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

Restart your steps, for a moment (* thirty minutes) or so.

The sewer was plugged into a point that drew a loose curve.

"Seika."

I can speak to Mabel from behind.

"How much longer until there's a ring?

"Um, it's supposed to be..."

And I stopped.

"Amu, wait"

"What?"

"Another herd."

Amu glances over and looks at the end of the aisle.

"... where?

"I can't see it from here. A little bit further around the corner, there's a place like a room. Looks like there's a lot of them out there."

"How do you know that?"

"Kind of."

From the end of the aisle, a small bat returns.

When the bat returned to its human gutter state, it remained invisible and dissolved into the scenery.

Even in complete darkness, bats work vision.

Those are inaudible to people, because they look around with high sounds.

"Apparently it hasn't come out in the aisle. I think it's okay to get a little closer."

I will take the lead and proceed with caution.

Eventually, I could see the room and the bumpy place.

In such a way that the passageway walls are gone, there is space.

I'm sure that was the space to leave the materials at the time of construction.

However, the entrance was wide open as if it had been swallowed by something.

Perhaps the interior of the room should also be quite spacious.

Otherwise - you can't even feel the frightening signs so far.

Even though there was still a distance from the room, countless small signs, such as slight vibrations that transmitted the ground and the sound of something clamoring, were clearly felt even here.

They behind you, too. You see, there's a tense vibe.

I sighed unexpectedly.

I don't know...

"Wow, I'll do it?

Efa says what she wants, but I shake my head to the side.

"No, now I'll do it."

It would be troublesome if there was a leak.

Let's make sure we get there.

Carefully approach the entrance to the room.

And I stamped him quietly.

"The Phase of the Soil - The Art of Perforation"

A number of quartz columns erupted, blocking the entrance to the room like a cage.

Even if Felik Rat, who noticed the anomaly, arrives, naturally he can't leave.

All right, all right.

When I joined the Amu in such a way as to surround them, I flew a single human rattle and slid it from between the pillars into the room.

Well, will you die from this?

"The Phase of Saturday, Friday and Water - The Art of Poisonous Phosphorus Mist"

Shoo, steam erupts from the human rattle with momentum.

Then the rats inside rumbled out like they had gone mad.

Flipping and cramping one after the other with the screaming of a tall severed demon.

Eventually, the sewer became quiet.

After a little time, I will skip the de-cursing human rattle and quench the pillars of Transmission and Poison Phosphorus Mist.

"What have you just done...?

I answer confused amu.

"I let you breathe the poisonous air."

When phosphorus (phosphorus) is reacted with water from a strong base (alkaline), it produces a colorless, smelly and virulent gas.

A beast of that magnitude is a substitute for death without sucking a large amount.

"What's poisonous air... like gushing in a mine?

"You know very well. It's something else."

As I say, I step inside to check on the room.

Felikulat's remains are illuminated by the lights of the human rattle. It was a huge number. I'm sure this place was like a nest.

Further back, fly the human rattle.

and then.

The lights suddenly swallowed by something that emerged from the darkness.

Floating in the light for a moment were blunt glowing fangs and nose surfaces.

I will not fly the human rattle again, but pull Amu and Efa, who were nearby, immediately to the wall.

The next moment, a black shadow burst through the darkness.

The shadow passes through our space until now. He flies out of the room, crosses the waterway as he bubbles up, and clashes against the opposite wall.

The impact causes paralysis and dust to fall from the ceiling.

"Hey, what, that!

Mabel, who was watching the aisle outside the room, shouted surprised.

I fly the human rattle of the lights, and observe the shadows - the monsters of the newcomers.

He looked like a tall rat.

It seems to have elongated tails, tight hands and feet, and rounded ears.

However, should its length be about two and a half lengths (* about seven or five meters)? I could say it was huge. It was big.

Furthermore, its body has no hairs and is instead covered in layered metal leather like sheet metal applied together. Looks tough to see.

I twist my neck.

"Um, what did I say about that?

"A, it's Adamantraat! I can't believe you're going out to a place like this!

Amu raises his voice in amazement.

Yes, he was. He was. It's like Felix Rat's best balls.

Hmm, if I had been there, I would have breathed the "Poison Phosphorus Mist"... but I wonder if that was simply not enough. Sometimes that poison air is lighter than air, so if you lay your head down and stand still, you can't make them breathe lethal amounts.

Adamantrat pulls his head out of the wall and slowly turns back this way.

Unexpectedly, his crushed eyes are a little cute, but he seemed clearly furious with us, the intruders.

Efa, don't move from the wall.

"Uh, eh?

As I walked out into the center of the room, I leaned on myself and gently flashed the lights.

The black eye of a giant rat turns this way.

Again, the ramp started.

"Mm."

"Oh, my God!

When Mabel and Amu make a mistake, they tap into the battle axe and wand sword, respectively.

But they were played softly with a hard metal sound.

Uh, you look pretty tough after all.

"Seika!

Amu looks back and screams at me, who was in the direction of the advance.

That metal giant is about to bounce me off. I switched my position with the ceremony I was at the wall.

The rampant giant rat storms the wall behind the room with excessive momentum as it blows the replaced human rat under wind pressure.

"Ha, you're more of a pig than a rat"

Well, that body won't help with small turns or anything, and I guess it's a reasonable way of attacking.

And so I turn my face to the girl with the axe.

"And Mabel. Amu will be pulled out to you anyway."

"... the weapon is too light"

Mabel said something strange.

The battle axe I have now is big enough, but a lot smaller than that one I had in the semifinals.

No way. I can't swing that stuff in the sewer, so I don't have a choice.

Adamantraat wanders.

Two avant-garde girls rushed in like they panicked and jumped out in front of me.

"Seika, stay back."

"Oh, you're the rear guard!? Why are you provoking me with light!?

"Uh, but hey."

The opponent's attacks are dominated by advances, and I don't feel much more meaningful to the formation than the avant-garde is normally pulled out.

Besides, it would have been a hassle if I hadn't caught my attention and had gone to Efa.

Well... I guess they're also trying to serve as avant-gardes.

Shall I let you two have flowers here?

I fly a few human rattles.

They were applied to various parts of the metal leather of the giant rat that was looking back.

Mark.

The Golden Phase - The Art of Gold Eating Mercury

A silver liquid stained from the human rattle twitches through the metal leather.

Adamantrat, whose body was low for a ramp, accidentally opened its eyes.

"Giggy - - Huh!!

A giant rat rolls around the floor of the room messed up.

Apparently he was trying to strip off the sticky human rattle.

That's surprising. Does that metal skin also have any sensation?

Eventually, a human rattle torn by friction, lost its power and fell to the floor.

An angry giant rat peels out his teeth and stares at me.

"Oh, I can kill him now."

"Ha?

Three-degree advances are initiated.

Amu set up his sword and screamed like a jerk.

"Oh yeah, I'll do it!

Hilariously, Amu's wand sword swung to the right forelimb of the giant rat.

The flash that was played earlier.

But now - a blade of misrils crushed the metal leather like a candy worker and cut off its legs.

"Ngi!!

I lose my leg, which was supposed to kick the ground, so Adamantrat can relax and roll on the floor.

He wakes up a giant with his remaining legs and looks back at us with his rough breath.

On its head - Mabel's battle axe swung down momentum.

It sounds like a boulder has fallen, and the whole sewer shakes.

Adamantrat's head was completely blown apart.

Pull the battle axe out of the sludge of blood, brains and metal pieces, and Mabel, covered in return blood, bears it on her shoulders.

"Hmm."

He exhaled satisfactorily and then tilted his neck.

"Something was softening, I feel"

And he looks back at me and asks me.

"Seika did it?

"Oh, yes, I am."

"How? I thought I saw something like silver water."

"Erm... there are metals like mercury that make other metals brittle"

The metal discovered by an alchemist in the Kingdom of Frank, Gallia's Mercury (Gallium), has the property of blurring it out when it touches another metal.

If you use surgery to erode it efficiently, it is possible to make it brittle even in a short amount of time.

"You've heard similar conversations before."

Amu, who was coming nearby, said as if he was frightened.

Then, when he suddenly looks like one of the bad guys, he starts talking blurry somehow.

"And the... I'm sorry"

"Hmm?"

"... To be honest, I think the outlook was sweet. No swarm of iron rats, no Adamantrat could have done anything without you or Efa."

"Don't worry about it. It's the guard's job to burn it down with magical firepower."

"Yeah. Usually, the avant-garde is something that draws proper attention and becomes a wall. If the guards weren't you guys, it wouldn't have been weird if the party had collapsed... After all, I shouldn't have made it easy for you to dive into the sewer. I was in a little too much shape. I'm sorry."

To Amu, who drops his shoulders, I think a little, then smile and say.

"Hmm, right. But if you're able to reflect on it yourself, that's enough. I'm alive now, no matter what. I hope this failure helps next."

"Yeah......"

"Even I broke the formation from myself. Now that I think about it, I might as well have gotten Amu and Mabel to draw their attention and stood around trying not to push them forward"

"Mmm..."

"Both adventurer circumstances and monster extermination are the most familiar with Amu. Promise, remember? I'm counting on you the next time I go on a more decent adventure."

"!... ha"

The usual reply.

I add, smiling lightly.

"More than that, you reflect on the stumbling blocks in the kitchen. Smiley and Fuyumar said so. You are so..."

I reached out to Amu's head... so I noticed and pulled my hand in.

I almost did it...

Amu, leaning his head, turns to me when he sees me pull my hand in.

"... why are you stopping doing this?"

"What?

"It's nothing!

Say it like Amu got mad.

"I mean, what's a stuffing? I didn't do that!

"What..."

I accidentally opened my eyes and lost my words.

"Me... did you say that?

"I told you! And... what did you say? S, Mille? Students from what province? Was there someone like that?

"No... nothing"

I held my mouth by my hand and turned away from Amu, who seemed surprised.

... that's just what's wrong.

I can't believe you confuse the memories of a previous life with memories far older than reincarnating them, too.

I've lived too long, but is that the harm?

- Yes, master.

No... no.

It's just that Amu's behavior earlier overlapped so badly with that kid that I felt weird.

Yeah, that kid did it too, and he was one depressed when he failed to get on track.

Maybe there is an untrained?

To fail to keep an eye on that child until the end, just like his disciples did until then.

"Seika-kun! Over here, over here!"

I look back as a voice.

When I saw it, Efa, with the white lights of the Spirit of Light, was inviting me in the back of the room.

"... what's up?

I'm heading there early so I can mislead something.

Scattering the human rattle of the lights as we walked, we found that the room was bigger than we thought.

Apparently, the rats were spreading the walls of the original room considerably.

In the deepest, slightly deeper part of the room that Efa points to... there was some massive pile of crap.

Crap, like chains or nails or parts of armor, most of it looks like metal chips.

"Feliklat collected it, huh? But why..."

"Uh, probably bait."

Said Amu, who was following me from behind.

"Iron rats and adamant rats also eat metal, but they don't seem to need that much. So this is how you save for a nest when you don't eat at once."

"Heh..."

Looks like an ant.

Speaking of which, further south of Egypt, I had heard that there were hairless rats digging nests in the ground and living in groups like ants.

Perhaps the massive outbreak of Felik Rat was also due to the fact that Adamantrat, his best friend, got lost from somewhere and was able to create a community with him as its culmination.

"Seika."

And Mabel follows me around my waist a little bit from behind.

"The ring. Maybe it's in there."

"... ah!

I totally forgot.

Then we all started to flip a pile of crap.

I just noticed after I started doing it...... a little less than half the amount.

Can you find this...?

A small silver ring reflected the light when the sheet metal was removed, thinking, etc.

"Whoa!"

Pick up that little ring.

I found it.

With that said, I didn't ask for details about the shape or anything, but I'm sure this must be it.

I raise my voice with a ring. [M]

"There it is!

"I want to find it!

"There it is!

"Probably this..."

Looking around, everyone had a ring in their hands that looked like it.

I say softly. [M]

"... no which one!

I guess I'll just have to contact the guild once and have all the crap brought out.
