After seeing the production situation of the two places, Zhao Bing turned to a spacious open space behind where several craftsmen were busy surrounding a bifurcation. Of course, this was not an innovation, but an improvement.?????                                                                                                                                                                                                                                     

Therefore, Zhao Bing chose to install different types of crossbows according to the different gun positions, and the ammunition fired was also different. There were iron bullets and gun arrows used for "armor piercing", as well as arrows used to kill enemy sails. There were chain bullets used to destroy ship sails, anchor hooks for hooking enemy ships, and "shotballs" that killed relatively concentrated enemy groups. He had only heard of these things and had never seen real objects, so he needed to conduct trial production and a large number of experiments to find ammunition that could wield the maximum power of the crossbows.

But what Zhao Bing is most concerned about is a "company" crossbow. Of course, this is not the automatic shooting of guns and cannons in the modern sense, but the continuous shooting is achieved by installing simple mechanical devices. In fact, this is not Zhao Bing's Ming, but it is a unique weapon designed by craftsmen from the Song Dynasty, which is more than a thousand years from the time of the Song Dynasty. The principle is to store spare arrow stones in the V-shaped "mass clips", and then through the back and forth movement of a group of pentagonal gears and chain mechanisms, the waiting, loading and strike automation of the crossbow cannon.

Zhao Bing did not have much effort to realize the function of the company. Let's put it this way, if the crossbow is an ancient legend, then the crossbow will be like smoke and clouds. Because it appeared for a very short time, no physical objects were unearthed, no historical records, but was only passed down from generation to generation by craftsmen. Just like the "wooden ox and flowing horse" created by Zhuge Liang, no one can know its true appearance. What is amazing is that this kind of automatic fire crossbow is not used for actual combat, but it disappeared in a flash. It is said that it is the same reason why other automatic weapons were abandoned as soon as they were released - wasting ammunition.

As a modern man, Zhao Bing certainly would not make such a low-level mistake. He hoped that the faster the shooting, the better, so that he could hit ten. Especially when facing the charge of enemy cavalry, if he weaves an arrow net with a powerful crossbow, what kind of situation would it be? To achieve this goal, of course, it is necessary to create it first, but with just one prompt, it is so easy to make it. Now it is not the later generations with advanced processing technology and materials that are sufficient to ensure strength.

Simply put, it just drives the gear chain and makes Zhao Bing stump. If it is modern, you only need to find a rubber belt with wire to solve it, so that the required strength and service life can be easily achieved. If it is not possible, you can also use a full metal structure as a backup solution. But now it is a long time to build a metal chain. Due to smelting technology, iron processing is not easy, copper strength is not good, and it is large, not easy to move and transport. Of course, there are cost problems. After many tests, the combination of hardwood gear and cowhide chain is still used. Although the service life is short, the materials are easy to obtain, light weight, easy to process and repair, but the most cost-effective.

Several key problems have been solved now. Using a ten-pack casing, Zhao Bing estimated that the firing can reach six per minute. However, there is still a problem of poor supply of bullets and easy to get stuck in bullets. Therefore, it needs to be adjusted and modified in order to achieve the best state, and then consider whether the shooting can be further improved. After he had some guidance on the spot, he turned to another research team. The things here are complicated, but they don’t look like weapons at a high level, and of course they are not. In fact, a machine driven by water conservancy...

Zhao Bing knew that the late Song Dynasty and early Yuan Dynasty were the period when hot weapons were rapidly developed. The original firearms had already appeared and began to be used on the battlefield. He also planned to display firearms, and now he had already fired a "rocket". Of course, due to the current conditions, it was impossible to develop artillery and muskets, such as the changing era of big killers, so he could only use small steps to quickly walk to create some simple structures and easy production. He had great power to survive this level first. But even so, a lot of gunpowder is needed. But the gunpowder of this period...ah, it's really hard to say.

Chinese gunpowder originated from the accidental appearance of alchemy Taoist priests, and the manufacturing process was full of metaphysical colors. The ancient Chinese could not understand why saltpeter, sulfur, and charcoal were placed together and violently burning and explosions would occur. The ancient Chinese could not understand it well. They thought that sulfur was pure yang and savored by the two emotions, and the sound became changeable. This is a magical object. Listen to the combination of yin and yang, and the transformation of the universe was profound and profound, and did you feel that ancient wisdom was coming to your face.

The ancient Chinese military Ming families added more impurities to it: Chuanwu, Caowu, Nanxing, Pinellia, Wolf Venom, Snake Burial, Rotten Bone Grass, Heartbreak Grass, Ginger Juice, Toad Oil... These ingredients are mainly flammable substances, which shows that the Song people have not fully realized the explosive performance of gunpowder and are not mature in terms of ingredients distribution ratio. People who don’t know think they are making medicines. The effect of the attack is like burning the other party’s Chinese medicine shop. The thick smoke is rolling with poisonous gas. In addition to burning the enemy, they also hope to choke them to death.

Zhao Bing has modified the gunpowder formula produced by the Chinese medicine shop in Jiazi Town to increase the explosive power, but he also found that the gunpowder production process is too primitive. At this time, the three raw materials must be selected and refined, and then crushed into powder. The specific operation method is to weigh the portions according to the proportion and then put them in a stone mortar or wooden trough for repeated stirring to become fine powder. The second is to mix the three ingredients, which is to "pound" after mixing them in proportion. In fact, it is indeed pounded out. The size of the gunpowder particles depends on the feel of the worker.

It sounds very freehand, but it also shows that this is still in the initial stage of manual production. It is important to know that the power of firearms is determined by gunpowder first, and the quality of gunpowder is not only the formula, but also the manufacturing process. The current production method cannot guarantee quality, nor the quantity supply, which also affects the production and promotion of firearms. Therefore, it is necessary to improve the production process and production equipment first so that it can reach factory production, meet the needs of combat and the development of subsequent work.
