Although the shield formation only changed from squatting to standing, the change in movement will also bring new troubles.

What Li Mengxi cares about is these troubles in the process of exploring new tactics.

In the shield formation movement, there is also a standing shield formation, and the sword and shield warriors have also mastered it.

When the siege team charged to the bottom of the city, the shields in the hands of the soldiers were tilted upwards, thus covering their heads and half of their bodies. If the arrows shot from the top of the city fell, they would be blocked.

After being told to raise the shield to the head, the swordsmen and shield warriors stood next to each other, still holding the sword in one hand and the shield in the other. The shield was raised above the head and the sword was in the hand.

Should this be said that today's soldiers are well-trained and the results of training are shown involuntarily, or that their thinking is not flexible enough.

When guarding against arrows, the kinetic energy of the arrows is only so great that even holding the shield with one hand is enough for defense.

But in the case of a shield bridge, people will step on the shield and run, and if they still hold the shield with one hand, they will not be able to support the mass of the human body.

After a period of time, the swordsmen and shield warriors, under the coordination of the centurions and chiefs, built the shield bridge.

The swordsmen and shield warriors did what Li Mengxi said, standing as close together as possible, pressing their shields from one end of the trench to the other, and spreading them as densely as mats.

Li Mengxi took a look and saw the problem again.

The problem lies in the shields. Currently, the military's armaments are completely inconsistent. The shields are of different sizes and shapes. Therefore, the shield bridge cannot fit together perfectly. Instead, there is a hole here and a hole there.

Furthermore, according to the inherent thinking of the sword and shield warriors, one hand holds the sword and one hand holds the shield, instead of holding the shield above the head with both hands. In this way, the strength is definitely not enough.

Seeing that it was almost done, Li Mengxi asked people to get down into the ditch and climb up the ladder.

Several Liu Bei's soldiers immediately followed the instructions. The leader took a few steps back, rushed forward, jumped over the ditch, and landed on the shield bridge with a thud. The first person stepped down, and the bottom

He could no longer hold up the shield with one hand. The shield tilted and the person's feet stumbled, causing him to step on the air.

The first person to rush forward suddenly rode on the head of the person holding the shield below, and the whole audience burst into laughter.

Li Mengxi also laughed secretly.

The few people behind saw that they shouldn't rush too hard, so they carefully jumped into the ditch slowly, then stepped on the shield with one foot like stepping on a stake, then took a long step and stepped on the other shield immediately.

During this process, it was still because the swordsmen and shield warriors held the shield with one hand, which was not strong enough to support the force of an adult stepping on it, the shield collapsed in the east and west, and the people crossing the shield bridge on it also staggered and staggered.

Of the five people who crossed the shield bridge, three fell forward and backward. One was on the edge. He was about to fall and jumped down with a thud. Only one person stumbled across the ditch several feet wide and rushed to the opposite slope.

Then climbed to the ladder.

This chapter is not over yet, please click on the next page to continue reading! Li Mengxi raised his head and looked at Guan Yu and said, "The shield must be raised with both hands, one hand cannot hold it."

Guan Yu thought so.

Behind him, Guan Yu jumped down into the ditch himself. He ordered the shield formation to disperse, and then told everyone again to raise their shields with both hands.

There was another small episode in this process.

Speaking of holding up a shield with both hands, a soldier asked, "Where do you put the sword?"

Guan Yu didn't even think about it, "Put the knife on the ground."

Isn't that how it should be? The knife should be placed on the ground or held in the hand. A single knife with a ring head is not heavy.

Next to him, Li Mengxi frowned.

Although the Huanshou knife is not heavy, it is still heavy. An extra two kilograms of knife in your hand will consume a lot of energy.

As for putting the sword on the ground, if the swordsman and shield warrior were suddenly ordered to charge forward, someone would have to lower his head to pick up the sword, which would immediately disrupt the team.

It is most suitable for the sword shield warrior who supports the shield bridge to have his sword inserted into the scabbard on his waist.

But thinking of this, Li Mengxi suddenly realized that there was no scabbard! Most of the soldiers in the rebel army now only had a single sword with a ring-shou sword in their hands. There was no sheath, so there was no way to insert the sword into the sheath.

This scabbard is very important to consider because it can greatly facilitate the carrying of the knife.

It is easy to carry, just like in normal times, the knife has a place to insert it, so that when eating and resting, the knife will not be stuck on the ground and cause rust; and like now, you have to hold up the shield with both hands, the knife can be sheathed, and when it is time to draw the knife, it can be easily

Just pull it out, very convenient.

It seems that if conditions permit, the scabbard should still be made.

After Guan Yu explained the essentials again, he ordered all the sword and shield warriors to raise their shields with both hands.

The sword and shield warriors took the order and uniformly changed the method of raising their shields.

Then, Liu Bei's soldiers crossed the ditch again.

This time, the man with the sword and shield held his shield firmly, and the man crossing the ditch stepped on the shield as if he were stepping on flat ground.

Because of the shield bridge as high as a person, the deep ditch turned into a shallow ditch. The swordsman jumped down from one end of the ditch, ran a few steps, ran to the other side of the ditch in an instant, and then took a big step forward.

, rushed a little, and arrived at the ladder.

Obviously, the shield bridge works.

If we had attacked the city yesterday and had this shield bridge, the city wall might have been taken down long ago and there would not have been such heavy casualties.

Thinking further, no matter how deep the trench is, a shield bridge as high as one person is useless. You can stack another one one person high.

To build a city with a shield bridge, there is another layer of people standing on the shield bridge, and another layer of shield bridge is built. The combined height of two adults is more than three and a half meters, which can directly fill a three-meter-deep ditch.

As for whether the person below can bear the load and someone is standing on his shoulders, it is completely possible for a short period of time. One foot can step on one person's shoulder, two feet can step on two people. It is even possible. Four people can lift a shield and stand on the shield.

One foot and one person's weight are shared by eight people. This small amount of weight can be supported for an hour or two.

Taking this siege as an example, from the beginning of the battle to the final defeat of the city, it ended in less than an hour and a half.

In other words, as long as the shield bridge and human ladder were put up for an hour or two, the city might be destroyed.

There is a second method to crack the deep trenches of the city. The first method is to fill the trenches with soil. The second method is the shield bridge and ladder method. After practice, it is also very practical.

After the preliminary test was completed, Li Mengxi was still thinking about the Romans' shield bridge tactic, so he simply gave it a try.

Calling dozens of sword and shield warriors, Li Mengxi personally arranged the tactics.

First of all, the city wall is not good at all, and I don’t know who designed Nanhe City. The base of the city is so disgusting that there is no place to stay.

It was not convenient to use the city wall to practice, so we simply went to the city.

On the back of the city wall, in the corridor, and close to the city wall, Li Mengxi racked his brains and thought carefully about all the memories related to riding ladders. Among these memories, there were performances by acrobatic troupes, performances by martial arts schools, and external performances by certain troops.

, all these memories.

With these half-understood memories, Li Mengxi thought while pulling people to their positions.

First, against the city wall, there are four people on the left, two in front and two behind. These four people each hold a shield in their hands to protect their heads. At the same time, the person on the left has his right shoulder, the person on the right has his left shoulder, and the second row

, the person second from the left should take the right shoulder, and the person second from the right should take the left shoulder.

These four people, standing at four corners, share their shoulders, support the four corners of a large shield, and hold the shield on their shoulders.

Then, the same arrangement, with the same four people next to each other on the right, and another shield.

In this way, two stepping points with a height of one person were set up.

Originally, Li Mengxi thought that a person would step on one stepping point with his legs apart, but after actual operation, he found that it didn't work.

Because the span with eight people arranged in fours and fours was too wide apart, people had to do the splits.

There was only one stepping spot, and only one person stood there.

Li Mengxi ordered the sword and shield warrior to stand up. After the sword and shield warrior stood up, Li Mengxi discovered another problem.

In the square inch of the shield, when a person stands on it, his feet are almost like standing at attention. He has to stand with his feet together. As we all know, standing like this is not stable. The stable way to stand is to stand with your feet apart and stand in a triangle shape. The triangle has stability.

, so that you can stand firmly.

I can't think of a solution to this problem at the moment, so I can only put it aside for now and solve it later.

In the first row, after the people were lined up, there were a total of eight people on the bottom floor. There were two stepping points, and two people were standing.

Then, continue to line up people down.

On the lowest level, after eight people, followed by eight more people, in the second group, there are two more stepping points, and two more people can step on the second level.

Then, a third group, and a fourth group.

In total, there are thirty-two sword and shield warriors on the first floor, and eight sword and shield warriors on the second floor.

At this time, Li Mengxi ordered the eight people on the second floor and the two on the front to stand with shields on their heads with their hands on their heads.

The two people in the middle bent down and put their shields on their heads. The two people in the back squatted half-crouched and put their shields on their heads.

In this way, three steps with widely different heights appeared.

Li Mengxi frowned and thought for a long time. This is not right. This is a step, not a Roman shield bridge. The Roman shield bridge is like a slope.

After thinking about it again, I understood.

There is still a lack of smooth transition between high and low.

Then the next person was asked to stand between the high shield and the medium-high shield, and then the standing posture was between standing straight and bending down, with the shield above the head, the shield tilted, and the shield connected to the high shield and the medium-high shield behind it.

It turned out to be just right, connecting the two heights, and it was too gentle, making it a gentle slope.

This chapter is not over yet, please click on the next page to continue reading! Li Mengxi took a look and realized that this was right.

According to this method, put people into the gap again, and between the people who are bending over and holding up the shield, and the people who are squatting and holding up the shield, insert a person who is kneeling and holding up the shield. The shield in this person's hand also takes over the front and back, and so on.

A gentle slope.
