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

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

Fortunately, Wang Pu is a native of Datong, he is very familiar with the topography and landforms of Shanxi, and he is in a high position, so he has no big problem with his vision, so he can help Xu Changqing make some references and solve some problems.

Wang Pu had already thought about this matter, but frowned tightly, and thought for a while before saying: "Changqing, the terrain of Shanxi is complex and changeable, and there are many precipitous places that can be defended, but in recent years, the Shanxi soldiers have basically been disabled, and over the years, there are probably not a few people in Shanxi who have been in contact with the thieves...... What can really be defended is the two fortified cities of Taiyuan and Datong, I ...... It's really not recommended, let's enter the hinterland of Shanxi and fight with the thieves. At that time, if something goes wrong, it will be irreparable......

After suffering the loss of the Battle of Tongguan, Wang Pu was obviously more cautious when making a decision, and at this time, even if he gave up Laochao Datong, there was nothing difficult for him.

Xu Changqing nodded slowly.

In fact, Xu Changqing never thought of really entering the complex landform of Shanxi to fight a decisive battle with the exiled army, and there are many reasons for this.

The first and foremost problem is that food and wages cannot be preserved.

Moreover, within Shanxi, there are really too many unstable factors.

Historically, the main force of the northern front of the Exile Army, except for the desperate resistance of Zhou Yuji in Daizhou and Ningwu Pass, the others were almost in a no-man's land.

Although it was much better than the same period in history at this time, Xu Changqing's reputation in Shilin had always been bad, and once he entered the hinterland of Shanxi, it was difficult to guarantee that there would be no major changes if he was not familiar with the terrain and humanities.

This is a bit like Shi Dakai, the winged king of the Taiping Heavenly Kingdom, who marched into the Dadu River!

The idea is very good, but it ignores the general trend and human factors, and in the end, the success is successful, and a generation of heroes die with hatred.

The most important thing is that Shanxi is the control area of the Ming Dynasty, and the attack is only the main force of the Wandering Army, according to the structure of the Wandering Army, even if Xu Changqing can defeat this main force, in addition to losing his own troops, it is of little use, and they can pull up more manpower again.

If you want to solve the problem, the best way is to keep an eye on Li Zicheng and the core of the Exile Army!

As long as you can defeat the core of the Wandering People's Army and destroy their main organizational structure, even if there are still remnants of evil, it will be much simpler.

After thinking about it for a long time, Xu Changqing said slowly: "Don't they want us to do it?" Then, let's get ready to do it and take Tongguan! ”

"Huh?"

Wang Pu was stunned for a moment, and then came back to his senses, and his pupils dilated violently: "Changqing, what do you mean ......?"

……

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

"Huh?"

"Get it!"

"Yes!"

Tongguan City, these days of quietness, made Liu Fangliang from the beginning of nervousness, gradually to relaxed, and in the end, directly a little unimpressed.

After all, Tongguan is in danger, even if Xu Changqing is strong, it is still impossible to break through Tongguan from the front.

Not to mention, you wait for Liu Zongmin, who has already laid a net for Xu Changqing.

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

When Liu Fangliang finished reading it, his face changed, he squinted his eyes and looked at the east, and said fiercely: "A melon baby, isn't Xu Changqing quite clever, this time the brain let the donkey kick, and he really wants to play hard with us?" ”

"Shuai, right now, what should we do? Do you want to take the initiative and be ruthless. Fuck it, Lao Tzu has long seen that Xu Changqing's group of melon babies are not pleasing to the eye for a long time! ”

"Shuai Ye, you give the order, and you are willing to be a pioneer!"

Several generals around couldn't help but get angry.

These days, although they occupy Tongguan and rely on Qinchuan locally, they are even more stable in suppressing Xu Changqing in the general trend, but the model army's strong and powerful night blockade system makes them feel more aggrieved.

At the beginning, they could still go out of Tongguan Road to inquire about the outside news, but in the past few days, the model army has built a large number of fortifications at the pass of Tongguan Road, and there are many Western artillery to help, and they are fighting far and ruthlessly, and they can't go out at all.

In the past, when Xu Changqing was powerful, they could still endure it, but at this time, when the great power of heaven came, who the hell would endure this?

Looking at the passionate generals, Liu Fangliang was still very cautious, pursed his lips and said, "Don't worry!" Xu Changqing is a scheming person, let's take a look first, what he wants to do! Hehe, when Gao Ye and Yuan Zongdi's Northern Route Army moves, he will feel better! ”

……

"One, two, three, brothers, work hard! One, two, three, one more! ”

After August 15, it was already very cold.

Especially after a few days of autumn rain, the muddy and bleak autumn wind everywhere makes people feel colder than winter.

However, on several mountain passes on Tongguan Road, hundreds of sturdy men, all shirtless, sweating profusely, dragging huge artillery supported by wooden wheeled carts, pulled up the mountain with difficulty.

These days, the trees on the mountain have been cut down very much, and the whole mountain is bare, and even the mountain fires are difficult to burn again.

If it were in the future, I don't know how many environmental protection organizations and observation groups would come to Xu Changqing for trouble, but at this time, everything was cut off by Xu Changqing!

That's right.

Xu Changqing wants to build a fort here!

Moreover, not ordinary light artillery, but a strengthened version of the twelve-pounder redcoat cannon!

Several hills are connected, enough to build six forts, and it is no problem to build more than 20 red-coated cannons.

This time, as long as the thing is done, even if Xu Changqing can't capture Tongguan, the exile army will never want to fight it!

And as long as Xu Changqing doesn't leave, they will never want to come out of Tongguan Road!

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

On the top of a hill, a fort framed by rammed earth and gravel has been formed, standing at this angle, you can clearly overlook the whole picture of the surrounding ten or twenty miles, and you can clearly see the camp of the displaced army extending under the city of Tongguan without a telescope.

At this time, on the fort, a few white ghosts and more than a dozen artillerymen of the model army were nervously checking the final arrangement, just waiting for the sturdy Han people to pull up the red-clothed cannons and start debugging.

At this time, John Tang came here with a few entourages, laughing, and casually threw a small wine jug to the tall man named Paul.

Paul's eyes suddenly lit up: "Hey, Master Tang, it feels pretty good, at least, much better than Africa and Southeast Asia." ”

As he spoke, he sniffed the wine jug, took a big sip of joy, and praised: "This delicious Haicheng Laojiao is really a gift from God to mortals." It would be better if there were no such annoying rains. ”

John Tang laughed: "Paul, my friend, if you like it here." Go for it, you'll be pleasantly surprised. ”

After a few words of greeting with Paul, John Tang came to a higher rock not far away, took out a telescope, looked carefully near Tongguan, and took out a pen and paper from time to time to write and draw.

God pity you.

Rao is a person who thinks that Tang Ruowang has received a higher education, is well-informed, and has a strong imagination, but hearing a theory put forward by Xu Changqing this morning almost scared him to pee.

Can a human being fly in the sky like a bird?

Even, can fly to the top of this terrifying fortress and throw that terrible flowering bomb with manpower?

If someone had told him about it, he would have slapped it in the mouth, how could this be? That's not how the joke goes!

But when he understood Xu Changqing's train of thought and understood the principle, Tang Ruowang realized that this wise man was simply a genius!

As soon as he thought of this, in the future history books, he would mention his name and list himself as one of the inventors, John Tang was full of energy, and he didn't think much about it, and hurriedly calculated it.

"Boom!"

"Boom Rumble......

Not long after, the red-coated cannon on the hill was finally installed, and in a state of tune, Paul and the others also deliberately demonstrated, directly aiming at the direction of the camp of the displaced army.

Although it could not be hit that far, the huge sound of this 'boom' cannon, in the valley terrain, was like thunder, and the ears of the people who shook it buzzed, and the earth shook the mountains.

"Holy shit, what do you want to do? So far away, do they think the shells can hit our side?! ”

"Fuck it, the baby scared my grandfather, these model army melon babies, they all deserve to die!"

The exiled army in the battle array was relaxing, but they were suddenly awakened by the terrible sound of artillery, and the timid souls were about to be scared away, even if they were bold, they couldn't stop scolding.

It's fucking scary.

Compared with the outcasts, which have few artillery pieces, the model army is completely crushing in terms of equipment.

Even if their momentum at this time was far suppressing the officers and soldiers, but under this kind of subtlety, they couldn't help but start to have a fear of the model army.

Tongguan City.

Liu Fangliang held a monocular that he didn't know where to get it, and looked at the fort that the Model Army had gradually built not far away, and he only felt a chill in his spinal cord for a while.

Xu Changqing actually put on such a big battle, wasted so much effort, and flattened the mountain, and pushed such a heavy artillery onto the mountain, this is to play really.

Originally, Liu Fangliang thought that he had picked up a big bargain, so he dragged Xu Changqing and the model army on the side of Tongguan, and did not send troops, but he could reap the greatest merit.

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

Fortunately, Liu Zongmin was in Huayin not far away at this time, and after thinking for a while, Liu Fangliang waved his hand and beckoned his soldiers and said: "Go, immediately inform you of the matter, it is best to ask you to come and make a decision!" ”

"Yes!"

……

Early the next morning, Ruhou Liu Zongmin rushed over and carefully watched the layout of the model army opposite.

However, at this time, the Fort of the Model Army had already been blocked by many trees and branches, and it was impossible to see clearly for a while, even if it was a telescope.

Liu Zongmin was just about to criticize Liu Fangliang for making a big fuss.

"Boom!"

"Boom Rumble......

Suddenly, six forts on the mountain, more than 20 red-clothed cannons fired at the same time, and the mountain shook for a while, and the terrifying power was Liu Zongmin's courage, and he was almost scared to pee.

The sound of the cannon continued for more than ten minutes, and then it gradually stopped.

Liu Zongmin's face was already pale at this time, and his legs and stomach were a little weak.

Liu Fangliang naturally noticed Liu Zongmin's state, and hurriedly said carefully: "You wait, Xu Changqing is not good at that." He's spent so much effort here, I'm afraid, he's really going to end up with us......"

Liu Zongmin gasped, and it took a long time to recover, and said coldly: "Xu Changqing is a dog thief, he is really a thief!" I'm afraid that he won't pay attention to Shanxi at all, and he is still staring at our Xijingna! This matter must be notified to the emperor immediately! ”

Whether it is a veteran general, even if there was a slight gaffe at the first time, Liu Zongmin did not mess up, and quickly reacted and made the right decision.

This is also a strong talent of people, acquired, it is difficult to work hard and learn.

At this time, a correct judgment is more important than anything else!

Although Liu Fangliang is also a veteran, it took a long time to come back to his senses: "You wait, no, won't you?" Could it be that Xu Changqing really dares to risk the world's disapproval, ignore Shanxi, and be tough with us in Tongguan? ”

"Huh."

Liu Zongmin suddenly sneered: "The bird's ambition to know the bird? Don't take the thoughts of those ants to speculate on the thoughts of a hero like Xu Changqing! Lao Liu, in the past few days, you have worked harder to make your defenses more stable! The day after tomorrow, the emperor must supervise the war! This battle, perhaps...... It will be directly related to the life and death of our Dashun! ”
