Strongest Onmyouji's Isekai Adventure ~ The Monsters are too weak compared to my Youkai Servant's~

And the next day.

Me, Amu, Efa and Mabel, the four of them, were walking down the sewer aisle stretching underground in Rodney.

Even when it comes to sewers, this place is about as wide as a river with a mainstream waterway. The ceiling was also quite high as to whether it was prepared for water increase.

It's much wider spatially than the passages in the underground dungeons that got lost last year.

I look around and squeal what I think.

"You don't smell as bad as I thought."

"That's right."

The leading Amu answers.

"Unused water drips out of the tap all the time."

In Rodney, large quantities of water are being pulled from two nearby sources.

We don't store them in large ponds or anything, so the amount overflowing from the water supply yard is built to flow straight into the sewage.

The amount of water itself seems pretty good, so I guess the sewage flow isn't that dirty either.

"... well, that's why I don't want to stay long"

So is the place, but also in time. There's a distance to the target point, so if you're bringing too much, it's night.

In the end, the departure had been extended until after noon.

It took me a little while to convince Saisha that I was going to find the entrance.

He seemed to have a good track record in magic practice, but without the experience of rough things, he'd just be a foot wrapper. It would be helpful if you waited very long for me.

Ahead of Amu, we continue down the aisle by the waterway.

Following Amu is me and Efa. And the tail is Mabel.

The aisle is not that wide, so given the space to wield the weapon, there can only be one person in the avant-garde.

There's nothing wrong with that.

"Hey, hey, Amu"

Efa shouts anxiously as she looks sideways at the waterway.

"This, monsters come out of the river, they don't... right?

"Hmm, you don't know"

"Yeah, yeah..."

Away from the sewage flow as Efa feared and noticed.

Efa's anxiety is good.

Because of this, I'm arranging an avant-garde, but if I get accidentally fired laterally from the river, there's no formation or anything.

To the scared Efa, Amu laughs and says hehe.

"Just kidding. There's nothing wrong with a monster living in the sewage because it's like a slime of aquatic habitat at best."

"Oh yeah..."

"Sometimes fear comes back from the river that runs into you."

"Yep..."

"Hey, don't threaten me too much. It's okay, Efa."

I've been thinking about the possibility, so I'm taking action.

At that time, from the ceiling of the aisle, a slight wind-cut sound was heard.

Amu looks over his head first, and in the rear there are signs that Mabel will also be in shape.

It was - a big bat-shaped monster - that appeared in the light of the human rattle illuminating overhead.

But before the two girls took action, a human rattle was affixed to their noses.

Mark with one hand.

Yang's Phase - The Art of Thin Thunder

Bachi, sparks scattered with the sound, and the bat dropped into the waterway as it raised white smoke.

It's a lot less powerful than the original lightning, so maybe it's not dead... okay.

Says Amu as if he was half frightened.

"... aren't you reacting too fast?

"Really?

It's much easier to have an entity than a demon (yawn) that melts and ambushes in the dark.

Finally, I have been releasing "Thin Thunder" regularly into the waterway since earlier.

Even a somewhat powerful monster wouldn't have accumulated, so it shouldn't even take an unintentional hit out of the water.

After a while, two rats (rats) appeared in front of the aisle, as many as wolves.

Illuminated by human rattle lights and frightening your body for a moment, it strips its front teeth against us.

Teeth that reflected light were blunt.

It's definitely a rat-shaped monster with iron teeth.

"You're finally out."

Amu putting up his sword with laughter.

Two human rattles fly from behind it and stick it to Felik Rat's head.

Even then the spark flew with the bursting sound, and the two monsters turned upside down and cramped.

There is a burning smell of body hair.

Amu looks back at me and says dissatisfied.

"Hey, these things are usually handled by the avant-garde,"

"I could take you down, okay?"

I just want to get it done and go home.

"Hmm."

Amu walked over to Felik Rat's carcass dissatisfied and both kicked into the sewage.

"That, you don't collect the material? They say metal teeth sell for a good price."

"It's nothing, it's not a big deal. You want to go home soon anyway."

……

I couldn't say anything to Amu like a shank. [M]

Oh... I think I'm in a bad mood.

With that in mind, I fly the human rattle to the wind-cut sound I heard overhead again.

But before the human rattle was pasted, a sword shot from behind stabbed through the assaulting bat-shaped monster.

The sword strikes softly as it pierces the monster, drawing parabolas and falling to the far water.

I looked back and said with a little shuddering.

"Mabel. You can't collect your swords here, so I wish you'd let your enemies at a distance"

"Fine. Me too, I want to be useful"

That's what Mabel said with her motivated eyes.

Um, what happened to this kid suddenly, too?

****

"Ah."

After a while again, Amu accidentally raised his voice and rushed over to the wall of the aisle.

I'm leaning in like I found something.

"What's up?

"Pickup"

It was the Imperial silver coin that pinched me with my fingers and showed me.

It's hard to think that someone dropped it here... so maybe when the water increased due to rain or something, it caught something overflowing from the waterway.

"Heh. You were right about the hardware dropping in the sewer."

"Hmm..."

Amu walks out again with an uncleaned reply.

"I knew it was weird."

"Change?

"Here, a little too pretty for a sewer"

"Yeah, Ko, is this beautiful...?

Efa says as she looks at the wall where a little something creeps up.

"I'm not. Somehow, it's too clean."

Amu continues as he walks.

"Sewer passages are usually more messy. Garbage, metal chips, that's what I'm talking about. But there's hardly anything like that here. The adventurer wasn't supposed to dive in a while."

"Hmm......"

"And"

Saying, Amu turned his wand sword forward and unleashed unchanging water magic.

Numerous ice columns poke at the forward Feliculat, letting it despair in an instant.

"In addition to bats, there are only iron rats and no slime at all. I think that's why it's so hoarded up like a hedron."

"Slime eats hedro?

"Come on. But don't you feel that way?

Well, I kind of get it.

I open my mouth a little bit.

"... Felik Rat, sure, but you ate it. From iron scraps to other monsters. It's that rat that's generating the mass, doesn't that mean it's eaten up garbage and slime?

"Mmm. There's a little less to mass occurrence..."

Amu says toothpick badly.

"Maybe solidify a lot somewhere..."

And, Amu suddenly cut the words and stopped his leg.

I also feel unspeakable signs and strengthen the human gutter lights.

It was the black furrows of the Feliculat that lit up the light.

Not one or two. The black fur fills the aisle far away.

That was just a huge crowd.

Countless eyes illuminated by light are directed at us.

I don't see the cowardice I had when I was one.

"Huh..."

The amu that caught my expression lags behind.

Well, this would just be a guard job.

A large crowd of rats are approaching us, led by a few brave ones.

To match it, when I tried to unleash the surgery - from the rear, an unexpected whimpering gust blew.

The wind blows luxuriously through the back of the aisle as it sweeps away a swarm of rats.

The bounced Felik rats fell into the waterway one after the other. Just electrically shocked by the lightning that was flowing in Thin Thunder, it drifts downstream as it floats puffy.

Even a few lucky enough to stay in the aisle showed no signs of movement, whether they were losing their mind or dead.

"... of now, Efa?

"Huh? That's right."

Answer as if Efa is nothing.

"Oh, you... you could have magical power so far?

"Eh heh, there were a lot of spirits in Astilia who went on summer vacation. And because of what Lise gave me."

……

To us who are silent, Efa says with her neck tilted.

"What's going on? Do you want to move on?
