The Changshui School Guard Camp is not far from Zhangjia Manor.

Cross the Changshui River and walk more than 300 steps southward, you can see the solemn military camp.

Flags fly, battle flags fly.

As he rode his horse and walked under the village wall, Zhang Yue looked at the material of the village wall with great interest, and was amazed.

Because the wall of Changshui School Guard's camp is not the rammed earth wall as imagined.

Instead, it is mixed with mud, sand, reeds, straw, etc., and built with bamboo and wood as the skeleton.

Xu Xiangru watched from the side and saw Zhang Yue curious about the village wall, he explained: "Although the Changshui Captain has been stationed in the inner county all year round, he has to support the border after all the past years. However, the victory or defeat of the border war sometimes depends on the speed of building the wall..."

"Therefore, the six Northern Army captains, including the Changshui Captain, and other elite military camps and cities of the inner counties, were built by the method of building walls on the border, and they were replaced every year..."

"This is to ensure that if you can win, you can quickly build walls in the local area, or even build a city!"

When Zhang Yue heard this, he also remembered it. Later generations often talked about the Great Wall.

But that usually indicates the Great Wall.

Few people know that there is a Han Great Wall that is several times larger than the size of the Ming Great Wall.

The biggest difference between the Han Great Wall and the later Great Wall is that it has a section of the Great Wall that runs from Hetao to the west and goes deep into the Western Regions, and lasts for thousands of miles.

Zhang Yue was always curious about how the Han family had been able to extend the Great Wall from the former site of the Qin Great Wall in Hetao to Juyan under the technical conditions of BC in just a few decades, and even had time to build a city barrier defense system facing the Qiang people in the Hexi Corridor?

Now, after hearing what Xu Xiangru said, he realized.

It turns out that the Han army will also work as part-time infrastructure maniacs!

This Great Wall is where the army fought and cultivated it?

If you recall it carefully, it seems that this is the case.

In the second year of Yuanshuo, Wei Qing recovered the land of Henan, and he "renovated the blockages of Meng Tian during the Qin Dynasty, and was strengthened by the river." Even a hundred-year-old fortress like Jiuyuan City was repaired from nothing to lightning speed by the Han people.

What's even more exaggerated is the Gaoque Fortress.

As the core and strong city of Qin Great Wall, Gaoque Pass was in the hands of the Huns for 150 years. After wind and sun, Wei Qing attacked Henan and recovered, this once strong city was already shaking.

Therefore, even the Huns did not think about relying on the dangers of Gaoque to stand for help, but instead ran away for desperate efforts.

As a result, a year later, the Right Xian King of the Huns led his main force of the royal court to attack Henan, attempting to recapture the strategic location of Hetao.

Then……

Hundreds of thousands of Huns cavalry were bleeding from their heads under Gaoque...

From then on, the Huns never appeared in Hetao again.

Because the Gaoque Pass, which stands on the banks of the North River, is a strong city that they cannot capture!

In a year, Gaoque Fortress was restored and it became glorious again!

This was inhumane in BC!

After repairing the Qin Dynasty Great Wall defense system, the Han family began a vigorous development plan.

In ten years, 300,000 immigrated, swallowing the entire Hetao into his stomach and completely digesting it.

I just digested the Hetao and didn't even have time to burp.

In the third year of Taichu, Guangluxun Xu Ziwei ordered to build a new Great Wall along Yinshan to the north. The Great Wall spread from Wuyuan Pass to the north at 42 degrees and extends to Luji (now the southern foot of Mount Altai).

At the same time, the Han army had been in Hexi for more than ten years to build cities and walls.

When the Great Wall was completed, the Hexi defense system was also included in the Great Wall Defense.

This is nothing!

The key is that Han Jun was eating what was in the bowl and looking at what was in the pot.

After the Dayuan War, the Han Dynasty built another city barrier defense system in Luntai.

If one day the flanking threat can be resolved and the Huns can be driven south of the Tianshan Mountains.

Perhaps, Luntai will also build a Great Wall connected to Juyan, extending the territory of the Han family to the Western Regions.

Now, looking at the Changshui Captain's wall, Zhang Yue understood why the Han family could become the role of this infrastructure madman before BC.

Gain, this plug-in protection project built with straw, reeds, sand and stone will be very fast when constructed!

Moreover, the raw materials can be obtained locally.

Even its sturdy performance may not be worse than that of the Great Wall of the Ming and Qing Dynasties.

However, the Great Wall of this nature is difficult to resist the invasion of wind and sand.

Therefore, what can be found in the Han Great Wall in later generations are just some ruins.

Xu Xiangru was very proud and started selling Zhang Yue: "If Shizhong wants to manage Monan, it is best to build a city in Monan..."

"The barrier like Juyan Pass can be built in March. Although it is a little different in appearance, it is definitely easy to use!"

"If you are equipped with a trench and arrow tower, and reserve enough sheep head stones, Quda, only five hundred people need to defend, it will be enough to resist the siege of three thousand Hun cavalry for one month!"

"Like Madam Fan's city has changed hands seven or eight times over the past ten years. The Huns destroyed it. After our army recovered it, it has never changed its solidity..."

Zhang Yue listened, looked at the village wall and defense system in front of him, and nodded.

This simple and easy-to-city defense of the city blocks is obviously bullying the Huns without any means of attack.

If the Huns wanted to conquer such a camp, they would probably have to fill it with their lives.

However, what's the use of filling out the next one?

The Han family only surrounded Juyan Pass, and there were five large blocks, small and medium beacon towers, and more than a hundred blocks.

After filling in one, there are still hundreds of hard bones!

Besides, Li Guangli's army was eyeing him. As long as the Huns dared to go, once they were entangled by a certain obstacle, they would not leave!

Unless the Huns can find a way to annihilate the largest mobile corps of the Han army, the Li Guangli corps, in the field.

Otherwise, he would not be able to chew on the move.

But let it go...

The southern desert is vast and sparsely populated, so it is impossible to build a strict defense system like the Great Wall.

but……

You can consider choosing several strategic locations on the grasslands in the south of the desert to build a strong city fortress as a base for operating and developing southern desert.

Of course, Zhang Yue said enthusiastically: "What Xu Gong said makes sense, and I will study it carefully!"

Xu Xiangru immediately became excited as he listened.

Among military achievements in history, the most important thing is to gain territory!

If we can build a defense system in the south of the desert, which is no less than Juyan and Wuyuan.

So……

The contribution of his pioneer, he is probably to be able to increase his fief of at least 2,000 households!

It can also benefit the descendants and descendants and be rich in future generations!

………………………………………

From under the village wall, we came to the gate.

The officers of Changshui, who had been waiting here for a long time, immediately came up under the leadership of the captain and the army Sima.

"The last general and welcome the minister!" Dozens of generals wore armor and bowed slightly. For a moment, the leaves of the armor were jingling and jingling.

Zhang Yue immediately turned over and dismounted and said, "All the generals are exempt from the gift!"

Now, he is the righteous envoy of the emperor's decree, and has the power to command, control and deal with the Changshui Captain.

It was only the emperor who announced that he would be appointed as General Changshui and become a legitimate general.

But in fact, there is not much difference.

With Xu Xiangru's recommendation, Zhang Yue soon basically recognized all the main generals and officials of the Changshui Captain, and at the same time, he called out the information of these generals in his mind and re-created a file for them.

Therefore, Zhang Yue understood the past, personality, surname, hometown and origin of the officers above the Changshui Captain.

As a Han army imperial guard field cavalry unit with Wuhengyi as its main source of troops.

The distribution of officers of Changshui Captain is very interesting.

Among the officers above the military post (Qu) and above, only three were officers from Wu Hengyi’s origin, and these three were all serving as deputy positions.

For example, the Sima Ye Pohu, the army of the Changshui Captain, and the Chief of the Zuo Qu Army Huang Ponu.

Just from the name, we can find out how despised and despised the fathers of these officers from the past.

So much so that the names of their descendants are basically the same as Po Nu, Po Hu, Slaughter Hu, and Killing slaves.

However……

Even so, under normal circumstances, these people have to face the ceiling.
