March 30th, Merce's birthday.

At 5:00 a.m. Celuloa time, Jin flew to Horai Island through the Warp Gate of the and mixed 7.5% copper with mithril silver to make 92.5 mithril silver. He mixed mithril silver with 7.5 percent copper to make 92.5 mithril silver.

Silver is a metal that does not cause allergies (not at all) and does not rust (does not oxidize easily).

However, pure silver is soft and tends to turn black <.

925 silver mixed with 7.5 percent copper is called and is said to be harder and less prone to darkening than pure silver.

Since the chemical properties of mithril silver are similar to those of silver, Jin mixed it with copper to make an alloy that is hard and does not darken easily.

He shapes it into a ring and engraves the <> on it.

The energy source for activation, the magi crystal, is small and thin, and embedded in the ring so that it cannot be seen from the outside.

Normally, such < would be set in a rather conspicuous manner, but in order to make this ring <, they are embedded and not visible from the outside.

The same applies to the Magi Formula.

A thin layer of mithril silver is pasted on top of the engraved surface (since it is not a <>, the magick formula is maintained), and this is also made invisible from the outside.

Therefore, it looks like a simple ring of mithril silver.

Incidentally, it is for the middle finger of the right hand. The size was measured by Reiko with her amazing eyesight and spatial grasp.

(It is a gift from a man to a woman, but since it is from Jin, the patriarch of the family, to an underage family member, there is no problem.)

"This will do."

The ring was placed in a ready-made ring case and wrapped.

"Father, you might want to add a gerbera flower."

"Oh, that would be nice too."

There is also a flower garden on Horai Island, albeit on a smaller scale.

It is for emergency bouquets (the old man thoughtfully created it because Jin sometimes makes a fool of himself).

Topaz 1, a five-colored golem maid, is in charge of the garden, which is filled with roses and other flowers that bloom throughout the year.

"Gerbera is the birth flower of March, so..."

"Is that so? ......"

Here in Ars, too, there is a language of flowers and birth flowers according to the earth.

Jin fantasized about the possibility that there might have been transplants or reincarnations with such knowledge in the past. ......

* * * *

Jin then returns to .

Because of the time difference, it is still midnight in Leuthart.

The time difference between Esia, the capital of the Kingdom of Selroa, and Leusat, the capital of the Shoro Kingdom, is about 1 hour and 40 minutes, so if he goes to Leusat at 8:00 a.m., it would be 9:40 a.m. in Esia, if he calculates backward. If we go to Leusert at 8:00 a.m., Esire will be at 9:40 a.m.

(I should pretend to go to the bathroom in the <> and go to Leuthart. ......)

Thinking of this, Jin left the <> and returned to the castle in the wind as if he had taken a walk in the courtyard.

"Oh, Mr. Jin, are you taking a walk? Jin-san, are you going for a walk?"

"Ah, Rorona-san. Yes, I woke up a little early.

I'll put it that way...

"Uh, yes."

Lorona is acting as if she is somehow aware of the situation.

Although she is not a member of the Jin family, she knows more than enough about Jin's abilities.

We went straight to the cafeteria, where we met the three members of the <>, Arnold, Delfina, and the others.

They all seemed to be on their way to eat.

It seems that they chose to eat together in the cafeteria rather than get room service.

By the way, Chelle and the five-colored golem maids are also following us. Not to mention Reiko.

Hope is the only one who is doing maintenance and checks on the as we are going to use it today.

"You like the seasoning here, Arnold?"

"Yes, I do. This country is like a successor to the old Dinaric Kingdom, so I like the flavors that seem to have been passed down from one generation to the next.

This morning's menu consisted of freshly baked bread, sausage, plain omelet, crispy bacon, boiled eggs, aged cheese, vegetable and fruit salad. Hot milk or mixed fruit juice.

"This aged cheese must be made in the mountainous region."

This cheese is from the eastern part of the Kingdom of Cerroa, a region called Ribas.

It is similar to Camembert cheese in modern Japan.

Bacon is also called roast bacon, which is smoked for a long time to give it a unique aroma.

Sausages, classified as wiener sausages in modern Japan, are small and bite-sized, but when you bite into one, the juices overflow.

The bread is made with grape yeast. Some of them are made into grape bread and have a unique flavor.

It was a little heavy for Jin's breakfast, but he ate it all.

And Lorona and the three members of the ate up all of the food without leaving any leftovers.

The time was 8:00 a.m..

The time was 8:00 a.m.

As agreed yesterday, we split up into Jin's and Makina's for a soil survey.

< are Lorona from , Yoh Nouki from , and Arnold and Chelle. Marcel, the king's brother, will also be on board.

will be joined by Kik Masukawa and Laktato of the , and Delfina. The Minister of Agriculture and Forestry, Mr. Bowanni, will be on board.

< are loaded on each of them. Not to mention protective equipment.

Shall we go then?

Yes, sir.

<

The points to be surveyed have been discussed.

The number of concentric circles from the center is 2 for the center or , 8 for the surrounding , and 18 for the surrounding .

This number is based on the of an atom.

Jin and Makina take half of the electron shells. In short, there are 1, 4, and 9 positions.

* * * * * *

The measurement time, including preparation, is 10 to 20 minutes.

Travel time is 15 to 20 minutes.

We estimate that it will take about 8 to 9 hours to survey 14 sites.

Jin moved to Leuthart as scheduled to use the restroom.

At this time, he was replaced by a by the consideration of the old man.

About two hours later, the doppelganger will switch places with Jin, this time in the bathroom.

In the meantime, => hides himself in the control room and avoids contact with others as much as possible.

This is not to reveal his true identity, but to minimize the amount of information to be conveyed to the returning Jin.

Thanks to his arrangement, Jin was able to celebrate Mertze's birthday in good time.
