Regret because you'll regret it later.

"Well, Jin, you can make it. ...... Oh, my God. I didn't know I was so close to the person I was looking for.

Reinhardt is downcast. No wonder.

Reinhardt can make a magic tool that simply releases magic power. However, if he does not use it, he will be depleted of magic power.

The best way to understand it is to liken it to diabetes caused by magic power.

If the magic power (sugar) is more than necessary, it is harmful to the body, and if it is depleted, it is not good for the body.

It is no wonder that they assumed that no one could make a magical tool that would stop at the right place.

However, thinking about it, even though we have only recently come to know the person's personality, it would not be normal to confide the secret of Elsa's body, the Viscount's daughter, to a stranger from nowhere. She is a relative of Elsa's, but she is also a daughter of another family. It is a common practice in the world to lose a recipient simply because she is ill.

"If Erza had been my sister instead of my cousin, I would have consulted with her long ago.

Reinhardt said to himself. It was too late now.

Just then there is another knock at the door. This time Anne opens the door.

"There you are, Reinhardt."

The knocker was Fritz.

"Of course you heard, Elsa is gone. Her nanny Meine is with her, and I will find out where they are. So, Reinhard, you can go now."

"What?"

Reinhardt doesn't quite understand what he's being told. It's unusual for him to be so quick-witted.

"In other words, you don't have to babysit Erza anymore. Thank you."

With that, Fritz turned on his heel and left without waiting for Reinhardt's reply. From the beginning to the end, Fritz did not even look at Jin.

"......"

"............"

Silence falls between the two. Then both let out a sigh,

"And so it goes. Jin, you will leave here tomorrow. Are you still interested in coming to my country?

Reinhardt asked Jin with a sad smile. Jin quickly responded.

Read at https://w w w . m t l r e a d e r.com

Yes, of course. So you will leave tomorrow morning, is that correct?　What are your plans for today?

Hearing this, Reinhardt now smiled happily.

"Oh, yes!　Thank you, Jin. I was worried that you might not like our country after all the trouble we've been through. I'll be out of town for formalities in the morning. I'll be back this afternoon."

"Okay. I'll just kill some time until the evening.

Jin responded to Reinhardt's explanation. The two men parted for the moment.

After having a proper breakfast at the hotel, Jin moved to Horai Island again.

Jin had an idea.

It was a magical tool to search for Erza's whereabouts. Assuming that Erza is wearing the dagger and the brooch made by Jin, they should have Jin's magic pattern engraved on them.

The protection ring is excluded because it would have become familiar with the owner's magic.

In other words, I decided to make a high-performance magic detector.

"Master (my lord), aren't we going to continue with the armor today?

Laozi asks. Jin nodded his head,

"Yes. I have an idea. Please prepare the materials.

"Yes, sir.

What Jin wanted to make was a higher level version of a magic detector, a magic tool, or rather, a magic device that detects an individual's magic power and locates his/her whereabouts.

To tell the truth, Reiko's predecessor, Automata, had been developing such a device for about 50 years in order to find a successor after the death of their predecessor.

However, after a thousand years of search, the device was destroyed without a trace after Jin's discovery, and some of the automata's knowledge has been lost, so it has not been possible to reproduce the device so far, No, there was not even a trace of such a magical device in the past. Including the memory.

Therefore, Jin also had to be made from scratch.

The basic device is a sensing device that is also installed in Reiko. It is attuned to a specific magical power and knows its strength and direction. The accuracy is not very good.

We are planning to install three large scale ones on Horai Island.

If the direction is known, a straight line can be drawn in each direction from two distant points, and the intersection point will indicate the location. Since the two points are immovable, Jin thought that if he increased the number of observation units to a total of three, he could expect considerable accuracy in case there was an object on the straight line connecting the two points.

As with radio waves, the tuning of magic is based on the principles of resonance and resonance. Instead of coils, they are made of magic crystals engraved with the magic formula. Jin carefully writes down the formula.

Beside him, Reiko was working on the housing and support legs of the detector under Jin's direction.

Lao Tzu, the brain of Horaijima, was watching the scene and wished he had arms and legs to be of more use to Jin.

Now, Jin was at a loss as to how to quantify the direction in which the magic power was detected. In the original world, there are azimuth magnets and the position of the North Star.

"Ah, we need a compass for ship and plane navigation, too.

So, Jin temporarily stops assembling the detector and tries to make a compass.

As an experiment, he magnetizes a steel needle, sticks it in a piece of paper, and floats it in a basin of water. He has a needle, paper, and a basin, but magnetizing them is difficult.

In the end, we transformed (formed) copper into copper wire and coated the surface with insulating paint made from the sap of a tree similar to poison oak.

An electromagnet can be made by connecting a battery made by alternately stacking copper and zinc sheets and inserting a cloth soaked in citran juice between the sheets to an enameled wire-like wire made in this way.

A steel needle was magnetized using an iron core, and finally a magnetic needle was completed.

When I put it in a piece of paper and float it in water, the simple compass points north and south. This shows that this planet also has a geomagnetic field.

Jin now proceeds to make a full-fledged compass. The needle is made of steel, the bearing is a small crystal, and the case is made of light silver. The compass is divided at 360 degrees, and 16 azimuths are marked: east, west, north, south, northeast, northwest, southeast, southwest, and 8 azimuths below northeast, which is in between.

For greater accuracy, a north star or other landmark should be used, but this is sufficient for a start.

The three detectors with built-in azimuth panels were completed in about three hours. Each of them has an independent golem brain and can exchange information with a manacam (a magical elemental communication device).

I placed each of them on the top of the laboratory in the south of Horai Island, on Tatsumi Bay in the southeast, and on the top of a small mountain in an orchard in the southwest.

"Okay, I've adjusted them to my magic power now. Let me know which direction you sense each of them."

Lao Tzu was in charge. Once the information is sent to Lao Tzu, Lao Tzu will process it and pass it on to Jin.

Read at https://w w w . m t l r e a d e r.com

"My Lord, the largest response is 179 for A, 347 for B, and 61 for C, C is 61.

A is for the laboratory, B is for Tatsumi Bay, and C is for the orchard. The magnetic north is 0, and the values are expressed in 360 degree clockwise direction.

Yes, I am right in front of the institute. This should work. Can you find other Golems?

Read at https://w w w . m t l r e a d e r.com

The golems Jin created all have the same magic pattern as Jin's. The only difference is their strength. The difference is strength. So we can use the same detector to find them.

"The golems on the island are too numerous to identify."

That's what it means. If they were right in front of us, there would be many ways to identify them, but it seems that the magic pattern alone is not enough.

"Oh, I see. What about the flying squadron?"

There are only a few golems flying around for mapping purposes.

"Yes, that would be possible. The location is ......."

But Jin interrupted him,

"Oh, I don't need a detailed report. But please make sure that you can report not only numerically but also in terms of points on the finished map.

Lao Tzu tells him to do so. It is not easy to understand if you report the direction in numerical values.

"Yes, sir.

Now, Horai Island can search for the members below Jin.

If they wanted to, they could search for Erza as well. Or more precisely, Erza's magic tools.

Read at https://w w w . m t l r e a d e r.com

"Master, I have a favor to ask you."

Lao Tzu, having decided that there was a break in the search, tells Jin about the wish that he had just thought of.

"Could you please build me an external humanoid terminal?

Read at https://w w w . m t l r e a d e r.com

In other words, a golem or an automata that Lao Tzu can control.

"Then I can help my master (my lord) more.

Jin thought about it. The idea was to have Reiko and Lao Tzu monitor each other and deal with runaway situations, but he wondered if such a terminal for Lao Tzu would reduce Reiko's advantage.

"You don't have to be as strong as Reiko, at most you can be as strong as Ann."

Seeing Jin's hesitation, Lao Tzu added. Jin gave his permission, saying that would be fine.

"Okay. Do you have any hope for the appearance?

Read at https://w w w . m t l r e a d e r.com

"Yes, I want it to look like an old man, as befits the name of Lao Tzu.

Indeed, there is no golem with the appearance of an old man in Horai Island now.

"Okay. Leave it to me.

So Jin immediately decided to make a special automata for Laozi.

The basic structure is the same as Ann's. The only difference is that it is male. The difference is that it is male-oriented and does not have a control core, which is equivalent to a brain.

Instead, it is equipped with a mana telecam and a remote-controlled magi device, and is controlled by Lao Tzu.

Therefore, the maximum output is equivalent to 20 percent of Reiko's power.

I thought for a moment about making it look like a hermit because it is Lao-tzu, but in the end I decided to make it look like a butler. It is a combination of Elsa's butler, Adberg, and Reinhardt's butler, Claude, divided by two.

Between you and me, I decided to go with the hermit look simply because it would be too dignified and would make Jin feel self-conscious.

The following is an example of the "Hermit" style.

One of the targets is acting alone.

All right, get him.

Copy that.

Copy that.

Jin returned to Ikasanat from Horai Island in the late afternoon.

With night still to come, Jin walks around the town looking for armor, looking for stores that sell weapons and armor. But he doesn't find much. In the first place, full-body armor like that worn by a knight is custom-made.

"I'll talk to Reinhardt about it later.

Giving up, Jin returns to the hotel.
