Dancing Circles on the Horizon of Events

Large hole drilled by Lucia's magic.

That's not the same as caves with decomposing surfaces or camouflage-shaped tunnels that are commonly found on the road......

From the front, it had a beautiful circular shape, it was a big hole.

It is a big hole like sharpened with a giant drill.

The inside of such a hole, because the surface was not reinforced......

It appeared that the brittle areas had fallen or were flooded with spring water.

If you went into the pit without any measures like this, it wouldn't be strange to be caught in a collapse whenever you could, I'd say.

Waltz, who saw it, went into an action.

On the surface of the tunnel, a gravity control system was used to form an outward 1G force field.

In other words, the wall of the tunnel itself attempts to fall (...) to the outside (...) side (...), thus preventing it from collapsing to the inside.

By the way.

As a result, one unusual phenomenon seemed to have occurred in the tunnel.

"Wow, wow! Standing on the wall doesn't fall, does it?! Sister!"

That's right.

Lucia was able to stand against gravity and against walls and ceilings, as Lucia said, standing vertically from the wall and raising her delightful voice.

"Well, that kind of magic on the wall... because you put something like that on it. By the way, can you even stand on the ceiling?

"Wow. True!"

"But when you jump or get out of the hole, it's out of effect, and you fall out of your head, so be careful, okay?

"What..."

and Lucia crouching in the ceiling with a surprised look on her face.

Seeing where her face was blue like that......

Maybe he was just about to jump right now.

Waltz and Lucia then continue to the back of the tunnel with similar interactions.

Retreat the rocks that were in the way of walking while Waltz ensured safety in the gravitational force field......

And Lucia uses fire magic to illuminate the area like a pine light, while exercising wind magic to ventilate...

Repeating such breathtaking work, the two advanced their legs to the point where there was a mineral vein of interest.

And when you come all the way to the cave penetration.

What came into their eyes was a wall stained with bright red on one side of the perimeter - a striped iron deposit.

This time it was an iron ore deposit that Waltz was staring at using an underground exploration radar.

Waltz scrapes it a little and takes it in his hand and starts to make sure of its ingredients.

Specifically, spectroscopy using invisible laser light.

As a result…

"Yeah. Definitely iron ore."

Waltz said so, shaking his neck vertically several times satisfactorily.

"I'm going to refine this and sell it to the merchants..."

"I don't care where you look from, it just looks like a bright red stone... (I wonder if I can sell it... this...)"

Looks like it's just a red rock.

As for Lucia, I couldn't believe it would turn into glossy iron.

But it's an unmistakable mass of iron ore.

It is a red iron mine that contained a lot of oxidized iron.

Or a chunk of rust, you might say.

Even in the modern world, the majority of iron products are made from red iron ore, and high-purity iron is produced using blast furnaces, converters, etc.

Perhaps the iron products in this world are also made using the same ore.

Nevertheless, that refining method should be door-to-door, as the history of the planet was.

"Even as it is, if you have the knowledge and technology on the buying side and you have a fair amount, you might be able to sell it... well, that would be difficult. So I'm going to turn this stone into shiny iron and sell it."

"Sister...... is that, maybe...... alchemy?

"Well...... right. Maybe you could say that."

and waltz mouthing such vague answers, remembering the history of the planet.

Then she gently floats only the arm of the manoeuvring armor that was transparent so Lucia wouldn't notice......

Protruding its fingertips into a rock made of iron ore deposits made of a material that is not comparable to diamonds and the like...

And she said this to Lucia, who had a strange look at the rock.

"Well, let's dig around, shall we?

It is that moment.

Dgowwwww!!

The rock, which was supposed to be hard, shredded, as if it were a frayed and collapsing brittle dirt wall.

Waltz began digging iron deposits by applying force to the arm of manoeuvring armor.

Look at that.

"Something... Wow..."

Lucia takes her breath inadvertently because of an incomprehensible phenomenon happening in front of her.

And she whines these words in that cave, where loud noises roar.

"Sister... you're unreasonable..." Boo.

"Hmm? Did I say something?

"Yeah. Nothing, huh?

That's all Lucia said, seems to have returned to observation again.

Then again, in front of their eyes, large quantities of iron ore will be mined as if they were to be shredded by giant heavy machinery….

And the shredded ore was carried out by the force field of Waltz's gravity control system, as if it were a belt conveyor.

Even such a sight seemed very interesting to Lucia......

She seemed to play with her fingertips sticking iron ore floating in the universe as she sparkled her eyes.
