Seeing that Xia Duo did not insist on the issue of measurement standards, Lord Leisen also made some concessions and offered to reduce the purchase price to 500 gold coins per pound.

However, Xia Duo was not satisfied with this price. Although the price seemed to be lower than the market price, it was still a bit too high as an ex-factory price.

What's more, what he gave is a long-term order, which is enough for Leisenling to lower the purchase price in foreign ore purchases, and can also use this order to improve the process and reduce costs.

Therefore, the ideal price given by Xia Duo is—

"300 gold coins a pound, I think it's more reasonable!"

"Lord Xiaduo, 300 gold coins is absolutely impossible. The quality of the ore purchased by Leisenling from outside is different. In addition to transportation and beneficiation, 3000 pounds may not be able to smelt 1 pound of standard Mithril. I can't even cover the cost of 300 gold coins." .”

To this, Xia Duo did not refute. He knew the situation of the Mithril mine. Under normal circumstances, the rough Mithril ore can only account for about 2/1000 of the total amount, which is the total amount of useful ore after rough selection. Two thousandths of the amount.

Instead of two thousandths of the total mining project!

In addition, the current Netheril has given up enslaving high-quality miners such as dwarves, and the cost will rise again. Even if the "waste" such as silver and copper produced during the mithril smelting process is included, 300 gold coins can hardly cover the full cost.

But since Xia Duo intends to support the growth of the Leisen Territory, he must have considered this, "Lord Leisen, don't worry, let me explain to you.

"First of all, in terms of transportation, the biggest cost comes from time, fleets, escorts, transit fees, etc. The longer the time, the more consumption, but what if there is a large-capacity air transportation solution that is faster than the ground?

"Secondly, in terms of mineral processing, it can be carried out locally first, which reduces the work on your side, and secondly, it can also reduce the cost of transportation.

"In terms of smelting, if Lord Leisen believes in me, he might as well take out a rough refining furnace and modify it according to the plan I provided. If there is no accident, it should also reduce part of the cost.

"Together with the above, even if the standard Mithril is sold for 300 gold coins per pound, it is enough to cover most of the cost."

After Xia Duo finished speaking, Lord Leisen remained silent. Although he did not believe that Lord Xia Duo could provide an effective transformation plan, the points the other party said were undoubtedly in the direction of his current efforts.

The core area of ​​Nether has been developed and matured a long time ago. After losing a very small number of robbers, it is basically unlikely that there will be any wild beasts or alien attacks on the road.

But in the future, it is impossible for all the ores to come from the mainland, and mithril mines may also be found in newly developed places such as the Kangqi Plain, the Abby Hills, and the Cologne Plain.

Even in the interior, air transportation will be more convenient and faster than ground transportation.

In terms of mineral processing, Leisenling is already negotiating with some Mithril mines, but it was difficult for him to reduce the cost of various aspects before, so he couldn't offer a price that satisfied the local lord.

In addition, Leisenling is not the only company in the mainland who intends to integrate Mithril resources and develop Mithril smelting industry, and competition will also bring higher costs.

If all what Lord Xiaduo said is realized, then many problems will not be problems.

Efficiency increases and cost decreases, so what if Xia Duo is given 300 gold coins per pound, he still has more output that can be sold to others at a higher price.

"Lord Xia Duo, is everything you said true?"

"of course it's true."

Xia Duo nodded without hesitation, "About air transportation, I don't know if Lord Leisen has ever seen a drift bottle. A sealed wine bottle filled with air can float on the water. If you wrap a gas that is lighter than air, Can it float in the air? If it is buoyant enough, can it be used for transportation?"

"Buoyancy?" Lord Leisen's eyes suddenly lit up. He had only considered the flying technique before, and he had never thought of such a simple plan.

It is too difficult to realize the flying tool with flying technique as the core, but if you can find a gas that is lighter than air, except for the step of wrapping the gas, the rest of the steps don't even need magic to participate!

This means that as long as there is enough manpower, it can be copied infinitely.

Thinking of this, Lord Leisen asked quickly: "Does Lord Xiaduo know what to do?"

In fact, Lord Leisen already has a vague plan in mind, but it is still far from a practical air vehicle. If he can have a mature plan, then he can start related plans immediately.

"Of course, since I said it, there must be a plan!"

As he said that, Xia Duo directly projected an image of the airship in his imagination between the two of them, "I call this tool [airship], the bottom is a simple flat-bottomed cargo ship, and the top is an airbag, using the buoyancy of the airbag Drive the cargo ship below to float.

"As for how to move forward, you only need to be equipped with a mid-level mage who knows the flying or wind spells, or use magic items instead."

"Wonderful, wonderful! The buoyancy of the airbag counteracts the gravity of the cargo below. In this way, it can even be led by a rope like flying a kite!"

With the analogy of the drifting bottle before, Lord Leisen didn't understand that the most important thing about this airship is to use buoyancy to counteract gravity. As long as it can float, moving forward is just a trivial matter.

At this moment, he wished he could arrange for people to start production immediately, but Lord Xia Duo was still here, so he could only suppress his excitement and asked again:

"Using only light gas to drive the cargo ship below must require a lot of gas. Where can we find such a large airbag?"

For Xia Duo, this question is very simple. He slightly adjusted the projection effect, and extended the angle of view deep into the airbag above the airship, and explained:

"There is no need for such a large single airbag. What I have shown is only the skin, and the interior is actually composed of a large number of small airbags~lightnovelpub.net~ So it is like this!"

Lord Leisen has already thought of how to make a small airbag. As for the preparation of light gas, it is not difficult, but the process of finding it takes a little time.

This is probably the only place where magic is needed.

"Lord Xiaduo, your airship plan has helped me a lot. I completely agree with the price you just said, 300 gold coins per pound, and the price will never be raised!"

In fact, the airship is not only used to transport ore, or it is a bit wasteful to transport ore. The value of a ship of ore is definitely not as good as a ship of grain or other more valuable goods.

This airship could have more uses.

Xia Duo was a little surprised that Lord Leisen made a decision so quickly. He hasn't mentioned the plan to transform the rough refining furnace yet!

"Lord Leisen doesn't want the refining furnace modification plan?"
