It was a very different kind of heat than the fourth floor that awaited the crack gap between the levels of the dungeon and the cherry blossoms passing through a harsh path that could not be called a road.

"Nh....! What is this... it's like a thick fog..."

The space ahead of the crack was filled with hot fog like hot water, and it was difficult to even see a few steps ahead.

Fog, moya, haze.

The cherry blossoms quickly understood the identity of the white smoke, which seemed neither.

"... hot water (...), this is..."

"Exactly."

The magic general Suzuri advanced in front of the cherry blossoms without changing his voice tone in an attitude that seemed to feel the heat and dust.

"The water that has fallen from the second tier travels through the third tier and eventually undergoes the burning heat of the fourth tier at the bottom, turning it into steam and hot water. It's an environment that doesn't attract organisms in a different sense than the fourth hierarchy."

"Hah, hah... so to speak..."

Melissa, who managed to follow her to the third floor, managed to squeeze out her fine voice as she seemed to be stuck in the environment of exhaustion and steam baths.

Without heat-resistant equipment with a cooling function, it is not strange that it has collapsed long ago.

"There is a hypothesis that each hierarchy in the Elemental Ark symbolizes the four main elements… the first level of soil, the second level of water, and the fourth level of fire. And the third floor is wind or air....."

"Was it a mistake between steam and hot air?"

\26779; (Nai) gazed at the surroundings and sandwiched his mouth.

Humidity, heat, heated lukewarm feet and cherry blossoms make this place feel like a lump of uncomfortable elements.

You might even say that the fourth level is still more comfortable without a gentle humidity.

"Melissa, do something about the water for now. If you keep your sights blocked, you're not going to be scouting."

"Uhh, yeah... if you blow it with the magic of the wind..."

"Keep it to a minimum. If we get rid of the extensive steam, they won't be able to steal it."

Melissa was cautiously creating a wind dome centered on herself, stretching her face with tension, after receiving advice that she could not ignore even from a tin.

"This much...?

"It's acceptable. Travel to high ground for now. From there, you'll be able to see the whole third level."

While removing the water that blocks the view by the magic of the wind, the movement resumes towards the tip of the rock that protrudes beyond the Cloud Sea.

In the meantime, the cherry blossoms constantly gazed at the surroundings and kept throwing the questions that had come to mind.

"The steam is deep above my head and I can't see the ceiling well... the light-emitting function seems to be working... but I'm worried that the light is weak anyway. Are you sure you lived in such an environment? Were there any ancient survivors?

"These environments are the lowest of the third tier. Both humans and demons lived in higher places. There must be a base in Agart Lam."

"... so there's no rough watch here, but if the hot air clears over a wide area, you can see it from above. That crack must not have made sense."

Looking down at the bottom of the third hierarchy from the top of the same hierarchy, it looks like you are looking down at the clouds from the top of the mountain, and the scenery looks like a white sea.

Even though it is deep underground, if a similar scenery is reproduced at the top of the surface, it is likely that there is a structure that can name the hierarchy that symbolizes the attributes of the air.

"Hello... is Green Hollow Town's hot spring from here...?

"I don't know. Nothing but the third level is the destination of the water that spills out of the second level and the burning heat of the fourth level. They must have reached the formation around the dungeon."

"The Green Hollow spring may come from you."

The cherry blossoms began to talk about topics unrelated to the dungeon and Agat Lam, with a calm voice that suppressed anger and sadness as they walked along the slimy slopes.

"Speaking of which, my father liked hot springs too. There were a lot of volcanoes in my hometown, and there were hot springs all over the mountain."

"... it's a waste of time."

"How about you, Magic General? Have you been influenced by your father?

There is no response from the tin.

However, the cherry blossoms did not try to repeat the same topic as they were satisfied with the mere fact that they were able to put it into words.

The cherry blossoms eventually reach their immediate destination - the tip of the rock that protrudes from the sea of steam.

The view from there was just covered in white smoke, and I couldn't even see the outline of the building.

"What do you mean? Nothing."

Look up.

The cherry blossoms that irritate the cherry blossoms are short and ruthless.

The cherry blossoms looked up at the ceiling, as they were told, and kept their mouths open.

Melissa, who raised her gaze late, couldn't even raise her voice with dismay, and couldn't even stand still.

"Ba... stupid..."

At last the cherry blossoms squeeze out their words.

"The island (...) floats (...), (...), (...), (...),"

Apart from calling it a "floating island", there was no room for expression.

A floating island, like a giant key through the ground, floats naturally in the air on a third level higher than any previous level.

And not one or two.

More than a dozen islands were stationary in the air with some distance just by sight, dropping several dark shadows into the steam cloud sea.

There are road-like artifacts between the islands, some of which stretch toward the ceiling, catch the water flowing from the second level, and circle the islands like rivers floating in space.

And the unreceived drifting water drifted like a waterfall, spraying white veils in the air and playing light, giving the floating archipelago a mysterious colour.

"Understood? This is the third level, an ark that stores the remnants of the ancient city. Either or all of them are the castles of Agart Lam... we should challenge."
