Solo Dungeon Streamer-I Am Overpowered

Then, all five heads suddenly opened their mouths and shot beams of heat. I mean, you'd think a dragon that just jumped out of the water would shoot water, right? But no, it's heat rays for some reason.

'Water Dragon.'

As the five heat beams aimed to incinerate me, Tenko summoned a massive amount of water from the ocean above, shaping it into a gigantic dragon that swallowed both the beams and the dragon.

: Isn't Tenko-san way too strong?

: Yeah, her abilities are crazy, but she only works well in water environments, right?

: I don't think Kisaragi-kun would use a shikigami with such limited abilities.

: Is water really that limiting, though?

: Considering how few dungeons have water, it's pretty restricted.

The dragon, completely enveloped by Tenko's water magic, probably wouldn't take much damage since it was originally swimming in the ocean. But if I freeze the water, that could be a different story. Instead of summoning a shikigami that controls ice, I decided to use ice magic myself to freeze Tenko's water dragon solid.

The dragon, now encased in ice, was quickly targeted by Sagojo, who unleashed some kind of strange water wave from his trident.

"What's that?"

: Wait, you don't know?

: Kisaragi-kun, seriously…

: At least know all your shikigami's abilities, smh.

: Another unknown ability from your own shikigami, lol.

Well, I can't help it if I don't know. Still, whatever that water wave from Sagojo's trident was, it had the power to shatter the massive block of ice that contained the dragon. It looked like nothing more than a wave of water, but somehow it turned into an incredible force. I'm really curious about how that works.

'...No chance to shine.'

Kichijin, who hadn't really done anything in the fight, sulked while picking up the magic stone that had fallen. Well, Kichijin is versatile, but not as specialized in certain areas as other shikigami.

"So, the water's all gone and the sea floor is just... left here?"

: Pretty much, yeah.

: What about it?

: Isn't this a gold mine for rare metals?

: Is it really that easy?

I had the same thought. Up until now, I'd ignored the possibility of finding rare metals because I didn't know how to extract them, and it was too dark to see anything anyway. But now that it's so clearly visible, it feels wrong to leave it behind.

: But the lower levels might have the same layout.

: Why not check them out first?

: You can gather rare metals on your way back.

: Dungeon exploration should take priority over the rare metals, right?

: Just do what you want, Kisaragi-kun.

: Yeah, go with what feels right.

"Yeah, you're probably right about leaving it for the way back."

I decided to summon Kasha now to carry all the magic stones we'd collected along the way. I felt a bit weird about summoning Kasha while we were underwater earlier, but now that it's getting heavy, I need the help.

The one thing that would really annoy me now is if the next floor was flooded again. Just when I thought I was done with water, having to go back into it would be a pain. Once humans experience comfort, it's hard to let go of it—kind of like how you can bear summer heat without air conditioning until you've used it, and then you can't stand even 30-degree weather without turning it on.

As I approached the stairs to the 61st floor, there was another door, so I opened it cautiously. Peeking down, it didn't look like there was any water. Maybe the floors below aren't submerged?

"Alright, let's head down."

: Looking forward to seeing the deep floors of Nagoya Dungeon.

: If there's no water, anyone can explore it!

: Yeah, except for the journey down to the 60th floor, lol.

: Kisaragi-kun, make sure to drain the water from floors 11 to 59 for us.

: How exactly is he supposed to do that?

: Just drain it like it's leftover bathwater or something, lol.

When I finished descending the stairs, there was another door at the bottom. A little annoyed, I pushed open the heavy steel door… and soft, moonlit light poured in.

"…There's seriously an ancient city down here."

: That's so cool.

: The atmosphere is full of mystery.

: So wait, is this dungeon some ancient civilization's relic that just surfaced a few decades ago?

: Stop spouting random conspiracy theories in the comment section.

: If you've got crazy ideas, post them on social media, lol.

Can I really call it an ancient city? Walking along a stone-paved path lined with columns, I could see ruins of what were clearly once buildings, and in the distance, there was a massive stone castle-like structure. Also, this 61st floor is absurdly large.

"It might be faster to survey this from above."

Looking up, I saw what looked like a moon hovering over the water's surface. So the ocean is floating above again... What is with this dungeon? Unlike the 60th floor, though, there are clearly many man-made structures here, with huge stone pillars rising from the water.

Using magic, I created footholds in the air, ascending higher like I was climbing stairs. From up here, I could see the vastness of the 61st floor.

: Isn't this way too big?

: Yeah, it's insanely large.

: Totally gives off ancient ruins vibes.

: There's something incredibly romantic about submerged ancient ruins.

: The idea of a dungeon filled with submerged ruins isn't just an archaeological discovery—it's world-changing.

I'm no historian, so I have no idea how old these ruins are or how much they might be worth. Still, I can't help but feel excited at the thought of exploring these ancient remnants.

"Hm?"

As I was climbing the transparent steps and surveying the area, my phone suddenly rang. The caller ID said it was Ryuusuke Aizawa.

"Hello?"

'Hey… I just got a report from the Union that your stream has become quite a big deal. Just to double-check, where exactly are you right now?'

"I'm on the 61st floor of the Nagoya Dungeon."

He let out a deep, exhausted sigh.

'I'm not saying you need to come back to the surface right now, but could you collect some of the stone materials from that ruin you're exploring? Even just some loose pieces would do.'

"Sure. I'll also take some pictures of the area."

: It's hilarious how we can hear the whole conversation.

: The Union's not the only one going crazy—social media and the Dungeon Association are in an uproar too, lol.

: I bet historians and researchers studying dungeons are probably losing their minds over this.

: I'm in a dungeon history class at college, and let me tell you, the professors were already losing it when they saw the footage from the Shibuya Dungeon's deep floors.

: Lol.

: Those professors are probably long gone by now.
