Li Hang is still very happy that Ying Yun has remembered his tofu theory, and there will be no problem with this subtle influence.

First use sea salt to cut off the financial route of the aftershocks in Tianshui Town, and then wait until something happens in Tianshui Town, and then intervene strongly and end perfectly.

It's just that there is a trouble in doing this, that is, the people in Tianshui Town will be pitted a lot.

At least that's the case for those ordinary residents.

But it doesn't matter much, as long as there is a problem in Tianshui Town, then they can escape.

Chinese people have always had a habit of relying on relatives and friends, and if there is a problem, they can go to relatives for help, just so that they can see the development of the countryside.

When the time comes, once these people settle down, then everything will be easy to say.

Li Hang's ambition is not small, but ambition also needs the cooperation of strength.

It is not enough for a person to have knowledge, it must be disseminated, and one's territory must also have enough economic strength, otherwise it is not a maritime business, even if it is shipping, it needs a lot of money to build a ship, not to mention opening a shipyard and hiring a master to get a lot of wood and anti-corrosion technology.

This is not something that ordinary people can start with.

When running in the river, these boats need to prevent them from soaking, but at sea it is different.

The corrosiveness of sea salt is not ordinarily powerful, and there are many things to consider if you really want to build a sea ship.

But now it's almost winter.

As the so-called eating dumplings in the beginning of winter, there will always be some special benefits for those ordinary people in winter, such as those insects can freeze to death in winter, although it may also include people.

Li Hang frowned, of course this kind of thing is more than that, at this time, no matter how powerful you are, it is common for people to die in winter.

I only hope that after the fire kang becomes popular now, they can die fewer people. "We can do another thing in the winter, so let's all come over if the master carpenter in the workshop is there! There is still one thing in Nongsang's book that has not been completed, and I need your help to verify it! ”

In winter, you need to plan well, just can be used for construction, everyone is nested at home in winter, especially these people in Donglin Port, if the weather in the north is too cold, once the ice is on the water, then this time can only be closed.

After all, there are no ships coming and going, and there is naturally no business at this dock.

Therefore, winter is a time consuming for large-scale construction.

Especially at this time, winter is a good time to test the waterwheel.

There are still very few waterwheels in these years.

Not only waterwheels, but also all kinds of things that can be made, such as rickshaw waterwheels, and water-powered mills.

If you really have enough water power to rely on, you can even make a good device yourself.

Hydraulic forging hammer.

This kind of thing is equivalent to freeing the hands of the blacksmith.

With this thing, the speed at which a blacksmith can craft things can be increased several times.

Especially for some things that are originally time-consuming and labor-intensive, this hydraulic forging hammer can effectively free the hands of these people.

If this time is to go with something else.

This may be able to make steel.

However, if you want to make steel, you have to make coking coal.

Before the Tang Dynasty, the weapons of the Central Plains maintained an advantage over other regions.

Why? Because before it was a fine iron weapon, and then it was steel.

China's iron ore is not the world's high-quality iron ore, not to mention that coal was used to make steel at that time, and there was a large amount of sulfur.

Sulfur and phosphorus are both harmful elements in steelmaking, which need to be removed by reaction, which is what we call dephosphorization and desulfurization.

If you don't master this, going to steelmaking is simply looking for death.

However, it is necessary to make a hydraulic forging hammer and liberate the productive forces.

Ying Yun on the side was curious about what Li Hang was going to do, but Zhao Feilong was not interested.

Looking at his lack of interest, Li Hang laughed instead. "Brother Feilong, if you can help, I can guarantee you that as long as the raw materials are sufficient, I can deliver a thousand sets of such lobster armor to the Daying Dynasty every year."

"A thousand sets?" A thousand sets are enough to arm an army of a thousand people, and it is also an elite army, what a production.

You must know that even those Sizao Mansions in Jinling City do not have such skills.

A thousand sets, it's going to take years.

He did the math a little.

One set is calculated according to ten workers making ten days.

That is to say, if a total of people make one man-hour for one day, a lobster shell is the product of one hundred man-hours. How many man-hours is 1,000 sets...... A lot anyway!

It's definitely not something that can be made in a year.

"If we work together to make this thing, maybe we can have an unbeatable advantage in blacksmithing."

What is a hydraulic forging hammer?

That's a good thing that can top ten craftsmen, and once it is on scale, it can even make a simple machine tool.

Although it is not as powerful as that of later generations, it is at least more reliable than relying on a manual hammer to beat.

What's more, Li Hang has more than one big killer weapon in his hands.

"This hydraulic forging hammer can save the strength of the workers and masters, that is, use water power instead of manpower. In the same way, we can also make some water-powered mills and waterwheels, etc., so that some agricultural and mulberry work such as water diversion and flour grinding can be handed over to water to do, so we don't need to use people or animals to do it. It can even be developed later on hydro threshing, or even some other gadgets. ”

Li Hang touched his chin, in fact, the structure of the waterwheel is not very complicated, the key is how to make it a kind of assembly that can be taken out anytime and anywhere.

Li Hang can draw a rough structural diagram, but it is not enough to have a general structural diagram.

The reason why I want to separate mathematics into science is to promote this thing, how to promote it? From the hands of these craftsmen, of course.

Now the standard ruler and various measuring tools that I have made have been used in attack and defense, at least from the iron bars of these armors, these iron bars are all exactly the same size, not to mention, even the holes above them are a position.

Although these are all ground by the master workers, they are not drilled by drilling machines like later generations.

But because of this, Li Hang feels more precious.

After all, technology was not developed in these days, and many things were made by hand.

This is of course labor-intensive and time-consuming, but it has also cultivated a large number of excellent workers.

It is these workers who have propped up the manufacturing system of the entire Winning Dynasty, and now they are going to start from industry and change everything about this Winning Dynasty!
