The guy who told Hope to go to the .

"The zakkyo?"

"Yes. Look at that.

The man opened a door behind him.

There was ...... another door, and 100 meters underground, there was a large hall. Jin D and the others were in what looked like a waiting room.

"...... arena."

The center of the hall was one level lower, and there was a circular arena, perhaps 30 meters in diameter, surrounded by a high fence.

Surrounding the arena was a spectator's area, and about 500 people could be seen sitting in the audience seats.

There were some aristocrats, some merchants, some gangsters, and their companions and bodyguards.

The spectators seem to come and go by elevator, and those who use the stairs are those whom the gatekeeper deems <.

Hope was taken by one of the men.

Jin D. and Elsa D. are watching the situation. Reiko, too, is quiet for the moment.

She said to them,

"But you guys are so calm. Especially you, little girl, it's great that you don't cry.

"......"

Jin-D is at a loss for what to say.

But when he hears the following words, Jin-D is also enraged.

"Let the golems fight each other over there and make bets on who will win. And they're going to battle until one of them stops moving.

"What?"

Jin couldn't believe what he was hearing.

He was furious at those who would make the Golems break each other's bones just to make a bet, let alone a contest of skill.

"That's what I'm talking about. No one would bet on the golem you brought, but the customers are happy to see it destroyed.

One of the men guarding Jin-D and the others mocked.

"So that's why you're doing this.

That's what I meant.

* * * *

Jin D., now that he understood the situation, spent some time on Horai Island thinking.

"Escape is easy. But I want to help the investigators.

Jin thought that he would like to help the people on the side of the policemen as much as possible.

"What would you like to do, old man?"

"So that's how you're going to ingratiate yourself with the Franz kingdom."

<

The old man already had a peephole to see what was going on. But he can only <>, not make any moves.

And the move to do something was on the spot.

<>

* * * * * *

Ladies and gentlemen!

An announcer's voice echoed through the hall.

Before we begin our annual Golem battle, tonight we have a special entertainment!

The crowd cheers.

A battle between a squire golem, the pride of our underground arena, and the golem of a traveler's retinue!

Another cheer!

The outcome is too obvious to bet on, but enjoy the prelude over refreshments!

More cheers!

(They're all scum, aren't they?)

Jin D. was thinking about that,

(They're all scum, aren't they?) Jin D was thinking that, when he heard the following words: "......They're all peaceful people. What are these aristocrats here thinking?"

The female investigator also seemed to be thinking the same thing.

In the center of the arena stands Hope, and now another golem appears.

The cheers grow louder again.

The golem was a mid-tier battle golem that had won 10 consecutive victories in this dark arena.

Then, fight!

The battle golem kicks the floor.

* * * * * *

In Horai Island, both the view of Jin D and the image of the telescope operated by the old man are projected on the magic screen.

Jin D's view was as if seen with the naked eye, and the image from the <> was projected from a bird's eye view angle.

"So that's the middle man. ......"

Jin sighed.

<

"Right."

It was said to be a medium-sized company with 10 consecutive wins, but from Jin's point of view, it is .......

* * * *

""Oh ......!

Go!　Do it!　Smash it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!"

The crowd cheered, but not a single battle took place in the arena.

Or, more precisely, Hope is dodging all the attacks of the battle golem.

(It moves too slowly. ......)

The power is there, as one would expect. Or rather, most of its power is <.

If power is <, it is proportional to the weight and to the square of the velocity.

Since the velocity is not so great, the power comes from the weight.

In other words, it was the epitome of "if it hits, it is powerful, but if it doesn't hit, it is useless.

The difference in speed between Hope's speed and that of a combat golem is about 20 to 1.

In a one-on-one fight, Hope had no intention of losing.

""Don't you dare dawdle!""

Fight fair!

The crowd shouted, "Who the hell do you think you are?

（Well, it's time to fight back.)

Hope moves in behind the battle golem and throws a front kick at its back.

Hope weighs 75 kilograms and the Golem weighs about 300 kilograms. Roughly one to four.

The speed difference is 20 to 1.

Kinetic energy is proportional to weight and to the square of velocity.

In other words, Hope's kick is 100 times more powerful than that of the battle golem, simply calculated.

Hope's kick blasted the battle golem into the fence.
