Compared with Shaanxi, which is steep outside but flat inside, the terrain of Shanxi is more complex and varied.

Xu Changqing had already begun to make a "sand table" at this time, but it would take time to explore all the surrounding terrain.

Fortunately, Wang Pu is an indigenous person in Datong. He has a very good understanding of Shanxi's terrain and landform. He is in a high position and has no big problems with his vision. He can help Xu Changqing to provide some references and solve some problems.

Wang Pu had thought about this matter for a long time, but frowned and thought for a while before saying: "Changqing, Shanxi's terrain is complex and changeable, and there are many steep places to defend. However, in recent years, Shanxi soldiers have basically been destroyed. Moreover, in recent years, there are many powerful people in Shanxi who have contact with the bandits... The only ones that can be defended are the two strong cities of Taiyuan and Datong. I... I really don't recommend that we enter the hinterland of Shanxi and fight with the bandits. At that time, if something goes wrong, it will be irreversible..."

After suffering the loss of the Battle of Tongguan, Wang Pu was obviously more cautious when making the decision. At this time, even if he gave up his old nest, he would have no trouble.

Xu Changqing nodded slowly.

In fact, Xu Changqing never thought of actually entering the complex landforms of Shanxi to fight the decisive battle with the refugee army. There are many reasons for this.

The first thing to bear is that food and wages cannot be preserved.

Moreover, there are too many unstable factors within Shanxi.

Historically, the main force of the northern front of the refugee army, except for Zhou Yuji's desperate resistance in Daizhou and Ningwu Pass, was almost in a state of no one.

Although it is much better than the same period in history at this time, Xu Changqing's reputation in Shilin has always been poor. Once he enters the hinterland of Shanxi, it is difficult to guarantee that there will be no major changes when he is unfamiliar with the terrain and humanities.

This is a bit like Shi Dakai, the wing king of the Taiping Heavenly Kingdom, who entered the Dadu River!

The idea is very good, but he ignores the general trend and humanistic factors. In the end, his success failed and a generation of heroes died in hatred.

The most important thing is that Shanxi is the control area of ​​the Ming Dynasty, and it is only attacking a main force of the refugee army. According to the structure of the refugee army, even if Xu Changqing can defeat this main force, it will be of no use except for causing himself to lose troops and lose generals. They can raise more people again by laughing and relaxing.

If you want to solve the problem, the best way is to keep a close eye on Li Zicheng and the core of the refugee army!

As long as it can defeat the core of the migrant army and destroy their main organizational structure, even if there are still remaining remnants, it will be much simpler.

After thinking for a long time, Xu Changqing said slowly: "Don't they want us to do it? Then, we are ready to do it and take down Tongguan!"

"Forehead?"

Wang Pu was stunned, and after a moment of recovery, his pupils suddenly magnified: "Changqing, what do you mean..."

...

"Master, the latest battle report ahead, Xu Changqing has made moves!"

"Um?"

"Take it over!"

"yes!"

At the beginning of Tongguan City, the quietness of these times made Liu Fangliang gradually relax from the beginning to the relaxation, and finally, he was a little distracted.

After all, Tongguan has natural dangers in hand. Even if Xu Changqing is strong, it is still impossible to break through Tongguan from the front.

Not to mention, your husband Liu Zongmin has already set up a net of heaven and earth for Xu Changqing.

But today Liu Fangliang was basking in the sun on the city wall, but suddenly received a war report from the front!

When Liu Fangliang finished watching, his face changed. He squinted his eyes and looked at Dongfang, and spat fiercely: "A melon baby, isn't Xu Changqing very smart? This time he was kicked by a donkey. He really wanted to play hard with us?"

"Shuai, what do we think of now? Should we take the initiative to attack? Fuck him hard? I have been disliked by Xu Changqing's group of melon boys for a long time!"

"Shishuai, please give me the order, I am willing to be the pioneer!"

Several generals around couldn't help but get angry.

During these days, although they occupied the natural danger of Tongguan and were backed by Qinchuan, they suppressed Xu Changqing steadily in the general trend, but they can demonstrate the powerful and powerful blockade system of the night without closure.

, let them feel so frustrated.

At the beginning, they could still go out of Tongguan Road to find out the news outside, but in the past few days, the Model Army has built a large number of fortifications at the gate of Tongguan Road, and has many Western artillery to help. They are fighting far and ruthlessly, so they can't get out at all.

In the past, when Xu Changqing was powerful, they could bear it, but at this time, the power of Dashun Tian came, who would still bear it?

Looking at the passionate generals, Liu Fangliang was still very cautious and pursed his lips and said, "Don't worry! Xu Changqing is a man of tricks. Let's take a look first. What he wants to do! Haha, when the Gao Ye and Yuan Zongdi's Northern Army move, he will feel better!"

...

"Yi23, brothers, work harder! Yi23, let's do another one!"

After August 15th, it was already very cold.

Especially for several consecutive days of autumn rain, the muddy and bleak autumn wind everywhere, making people feel that it is only colder than in winter.

But at several mountain passes on Tongguan Road, hundreds of tough men were shirtless, sweating profusely, dragging huge cannons supported by wooden wheels and pulling them up the mountain with difficulty.

During these days, the trees on the mountain have been cut down very well. Looking at me, the whole mountain is bare, and even the wildfires are difficult to burn again.

If it were in later generations, I still didn’t know how many environmental protection organizations and observation teams would come to cause trouble for Xu Changqing, but at this time, everything was decided by Xu Changqing!

That's right.

Xu Changqing is going to build a fort here!

Moreover, it is not an ordinary light cannon, but an enhanced version of the twelve-pound red cannon!

Several hills are connected together, so it is enough to build six turrets, and there is no problem with building a dozen red cannons.

This way, as long as things are done, even if Xu Changqing cannot conquer Tongguan, the refugee army will never be able to fight!

And as long as Xu Changqing doesn’t leave, they will never think of coming out of Tongguan!

"Hi, Paul, my friend, how do you feel?"

On a mountain, a fortress made of rammed earth and gravel has been formed. From this angle, you can clearly overlook the full view of more than ten or twenty miles around. You can clearly see the refugee military camp extending under Tongguan City without a telescope.

At this time, on the fort, several white ghosts and more than a dozen model army artillery soldiers were nervously checking the final arrangements, waiting for the fierce Han people to pull up the red-clothed cannons and start debugging.

At this time, Chau Wang came here with a few followers and smiled, and threw it to the tall man named Paul a small wine pot.

Paul's eyes lit up: "Hi, Tang Ye, I feel pretty good, at least, much better than Africa and Southeast Asia."

As he said that, he smelled the wine pot, took a big mouthful of joy, and praised: "This delicious Haicheng Laojiao is really a gift from God to the mortal world. It would be even better if it weren't for these annoying rain."

Johnson Chan laughed: "Paul, my friend, it's good that you like this place. Come on, you'll be surprised."

After a few greetings with Paul, Tang Ruowang came to a higher rock not far away, took out his telescope, looked carefully at the near Tongguan, and took out his paper and pen from time to time to write and draw.

God is pitiful.

Even though Joshua Tsang thought he had received higher education, was well-informed and had strong imagination, he almost scared him when he heard a theory proposed by Xu Changqing this morning.

Can humans fly in the sky like birds?

Even, can you fly to this terrifying fortress and throw that terrible flowering bullet with human power?

If someone told him about this, he would have slapped him with a mouth. How could this be possible? The joke wasn't like this!

But when he understood Xu Changqing's ideas and the principles, Joshua Chan then realized that this Ming Dynasty powerful man was simply a genius!

When I think of this, in future history books, I will mention my name and list myself as one of the inventors. Chau Wang was full of energy and no longer thought about it. I was busy.

(This chapter is not finished, please turn the page)

Calculate quickly.

"boom!"

"Boom..."

Soon, the red cannons on the hill here were finally installed. In the mode, Paul and others also deliberately demonstrated, directly aiming at the direction of the refugee military camp.

Although it can't be that far, the huge "rumbling" cannon sound was like thunder in the valley terrain, making people's ears buzzing, and the earth shaking.

"Damn it, what do these miscellaneous people want to do? So far away, do they think the shells can hit us?!"

"Damn it, the baby was shocked. These model army's melons should be damned!"

The refugee army in the battle formation was relaxing, but suddenly woke up by the terrible sound of cannons. The timid soul was about to be scared away. Even those who were brave could not stop cursing.

So fucking scary.

Compared with the refugee army, which had few guns, the model army was completely crushing in terms of equipment.

Even if their momentum was far suppressing the official army, they couldn't help but become afraid of the model army in this subtle way.

On the top of Tongguan city.

Liu Fangliang held a monocular telescope that he had bought from somewhere. Looking at the turret that the Model Army had gradually built up not far away, he felt a chill in his spinal cord.

Xu Changqing actually made such a big battle, wasted such a great effort, and almost leveled the mountain. Such a heavy cannon was pushed to the mountain. This is really a real thing.

Originally, Liu Fangliang thought he had taken a big advantage, so he dragged Xu Changqing and the model army at Tongguan. Without sending troops, he would be able to gain the greatest achievements.

But at this time, he had realized the seriousness of the problem. Xu Changqing was really going to take the Tongguan surgery...

Fortunately, Liu Zongmin was in Huayin not far away at this time. After thinking for a while, Liu Fangliang waved his hand to greet his personal soldiers and said, "Go, notify your husband immediately. It is best to ask your husband to come and make a decision!"

"yes!"

...

Early the next morning, Ru Hou Liu Zongmin rushed over and carefully watched the arrangement of the model army opposite.

But at this time, the model army's fortress had long been blocked by many trees and branches, and it was impossible to see clearly for a while, even if there was a telescope.
To be continued...
