However, Yang Yan met Wei Chang, who had participated in the expedition with him, in the ordnance prison. Now Wei Chang's official position is the ordnance supervisor of the Ministry of War. The duty is to supervise the production of these military equipment. Although he was born in the general's door, but he is not interested in making a knife **, and he is not proficient in poetry and articles, but he is quite talented in civil engineering, and his ability in this area is still above his father Wei Sheng, and he is like a fish in water in the ordnance prison, and he has been studying and manufacturing tools here all day long, and he has drawn a good line of things that he came up with, and taught the craftsmen to do it, and after it is done, it is still a model, although no one cares about it, but he is still happy to do it. And learn from other craftsmen, ** flow, the understanding and ability of civil engineering and engineering are higher.

However, after participating in the expedition, the two met for the first time, after all, they lived and died together and suffered together, and they were very happy after meeting. Wei Chang had already received a notice from the Privy Council, and after the two of them said a few words, they immediately led Yang Yan to the treasury to watch. I saw that there were all kinds of utensils in warehouses of different sizes, and there were thousands of them. If you want to look at it one by one, it is impossible to look down without ten days and half a month.

Only then did Yang Yan know that he wanted to find something suitable for himself among the thousands of models, although it was not a needle in a haystack, but it was not much closer. was worried, Wei Chang said: "My lord, I have prepared a few things that I think can be used, and I will go and see these things first if my lord does not visit." ”

Yang Yan nodded, he still believed in Wei Chang's technical ability. "Okay, let's go check it out first." ”

Wei Chang immediately led him to the outside training ground, which was a wilderness hundreds of paces wide. At this time, I saw a middle-aged man with a dark and thin figure leading four people to carry a large wooden barrel more than one person high.

Yang Yan said: "What is this, it's like a big wooden barrel." ”

Wei Chang said: "This is actually the 'fire dragon out of the water' we have seen on the warship. However, the 'fire dragon out of the water' is one one, but this bucket is filled with a hundred, and the ** can reach three or four hundred steps. ”

Yang Yan nodded and said, "This thing sounds good, try it out, if it's good, I'll ask Han Shumi to make it in large quantities right away." ”

Wei Chang nodded, and gestured to the middle-aged man, who immediately ordered someone to put the barrel away, and then placed the target two hundred steps away, and then pulled a lead from the barrel and lit it with a torch.

After hearing the sound of "boom", after the smoke cleared, Yang Yan looked at the target that people had taken from two hundred steps away, and saw that the elm planks that were three or four inches thick were not penetrated by javelins, but were chiseled to pieces. Yang Yan stuck out his tongue and said, "Sure enough, I see that within two hundred steps, even the thick armor of Tiefutu can't stop it." If it is used to defend the city, it will be even more dangerous to deal with the enemy army in dense formation. Brother Wei, you really have two hits. ”

Wei Chang smiled slightly, pointing at the middle-aged man: "I don't dare to be greedy for merit, I am not very proficient in firearms, this 'fire dragon out of the bucket' was created by this Sun master, he is very researched on firearms, and the power of the firearms made by his improved **** formula is much greater than before." ”

Only then did Director Sun salute Yang Yan and said, "Your Excellency Sun Wei, see Lord Yang Commander." ”

Yang Yan said: "Master Sun doesn't have to be polite, how many such 'fire dragon out of water' buckets are there now?" ”

Sun Wei said: "There are four of the hundred, but the adults saw it just now and used one." Two hundred and two of three hundred. ”

Yang Yan nodded, and said, "Then how long will it take to make such a 'Fire Dragon Water Out' bucket." ”

Sun Wei said: "If it is five people to **, it will take three days for a hundred pieces, and four to five days for two hundred and three hundred pieces, but if it is made in large quantities, it can be done under the division of labor, and the **** can be matched at one time, and the time should be shortened a lot." ”

Yang Yan said: "This 'Fire Dragon Out of Water' bucket is very useful, I will make a suggestion to Han Shumi and make a large number of it." ”

At this time, Wei Chang said again: "My lord, let's take a look at this again." As he spoke, he waved his hand, and eight people came over carrying an object, just covered it with an oilcloth, I don't know what it was?

After lifting the tarpaulin, Yang Yan saw that it was a bed**. However, the bed crossbow I had seen before was more than twice as small, only as tall as a king's ruler and as long as a zhang. I couldn't help but say, "Isn't this a bed crossbow?" But if it's going to be smaller, is there anything special about it? ”

Wei Chang smiled slightly and said, "My lord, you try it and see if you can pull it away." ”

Yang Yan was stunned for a moment and said with a smile: "How can I pull it away alone?" However, although he said so, he still grabbed any of the twisted wooden handles, immersed himself in luck, and pulled hard, only listening to the sound of "squeak, squeak", and actually pulled the bed crossbow two feet, Yang Yan was taken aback, and continued to pull the twisted wood handle hard, only to listen to the "squeak, squeak" himself A small bed crossbow was all opened.

Yang Yanke was surprised, you must know that although the lethality of the bed crossbow is huge, it is huge and not easy to move, and it is too laborious to pull it away. Ju said that in the early years of the Great Song Dynasty, it took 70 people to open the bed crossbow for all of them. Later, after improvement, it was reduced to a single bed crossbow that could be used by only seventeen or eighteen people. Despite this, it is not convenient, and it is only useful when defending the city, or on a large warship such as Shenzhou, but it cannot be used in the field.

But this bed crossbow could be completely opened with Yang Yan's strength alone. Although Yang Yan's strength is greater than that of ordinary soldiers, if he is an ordinary soldier, he can only use two or three people.

Yang Yan couldn't help but admire: "Brother Wei, how did you get it." It's so easy to pull away. ”

Wei Chang came to the side of the crossbow and pulled a side plate from the main frame. Yang Yan saw that it was empty, and there were gears of different sizes installed with steel cables, and all the gears could be rotated together with a twist of the twisted wooden handle. I couldn't help asking, "Brother Wei, what are these gears?" ”

Wei Chang was a little proud, and said: "This is called ratchet, which was made by Shen Su in the metric system back then, and it is recorded in his [Mengxi Writings]. Using a ratchet can be very effortless. But it took me three months to assemble them on the bed**, initially with ropes, but after a few times the ropes broke easily, and then I switched to steel cables to design such a bed crossbow. And I also designed the lifting pole and bracket so that it can be lifted by just eight people. If you divide a team of ten people, divided into a group of four people to take turns to pull away, and the other two people are responsible for loading crossbow arrows, as long as they are trained, the speed is not much slower than the Divine Arm Bow. However, the ** journey is much closer, and the effective ** journey is only about 300 steps, and for iron armor like Tiefutu, it is only effective at about 200 steps. ”

Yang Yan couldn't help but exclaim again, although this bed crossbow is closer, it is very rare to have three hundred steps. It's more than twice as tall as the Divine Arm Bow. And the shape is smaller, it is easier to move, just now I saw with my own eyes that only eight people can be lifted out, in this way, although the power is much smaller, but the practicality has also been greatly improved. If properly moved, such a small bed crossbow can also be used to a huge effect in the field.

Wei Chang said: "And the ordinary big bed crossbow can also be equipped with a ratchet, so it is estimated that it can be reduced to ten to twelve people can use the bed crossbow, and the efficiency will be greatly improved." ”

When Yang Yan heard this, his heart moved, and he said, "Brother Wei, can you also make some ** thunderbolts and thunderbolts like this?" "He had used firearms on the battlefield before, and after the Battle of Fukuyama Island, he had a deeper understanding of the power of firearms, although firearms cannot completely determine the victory or defeat of the battlefield, but as long as they are used properly, they can also become a great weapon on the battlefield. Since it is necessary to fight against the Jin State in the future, if you want to restrain the cavalry of the Jin Country, you must think of more ways.

Wei Chang listened, thought for a while, and said, "This should also be okay." ”

Yang Yan said again: "By the way, Brother Wei, if the bed crossbow can be pulled with a ratchet, then the Divine Arm Bow and the Horse Emperor Crossbow that are used now can also be changed to be pulled by a ratchet?" If it can also be improved, then the power of the Divine Arm Bow can also be greatly increased. ”

Wei Chang was stunned for a moment and said, "I haven't thought about this yet." He thought for a moment and said, "But it seems that there should be no big difficulty, just use a smaller ratchet and a thinner steel cable." The adults reminded me that I would try again when I had time. ”

After coming out of the ordnance superintendent, Yang Yan didn't wait to go back, so he immediately came to see Han Yanzhi and told Han Yanzhi about the power of the two weapons he had just seen in the ordnance superintendent. It also explained that these two weapons were needed to quell the Quang Nam rebellion. Han Yanzhi is also a person who is familiar with military affairs, and after listening to Yang Yan's introduction, he immediately realized the role of these two weapons on the battlefield. It was immediately forwarded to Yu Yunwen, and with the approval of the Zhongshu, the Ministry of Household allocated money and ordered the Ordnance Superintendent to produce a large number of products.

And as time passed, people from all walks of life finally arrived in Lin'an.
