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

It's just that Xia Duo is not satisfied with this price, although this price seems to be lower than the market price, but as a factory price, it is still a little too high.

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

From this, the ideal price given by Chateau is-

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

"Lord Xiaduo, 300 gold coins is absolutely impossible, the ore purchased by the Rayson Leader from the outside is of different quality, plus transportation and beneficiation, it may not be possible to smelt 1 pound of standard Mithril from 3000 pounds, and I can't even cover the cost of 300 gold coins."

In this regard, Xia Duo did not refute it, he knew the situation of the Mithril mine, under normal circumstances, the coarse ore of Mithril ore can only account for about two thousandths of the total amount, which is two thousandths of the total useful ore after rough selection.

And not two thousandths of the total amount of mining work!

In addition, now that Nessera has given up enslaving gnomes as high-quality miners, the cost will rise again, and even if you count the "scraps" such as silver and copper produced in the process of smelting Mithril, it will be difficult for 300 gold coins to cover the full cost.

But since Xia Duo intends to support the growth of the Rayson Lord, then he must have already considered this, "Lord Rayson, don't worry, listen to 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 it consumes, but what if there is a high-capacity air transportation solution that is much 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 Rayson believes me, he might as well take out a rough refining furnace and transform it according to the plan I provided, and if nothing else, it should also be able to reduce some of the costs.

"Combined, even if a standard Mithril sells for 300 gold coins a pound, it is enough to cover most of the cost."

After Xia Duo finished speaking, Lord Rayson was silent, although he didn't quite believe that Lord Xia Duo could provide an effective transformation plan, but the other party said these points were undoubtedly in the direction he was currently working on.

The core area of Nai has long been developed and matured, and after losing a very small number of bandits, it is basically unlikely that there will be any beasts and alien attacks on the road.

But in the future, it is unlikely that all ore will come from the mainland, and Mithril may also be found in new frontiers such as the Plain of Conch, the Abbey Hills, and the Plains of Cologne.

Even if it is only in the mainland, air transport will be more convenient and faster than ground transport.

In terms of beneficiation, the Rayson Leader has already negotiated with some of the Mithril mines, but it was difficult for him to reduce the cost of all aspects before, so he couldn't offer a price that satisfied the local lords.

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

If all that Lord Chado said came true, then many of the problems would not be a problem.

The efficiency is increased and the cost is reduced, even if Xia Duo is given 300 gold coins a pound, what can he do, he still has more output that can be sold to others at a higher price.

"Lord Chador, is what you said true?"

"Of course it's true."

Xia Duo nodded without hesitation, "Regarding air transportation, I don't know if Lord Rayson has ever seen a drifting bottle, a sealed wine bottle filled with air can float on the surface of the water, so if you wrap a gas that is lighter than air, can it be made to float in the air?" If the buoyancy is large enough, can it be used for transportation? ”

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

Flying tools with flying as the core are too difficult to implement, but if you can find a gas that is lighter than air, you don't even need magic to participate in the rest of the steps, except for the one step that encapsulates the gas!

This means that as long as there is enough manpower, it can be replicated indefinitely.

Thinking of this, Lord Rayson hurriedly asked, "Does Lord Xia Duo know how to do it?" ”

In fact, Lord Rayson already has a vague plan in mind, but it is still far from being a practical air vehicle, if there is a mature plan, then he can start the relevant plan immediately.

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

As he spoke, Xia Duo directly projected an imaginary airship image between the two, "I call this tool [Airship], below is a simple flat-bottomed cargo ship, and above is an airbag, and the buoyancy of the airbag drives the cargo ship below to float.

"As for how to move forward, just match a mid-level mage who knows how to fly or make wind, or replace it with a magic item."

"Wonderful, wonderful! The buoyancy of the airbag cancels out the gravity of the cargo below, so that it can even be led by a rope like flying a kite! ”

There is the previous analogy of the drifting bottle, Lord Rayson still doesn't understand, the most important thing about this airship is to use buoyancy to offset gravity, as long as it can float, moving forward or something is just a trivial matter.

At this moment, he couldn't wait to arrange for someone to start the production immediately, but Lord Xia Duo was still here, so he could only hold back his excitement and asked:

"If you only use light gas to drive the cargo ship below, you must need a lot of gas, so where can you find such a big airbag?"

The question was very simple for Shado, who slightly adjusted the projection effect to delve into the airbag above the airship, and explained:

"I don't need such a large single airbag, what I'm showing is just a skin, and the inside is actually made up of a lot of small airbags."

"I see!"

Lord Rayson has already thought of how to make small air bags, and as for the preparation of light gases, it is not difficult, it is more that the process of finding it takes a little time.

This is probably the only place where magic is needed.

"Lord Xia Duo, your airship plan has helped me a lot, I completely agree with the price you just said, 300 gold coins a pound, and never increase the price!"

In fact, airships are not only used to transport ore, or it is a bit wasteful to transport ore, and the value of a shipload of ore is definitely not as good as a shipload of grain or other more valuable goods.

This airship could have been used for so much more.

Lord Rayson made a decision so quickly, Xia Duo was a little surprised, he hadn't said anything about the plan to transform the crude refining furnace!

"Lord Rayson, don't you want a rough refining furnace transformation plan?"
