Wudu County Governing Office under the city, the government is full of people.

Xiahou Yuan issued an order to the generals to send troops to attack Yangping Pass: "Three days later, raise troops to attack Yangping Pass, Cao Chun, Cao Zhen!" ”

"The last general!" The two of them walked out.

Xiahou Yuan ordered: "Let the two of you lead the tiger and leopard to ride as the vanguard!" Open the road in the mountains and build bridges in the water! ”

"No!"

Xiahou Yuan continued: "Ben Shuai leads the Chinese army by himself, Zhang He, Guo Huai, you two lead the army to escort the grain and grass behind!" Zhang Ji, you stay behind to defend and raise and transport grain and grass for my army! ”

"No!" The crowd took orders.

"Alright, let's go down and prepare, and in three days, lead the troops to the battle!"

His Royal Highness Cao Zhen, seeing that Xiahou Yuan's orders were all ordered, couldn't help but stand up and arch his hand: "General, don't you send a team of soldiers and horses to guard the Guancheng Road?" ”

Guancheng is located in the Qianli Mountain Road from Baishui Pass to Yangping Pass, and its location is about in the middle, 500 li away from Baishui Pass, and 500 li away from Yangping Pass.

"Sekijo Road? Where is this city? Xiahou Yuan frowned when he heard this, but he was confused, he had never heard of Guancheng.

It's no wonder that Xiahou Yuan hasn't heard of Guancheng, this Guancheng is located in the deep mountains and old forests, it is an inaccessible place, Zhang Lu and Liu Zhang have a bad relationship, and there are few people circulating between the two places. Nowadays, even the locals of Yizhou don't know much about Guancheng, let alone Xiahou Yuan, a person who is not familiar with the geography of Yizhou.

"Here!" Cao Zhen saw that Xiahou Yuan didn't know about Guancheng, so he walked to the map behind Xiahou Yuan and pointed it out for Xiahou Yuan.

However, Xiahou Yuan still didn't find Guancheng, because Guancheng was small and not marked on the map, and Cao Zhen only pointed out a general location.

However, Xiahou Yuan also knew what Cao Zhen said about Guancheng, Xiahou Yuan glanced at Cao Zhen, and said in a deep voice: "This place is located between the mountains and mountains, hundreds of miles away from Yangping Pass, stationed in Guancheng Road, what is the significance?" ”

The generals were also quite puzzled, Guancheng is hundreds of miles away from Yangping Pass, what is the use of sending troops to be stationed there?

Facing the surprised gaze of the generals, Cao Zhen arched his hand and explained: "In order to prevent the Shu soldiers from going north from the Sword Pavilion to Yangping Pass!" If you can garrison Guancheng and cut off the Guancheng Road, then the Shu soldiers will not be able to go north! ”

Xiahou Yuan laughed when he heard this, stroked his beard and smiled: "Zidan, you are too worried, right?" From the Sword Pavilion to Yangping Pass, thousands of miles of mountain roads, grain and grass are difficult to transport, Liu Bei has been on the battlefield for a long time, how could he make such a faint move to lead troops out of Yangping Pass from Sword Pavilion? ”

Cao Zhen advised: "Don't be afraid of 10,000, just in case, if Liu Bei sends a partial teacher out of Yangping Pass, what should I do?" In my opinion, it is better to send 5,000 men to seize the city and cut off the road to the city! ”

Xiahou Yuan waved his hand and said: "If it doesn't work, Liu Bei will definitely go out of Bazhong to attack the hinterland of Hanzhong, and Yu Wei Gong will fight a decisive battle in Hanzhong." I need to take Yangping Pass as soon as possible and go to join Duke Wei, 5,000 soldiers and horses is not a small amount, Liu Bei's troops are equivalent to Duke Wei, these 5,000 soldiers and horses cannot be missing!

As for Liu Bei's dispatch of troops out of Yangping Pass, this is impossible, and their grain and grass are heavy, and they can't keep up. If Liu Bei really sent troops, considering the supply of grain and grass, he would only be able to send a few thousand men to march lightly and come to harass me and delay the time for me to join Wei Gong, so that his main army could defeat Wei Gong during this period.

It's just a few thousand people, so what's the point? Let them come, if they dare to come, they will destroy them. What's more, we are so close to Yangping Pass, we can arrive at Yangping Pass in three days, and if the Shu soldiers go out of Yangping Pass, thousands of miles of mountain roads, they will have to walk for at least twenty days, and by that time, we will have already taken Yangping Pass!

In this way, they can't even harass and delay our army's plan, so I said, Liu Bei will not send troops out of Yangping Pass, Zidan, you still have to learn! ”

"Yes, it's the last general who is stupid!" After listening to Xiahou Yuan's analysis, Cao Zhen also felt that there was some truth.

Thousands of miles of mountain roads, the transportation of grain and grass is a big problem, if Liu Bei goes out of Yangping Pass, he will also send thousands of people at most to move forward lightly, harass them, and delay the task of Xiahou Yuan's soldiers and horses.

However, Xiahou Yuan had 50,000 soldiers and horses, and only a few thousand people, so there was no need to worry at all. Seeing that Xiahou Yuan had his own ideas, Cao Zhen stopped pressing.

Xiahou Yuan waved his hand and said, "Okay, let's go down and prepare, three days later, the troops will go out of Yangping Pass!" ”

Three days passed.

Xiahou Yuan's 50,000-strong army has been rectified, and spring is blooming. After several days of fine weather, the roads were dry and suitable for the march of the army.

The army set off as scheduled.

Cao Chun, Cao Zhen led two thousand tigers and leopards as the vanguard.

Xiahou Yuan led the Chinese army,

Guo Huai and Zhang He escorted the grain and grass behind, and Zhang Ji stayed behind to argue.

50,000 soldiers and horses, mighty and mighty came to Yangpingguan.

But it is said that this Yangping Pass is one of the most dangerous fortresses in the world.

Yangping Pass, north of Jigong Mountain, south of Jialing River, terrain is extremely dangerous. The south can enter Sichuan, the north passes through Luoyang, the west reaches Longnan, and the east reaches Hanzhong.

If Shu gets it, it can overthrow the enemy and respect the royal family; It can encroach on Yong and Liang, and expand the land; The next can stick to the key points for a long-term plan.

Therefore, Guyang Pingguan has been regarded as "the throat of Shu" and "the gateway of Hanzhong" since ancient times, and it has the sigh of "the most dangerous in Han" is as good as Yangping!

Yangping Pass is so important, so its construction is also particularly steep.

Between the Jialing River and Jigong Mountain, Yangping Pass is located here by the mountain.

Hearing that Xiahou Yuan came with 50,000 troops, Yangping Pass also launched a defense.

Ma Chao is an old general, and Xiliang Pang De is the guard general of Yangping Pass, but although Pang De is the main general, but in Yangping Guanzhong, Pang De is not the only one who makes the decision.

Pang De is a general, Zhang Lu naturally will not completely hand over the fortress of Yangping Pass to Pang De, although Pang De is the main general, but Zhang Lu has appointed another supervising army, named Yang Ang, is a general of Hanzhong, supervising the army, sometimes more than the main general.

For example, in the battle of Shu Han to destroy the country, Deng Ai and Zhong Hui were the main generals of the two armies, but they were killed by the prison guards, which shows the great power of the prison army.

In addition, Yang Ang has always been above the top, looking down on Pang De, a demoted general, and receiving the post of supervising the army, it can be said that it is this person who is really in charge of Yangpingguan.

In fact, Zhang Lu was facing the attack of Liu Bei and Cao Cao at the moment, and he had made a decision in his heart.

That is to take refuge in Cao Cao.

However, his subordinate adviser Yan Pu suggested to Zhang Lu: Now that he is forced to surrender to Cao Cao, he will definitely not be reused, so it is better to send troops to resist Cao Cao first, and when Liu Bei occupies many cities in Hanzhong, Cao Cao is impatient, he surrenders to Cao Cao, so that he can be reused by Cao Cao.
