This time, the soldiers of the new auxiliary army did not stop far behind like last time. Instead, they followed the civilians and marched to 200 meters before they stopped and set up a shield formation. The civilians were filling in the trenches in front, while they cowered. Supervising the battle behind the giant shield formation. In order to prevent being hit by artillery, they all wore armor this time. Different from the uniform leather armor of the Mongolian cavalry shooters, these armors were pieced together by the newly attached soldiers in the entire battalion. There were also leather armors, and the most common ones were paper armors equipped by the Song Army. Seeing that the civilian laborers kept coming to fill the trenches, Cao Ergou ordered the soldiers of the Pili Army to shout and persuade, trying to get the civilian laborers to flee to the mountain pass. Only this time, No matter how they shouted from the wall, the civilians refused to run away anymore. Although their faces turned pale with fear, they no longer cowered and started filling the trenches with all their strength. What the soldiers of the Perak Army did not know was that filling the trenches The reason why the civilian husbands did not escape was not because they did not want to but because they did not dare. In order to prevent escape, the civilian husbands brought by the new annexed army this time were carefully selected. One of them was selected from the father, son or brother in the camp, and the other Then they stayed in the rear camp to work. If one escaped, the other would be killed on the spot. Not only did the chosen civilians not dare to escape, but they also worked extremely hard because the Mongols promised that as long as the trenches were filled up, Then you can work with your loved ones in a safe rear area.

Cao Ergou saw that shouting was useless, and saw the soldiers of the new annex hiding behind the giant shield and shouting to supervise the battle. In anger, he ordered the artillery shells to be replaced by solid bullets and fired at the giant shield formation. After the new annex army was shelled last time, I found that the injuries of the unarmored ones were much more serious than those of the armored ones. I even found a lot of bullets the size of beans and wheat stuck in the armor and shield without damaging the body, so I started to think carefully. The armor on my body was tall and thick. The huge shield gave the newly attached soldiers a high sense of security. However, with the sound of cannons on the city head, their sense of security became an illusion. Fiery solid bullets flew in, easily smashing the shield. Lu's giant shield and body rolled forward with the burnt smell lingering.

When the civilians saw that the soldiers from the new auxiliary army who were supervising the battle in the rear were shattered on the ground, they fled back to the camp. However, they were driven back not long after they fled back. The new auxiliary army who was supervising the battle this time still stopped at the camp. Two hundred meters away, but they did not carry giant shields, but human shields - a large number of civilians stood beside them. After two rounds, these devils understood a truth, that is, the Perak Army defeated the civilians. He is truly a human being and will not be hurt easily.

The newly attached army drove some civilians to fill the trenches, and some civilians dug trenches on the spot at the supervising battle site. After the trenches were dug, a large number of logs were transported from the rear to build a fence. After the fences were erected, they began to dig soil. Cao Ergou watched He couldn't give the order to fire bombs on the civilians. In desperation, he sent people back to Wanjiaping to ask Ouyang Xuan for instructions. Before the Mongols invaded, Ouyang Xuan moved the defense across the board. The mission of the original fort was fully entrusted to Cao Ergou, and he stayed in Wanjiaping. On the one hand, Cao Ergou was much better than himself from a tactical perspective, and staying in Wanjiapu would interfere with the command. On the one hand, the scientific researchers of the institute are still waiting for his guidance. They are currently trialling the production method of glass. In response to Cao Ergou's request for instructions, Ouyang Xuan only replied with four words: "It's cheap."

After receiving the reply, Cao Ergou discussed with his company commanders for a long time and decided that they could no longer allow the civilians to fill the trenches. Since the civilians did not listen to the instructions, the Pili Army did not need to be polite. However, Cao Ergou did not kill him.

It was an order to hit them with small stones. Although these civilians were hit with bruises and swollen faces, they still did not stop. They did not dare to stop because the Mongols had already said that if they failed to complete the task, all their relatives detained in the camp would die.

Cao Ergou thought in his mind that if the war supervisor team was not dealt with, the civilians would not dare to retreat. At this time, 200 meters away, a row of long log fences had been formed where the new auxiliary troops of the war supervisor were hiding, and the personnel could be vaguely seen behind it.

Keep moving. When the civilians were erecting the fence, Cao Ergou did not order the artillery fire. Because of the technical constraints, the Pili Army's artillery was unable to fire at this time.

Hitting the target is quite good, but it is impossible to accurately hit the new auxiliary troops supervising the battle without hurting innocent civilians. Although the logs of the fence are as thick as the mouth of a large bowl and cannot be destroyed except by large-scale siege weapons, they are really powerful in the face of solid artillery shells.

It's not really strong. It's just that we have to ensure the safety of Hengyuan Fort but don't want to accidentally injure the civilians. It's really a dilemma. If the civilians are allowed to

This soil work will put Hengyuan Fort in danger, and the loss of Hengyuan Fort will put tens of thousands of people in the mountains in danger. At this moment, artillery bombardment has to be launched. Didn't Brother Xuan say, "It's necessary

Is there such a saying as "Thunder tactics, but also the heart of a Bodhisattva"? Although Buddhism says that all living beings are equal, the Mongolian soldiers are demons, and the soldiers of the new annexed army are

They were extremely vicious accomplices. Although these civilians were coerced, they also posed a threat to the Perak Army. They almost filled up the trenches and built wooden fences as long as the south side of Hengyuan Fort. For the sake of the Perak Army soldiers and the mountain

The safety of the people was too much to worry about. Cao Ergou sighed heavily and issued an order: "Blow down the wooden fence."

A row of solid bullets came over, and the wooden fence was blown to pieces, with fragments flying everywhere and wailing sounds. The civilians who were filling the trench also turned around and fled. However, after the smoke passed, Cao Ergou discovered that although the wooden fence had been blown down, it was still intact.

A thick earthen wall was exposed. It turned out that the new annexed army drove a large number of civilians to join them, not just to use them as human shields, but to dig and build earthen walls. The wooden fence was not used to defend against artillery fire, but to cover it.

Blocking the line of sight in order to secretly build earthen walls. Although these earthen walls were built in a hurry and some parts were not yet completed, their defensive effect against artillery was better than walls made of stone. Because the earth used to build the walls was thick and moist,

, many artillery shells were just embedded in them, and only the solid shells of heavy artillery could penetrate them. The shivering new annex troops hiding behind the wall were not hit by many shells, and most of the casualties were injured by the fragments of the fence flying around.

Seeing that the earthen wall could deal with the Pili Army's artillery, the new annexed army no longer drove the civilians to fill in the trenches - which was almost done, but drove the civilians to build and strengthen the earthen walls. The Mongols certainly did not do this for no reason.

There will probably be a big move next. Thinking of this, Cao Ergou felt a little bit.

Panicked, he ordered the earth wall to be bombarded. It was said that although the earth wall was thick, it would definitely not be able to withstand concentrated fire and artillery fire. It only needed a few hits to collapse to the ground. However, it didn't take long for the newly attached troops to drive the civilians to build it again.

After several rounds of artillery fire, they did not kill many new soldiers, but they hit many civilians.

It did not affect the construction of the wall. The Mongols obviously did not take the casualties of civilians seriously. "Once the cannon is fired, there are ten thousand taels of gold." It is said that although the Perak Army can produce it by itself, the artillery is really a gold-eating beast, and the ammunition is also a waste.

This is a huge expense. Especially now, production capacity has been unable to be increased due to key reasons such as nitrate.

When they came up, Ouyang Xuan emphasized many times that they should pay attention to economy and use good steel on the blade. Cao Ergou thought in his mind that shelling the earth wall was really not a cost-effective business, so he ordered the shelling to stop. On the one hand, he wanted to
