Great Song Pirate

Chapter 361
Kong Qingxi fought in full swing in Wanshan, but Xu Yi didn't know the situation there. Whenever he arrived in a new place, he would inevitably need to fight and kill. Everyone understands this truth. Press the button, just say that Xu Yi hurried all the way, after returning from Danshui village to Jilong village, he was busy again immediately.

Seeing Xu Yi's safe return, the people in Jilong Village knew that Danshui Village must be stabilized now, so everyone was relieved.

Xu Yi is now determined to build a strong army. Song people lack cavalry, and their people are not as fierce as those nomads. His Fubo army is also facing the same problem. Horses are no good, but mules are still no problem. Yes, what he can do is to use good equipment to make up for these shortcomings, and to arm his Fubo army with advanced weapons. He wants to use a half-armed army to show the world a brand new war outlook. He now has thunderbolts, thunderbolts, and swarms are already advanced weapons, but he is still not satisfied. The current goal is artillery, and only artillery is the god of war in the future.

During the more than a month since he left, Ren Bin and Qin Huzi did not dare to slack off the tasks assigned to them. Qin Huzi chose the location of the artillery workshop next to the stream in the workshop area, which was according to Xu Yi's intention. It's done, they now need water power to provide some mechanical power, and it won't work without water.

With the efforts of Ren Bin, the newly built copper factory has already cast the blanks of several bronze cannons, and Qin Huzi has also produced drill bits, but their problem now is that the drill bits are too long, and they cannot control when they drill into the middle. Accuracy, after hearing that Xu Yi was back, Qin Huzi immediately found Xu Yi and asked him to think of a way.

Before Xu Yi could talk to Yingchun and the others at home, he hurriedly followed Qin Huzi to his secret artillery factory.

According to Xu Yi's arrangement, a strict blockade has been implemented here, and no one else is allowed to enter or leave this place without permission. This is a place he regards as the most top secret, and no one can let everyone know about it.

After arriving at the artillery workshop hosted by Ren Bin, Xu Yi immediately saw a few familiar guys with thick heads and tiger brains. These unfinished artillery quietly lay on several shelves, exuding this strange attraction, which made Xu Yi Yi was heartbroken when he saw it. In terms of appearance, this was already the artillery he wanted. The whole gun body was thinner at the front and thicker at the back, and the bore was gradually thickened from the muzzle to the tail as he said. The place is a little thicker, and the mouth of the gun bore is in the shape of a small bell mouth, which is convenient for loading gunpowder and shells. There are lugs, rear sights, etc. Generally speaking, Xu Yi felt that Ren Bin's craftsmanship was basically impeccable. He then lay on the cannon body to watch for himself. A lot of effort has been put into the casting of the cannon. Xu Yi feels that he has nothing to say and is very satisfied with the craftsmanship.

"The craftsmanship is good, very good! I am very satisfied! As expected, I, Xu, have nothing to say about Master Ren's craftsmanship!" Xu Yi patted the bronze cannon body in satisfaction, and nodded repeatedly.

With his words, Ren Bin heaved a long sigh of relief. These bronze cannons cost him a lot of effort, and he tried every means to make them, from the mold opening of the clay model to the copper water. Melting, and then casting, checking and polishing the mud form, he is here almost every day, just not to be underestimated by Xu Yi, now that Xu Yi is back, he also made affirmative statement on his craftsmanship, It showed that his hard work during this time was finally not in vain, so a smile appeared on his face.

"What kind of molds are these cannons made of? Tell me about your craftsmanship!" Xu Yi asked Ren Bin fondly stroking the cold sharp weapons in front of him.

"Returning to the lord, the younger one used yellow wax to make a mold first, then turned sand to make a clay model, then baked it, melted the yellow wax, poured melted copper water into it, and finally knocked out the clay model. Afterwards, it was polished to make it look like this!" Ren Bin hurried back.

Xu Yi nodded and said: "This method is good. I have nothing to say about the craftsmanship. It is very beautiful. How much red copper and tin are in the bronze you cast?"

"It's also according to my lord's instructions. I cast it according to the ratio of nine red copper and one tin, but I haven't tried it yet, so I don't know the specific situation!" Ren Bin continued to answer.

Xu Yi then lay on the muzzle and looked inward. The bores of these guns had not been drilled yet, and the casting traces inside were clearly visible, which was relatively rough, indicating that this was not yet a finished product. Now testing the guns is courting death, and the shells can’t even be loaded. Going in, it is estimated that they encountered a problem on this, but Xu Yi is not in a hurry, this matter is a piece of cake for him, as long as the cannon body is cast, the remaining problems will be solved.

"Let me give you an idea. I think you have encountered this problem too. It is possible to cast a cannon with clay molds, but have you ever found that tin and copper are not the same weight? When the clay mold cools, it is slower, and the tin will It floats on the top when it is cooling, so the quality of the gun body is not easy to guarantee. I think we can use iron molds to cast artillery in the future. After the iron mold is cast, it cools much faster than the mud mold, and the tin will no longer float on it. Yes, the quality of the cannon casted in this way is much better than that of the clay mold, and if it is broken, we can return it to the furnace for remaking, and it will not be consumed at all. The biggest advantage is that the iron mold can be used repeatedly, and we can cast it in a shorter time More artillery, what do you think of my method?" Xu Yi said to Qin Huzi and Ren Bin who had been following him.

After hearing Xu Yi's words, Ren Bin was quite surprised. He didn't expect Xu Yi to know so many things. You must know that tin floats on copper water when casting copper. This matter is not even Qin Huzi. Very clear!So he quickly said: "This is a good way. I discovered this problem when I was casting things before. It turns out that the lord is really all-rounder! Even the fact that the tin of the clay model can float on the copper water has long been known." Yes, but if you want to use iron fan, I'm afraid you still need Brother Qin's help! I can't do this cast iron!"

Qin Huzi immediately patted his chest and said: "If I say, let's stop using copper to cast such things, why not use iron to cast them? That is much cheaper than using copper! Why do you have to use iron to cast the mold, and then use copper to cast it? If I’m wrong, treat it as if I didn’t say it. I think it’s okay to cast this iron mold!”

Xu Yi smiled and explained to him: "You said it is not impossible, iron can also be used to cast cannons, but when casting iron, there are some problems that are not easy to solve. Wrought iron (wrought iron) is too soft to be cast into shape, and It is very wear-resistant, and once used a few times, the barrel will be deformed. Cast iron (pig iron) is easy to cast, but this cast iron is not elastic, and if it is not done well, it will explode. This is a matter of life and death. Our current crude steel The quality can’t be guaranteed. You haven’t mastered the ratio of the ingredients in the smelting furnace. Who knows what kind of cannon will be cast from this kind of thing. I think it’s better to cast bronze first! Appropriate!"

Xu Yi threw out a set of nouns, and Qin Huzi and Ren Bin became dizzy again. The hardness is easy to say, but what is the ductility?But they all understood that they must still use bronze to cast cannons, and this issue was not discussed.

On the shelf of the desktop caliper, a bronze gun barrel is firmly fixed, the muzzle is upward, and a drill bit is facing the muzzle. The front end of the long drill pipe is a drill specially made by Qin Huzi. Qin Huzi pointed The long-stem drill he made asked Xu Yi: "This drill is absolutely fine, and the size can meet the requirements. We tried it a few times and scrapped a few barrels. They all started to crooked when they were drilled halfway, and the barrels collapsed." It's a crooked one, according to what you said, it's a failure, the lord is the best at this, please come up with a solution for us!"

Xu Yi was not too polite. He leaned over his long-stem drill and looked at it, and immediately laughed. Qin Huzi really has a way. This drill is quite well made, but his drill is more than one meter long, and the middle of the drill After reaching the barrel, it was difficult to keep it straight with such a long hanging distance, so he immediately thought of a way.

"This is easy to do. After the drill is drilled into the barrel, a bracket as thick as the barrel is made, stuck on the drill rod, and inserted into the barrel together, so that it will not be skewed!" Xu Yi patted the barrel and said. .

"Good way! Why didn't I think of it? It's so simple, just stick it on a bracket! I'm a pig brain, hey!" After hearing what Xu Yi said, Qin Huzi wanted to pull his beard down, so He didn't think of such a simple way.

After solving the problem of drilling the gun bore, the next step is to polish it. This is very simple, and Xu Yi does not need to worry about it. As for the problem of drilling the fire door, there is nothing to say. Just drill in.

After finishing the boring work, Xu Yi wandered around here for a while, saw a few scrapped gun barrels, and said with a smile: "This one has been done well, and it will be fine to remelt it later, and cast it again." ! Failure is the mother of success. Without the support of these gun barrels, we will not be able to get good guns! You should do as I said first, and I have to prepare some other things before we can test our secret weapon. Here is I leave it to you!"

Qin Huzi and Ren Bin sent Xu Yi out of the artillery workshop. When Xu Yi returned home, he didn't take care of rest, so he asked Li Bo to call the carpenter here.

The gun barrel alone is not enough. If you want to try it out, you need a lot of auxiliary things. The gun mount is absolutely indispensable. Because it is still an experiment, Xu Yi doesn't want to make it so complicated. First, he called a carpenter and painted it for them. I drew a blueprint of a four-wheeled car, and asked them to build several such car frames as soon as possible.

The carpenter here is also an old man from Dulong Island. He knows what to ask and what not to ask. Although he didn't understand what Xu Yi's strange-shaped car is for, he immediately bowed and agreed. After coming down, he immediately took the blueprint that Xu Yi gave him, and started to make it according to his requirements.

After being busy with this matter, Xu Yi remembered to go back to Jilongzhai. He hadn't even hugged the child so far, so he hurriedly drove Li Bo home, and plunged into the backyard by himself, teasing his little Jiaojiao and Ru The dragon went to play.

Yingchun and the others were very happy to see that Xu Yi's body had fully recovered, and that he was not infected with the plague this time in Danshui Village, and they rewarded him with a large table of delicious food. Served him with vegetables, and made Xu Yi almost unable to leave the dining table, shouting that he was too full and was about to die of hunger.

Having dinner and drinking the tea that Yiqing personally made for him, Xu Yi felt that he enjoyed this feeling very much. This is the feeling of home. There are relatives by his side, full of family affection everywhere. It would be great if this could continue like this, but he I also know that I will definitely not stay at home like this every day, and there are too many things for him to do. From the day he came here, he is destined not to live in peace and enjoyment, but this time he decided to , Leave some more time to spend with your family.

The opening of the road to the Charcoal Valley this time allowed Jilongzhai to obtain a large amount of wood, which was enough for them to use for a long time. According to Xu Yi's request, the carpenter chose the strongest wood and quickly built four cars. The four-wheeled cart was handed over to Xu Yi.

The frame of the four-wheeled gun cart is very strong, and it is all made of thick wood. It is painted with tung oil, and it also exudes a fragrance of tung oil.

After the carpenters finished the cannon carriage, Ren Bin also completed the drilling of the first gun barrel, and the fire door was also drilled out by the way, and the subsequent polishing was completed soon.

Fortunately, Ren Bin's casting skills are quite good, according to Xu Yi's requirements, it is almost perfect, so that when installing the gun barrel on the gun mount, it basically takes no effort, and the world's first barrel artillery was born. up.

Looking at the guy in front of him who was only more than one meter long and more than ten centimeters thick, Xu Yi kept groping with his hands. He was very satisfied with the first time he made such a guy. The size of the Song Dynasty was designed with a two-and-a-half-inch caliber. If it is converted into a metric centimeter, it is a caliber of about 75 mm. The length of the barrel is designed according to fifteen times the caliber. A little over one meter, it doesn't look that big, but Xu Yi dare not underestimate the power of this little guy. This is the brainchild of him and many craftsmen to create the current cannon. Looking at it, Xu Yi is simply Just like looking at your own child, I like it and feel distressed.
