"Yes, artillery is indeed a good idea, have you developed it?" Huo Gang asked with some curiosity, and he didn't say much extra words.

"Not yet, the main thing is that we now have some doubts about the material of the barrel and how to place the gunpowder, and we are still experimenting." Chen Min scratched his head and said with some embarrassment.

"I have some ideas for this, such as making a cannon barrel, in the tail of the barrel can make a valve, first load the shell, then stuff the fixed gunpowder into it, and then use the fire wire to ignite it, and close the valve at the back similar to the stove." Huo Gang probably talked about the simplest way to fire shells in ancient times.

Or to be precise, this should also be the way most cannons are fired in later generations, but the choice of breech guns means that there are many technologies to be solved, but I have to say that the emergence of Huo Gang has not only brought great progress in the steelmaking industry, but also includes hydraulic die forging casting and free forging casting.

Especially after the use of steam power, the technology of hydraulics has made continuous progress, I don't know if it is because Lu Feng was the first to contact hydraulic technology, which has made them really produce many inventions in this regard, especially now using steam-powered hydraulic presses, which are faster than before, and the steel castings that can be forged are also larger.

The normal development of science and technology in later generations, whether it was the first to develop hydraulic forging or the first to develop a cannon or something like that, Huo Gang didn't know, but in his case hydraulic pressure appeared first, especially this can be regarded as a way to open the wisdom of Lu Feng and Sun Er.

This is what leads them to have extraordinary acumen and motivation and interest in this regard, and when Huo Gang told them that these hydraulics can reach tens of thousands of tons, or even 100,000 tons, they were even more excited.

Officially, because of the continuous progress of technology in this area, the steel quality of some large castings in Huo Gang's territory is getting better and better! So come up with the barrel...... It really couldn't be easier.

To be honest, such a development direction always feels weird, but Huo Gang doesn't bother to tell how strange it is, anyway, he remembers everything he can think of in his mind, as for which of these things originally appeared first and which appeared later, where did Huo Gang remember so much.

As long as it doesn't affect their development, isn't it?

Huo Gang told Chen Min about the way the breech gun was talked, and as for the closed way of the breech gun bolt, Huo Gang forgot that there seemed to be any wedge-shaped bolt and spiral bolt when he arrived, and Huo Gang didn't know much about it, so he simply told them.

Screws, bolts can now be made, so these are not a problem, at present, the industrial city has preliminarily researched the most basic lathes, these lathes are not what Huo Gang told them, Huo Gang has studied other aspects, but in terms of machine tools, Huo Gang really has not studied.

How did these basic machine tools come out? Quite simply, use the wisdom of the ancients.

To be precise, ancient Chinese carpenters have long studied devices similar to simple machine tools, but such devices are more used in woodworking, and machine tools are nothing more than turning these woodworking machine tools into finished steel products, and then making it more reasonable to process various steel parts.

This thing has been designed a lot, and Huo Gang has even given them the concept of an assembly line, including how to make these machine tools use steam power, so that they can be made more accurate and fast, and Huo Gang has given hints.

As for what can be developed, Huo Gang is not very clear, follow-up research and development, Huo Gang can't do anything, if you say that he stays here every day, then these things must be improved, Huo Gang's knowledge in later generations alone can provide a lot of creativity.

But this is actually not a very good thing, don't look at the industrialization of the Han Dynasty has just started, in fact, this time, it is the time to cultivate the spirit of craftsmen and the spirit of research.

And although Sun Er's group of craftsmen has not gone through systematic learning, but in this era to become the best among the craftsmen, it requires extremely smart brains, so as long as they are willing to study, no matter what kind of results they produce, all the things they summarize are valuable experience and wealth.

Huo Gang said these words, Chen Min's eyes directly lit up and let people record all of them, and after recording them, Chen Min opened his mouth and asked, "Chief, do you want to go and see the effect of gunpowder?" ”

"I won't look at this, but you should pay attention to one thing, the formula of gunpowder is strictly confidential, and the second is that the various raw materials of gunpowder must be safe when stored, this is what you personally matched, you should know how powerful this thing is."

"And then there's your lab, although I want you to have a variety of products, but remember, your life is the most precious thing, knowledge is in your head, and only if you keep this knowledge alive, that is the real wealth. Like these other things, I tell you, as long as you can buy them with money, that's not a problem! ”

"Yes!" Chen Min agreed in a solemn tone, and only the leader would attach so much importance to the status of these people.

"Well, that's good, so be it, as a weapons research institute, it's not good if you don't have a goal, your goal is to research this breech gun, of course, if you research other products that can be used, you can also leave it and make a simple introduction booklet for me."

"As for the gunpowder, the bulk gunpowder can be effective, but if the gunpowder is sealed into a cylindrical powder keg, and then the shells are placed in front of it, then the loading speed will be faster in actual combat, and the amount of gunpowder will not be mistaken, these will need to be tested by you." Huo Gang said.

"Yes!"

"Well, your main research goals are two, one is artillery, and the other is smokeless gunpowder, that is, nitrocellulose, that thing you have experimented and made into a little bit, if it is industrialized and large-scale, you have to study it."

"I remember to keep all the research materials during the whole process."

"Understood."

"Then I won't bother you and go." Huo Gang smiled and waved his hand, and left here directly.

After leaving here, Huo Gang was somewhat excited, he felt that he had fallen into a misunderstanding, and it can't be said to be a misunderstanding, from a modern person's point of view, in his subconscious, the technical level of flintlock pistols, arquebuses, and even Mauser series rifles is far lower than that of artillery.

But that's modern artillery!

In fact, in the beginning, the difficulty of making artillery was much lower than these guns, and in history, there were first artillery, and then people were inspired by artillery to start making guns.

After all, artillery is huge, and this thing is of course much simpler to make than a firearm.

If there is artillery, I dare not say anything else, in this era, Huo Gang officially declared invincible.

Because it's very simple, the truth is within the range of the cannon, and the problem in this era is to attack the city for the forces of Huo Gang, which is dominated by cavalry, but with artillery, unless all the city walls are like the walls of Yumen Pass, otherwise, the city walls of this era cannot stop the footsteps of artillery at all.

What is even more terrifying is that the deterrent power of artillery is invincible in this era. In the face of such a thing, the people of this era are simply the punishment of heaven, I am afraid that it will not take a few cannons, and the people in the city will surrender, although it is still very troublesome to transport, but this deterrent is like a nuclear weapon in later generations, of course, it must be developed.

Moreover, Huo Gang believed that with the current strength of the Industrial City, it would not be long before the first batch of artillery could be produced.

Leaving the Weapons Research Institute, Huo Gang said to Yang Wu next to him: "How did you decide on the plan to establish a commercial house here in the Industrial City?" ”

Huo Gang just put forward an opinion on this matter, as for how to implement it, Huo Gang did not participate, these are the Ministry of Industry's own restructuring pilots, depending on their own ideas, but it is still okay to ask them.

"We have discussed several plans so far, the most critical of which is the study of follow-up technology, whether the cabinet will give financial support." Yang Wu immediately opened his mouth and said, before the establishment of the cabinet, a decision had been made, and Huo Gang's own private treasury was originally temporary, or to be precise, the private property and treasury of the royal family in the future would naturally be separated.

It's like Datang's inner treasury and the national treasury are also separated.

But considering the actual situation of the Han now, the previous opinion of the cabinet was that for the time being, Huo Gang could use all the funds of the treasury, whatever Huo Gang did, after all, everything in the entire Han was developed by Huo Gang.

But it is not good to have a specific figure in this way, and later Huo Gang himself set a ratio, one-tenth of the annual treasury revenue, directly in the central bank to a separate account, which belongs to Huo Gang's private property.

As for how this proportion should be reduced in the future, or how the two sides should be independent, we will talk about it later.

The reason for setting a tenth is that if the figure is too small, the cabinet does not agree. In their opinion, everything is Huo Gang's can be said in the past, and one-tenth is already too little, if it is less, they will not agree.

One tenth Huo Gang thought about it later, it's okay to ask for it, it's a big deal, when the time comes, he can find a way to do education by himself, anyway, education is a bottomless pit.

After the separation of finance, some of the government's actions are naturally to ask the government for financial allocation, and the current demand for funds in this area is naturally the largest in the industrial city.
