The huge waterwheel drove the huge stone mill, and then in front of this huge equipment, the manpower seemed very small, at least the huge stamping hammer on top of it, which the blacksmith could not carry anyway.

This is what Li Hang is ready for.

It is also the best way to use this hydraulic power.

Now I can only use water power, and when a more stable steam engine appears in the future, I can use a more stable neatness.

"There you have this! 10,000 sets of lobster nails a month can be made! As long as there is enough supply of iron ore and fuel, the blacksmith shop here can make Beiping City the largest military fortress and military arsenal in the north! "It's no joke, as long as there are two or three of these huge hydraulic hammers.

You can turn on the military mode to work 24 hours a day, and replace people without stopping labor, so that no matter how unfamiliar you are, no matter how unskilled you are, this kind of armor with simplified craftsmanship can be produced.

And this armor also has a lot of advantages, that is, it can be made of any material.

Whether it is a softer bronze, or the fine iron used today, or steel that has not yet been developed later, it can be made in this way.

Now the hydraulic hammer is complete.

It is entirely possible to make a hydraulic punch by yourself.

In this way, all parts can be stamped directly in one step, which is much faster than manual production.

What's more, there will be mold pouring in the future, so the speed will be faster, and you may be able to design more things.

At that time, all other production will be completely relegated to the back of this new technology, and as long as there are enough materials, it can crush everything that has been blacksmithed in the past.

And it's winter, as long as you find a coal mine over there, you can make a lot of money!

"As long as we find enough fuel, we can start production on a large scale, you now know what I want them to find that kind of thing for, that's why I want to buy those land, in the future, we will not only buy these open-pit coal mines there, but also open mines, not only to transport the ore, but also to make steel here on a large scale, and in the future, all the bronze and iron tools in the Da Ying Dynasty can be replaced with better steel, and even other things can be made from steel, even ships!" Ships made of steel are only a goal, not something that can be achieved in the near future.

After all, it's relatively simple to make weapons and armor made of steel.

After all, surface carburizing and hardening technology appeared very early, such as the steel-clad forging method, which uses pig iron to wrap a part of the steel weapon for forging, so that the carbon element will penetrate into the vicinity of the blade because it is not wrapped, so that the edge will become harder and harder, which will make the weapon sharper.

This kind of small-scale thing that is not so demanding is still easy to make, and when the requirements are higher and higher, the requirements for materials are getting higher and higher, this kind of thing is not easy to make.

Especially in terms of rust prevention, this is the extreme requirement for steel, otherwise it is not as good as some wood.

But then again, how much defense can these wooden sailing ships have now, as long as they can make smoothbore guns, the thick black tube of the solid projectile can pierce and bomb these wooden warships, and the other party has absolutely no power to fight back.

Li Hang picked up the core components of the waterwheel on the side.

"These parts can be made by Jinling City or our people, and then packaged and distributed to every county that has the conditions to build this kind of waterwheel, and only our people need to go down to survey every river. Hydrological surveys are not only a way to determine where waterwheels can be built, but also to predict floods before they come, or even to predict droughts and floods by observing changes in the water levels of these rivers! "Although you may not be able to see the mudslide, you can clearly calculate the amount of water flow by observing the changes in the sediment content and water level in the river.

At that time, as long as the knowledge is popularized, a set of hydrological algorithms, calculating the flow is basically not a problem, once the calculation of this flow is summarized, combined with the water level and the judgment of each position, you can clearly know that the change of water level, thereby affecting the hydrological governance work of each local county and city.

This is a big event in an agrarian society, and from any point of view, hydrological management is a must.

"Now that's interesting! According to what you said, we still have a lot to do! ”

"Of course!" Li Hang had a natural expression.

Whether it is hybrid crops, seed selection, hydrological observations, steel formula experiments, these are long-term and persistent.

No matter what is learned, in the end, it must return to the basic application of the whole country.

This kind of thing must be explained to them clearly.

No matter which of these things is, it is a long-term investment process, but this long-term investment process will have hidden long-term benefits.

In the long run, everyone knows that these plans are good.

But again, these plans have one thing in common, and that is to burn money!

You don't know the physical and chemical properties of a furnace of steel, you have to use experiments to verify its properties, and invest a lot of money in a long-term trial.

How much? How long it is, it's probably the same as the one who made the light bulb.

This kind of thing that doesn't know what to do with it is probably dependent on the sky.

Especially every time something is added, the different amounts will also bring different effects, which is the most sassy.

This kind of irregularity to probe an interesting result is more difficult than opening a box and uncovering Joan of Arc.

This kind of thing is not the most terrible, the most terrible thing is the input.

But don't worry about that now.

First of all, this input can be turned into an output.

After all, this is steel, and even a slight change in physical properties is better than those bronze or animal bones.

At that time, the failure of the experiment is to give it to those peasant uncles, and when the time comes, it will not necessarily be wasted, and at this time, they can turn waste into treasure, as long as the furnace is established, they can even use the slag to make cement on a large scale.

It can be said that if this kind of thing is in the future life, it is estimated that you will have to sell your pants, but in this era, it is your own paradise.

If necessary, once this kind of steam engine is made, you can even get a steam locomotive, or even a suggested railway, even if there is no horse fast, but once you really succeed, and improve these things, you can drag people directly from Beiping County to the border pass, don't tell me what material transportation is, don't tell me what war requires manpower to fight, You can pull a whole car of people over anytime and anywhere, let alone fighting at that time, it will be much easier to develop the north.

However, this steam locomotive still needs too many technology points, and now it is enough to make steel.

"Grandpa Huang will come over the day after tomorrow, I really want him to see these when the time comes! But Li Hang, what's going on with that fighting method? Are you interested in the business of Goshisan? You're not going to eat anything like that, are you? "A high-end aristocrat like Ying Yun, of course, he has seen people who eat five stone powder, and he really doesn't dare to be friends with those people.
