The correct way to open the elf

Chapter 139 Sparks

Feng Yu said in surprise: "There are special metal mines in the Snow Peak Mountains?"

"Where do you think the ore for the alloy tools Clarence made came from?"

Feng Yu suddenly realized and asked, "Is it large-scale?"

“It’s not small, I remember our kingdom was very happy about it for a while, but later we found out that it was a special metal mine, so we gave up large-scale mining.

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

Feng Yu said, "Then you should contact your kingdom immediately and tell them not to sell the ore to the goblins. I will take care of all the ore no matter how much is mined."

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

Feng Yu smiled and said, "I am just occupying a position first. Once I find a way to smelt it, it won't be too late to make large-scale purchases."

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

Feng Yu: “…” He picked up a stone and hit his foot until it was swollen.

As goblin caravans visited the Cattail City camp more and more frequently, Feng Yu had extra workers on hand. He built a number of improved factories, which not only used better steam engines but also replaced them with more sophisticated processing machines.

For example, glass and ceramic factories have added mechanized operation steps to make the entire production process more efficient, freeing up more workers to join the new factories.

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

The magnetite product that had undergone preliminary smelting and was brought back by the supply ship was tested by Feng Yu and was found to have extremely strong magnetism.

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

Including Clarence, everyone thought that Feng Yu was going to use magnets to make new weapons. When Feng Yu was fiddling with the magnets, they all stood around, waiting to help him.

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

The production of thin copper wire is very complicated, but it does not require very high technical content.

In order to produce very thin copper wire, it is necessary to melt high-purity molten copper, then let the molten copper drain out through small holes to cool, and initially make it into 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. The rotation speed of these wheels is slightly faster than that of the other. When the copper wire passes between them, it will be slowly stretched in small amplitudes step by step until it becomes a very thin copper wire.

Although this set of machinery is very large and complicated, the Cattail City camp, with its steam power and gear transmission, has the ability to build it.

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

As for the resin, it is used to brush on the surface of the copper wire to replace the insulating paint. However, it is hard to say whether this thing is effective or not. We can only experiment a little bit at a time. After all, although resin was used as an insulator on Earth before, those were all composite materials.

Feng Yu didn't have the ability, so he could only try it out bit by bit. He was now deeply regretful. If he had known that he would travel through time, he would have learned chemistry and lived a better life. Perhaps he would have achieved modernization by now.

Unfortunately, the professional knowledge he learned, such as programming, is basically of little use compared to primary industries. It is not as effective as what he memorized from browsing forums and watching videos.

Feng Yu carefully wrapped the resin-coated copper wire around the frame that had been made long ago, and then asked Clarence, a welder, to weld the wire ends.

For demonstration purposes, Feng Yu placed a magnet outside as a stator and used a coil as a rotor, so that they could understand more clearly the origin of electricity.

For safety reasons, Feng Yu did not dare to use a steam engine to drive the rotor to rotate at high speed. Who knows if the electronics in the high magic world are the same as those on Earth? To be cautious, Feng Yu used a hand-cranked machine, which at least has a small current and is safer.

The news that Feng Yu used magnets to make new weapons spread quickly 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 research institute came over, waiting to see Feng Yu's new weapons.

Feng Yu looked at the growing crowd and asked, "Why are you all here?"

Clarence said, "You are going to make a new weapon, everyone come and see."

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

Clarence: "Um, aren't you going to make a new weapon out of magnets?"

Feng Yu smiled and said, "So that's why you came here!"

Seeing everyone nodding, Feng Yu said, "Magnets are not used to make new weapons, but to research a new type of power similar to a steam engine."

Clarence said in surprise, "Just using magnets and the copper wires you tied together can make it work like a steam engine?"

Feng Yu smiled and said, "Of course, binding does have magical powers."

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

"There's nothing wrong with that. Let me try it first. Dick, the task of generating electricity is now left to you."

Dick was stunned: "What power generation?"

Feng Yu: "Use AI... Use your hands to crank the handle, faster."

Dick pointed: "Shake this?"

"Yes, you have to shake it in circles, the faster the better."

"That's easy, just watch me!"

Dick grabbed the handle and slowly... started cranking.

Feng Yu was afraid that the speed was not enough, so he used a set of gear changes, which made it not so labor-saving to crank, so he found the muscular Dick.

As the coil rotor in the middle of the magnet painted red and blue slowly accelerated, everyone was confused but stared at the rapidly spinning rotor intently.

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

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

After a slight "pop" sound, the most magical thing of the year happened in the Green Continent. A bright blue arc appeared between the two copper wires, twisting and shining rapidly.

Everyone who was watching Feng Yu's movements cried out in surprise, and then the electric arc disappeared. Feng Yu looked and saw that Dick had put down the crank and stepped back a long way.
