The transformation of the armed barge went very smoothly, and in ten days, two iron-hulled powered ships and ten armed barges were floating in the river of the shipyard, and Yang Fuliang and the students of the Ship Master School had begun to familiarize themselves with their warships.

The armed barge is not without weakness, and this weakness is extremely deadly, the ammunition compartment is the biggest weakness of the armed barge, once it explodes, not to mention the barge, the entire fleet will have to be finished.

Fully loaded with three or five tons of fire. Medicine, dozens of tons of shells, armed barges are just a floating fire . The medicine barrel, even if the ammunition compartment is attached with extremely thick iron armor, it is difficult to hide this shortcoming.

The barge artillery team is not moving, that is, it is reinforcing the ammunition compartment and dividing the ironclad compartments, Yang Meng does not want his people to die in one ship, although he has tried his best, but this shortcoming still exists.

Iron armor more than ten centimeters thick, blocking long-range shells is not much of a problem, at close range, it is still easy to be penetrated by solid bullets, after all, the toughness and strength of cast iron plates are limited, and it is difficult to defend at close range.

"Fukura! It's up to you, take the students to be careful, after all, they are not a new army, can they die less, or don't die more! ”

Fighting a war without fear of death is Yang Fuliang's advantage, but taking students to train is a disadvantage.

The cost of training a student in the navy is more than ten times that of the new army, and if you don't become a talent, you will hang up, and the loss will definitely not be small.

"Third master, don't worry, these dolls were all taught by Fuliang, and there are many deaths, and I am also worried!"

I didn't say much, the war was cruel, who lives and who dies. It's not something that Yang Meng can decide. These words. The factors of comfort and encouragement account for the vast majority, and when it is time to go, including him Yang Meng, no one can be greedy for life and afraid of death.

"Hmmm! Let's try it! Pirates should also be distinguished, the lonely souls and wild ghosts who have no backing will be killed first, those who look like they are dressed up as the regular armies of the great powers, just expel them, there is no need to die now! ”

Pirate. Most of them are still regular troops, and the pirates who really dare to fight Pan's idea are not the hands and feet of the merchants of the great powers, and the huge amount of gold and silver in Lixiangyuan is worth the risk of anyone.

The reason why they didn't attack Lixiangyuan was because they knew that there were many defenders of Lixiangyuan, and the mouth of the Pearl River was the place where they were presumptuous, and the warships behind them were the confidence of these pirates.

"Zhilu Dao! I've been touching it all over a long time, some pirates from the Lingding Ocean. has been slaughtered, and the rest are all foreign devils' men and horses. This time, I want to let them float the corpses in the Pearl River Estuary! ”

Sen Ran smiled, Yang Fuliang's eyes also flashed with a fierce light, the door of the house was blocked, and the third master was also beaten by himself, although this Yang Fuliang's wolf nature is big, but the heart of the protector is still there.

"Forget about floating corpses, after they are killed, don't let them drift in the sea, drag them ashore and bury trees!"

Killing foreign devils, as long as they don't come openly, no one will say anything, but if they blatantly kill wantonly, it is likely to make the foreign devils in Guangzhou huddle, which is not a good thing for Yang Meng.

"Hmmm! Zhilu Dao! Drag it ashore to plant a pear tree, this tree can live for a thousand years, so that these bastards will remember our methods within a thousand years! ”

"Good! The pear tree is good, if you kill someone here in the future, you will plant the pear tree, and you can make furniture in the future, just right! ”

Yang Fuliang left with the fleet, and Yang Meng also got on a small steamer and went straight to the iron factory.

"Master, are we going back to Yunnan?"

"Hmmm! Almost, just this month! ”

"What about Madame?"

"Let's stay in Guangzhou for the time being!"

"But ......"

"Don't say it, there are some things that you shouldn't say, you know in your heart! Na Lanying, you can also settle it, after all, you can't bring it back to Yunnan, let her live a stable life! ”

What Wei Zhiqing wanted to say, Yang Meng knew it, but she shouldn't say it, Ding Taichen said that it was a suggestion, and Wei Zhiqing said that it was provoking.

"I know it!"

As a member of the back house, Wei Zhiqing is also the heir what she cares about the most, although she is also looking forward to Mrs. Lian'er's first child being a son, but there are some things that she still needs to be cautious, not that she wants to provoke the relationship between the back house, but just wants to remind Yang Meng.

This kind of thing can only be mentioned to Yang Meng, and it can't be said to others, and if you have a reputation for sowing discord, you can't run away.

Speaking of these sensitive topics, Yang Meng didn't want to go too deep, it was best to perform his own duties, and some people in the back house had better stay away.

I didn't talk much along the way, and after arriving at the iron factory, Li Mingfu hurried to report that the ten-day deadline had passed, and it was time for the iron factory to take things out.

"The result?"

"Fabulous!"

"How many fragments? How big is the impact? ”

"This ......"

When it comes to professional issues, Li Mingfu has no follow-up, it seems that the military industry also needs to get a suitable system, and now the scene of the Yang family is big, but it is messy and unorthodox.

Although many projects are in a hurry, the establishment of a system is also urgent, and it is absolutely impossible to know what it is.

"Mingfu, you are an old man from Xishan Academy, what do you say we still lack?"

didn't talk about the copper cannonball directly, and Yang Meng's question made Li Mingfu, a doer, a little confused.

"Mingfu is stupid, please make it clear to the third master!"

Doing practical things, Li Mingfu has a strong hands-on ability, and some strategic vision of retreat is not what he is good at.

"System! An iron factory is not just an iron factory, there are many things involved in it, physics and chemistry are just the most basic things, think about it, how many things are involved in an iron factory?

A formula comes out, how does this formula come out, why is this formula good to use, and other formulas are not good?

A copper cannonball, for what is better than an iron cannonball, there are some things, you must not only be able to make, but also understand its principle and value.

Without these basic things, you do business, nothing more than painting cats and tigers, you can't learn the essence of others, just blindly imitate, imitate, you will always lag behind others!

Drawing a tiger is not an anti-dog, this is the path you are taking now, and you know why it is true. This is the path that the third master asked you to take. Now you are missing a lot.

Get in touch with Master Ge from Yunnan! Think about what to do in the future. Imitation, imitation, now is a must, what about after learning? Do you have to keep learning from others? Can't we let people follow us?

Four hundred years is a span, two hundred years of the Ming Dynasty, two hundred years of the Qing Dynasty, we fell from the peak to the bottom, in the end because of what, in addition to doing business. That's what you should be thinking about!

For what foreigners can move forward step by step, and for what can we not only not move forward, but also go back more and more? These are the questions!

You Li Mingfu, Tan Yubin of the Ship Master School, and Master Ge of Xishan, you must be the one who leads the tide, not the one who follows the trend!

Take me to try a new type of cannonball! You have to think carefully about my words! ”

Although it is a bit early to innovate and establish its own industrial system, in Yang Meng's view, this is already very backward, whether it is the formula of the iron factory. Or the techniques of the arsenal, many things. It's just on the surface, what is good and what is bad, I am afraid that the three giants who lead Yunnan's scientific and technological progress will not be able to say anything.

"Xie Sanye mentioned, Mingfu has always been troubled by such a problem, after listening to Sanye's statement, Mingfu has a feeling of seeing the sun!"

"Ho! Your sycophant is good, but the third master looks at the result, not how good you say, let's go! Go test the gun! ”

Smiled slightly, it was a response, patting the horse is inevitable, I hope my words can play a role, right?

The test site of the iron factory is very simple, a wasteland overgrown with weeds, and it would be hellish if you could come up with detailed parameters at such a test range!

"This is the test range?"

"Hmm!"

"No, how can you get the lethality of the shell in detail without a target?

Make a wooden target within a radius of 300 steps, clear the grass and trees in this area, after the shell explodes, you have to send someone to pick up the fragments of the shell, and then estimate the lethality of the shell through the damage of the wooden target!

It's not possible to look at the fire from afar!

Thirty test sites were cleared, and fifteen rounds were fired each, and the parameters of the shells came out.

At the same time, you can also experiment with different dosages and the specific range of artillery shells, which is called experimentation and test cannons.

If the conditions of the test site are insufficient, the specific parameters of the copper shells cannot be obtained, and without specific parameters, how can we evaluate the advantages and disadvantages of the copper shells and iron shells?

Let's go down and arrange the venue! In today's matter, you have to reflect in detail, what are you lacking when doing things? ”

Half arrangement, half evaluation, Yang Meng handed over the method to Li Mingfu, as for how far it could develop, he didn't know how to go.

Iron factory, there are no elaborate houses, only ordinary houses, Yang Meng didn't have much requirements for this, found a house that was easy to defend, and stayed.

Due to the hurry of coming, the food here is not as exquisite as the shipyard, but judging from the materials used in the meal, the food here is still not bad.

Li Mingfu also carried out the work overnight to clean up the site and set up wooden targets, and early the next morning, 50 test sites full of wooden targets were built.

"Did you think about it?"

"I think about it, the words of the third master are thought-provoking, this is Mingfu's experience!"

I looked at the things written on a dozen pieces of letterhead, it was very good, and it seemed that my words were not in vain.

"Too thick! There are too many things that need to be refined, so you can change them slowly! And then with Tan Yubin. Master Ge communicated, came up with a detailed plan, and then implemented!

Let's test the gun! ”

The establishment of a system, Yang Meng can only give them a start, and the rest depends on their own development, in which Yang Meng can play a limited role.

The rumbling cannon body sounded, and Yang Meng also tried to take a look at the trajectory, from the trajectory, it was impossible to distinguish the copper and iron shells.

The explosion of the shell on the ground is easy to distinguish, the muffled and small is the iron cannonball, and the crisp and loud is the copper cannonball.

"Is there a dumb fire?"

After waiting for three or five minutes, Yang Meng opened his mouth.

"Nope!"

"Alright, let's go pick up the shards! Also record the extent of damage to the target. ”

The results came out very slowly, and the guns were tested early in the morning, and it was not until sunset that the thirty targets were cleared. It seems that the results of the test will have to wait for tomorrow.

"Mingfu, let me tell you how to analyze the power of the cannonball!

The shell was shot out by the mortar, and it was certainly not very accurate, and the first thing you have to analyze is the damage to the center of the shell explosion and the wooden target.

The second is the power of the shock wave, that is, the center of the explosion, how many wooden targets have fallen, the third is the number of fragments, and the fourth is the enveloping range of fragments.

The power of fifteen shells, the largest and the smallest, is the killing range of the shell, and the average is the killing parameters of the shell! ”

Leaving these problems, Yang Meng Shi Ran returned to his house, and the test was considered a success, just from the explosion of the shell, Yang Meng could judge it.

Early the next morning, Li Mingfu, who had not slept for two nights, came up with the results.

"Third master, the killing range of the iron cannonball is only about thirty steps, and the copper cannonball is eighty steps.

The fragmentation rate, the most iron shells had forty-eight fragments, while the one with the least copper shells had more than one hundred and thirty fragments, and the most one had nearly three hundred! ”

Such a result is not only greater than Li Mingfu's expectations, but also beyond Yang Meng's imagination, thirty steps, that is, forty-five meters, the lethality of the iron cannonball is okay, but the killing range of the copper cannonball eighty steps is a little terrifying, one hundred and thirty meters, this is almost catching up with the range of the rifle, three times the difference, just from the point of view of this killing range, this copper cannonball is worth the price.

The gap between the fragments is even greater, fifty and three hundred, a six-fold difference! Theoretically speaking, it is a copper cannonball, which can kill more than 200 people than an iron cannonball, a terrifying result.

As for the reason why countries don't use copper shells, Yang Meng is also very clear that the cost is a big threshold.

And the biggest embodiment of the role of artillery is still in naval battles, flowering shells are not the main artillery shells, solid shells are, with this conclusion, copper flowering shells, should be manufactured in large quantities.

"When manufacturing in large quantities and using them, you must get my permission to sort out the techniques for making copper cannonballs and send them to Xishan!

In three days, five hundred twenty-four-pounder flowering bombs were made, and I was useful! ”

The experiment of copper flowering bombs was successful, and it was time to set off, Yang Meng did not stay in the iron factory for long, but returned to Lixiang Garden. (To be continued......)
