"Phew..."

Four of us will lead Mr. Sister down the aisle by the waterway.

The tunnel, made of stone sets, was very dark and full of damp, lukewarm air.

Besides, the smell of getting up from the sewage is quite strong.

The effect of Sanctère prevents nausea and toxins, but it's still a rather harsh environment.

"Exactly..."

Stop, Mr. Sister, and soak up the sweat floating on your forehead.

The breath is rough and looks terribly tired.

After entering the underground waterway, will it be about half a day?

Though we occasionally take a break, it's about time we get fatigued.

Though small things like bats and mice, there have already been several battles with demons.

"Are you all right? You don't look so good."

"Hey, I'm getting tired..."

"From here on out, let me lead the way. Lend me a lamp and a map."

That's what I said, Mr. Nino, who keeps his stuff from Mr. Sister.

That should be called a B-rank adventurer?

Despite her even smaller and more luxurious physique than Mr. Sister's, she could afford her face.

But I can just draw attention to letting all the girls have their luggage.

"Me too, shall we have a little?

"Fine. I'm working out."

"No, but..."

"You must devote all your energy to maintaining the sanctuary. Because my temper is getting stronger and stronger."

Oh man, you don't even have an island to mount...

But you're right about what you're saying.

As the underground waterway progresses, the concentration of qi is increasing, albeit slightly.

Maintaining the sanctuary is a lifeline, although not an immediate level of bodily harm.

"Should I go somewhere with red marks on it?

"Yes, that's said to be the deepest part of the underground waterway. It's just a long way from here, so it'd be nice to camp along the way."

"It's about time it got dark out there."

Take out your pocket watch and crush it, Mr. Rowga.

About thirty minutes to walk further from here.

Suddenly the passage widened and the sight opened at once.

Apparently, this is where the sewage from all over town meets.

We can't help but breathe in a spacious space like an underground lake.

"It's huge!

"That's just fine. Let's just say we rest here today."

"Yes! Me, it's time for my legs to be at the limit..."

"Mm...! There's something here, be careful!

I felt a slight but strange sign around me.

This is not like a mouse or a bat.

When I urge everyone to be vigilant, I immediately pull out my sword and take my stand.

"Damn!"

"Shit, it's coming from below!

Suddenly five ghouls jumped out of the sewage.

It looks like he hid himself under the water until we got down the street.

Damn, do something nasty!

When I cut Ghoul's head off, I immediately kicked him in.

Clean hit.

Gould, who gets an intense shot in the belly, falls into the sewage out of balance as it is.

"Ooh!!

Along with the roar, Mr. Rowga's shield bash burst.

Of the remaining ghouls, three are blown together.

Oh, wow, power!

Beshari and Ghoul, slammed against the wall, fell straight into the sewage and stopped moving.

Then Mr. Nino cuts off Ghoul's neck, which was left with a weapon like a black dagger.

"Look......! Gentlemen, were you hurt?

"Oh, thanks to Sieg, we're safe. Thanks for the warning."

"... let's thank you once and for all. I didn't expect you to realize it sooner than I did."

Don't bluff, Mr. Nino, but keep your head down gently.

When it comes to sneaking, were you indeed an Eastern warrior specializing in covert operations?

I've heard the name, but you've never seen the real thing before.

My hair is black, and maybe Mr. Nino has Oriental blood.

"It's no big deal about this. Signal detection is fundamental."

"Really? I find it quite difficult to feel the enemy out of sight."

"Higher technology, I think."

Nino says it out in a clear tone.

That, is it?

A swordsman can fight even with his eyes closed, my sister said.

"But... that's a little weird"

"Hmm?"

"When I work for the church, I often crusade the undead...... I've never been ambushed before."

Mr. Sister tilted his neck as he watched the fallen gools.

Keep it up. She roars to think as she presses her hand against her chin.

"A race called Ghoul is basically extremely low in intelligence. You may say you don't. Basically speaking of what they do, just walk around there and prey on what you see. We can't afford to ambush our prey and attack it all at once."

"I see. That certainly bothers me."

"From what I've seen, it looks like the other ghouls......?

Mr. Nino crouches on the spot and peeks into Ghoul's face.

Then the surface of the sewage behind it rippled.

- Loose.

Huge black shadows appear on cloudy underwater.

"Dangerous!!

"Heh!?

I pushed Mr. Nino's body backwards.

At about the same time, the water cracks and a giant skeleton shows up.

Dude, how come there's something like this in the underground waterway...?

Corners twisting and pounding heaven, fangs tearing flesh and crushing bones, nails crushing rocks as well.

This monster...

"Dragon Zombie......!!

The four of us shouted the name in unison.
