Li Mengxi later returned to the Chinese army's tent and was busy at his desk. He wrote down all the "Trojan Horse War Techniques". Then, he put away the cloth and pen and went out to look at the siege equipment.

There are fifty siege ladders. They were all measured and found to be of sufficient length.

In addition to length, there is another place to test, which is the sturdiness.

The wood in the army was rarely eight feet long, so the main shafts of the siege ladders were all connected with wooden falcons.

The strength of the falcon attack should be acceptable. When Li Mengxi returned, Liu Bei, Guan Yu, Zhang Fei and others were testing the sturdiness of the siege ladder.

The test method is to simulate possible situations during a siege. The siege ladder will suffer the most collisions, probably being pushed over and then smashed to the ground.

Therefore, the test method was very simple. First, put the siege ladder up, and then suddenly push it aside.

With a bang, the siege ladder hit the ground hard. If it fell down several times, it would pass if it didn't break.

There were fifty siege ladders, and each one fell down four or five times on average. The test was completed, and none of them was broken.

Li Mengxi thought it was okay, Guan Yu also thought it was okay, and so did Liu Bei. They all thought it was normal for the siege ladder to be ready and not one of the fifty to be broken.

In fact, such a pass rate is quite remarkable.

To make one of the fifty not broken, carpenters first need to know where the siege ladder must be strong and where it must be tied tightly.

If it was just the first time to make a siege ladder, then the fifty ladders that had just fallen would have fallen apart a lot. Because the carpenters had never made a siege ladder before, they never imagined that the siege ladder would have to fall down.

It is precisely because we have made a siege ladder once. Very early on, during the siege battle of Wen'an County, carpenters made a siege ladder. Although the scale of the siege battle was not large at that time, no matter what, the carpenters completed the complete siege ladder.

Experienced the entire process of siege equipment from production to testing.

On the eve of the siege of Wen'an County, after the carpenters completed the siege ladder, they directly pushed the ladder down and smashed it to the ground during the test. Many of them were broken at that time.

Then after the carpenters failed, they understood that the siege ladder needed strength. The carpenters also began to know how to strengthen the ladder to prevent it from falling apart and the steps from falling.

Because of the previous experience and the re-building of equipment this time, the craftsmen were able to make an unbreakable ladder in one go.

Having experience and being able to make ladders that are not broken is one of them. To be able to make fifty ladders all pass the standard requires a team of good craftsmen who are average enough to make simple equipment such as siege ladders, and

, craftsmen should not be passive and slack in work, but should work seriously.

That's the key.

Apart from anything else, motivation is definitely not a problem in Carpenter's Camp, and the reward method has always been effective.

Fifty siege ladders, all tested.

Another important siege vehicle is the siege tower. Li Mengxi went to see the siege tower. There were four siege towers. The four siege towers all looked very big, like a low, long house.

Anyway, with Li Mengxi's height, he is not as tall as a siege wheel.

The first time Li Mengxi saw the siege vertebra, he immediately wondered whether the siege vertebra was a little too wide and wider than the city gate, making it impossible to get in?

When I think about it, this problem may happen, but it will not happen in the Rebel Artisan Camp.

Making siege equipment is not just the business of the craftsman camp itself. Making siege equipment requires the help of soldiers to chop wood and transport wood. Someone also needs to explore the structure of the enemy city and find out how high the city wall is and how wide the city gate is.

Then, with detailed data, the carpenter battalion can make siege equipment with the most appropriate specifications.

Building siege equipment requires the cooperation of many parties. There cannot be too many skilled craftsmen. It is a waste of manpower to let the craftsmen cut down the wood. The warriors can cut down the wood and do it for them. With the saved manpower, the carpenters can do more complex work.

It's work.

As for exploring the details of the enemy city, it is best to let the cavalry do it for them. The cavalry has strong maneuverability and can roar to the bottom of the city and then roar away again. Only the cavalry can calmly approach the city walls and gates and accurately observe the data of the walls and gates.

Precisely because the carpenter battalions have obtained more accurate data, the carpenters can boldly make the siege equipment larger without fear of making it too big to fit through the door.

As for the siege instrument as a siege vertebra, the bigger it is, the simpler it is, because if it is made larger, the strength can be easily increased and the strength can easily meet the requirements.

If it is required to be able to withstand the impact of falling rocks and have a strong ability to pass through large wheels, then it would have to be a dojo built in a snail shell, which would be extremely difficult.

From the perspective of craftsmen, other instruments may be smaller and less difficult. However, if the siege vertebra is required for defense, the larger it is, the lower the difficulty will be.

Li Mengxi circled around the four siege trucks. Each of the four siege trucks was as huge as the other, especially the wheels. The wheels of the siege trucks were much larger than the wheels of ordinary carts. The wheels of the siege trucks

It is a giant wheel with special characteristics.

Li Mengxi wanted to climb to the top of the siege ridge to have a look. He climbed along the wheel, using his hands and feet. Suddenly, he felt his body light up and his whole body was suspended in the air.

Someone lifted Li Mengxi and put him on the siege spine.

Li Mengxi looked and saw that it was Guan Yu.

Climbing up the siege vertebra, Li Mengxi saw that the top of the siege vertebra was like a tile-roofed house, with a triangular top. The ceiling was made of wooden boards. The splicing was compact but not very dense. Li Meng saw the space between the wooden boards.

Through the gap, I looked closer and looked down. It was dark under the wooden board and I couldn't see clearly.

The gaps in the wooden board are only as narrow as half a chopstick at most. Although there are gaps, they are enough to completely defend against attacks.

Complete defense against attack means that with such a narrow gap, unless you use a knife to cut it, the crossbows and other things on the city will not be able to shoot into the gap, and the crossbows will not be able to penetrate the roof.

Given the length of the shed roof, it took Li Mengxi seven long steps to walk from one end to the other, which shows how long it is.

The roof of the shed is high and steep, making walking on it unstable.

At this time, Li Mengxi thought of a piece of knowledge about top defense. The eggshell structure has a very strong load-bearing capacity.

In other words, if the top of the siege cone is made into an arc, the defense capability will be improved several times.

The curved shell roof should be a little difficult, but it is not impossible to make.

Based on Li Mengxi's current understanding of woodworking technology, to make a curved roof, heat treatment technology is enough. The originally flat wooden boards are heated by fire, softened, and then bent into the desired arc shape.

The so-called wooden straight middle rope is tanned into a wheel. The wheel is made of straight square wood and then heat-treated to complete the arc shape. The four arcs are combined into a wheel.
