Wang Rulong, the life-savior, made Chen Mu feel confused all the way.

When I returned to Xiangshan, I looked at the craftsmen of the Military Weapon Bureau kneeling all over the ground, and my mood that had just been relieved was even more disturbed.

"Whatever you do, get up!"

The old craftsman was shaking on the ground with the head of Guan Yuangu. It was obvious that the news of the cannon explosion in this battle had spread, making the craftsmen panic.

The gunpowder craftsman Xu Erjin and his several gunpowder apprentices stood far away to watch the fun. His medicine was fine, it was all about artillery.

"All up, go whatever you should do if you're fine, get up!" Chen Mu looked at him and his scalp was numb. He didn't want to blame anyone, but these craftsmen had the eyesight, "Jiang Guan and I go to the Military Weapons Bureau."

Chen Mu did not want to punish or punish the artillery. The artillery made a lot of contributions in combat. Although it had only fired less than forty artillery, it was very useful. If it weren't for the rate of 100% explosion after use, it would have been an excellent artillery, and it would have been used even if it was installed on the ship.

After entering the Military Weapon Bureau and someone to close the door, Chen Mu asked Guan Yuangu with a calm face and said, "Guan Jiang, what's wrong with the new cannon? It shouldn't be so explosive!"

A calm face is not because of anger, but because of real doubt.

"Don't bow, I didn't blame you, just tell me the story of casting cannons in the first place."

Chen Mu has been trying to create a cannon, but he hasn't seen the process of casting a cannon several times because he thinks that craftsmen must know more than him, but now he must understand what the problem is.

"It's all because of the old man's heart's desire to be quick. Qianhu said it was light and the shells were big, so he wanted to build a 300-pound and five-pound cannon..." Guan Yuangu complained again as soon as he opened his mouth, and was interrupted by Chen Mu. "Just telling how the cannon was made, he must have used other methods."

"The cannon maker said that 300 kilograms can only be made two kilograms. The old man refused to listen and insisted that they make five kilograms cannons. This made them come up with the idea of ​​making iron cores and cast iron skins to fool the military soldiers. If thousands of households want to blame them, blame the old man. The old man is not good at supervision!"

"Make a core of a wrought iron, and pour a pig iron into a skin?"

Chen Mu understood and waved his hand and said, "It's not your fault, I'm going far away. It's not anyone's fault now. Finding the problem to solve the problem and casting a good cannon is the right thing to do. I just want to know why using this cooked iron core, pouring pig iron skin can make three hundred kilograms of cannons shoot out five kilograms of cannons, and it can be fired for a few more rounds before it explodes."

"The iron is tough and the pig iron is hard. It might be better if the copper skin is poured outside. Someone tried to pour iron with copper core, but the copper was soft and it was melted and shrinking inward, which would not be done." Guan Yuangu felt much more relieved when he heard Chen Mu's intentions. He talked to Chen Mu incessantly: "This time the cannons were blown up. The old man felt that it might be because it was not easy to see that there was something wrong with the iron sheet after pouring it. When there was any problem, he would blow it up."

The melting point of copper is lower than that of iron, and the shrinkage rate of copper is even greater. If you use copper as a core, you will definitely break it... Chen Mu's eyes lit up, and his craftsmen went astray again.

Iron-core copper shells are not copper-core iron shells. Of course, if you consider the cost-effectiveness, this kind of cooked iron core and pig iron shell cannon is obviously good.

It's nothing more than that the barrel becomes smaller or continues to thicken.

"It's okay, there is plenty of time for Guan Jiang to build new cannons later. This time, Chen won't set the weight of the cannon for you. There are two kilograms of insurgent cannons, five kilograms of ammunition, and ten kilograms of ammunition. These three types of cannons should be done according to the thickness first. No matter what craft you use, whether it is wrapped in iron, copper sheets, iron bones, or even all copper cannons, it will be no harm."

"Someone from the Military Arts Bureau will calculate how much these types of guns are costly, and do it lighter little by little, using copper and iron. If you don't need Curry, go to Haojing to find Li Dan and Huayu, and ask them to buy them from the foreigners to create one that can be used to fight 300 guns without blowing them-how long will it take."

Chen Mu said at the beginning that Guan Yuangu called the Military Weapon Bureau to record the records. After recording the old craftsman, he was stunned. He took a deep breath and was about to agree to it, but was interrupted by Chen Mu: "Three months, can Guan Jiang figure out how much the two-pound cannon weighs?"

He really suffered the losses of craftsmen. In this era, craftsmen rarely knew to discuss with their superiors.

Chen Mu used four broken cannons to figure out one thing. Even if it was him, the craftsman would not dare to discuss it with him. No matter how long he asked for it or how heavy the cannon was, the last cannon must be so heavy at this time.

Craftsmen dare not adapt without authorization. If the superior understands these things, the requirements put forward in compliance with regulations may appear in the end. If the superior does not understand, and like Chen Mu, the lighter the cannon, the better, then the final thing will be the cannon that can barely be fired, and a battle will blow into a pile of scrap iron waiting to be restored.

"able!"

After only thinking about the regulations of one cannon in three months, Guan Yuangu still had this confidence and bowed: "Don't worry, thousands of households are safe. Within three months, the old man will definitely be able to make two-pound cannons! He can shoot three hundred cannons!"

Chen Mu nodded. This time should have left a margin in his imagination. He only needed Guan Yuangu to use different techniques to create several cannons, bronze cannons, brass cannons, cast iron cannons, and cast iron cannons, which can also fire a few cannons of 300 cannons. He will compare them at that time.

This is naturally a huge cost, but he can already bear it. Not only did Zhang Han plucked away 1,500 pieces of silk, but also the silk, woven by Xiangshan, and there was no need to touch his own private money. The money he had just cut into Xiangshan Curtain could cope with the consumption of cannon building.

Copper and iron are not expensive for Chen Junye, a thousand households in Xiangshan.

It is only 100 kilograms of iron and 2 taels of silver for a hundred kilograms of steel, and even 100 kilograms of Sugang is only 3 taels and 6 coins.

Copper is a little more expensive, with 100 kilograms of raw copper; 100 kilograms of yellow and 100 kilograms of red and 100 kilograms of red.

Only the cost of the entire copper cannon is high. If it is used to build a ship cannon, it may take a thousand pounds of cannons to reach a hundred taels, and Chen Mu can afford the other cost.

"There is another thing, Guan Jiang is waiting for me to look for it." Chen Mu flipped the notes and found it and said to Guan Yuangu: "When firing the splash bullet, the splash surface is too messy. When using a bag or a large bamboo tube to hold the battle, it is inevitable to be scattered. Make a wooden chamber holder, wrap it around it, and make a cylinder slightly thinner than the muzzle. It covers the thin cast iron sheet and seals it inside. Just use small cast iron balls to make this bullet as heavy as a large bullet. This is easy to make."

"The same three types, two kilograms, five kilograms, and ten kilograms, to prepare for future artillery."

This is not a difficult requirement, it is very easy. Guan Yuangu easily agreed and said, "Don't worry, thousands of households, this is easy to do."

Chen Mu nodded and walked out of the Military Weapon Bureau, crossed the threshold and suddenly turned around and said to Guan Yuangu: "There will be a problem if you fire a few guns on the artillery battlefield. The military Weapon Bureau cannot escape the blame. Thinking of the first offense, all the craftsmen on the artillery field will leave their salary for three months, and the manager will be fined for half a year, and supervise each other to observe the results."

"New artillery is well built, and the craftsman will pay the salary. In addition, there is a reward. If you pass it on, please inform each artillery - the rebuilt artillery, you can't get it up and explode."
