In the following month, more than 50 tribes in the Heishui River region almost let the young duke visit them one by one. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Often, these tribes got the news that the little duke was still talking in one tribe in the morning, and in the afternoon they arrived in another tribe.

After all these years, they finally got a taste of being bullied by humans.

The little duke's attitude was very clear, either he would contract the mines in the territory to him, or he would not leave.

Now in the Black Water River, among the five major tribes, the patriarchs of the four major tribes are all detained in the Black Fire Castle.

The remaining Blood Wolf Tribe has formed an alliance with the Black Fire Castle, and the Iron Back and Iron Claw father and son have become famous on many occasions and have advanced and retreated with the Duke.

This made those small and medium-sized tribes dumbfounded, no one stood up to take the lead, how to resist the fierce Black Fire Family?

Moreover, others are not occupying the mine for nothing, willing to pay rent, and provide jobs.

These tribes have all handed over the mines in their territories and let humans settle in.

After tasting the sweetness, the tribes without mines looked at the tribes whose quality of life had improved significantly, and protested.

On the one hand, Lin Ye sent Qiqi to set up a working group to survey mineral resources in the Heishui River area, and on the other hand, he assured these tribes that the Heihuo family had the obligation to lead the brother tribes in the Heishui River area to a well-off life.

He promised to provide jobs for all orcs and free them from the life of fishing and hunting.

This won the cheers of the orcs.

It turns out that humans are not here to plunder, but to send warmth.

It touched them.

In just one month, the Black Fire Family has successively received 12 mines.

Among them, there are 4 coal mines, 5 iron mines, 2 gem mines, and 1 mythril mine.

Although the scale of these mines is not as large as that of Panshan Coal Mine, with the current capacity of Blackfire Castle, it can basically maintain the mining of 13 mines.

After all, the labor force comes from the local orc tribe in the form of employment.

They are underutilized of these minerals and have significant technical deficiencies.

And Lin Ye's vision and the technology brought by Bachi make up for this very well.

At the same time, Lin Ye and Eight Feet also worked out some prototypes of mining equipment and laid wooden rails in the mine.

In this way, mining efficiency can be significantly improved.

But Lin Ye was still not satisfied with this.

Because he is still waiting for something that has the significance of the transformation of the times.

That is, the power machine that sounded the horn of the industrial revolution, the steam engine.

"The so-called steam is when boiling water, when the water boils the power that is enough to lift the lid, just such a small kettle can achieve this effect, expand the kettle dozens of times, how much should the kinetic energy increase?"

Lin Ye was demonstrating in the square, and when the water boiled, the boiling steam washed the lid out.

Everyone was dumbfounded, and none of them understood the complicated words that the Duke had said.

Only the dwarf led by eight feet probably understood seven, seven, eight, eight.

"But the steam is so hot that there is no way to get close to it, how are we going to master this kinetic energy?" said Eight Feet Fee.

The power of steam is not to be underestimated, but the key lies in how it is used.

He couldn't find a way to restrain that force.

"We control the steam in a solid and enclosed space, which we call the 'cylinder', which is connected to the 'piston', which you can understand as something like a gear, like a pinion driving a large gear. ”

"The kinetic energy provided by the steam will drive the piston, make it start to run, carry out the piston movement, and the piston movement will drive the operation of the bearing, and the amplified kinetic energy can be applied to various fields through various machinery, and the general principle is like this. Lin Ye explained.

"But according to what you said, only high temperature can ensure that the steam can promote the vitality and make the piston move, so what if the steam cools down?"

"The cooled steam is re-condensed into water, which is discharged through pipes, which in turn are controlled by valves, and the boiler is connected to the valves through the inlet pipes, which create a reciprocating kinetic energy system. Lin Ye continued to explain.

"And how do you make such a steam engine?"

"This is the drawing, we already have the coal to provide energy, but the poor is the steel of sufficient quality, and the welding technology, which is the trickiest part. Lin Ye frowned.

He learned the principles of the steam engine when he was in junior high school, and there were drawings of the steam engine in textbooks at that time.

It's not hard to draw from memory.

The difficulty lies in the welding technology.

"Well, what is welding?" asked Eight Feet in a whisper.

He had thought that his engineering skills were enough, and that even among the dwarves, he was a superior being.

But now compared to the little duke in front of him, he felt as if he was still an apprentice.

Especially the hands that are exposed where the bricks and cement are burned.

It can simply set off a revolution in engineering and construction!

Now it's time for the steam engine, which he doesn't quite understand, and what kind of welding is there.

He really didn't understand, so he could only humbly ask for advice.

"Welding is the seamless joining of two pieces of iron, which requires not only very high temperatures, but also very delicate techniques, which is really difficult to do without kinetic energy and tools. ”

"Did you forget something?" asked Eight Feet with a sudden grin.

"What?"

"Fire Crystal, if you use its power, there will be absolutely no problem with the welding you mentioned. "Eight feet of promise.

"The magic crystal that Undercurrent Island brought back? I was planning to use it to build a kinetic energy system. Lin Ye fell into thought.

But soon he and Hachiku discussed the possibility of using the Fire Crystal for welding.

After much discussion, it was decided to let Eight Feet test first.

It's just that the iron ore mined now is really limited and has not yet been transported, and refining steel is also a process.

Everything can only be done gradually.

Ababa was very interested in the development of Castle Blackfire, which included brewing, papermaking, farming, mining, steel refining, and the steam engine being developed.

As a businessman, he had a natural sense of smell, and he could already see the mountains of gold and silver hidden in the Far East.

However, he was not able to stay long in Blackfire Castle, often staying for a week before being sent to sea to continue trading.

The number of ships he took with him gradually grew from the first two to three, four, and then to six.

There are also more and more third-party ships arriving at the port, and the abandoned port is no longer enough to handle such a large flow of goods and the needs of merchants.

The construction of the port also had to be put on the agenda.

"These businessmen are eyeing the fat of the Far East, and it is not possible to make money from me so easily, it seems that after the port is completed, it will be necessary to open a new industry in the port. Lin Ye groaned with his fingers.

"What's your idea?" asked Yuffie with a smile.

"Opening a gambling business, our Black Fire family's money is not so easy to earn. Lin Ye said with a smile.
