Three days later, Thor and seven others, ready to go, headed for the abandoned underground prison.

The flying dragon boat has a capacity of five passengers, but since adult males are the standard, the number of passengers can be increased a little if there are many women and children on board.

"Really, are you sure you're okay in such light clothes?"

That's all I need. I'd take off more if I had to.

"I didn't bring a tent or a sleeping bag.

"Yes, don't worry. We've got plenty to replace it.

"What? Kee-chan, don't you have a pom pom bed?"

I told you I don't want it. You idiot."

What the children call by its cute name is a folding bunk that can be deployed to fit the steps of a staircase.

It was a favorite of Moo's because it bounced well, but it was heavy in its own way because of the steel framework.

It seems that the reduction of the luggage also helped to carry a larger number of people.

After landing safely on the ground in front of the fort, the group greets the familiar adventurers and heads toward the center of the swamp.

The muddy paths had become much easier to walk on, thanks to the efforts of the silver class, including Sorrugum and others, as well as the steady supply of corruption-resistant redwood from the neighboring town of Bossalia.

Using the key of the white skull on the first basement floor, we went down the stairs to the sixth floor.

After exiting through the white door, we headed for the rusty blue door right next to it.

Kikiriri shivers slightly in the chilly air of the second floor, and glances at his companions' outfits.

She then speaks enviously.

"That's nice. You missed something."

Thor and his team's equipment had been redesigned as they ventured deeper into the depths.

However, the increase was mainly limited to items related to the black vajra stone.

Thor's appearance was greatly changed.

He is covered with red dragon scale armor, which was finally completed.

On the shoulder of his right arm, which holds a sword, a large red jade is attached, on the other side an azure jade, and in the center of his chest a black hard jade, as if protecting his heart, each of which emits a dazzling light.

The workmanship is so natural that it looks as if it had been embedded there from the beginning, and no sign of any workmanship can be seen at all by the untrained eye.

The previous silver snakeskin armor had been flashy in its own way, but the new armor stood out even more, thanks in part to the eye-catching jewels.

But it suits Thor's imposing appearance.

On his back was his familiar blue snakeskin cloak.

The sword at his waist is still a single-edged blade made of silver, as he is still short of iron.

Of course, the spare sword machete with the fangs of a rotting dragon is still in place.

Sora wears only a loose robe woven of breathable marsh spider silk, without a breastplate.

On her chest is a necklace of azure jade, which prevents her condition from changing, and a blue ribbon that holds up her hair, a combination of soothing colors.

The black vajra ring that adorned her white finger was unique in one respect.

Like the girl, Yuril also wears a robe made of spider silk, but this robe is of a sleek design that makes it easy to see the silhouette of her body.

Her braided silver hair was beautifully adorned with a crown of azure jewelry, and a necklace of gray crystalline stones swayed around her bosom with a subdued glow.

Furthermore, a prominent black jewel was attached to the cuirass of her right hand, which was clasped only by the middle finger, adding a vivid accent.

Finally, Mu is covered in white beast fur, but his feet are covered with purple-striped thunderbolts, and his golden curls are adorned with a small crown and his favorites.

Around his neck, a black vajra stone necklace in the shape of a beetle and a small leather drawstring are swinging.

With a good mood on his face, the child proudly wears a spinning halo of light.

"Let's go, then!"

Kikiriri pulls out a small blue skull from the glove compartment that lines the leather belt crossed around his ample waist.

She pushes it into the hollow and pulls it like a handle, and the thick door creaks open.

Sora and Mu peek through the door and roll their eyes in surprise at the unexpected sight.

The place unexpectedly looked like a natural cave.

The reddish rock surface of the sides and ceiling were exposed.

The floor is only dented and protruding, and is far from being a staircase.

However, although there is a certain degree of incline, the passage is wide and it does not seem to be too difficult to proceed.

The group began to descend silently into the caverns that lead to the depths of the earth.

Yuril and Mu almost fell down several times due to the smooth texture of the floor and walls, but they managed to walk through ten floors in less than an hour.

When a dead-end door came into view, the alert Sora let out a bouncy cry.

"Wow, what is that? That sounds like fun."

It was a group of cloths hung across the ceiling of the rather narrow passageway.

The ends of the bundles of cloth were tied tightly to hooks stuck into the rock wall.

The wall was not an artificial wall made of piled up square stones, so there must have been no restraint.

They were apparently hanging bedding.

Moo jumped up and started spinning around in front of the comfortable-looking bed.

"Come on, To-chan, come on! Come on! Put Moo on!"

"Calm down, there."

The child was lifted up and placed on the suspended bedding, and immediately began to laugh out loud while swaying his body from side to side.

If you look closely, you can see a small ladder propped up against the wall, which appears to be used to climb up and down.

There are also hooks attached to the rock wall below the ladder, on which the child's luggage can be hooked.

"Sola, you can leave the magic stone lamp here, too.

"Is that so?"

"Yes, it will just get in the way down the road."

With these words, Kikiriri inserted a blue skull into the door at the end of the hall, and opened it at once.

At the same time, heat and a dull light leaked out from behind it.

Behind the door was a desolate landscape of bare reddish-brown rocks.
