At this time, the one who guarded Shanhaiguan was Wu Sangui's tribe. The goal of Hubenying was to take down Shanhaiguan.

You know, this is a conquering city and territory. Not to mention the three thousand Hu Ben Camp, even if it is 30,000 and 300,000, it is almost impossible to seize the natural dangerous Shanhaiguan.

But in the confrontation exercise between Zhu Cixuan and Hong Chengchou, it was about siege. No matter what method was used, as long as you could capture the city, it meant that the Liaodong Army had failed.

It was only a month later that he attacked Shanhaiguan. When Hong Chengchou informed Wu Sangui of the exercise, Wu Sangui began to prepare.

We always like to make a final conclusion to a historical figure, and there is nothing wrong with that. But at this time, Wu Sangui was not the traitor who sold his country and sought honor. Like Hong Chengchou's ancestor Dashou, these people were still the backbone of the Liaodong Army.

Current affairs create heroes, but the world is unpredictable. Zu Dashou's surrender to the Qing Dynasty was not voluntary, and Hong Chengchou's surrender to the Qing Dynasty was also helpless. Even Wu Sangui was pressed by Li Zicheng at the beginning, and he was angry with the beauty after being beaten by the crown.

It is true that Wu Sangui was a traitor and a lackey, but Zhu Cilang could not deny him now because of his later bad deeds. At least, Wu Sangui was loyal to the Ming Dynasty in the early days.

To be honest, Wu Sangui is also very good at fighting. Otherwise, he would not have colluded with Huang Taiji in a stone and defeated Li Zicheng. He would not have helped the Qing Dynasty go south and seize the Central Plains.

Shanhaiguan is easy to defend but difficult to attack, and Wu Sangui deploys defense in time. The iron barrel guarding Shanhaiguan is like a guard. It is difficult for the Tiger Army to fight.

As one of the northeastern passes of the Ming Great Wall, Shanhaiguan is called the "No. 1 Pass in the World". The Shanhaiguan Great Wall was built through the six dynasties of Hongwu, Chenghua, Jiajing, Wanli, Tianqi, and Chongzhen. It consumed a lot of manpower, material resources and financial resources. It took 263 years to build a military city defense system that ran the seven cities and the Great Wall on the line.

The entire city is connected to the Great Wall, with the city as the pass. The city has four main city gates and a variety of defensive buildings, making it an extremely complete defense system.

The east is the "Zhendong Gate", the west is the "Yingen Gate", the south is the "Wangyang Gate", and the north is the "Weiyuan Gate". All four gates exist, and the east gate is the "first pass in the world".

When Wu Sangui heard that the Hu Ben Army was coming to attack the city in a month, he couldn't help but smile with contempt. Even his subordinates laughed out loud.

"Hahaha, General Wu, you said we can't even defend Shanhaiguan, so why should we be soldiers? Once Jiannu comes, will we collapse without fighting?"

"Hmph, Your Highness the Crown Prince is finally young. What kind of Tiger Ben Army is invincible? Can you really treat the Tiger Ben Army as a god? Just a few thousand people want to attack the city. Even if they have copper heads and iron arms, we will easily defeat them."

"Hahaha, no matter what, since Governor Hong said that they would come to fight in a month, let's open the door and let him fight. Didn't Governor Hong say that if they lose, we can eat big fish and meat for a month. This kind of advantage will not be taken away."

Wu Sangui snorted and said in a deep voice: "Although we rely on the natural dangers of the pass, we are somewhat unfair. However, the Governor said that we must not underestimate these Hu Ben Army, they are the ones who defeated the Jiannu who set up an ambush. Who can do it in our Liaodong Army?"

When the generals heard this, they immediately became silent. This is true. There is an army that can not only not be ambushed by the Qing soldiers, but also kill the ambushed Qing soldiers.

"Don't worry, General Wu, the last generals are not vegetarians. Once the Hu Ben Army comes to attack, we don't seek merit but no mistakes. We will stick to the city gate and not leave. What can they do to me?"

"Yes, yes, a month's big fish and meat, this kind of advantage will not be taken without vain. I have faded out of the birds and fucked his mother, the Hu Ben Army, these people are so arrogant!"

Wu Sangui was actually a little disdainful in his heart. No matter how hard you can fight the Hu Ben Army, you shouldn't be too arrogant. You have to pull out the eight cities on the Guanningjin defense line one by one, who do you think you are?

If you only have such great ability, you will have already reached Shengjing, the Qing Dynasty, and the Huangtaiji nest.

About half a month later, there was no movement in the Hu Ben Army. Even the spies scattered outside did not move in the Hu Ben Army.

Wu Sangui was a little panicked, and he felt a little confused. If the Hu Ben Army attacked the city a month later, why is there still no trend of their army's activities now?

Then three more days passed, two postmen from Songshan came outside the east gate of Shanhaiguan with quick horses.

A small flag was inserted behind the postman, and the flag was whistling violently under the wind. The postman tied his horse's head and shouted to the city: "Hurry up and open the city gate, I am the messenger sent by Governor Hong!"

The soldiers on the city wall poked their heads out, saw the flag, and waved down: "Open the door, open the city gate."

The city gate slowly opened, and two postmen slapped their horses into the city. The soldiers on the city wall looked around. There was a flat horse outside the east gate, and there was no enemy situation. But they did not dare to be careless. After the postmen entered the city, they hurriedly closed the city gate.

Two postmen entered the city and came directly to Wu Sangui's camp. Wu Sangui heard that he was from Songshan, so he hurried out to greet him.

Wu Sangui bowed: "I wonder what military orders are Governor Hong for the two coming this time?"

The two postmen looked at each other, and one of the postmen took out a letter from his arms: "This is a letter from Governor Hong to you, General Wu should read it yourself."

Wu Sangui was stunned and took the letter suspiciously. The letter was sealed with red lacquer, and it was covered with Hong Chengchou's seal. He tore open the letter and opened it, and was shocked.

Hong Chengchou's handwriting is correct, but the above content made the monk Wu Sangui confused. Hong Chengchou's letter said that the Hu Ben Army exercise was cancelled.

The plan changes, Long live to transfer His Highness the Crown Prince back to Beijing. Two days later, His Highness the Crown Prince led his army through Shanhaiguan, hoping to contact him in time.

What a fool, Wu Sangui was really annoyed when he saw Hong Chengchou's letter. Isn't this nonsense? He is using military orders as a joke.

It was agreed that the Hu Ben Army would come to attack the city in a month. More than half a month has passed, and there are still more than ten days left. If you say you can cancel it, you can cancel it.

I heard that Wu Sangui was contemptuous in his heart, but he still did not dare to neglect his scrutiny. Over the past half month, he has been strengthening the fortifications and even arranged spies outside the city, always paying attention to the movements of the Hu Ben Army. Now, if you say you can cancel it, you can cancel it.

However, the letter said that the plan had changed, and Emperor Chongzhen transferred the prince back to the capital. This was quite in line with the personality of Emperor Chongzhen. After all, Chongzhen was always worried about arranging his son in the border.

These two postmen were old acquaintances, and were formerly subordinates of Hong Chengchou, Songshan. In addition, the letter was red-lacquered seal, Hong Chengchou's Governor General's seal, and his handwriting was also his. Wu Sangui sighed: "Forget it."
