The will-o’-the-wisps, which floated lightly, attacked in large quantities.
「I’ve got it!」
Elena took a step forward and began to cast magic.
Together with a『Ju!』sound, the rain that Elena created using Water Magic got rid of the wil-o’-the-wisps in succession.
And then, the wil-o’-the-wisps run about trying to escape.
However, the rain, which Elena created, doesn’t have the power like the last time I’ve seen it.
I thought she’s going easy on them, but it seems to be different.
Perhaps, when the weather system magic is used outside the dungeon, the power will increase.
But still, water seemed to be the weakness of the wil-o’-the-wisps, most of them that blocked our way had disappeared. The few wil-o’-the-wisps that survived were repelled using Aya and Hilda’s fire-engine’s hosing-down-like water attack.
I, too, sliced several of them that attacked from right behind us into two with the White Belt Sword and we gained a complete shutout victory.
「Onii-chan, they were weaker than some in the lower floors.」
「Well, all of us can use Water Magic
and due to us joining together, it will be such a thing.」
Other than such a thing,
the White Belt Sword’s『Fire attributed monster subjugation』trial had been cleared with 10/10 during the fight just now. The remaining trials were Wind and Earth with 5 each.
Well, let’s do the trials slowly.
Afterwards, we were able to find the stairs towards the seventeenth floor without difficulty.
***
When we went to the seventeenth floor, the sea of clouds spread out again.
However, the area is dark this time.
The atmosphere seems to be similar to the moment when the sun sets.
When I checked the current time using my smartphone, it’s still morning.
It’s probably this floor’s special phenomenon.
When we advance through the dark……
「Ah! Thunderhead!」
The Thunderhead that appeared three floors below–in the fourteenth floor–appeared again.
However, its appearance seems to be different from the fourteenth floor’s Thunderhead.
「This Thunderhead is black, isn’t it?」
At first, I thought that the area is dark, but it’s different after all.
The fourteenth floor’s Thunderhead was white,
the Thunderhead here was black like a rain cloud.
When I used【Appraisal】, it seems to be called『Dark Thunderhead』.
What a simple name.
When we wait and see,
the Thunderheads slowly began to gather around us.
And then, we had been encircled by the Dark Thunderhead.
「Onii-chan, it’s dark.」
The Dark Thunderheads that surrounded us blocked the light, making the area even darker.
And then, finally, it became pitch dark.
「I will light a fire.」
Thanks to Hilda lighting a fire using magic, we’re somehow able to see,
but because of the Dark Thunderhead, we can’t see anything at all from about 20 m ahead.
Then, a Predicted Attack Area aimed at Hilda suddenly appeared,
I promptly wedge myself in between and erected a barrier.
*Gakin.*
Something like black tentacles stretched out from the Dark Thunderheads crowding around the vicinity.
Black tentacles……
Uhg, it’s an unpleasant trauma……
We’ll get nowhere as it is.
「Hilda. Since I will take charge of the light, take charge of the offensive.」
「Yes.」
I lit up the area with Incandescent Light Bulb Magic
while Hilda began attacking the surrounding Dark Thunderhead.
Like the Thunderhead, fire seemed to be the weakness of the Dark Thunderhead; a hole opened in the encirclement.
After that, while Elena and I were defending, Hilda was attacking at the same time
and we somehow managed to annihilate the Dark Thunderheads.
N? What was Aya doing, you ask?
She wasn’t able to use【Downburst】with the Dark Thunderheads blocking above,
