The rebels did not hesitate to stop for another day, mainly for training.

The training involves but is not limited to the continuous formation training of the Qingjin soldiers. Other soldiers may practice formations or fighting skills. The most important thing is to practice offensive and defensive tactics based on the city.

The carpenters have finished building the equipment, new siege ladders, trench bridges, and siege spines, all newly built.

There is also a door breaker.

The so-called door-breaking tool is the door-breaking tool that Li Mengxi thought up for individual soldiers. It is a short log with two lifting rings attached to it, which can be used by a single soldier to break the door.

The door breaker sent by the carpenters has a very simple structure, a locust wood stake as long as an arm, with rope rings tied at both ends, and that's it.

As an individual weapon, it naturally needs to be carried by a single soldier to be practical.

I asked a soldier to put the door-breaking tool on his back and run to try it. According to the soldier himself, although it was heavy, it was not bad.

Carrying a heavy piece of wood will increase the load, but for the soldier personally, there are no other disadvantages except the load.

Doorbreakers can even provide defense.

If you carry a piece of wood behind your back, you can prevent stray arrows no matter what.

For Liu Guanzhang, Lu Zhong and other soldiers, the door-breaking device was extremely novel, because swords, guns, swords and halberds were not uncommon, but they had never seen wooden stakes on their backs used as weapons.

What Li Mengxi said was so surprising that Zhang Fei didn't believe in the ability of the door-breaking device and insisted on giving it a try.

Everyone worked together to find a place to test.

In the city, I deliberately found a house with a door, bolted the door from the back, and then knocked it from the outside.

Zhang Fei picked up the wooden stake and banged it against it twice. Zhang Fei stopped, because Zhang Fei suddenly remembered what he said yesterday. When the siege spine hits the city gate, it is best to hit it wherever it hits.

It was discussed at that time that it was best to hit the edge of the city gate on one side.

Thinking of that moment, Zhang Fei adjusted the door breaker and banged it against the edge of the door on one side of the house. After a few blows, there was a click and the door bolt broke.

It's very useful, but Zhang Fei doesn't really approve of this thing. "If you ask me, just kick it with your feet. Can't you just kick the door open?"

This involves the subtle and subtle aspects. Based on experience and intuition, Zhang Fei feels that kicking with his feet is more effective than breaking the vertebrae of the door.

But whether it is more efficient to kick directly or to break the door vertebra, it is more accurate to verify it through experiments.

Yes, you can make a door of the same material and thickness, and then have two people of about the same size and strength, one of them kick it hard with their feet, and the other of them hit it hard with the broken door spine. After comparison, it is easy to find out which one is more efficient.

Li Mengxi did not do the experiment, but he was convinced that the door-breaking device would be more effective than pure human power.

Otherwise, in future generations, anti-riot agencies will not be equipped with door-breaking devices.

Whether it is made of wood or an iron pillar as thick and long as a grenade, it is much more efficient than kicking.

As mentioned, the door-breaking device is a hundred-man-level tactical equipment equipped to meet the needs of breaking into the city during chaos in the city. One hundred people have one door-breaking device is enough. The door-breaking device is not used at ordinary times, only used when attacking the city.

, which will not bring any logistical burden to ordinary soldiers.

Li Mengxi felt that ordinary hardwood door breakers were not the most efficient. He wanted to really get a pure iron cylindrical door breaker, but he didn't know how much a thick and short iron stake would weigh and how much a person could carry it.

Can't move.

"Twenty or thirty pounds, you can't carry it on your back." Guan Yu said.

It’s good that it’s not too heavy. Come to think of it, the door-breaking devices used by riot control agencies in later generations are also made of iron. People can’t carry them around, and there’s no chance they won’t be able to carry them on their backs.

Yesterday when I was studying the siege vertebra, I figured out that there are basically two situations in which a door can be broken. In one case, the siege vertebra breaks the door bolt and the city gate is wide open. In the second case, the siege vertebra breaks the door panel.

The door shaft is not broken, but the door is broken, so the door is also broken.

Regarding the second point, it is better to make the siege ram with a pointed head. The pointed hammer head can increase the pressure and increase the destructive power when hitting the door.

The siege vertebra is like this, and the door breaker can also be like this. The door breaker can be made into a cone-shaped tip at one end and flat at the other end, so that it has two uses.

In addition to the door breaker, I also tried the shield array today.

Piling shields into ladders is not high enough to attack a city, but in places like the city, where there are generally low buildings, shield ladders can be used appropriately.

Yesterday I tested the shield ladder and found that the shields were uneven in size and not very satisfactory.

I found a lot of large shields from the army and will try again today. I am in front of a residential house. This residence belongs to a wealthy family. The earthen walls are more than ten feet high. It is an excellent place for testing.

First, one of the sword and shield warriors stood up under the wall and raised the shield, then another person behind him, half-kneeling and raising the shield, and then two people, half-kneeling, holding up a ladder with their hands.

In terms of the height of each posture of the human body, whether half-kneeling or kneeling directly with the shield held above the head, the height is more than half a meter. This starting height is difficult to reach in one step.

It was Li Mengxi who came up with the detailed tactical moves. Two people faced each other and held hands to form a bridge. It could be raised or lowered slightly. They could also carry a shield to make a ladder.

That's just right.

One person is half-kneeling on the ground with a shield on his head. The height is too high. Adding a step to transition is just right. The first step is smooth.

In total, it took four people to build the ladder.

Then the swordsmen and shield warriors retreated and rushed forward, step by step. Following the momentum, they rushed to the top, stepped on the shields as high as a person, reached the top of the wall with their hands, and turned over in.

The shield warriors stepped on the shield bridge very quickly and jumped into the wall one after another.

Li Mengxi counted the numbers and found that on average, one person would be added in two seconds.

Although there are other ways to climb over the wall, such as a team of two people responsible for pushing people in with their shoulders, this method is too slow, and when soldiers climb over the wall, there are big gaps in the defense.

As for the ladder bridge, soldiers can still maintain their normal shield-raising posture when crossing the wall.

The shield bridge tactics were almost perfected, and Li Mengxi realized that the key problem was not the tactics, but the shield.

A larger shield is needed to build a shield bridge, and a small hooked shield will not work. At the same time, the cavalry also needs to carry a shield to strengthen the back defense. The infantry swordsman and shield warrior also have a shield. When attacking a city, all siege soldiers need a shield.

The Dancing Warrior held his shield and ran into the crowd, and fought with the people with his shield and knife. The shield seemed not to be too big.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! Whether it is building a shield array or building a shield bridge, the bigger the shield, the better.

So, between two choices, what is the most suitable size for a shield that takes both combat and shield wall into consideration? Li Mengxi has no answer to this question.

A universal shield type that can reduce costs, improve equipment versatility, and reduce logistical pressure is needed.

Just like the light and heavy machine guns, add a universal model.

What Li Mengxi could think of was to wait for him to settle down, collect various shields, and then carefully select the most suitable universal shield type. Then this kind of shield could be used by Dancing Warriors in hand-to-hand combat and siege warriors.

You can use this defensive arrow to attack a city. You can build a general-purpose shield and shield wall, and the shield bridge is large enough to build a good shield bridge.

Everyone went to the top of the city again, where a new siege ladder was set up.

This siege ladder is different in terms of its steps and width.

Each step of this siege ladder is made of two pieces of wood built together. One chopstick is easy to break, but two chopsticks are not.

What is particularly clever about this method is that in addition to improving the defense of the ladder, it also widens the scope of material utilization. Sometimes, it is difficult to find wood that is as thick as an arm, so multiple thin branches can be tied together to make the ladder.

It's hard to tell, but the thin branches are tough and soft, so they are more resistant to being hit.

In addition to the detailed modification of the steps, the width of the siege ladder has become very narrow, just wide enough to accommodate one person climbing, without any extra width.

Looking further down, there are six trench bridges built side by side on the trench outside the city, one next to the other, creating a wide passage on the trench.

Outside the city, there were soldiers holding their knives against the trench bridge and then stepping on it with their feet.

It's not possible to step on it with your feet. The soil is so hard that it's a bit difficult to press the knife into the soil with your feet.

It was still necessary to hit it with a shield. The soldier picked up the shield and smashed it twice, smashing the knife into the soil.

The Huanshou Dao has a slender blade and is as useful as an iron drill.

On the city, Li Mengxi poked his head around and couldn't see clearly. The battlements were taller than he was.

In order to have a clearer view, Li Mengxi climbed up to the battlements and stood there with his hands on the battlements. Liu Bei was afraid that Li Mengxi would accidentally fall, so he held Li Mengxi's collar with his hands.

Beside, Lu Zhong saw this scene and laughed secretly.

There are stones on the city.

"General Guan, try smashing it down." Li Mengxi glanced down at the ladder and called to Guan Yu.

Guan Yu glanced at the stone at his feet, leaned over and picked up a stone as big as a basin, carried it on his shoulders, raised his hands above his head, and threw the stone with all his strength, and it flew out.

Boom!

Stones fell to the ground, and there was a sound of wood clicking.

But when he saw the place where the stone hit, Li Mengxi was happy.

The stone thrown by Guan Yu missed the ladder and rolled onto the trench bridge.

Li Mengxi looked towards Guan Yu, and Guan Yu said quietly, "That's too much force."

When Guan Yu exerted such excessive force, Li Mengxi realized a problem. Guan Yu, Zhang Fei, and Liu Bei, these three people were far more powerful than ordinary people. They could carry stones and throw them, which ordinary soldiers could not

No, when soldiers throw stones, two or three people can only work together to move the stone to the battlement, and then let go and push it down.

That is to say, most of the time, the stone is not thrown, but pushed.

In view of this, Li Mengxi decided to conduct a test based on actual combat.

He also asked Guan Yu to just push the stone down without lifting it up.

Guan Yu did as he was told, and brought a large stone and pushed it down the ladder. The stone rolled up and hit the steps. After being carried several times, the stone finally fell down the slope, and then rolled down the slope to the trench bridge.
