- The 26th basement of the Imperial Labyrinth.

It was caved up ahead through the pit.

Except it's not a dark cave like Cave Field, which was on the upper level.

The high ceilings and the left and right walls about fifty meters away were pale and glowing.

Plus where we were standing was the main road about ten meters wide, and the left and right sides of the road were filled with water.

Road running through the middle of the river.

"Not Cave Field, but Undersea Cave Field."

"How did you build a place like this?

"That would be just like our sea field"

I got the materials I needed to build a variety of useful tools for my life.

The next thing people wanted was to enrich their diet.

Stand on the edge of the road and take a peek in the water.

Various fish swim freely around in the water, and shellfish can also be seen on the bottom of the water.

It's a place where you don't have a problem getting seafood.

"Then shouldn't we have built the ocean normally?

Sylvia's questions are good too.

"It may be hard to tell because I've come with a transfer, but near Imperial Capital - there is the sea where I traveled about two days by carriage. Empire shouldn't have that much trouble with seafood if you're careful how you travel and how you store it. Perhaps the search for a way to get seafood in a different environment than the sea has led to this kind of place."

"I see."

This is an interesting place to be now.

I don't have trouble with the lights to see if the walls themselves emit light.

Proceed through the submarine cave on the main road.

"Are you sure you don't have a problem going straight?

"Yes. The map says there's only been three divisions."

Let me get a map from Sylvia to confirm it.

There's a divide, but no problem.

Going down the road, it looks like it's splitting left and right, but even if we choose which one, we're starting to rendezvous at the end.

Don't worry about getting lost with this.

Instead of rushing through it all at once to see what the undersea cave field is like, proceed at a slow foothold.

- Pocha.

A big fish was coming out of the water on the left.

Look at me. I'm pounding my mouth.

"You're adorable"

"Really?

As opposed to me, Sylvia looks at the fish and smiles.

"No, that fish is like a demon"

"Huh..."

Melissa told me that she realized the fish was a demon, but it was already too late.

A water cannon fires from inside his mouth and hits his chest.

"I was there, I'm not..."

My coat got wet.

S-ranked gear that only looks like clothes but has a history.

There is no damage if you take a bullet of high density compressed water.

"Not at all... I can't believe you're attacking your husband."

The fish demons that attacked were skewered by Sylvia's thrown knife.

The knife had a wire attached to the patterned part so that it could be recovered even after throwing.

If we retrieve the knife, we can also retrieve the fish that was piercing us.

Fish demons have a look not so different from normal fish except that scales are harder than normal fish about a meter in size.

"I got it, but what are we gonna do with this guy?

"Let's cook when we get home"

Sackley, hold your breath. Store it in the storage ring.

I need to kill them at the very least because I can't keep them alive.

When it comes to cooking, I need to do it after I return because I am currently staying in an inn in Teito, but if I store it, the state of preservation will also be preserved, so it is not a problem.

"Again, if you check what's going on underwater, there are all kinds of creatures."

"That's true."

It doesn't look like there's the same kind of fish alone.

Peeping underwater, I had a big fish with orange eyes.

A big fish opened its mouth and attacked me.

"This looks delicious too"

A Sylvia knife I was peeking at with was piercing the fish.

"That's unforgiving."

"It's only an ingredient for me at the time of the attack."

"Oh, how about this stuff?

Reaching in the water, Melissa was peeling off the octopus that was snagged on the rock.

Holding him with both arms as he was, the octopus had grown up without the appearance of escaping although he was moving his legs.

"Tsubaka."

"It's small compared to Giant Kraken, but it looks delicious."

"Comparing size to that giant demon is wrong in itself..."

It is incorrect to compare the size with a demon such that it is more than thirty meters long.

If such a huge demon were in the labyrinth, that would be the only way the labyrinth would collapse.

"You wouldn't have trouble eating if you were this big."

The bamboo was held in Melissa's arms.

It was big enough.

Touch it with the tungtung.

"Sounds like a regular bamboo."

"Are ordinary fish and demonic fish living together here?

"It's rare, but it could also be a feature of the labyrinth"

Usually demons are stronger.

Because of this, demons survive better in the wild, where weak and strong eating is fundamental.

Symbiosis is difficult.

Therefore, it is rare that there are demons in the water with calm onions like this.

"This size would be cute, wouldn't it?"

"No, man, I knew I didn't get it"

They may be cute because of their small size, but I don't feel like I can hold them and laugh at them.

I can't do this forever.

"So..."

Let the catcher escape.

I can't help but take it home as an ingredient if it has been attacked and defeated, but I didn't come here to collect the ingredients, so I'll let the demons who haven't attacked me get away with it.

I give in to the water and let go of the octopus I was holding.

"Geez."

Suddenly Melissa fell into the water.

"What?"

I don't know what happened out of the blue.

But Sylvia watched closely.

"It's tough. Something like the tentacles of the octopus got tangled up in Melissa's leg and dragged her down into the water."

"Shit......!

Jump into the water.

At first it was only shallow enough to see the bottom, but at some point it was going to be nearly ten meters deep.

Melissa was...

On the bottom of the water was a bigger octopus than a man, entangling a tentacle stretched from the bottom of the water into Melissa's feet.

If you use magic, you can breathe in the water, and you can swim, but you can't swim on your own. Melissa is suddenly dragged into the water because of the rumbling, and you can't afford to use magic.

"Melissa, calm down"

I tell him to calm down in his reading, but he just slaps his tentacles with his cane.

It's a mindset that doesn't require a voice, so you can have an underwater conversation.

But he doesn't listen to me. I have no choice but to slash my tentacles and hold Melissa, who rambles, to the surface of the water.

Raise Melissa to the ground and let her breathe.

"So, it's okay!?

Silvia, who looks panicked, is rubbing Melissa's back to calm her down.

Let me sit down and take a break, too.

It's impossible to fight a demon while holding a rampant woman in the water.

There is no such thing as a large bamboo that was at the bottom of the water striking again.

We need to be vigilant because there may be other demons coming at us.

But it's hard to take Melissa, who can't swim in this undersea cave field. Nor do I know when I will be dragged underwater.

"Melissa, Ira"

"Yes?"

"What?"

I get a response from Ira, who was watching us.

"Alternate"

It's hard for Sylvia and I to explore.

You can't bring Illis in, you just have to bring Ira in.

Summon Ira.

"It's my turn from here."

"... Regards"

Return to the labyrinth even though depressed Melissa is not feeling better.

"Let's go!

In contrast, Ira, who is motivated to explore, takes the lead.
