If you want to fight these tough tribesmen, if it's a regular army, it's okay.

Use effective equipment to engage in tug-of-war with these tribesmen.

But what if it's a traveling caravan and you run into these guys in the wild?

That's when the role of the barbed wire comes in.

Just make a circle around the perimeter of the camp and temporarily tie such a circle of barbed wire, which can double their defense!

And with the barbed wire, it also greatly strengthens the sense of locality of the camp.

Once something happens, it won't be like a fly for everyone.

This thing can definitely be used as a safety barrier for field marches.

Even in Yang Yinuan's opinion, the effect of this thing is safer and more effective than those camps where the local aborigines marched and camped.

And it's easy to disassemble and assemble, so when you set up camp at night, you can make a circle around the camp.

When you go during the day, dig out the stakes and roll up the barbed wire, and you can take them directly.

There's really no more convenient defensive artifact than this thing.

So this time when he came back, Grande strongly recommended that he purchase two wire drawing machines.

This thing may not be remarkable until now, but if you get the Falken Star, it will definitely be an epoch-making invention.

Not only can it increase productivity, but it can also play a significant role in the military.

And with the wire drawing machine, then the next step of reinforced concrete building is not far away.

After all, the first generation of steel-concrete buildings on the Blue Star were derived from barbed wire......

It is said that a blast furnace colonist, in his plantation, researched how to make the barrels planted with palm trees stronger.

Barbed wire was placed next to the barrel and cement slurry was poured into it.

The result is a first-generation reinforced concrete element that is exceptionally strong.

Since then, a large number of reinforced concrete structures have been born.

As for Falken Star, Yang Yinuan doesn't seem to need it much at present.

After all, they are so short of iron, even though he 'purchases' almost ten tons of scrap steel from the recycling station.

But even if all these scrap steel are re-smelted, it will only be enough for the production materials in Qianshan City.

If you want to use it to make steel bar, it would be a bit too extravagant.

Speaking of the various agricultural tools used by each household, these iron may not be enough!

Therefore, the reinforced concrete may have to be slowed down.

These two wire drawing machines cost him a total of 100,000 yuan.

Originally, he planned to buy a few second-hand goods, but later checked on the Internet, and the new ones were only 50,000.

I simply ordered two units first and took them to the other world to try.

If the machines purchased this time are easy to use, then we will purchase a few more next time.

And after this thing is there, the city wall will be repaired in the future, and then some barbed wire fences will be placed on the outer part of the city wall.

Hehe, even if they come with 300,000 coalition troops next time, don't even think about breaking through the walls of Thousand Mountain City.

Of course, in addition to these two wire drawing machines, he also purchased some other equipment.

For example, brick making machine......

As the people of Qianshan City discovered the benefits of this red brick, this red brick suddenly became one of the most sought-after goods in Qianshan City.

Because it's so easy to use!

In these years, the local aborigines built houses, which were generally in the form of several forms.

Wealthy people such as Yang Yinuan lived in castles built of stone.

The castle is so strong that it will not be a problem to live in for hundreds of years.

For ordinary people, most of them live in thatched huts or wooden houses.

Many people can't even afford to live in wooden houses, even though the planet is full of towering trees hundreds of meters high.

There is no shortage of forest resources, but the problem is that the cost of going up the mountain to cut down trees is very high.

With such tall trees, it is not a simple job to cut them down and transport them.

So cut down the trees, then transport them down the hill and cut them into logs or planks of various shapes depending on the house you want to build.

It takes a lot of time, manpower and resources.

With the productivity of that era, sometimes it took one to two years to build a decent wooden house.

So where are people going to live during this time?

I can only live in a hole dug in the ground, which is cold and damp, not to mention the quality of life.

Of course, there are also people who live in stone houses and thatched huts with mud walls and thatched roofs.

However, these two kinds of houses also have their own drawbacks, stone houses are difficult to find consumables, the cost is high, and ordinary people cannot afford to live in them.

Although the thatched house is easy to build, the problem is that it is not strong.

Once it rains heavily in the summer, your mud wall may collapse after being soaked in rainwater for a few days, and it is easy to breed snakes, rats, insects and ants inside.

The most important thing is that this house, in the winter he does not keep warm......

Therefore, how to build a strong, durable, safe and warm house has always been the most headache for the local natives.

And with the advent of red bricks, a new building material, those natives suddenly found that the problems that plagued them were solved at once.

This kind of red brick is strong and durable, and it is inexpensive.

After firing, the speed of building a house with red bricks will be very fast, as long as it is built layer by layer.

If there are enough people, in a few days, you can build a house out of these red bricks.

Moreover, this kind of house is also very strong, and if the walls are thicker, it is not a problem to prevent wind and keep warm.

In this way, this red brick has become the most sought-after material in Qianshan City.

Although a large number of red bricks are now produced every day, they are sent to the city wall, and they are ready to continue to build the city wall after the beginning of spring.

But there are still countless ordinary people who are guarding the surroundings of the transition every day.

Hopefully get some extra quotas.

Because every day after the brick factory opens the kiln, there will be some defective products.

First-class good bricks are naturally the first to be assigned to municipal projects.

For example, the construction of the city wall, or the construction of factories in the industrial zone at the foot of the West Mountain.

And some second-class products, and third-class products, will flow into the private market.

Some free people in the city who have a small amount of assets, or officers who have become officers of the Thousand Mountains Army, will try their best to purchase a batch.

Although it may not be enough to build a house, it will accumulate after purchasing it, and sooner or later it will be enough!

Even every time the kiln comes out, there will be a batch of scrapped bricks.

It will also be snapped up by the citizens of Thousand Mountain City.

Those defective bricks are generally in the process of firing, because the mud is not broken, and the hard core is produced.

Or it is deformed, cracked, or damaged during the firing process.

These bricks are naturally substandard for the construction of city walls and industrial areas.

Even to a lot of wealthy freedmen, they don't look down on them.

But for those poor people, what more bicycles!
