Great Song Pirate

Chapter 350

Xu Yi talked about it for a long time, but Ren Bin didn't figure out what the artillery he was talking about was. He was at a loss when he heard it. How powerful, sitting on the side with his mouth open and acting stupid, thinking that what Xu Yi said was like talking in sleep.

Is it possible to shoot projectiles five to ten miles away and hundreds of iron pellets?The giant arrow fired by the three-bow bed crossbow might not be able to shoot so far!This young leader of the Fubo Army must have a problem with his brain, so just blow it up!Anyway, Ren Bin didn't believe what Xu Yi said. He didn't know how many shocking killing weapons Xu Yi had created, so he thought Xu Yi was out of his mind.

Anyway, no matter what you say, I will just do what you say. As for whether it is as powerful as you said, it is not something I can control, Ren Bin sat aside and said to himself.

"Really so powerful?" The scalp was numb and scared, Qin Huzi didn't suspect that Xu Yi was bragging, but he couldn't help asking.

"Of course! When have I lied to you?" Xu Yi replied with a smile.

"After that, our ballista will be useless. With the kind of artillery you mentioned, my lord, and if it can be as powerful as the lord said, the ballista is nothing! What kind of things are installed, how can there be so many strange things, and even such a horrible thing can come up, I, Qin Huzi, can’t accept it now! I really want to see what the artillery the lord is talking about looks like , I seem to be unable to help you with this matter!" Qin Huzi shook his head and said.

"It's not exactly what you said. For the time being, we can still use this ballista. Even if the artillery I mentioned is built, it will not be as good as the ballista. For the time being, it can only fire solid projectiles." , not to mention the kerosene bombs that can’t be fired, and thunderbolts. It’s still very effective to use catapults to fire kerosene bombs at sea. Because of the high cost of artillery, it can’t completely replace catapults in a short time, and you don’t have to worry. You must be of use to it. Cannons alone are not enough. In the future, you will have to build some vehicles for the cannons to carry them. There is a lot of work for you. If the steel you refine is good, you can even use it. Your steel cannon is much more powerful than the copper cannon I'm talking about now!" Xu Yi smiled at Qin Huzi.

As soon as he heard that his assistance was needed to build the cannon this time, Qin Huzi immediately became interested, and hurriedly asked: "Then we have been talking for a long time, and we still don't know what the cannon that the lord is talking about will look like! My lord or Tell us quickly, and let Ren Bin know what he should do!"

"That's right! Since you want the little guy to cast this kind of cannon, my lord must at least tell me what this kind of cannon looks like, so I can think about what to do!" Ren Bin hurriedly asked Xu Yi for instructions.

"Of course, don't be in a hurry! Money is expensive! You go to the study and get the few pieces of paper on my desk! Just by talking, I'm afraid you don't understand. I've already drawn a few pictures. Let me tell you the picture, so you can understand it faster!" Xu Yi said.

Qian Gui is now Xu Yi's deputy commander of the personal guard, and Daniu is Xu Yi's personal attendant. The two are young and have no family members, so they have always stayed by Xu Yi's side. After hearing Xu Yi's order, Qian Gui has been feeling very itchy for a long time. What the lord just said is scary when you think about it, so you should hurry to get the picture and see what this powerful guy who hasn't been created looks like before we can talk about it!The money was so expensive that I ran into the study, and took the pictures from the table. Looking at the paintings on them, I couldn't see anything famous, so I hurriedly handed them to Xu Yi.

Xu Yi got up and spread out the pictures he had drawn on the table, and called Qin Huzi and Ren Bin over. They quickly gathered around the table and looked down.

"Isn't this just casting a pipe out of copper?" Qin Huzi shouted immediately.

Ren Bin didn't dare to yell like this with Qin Huzi, but he didn't care much, he thought it was such a difficult thing to do!It's just a copper pipe with an opening at one end!Is this the cannon that the lord talked about that day?This is too simple!

Seeing the faces of the two of them, Xu Yi knew that they underestimated the power of this thing, and seriously underestimated the difficulty of casting this kind of thing, so he was not in a hurry to explain to them, and first told them the required size (why? Neither the size of the Song Dynasty nor the modern conversion method can be found), and there are also subtle requirements such as trunnions and fire doors.

The two listened to Xu Yi's explanation with disapproval. In their eyes, there was nothing particularly difficult about this thing. It was bare without any patterns on it. It was much simpler than having inscriptions when casting bells and tripods!
"Master Ren, take note of these, but you must not ignore my request. Don't think that this thing is just a copper pipe with an opening at one end. You must not underestimate the difficulty. First of all, the hollow barrel requires The front and back must be absolutely normal in thickness, with no difference of a single centimeter, and must be absolutely round, with no irregularities, not even the slightest. Moreover, the centerline of the entire gun bore must be absolutely straight, and there must be no deviation by a single star! The gun wall at the rear is thicker, and it becomes thinner as it goes to the front. There is also a slight bell mouth at the mouth, which is convenient for loading gunpowder and shells, and enhances the strength of the muzzle. For safety, there are three to four reinforcements on the gun body. Muscles, these seem simple, but in fact it is not easy to do!" Xu Yi sneered slightly and said to the two people, thinking that if you underestimate this thing, it will be enough for you!

After hearing Xu Yi's request, the two experts immediately did not dare to underestimate this object anymore!Casting is easy, but it is not easy to meet Xu Yi's requirements. The shape is easy to say, and it can be made when making molds. The front and rear thickness must be absolutely the same, this is not easy to handle!Just now they thought that Xu Yi was playing tricks, but after careful consideration, they realized that it is simply too difficult to meet Xu Yi's requirements. These requirements are simply too much!The more the two of them thought about it, the more they felt that it was difficult to handle, and gradually they frowned. Isn't this deliberately making things difficult for others?

"Do you think I'm making things difficult for you?" Xu Yi asked the two of them with a smile after watching their faces change.

"Don't dare! My lord's request must be justified! I don't dare!" This time it was Ren Bin who spoke first.

"It's true! The appearance of this cannon is easy to talk about, but it seems that the lord's request for this cannon chamber is too much! This is not easy to handle!" Qin Huzi followed Xu Yi for a long time, knowing his temper, so he said, the implication is true It's a bit difficult.

"To be honest, I also know that this cannon is the most difficult to handle, but I definitely don't want to make things difficult for you, Master Ren. You must know that there are too many problems involved in this artillery. These requirements are related to the wealth and lives of the brothers who use this artillery. You must know If it is not round or of the same thickness, the shells will either not fit in, or they will not come out. If they can’t fit in, it’s okay to say, but if they don’t come out, Qin Huzi may imagine the result, which is bombing. Think about such a big copper guy. If it explodes, will the brothers standing next to it be killed? This is comparable to a large thunderbolt, and I am afraid that no one will survive within ten steps!" Xu Yi said.

Qin Huzi thought this was indeed the case. If such a big thing exploded, the power would definitely not be too small, and the people nearby would probably be killed or killed on the spot, so the sweat on his forehead immediately dripped down. I dare not underestimate the difficulty of making this thing.

And even though Ren Bin didn't know the power of thunder and thunder, he knew from Qin Huzi's appearance that it was definitely not a fun thing, and it might kill someone!Xu Yi said that once the chamber explodes, no one will survive within ten steps. This is a deadly thing. If the thing he made explodes on the spot, I'm afraid his head will not be able to keep it!Sweat dripped from his forehead immediately.

Xu Yi then said to them: "Even so, it is reasonable for me to demand that the centerline of the barrel must not be crooked. If there is a barrel that is not absolutely straight, if it is a little crooked, the shell will not follow the planned route. If you fly, you will lose your accuracy. If you can’t hit your opponent, it’s the same as if you didn’t fight! Think about it, is this the truth?”

Qin Huzi's sweat became more intense, and both of them nodded their heads one after another, wondering if they understood the truth.

Xu Yi didn't give them a little time to digest, and then said again: "When the gunpowder explodes, it will generate a very high temperature, and it will expand rapidly, causing a lot of pressure on the cannon. If you are not careful, when the cannon body is cast If there are cracks, hidden wounds, trachoma, or air bubbles in the middle of the gun wall, what will the result be? The result is that the gunner will be blown up, killing the gunner on the spot or being shocked! Can’t be sloppy!”

The two of them were almost fainted by Xu Yi's fright. This artillery sounds very powerful in killing the enemy, but if it is not done well, it will be like suicide for the user. This thing is too scary!

Xu Yi turned around and sat on the chair, no longer talking, just drinking tea from his teacup, not disturbing the two of them, let them digest their own requirements first.

The two of them looked down at a few simple pictures, and the more they thought about it, the more they felt that it was not simple, and the more they thought about it, the more scared they became. It is really not easy to make this thing according to Xu Yi's requirements!Both of them began to think about what method to use to cast such a dangerous thing that could meet Xu Yi's requirements, but after much deliberation, they still felt that there was no way to complete the processing of the inner chamber. Ren Bin felt that what he said just now was too much. When it was a little full, his legs began to tremble. If Xu Yi couldn't make something that satisfied Xu Yi, would the pirate leader kill his whole family?He didn't dare to think down.

Qin Huzi didn't have his ideas, but felt that the matter was tricky, so he helped Ren Bin find a way.

The more Ren Bin thought about it, the more frightened he became, and in the end he couldn't bear the psychological pressure. He knelt down to Xu Yi with a plop, and shouted: "My lord, please forgive me! I'm afraid it will be difficult for the little one to fulfill the lord's request! I hope the lord will forgive the little one, Little ones really don't have this ability!"

Xu Yi almost dropped the tea bowl on the ground. This Ren Bin is too cowardly. I just made some demands first, and wanted him to use his brain to find a solution, but unexpectedly, he frightened him like this. If he was scared out of his wits, he would not dare to do it in the future, so he quickly got up and helped Ren Bin from the ground, and comforted him: "Master Ren, don't be afraid, this kind of thing has never been done before, you It’s not surprising that I can’t remember how to answer my request for a while, I won’t blame you, everything is difficult at the beginning, even if the cannon you cast can’t meet my requirements, I won’t blame you, first of all You have to find a way to do it. Don’t be afraid of success or failure. As long as you dare to do it, you will always succeed. Don’t worry about this. Don't worry, just do a bold experiment, as long as you do things for me sincerely, even if you fail, I won't blame you!"

After hearing Xu Yi's words, Ren Bin was somewhat relieved, and Qin Huzi next to him said to him: "You just think too much, our lord is not a person who kills without blinking an eye, and I, Qin Huzi, have been with the lord for a long time Now, I know better than you how he treats us craftsmen. You don’t have to be afraid. Even if the things you make are not good, the lord will not blame you. I will guarantee you this matter with my head! I used to make a few for the lord I never made anything right away, and it took a lot of effort to meet the satisfaction of the lord, just do it, and do it again if it doesn't work! What is there to be afraid of?"

After Qin Huzi's words, Ren Bin was really relieved, so he bowed and said to Xu Yi: "Since the lord trusts me as a newcomer, then I will be bold and try to make it according to the lord's request." , if it doesn’t work, come again! I will try my best to do it well!”

Xu Yi patted him on the shoulder and said: "Your words are fine, don't think about the problem of the gun barrel, you have to find a way to solve the defect that the gun body can't have trachoma and other defects, after solving this problem, then think about it. The problem with the barrel!"

After hearing Xu Yi's request, Ren Bin hurriedly said: "My lord, you can rest assured. I have been doing copper casting for so many years, and I still have a little confidence in this aspect. The key is to master the raw materials and smelting. Molds are also very important, and there are still many points in it, so I won’t introduce them one by one to the lord, I have a certain degree of confidence in this!”

Xu Yi thought to himself that he wanted you coppersmiths to come here because he wanted your experience in this field, otherwise I would just melt some copper water and pour it out by myself?Hearing that he was certain, and seeing his prudence, he knew that he could definitely meet his requirement, so he said with a smile: "Since Master Ren said so, I believe that Master Trust will be able to do this well! Then we Tell me about the materials used for this cannon!"

Ren Bin and Qin Huzi were taken aback again, what material?Isn't it just melting the copper and pouring it out?So he asked Xu Yi: "What do you mean by the material used? Isn't it made of copper?"

"Of course it's copper, and it's still bronze. You all know that bronze is just red copper with tin added. It's very simple, but you can't underestimate bronze. You must know that red copper and tin are mixed together. The strength and toughness of the bronze obtained are different with different proportions, I don’t need to tell you this, Master Ren, you know very well that after playing with copper for more than 20 years, you still have this ability!” Xu Yi explained to them.

"That's right, my lord is indeed an expert. When the ratio of red copper and tin is different, the bronze you get will be different. This little one knows!" Ren Bin quickly nodded in agreement, not daring to treat Xu Yi as a layman anymore.

"You must know that our artillery is no different from ordinary bells and tripods. It has to withstand huge pressure from the inside, so the material should neither be too hard nor too soft. If it is too hard, it will easily crack or even explode. It’s not good if it’s soft, the barrel will be enlarged after a few times of use, and the shells will get closer and closer. The life of the artillery is too short, so pay attention to the ratio of red copper and tin in the copper material. , I can give you an idea, I think that in this ratio, red copper accounts for nine, and tin can account for one. Of course, I am just guessing. Well, this is not a conclusive conclusion, let’s think about the details in the future!” Xu Yi knows a little about the bronze used to make guns, but not all bronzes can be used to make guns, and only when he finds the best formula can he use it. Make a great gun!

Qin Huzi played with steel, so he didn't know much about the bronze, so he scratched his head and said with a smile: "It turns out that there are so many things in it like the steel you told me! I learned a lot today, and I will follow the lord. Eye-opening, haha!"

Xu Yi also laughed: "Bronze, like steel, should be called an alloy, which is a metal formed from two or more different substances. The same goes for the steel you play with every day. It's just that the ratio of iron and carbon is different. I told you that before!"

"Carbon? Why is there such a thing in steel?" This time, Ren Bin didn't understand. Charcoal is something that burns at all. How could it be mixed into steel?

"Let's not talk about this, I can't make it clear for a while, I want to ask Master Ren one thing, do you know what brass is?" Xu Yi suddenly raised this question to Ren Bin.

"Yes, there is a kind of copper, which is yellowish in color and softer than bronze. We all call it brass!"

"Then have you heard of such a thing as a baby?" Xu Yi continued to ask.

This time Ren Bin shook his head and replied: "I've never heard of this! What is zinc?"

"The appearance of zinc is a bit like tin, and it is also a kind of metal. Maybe no one can smelt this thing now, but why is there brass now? This brass is better for making guns! No matter, first Let’s talk about getting a bronze cannon!” Xu Yi seems to be answering Ren Bin, and he seems to be talking to himself, he knows that there is a kind of navy brass, which is made of three metals, copper, tin and zinc, and its performance is better than that of bronze. , more corrosion-resistant, very suitable for use in a sea environment, ductility and rigidity meet the requirements of artillery, much better than bronze, but in this era, even coppersmiths don't know such things as zinc, how can there be brass? ?He probably made a mistake. He forgot that China began to smelt zinc in large quantities. It should have been a matter of the Ming Dynasty for hundreds of years. Now the Song Dynasty has not yet started a large amount of zinc smelting. Of course, few people know about zinc, but this matter he There is still a solution. Zinc smelting is actually very simple. I learned it when I was in college. In the end, I still want to get a brass cannon. Brass cannons are more durable than bronze cannons!

"I also have a solution for the barrel. This matter depends on you, Qin Huzi, to help me. I don't care about the casting of the artillery. You just have to find a way. The barrel can be kept a little smaller. Qin Huzi, you have to find a way to produce a long drill early. , Use a long drill bit to ream the hole, so as to ensure the smoothness of the gun bore, and after the reaming, it must be polished, so that there should be no flaws at all! To get a good gun bore, this drill is very important. If the center of the drill bit is not stable, The barrel of the gun will definitely not be round, let alone be very straight, it all depends on your ability, Qin Huzi, I have taught you a lot of things before, if you can’t get a useful drill bit, I’m the only one to ask!” Xu Yi half-jokingly said to Qin Huzi.

Qin Huzi's face immediately fell when he heard it, and he shouted to Ren Bin who was beaming at the side: "It's over, it's over! I can't keep my big head! When I help you, I get myself included. I'm in trouble! So How do I get the long drill bit! And it’s so big, and the center point needs to be mastered. This thing is not easy to handle, and so is the master. Why did you leave such a difficult thing to me? I have to give old man Lei Come on, this Mr. Lei has more experience than me!"

When Xu Yi said to use a drill to expand the hole, Ren Bin laughed immediately. This idea is a genius. As long as the drill is easy to use, the gun chamber will be much easier to make. As for the bits and pieces on it, they can be solved during casting. There is no problem at all, as long as he can ensure that there are no air bubbles or hidden wounds in the barrel, no trachoma in the barrel, and no cracks inside and outside, it will be fine!This time the big trouble was thrown to Qin Huzi, and his whole family's head is completely fine now, he is so happy!He didn't listen to Qin Huzi's muttering and complaining at all.

"I have another idea to share with you today. Because the inside of the gun chamber is fried and ground, the life of the gun will be limited. In order to increase the life of the gun, the more porcelain the better, we You can also make a round steel, which is slightly thicker than the barrel, and then heat the finished barrel, and smash the round steel into it. After extrusion, the inside of the barrel will be much more porcelain. What do you think? What's your idea?" Xu Yi once again came up with a wonderful prescription like a spring.

(Here is a [-]-word chapter, two updates today, guaranteed to be no less than [-] words! Brothers, check the monthly pass in your hand! It’s rotten in this pot of pimples!)
