Next, after thoroughly organizing the Yangguan City, Liu Hongji's army temporarily stationed.
According to Liu Hongji's intention, they needed to wait for the arrival of the other two armies here and then approach the hinterland of Tuguhun together.
And during the waiting few days, Xiao Han was not idle either.
He asked Xiaodong to go and found all the maps, county annals and other historical materials that can be found, and then reorganized them.
Since what they looked at before was all about geographical maps of the Western Regions, after all, the most important thing about the army was to go the right way.
After I got free this time, I saw the map of Tuguhun outside the Tang Dynasty, Xiao Han realized that the Wanlong clan leader who had been shouting at the city wall before seemed to be right.
The reason why this Yangguan City, which has existed since the Han Dynasty, was built here is to strangle the throat of Tuguhun!
Perhaps, you can doubt the corruption of the great man.
It can attack the Han harems and interfere in politics.
You can also despise the eunuchs of the Han Dynasty as power!
But the only thing you cannot deny is the bravery of the great man!
The country is always destroyed by weak, but the Han Dynasty is the only one who dies by strong!
In "Book of the Later Han Dynasty", Wang Fuzhi summarized the heavy history of the 407-year Han Dynasty in just one short sentence!
And Yangguan!
It is a nail that was set up here with its advanced military vision, and a nail that was stabbed between the enemy's confidants!
But the big men at that time wanted to be on guard against Tuguhun.
After all, seven hundred years ago, the ancestors of Tuguhun were probably still in Changbai Mountain and were playing with Siberian tigers.
The one who occupied this place at that time and could pose a threat to the great man was the same powerful Wusun, Kucha, and Loulan!
That's right, it is Wang Changling's ancient country in "Seven Poems of Military Journey, Four of which: Gold is worn with golden armor after hundreds of battles, and Loulan will never return until it is destroyed.
Although I don’t know what Loulan did, all the Central Plains dynasties are obsessed with it.
But from this poem, we can also see the difficulty of capturing this place!
Located in the southwest, surrounded by mountains and ridges!
Kunlun Mountains, Qilian Mountains, and Tianshan Mountains, these natural dangers are all here. No matter how hard the Central Plains dynasty strives, it has never been able to incorporate this place into its territory for hundreds of years.
But everything in this world has advantages and disadvantages!
If these numerous natural dangers are the protection given here by God, protecting it from being disturbed by the outside world.
But in the same way, it has also become a cage locked here, making it impossible for people here to enter and exit easily!
As for the gateway to this cage, it is a valley only a few hundred miles away from Yangguan!
If they want to jump out of this cage, they must pass through the valley and Yangguan!
As long as Liu Hongji guards Yangguan, the Tuguhun people inside will be just a group of mice blocked from the hole and will not be able to escape!
"Mr. Marquis, do you say that Yangguan is the gateway to Tuguhun? But there is no village in front or shop in the back. There is a desert around it. Why can't they walk around?"
After hearing Xiao Han's analysis, Xiaodong didn't really believe it.
In his consciousness, only levels like Jianmen Pass and Hulao Pass that are like the one who is a pass and ten thousand men cannot open are called levels!
And this Yang Pass is hanging alone in the middle of this desert, with no soil mounds on all sides. It’s not that people can just walk around as they want. What is this level?
"Levels, levels! You don't have to be closed!" Xiao Han gave Xiaodong a blank look and said angrily: "As long as it can block others and not let people pass by casually, that's fine?"
"Stucked? Why are you stuck? People can still come here with a slutty look?" Xiaodong stared at his innocent eyes and looked up and down, but he didn't see what magic there was here that could make Tuguhu people.
All attracted to it.
"Idiot!" Xiao Han slapped Xiaodong on the head who was spinning around his head, and Xiao Han scolded with regret: "If you go out in the future, don't say you know me! You have no progress at all! Haven't you noticed that you are near here?
, is there only water here?"
"water?"
Now, Xiaodong finally understood.
It seems like I am coming all the way from Yumen Pass, with yellow sand and Gobi in the middle. Not to mention water, I have never seen a slightly moist quagmire before!
Only in this Yangguan City can there be a few wells that can be poured into water!
As the Marquis said, they occupied this water source, but they just stuck the Tuguhu people who wanted to cross the Gobi Desert! If they don’t want to be thirsty and want to replenish some drinking water, then there is no place to go.
Can you come to Yangguan City honestly!
"Look at this!" Xiao Han saw Xiaodong suddenly realize, and pointed to the map spread out on the table and said, "Did you see, once they come out of the valley, whether it is east, west, or north,
All are arid deserts!
The only place where we can replenish water is the Yumen Pass there! Now, we are blocking here, how dare they bypass us and go to Yumen Pass? Are you afraid that we will stab them in the butt?"
"Ahem, then they won't bring more water?"
Xiao Han had just finished explaining to Xiaodong, but unexpectedly, Lanzi came over and said with a disdainful expression: "As long as you bring more water, don't you also go wherever you want to go?"
"I think Tuguhu people may not need to bring water, just bring you with you. When water is short, you can get a stream of water in your head..."
Xiao Han was completely powerless because he felt that in his previous life, he must have been a water dispenser, and his head was filled with water!
Also let the Tuguhun people bring more water?
Anyone who can understand a little bit of the map will not ask such a naive question!
This is not within the pass. You can meet a village just by walking a few miles!
This is the Western Regions, an unmanned land that can be seen for hundreds of miles at any time! How much water do you need to bring to get out?
Besides, there are no off-road vehicles these days. If you want to rush on the road, besides your legs, there are only cattle, horses and livestock!
And if you drive the livestock, how much water does the livestock drink every day?
Don't talk to him about camels or desert boats!
This thing is precious even in the later generations!
I remember the last time Xiao Han saw a camel in Dunhuang. He had nothing to do and asked for the price. As a result, the offer from the Western Region merchant almost shocked him!
A camel, he actually dared to ask for fifteen cows!
Just like that, the merchants in the Western Regions even called for cheap sales! The value that such a camel can create is far from comparable to that of fifteen cows!
Just such a precious thing, Xiao Han didn't believe that those earthy people who were desolate in the Tuguhun could afford it!
