Leave 100,000 troops to Zu Keyong to garrison the Beijing Division, and Lin Yi personally commanded the army of 100,000 troops to Shanhaiguan.

Lin Yi led these 100,000 horses, most of which were elite divisions, including the standard battalion, the invincible battalion, the musket battalion, the guard battalion, the women's battalion, the artillery battalion, and the logistics grain and grass supply battalion. There are infantry and cavalry, and the arms are complete.

These are his descendants, and the troops account for 70,000.

In addition, there are 30,000 Fengyang soldiers and Henan soldiers, Ma Shiying, the governor of Fengyang, and Yuan Shu, the general soldier of Henan, who went out with the army to listen to the army.

Before leaving, the large and small government affairs in Beijing were temporarily handed over to Jiang Riguang, Shi Kefa and Lu Daqi, Jiang Riguang is known as a virtuous minister, Shi Kefa's ability is needless to say, his loyalty can be described by the four words "Shi Xin Kefa" of later historians, as for Lu Daqi, it is synonymous with uprightness, and the military affairs in Beijing were handed over to Zu Keyong.

On the day that Lin Yi's team left the Beijing Division, the crown prince Zhu Cihong took a hundred officials led by Jiang Riguang, Shi Kefa and Lu Daqi out of the city to see them off.

100,000 horses under the banner of the Ming Dynasty left Beijing and headed for Shanhaiguan......

Shanhaiguan is worthy of being the world's first male pass, lying on the shore of the Bohai Sea, the Great Wall is like a dragon, and Shanhaiguan is like the dragon's head.

There are two customs cities in it, one is Shanhaiguan, and the other is a Shiguan city belonging to Shanhaiguan. These two gates are about forty miles apart, and a stone pass city is named because there is a mess of stones outside the pass.

A piece of Shiguan City and Shanhaiguan echo each other, guarding these two Guancheng, this generation of the Great Wall is like an iron wall, indestructible.

Now stationed in this gate is Pingxi Bo Wu Sangui, who was sealed by Chongzhen during his lifetime.

However, as early as more than a month ago, Wu Sangui also received an edict from the crown prince, that is, Li Zicheng had just invaded Yanjing, and Emperor Chongzhen had just hanged himself, and this edict was of course drafted according to Lin Yi's intentions.

In the edict, the prince told him that although the Jingshi was broken by thieves, and although Emperor Chongzhen was also martyred, there was still the prince, and Lin Yi's army of more than 100,000 people, as well as the kings of the Ming Dynasty and a group of loyal old ministers, and the Ming Dynasty would never lose the country, so Wu Sangui hurriedly led his troops to King Qin.

After reading this edict, Wu Sangui suddenly fell on the table and sneered: "What kind of prince's edict is manipulated by the surname Lin, what does a 15-year-old kid know!" He also wants to use the prince to coerce the world, and he wants to be beautiful! ”

"Uncle, what are you going to do?" General Ma Baodao.

Ma Bao is just 20 years old this year, this is Wu Sangui's confidant, and he is also his right-hand man. According to the original historical development, after Chong Guan was angry and became a red face, Wu Sangui surrendered to Dolgon, introduced the Manchu Tartars into the country, and then became a pawn for the Manchu Tartars, chasing the remnants of the Dashun Army and the Ming Dynasty and the anti-Qing forces, Ma Bao later became his son-in-law, in the era of the Kangxi Emperor, Ma Bao assisted Wu Sangui to create the Kangxi rebellion, and raised the banner of the anti-Qing Dynasty and the restoration of the Ming Dynasty, known as the rebellion of the three feudatories, at that time Ma Bao, who was a civil and military all-rounder, was Wu Sangui's generalissimo, and now Ma Bao is still a young man in his early 20s, But his outstanding military talent and strong martial arts have won Wu Sangui's favor.

Wu Sangui rolled his eyes and said: "Immediately reply to the prince, just say that we responded to the prince's call, but we can't draw soldiers and horses to the king, because the Tartars outside the gate are eyeing the king, if you lead the troops to the king, the Tartars will take advantage of the situation, let the surnamed Lin and Li Zicheng fight, consume each other, and the two will be defeated, and then we will send troops again and destroy the two of them."

"Uncle is so tall." Ma Bao said that he ordered someone to take a pen, ink, paper and inkstone, Wu Sangui personally picked up the pen in his hand, thought a little, and replied to the prince with a letter.

But soon after the letter was sent, Wu Sangui's wishful thinking fell through. Because he soon got the report, Li Zicheng personally commanded the army of 100,000, with Niu Jinxing as the military advisor, let Liu Zongmin as the front, and 100,000 Dashun troops came to Benshanhaiguan.

Wu Sangui was stunned at first, and then he gritted his teeth: "It's good to come, Li Zicheng, Liu Zongmin, the hatred of killing your father, the hatred of taking your wife, you don't share the sky, I, Wu Sangui, want to settle a general account with you this time!"

Wu Sangui thought of his beloved concubine Chen Yuanyuan, and couldn't help but get angry in his heart, and split the table in half with a click.

He immediately ordered the general Ma Bao to lead 10,000 troops to garrison a piece of Guancheng, and Wu Sangui personally commanded an army of 40,000 troops to garrison Shanhaiguan.

A few days later, Li Zicheng commanded the Dashun army to reach the bottom of the two cities, 100,000 Dashun troops, black pressure lined up for dozens of miles, outside the Shiguan City and Shanhaiguan City, all of them were the men and horses of the Dashun army.

There are also 200 red-coated cannons, and they have also found positions outside the city, and their soldiers have begun to deploy red-coated cannons.

However, Li Zicheng did not attack the city, but took Liu Zongmin, Niu Jinxing and others to the bottom of the city, and asked Wu Sangui to answer the city.

Half an hour later, Wu Sangui really appeared at the head of the city, followed by the general Ma Bao and other subordinates.

Li Zicheng, who only had one eye and worked, persuaded Wu Sangui to surrender, as long as he was willing to submit to Dashun, he could talk about anything, he wanted land for chassis, women for women, gold and silver jewelry for gold and silver jewelry, and official positions for official positions, which could meet all his conditions.

Li Zicheng said very politely, saying that there was some misunderstanding between them, and Wu Sangui was lifted to the sky.

How do you know that Wu San sneered, saying that he Wu Sangui didn't want anything, and it was okay for him to surrender, as long as Li Zicheng gave Gao Guiying to him and Liu Zongmin's wife to him, he would surrender Dashun unconditionally.

Now Li Zicheng is annoyed, he can do anything, but Wu Sangui prefers his wife Gao Guiying, so what can he do? Gao Guiying is now the queen, and Li Zicheng is now the emperor of Dashun, and he can't give up the queen no matter what.

This is Liu Zongmin's wow-wow-wow-wow, and he immediately ordered the siege of the city.

The Dashun army rushed towards Guancheng like a tide, and the red-coated cannons also fired.

Wu Sangui ordered his soldiers to return fire, muskets, bows and arrows, and red-coated cannons, and the ground shook for a while, sand and stones splashed, flames soared, and casualties were everywhere.

The two sides fought for three days and three nights, with casualties on both sides.

Although Li Zicheng has many people and horses, Wu Sangui's people and horses are only half of Li Zicheng's, but he is stubbornly defending the dangerous city, and a piece of stone echoes with Shanhaiguan.

Li Zicheng's men and horses could not be attacked for a long time, the wounded soldiers were damaged, and Liu Zongmin was also wounded by arrows, so Li Zicheng had to retreat for the time being.

Liu Zongmin's arrow was taken out, after bandaging the wound, Li Zicheng and Niu Jinxing were discussing with Liu Zongmin how to break through the Shanghai Customs, at this time the bad news came, Li Yan failed to rescue Gao Yigong, the siege of Gaobeidian was not solved, 100,000 Dashun troops were annihilated, Lin Yi used a deceptive city plan, and the Ming army broke through Beishang Beijing overnight.

When Li Zicheng heard this, he almost fell off his horse, Niu Jinxing and Liu Zongmin were also stupid, and they didn't speak for a long time.

In any case, they can't believe that Beishang Jing has gained and lost so quickly? Gao Guiying, Li Yan, Li Guo, Liu Fangliang, Yuan Zongdi, all brave and good at fighting, both civil and military, as well as military advisors Song Xiance and Li Yan, are resourceful, with more than 200,000 horses under their command, why can't they deal with a Lin Yi, why can't they even lose the Beijing Division?

Li Zicheng thought of Gao Guiying and Dou Meiyi, and Liu Zongmin also thought of Chen Yuanyuan and his wife Huang, and the two decided to retire.

Niu Jinxing also agreed to the plan to withdraw the troops, but in front of him, Shanhaiguan could not be taken, and tens of thousands of soldiers and horses were lost, and Beijing was lost again, and the battle was too unsmooth.

But at this time, Wu Sangui sent someone to deliver a letter, and Li Zicheng opened the letter and looked at it, and he was stunned.

The letter was written by Wu Sangui himself, Wu Sangui said in the letter that Lin Yi was a traitor of the Ming Dynasty, holding the prince hostage and indiscriminately issuing orders, and he needed to use Li Zicheng's hand to clear the monarch's side, and he hoped to cooperate with Li Zicheng and let Li Zicheng help him, and the previous affairs of the two of them were eliminated.

Li Zicheng read the letter three times, and then handed it to Niu Jinxing and Liu Zongmin, these two people were also a little stupid after reading it, and Wu Sangui's attitude immediately changed, which caught them off guard and confused.

They asked the sender, and the sender told them that their uncle Wu Sangui and Lin Yi had long had a grudge, and if Dashun could join forces with him to deal with Lin Yi this time, they would be willing to give up a piece of Shiguan City to show their sincerity, and the grievances between the two of them would be written off and not mentioned again.

Li Zicheng, Niu Jinxing, and Liu Zongmin discussed and felt that this matter was feasible, and negotiated repeatedly with Wu Sangui, and after the two sides reached an agreement, Wu Sangui ordered Ma Bao's people to withdraw, and Li Zicheng led the Dashun army into a Shiguan City.
