Luo Heng shook his head and said, "No." ”

"It's a genius idea, so that we can sell better weapons. Haradin spoke.

When Luo Heng heard this, he opened his mouth and asked, "Your Excellency, have you noticed that in fact, making white iron daily necessities is more profitable than weapons?"

When Haradin heard this, he nodded and said, "That's right, but we don't want to sell daily necessities, and the blacksmiths in the various noble territories of the human race also need to make money." ”

When Luo Heng heard this, he had nothing to say, why?

Under the power of such local protectionism, any business activity carries a strong political intent.

"It's white iron daily necessities, and we also say that they sell to various noble chambers of commerce. Haradin spoke.

"Cheney, remember, in this world, nothing is free, those greedy, vile, shameless human beings, you know, the price of food, the price of the human principalities adjacent to us is only a third of ours. Haradin spoke.

Luo Heng has long known this, the dwarves produce very little food, especially the dwarves have too much demand for wine, and most of the dwarves' weapons trade every year is exchanged for wine.

Dwarves and humans are stuck with each other, and the amount of food and wine that humans give to dwarves every year is basically exhausted, while the dwarves continue to increase the price of weapons, mainly through limited sales.

So the relationship between humans and dwarves is actually not so harmonious.

Neither side can do without anyone, dwarves can't do without human food, wine, and humans can't do without dwarves' high-quality weapons, otherwise when facing monsters, the weapons forged by humans can't be used at all, and the blood of monsters will have a powerful corrosive effect.

Even the dwarf kingdom is better than the dwarf kingdom, because the combat effectiveness of the dwarf is not as good as the dwarf, so the human race is not very defensive against the dwarf kingdom.

As for the Elven Empire, the correspondence between humans and the Elven Empire is basically the elves taking the initiative, and so far there are no more than a hundred humans who have been to the natural tree of the Elven Empire.

Elven items, in the human world, are sky-high, and the elven empire basically has no material needs for the human world.

Of course, the south where the elves are located, the tropical rainforest full of poisonous insects and beasts, is not suitable for human survival at all.

Haradin's laboratory, not in Fort Furnace, was where Luo Heng saw the hydraulic hammer for the first time.

"It's ....... Luo Heng was surprised.

"This is just an experiment, the cost is too high, the gears, bearings, all need special composite metal, and this forging hammer will cause a lot of dwarves to lose their jobs, once the human blacksmith knows, it will be troublesome. Haradin shrugged his shoulders and spoke, while pouring Luo Heng a large glass of ale.

With a delicate froth, it's clear that this ale is a superb.

Luo Heng couldn't refute this at all, because the various situations in this world were completely different from those on the earth.

"Your Excellency, the flour grinder I designed is ready to be driven by water power, one town and one mill, how many towns are there in the entire human world?" Luo Heng asked.

"Are there any samples, or drawings?" asked Haradin.

Luo Heng took out the sample from the space ring.

"It's a bit expensive. Seeing that it was all metalwork, Haradin spoke.

"Your Excellency, these funnels, and here, and here, can all be replaced with wood. Luo Heng pointed and said.

"Let's see. Haradin spoke.

While assembling it, Luo Heng introduced to Haradin over and over again, the flour grinder was too simple.

But behind the simplicity is the power of high-speed operation, and without this, the flour grinder is also slag.

Haradin pointed to the waterwheel and said, "Do you want to assemble it?"

Luo Heng nodded, and then began to disassemble the hydraulic forging hammer with Haradin.

Seeing that Luo Heng could easily pick up something hundreds of kilometers, Haradin nodded: "It's a great boy." ”

Seeing the accuracy of the hydraulic forging hammer, Luo Heng couldn't bear to look at it directly, this is the technique of the great grandmaster?

After being busy for more than two hours, the hydraulic forging hammer was disassembled, and then replaced with a dough grinding machine, which is smaller than the hydraulic forging hammer.

"I think it's gear-driven. ”

"Actually, the belt link can also be used. ”

Finally, on the power link between the waterwheel and the flour grinder, Luo Heng and Haradin have different opinions.

Opinions are different, the result is very simple, Luo Heng and Haradin have a forge for each person, and Haradin called a few dwarven blacksmiths to help the two, mainly blower equipment.

By the time Luo Heng had cast the pulley, Haradin's gear had not yet completed a third of it.

"You won. Haradin saw that Luo Heng was just making a mold, then pouring and polishing, and it was finished.

Of course, the best pulleys actually need to be forged, just like forging train wheels.

But the flour grinder doesn't need such a high Chen Ben at all.

The belt is also very simple to make, and it is made directly from rope, although there is no rubber in this world, but there is not a lot of gum.

However, the belt made of leather rope is better than that of rubber.

The pulley was pressed, then the belt was installed, and after the brakes of the waterwheel were released, the fixed flour grinder spun rapidly.

Luo Heng brought a hundred catties of wheat and poured it directly, but in half an hour, nine hundred catties of wheat turned into bran and refined flour.

Of course, this small dough grinder is not as good as a large one, but it is enough for this world.

"What is the minimum cost?" asked Haradin, touching the fine flour.

"All are made of castings, but the key parts of the white iron, the rest of the black iron can, I carefully calculated, the minimum can reach two gold coins, according to a thousand pounds of wheat a day, a year is enough to recover the cost, and this grinding disc, can be replaced by a stone mill, but this bearing, a year later is estimated to consume several pairs, but we can trade in the old for the new, earn some processing fees is. Luo Heng said.

"And how about this animal power?" asked Haradin.

"Your Excellency, human beings have windmills and watermills. Luo Heng couldn't smile bitterly. The windmill is actually driving two large stone mills.

"Two gold coins, one town and one ....... Haradin is also estimating.

These are all castings, the cost is greatly reduced, as long as it is not forged, the cost is not very high, for the dwarves, the metal raw materials are stored a lot.

"Can this flour grinder make large ones?" asked Haradin.

"Power, large ones can be manufactured, unless near a big river. Luo Heng pointed out simply.

"Cheney, do you have any blueprints?" asked Haradin.
