The correct way to open the sprite

Feng Yu said in surprise: "There are special metal mines in the Xueding Mountains."

"Otherwise, where do you think the ore for the alloy tools made by Clarence comes from?"

Feng Yu suddenly realized it and said: "Is the scale big?"

"It's not that small. I remember that our kingdom was happy for a while, but later we discovered that it was a special metal mine and gave up large-scale mining.

But that kind of metal ore is very expensive. Except for a small amount of our ore that is supplied to the elves' alchemists, the rest is sold to the goblins in exchange for salt. "

Feng Yu said: "Then contact your kingdom quickly. Don't sell that kind of ore to the goblins. No matter how much is mined, I will cover it all."

Dick smiled and said, "You want to tire Clarence Alchemist to death."

Feng Yu said with a smile: "I just want to occupy a pit first. When I discover the smelting method, it will not be too late to make a large-scale acquisition."

Dick also smiled and said: "Then you need to prepare more money. Since you started supplying cheap salt, the price of the special metal ore sold by the kingdom to the goblins has increased."

Feng Yu: "" Lifting a rock made his foot swollen.

As goblin caravans visited the Cattail City camp more and more frequently, Feng Yu had extra workers on hand, and he built a number of improved factories. Not only did they use better steam engines, they also replaced them with newer equipment. Precision processing machines.

For example, glass and ceramic factories have increased the pace of instrumented operations, making the entire production process more efficient and freeing up more workers to join new factories.

I don't know if it was luck, or Mason's skill points as a master prospector were too full, but the patriarch actually found a flint vein not far from the magnetite.

The magnetite product brought back by the supply ship after preliminary smelting was tested by Feng Yu and found to be very magnetic.

Feng Yu guessed that this thing should not only contain iron elements, but also other elements such as nickel and cobalt similar to the magnetite on earth.

Everyone, including Clarence, thought that Feng Yu was going to use magnets to make new weapons. When Feng Yu was playing with the magnets, they all gathered around, waiting to give him a hand.

As early as Feng Yu knew about magnetite, he had been preparing for this day, making copper wire, and arranging for Dick and Allen to collect many types of natural resin in the Snow Summit Mountains.

The production of fine copper wire is very cumbersome, but it simply does not have a high technical content.

If you want to produce very thin copper wire, you need to smelt high-purity copper water, then let the copper water pass through small holes to cool, and initially make thick copper wire.

The thick copper wire is heated and pressed to form a thick copper wire of uniform thickness, which can be used to stretch the thin copper wire.

Stretching copper wire is to wrap the copper wire around a row of rotating wheels. Each of these wheels rotates slightly faster than the other. When the copper wire passes between them, it will be stretched slowly and slightly step by step. until it becomes a very thin copper wire.

Although this set of machinery is very large and cumbersome, with steam power and gear transmission, the Cattail City Camp already has the ability to build this set of machinery.

Feng Yu built such a copper wire drawing machine in a workshop and pulled out a lot of copper wire. Although it was not as thin as the copper wire in motors on Earth, it was still barely usable.

As for resin, it is used to brush on the surface of copper wires instead of insulating paint. However, it is hard to say whether this thing will work. I can only experiment a little. After all, although resin has been used as insulators in the past on earth, those are composite materials.

Feng Yu didn't have that ability, so he could only do it slowly and bit by bit, trying.He regrets it all now. If he had known that he could travel through time, it would have been great to learn chemistry and come back to work. Maybe he would have been modernized by now.

It's a pity that the professional knowledge such as programming he learned is basically of little use compared to primary industry. It is not as effective as the things he memorized by watching videos on forums.

Feng Yu carefully wrapped the resin-brushed copper wire around the frame that had been made earlier, and then asked Clarence's welder to weld all the wire ends.

For demonstration purposes, Feng Yu placed the magnet outside as the stator, and then used the coil as the rotor. This would allow them to understand the origin of electricity more clearly.

For the sake of safety, Feng Yu did not dare to use a steam engine to drive the rotor to rotate at high speed. Who knows whether the electronics in the high-magic world are the same as those on the earth. To be careful, Feng Yu used a hand-cranked machine, which at least has the same current. Smaller and safer.

The news that Feng Yu used magnets to make new weapons spread like wildfire without his knowledge. Because of the powerful performance of the existing weapons in the camp, all the idle people who were qualified to come to the institute came over, waiting to see Feng Yu's new weapons. .

Feng Yu looked at the growing crowd and said, "Why are everyone here?"

Clarence said: "Aren't you going to make a new weapon? Let's all take a look."

Feng Yu said in surprise: "Who said I was going to make new weapons?"

Clarence: "Well, aren't you going to use magnets to make new weapons?"

Feng Yu said with a smile: "So that's why you came here."

Seeing everyone nodding, Feng Yu said: "The magnets are not used to make new weapons, but to study a new type of power similar to steam engines."

Clarence said in surprise: "Just use a magnet and the copper wire you tied up to make it move like a steam engine."

Feng Yu said with a smile: "Of course, binding has magical power."

Clarence said doubtfully: "Why does it feel like something is wrong?"

"There's nothing wrong. Let me give it a try first. Dick, I'll leave the power generation task to you."

Dick was stunned: "What is generating electricity?"

Feng Yu: "Use the AI ​​to shake the handle faster."

Dick pointed: "Shake this"

"That's right, you have to shake it in circles, the faster the better."

"That's easy, just look at me."

Dick grabbed the crank handle and started shaking it slowly.

Feng Yu was afraid that the speed would not be enough, so he used a set of gears to change the speed. It was not so effortless to shake, so he found Dick, the muscular guy.

As the coil rotor in the middle of the magnet painted red and blue slowly accelerated, although everyone was confused, they all stared at the rapidly rotating rotor.

Feng Yu saw that the rotation speed of the coil rotor had increased, and he used a small dry wooden stick to push one of the output copper wires closer to the other copper wire.

As the copper wire bends, the distance between the two copper wires also gets closer and closer.

After a slight popping sound, the most magical thing of the year happened in the Greenland continent. A bright blue arc appeared between two copper wires, twisting and shining rapidly.

Everyone who was watching Feng Yu's movements screamed in surprise, and then the arc disappeared. Feng Yu took a look and found that Dick had put down the crank in his hand and stepped back a long way.
