau for the first time.

People can still hold on to adapt to a while, but not war horses, this thing is very delicate, and when you die, it is a large piece.

And in the same way, it was only at this time that these people reacted to these effects of the military fort.

It can not only be used for early warning, drive, enclosure, but also to protect the pastoral areas in the rear.

So, to use a fashionable phrase, the construction of these 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 with a length of 100 steps? And it's too big to be defensive, and you can't run away at all, so you can't have two people guarding the same wall at that time, right? Thirty steps is enough! Xiao He began to calculate again.

Then spread your hands, ten people really don't need such a big place......

To convert it 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 the double step, that is, the left and right feet each step is counted as a step, after all, people are a whole, how can there be a disassembly.

Therefore, even if it is thirty steps, it is also a place of forty-one meters in length and width, in this case, two people are on the same wall, standing in the middle of the twenty meters apart, the left and right sides are responsible for ten meters, forty meters to get it, perfect!

The most important thing is that the materials of the original one military fort can now be built into three.

"Some things are not always better if they are bigger, even if a small fort of 100 steps is built, how many troops can be loaded into this size? Is there any difference between fifty and ten? Anyway, when the enemy comes, you have to shrink back and defend, so there's no need for this, is it? ”

Wang Buxing pointed at Xiao He speechlessly, and said, "You are really the first master of the Han ......."
