Juyansai, far away in Hexi, is the most brilliant pearl in the crown of the Han Empire!

There is hardly one of them!

It's so majestic!

So much so, from a distance of dozens of miles, you can clearly see the landscape of this largest and strongest fortress group of human beings before the Western Yuan Dynasty - dozens of fortresses, stretching into groups, forming an iron gate, locking the entire Juyanze in it!

And that's just the surface of Juyense.

To get a glimpse of it, you have to expand your horizons hundreds of miles.

Then you can clearly see this largest, most fortified, most extensive, most powerful and most terrifying fortress group in human history so far - Hanjuyan Fortress Group!

Just the main stuff group, there are as many as seven!

They surrounded Juyanze, like a big iron gate, locking this strategic place and the road where the Huns raided Hexi from the direction of Junji Mountain!

With the current technical conditions, it is impossible for any army or country on this earth to capture this fortress group!

You don't need to look at anything else, just turn on the computer and go to the Internet to check the number of Han Dynasty barrier ruins excavated by archaeologists in the Juyan area, and you can know how huge the scale of Juyan is? - The number of the Cüjenhanse, which was only used to identify the discovery, was ranked from A to T.

The distribution area is 350 kilometers long and more than 70 kilometers wide, covering Ejina Banner in Inner Mongolia and Jinta in Gansu.

The excavated fortress group is fully in line with the records in the history books.

The smallest of these fortresses had at least ten or more beacon forts and three or more fortresses.

The largest Sanjing Fortress has three criss-crossing beacon fortresses, and there are hundreds of large and small beacon towers, fortresses, and military forts, so that the introduction text made by archaeologists for it adds up to dozens of pages!

Among them, there are countless historical cities and large fortresses.

For example, the Black City Plug and the Cover Plug are all part of the Triple Well Plug.

And now, what Han Zeng saw in front of him was nothing more than the middle fortress group in the Juyan fortress group, Zhenbei Fortress, a fortress group deployed along the north bank of the lower reaches of the weak water.

The total length is only twenty or thirty miles, and there are only a dozen beacons and fortresses.

Even so, in Han Zeng's eyes, this fortress group is still spectacular.

The tall beacon tower, along the weak water, stands on its left bank, blocking the desert and the Gobi outside it.

And the majestic fortress city must be built every thirty miles.

So that the entire weak water is blocked by an iron wall.

It ensured that if the Huns went crazy to attack, then the Hun cavalry who crossed the Junji Mountains and the desert would definitely not be able to easily get the slightest supply here - they would either come to hit the fortified Zhenbei Sai, or they would die of thirst and starvation in the Gobi and the desert.

This is a very mature defense idea, which was used in later generations to the Ming Dynasty - the nine-sided defense of the Ming Dynasty, and it also followed this idea - using fortresses and beacons to enclose water and grass, and throw the Gobi and desert to the enemy.

However, the difference is that the defensive nature of Juyansai in the Han Empire is weaker than the offensive nature.

In the last thirty years, its defensive stats have been used no more than ten times.

However, the Han army took Juyan as a base and took the initiative to attack thousands of times!

The number of large-scale sorties exceeded fifteen!

and Qin Shi Huang built the Great Wall, not to defend against the Xiongnu, Linhu, and Donghu, but to attack generally.

The Han Dynasty built the wall of Yansai and the west side of the river, also in order to better and faster attack the Xiongnu in the Western Regions and Mobei.

Therefore, what Han Zeng saw in these beacons and fortresses was more of a strong offensive characteristic.

For example, the wide road, the flat grassland in front of the fortress, and the dense farmland surrounding the fortress and the beacon tower, and even the road between the gate of the fortress and the beacon tower, are exceptionally wide.

These are all prepared for the attack, and they are all designed so that the army can pass through these places faster and fight the Huns!

The only thing that made Han Zeng not very satisfied was that the greening was not enough.

Janebec is built along the lower reaches of the weak water, standing next to the river, but the vegetation on both sides of the river has been greatly affected by human and agricultural activities.

In many places, both sides of the river embankment are farmland.

That's the problem.

Continue along the Janebec Sai, and after a day, you will enter the range of the Jiaqu Housai.

This fortress group was built along the west bank of the Black Water and connected to the east of the fortress in the north of the city.

Here, the situation is even more dire, as large sums of wetlands have been reclaimed for agricultural production, planted by soldiers from the fortified groups, and the output used as military rations.

The Jiaquhou fortress group, which stretches for hundreds of miles, needs to supply tens of thousands of soldiers and civilians.

Naturally, the pressure is extremely high, and the damage to the environment is also relatively serious.

This made Han Zeng couldn't help frowning, he was not an extreme environmentalist.

In his eyes, the environment exists for human needs, survival and development.

In his eyes, those petty animal protectors and extreme environmental protectors in later generations are not much different from stupid 13.

But if the damage is too severe, the cost is also devastating.

Not to mention, today's Juyan area, but the lungs of Hexi, "Yu Gong" said: shaped like the moon born on the fifth day, the satellite remote sensing images of later generations, the ruins of ancient Juyan, like a person's lungs, unfortunately, this lung has died, turned into a desert, leaving only traces of ancient rivers and ancient lakes, and these traces will gradually be buried by the desert, and eventually disappear.

Han Zeng didn't want the future to happen again.

Because, once the oasis becomes a desert, the lake becomes a Gobi, and the wetland becomes a desert.

Then everything now will cease to exist.

Even if you just consider the moment, soil and water conservation is of great benefit to agricultural development and urban fortifications – at least, without worrying about flooding or drought.

Therefore, along the way, Han Zeng conceived the future greening and vegetation plan of Juyan in his heart.

These things may be difficult for others, but they are a piece of cake for Han Zeng.

There is space in hand, and the reversal is just a cover.

The only thing to consider is how to act and how to lay out the layout.

Compared with the environment, the problem of people is obviously bigger!

Coming all the way from Zhenbei Sai to the Jiaqu Housai of the Heishui River, Han Zeng saw all the way that this Juyan Defense Area is now bleak and desolate.

Almost every family wears filial piety, and every household is sad.

"Zhang Anshi really left me with a big mess!" Han Zeng shook his head, feeling a little tired.

In the battle at the foot of the northern foot of the Tianshan Mountains, it seemed that Zhang Anshi had lost only three or four thousand.

But the key is that the losses are all elites, and they are all the soldiers and civilians of Juyan.

In particular, the loss of Captain Juyan is too tragic!

More than 2,000 people were killed, and the rest were all frostbitten to varying degrees.

Now, Zhang Anshi patted his ass and returned to Chang'an, while Han Zeng became a pick-up man.

While he took over the territory and power of the four counties in Hexi, he also took over this mess.

He had to deal with the pensions and maintenance of the Second Division Army and the Juyan Commander, as well as the placement of the disabled soldiers.

Of course, Han Zeng can also dump the blame on Zhang Anshi, and let these soldiers and widows go to Zhang Anshi to be responsible.

But the problem is that Han Zeng knows that there will only be one consequence of doing this - these poor people will be left unattended.

After returning to Chang'an, how could Zhang Anshi, who was difficult to protect himself, have so many resources and abilities to take care of these people?

Hold on, at most save those officers above the military waitlist.

The middle and lower class soldiers will all become victims.

And as soon as this example is opened, the future will look good.

Think about it, if you die for the country, but those who are wounded in the war for the country will not be beneficial, resettled, and cared for.

In the next war, who will be willing to serve the country and fight bravely?

I am afraid that it will become the Lu country after Confucius released the fugitives - everyone is afraid of the national war and has the courage to flee for their lives.

Therefore, this plate, Han Zeng has to take it even if he doesn't take it!

Not only do you have to go next, but you also have to get things right!

If you don't say it, you have nothing to say, at least you have to get by, and there must be no tragic things like martyrs' orphans and disabled soldiers committing suicide because they can't survive!

In that case, Han Zeng, the general of Yingyang, would probably lose his prestige in the hearts of the people of the four counties of Hexi, and lose face.

However, it is extremely difficult to do this thing well.

Resources, money, systems, and policies are all indispensable.

And it involves all aspects, involving countless interests, Han Zeng was a little clueless for a while, he could only walk, observe, and think at the same time.
