As we all know, in fact, the history of human development is a history of war and the history of metallurgical development.

Even many historians will divide the development of mankind into primitive eras.

Then came the Stone Age, then the Bronze Age, then the Iron Age, and then the Iron Age.

It can be said that iron tools are the most critical materials and tools in the history of human development.

It is the innovation of this material that has brought about technological improvements.

Technological improvements again and again, and finally brought about the industrial revolution that came to man.

Human beings have been replaced by industrial civilization from thousands of years of agricultural civilization in one fell swoop, and then upgraded into the industrial era again.

The current Falken people are still in an era of intertwined bronze and iron.

In other words, bronze is still widely used in many regions and has not withdrawn from the historical stage.

Iron tools have not yet become widespread!

As for steel, not to mention, there is no shadow yet!

In the smelting of steel, in addition to the ironmaking process, the molten iron is subjected to a process of dephosphorization and decarburization.

At the same time, the materials that are practiced must be continuously forged to make the internal molecular arrangement more uniform, and finally get the desired steel products.

It's just that on Falken, in order to get the corresponding steel, you need a blacksmith to constantly forge the billet.

However, this method of production is extremely inefficient, and the yield is also very low.

This is also the purpose of buying a forging press this time, although the tonnage of the forging equipment is not large, only fifty tons of pressure.

But for that era, it was enough.

The only headache is how to solve the power supply, after all, there is no suitable power supply equipment on Falken.

It is obviously not appropriate to build a thermal power plant.

He and Grande had discussed this before.

And the advice given by Grande is to make good use of the Thousand Mountains Waterfall in Thousand Mountains City.

Speaking of this waterfall, it is actually located in his place, behind Qianshan City, near the palace halfway up the mountain at the eastern foot of Tieshan Mountain.

This waterfall is a dammed lake formed by the melting of snow from the high mountains over there, more than 100 meters higher than his palace.

A gap was formed from the eastern edge of the mountain, and then the water of the lake was slammed down from the summit lake, which was about 500 meters high.

At the foot of the mountain there is also a percussion lake, which then extends into the distance with a river around the mountain.

The river, which he recently named the Biliu River, irrigates hundreds of square meters of pasture in the pastures.

Most of the small lakes in the pastures are formed by this river.

Originally, this waterfall, and the Chongji Lake below, were enclosed by the Gao family, and they made it into a private territory.

This time, Grande consulted with him and wanted him to open up the place.

It was made into an industrial area, because after he inspected the waterfall, he found that it is very rich in water and energy resources.

In this era of energy scarcity, this waterfall can be well used to make a hydroelectric power plant.

And downstream, you can make a steel mill, and at the same time, you can also make a water wheel.

With the waterwheel, you can make rice mills, flour grinders, and many workshops.

Grande's suggestion made Yang Yinuan very moved after listening to it.

Indeed, if this waterfall is used reasonably, then the handicraft industry of their Thousand Mountain City will be able to develop by several leaps.

If nothing else, let's just say that the various leathers produced by this ranch every year can be better utilized.

For example, all kinds of leather robes, leather shoes, leather boots, etc., as well as saddles, stirrups and other horse harnesses.

can be well developed.

So Yang Yinuan didn't think much about it, and agreed to open the waterfall.

Before he left, Grande had already led people to investigate the water conservancy environment in the dammed lake area upstream of the waterfall.

And the construction of the dam has already begun......

So when he went back this time, he had to bring more than that.

There are also a large number of cement, and semi-automatic brick making machines.

With this brick making machine, they can double the production efficiency of the transition.

With those red bricks, many engineering projects can be greatly developed.

At the same time, he also purchased more than a dozen small hydroelectric turbine generator sets.

These small hydroelectric turbines are small hydropower devices that have only been invented in recent years.

The principle of this thing is very simple, it is to dig a few specific waterways on the edge of some small rivers.

Then, in a sharp bay of the waterway, such a generator is set up, and the principle of gravity is important to use.

The feed water flow is accelerated to drive the turbine to rotate to generate electricity.

Very small, very convenient, very suitable for the current Thousand Mountains City.

If these water and electricity equipment are arranged, he will not have to worry about the lack of electricity in the palace on the mountainside.

And once the steel plant below is built, it will not be a few years before all the troops under his command will be able to wear plate armor.

As for any swords, guns, swords, and halberds, they are even less of a problem.

However, the purchase of these is still far from enough for Yang Yinuan.

He sold them all and went to a scrap depot in the distance.

It is not only the workers of the car dismantling factory who can live here, but also tens of thousands of 'craftsmen' who make 'black cars'.

That's right, splicing 'black cars' is also a traditional craft of this generation.

Originally, this area was a scrapped car yard, but later people found business opportunities here.

In the beginning, some small car dealers removed some spare parts from scrapped cars and sold them online to repair factories all over the country.

After all, many car spare parts, if you go to a specialty store to repair, the price is very expensive.

But here, it's only a few hundred dollars.

Later, many people simply removed some usable equipment from those scrapped vehicles, and then started to save their own cars.

Of course, these black cars must not be licensed.

But in rural areas, it can be used to haul some bulk goods, do some farm work, and it is enough.

Therefore, there is still a market in the vast rural areas.

This time, Yang Yinuan came here to make a big purchase, and soon he got a tractor and two pickup trucks.

There are also a few small breads, although they are also cars that are saved later, but they are basically the best of the black cars.

To put it bluntly, the frame is intact, at most the engine removed from other cars is installed on this car.

It's still no problem to run around the countryside!

Out of this, he also purchased a bulldozer waiting to be scrapped, and an excavator.

He doesn't know how to use it, but Grande does!

And this thing, although it was sent for scrapping, can spend some money to overhaul it, and use it for another five or eight years, and there is still no problem.

For him, it's still a great deal......
