Hong Chengchou said: "Does the prince remember that three days ago, the slave said that as long as our army bypasses the defense line of the thief army, the gentry and officials in the capital will welcome you? Only by avoiding the fire in the backyard of the thief, the thief will collapse without fighting?"

Dorgon snorted: "Isn't this impossible to get around? The thieves are like a group of thieves, and the fortress world is only a few hundred steps. If we force ourselves to pass through it, our army will suffer many losses."

"You can ask the Mongolian light cavalry and our cavalry camp to pass through Yanshan on the northern foot of the mountain. The prince can ask someone to escort the slave to Zhangjiakou. When passing by the capital, the slave sends people to contact the gentry in the capital. Our army then joins the Mongolian to enter from Zhangjiakou, and then causes the trespass to catch fire in the backyard! The slave can take advantage of the opportunity to seize the capital and cut off the food and grass of the trespass. Once the trespass army is out of food and the general's morale is disintegrating, our army can defeat the trespass army without bloodshed." Hong Chengchou said.

Dorgon frowned: "But this plan is too risky. If the bandit army builds a city along the seaside passage, there must be cavalry moving in Yanshan Mountain. Our light cavalry goes deeper into the army alone. If we encounter a bandit army, it will be very bad. If Mr. Hong is damaged, our army will be like a broken arm. Our army goes deeper into the army alone and is not suitable for straw and food. If we cannot retreat with all our duties, our army has no straw and food, what can we do?"

Hong Chengchou said: "Prince, our army has changed into the Ming army's armor banner. Just bring seven days of food and grass. When the slave goes to Zhangjiakou to find Fan Yongdou and others, you can form a Green Camp army behind the bandit army! With Mongolian cavalry and our cavalry camp, plus the green camp, and gentry as internal support, you can easily seize the capital and cut off the thieves' food route!"

"Fan Yongdou!" Hearing these three words, Dorgon's eyes lit up, "If you get help from the Fan family, the thief will be defeated and will not be far away!"

Dorgon then assigned Hong Chengchou three thousand Mongolian Eight Banners Light Cavalry and two thousand Manchurian Eight Banners Cavalry cavalry, plus two hundred white-armored Bayala soldiers and three hundred red-armored Bayala soldiers, a total of 5,500 cavalry were all lightly equipped. Each Mongolian Eight Banners soldier was equipped with two Mongolian horses and replaced with the cotton armor of the Ming army; the heavy cavalry of the Eight Banners of the Manchurian Eight Banners took off the inner chain mail, leaving only one cotton armor, and the shapes of the war horses were removed. In addition to the Wuzhumuqin horse for combat, he was also equipped with another Mongolian horse. Each Qing cavalry only brought seven days of dry food, and was equipped with some food such as beans for war horses.

The Eight Banners transformed into a Ming cavalry after five thousand and five hundred busy hours.

After it became dark, Hong Chengchou personally brought 5,500 Manchu and Mongolian cavalry and broke it into pieces and entered the Yanshan Mountains.

First, the two hundred white-armored soldiers who were scouting cavalry left first, followed by three hundred red-armored Bayala soldiers, and then the Manchu and Mongolian cavalry entered the Yanshan Mountains.

After a while, the white-armored soldiers captured several Shun Army prisoners and obtained the order from Shun Army that night through separate interrogation.

On the way, they encountered the Shun Army cavalry. The Manchu and Mongolian Eight Banners soldiers, relying on their Ming army uniforms and banners, and had the Shun Army commands obtained in advance, made these Shun Army cavalry mistakenly think that they were meeting the surrendered Ming army. In addition, the sky was dark, so the Qing army easily escaped.

Since Shanhaiguan fell into the hands of the Qing army, although Zhao Peng built fortifications along the corridor from Yanshan to the beach, there were loopholes everywhere in the pass after Shanhaiguan, and the Qing army's light cavalry could find the loopholes and drill in any of them.

The Qing cavalry disguised by the defense line of the Shun Army and entered the Jingji area, but they did not stay. Hong Chengchou just sent a few spies disguised as civilians to contact the former Ming officials in the capital. Then he personally led the Qing cavalry disguised as Ming Army and headed straight for Zhangjiakou without stopping.

Although some of the Shun Army cavalry disappeared, the Shun Army did not accept small-scale battles with the Qing army's scouts and mail cavalry at night, and no one suspected them.

With the former Ming army uniform and the flag of Shun army, the Manchu and Mongolian light cavalry, who had a man and two horses, traveled 180 miles a day, and in less than seven days, it took more than 900 miles.

In Zhangjiakou, the one who stayed here was Jiang Xiang's Qianzong Battalion. Jiang Xiang, who had surrendered to Dashun, took all the main forces to Shanhaiguan. The Qianzong Battalion that left here said there was one thousand people. Because of the empty salary, the troops were actually only more than 500. But even if there were only more than 500 people, with the strong Zhangjiakou Fort City, it was not possible to conquer 5,000 Manchu and Mongolian cavalry. These Manchu and Mongolian cavalry who came lightly did not have any siege weapons at hand, so there was no way to take Zhangjiakou City.

Before it was dark, Hong Chengchou sent people to sneak into Zhangjiakou City as civilians, and the Dashengkui Store in the same city got in touch.

The Dashengkui Shop is the shop of the Jiexiu Fan family in Zhangjiakou. This shop that appears to be a regular business, but in fact it has long been secretly connected to the intelligence station of the Later Jin Dynasty. The Dashengkui Shop not only secretly provided food, iron, gunpowder and other strategic materials to the Later Jin Dynasty, but also provided various important information to the Later Jin Dynasty. It was the Fan family's outstanding contribution to the Qing Dynasty that laid the foundation for the Qing Dynasty to unify the world later.

Two men wearing cloth hats and dressed in yellow short-dressing clothes, and the merchants walked into the Dashengkui business. As soon as the two men came in, they shouted to find Manager Fan.

Fan Yongdou's son Fan Sanbao was in the store. Seeing that the two of them looked fierce and did not look like Han people, he did not dare to neglect them, so he quickly asked someone to invite them into the yard behind the store.

The two took off their hats and revealed a big bald head and the rat-tail of the money behind them.

Fan Sanbu immediately saluted respectfully: "I wonder what happened to the two adults coming?"

One of them said, "We are here to find Lingzun and meet with important things!"

Fan Sanbu said: "Please go upstairs and wait a moment. My father will go out and return in half an hour."

After about an hour, Fan Yongdou came back from outside. When his son told him that there were two adults from Manchuria, he quickly ran back to the backyard like a flying trip and ran to the second floor.

Fan Yongdou went up to the second floor and saw two Manchus sitting on two magistrate chairs at a glance. He hurried forward and saluted respectfully: "I don't know that the two lords are coming, so I have to wait for a long time. I wish you forgive me for your sins!"

One of them sneered: "I am the Manchu Bayala Zhuang Dadoron."

Another said: "I am the Manchu Bayala Zhuang Daerdenbu."

Fan Yongdou sat down, bowed his hand and asked, "What are the things that two sirs have come?"

Duololong said: "Now Wu Sangui, the general of Shanhaiguan in Ming Dynasty, has surrendered to our Qing Dynasty. My Qing heavenly soldiers have entered Shanhaiguan, but the thieves resisted stubbornly and stopped my Qing heavenly soldiers. The master ordered us and the other two to come to ask Manager Fan to help me with the Qing Dynasty. When the matter is completed, the regent will have a heavy reward!"

"What kind of reward does the prince have?" Fan Yongdou asked.

Duololong smiled and said, "The prince said that the Fan family has made outstanding achievements in the Qing Dynasty. If we can make great contributions and help the Qing Dynasty seize half of the northern territory, the Fan family will be named the Imperial Merchants and can freely walk anywhere within the Qing Dynasty and enter the palace freely!"

"How can the prince help the villain?" Fan Yongdou asked hurriedly.

"Very simple," Erdenbu smiled, "Now, Lord Hong Heng and Jiu Hong has led 5,000 elite cavalry less than ten miles away. We must take Zhangjiakou tonight! I hope that Manager Fan will cooperate in the city, and you and I will cooperate inside and outside, and we will definitely seize Zhangjiakou!"

Fan Yongdou quickly stood up, bowed to the ground, and gave a big gift: "Two lords, Caomin is naturally willing to help! There are 500 caravans guards from Caomin in Zhangjiakou City, and more than 200 people are left in Zhangjiakou, and the rest are in Datong, Beijing and other places; Caomin caravans guards are all dead soldiers. The two lords will come to attack Zhangjiakou, and Caomin can serve as internal supporters and seize Zhangjiakou in one fell swoop!"

The two Qing soldiers, Zhuangda, laughed, Dorolong stood up and patted Fan Yongdou on the shoulder: "Shopkeeper Fan, you are really a good servant of the Qing Dynasty! The Qing Dynasty has the power and will never forget the Fan family!"
