On the top of the mountain to the west of Shanhaiguan, it turned out to be where Weiyuan City was located. Wu Sangui looked at the familiar scenery in front of him and recalled the experiences during this period, and couldn't help but feel a lot of emotion.

Alas, after going around and fighting for years, I actually returned to the starting point.

He was the garrison of Shanhaiguan at the beginning. The Ming Dynasty fell and the capital fell. Chongzhen hanged himself, and people were in panic.

Originally, he had many choices.

He could choose to be loyal to the country and guard Shanhaiguan to the death. He could also choose to surrender to Li Zicheng, resist Jiannu, and help the Dashun Dynasty unify the world.

However, in the end, he chose to surrender to Jiannu because he found that the Ming Dynasty was already terminally ill, and even if it was still in Jinling, it was just a survivor. As for Li Zicheng, he was a bandit and could not accomplish any major events at all. Jiannu was scheming and expected to unify the world.

At first, his idea seemed to be correct. The Dashun Dynasty and the Hongguang Dynasty in the Southern Ming Dynasty were vulnerable. Jiannu was unstoppable and soon occupied a large area of ​​land in Shandong, Shanxi, Henan, Northern Zhili and Southern Zhili.

However, the sudden rise of Yongshengchao shattered his fantasy.

Jiannu was also vulnerable in front of Yongsheng Dynasty. Soon Nanzhili was recovered by Yongsheng Dynasty. Prince Yu Duoduo, King Jingnan Geng Zhongming and King Dingnan Kong Youde were both killed by the Crazy King.

Immediately afterwards, Shanxi and Henan were in a panic, Shandong was also conquered by Yongsheng Dynasty, and his old boss Hong Chengchou was also killed by the Crazy King.

At this time, the Regent Dorgon actually chose to retreat across the board and asked him to come back to guard Shanhaiguan!

To be honest, he really admired Dorgon's courage. There are so many lands in Shanxi, Henan and northern Zhili, and he will throw them away as soon as he says it, without any hesitation.

Perhaps, only such people can achieve great things.

Retreat to Shanhaiguan and Guanningjin defense lines is indeed the best choice, because whether it is to defend Kaifeng or the capital, the terrain is extremely unfavorable to them.

The Crazy King is known as a million-dollar army. Kaifeng and the capital are on the plains and are attacked from all sides. How could they survive?

Shanhaiguan is different.

This place is facing mountains and sea, with a narrow terrain, which is extremely unfavorable to the development of the army. Yongshengqiao's army had no choice but to attack from the southwest direction. Moreover, if it could invest more than 100,000 troops at a time, even if it was at the top of the sky, no matter how many people there were, they could only squeeze behind and wait.

Of course, it is very likely that people will play wheel battles, and more than one million troops will take turns to attack fiercely, which is quite scary.

Wu Sangui didn't know if he could withstand the revolving attacks of the Yongsheng Dynasty army. He could only try his best to strengthen the defense of Shanhaiguan. As for surrendering to the Yongsheng Dynasty, he couldn't even think about it. Geng Zhongming, Kong Youde, Hong Chengchou, Feng Quan and Xie Sheng were his role models. The madman probably hated the treason who had traitors. He caught it and killed it, and there was no sympathy to tell him.

He didn't want to stick out his neck to chop the madman.

Therefore, he had no choice but to guard Shanhaiguan.

However, Shanhaiguan is not as easy to defend as before. They already know how the Crazy King army attacked the city in Jinan City. That is to take advantage of the advantage of artillery range and flatten the city wall first. In this way, the city wall is like a decoration.

He also has to face this problem.

So, what should I do?

The range of the red-clothed cannon is not as far away as the cannon in the hands of the Crazy King. This is a problem that cannot be solved for the time being. He can only make a fuss about the geographical advantage.

The so-called standing is as high as you can see far, and placing the cannon on a high ground is also farther than shooting on a flat ground. Therefore, he decided to expand Weiyuan City, which is a few miles west of Shanhaiguan, and is located on the mountainside.

He decided to expand Weiyuan City into a sub-city that can accommodate tens of thousands of people and put most of the artillery on it.

As for why this is done, the reason is very simple, because Weiyuan City is on the top of the mountain, and it is extremely difficult to attack. If more than a hundred artillery pieces are installed, it will be even more indestructible.

More importantly, the cannons placed on the top of the mountain have a longer range than the cannons placed at the foot of the mountain. Even the cannons under the Crazy King's hand are about one mile longer than the red-clothed cannon. If they are placed at the bottom of the mountain where Weiyuan City is located, they will only be able to get shells.

In other words, with the terrain of Weiyuan City, it can completely offset the advantage of the artillery range under the Crazy King. As long as tens of thousands of people can be stationed inside, even if the Crazy King drives more than 100,000 troops to attack Weiyuan City, it will be useless.

After all, without the advantage of artillery, it can only be filled with human lives. Weiyuan City is on the top of the mountain, and it is difficult to lift the ladder up. The siege cars and well railings cannot be reached at all. More than 100,000 people go to attack such a strong city, which is to seek death.

As long as Weiyuan City is defended, Shanhaiguan’s pass will be guaranteed to be safe, because the cannons on Weiyuan City can completely cover Shanhaiguan City. Even if the Crazy King’s army flattened all the female walls and arrows in Shanhaiguan City, it would be useless.

As long as they dare to get close to Guancheng, they will have to be shot, and they are the kind of people who can't fight back by just being shot.

In this way, even if there are many people under the Crazy King, it will be fake.

Of course, it is not that simple to expand Weiyuan City on the top of the mountain into a city that can accommodate tens of thousands of people. It is even more difficult to transport hundreds or thousands of kilograms of red-clothed cannons.

Fortunately, he had 100,000 infantry under his command, and had a lot of people and strong power. Even if he built a city on the top of the mountain, he was not slow.

At this time, the only thing he was worried about was that before Weiyuan City was expanded, the Crazy King's army launched an attack.

Will the Crazy King attack Shanhaiguan?

Of course not.

At least, Zhu Qizhe would not attack Shanhaiguan at this time because it was completely unnecessary.

He could have used the advantages of the navy warships to transport the army directly to Liaodong to attack Shenyang, the Jiannu center, and kill Dorgon and Emperor Shunzhi in one fell swoop.

In this way, Wu Sangui became a masterless soul. He didn't even have to attack Shanhaiguan. He just blocked both ends so that Wu Sangui could not obtain food. At that time, the 100,000 troops guarding the pass would naturally collapse without fighting.

So what is Dorgon doing now?

To be honest, Dorgon also felt that he had returned to the starting point. After going around, he had returned to Shengjing after years of fighting.

But at this time, his young brother Duoduo had been killed by the Crazy King, and he also lost nearly 50,000 elite troops in the Eight Banners.

Such a blow was too great for him. You should know that the Eight Banners had only a total of more than 100,000 elite soldiers, and the loss was nearly 50,000 at once, and their combat power was equal to half.

Of course, he didn't have any gains.

At least, after occupying Northern Zhili, Shandong, Shanxi and Henan, they had enough money and food, and it would definitely be no problem to persist for a few years.

He has also thought about the planning over the past few years, which is to build artillery desperately!

He had realized the power of the cannons. To put it bluntly, the reason why they were beaten by the Crazy King army was that the number of cannons was not as large as that of others and the range was not as long as others.

This was not a big problem in his opinion, because they could cast artillery, but they had not tried their best to cast artillery before.

After suffering such a big loss this time, he naturally knew what to do.

Isn't it just a cannon?

It seems that no one can make it.

Isn't it just a long range?

I ordered people to cast a giant cannon of two thousand kilograms, with a range even further than you!
