My guess was correct.

　Erithlonium, second, third, and fourth floors underground.
　I descended the dungeon, which was structured with a stream running through the islands and a bridge connecting them, almost in a bare minimum of time.

　If I was unarmed and without the will to attack, the monsters didn't attack me at all.

　The monsters are the same as those on the basement floor, all of them looking like fluffy fluff floating in the air.
　However, each level has a different color.

　I'm sure the effects are different, but I'm pretty sure that if you get hit by a self-destruct, "something goes down".
　That's just a hunch, but in this case it was a near-certain hunch.

　I'll come back later to confirm and collect the information if necessary.
　With that in mind, I went down to the fifth basement floor.

"Wow, this is intense again.

　I mumbled aloud, and the scene unfolded in front of me to the point of wrinkling my brow.

　First of all, it was snowing.
　Red snow - dungeon snow.
　It was embodied in magical power, and it was falling incessantly from the sky.

　In addition to the familiar scene, the color of the river was also red.
　Not just red, but a sludgy, "heavy" and "hot" red.

　Blood.

　A river of blood.
　Those words came to my mind first.

　It was an idyllic scene from the first to the fifth floor, but from the sixth floor onwards, it turned into a horrific hellscape.

　I stepped into such a bloody pond of hell, and I was unconsciously upset, almost resisting, and unconsciously put my hands on my hips in search of something to hang on to.

...... Ah, so that's what it's all about.

　It's a good thing I threw all my weapons out of the way.

　A thing to squirm with.
　To me now, it's a series of weapons, including two pistols.
　It was normal behavior for me to be pressurized by the sight in front of me and put my hands on the weapons for self-defense.

　Fluffy fluff passed in front of me.
　If I'd had a weapon, I would have reacted now, and I would have self-destructed.
　Follow the monster with the terrain, that's how it works.

　And even though it was a horrific hellish scene, the nature of the monster hadn't changed.
　They didn't react to me when I wasn't in an attack position.

　I started to walk away.
　I crossed island after island by bridge, scowling at the river of blood.

　Six floors below ground, seven floors, eight floors, nine floors, ten floors - all of them.

　When he began to feel nauseated in the blood pool hell that was growing heavier and hotter, the environment changed completely again.

　The eleventh floor, this time it was magma.

'In a way it's easier this way.

　I mumbled, chuckling.
　The basic structure is the same.

　There are islands, bridges to connect them, and fluff flying around.

　The magma is just hot, unlike the top, which is mentally crappy.
　Feeling a whole lot better, I moved on.

　I went down to the twelfth floor.

"Huh?

　I winced again.
　First to fifth floor, sixth to tenth floor.

　I thought the magma would continue until the fifteenth floor, since each one was the same, but I was suddenly betrayed.

　The twelfth floor of the Erislonium.
　This time it was empty.

　A very strange sight.
　Islands floating in the sky, with bridges over them.
　The bottom is invisible at the bottom, a strange look like the sky.

　On one of the islands in the distance, you can clearly see a staircase leading downward.

'It's a strange place,'

　I tweet and go further.
　I don't have a fear of heights, and I feel like I don't have a fear of heights anymore once I'm up here.
　Maybe it's the same feeling I get when I look down from the top of a building, but not when I look out of an airplane window.

　With that thought in mind, I crossed the islands and reached the stairs leading down.
　Going down there, I went back to Magma.

　It's the same configuration as the eleventh floor, Magma and the islands.

　I went down, wondering what it was all about.
　The thirteenth, fourteenth, and fifteenth floors...

　The fifteenth floor below Erislonium.
　There was no stairs leading down there when I came down.
　I crossed all the islands, circled around three times to be sure, and looked around from corner to corner.

　No, there are no stairs leading down.

　I mean.

"So this is the bottom floor.

　Now, what to do.
　To be honest, I'm a bit stumped.

　After all this time, I realize that I only know how to get to the genie's room.

　I only know of two ways to get to the genie's room.
　One is to be summoned by the spirits, the other is to go to the bottom floor and defeat the monster to enter.

　Strictly speaking, you can use the transfer room after the second time, but that's it.

　Those are the only two I know of, and I've come down to this point in Erislonium without the will to fight.

　Fluffy fluff floats around me.
　If I tried to fight and take them down, this would come at me all at once.

　Is it okay to fight in the first place?

　Considering what we've done so far, there's more than a good chance that Erislonium won't give us a path to the spirit room, no matter how many times we defeat it.
　No, it must be.

　何者かに殺され、あの手この手で人間を「拒絶」しているダンジョンになった。
　多分、いくらたおしても道は拓かれない。

「……」

　だったらどうする？
　その場に立ち止まって、あれこれ考えてみた。
　答えは出なかった。

　どうすればいいのかが分からない。

「みんなの意見を聞いてみるか」

　俺はそう思って、一旦脱出する事にした。
　そのままきた道を引き返していく。

　十五階、十四階、十三階、十二階――。

「むっ」

　マグマを抜けて、空島っぽい地下十二階に戻ってきた。

「そういえばここだけだな、この構造って」

　なんとなくその場で立ち止まった、腕組みして、上と下を交互に眺めて、考え込む。


　何の理由もなく、この階だけこうなってるとは思えない。
　この構造だと十人中十人が落ちないように立ち回る。

　そしてダンジョンに入れば十人中十人モンスターを倒すため戦闘モードに入る。

「……ということは」

　俺は上がってきたばかりの島の端っこにいった。
　橋ではなく、島の端っこ。
　そこから下をのぞき込む。

　どこまでも続く空。
　すくなくとも、見た目で言えば1万メートル以内に地面が見えないほどの高い空。

　ただの勘だ。
　しかし、確信に近い。

「……」

　俺は――そこから飛び降りた。

　体がぐんぐん加速して落ちていく。
　ぐるぐる回って、テレビで見たスカイダイビングのような動きに自然になっていく。

　おちて、おちて、落ち続けてーー十分。

　終わりはいきなりやってきた。
　まるで映画の場面転換の様に、いきなり目の前の景色が変わって、俺は、二本足で地面に立っていた。
　そこは何もない真っ白な空間。

　ダンジョンは奇妙な作りだったが。

「精霊の部屋は変わらないんだな」

　俺は目的地に辿り着いたと確信した。
