Compared with traditional cement pavement, asphalt pavement is more durable and will not crack due to thermal expansion and contraction.

Due to the softness and plasticity of asphalt, it is extremely resistant to external forces.

Moreover, the asphalt pavement is relatively not easy to deform and has strong waterproofness.

For a variety of reasons, this material has become the first choice for road repairs in the Rand.

It's just that asphalt raw materials are relatively scarce in this world, and there is no large-scale mining and mining, only in the west of Kongdu Ling, in the mountains outside Eagle City, this kind of stone has been sold.

Asphalt was used as a binder for building houses as a substitute for expensive mud powder, but Rand knew that asphalt was not suitable for building houses, and that in enclosed spaces, asphalt would produce a faint odor.

Bitumen is a substance that contains trace amounts of toxins, although natural bitumen is the least toxic, but long-term ingestion, can also cause irreversible damage to the human body.

Its most suitable use is to build roads.

And when it comes to mineral asphalt, Rand is well aware of how it is formed.

It is formed by the continuous emergence of oil from the earth's crust, and then stagnation in rocks or mountains, after a long period of evaporation and solidification.

Petroleum.

Petroleum.

Petroleum.

Important things said three times, Rand licked his lips, feeling a little hot in his heart, as a modern person, he no longer needs to be reminded of the importance of oil, this extremely important resource can play a leaping role in the development of industry.

In that world, how many countries did not hesitate to start wars because of this resource, and even paid the whole country's strength, just to get a steady supply of oil.

As long as it is in place, the property and resources lost in the war can be quickly replenished, and the leap at the national level can be completed in just a few years.

Fortunately, the continent has not yet developed to this point, and people have not yet realized that this charred and viscous liquid can contain such great magical power.

That's a cheap rand.

It is likely that there is a resource-rich oil field near or below the mine where rock asphalt was excavated in the western part of the Imperial City.

The method of determining the content of the oil field is also very simple, and it can be estimated based on the amount of asphalt excavated in the mine.

The higher the asphalt production, the more oil must be underneath, otherwise it would not leak so badly.

It seems that it is necessary to take a trip to Eagle City and buy the mine that produces asphalt.

Regarding the resource of oil, Rand does not dare to be careless, and only by keeping it firmly in his own hands can he feel at ease.

Even if you misjudge yourself and there is no oil field under the mine, it is worth buying an asphalt mine alone.

In order to avoid large-scale purchase of asphalt and causing some black-hearted merchants to take the opportunity to increase prices, Rand feels that it is more cost-effective to buy a piece of ore directly.

......

Looking along the banks of the Serra River, the scene on both sides has changed dramatically, and after the barren meadows on both sides were set on fire by the soldiers led by Versailles, the farmers reclaimed a total area of about 300 acres of planting land.

And it's all the most fertile black soil.

Rand divided the land into dozens of portions and distributed them to meritorious soldiers who bravely fended off strong enemies during the winter, which he had promised.

We will not treat anyone who has contributed to the construction of the Air Ferry Territory.

On both sides of the planting plot, simple wooden sheds have already been erected, which are temporary shelters for the farmers responsible for clearing the wasteland, for whom Rand has other arrangements.

Farmers have been with the land since birth, but they have always cultivated the land of the nobles, and after a whole year of hard work, they only get barely enough food to feed their families, and this low reward leads them to become more and more passive in their work, which leads to a decrease in crop yields, and then causes a shortage of food.

There is no doubt that the thoughts of these peasants are that no matter whether they work hard or not, they will get little reward, so why should I work tirelessly for these nobles?

But such laziness is only a whip from the nobles.

Whips and decrees to force farmers to do their work is the stupidest way to do it!

The whip only makes the farmers feel fear and despair of life, and does not contribute to their enthusiasm for work.

The benefits that are imminent in front of the farmer will give the farmers hope.

Rand decided to divide and lease all the land reclaimed outside the wooden house town to farmers, regardless of boundaries and size, and Rand only collected a small amount of rent every year.

The crops that grow from the land are all owned by the growers after they are received.

And the farmers can pay a certain amount of grain to the rand in exchange for ownership of the land!

Although the rand's own interests will be significantly reduced, the grain production of the air ferry territory will increase significantly, and it can even reach the point of self-sufficiency or selling to the outside world.

The production of grain will rise, and at the same time the price will definitely fall, so that at least in the empty ferry territory, there is no need to worry about people starving to death because they cannot afford to buy food.

All of this is just a loss for the rand.

But this loss is nothing to him.

Agriculture is developed just to fill the stomach.

The development of industry is the road to prosperity.

The only way to raise the enthusiasm of the craftsmen and farmers is to give them hope.

They will gradually increase the low production efficiency.

Rand walked downstream along the banks of the Serra River, and saw in the direction of the shallow water in the distance, dozens of craftsmen were erecting a watchtower, which was more like a blockhouse with powerful firepower.

The building is about five meters high, the overall semicircle, the walls are composed of heavy bluestone slabs, just from a distance you can feel this strong defense, in its window, revealing a round hole about fifty centimeters in diameter, from the inside of the pillbox, a black cannon barrel sticks out.

"I'm going to build a pier on the shoal, because the topography gives us a natural advantage where all the boats have to dock and rest. Rand explained to Touron, who was following him, "There are many merchant ships passing through here, but they refuse to stop in the air ferry territory, so I decided to use a forced method to force the merchant ships to dock at the shallow water and trade with the air ferry territory, so as to promote the economic development of the air ferry territory." ”

"We can also use this waterway to transport products, and I've written out plans for the construction of the plant. Later, the smelting plant was renamed as the smelting workshop, and then expanded the assembly workshop, the raw material manufacturing workshop, and the final inspection workshop. ”
