The most famous pass among them is Juyong Pass.

However, Juyongguan is not enough to ensure the security of Youzhou County and Ji County.

Because even more than a thousand years later, the Ming Dynasty of later generations could not stop the northern cavalry even though they spent countless money and food to build the three inner passes and garrisoned heavy troops.

Later Jin Dynasty repeatedly bypassed Juyong Pass and plundered the prefectures and counties around Kyoto.

Once the cavalry enters the endless fertile land of Hebei, they can gallop around at will.

The famous Tumu Fort Incident in history also happened not far north of Juyongguan.

Then the Oara army took advantage of the victory and moved south, easily crossing the fortresses in the Juyong Pass area and approaching the walls of Kyoto.

Therefore, just like defending the Huai River to defend the Yangtze River, if you want the pass with Juyong Pass as the main hub to be effective, you must first defend the Guangning City in the north guarding the mountain pass.

This requires close cooperation between the various gates and gates, which is a great test of the tacit understanding of the defenders everywhere.

Otherwise, if there is a mistake in one place, it will form a chain reaction and there will be loopholes everywhere.

Otherwise, just like the Han and Tang Dynasties, they could simply take the initiative and send troops outside the fortress, using it as a battlefield so that the enemy would have no chance to attack the border fortress.

Since Ke Bi Neng was driven to Jiuyuan, the northern border of Youzhou has become much peaceful, at least for the Wei State.

Logically speaking, if the Wei State wanted to buy horses from the Hu people, then Guangning City, facing the northern desert, would be one of the best trading places.

For someone like Wu Niu, who would rather go a long way from Danhan to Pingcheng than be close by, it is not a priority.

"Actually, we originally wanted to go south and sell these livestock to the Wei people."

The translator explained, "But I don't know what happened. I heard that a tribe came from nowhere in the Guangning City area."

"They were entrenched in the mountains. Not only did they often attack the tribes who went south to trade, they even defeated the Wei troops transporting horses from Guangning City to the fortress."

"They come and go like the wind, they are extremely fierce, we can't defeat them at all..."

At this point, the translator seemed a little embarrassed and coughed:

"But now that I think about it, we are lucky to have them, which makes us want to try our luck here."

Xu You didn't change his expression when he heard the translator's words. He didn't know whether he didn't mind or didn't realize there was anything wrong with it.

He just asked:

"What about the Wei thieves in the south? Their horses were robbed? Should we just ignore them?"

The translator shook his head: "Then we don't know. But we heard that the Wei thieves in the south sent people to look for them, but there should be no results."

"Otherwise, that road wouldn't be impassable until now..."

When Xu You heard this, he smiled and said nothing.

If there is a secret passage, there will be ghosts.

No, even if it is passable, there are still ghosts.

The ghost of the ghost king.

Pingcheng is to the west, and Guangning is to the northeast of Pingcheng.

The two places are separated by the remaining veins of Yinshan Mountain and Yanshan Mountain.

But as mentioned before, the area from Guangning to Juyong is located at the intersection of the Yinshan Mountains, Yanshan Mountains and Taihang Mountains, so the mountains are low.

Therefore, starting from Pingcheng, the cavalry can easily reach the rear of Guangning City and directly cut off the connection between Guangning City and Juyongguan.

Going north, you can plunder the area around Guangning City.

Going south, you can pass through Junduxing, one of the eight passes in Taihang, and go straight to Juyong Pass.

Facing the elite cavalry of the Han Dynasty led by Liu Hun, let alone the barbarians on the grassland.

Even for the Wei thieves stationed in the Juyong Pass, as long as they have the courage to come out from Juyong Pass, Liu Hun can teach them how to behave.

The Youzhou of today is not the Youzhou of the past.

Sima Yi retreated to the Central Plains and did not care about the life and death of Jizhou and Youzhou. Of course, he did not have the right to issue orders to the two states for the time being.

As for Cao Shuang, who had a great reputation, his ability was insufficient. In addition, Hebei was too far away from Xuchang, and there was Sizhou occupied by Sima Yi in between.

Therefore, the land of Hebei is not his focus at all.

Now, he only thinks about how to recruit the armies in the Jianghuai and Jingzhou areas to compete with Sima Yi, who has a heavy army.

Therefore, as long as Liu Hun himself did not seek death, he would lead his cavalry to attack important pass cities such as Guangning City or Juyong Pass.

Coupled with the material support from Pingcheng, no one from Guangning City to Juyongguan can be his opponent.

At the same time, this is one of the reasons why Feng Youqi must rebuild Pingcheng.

The Datong Basin is full of coal, but Pingcheng's geographical location is extremely important.

Leaving the desert in the north, connecting Jiuyuan in the west, and controlling the military capital in the east, we are ready to break Juyong Pass and capture Hebei at any time.

Listening patiently to the complaints of Wu Niu and the translator, Xu You had a sympathetic expression on his face.

Then he said to them:

"My friends, you now know that you can get a better price here. I believe that even if that road is opened in the future, you will never trade with the Wei people again, right?"

Wu Niu nodded, said something, and then drank the wine in the bowl.

"Dear Sir, this is natural. No one would want to have trouble with these food and clothing."

"You're so right! Which one of us does business not to make more money and food? This really resonates with me!"

Xu You patted his thigh, then sighed:

"To tell you the truth, I thought that by offering such a high price, I thought I would be able to collect a lot of livestock this year."

As he said that, he shook his head, "I didn't expect...ah!"

He looked at the two people opposite him again and begged:

"So I have a grudging request here. I would like to ask you two for a favor."

Wu Niu got a lot of benefits today, and was treated to food and drinks by Xu You. After drinking so much, he wished he could treat Xu You as his own brother.

No matter what kind of help Xu You wanted, he just agreed loudly and patted his chest.

"Actually, this matter is very simple. I just ask you two to go back to Danhan Mountain and talk about the situation here."

"If more people come here next year," Xu You thought for a moment, then made up his mind and said, "Well, if you can get more people to come over and trade."

"As long as they tell me your name, every time they sell me a war horse or a big black cow, I can give you a piece of wool for free."

One war horse has twenty pieces of wool, and the commission is five percent, which is not high.

But Wu Niu is obviously not very good at arithmetic.

When he heard Xu You's words, his eyes, which were already a little drunk, suddenly lit up. He, who was not good at speaking Chinese, could actually pronounce the words clearly:

"Free gift?"

Xu You nodded: "Yes, it's free. No matter what method you use, as long as you can get them to come to me to sell war horses, I can give you an extra horse for free."

"Where's the sheep?"

Xu You shook his head: "We don't want sheep. We only need war horses and big black oxen. Ordinary horses and oxen will not do."

Although the conditions are a bit harsh, but...

"no problem!"

PS: In the Ming Dynasty, there were three internal and external barriers to prevent grassland.

The outer three passes refer to the three passes centered on Datong, which are now in the hands of Ji Han.

The Neisan Pass refers to the three passes with Juyong Pass as the focus, currently within the scope of Youzhou.
