Jin began to explain to Ernst II how to reduce the price of materials.

"You say that materials are rising in price, but I think we need to know what percentage of that price they represent."

"Mm."

"Now take the Magi Crystal (Magi Crystal) in this country as an example, ......Daiki, explain it to me."

At this point, Jin assigned the role to Daikin.

"Yes. The transportation and mining costs account for more than two-thirds of the total. Of these, mining costs account for 70%.

"Ummm ......"

That means that nearly half of the price is for mining.

Daiki is a meticulous person, and he knew exactly what these figures meant.

However, what he could not do beyond that point, that is, until he took measures, was compensated by Jin.

"So..."

Now it was Jin's turn.

"What I can do is to lower the cost of mining.

Jin said that by using the golem, the labor cost could be reduced.

"That's true, but you'll need materials for that," said Legray.

said Mr. LeGray, Minister of Magical Technology.

"In other words, in order to reduce labor costs, we need a golem, and in order to prepare a golem, we need materials. And the price of those materials is rising.

"I understand. That's why we are ."

"You mean 'rent'. But at the moment, every country is short of manpower and golems to rebuild the country that has been torn apart by the <>.

"Countries are, aren't they?"

Jin chuckled at that. Ernst II immediately understood the meaning of that laugh.

"So you're telling me that you have a ...... for Jin-dono?"

Yes, I have enough golems to lend you.

"Oh, ......!"

This is the purpose of this visit.

To rent out the Golem needed to make up for the lack of labor at a reasonable price, or to sell it in installments.

Jin is willing to do either.

"The level is equal to this Hope."

Here, refers to the performance during the demonstration in <>, which is actually 30 percent of its capability.

But even so, it is certainly an outstanding ability in today's world.

Mining with golems eliminates the need for ventilation in the tunnels, which saves a lot of time and effort.

I can lend you 20 of them. What would you like to do?

"Of course."

Ernst II replied immediately.

"But I would like to know how much it would cost before I decide whether to lend them to you or to purchase them in installments. How much would that be?"

"Uh, ......."

Jin became impatient. He had forgotten to set the amount. As usual, Jin was not good at keeping track of money.

"For a loaner, it is 1,000 dollars per month, and for a one-year contract, it is 10,000 dollars. If it is a one-year contract, it is 10,000 dollars. If you want to pay in installments, you can pay 3,000 dollars per month in 50 installments.

Reiko answered on behalf of Jin. The old man had contacted her through the manacam.

"What!　...... is cheap."

If one tol is equivalent to about 10 yen, a rental is 10,000 yen per month, or 100,000 yen per year for a yearly contract.

If paid in installments, the monthly rent would be 30,000 yen, or 1.5 million yen for 50 installments.

"Of course, it doesn't mean that you can only mine ore."

The golem that Jin makes can easily handle the clerical work.

This was something we had all seen demonstrated at , so we were immediately convinced.

In the end, the Finance Minister and the Minister of Internal Affairs and Communications were asked to join in the discussion, and a conclusion was reached the next day.

* * * * * * * *

Jin's proposal is not over yet.

"Now all that's left is transportation."

"Mm."

Whether from the mines of the former Leonard Kingdom or from domestic mines, the cost of transportation would be considerable.

"So here's my proposal. <

"That's certainly true, but ......"

In the case of metals, there is a difference in efficiency between transporting ores and transporting refined metals.

For example, the iron content of the best iron ores, <> is said to be 70 percent, <> is 72 percent, and the average including other iron ores is about 65 percent. The average including other iron ores is about 65%.

In other words, 35% of the weight is superfluous.

When it comes to gold, the content drops dramatically.

As an example in Japan, the ore from the Hishikari Mine in Kagoshima Prefecture contains a maximum of 290 grams of gold per ton and an average of 50 grams per ton. The average amount of gold in a ton of ore is 50 grams.

Since the profitable content of gold is 5 grams per ton, it is easy to understand how large the content is in the case of gold.

For this reason, it is desirable to set up a refinery as close to the mining area as possible.

Currently, refineries are built on the outskirts of towns a short distance away from the mountains where the mines are located, and it is a considerable amount of work just to transport the ore to the refineries.

In the case of Ars, magic and magical engineering are available.

Jin offered to lend them a more efficient refining machine (magi-machine).

"That would be great!"

Jin said, "I would like to receive one percent of the metal refined by each of these machines as a royalty.

"Is such a small amount enough?"

Ernst II made an immediate decision on this matter, but seemed to be concerned because it was so little.

"Yes, that's fine. But there is one more thing. I would like to receive free of charge any trace elements contained in the tailings that you would like to have.

"Of course, that's fine."

For example, silver ore <> often contains antimony, and <> is a sulfide mineral of silver and antimony.

Bismuth, which has been attracting attention in recent years for its beautiful crystals, is often extracted together with adamantite from the als.

Jin wanted to stockpile these metals rather than dispose of them as tailings, anticipating that their demand would eventually increase as their uses are recognized.

* * * * *

"First of all, everything went well.

After the negotiations in Miyagi, Jin returned to his residence and relaxed.

"Father, thank you for your hard work.

Jin sighed with relief as he drank the tea Reiko had made for him.

"Ah, the tea is so good."

Jin gazed out the window at the sky as it was getting darker.

To be honest, he has not gotten used to the emptiness of Marikka's absence.

But little by little, his emotions were returning to normal.

"It's not that I've forgotten my sadness, but I'm forgetting my sadness, something like that.

I talk to myself without saying anything to anyone. Whether the line makes sense or not is of secondary importance.

Reiko says nothing, but just bows to Jin silently.

* * * * * * * * * * * *

"So, I borrow it for a year, and then I buy it after seeing your performance, is that right?"

At Miyagi, Ernst II was meeting with his ministers to decide what to do with the mining golem that Jin had offered.

As a result, it was decided to borrow the golem for a year first, and if its usefulness was confirmed, to buy it, otherwise to continue borrowing it or terminate the contract.

It was a fairly safe decision.

If this had been 400 years ago, when the female emperor was reigning, he would have purchased 20 of them immediately, but unfortunately, Jin has not had such a good track record.

On the other hand, there was no problem with the refining machines (magi-machines), and Ernst II's decision was upheld.

With this decision, the support from Jin was decided early the next day.
