I stood among these equipment, looked at various shooting methods and methods, as well as various equipment to shoot flying stones, and finally got some experience. There are quite a few places where the bed crossbow actually needs to be improved, such as its winding, which generally uses a cow and horse to pull the bow arm. Why not use pulley sets or a combination of jingling teeth to perform it?

Besides, many places have various flaws. Of course, even if ordinary people see it, they don’t know how to improve it. This happens to me is my strength.

After watching these students and craftsmen use various equipment, I pulled Zhong Hua aside: "Mr. Zhong, all these things must be improved. Moreover, we need to add some powerful and more concise siege equipment. By the way, is there any news now that the miniaturization and portability of those hot air balloons are now?"

"Sir, hot air balloons can be disassembled now. As you told me, several hot air balloons of varying sizes have been made. But Sir, do you think that if you don't need those siege cars alone, can you really capture the city?" Zhong Hua was still a little worried. Although he had seen the power of gunpowder, he did not believe that gunpowder could play its role in siege.

I nodded: "Let's do this, I'll give you a task. Build a city wall in the Beigu of the Yanwu Academy within five days. It doesn't take too long, but the specifications are as follows: we need to build the medium-sized city corridor of our Tang Dynasty. Are you sure?"

Zhong Hua quickly calculated and nodded: "Yes, but the length will not exceed twenty feet."

"Enough, let the craftsmen go back first. I will first think about the areas I have considered and need improvements. After two, I will give you the patterns and supervise the construction. By the way, how far is our bed crossbow?"—

Zhong Hua couldn't answer it anymore. He looked back and asked a craftsman who was studying the crossbow and asked. He knew that the range of the crossbows today is about 400 to 600 steps. This is calculated based on the materials of various woods used to build the crossbows, as well as the toughness and elasticity of the bow-arm wood.

"That's it." I touched my chin. I remember that there seemed to be a way to increase the range. At this time, Xi Junmai was commanding a large group of cavalry students to gallop past the playground. The ponytail behind the horse's butt was cut short or tied to prevent interference with the teammates' sight.

Fang Cheng and Bonahrjin, who had been following me, were still discussing which kind of horse breed these horses belong to. My eyes fell on the butt, and my eyes became brighter and brighter. Yes, I thought of a powerful new type of equipment that could obtain powerful power to drive the crossbow arms to drive the bowstrings to shoot projectiles and arrows. "Zhong Hua, can there be horse hair, leather rope, or cow tendon in the Wuyan Institute?" I grabbed it and asked excitedly.

Zhong Hua was startled by me and nodded quickly: "Yes, all of them. What you said are not only the Wuhan Research Institute, but also the Ministry of Industry."

"Okay, let's start with improving the crossbow." I was overjoyed. It's great. The torsion spring, which is made of earth. The power drive device that can be obtained by relying on various non-metallic substances is much cheaper and more convenient than the hard walls of the crossbow that are thickened.

Hurry up to the Wuhan Institute of Technology, the craftsmen began to move out a large stack of soft skin made from nitr, as well as animal tendons and fewer horse hair from the warehouse. It doesn't matter. Now they are just trying their faces. If they succeed, it will not be too late to harvest them.

The most simple one is to use experiments to illustrate that a large amount of soft skin made from nitr is divided into thin ropes, which will be used with the tendons of those animals, as well as the long horsetails and horsehair.

I first ordered the craftsmen to create a solid local frame, and two thick logs were installed in the front, covering a large amount of linen and soft leather as buffer. Then, holes were drilled at the wings of the solid upper and lower frames. A large number of cylinders made of horsehair, soft leather ropes, and animal tendons were inserted into the two ends, and then two solid logs were inserted into this new torsion spring as crossbow arms. Under my command, a small, new structure of bed crossbow appeared, but the shape was quite different from the bed crossbow, which was a bit like the motorized pedal in later generations. The main beam was placed on the bracket, and two torsion spring groups were installed on both sides of its front end. Each spring group drove a crossbow arm, and the end of the wooden pen was connected to the bow string, and the bow string was straight.

There is a woven mesh bag that accommodates projectiles, and arrows can also be installed. The upper side of the beam is equipped with a long dovetail groove. A slider with a long guide rail can slide forward and backward along the long groove. A delicate firing mechanism is installed at the back of the slider, which can easily lock and release the bowstring. There is a winch at the end of the beam. The operator can drag the slider through a board-moving handle. When the firing mechanism locks the bowstring and pulls it backward, the weapon is in a ready state. A sight is also installed on the beam, which makes it easier for the user to aim at the target. In order to prevent the work of opening the bow from being completed in one go, and the projectile force of the weapon can be adjusted to obtain the required range, a circular ratchet is added to the winch, making the operation easier and more reliable.

However, although it is a face-testing product, as small and exquisite as possible, it is almost as tall as me. Finally, it took a day and a night to concentrate a large number of craftsmen with profound skills in the Wushu Research Institute to put forward a lot of opinions as reference. I also humbly accepted their opinions. After all, I am not a professional in making equipment, they are, and I am just slightly higher in terms of knowledge and theory than them.

It was just that the thing was finished. These craftsmen who were familiar with making various equipment were amazed by this because the appearance of this thing was already very different from the bed crossbow. As I said, it was very similar to the kind of turrets in later generations.

The next morning, Duan Yunsong, Xi Junmai and General Su were invited by me to join in the fun. After all, these things must be used by the military. Only through their evaluation can we further understand the advantages and disadvantages of this new long-range strike weapon.

Sure enough, these three people were very curious for a long time when they saw this thing, but since they had not tested it, they couldn't say anything, so they could only make an objective evaluation of it. However, the craftsmen really appreciated this torsion spring, thinking that it was really incredible to have such a powerful crossbow arm just by just a bunch of messy things.

However, Su Dingfang and Xi Junmai were not optimistic about this new weapon, and their tone was a little contemptuous, as if they were talking about the wood texture of this thing. Damn, it was obvious that they had no confidence in me. As for Duan Yunsong, they had to follow me for the longest time and understand my talents. They only listened to me attentively introducing the structure and principles of these weapons.

Duan Yunsong even wanted to try to move the crossbow arm with his hands, but the consequences naturally ended in his failure, which made him even more curious.

Zhong Hua arranged for the man to place the target at every fifty steps, the farthest was 500 steps, and the nearest was 100 steps. After everything was done, he dispersed the crowd in front of the fort and prepared to start a test firing.

The first test was a target a hundred steps away. Of course, I had no choice but to become the first tester. I pulled the bowstring to about halfway, and with a slight force, I lifted the turret with a very balanced center of gravity. The main purpose is to use a free-rotating base between the base and the crossbow body to give this turret a flexible direction and elevation angle.

A large number of craftsmen, craftsmen, officials from the Wushu Research Institute, and the military personnel I brought to visit have already set their sights on me. They have no hope of whether they can hit targets a hundred steps away. They want to see how I, a celebrity, use this new weapon.

After aiming at the target, I signaled the person next to me to put a stone ball into the net bag and pulled the plate machine. The powerful reaction force drove the crossbow arm and even drove the bowstring. Only a crisp sound was heard by the target that was a hundred steps away. Everyone's eyes were immediately attracted by the target that made a strange sound.

"Ah?!" Su Dingfang didn't know if he wanted to buy Xi Jun to compete with whom his mouth could be opened even wider. In short, the back grooves of the two of them were exposed. In front of them, the wooden archery target had been smashed into pieces by Shiwan and fell to the ground. It was indeed powerful enough, and this was half-stringed. But what I regretted was that I didn't know if I had hit the Red Heart. It felt like I was a blocker. I loved this thing so much that it was much stronger than my Six-Stone Bow. After all, I had never shot the target with the bow, and it was so good to hit it with this thing.

Someone had already taken the target. Sure enough, the place hit by the stone completely turned into wood chips. It seemed that the half-string power was far more than a hundred steps. Xi Junmai and Su Dingfang's expressions became solemn, and they began to examine this attacking turret that looked much bulkier than ordinary crossbows.
Chapter completed!
