"Tentatively, ......."

Elsa opened her mouth.

"Hmm?"

"If you were my brother Jin, what would you try?"

"What if it were me?　...... That is, without using bio-derived materials?"

"Yes."

"Yeah. ......"

Jin ponders for a moment. Erza kept her mouth shut so as not to disturb him, and thought about it herself.

"I wonder if it's a form drive.

"I think so, too.

Since the use of magic is a prerequisite, this is a reasonable conclusion.

"But, Brother Jin, there is one thing I'm wondering about."

What is it?

"About the <>. That's what Brother Jin named the method used to move the ...... enemy golem in the demon territory, is that right?

Yes, that's right.

"But my predecessor said that we should name it <> at the <> clan."

"Ah."

Yes, our predecessors had discovered the <> at the <> clan a thousand years ago.

"Indeed, that's what the records say. ......"

"But that may not be the same as the method that Brother Jin named <."

"I see. ......"

Although the first and the second generation have the same name < after 1000 years, it does not mean that the contents are the same. It does not mean that the contents are the same.

That is what Erza is saying.

"That's for sure. ......"

Jin thinks about it. The golem mining underground for resources is not what Jin calls <, but an extension of engineering magic <>.

It is maintenance free and will continue to move as long as there is free magic element (ether).

On the other hand, the <> named by Jin was a magic technology based on <> but specialized in movement.

"...... Oh, I see."

Jin suddenly understood.

"It is the same thing as the golem that is moving in the basement.

Probably because the previous generation had used it to create a golem for mining.

"The crystal golem that Stealina is using is also named by the previous generation, isn't it?"

And then?

What I named it is not the same as what my predecessors named it.

That makes sense.

Jin had a feeling of certainty that this was probably the closest to the truth.

"......, I understand."

Erza seemed to agree.

"But, Brother Jin. You didn't answer my first question.

"Yes, you did."

<

Jin thought again.

"......First, let's clarify the concept to organize it."

The name <> is decided to pay homage to the predecessors and call the method that drives the mining golem on Horai Island and the crystal golem in Stearena.

"Then what about the method used by <>?"

"...... hmm, <>... ......"

"Fluid transform drive?"

"Fluid deformable? I mean, it looks like it's not solid metal, but a virtual liquefied state, and then deformed, so I thought I'd call it that.

This was the beginning of Jin's interest in the fluid-form drive.

Hohod, a town in the south-central part of the Kingdom of Egelea.

It is a small town overlooking the Laajo Mine to the north and the Blue Lands to the east.

The town is reasonably prosperous because of its proximity to the mines, but it has yet to develop significantly.

This is because of Count Galana, who manages the mine area.

In a word, the people's lives are not enriched because of the heavy exploitation.

Therefore, the atmosphere of the town was quite rough, and there were many bad-tempered people, even criminals among them.

In such a situation, the security force dispatched by the Nostalgia Party began to patrol the town, and the security situation had improved considerably.

However, not all of the guards are members of the Nostalgia Party.

Because of the limited number of members, at least one of them was a member of the Nostalgia Party and the rest were hired workers.

Here in Hohod, the head of the guard is a member of the Nostalgia Party and six others are hired from other towns.

In addition, three general-purpose golems were dispatched for security.

"We received a call this morning. There have been a series of attacks on rogues in the towns of Midatona, Gidazo, and Lubu, seriously injuring some of them. The perpetrators are unknown. Please be careful."

This is what the head of the group told the members in an early morning meeting.

"Considering the location of the town, we think he is approaching us.

"Yes, sir."

The members of the team are all former soldiers or soldiers with some experience and are reasonably skilled. After the meeting, we were divided into groups of two, and went into town in pairs.

Three shifts a day, two in a team, with one guard golem. This was their style.

"If it was a ruffian who attacked us, we probably don't need to worry too much about it, do we?"

"I agree. But since we don't know what they were after, I guess they thought they couldn't be too careful.

The guards patrol the town, talking like this.

Morning, noon...... the town of Hohod was peaceful.

Then night came.

From 9 p.m. to 5 a.m. is the allotted time for the night duty.

I'm off then.

"Oh, go on."

The night passed as it always does at .......

Midnight, midnight. The moon......s southbound.

"Hmm?"

Two shadows stand blocking the guards at the entrance to town.

One of them is human, and the other is apparently a golem.

"...... what can I do for you?"

The two are wary, remembering what they heard in the morning meeting.

"We have no use for humans. I'm not here for humans. I'm here for your golem.

"What?　What do you mean?

The guard, unsure of the meaning, asks back, but the answer is unexpected.

"It means this. ......

Suddenly, the man's golem attacked him.

What? ......

Geef!

The golem hit the two guards, and then hit the guard's golem.

"What ...... are you ...... doing?"

Although they were hit, it did not seem to be with much force, and both seem to be OK.

However, the impact was considerable, and although they were clearly conscious, they were unable to stand up for a while, and could only watch the battle between the security golem and the mysterious golem.

Since two of the guards were harmed, the security golem recognized its opponent as hostile and intercepted it.

The mysterious golem was about 1.8 meters tall and was clad in heavy armor like that worn by soldiers.

In contrast, the security golem was 2 meters tall. Although it was a general-purpose golem, it was based on the golem of the Unified Party (Unifiler), so it had more than five times the power of a human being.

But...

"......What?

A startling scene unfolded.
