If you want to say who is most worried about the pressure of the army, it must be the soldiers and generals guarding the border passes, as the front-line personnel, they must be the first to be impacted.

Hou Jin put out a formation of hundreds of cannons to suppress Wu Sangui, if it weren't for the power of the cannonballs too weak, not compared with the Australians, I'm afraid the city would have been breached long ago.

It cannot be said that the gunpowder power of Houjin is too weak, the gunpowder of the whole world in this period is made of black powder, and the power of black powder naturally cannot be compared with yellow powder, not to mention the original production method adopted by Houjin.

The cannonballs hit the city wall one by one, although the city wall of Shanhaiguan is thick, but it also caused a lot of damage, Dolgon does not seem to have the intention of withdrawing the army, it is about to enter the winter, this Liaodong is cold, it is estimated that it is to fight the autumn wind.

However, this time the autumn wind is a little different, swinging hundreds of cannons to fight like this, when has Jin been so extravagant after this, this formation will only do this when attacking the city, and it will not be at all at other times.

Wu Sangui fell into thinking, thinking about how to solve this problem, to say that the Guanning Iron Cavalry under his command and the Houjin army could not be defeated, but the key was that he had no rear support, and the imperial court had no reinforcements and supplies, and once he attacked, he would definitely die.

So Wu Sangui didn't want to send troops, Wu Sangui's defection to the enemy in history was largely caused by Li Zicheng, because his family in Beijing was killed by Li Zicheng, so he led the Qing army into the customs to fight against Li Zicheng, not because of Chen Yuanyuan in the TV series.

Wu Sangui is also a generation of heroes, how could he do such a thing because of his children's affection, it is just a fabrication made up by wild historians in order to increase the interest of reading.

The Ming defenders of Shanhaiguan, who had no reinforcements, confronted each other without sending a single soldier in the midst of Dolgon's constant provocations.

Neither side sent troops easily, Dolgon was just tempting, but he knew that Wu Sangui was an extremely ambitious guy, if you want to say that this guy is heartfelt, then you are absolutely wrong. This guy is not really sincere, if he is really sincere, he will not let the Qing army in the future in the general interests of the nation.

So what is certain is that he actually has ideas, born in troubled times, and he is a general who supports the army and respects himself, so he must have some ideas. How can it be possible without ideas, there are only a few teams in the Ming army that can fight, and the combat effectiveness of the Guanning army can be said to be the number one in the ranks.

A leader of a force who can confront the Houjin army and does not care about the general situation of the world is absolutely unreasonable, and it can even be said that he is not a very good leader.

Although Wu Sangui is on the frontier, he also has his own eyeliner in the capital and other places to collect intelligence for him, and he knows what the situation in the imperial court is now. It can even be said that he has concluded that there are no reinforcements in the imperial court.

This is not the most rare for the defenders of the frontier, the most difficult thing is the supply of materials, it is difficult to hold on without materials, this is the current situation, it can be said that the imperial court did not allocate materials, but at all.

Although it is possible to survive for a period of time by relying on the materials hoarded in previous years, it is absolutely impossible to survive for a long time, for the ambitious Wu Sangui. He also only observed the situation of Da Ming, and he could feel that Da Ming's qi was exhausted. There is no way back.

So when resisting Houjin, he paid great attention to preserving his strength, and on the other hand, he asked the eyeliner in the inland to pay attention to Li Zicheng's movements, at present, Li Zicheng is very likely to enter Beijing, according to his analysis, Li Zicheng's army's next biggest target is Beijing.

Once Li Zicheng entered Beijing, it would also mean the beginning of a change of dynasty. He, a general soldier with hundreds of thousands of troops, will inevitably be co-opted or appeased, and it is possible to tear the earth and seal the marquis, because everything is in front of him.

Secretly reserve strength and wait for Li Zicheng's appeasement, this is Wu Sangui's plan. As long as you hold the Guanning Iron Horse, you will have your own place to survive in this troubled world.

Although the army of the Later Jin seems to be strong, in Wu Sangui's opinion, it is still difficult for them to enter the Central Plains, after all, it is difficult for foreign rule to last for a long time, and the Mongols are a lesson from the past.

If he could, he would like to give Dolgon something to withdraw, and such a confrontation here is not a good thing for both sides.

Of course, Wu Sangui may not know that the other party is just a temptation, and he has no intention of confronting him for a long time, and if the confrontation continues, Houjin himself will not be able to stand it.

So Wu Sangui can be said to have thought too much, but he didn't know that people just wanted to test fire artillery, and they just happened to find him.

Dol Roll did come to test fire artillery, but he didn't think that Wu Sangui would send someone to negotiate with him.

Since the other party has sent a messenger, let's see what the situation is saying, and after understanding, Wu Sangui hopes that the other party will withdraw his troops, and is willing to give some money, food and winter items.

This made Dolgon a little surprised, but he didn't expect that just a position was made for the other party to obediently send money and food, which was simply too happy.

Dolgon didn't rush to agree, but offered his own price, since Wu Sangui could use money to eliminate the disaster, he must have been prepared, so he couldn't agree so easily, he had to knock on a bamboo pole.

Originally, Wu Sangui's price was to send 100,000 taels of silver, and a few pieces of cotton cloth for the winter, which was definitely very feudal in terms of quantity, but from another aspect, this was Wu Sangui begging for himself.

Therefore, Dolgon asked for 300,000 taels of silver, and the materials and other requirements were doubled, which made Wu Sangui tremble with anger, if he didn't want to preserve his strength, how could he negotiate with you Tatars.

However, the problem that money can solve is still solved by money, once Li Zicheng is appeased, Wu Sangui will be able to make up for all today's losses from the other party, and if he figures it out, he will not be so angry.

Dolgon didn't expect Wu Sangui to agree so quickly, and he didn't even say any conditions, thinking that since the other party agreed, it would not be easy for him to regret what he promised, so he finally agreed to withdraw the army.

It can be said that the materials and money given by Wu Sangui this time are an unexpected gain, and even Dolgon wondered, if he came a few more times, could he still get the same treatment, but Wu Sangui definitely didn't want to see him, and the materials this time could be said to be solved by him out of his own pocket.

He is betting on Li Zicheng, waiting for the other party to appease him, and then earn the money back, but how did he know that Li Zicheng will have a life-and-death duel with him in the end, which will directly affect the history of the next few hundred years. (To be continued.) )
