I stood in front of these instruments, looked at the various shooting methods and methods, as well as the various throwing stones of the equipment, and finally had some experience, the bed crossbow actually needs to be improved quite a lot, such as its winding, generally using cattle and horses to pull the bow arm, why not use a pulley group or use a combination of wattle teeth to carry out?

In addition, there are various defects in many places, and of course, even if the average person sees it, they don't know how to improve it, which happens to be my strength.

After watching these students and craftsmen use various instruments, I pulled Zhong Hua aside: "Lord Zhong, these things must all be improved. Moreover, we also need to add some powerful, more concise siege equipment, by the way, those hot air balloons are now miniaturized and portable? ”

"My lord, the hot air balloons can be disassembled now, and several hot air balloons of different sizes have been made according to your orders, but my lord, do you think that with these alone, you don't need those siege vehicles, you can really capture the fortified city?" Zhong Hua was still a little worried, although he had seen the power of gunpowder, but he did not believe that gunpowder could play its role in siege warfare.

I nodded: "That's it, I'll give you a task, build a city wall in the north valley of the Yanwu Academy within five days, it doesn't need to be too long, but the specifications are good, it should be built according to the medium-sized city outline of our Datang, can you be sure?" ”

Zhong Hua quickly thought about it and nodded: "Yes, but the length will not exceed twenty zhang." ”

"That's enough, let the craftsmen go back first, and the official will first think about the areas that I have considered that need to be improved, and then give you the drawings after two hours, and then supervise the construction, by the way, how far is our bed crossbow away?"

----------------------------------------------------------- Zhong Hua couldn't answer, he looked back and summoned a craftsman who was studying in front of the bed crossbow to inquire, and knew that the range of the current bed crossbow was about 400 to 600 steps, which should be calculated according to the material of the various woods used to build the bed crossbow, as well as the tenacity and bullet surnames of the bow arm wood.

"That's right." I touched my chin, I remembered as if there was a way to increase the range, and at this time, Xi Junmai was directing a large group of cavalry cadets to gallop past the edge of the field, and the tail of the horse's back was cut short or tied to prevent it from disturbing the view of his teammates.

Fang Cheng and Bo Nerjin, who had been following me, were still there discussing what kind of horse these horses belonged to, and my eyes fell on the horse's buttocks, and my eyes were getting brighter and brighter, yes, I thought of a powerful new device that could obtain a powerful power to drive the crossbow arm to drive the bowstring to throw projectiles and arrows.

"Zhong Hua, can there be horsehair, leather rope, or cow tendon or something in the Martial Arts Research Institute?" I grabbed Zhong Hua and asked excitedly.

Zhong Hua was taken aback by me, and hurriedly nodded: "Yes, all of them, my lord, what you said, not only in the Martial Arts Research Institute, but also in the Ministry of Industry." ”

"Okay, let's start with the improved bed crossbow." I rejoiced, great, that the torsion spring, which is made of earth and can be obtained by various non-metallic substances, is far cheaper and more convenient than the crossbow arm that strengthens and thickens the bed.

Hurried to the Martial Arts Research Institute, the craftsmen began to move a large stack of nitrate soft leather from the warehouse, as well as animal tendons, less horsehair, it doesn't matter, it's just an experiment at the moment, if it is fruitful, it is not too late to harvest it when the time comes.

The simplest way to show is that the large amount of soft skin made of nitrate is divided into strings, and it will be useful for those animal tendons, as well as the long horsetail and horsehair.

I first ordered the craftsmen to build a sturdy square frame, with two stout logs in front of it, and a large amount of linen and soft leather wrapped around it as a cushion, and then, drilling holes in each of the two wings of the sturdy upper and lower frames, inserting a large number of cylinders made of horsehair, soft leather rope, and animal tendons, fixing the ends to the ends, and then stuffing two strong logs into this new torsion spring as crossbow arms. Under my command, a small, new-structure bed crossbow appeared, but the shape was quite different from the bed crossbow, but it was a bit like the motorized treadmill of later generations, the main beam was placed on the bracket, and the front end was flanked by two torsion spring groups, each of which drove a crossbow arm, and the end of the crossbow arm was connected to a bowstring, and in the center of the bowstring was a woven mesh bag containing projectiles, and arrows could also be installed. There is a long dovetail groove on the upper side of the beam, a slider with a long guide rail can slide back and forth along the long groove, the rear of the slider is equipped with a set of ingenious firing mechanism, which can easily lock and release the bowstring, there is a winch at the end of the beam, the author can move by pulling the handle, and the slider can be dragged by the rope to move, when the firing mechanism locks the bowstring and pulls it back, the weapon is in a state of readiness. In addition, a sight is installed on the beam to make it easier for the user to aim at the target. In order to make the work of the bow not have to be done in one go, and to adjust the projectile power of the weapon, so as to obtain the required range, a circular ratchet was added at the winch to make the operation more simple and reliable, however, although it is an experimental product, as small and delicate as possible, but the size is almost as tall as me, and finally it took a day and a night of effort, and with the cooperation of a large number of skilled craftsmen of the Martial Arts Research Institute, a large number of opinions were put forward as a reference, and I also humbly accepted their opinions, after all, I am not a professional in making equipment, They are, and I'm just a little bit more knowledgeable and theoretical.

The craftsmen who were familiar with making all kinds of instruments were amazed at it, because it was very different in appearance from the bed crossbow, and as I said, it was very similar to the fort of later generations.

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

Sure enough, when the three of them saw this thing, they were very curious for a long time, but because they hadn't tested it yet, everyone couldn't say anything, so they could only make an objective evaluation of this thing, but those craftsmen appreciated this torsion spring very much. It's unbelievable to think that such a powerful crossbow arm can be made with just a bunch of messes.

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 of this thing. As for Duan Yunsong, who is slightly better, he must follow me for the longest time, and he knows more about my talent, so he just listens intently to me introduce the structure and principle of these weapons.

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

Zhong Hua arranged for the men to place the arrow target every fifty steps, the farthest was five hundred steps, the nearest was a hundred steps, and after everything was done, he dispersed the crowd in front of this fort and prepared to start the test firing.

The first test was a target a hundred paces away, of course, I was obliged to be the first shooter, first pulled the bowstring to about half of the position, and with a slight force, lifted this very balanced center of gravity of the battery, mainly between the base and the crossbow body using a freely rotating base, in order to give this kind of battery a flexible direction and elevation angle.

A large number of craftsmen and craftsmen, as well as officials of the Martial Arts Research Institute, as well as the military personnel I brought to visit, had already set their eyes on me, and they had no hope that they would be able to shoot at a target a hundred paces away, and they wanted to see how I, a celebrity, used this new weapon.

After aiming at the target, I motioned to the person next to me to put a stone pellet into the net bag, pulled the plate machine, and the strong reaction force drove the crossbow arm, and even more drove the bowstring, only to hear a crisp sound from the arrow target a hundred steps away, and everyone's eyes were immediately attracted by the arrow target that made a strange sound.

----------------------------------------------------------- "Huh?!" Su Dingfang didn't know if he wanted to compare with Xi Junmai whose mouth could be opened wider at this time, in short, the back molars of the two were all exposed, and in front, the wooden arrow target had been torn apart by the stone pill and fell to the ground. It's strong enough.,That's the half-string.,But I regret I don't know if I hit the heart.,It's a kind of feeling like a blocker.,Love this thing.,It's much stronger than my six-stone bow.,After all,I've never shot a target with a bow.,It's so cool to hit with this thing.。

Someone had already gone to take the target to the ground, and sure enough, the place where it was hit by the stone was completely reduced to sawdust, and it seemed that the power of the half-string was far more than a hundred paces. Xi Junmai and Su Dingfang's expressions became solemn, and they began to look at this multi-directional and multi-elevation attack battery that was much more cumbersome than ordinary crossbows.

"Go on! This time, the officer aimed at the target of one hundred and fifty paces! I shouted excitedly, got the strings up again, and smugly hummed the tune that we're all sharpshooters, each bullet destroys an enemy, aims, fires, and winds again...... There were nine targets between 100 and 500 steps, and I fired them a total of 12 times, and except for five misses, the remaining seven hit the target, and the remaining 450 targets were only knocked down and did not cause damage, and the 500 paces target did not move at all, that is, the maximum range of this thing was as high as 400 steps, and the only one I used was a cobblestone pill, and if I used arrows, I believe its accuracy could be even better.
