In this room, said Prince Gilbert, there is a door to the treasury.

It makes sense, since the palace is the residence of the royal family.

"The location is ......."

"Wait a minute!"

Jin stopped the king.

"Are you sure you want an outsider to hear such a thing?"

"Yes."

Gong Wang nodded seriously.

"You are an outsider, Jin-dono, but you don't belong to any country, do you?"

"Yes, well..."

That was what Jin himself had just said.

"Since you are such a Jin-dono, I would like you to attend the meeting.

"I understand."

This was proof of Jin's trust in him.

"So, the door is right under this bunk.

"What?"

If you move this bunk, the door will appear," said the king.

"I'll call the work golem for you now."

"...... No, that won't be necessary. Reiko, please."

"Yes, father."

Jin asked Reiko to move his bunk.

"Oh, that Miss Reiko is an automaton, isn't she? Then she's got a lot of power ......, eh?

Reiko took hold of the end of the bunk, lifted it easily, and moved it to the corner of the room. Of course, with the king in the bed.

She also secretly uses the force field generator, taking care not to damage the bunk.

The king and Nanaria, who had no idea that this was happening, were startled and their eyes were black and white.

Then they turned up the carpet on the floor after shifting the bunks, and sure enough, there was a door there.

"First of all, please open the door with this key.

The king handed Jin a silver key.

Jin inserted it into the keyhole on the floor and turned it, and the lock was released with a heavy <> sound.

The door on the floor lifted open.

Behind the door, there was a staircase leading to the basement.

"Go down about 30 steps and you will find a door. Here is the key to that door.

The king held out a golden key. But Jin did not take it.

"No, you must use it yourself.

"But I still can't walk well. ......"

But I can't walk well yet." Because he had been bedridden for a long time and had been suffering from a leg ailment, the muscles in his legs had not yet recovered.

"So please go with Nanaria."

"...... I understand."

Jin could not refuse the offer when he was told to do so by the king.

I will go first.

Reiko took the lead and went down the stairs. The staircase was about one meter wide. The light in the room was sufficient to see under her feet.

The keyhole in the door at the end of the stairs is also dimly visible.

Reiko gives her place to Nanaria.

"Your Majesty's representative, Nanaria-sama, please open the door.

Nanaria stepped forward with the key.

"......, then, I'll open it for you."

Nanaria inserts the golden key into the keyhole and turns it.

< and the lock opened.

From there, Reiko stands in front of the door again and opens it.

The door opens with a slight squeak, and behind it is a small, spacious room.

<> is attached to the ceiling, and the light turns on automatically.

(......?)

Jin felt that the strange feeling he had felt since he went down the stairs became stronger.

No, it is more correct to say "it felt right" rather than "it felt strange".

In other words,

（I mean that I felt that this place (...... was made by me or someone related to me in the past...).

(I wonder if this place was built by me, or someone related to me, in the past.

But this palace was built about 150 years ago, so it can't be the old Jin.

Then, it is natural to assume that he is related to Jin.

(......) Probably, <.

Jin guessed that one of the whom the old lord had dispatched to countries around the world to gather information when Horai Island was not yet exposed to the attacks of and , was in this country as an engineer. Jin guessed that one of the < sent by the old lord to countries around the world to gather information was here as a technician.

After clearing his mind, Jin took another look at the inside of the room.

The ceiling is almost entirely covered with <>. The luminous intensity per unit area is low, so it is not dazzling to look at.

(Maybe for cost reduction.) In general, <

In general, the brighter the <> is, the more expensive it is. For cost-effectiveness, it is cheaper to use a lot of dim ones.

Although Jin does not usually think about the cost, he knew that much as a common sense. ...... barely, though.

The walls are made of stone that has been treated with <. It looks like the same stone as in the palace. The floor is the same.

And, above all, there is a golem fixed to a built-in on the wall in front of the room.

It is directly in front of you when you enter the room, so you can't help but see it.

In fact, Nanaria could not take her eyes off the golem.

It is a male golem, about 1.8 meters tall, which is rather small for a golem.

Its color is deep blue. The exterior was probably made of light silver (= titanium), and the color was probably produced by adjusting the oxide film.

It has a simple outline with no unnecessary protrusions or accessories.

"May I take a closer look?

Jin asked, and Nanaria came back to herself,

"Oh, yes. Please take a look, Jin-sama.

She gave up her place.

"Well then."

Jin examines the golem with , and learns many things.

It is, of course, <.

The exterior is 64 light silver. The skeleton is the same. This composition is that of .

Looking at the overall structure, it is almost the same as that of Rand.

In other words, it was definitely a golem of Jin's lineage rather than that of .......

The maker is, as expected, <. Regulus 48, a.k.a. Garius.

The date of manufacture was 3761.

The overall performance is about one-third that of the Lando. But still, it was, and still is, the best golem in the world (excluding those related to Horai Island).

Let me explain the result to Nanaria, omitting the part related to Horai Island,

"It is wonderful!　!　It really existed!

She was overjoyed.

According to what I heard, there is an oral tradition in the Duke's family that <> is kept in a secret place.

The reason why Nanaria, who is not yet the queen, knows about it is that she is also of the royal family, albeit from a side line.

"Will she move?"

Nanaria asked Jin with a twinkle in her eyes.

Jin answered honestly that if Nanaria was related to the royal family, there was no need to hide anything.

"Of course I will move.

Jin told her honestly about this as well.
