In the Forbidden City, Wuying Hall.

Li Zicheng sat on the dragon throne, and his main civil and military officials stood on the lower side.

After receiving the letter of help from Emperor Chongzhen, Wu Sangui led his troops into Shanhaiguan to advance to the capital, but he completely stopped in Jizhou. Later, the capital was destroyed and Emperor Chongzhen committed suicide. Wu Sangui quickly withdrew his troops. Some of them retreated to Shanhaiguan, and most of them retreated to Yongping Prefecture on the west side of Shanhaiguan.

Because Wu Sangui did not lead his troops to retreat south with the crown prince Zhu Cilang, Li Zicheng felt that he had the will to surrender to him, so he did not immediately send troops to attack. Instead, he sent several batches of envoys to bring a large number of gifts, hoping that Wu Sangui would lead his troops to the capital to accept the adaptation.

Of course, Wu Sangui was unwilling to do so, but was frightened by the strength of the crusade army. He replied to Li Zicheng and said that he was willing to surrender, but said that some of his generals were dissatisfied and asked Li Zicheng to give him more time. He said it was delay, but in fact he took the opportunity to ask for a price and asked Li Zicheng to give him more promises and benefits.

Li Zicheng believed that Wu Sangui had no choice, and although he agreed to be appointed as a marquis and promised him to continue to command troops, in fact, there was not much real benefit to Wu Sangui.

The Qing army took action at this time, and Dorgon personally led tens of thousands of troops to directly hang out of Shanhaiguan, ending the dispute between Li Zicheng and Wu Sangui.

At this time, Li Zicheng no longer asked Wu Sangui to enter Beijing. Instead, he issued an edict to grant Wu Sangui the title of Zhendong Hou, asking him to lead his troops to guard Shanhaiguan against the Qing army. However, he proposed that he hoped to send a group of troops into Shanhaiguan to assist in guarding the pass.

Of course, Wu Sangui disagreed with this matter, saying that the troops in Shanhaiguan were sufficient, but they were short of food and food, so he asked Li Zicheng to provide some food and food.

Li Zicheng won Wu Sangui to agree to the matter. However, according to Li Yan's proposal, he was transported there in batches and multiple times, hoping to control Wu Sangui.

The Qing army did not launch a direct attack on Shanhaiguan, but helped Wu Sangui retain military power, but did not listen to Wu Sangui's private appeal. The offer to Wu Sangui was like King Sanshun, and he was granted the title of King Pingxi, and he could occupy a place and directly serve as his vassal in the capture of the world.

In other words, the Qing court offered Wu Sangui not to treat him as a subordinate, but as an ally to seize the world. It is hard to say whether he could be fulfilled in the end, but such conditions are inevitable that Wu Sangui will be moved.

People like Wu Sangui always leave room for themselves. Between the two major forces of the Chuang Army and the Qing Army, he had a good relationship with each other and negotiated, just to talk about better conditions for himself.

The situation inside and outside Shanhaiguan has not changed, but the external situation has undergone a sudden change.

The Qing army and Japanese coalition were defeated by Zhou Xian, and Luke Dehun was forced to abandon North Korea and withdrew back to Liaodong with the Korean royal family and hundreds of thousands of Korean people.

After hearing this, Dorgon did not blame Luke Dehun too much. He ordered Li Rutai to lead his troops to guard Phoenix City, and Luke Dehun led most of his troops to lead his troops eastward and continue to march towards Shanhaiguan.

North Korea's bitter and cold land is not worth the loss for a long time. Since Zhou Xian wants it, it doesn't matter if he lets him take it. If you restrain Zhou Xian's army in North Korea, can you take the opportunity to enter the Central Plains?

Dorgon also knew that the Qing army would have to face Zhou Xian's attack on both sides of Liaoning and North Korea. However, he felt that Zhou Xian's main enemy was Li Zicheng, and he would definitely not attack Liaodong at this time. As long as he was given time to defeat Li Zicheng and directly entered Shandong, Zhou Xian could only withdraw his troops from North Korea and South Liaoning.

Everything was planned well, so when Zhou Xian and Li Zicheng were discussing peace, and when Zhou Xian announced that he would only attack the Qing army within five years, he almost vomited blood directly, and the hatred for Zhou Xian was filled with the jar.

At this time, Dorgon had two choices.

One is to return to Liaodong and discuss peace with Li Zicheng, first defeating Zhou Xian with all his might, and then talking about others. The other is to send troops as soon as possible, defeat Li Zicheng as soon as possible, and occupy the Central Plains.

The result is self-evident, Dorgon chose the latter.

After all, Zhou Xian has such a choice, who can be sure that he will not surrender directly to Li Zicheng in the future? Then the Qing Dynasty will face the three-way attacks from Shanhaiguan, southern Liaoning and North Korea, and the situation will be even more difficult. The best strategy is to take advantage of Li Zi's establishment to defeat him without firmly, and then slowly deal with Zhou Xian.

Moreover, since Nurhaci entered the Central Plains, the Qing Dynasty has always been to seize the Central Plains. With such a good opportunity, with Dorgon's personality, how could he give up?

While sending people to order Haoge and Duoduo to speed up the dispatch of troops; while sending people into Shanhaiguan again, no longer trying to win over Wu Sangui, but instead scolded Wu Sangui to make a choice as soon as possible. For this reason, he brought red cannons from the rear and fired several cannons into Shanhaiguan every day to put pressure on Wu Sangui.

At first, Wu Sangui was not in a hurry and still delayed. It was not until the Qing army led by Haoge occupied Yulin and blocked the connection between the Shaanxi Break Army and the Shanxi Break Army. Another Qing army crossed the Great Wall and entered Shanxi, and the situation underwent a shocking change. Wu Sangui's attitude began to change.

You should know that there are currently hundreds of thousands of rebels in the capital, and their army is powerful. But after the Qing army occupied Yulin, the hundreds of thousands of troops were surrounded in the capital like a dumpling.

In the north, there was the Qing army led by Duoduo. In the west, there was the army led by Haoge. In the east, there was the Shanhaiguan defender led by Wu Sangui. In the south, there was the army led by Zhou Xian.

Enemies are everywhere.

Although Zhou Xian and Li Zicheng reached a peace agreement, everyone knew that the two did not trust each other. Seeing this situation, coupled with the excuses of Gao Qiqian and other generals, Wu Sangui finally decided to surrender to the Qing Dynasty. He let the Qing army enter the pass, quickly occupied Kaiping and moved to the west.

Dorgon made his own choice, and Wu Sangui also made his own choice, and then it was Li Zicheng's turn.

He now also faces two choices, whether to advance north or go east.

At present, half of Shanxi is still in the hands of the rebel army. If Duoduo can be defeated, expelled from Shanxi and Hebei. Then advance westward and take down Yulin, you can open up the connection between Shanxi and Shaanxi.

But there are many problems like this. Shanxi and Hebei are mountains on the north side, easy to defend and difficult to attack, and most of the Qing troops invaded there were cavalry. If they avoided fighting, it would be difficult to completely wipe out. Moreover, the north was famine, and the capital did not have much grain reserves. The road to the north was long and difficult to transport grain. If they could not win in a short time, the food and grass alone would directly drag down the rebel army.
