"...... Your Excellency, can I have about 10 grams of adamantite?"
Jin, who had been working on the tier, turned and made his request to Duke Breu.
"Duke, please. The royal family will pay for it."
Ernest XVII also offered his assistance. Adamantite is expensive even in this day and age.
Compared to light silver, which was used by Jin to make the magic tools for refining 400 years ago, adamantite is produced in smaller quantities and is more difficult to refine, so that the market price is around 70 The market price of adamantite is about 70,000 dollars per gram. In other words, each gram is worth 70,000 yen.
Ten grams of adamantite was worth 700,000 yen, and Ernest XVII told him that the royal family would pay for it.
"No, Your Highness, don't worry about it. It is not every day that we have the opportunity to see the work of a magical engineer, the MagiCraft Meister, and the structure of an automata, which can be called an ancient artifact.
Duke Breu also seemed to have an extraordinary interest in magical engineering.
After receiving the 10 grams of adamantite, Jin said
"<>"
He plated the sliding parts of the joints.
Adamantite has a specific gravity of 19.3.10 grams, which is not even the tip of a little finger.
However, it is one of the hardest metals in the world (the hardest being molecularly compressed hyperadamantite).
As usual, Jin plated it on the sliding parts of the joints to reduce rattling and wear at the same time.
The skeleton was made of nickel steel, which is resistant to wear, but this makes it even more durable.
"The magic nerve wires will be fine with the repair."
Mithril silver is resistant to oxidation. And since it was hermetically sealed, the deterioration was slight. However, the metal had become brittle due to fatigue at the points where it had been bent many times, and Jin had repaired them.
"The control core is also okay. The important magi devices are perfectly fine.
This is the proof that Jin did his job properly 400 years ago. Jin was happy, if I may say so myself.
"The magical muscle is still a little damaged. ......
This can't be helped.
Even if biological materials are excellent, 400 years is a long time.
The concentration of free magic element (ether) as high as that in the Kingdom of Egelea is not suitable for preservation of ecological materials, and magical muscles are consumable parts.
In addition, Tia's magical muscle is made of sandworm leather. It cannot be compared to the ancient dragon leather used for Reiko.
"...... what should I do?"
Jin thinks for a moment.
In Horai Island, we can use all the precious materials we want. Even the leather made from the shells of ...... ancient dragons. Of course, we must not overexploit.
Of course, he did not overhunt. It is because Jin does not like it.
Rather, they are actively protecting them, and the total number of confirmed ancient dragons now stands at 30. The number has increased by 1.2 times from 25 dragons in the previous survey conducted 300 years ago.
At the same time, the number of frost dragons, which prefer the shells of ancient dragons, has also increased from 220 to 240. I wonder what kind of protection they have given them.
What kind of protection has been done was to reduce the mortality rate of juveniles.
Specifically, some environmental improvements were made.
Even the ancient ancient dragons, which stand at the top of all life forms in Ars, are helpless in their larvae.
They are oviparous, but they lay their eggs in spring and hatch in autumn.
The efforts of Guth and other researchers have revealed that the key to winter survival is how much the larvae can grow before the cold weather arrives.
Since the diet of the larvae was also found to be freshwater fish, the old man farmed and increased the number of freshwater fish caught at the northern limit to improve the food situation.
I'll leave you with a short digression.
As expected, we cannot use shells of ancient dragons, but we can use threads of <>, which is the standard in Horai Island.
Nowadays, they are cultivated outside of Horai Island, and above all, it is an important industry of the Nordic Federation.
Jin refuses the Duke's request and takes two bundles of Grand Spider threads from the materials rack in the workshop, and transforms them into muscle tissue.
First, the fibers are twisted together to make them thicker, and at the same time, the ends are < together to make them look like muscles. The process took 15 seconds. This is the skill of a skilled craftsman who has worked on thousands of Golem automata.
Jin made 100 pairs of them in all. He started working on four pairs at a time, so the work was completed in about 10 minutes.
The Duke of Breu and King Ernest XVII, who were watching, were frozen with their mouths open. Even Rhodes seemed to be speechless.
The 100 pairs of muscles are attached to the designated points on the skeleton and wired with magical nerve wires.
Incidentally, it is said that there are more than 600 kinds of human muscles. The human body has over 600 types of muscles, and only 100 pairs of them are needed.
The functions are classified and shared, and also shared to reduce the overall number and to facilitate control.
However, the <> is not lost. This is the superior point of the Adriana style.
As a side note, Reiko has about 300 muscles, while the golems of Horai Island have about 200. This makes it possible for them to move in a more human-like manner.
"There we go. The skin is still fine.
In order to strengthen and improve the durability, the magical muscles and the magical skin are <.
Finally, the control core and other magickal devices are fine-tuned to the new muscles, and the process is complete.
"Tia, how are you feeling?"
Jin asked Tia after she had been dressed and reactivated.
"Yes, Jin-sama. "Yes, Master Jin. Thank you very much."
"Yes, I'm glad."
Jin then reported to Ernest XVII.
"Your Highness, the maintenance of the tier you requested has been completed without delay. ...... Your Highness?"
"...... ha! Thank you. Thank you, Master Jin. My sister will be pleased. Thank you!
Ernest XVII, who had been stunned, regained his composure at the sound of Jin's voice and hurried to reply.
Thanks to you, Your Highness, I have been able to have my body repaired. I would like to continue to serve you, Your Highness.
Tia bowed her head and thanked Ernest XVII for his hospitality.
"Yes, no, I'm glad."
By then, the Duke of Bruu was back on his feet,
"Thank you for your excellent performance, Mr. Jin!
He was in a good mood.
* * * *
Jin and the others returned to the parlor.
Ernest XVII started talking about how to thank Jin.
"Tia told me that the best way to thank the Magecraft Meister is not with gold, but with materials. Is that so?"
"......Yes, that's true. I would be especially happy if it were a rare material."
"Hmm."
Ernest XVII thought for a moment and opened his mouth again.
"The materials that can be found in our Egelea Kingdom are not that rare. ...... Yes,<> How about 10 standard pieces?"
Elradorite is the name of the mineral on the Laurentian continent, and its official name is <>. Its mineral name is .
Originally a mineral that does not exist on Arus, it was brought here in the form of a meteorite in the past, and has been dug up and utilized.
The names "mithianite" and "univasium" are derived from it.
No, I'm afraid it's not that valuable. How about 100 kilograms of light silver?
"Is such a small amount acceptable?"
In the past, the price of light silver (titanium in this world) was high, but since Jin made magic tools for refining 400 years ago, the unit price has continued to fall, and now it costs 20 The price of titanium was high in this world.
The time required for maintenance was less than one hour. Since the materials for the repair came from the Duke of Breu's workshop, he calculated that he would be able to get 20,000 yen for the pure labor.
"Yes, light silver has many uses."
"I see. If that's all right with you, Jin-dono, I'll do it. Duke ......, may I borrow it temporarily?"
Ernest XVII said that he would pay Jin the light silver that belonged to Duke Breu and make up the difference later.
In the end, Jin received 200 (...) kilograms of light silver as a reward.
