"Ko, what is this...?"

Mr Liseau, who saw the sole, gives a surprise.

Leaving Bahamut, where we lived at the bottom, we returned to our original path and now headed downstream.

The reason for this is that this path, built beside the groundwater vein, is likely to continue all the way outside.

If there is such a way out, it is likely that many demons and chimeras have been unleashed on the outside world.

So we went downstream and continued to crusade the demons and chimeras we met.

And it's this end of the line that I found.

Even if it's just a dead end, it's just the end of the road we've been walking.

The water in the groundwater vein itself continued deeper from an empty hole in the wall.

And what surprised Mr. Liseau was the hole.

Technically, it's against the trail of destruction that supposedly forced the groundwater to crush and spread the flowing hole.

"Apparently, something forced the narrow underground aqueduct to go deep."

Mr. Ramies looks at the dilated hole and guesses what happened.

"Did you crush the rock and move on? Is that what Chimera can do?!?"

Mr. Liseau asks a question to Mr. Ganye, the biological parent of Chimera.

"Hmm, did you have that many gutsy chimeras in that demon-made chimera failure?

And, remembering the chimera made by the demon, Mr. Gun-ei leans his neck and thinks.

"... ah"

And raise your voice as if you remembered something.

If you say so, by the time I got here, there was no prototype chimera.

"" "" Prototype Chimera?

"Um, it's the final prototype chimera made by Nan to implant shards of white disaster. I'm pretty confident I just made the last one, or Ning Lo's greatest masterpiece. I just couldn't use the last remaining shard of white disaster, so I ended up just checking the performance of the body and dropping it in the disposal hole.

"" "" "Why did you flush such a dangerous thing? Ah!" "

Everyone's scratches echo at the bottom.

"No, it was so good, I didn't have to kill it myself."

"No, no, that would be crazy. I mean, it's not normal to throw away such a dangerous chimera!?"

When Mr. Roddy roughs up his voice, all the Lisaws with experience in fighting Chimera together nod yeah nagging.

"Hey Master Roddy, was the chimera strong enough that Master Roddy and the others fought?

and Mr. Almo, a fellow monk of Mr. Roddy's, asks.

"Hmm? Yeah, it was pretty strong. But what we fought for was a failure until we made our destiny."

"Failure?

Remembering the battle with the chimeras encountered in the courtyard and in the lab, Mr. Roddy nods in the face like he chewed up a bitter bug.

"Oh, I really thought the battle against the giant chimera we met, especially in that courtyard, would die"

"I can't believe Roddy said that much..."

Likewise, Mr. Chain, the wizard of Mr. Roddy's people, joins the interesting conversation.

He's a wizard, so he seems interested in the chimeras created by magic technology.

"The demons we encountered at the ruins referred to those chimeras failures, but they were quite strong. If we had been asked by Cyclone alone, we might have been wiped out before we ran into the finished chimera."

"... lying, that's it!?"

and Marcha, the swordsman, one of the last of Mr. Roddy's parties, is astonished.

That statement seemed shocking because they trusted Mr. Roddy wholeheartedly.

"Honestly, thanks to the boy, I was able to survive."

So Mr. Roddy looks at this one.

"That girl again..."

Mr. Almo stares at this one jeezy.

Those eyes are a complex, emotional gaze that doesn't seem angry.

You must be wondering if you really helped me.

"No, that was like a welcome to me from the rookie S-rank, and if Roddy and the others were really fighting, I wouldn't have made it."

"" "Right!!" "

Mr. Roddy's party members smile brightly at my words. [M]

I guess we all really trust Mr. Roddy.

"No, it's true I struggled..."

But Mr. Roddy takes the stance that I'm the only one who crusaded Chimera.

I was just pretending to struggle deliberately for the exam, and if I really fought, I would have won without struggling. I guess I wouldn't say that because I could have won the Chimera and the Demon on my own.

But I'd love to see Mr. Roddy and his real work someday.

I'm serious about s-rank adventurers who specialize in teamwork, so I'm sure it's awesome.

"But now you're untraceable..."

Whoa, there's been a lot of talk about Mr. Liseau and the others.

"Um, if you jump into this, you'll definitely die."

Huh? Die? Why? Why are you jumping in?

I think I would normally just have to dilate the hole for this.

Shall we give it a try?

"Tunnel extension!"

When I activate magic, I further widen the hole that the chimera forced me to widen, while reinforcing the ceiling and walls to further alter the hole expansion rate to create a path beside the groundwater vein where people can walk.

"Oh, my God, you can do this."

I was surprised that Mr. Lissoe and the others said they couldn't track him down, but I knew I could normally widen the hole.

"Then let's track down the escaped chimera."

……

And when I turned around, for some reason, everyone was looking at me round their eyes.

"What's wrong with you guys?

"" "." "Duh, what's going on? Then no!!" "" "

For some reason, everyone came in with their voices hammered.

What do you mean?

"Oh, my God!? What are you spreading the hole for?!? What's that magic?! Tell me!"

I love magic. Mr. Ramies stuffs me with excited eyes, but Mr. Foca and Mr. Roddy grab both arms and drag me from behind.

And Mr. Liseau came forward instead.

"Big man eating, is that... magic...?

"Yeah, mine magic to expand the cave."

"Mine magic!? But wouldn't it collapse if an amateur who's not even a miner puts a hole in a cave?

Oh, Mr. Lissoe and the others don't know about the miners' magic technology, do they?

That's why I didn't think I could keep track of it by widening the hole.

"It's okay. Mine magic won't collapse if you expand the cave. The amount of soil and rock spread out increases the density of the surrounding holes, so to the extent that it widens the holes slightly, the opposite is hard enough."

"Can magic even do that?"

"It's the same logic that makes it harder when you push soil and snow into the gutter. It's commonly used in collapsible geological mines."

"Really?

"Come on?"

Mr. Adventurers, did you know that? and check with each other.

Well, maybe it's magic that I haven't had a chance to find out that I don't know any mining people.

I was also told by a blacksmith I knew to look for good materials with my own eyes.

And I was going to spend a few months in the mine until I could appraise a good ore...

Yeah, let's forget about that time.

"... then let's go!

"Oh, oh..."

"Well, before that, learn more about the magical art of the day!!"

"Yes, yes, she's a good girl, so let's talk about that after work."

"No, it's a promise."

Um, it's something I'll teach you later.

"If you ask a wizard from a big mine there, you can tell me."

"All right, all right! You're a wizard dedicated to the mine!

Mr. Ramies doesn't brace after all.

A prototype of the most powerful chimera ever created to defeat the mysterious demons that have, nevertheless, crumbled ancient civilizations?

This is going to be a pretty rough opponent waiting.



Proceeding with mine magic expanding the hole, the wall ahead collapses with the sound of Bocco and a black hole appears.

"Looks like it's connected to a passage somewhere."

"Hmm, so maybe there's an escape chimera ahead of us. Everybody stay alert!

When Mr. Liseau orders vigilance, everyone sets up their weapons and goes into a state of war.

"Then we move on."

"Wait a minute, please"

But I will stop everyone who tries to move on.

"What's up, big guy?

"Magically investigate the spaces connected before that. Air diagnosis!"

A magical ball of blue light is emitted from the tip of your hand and you proceed to an empty hole in front.

Then the blue light turned from midway to purple, transforming into a bright red color at the next moment.

Yeah, I knew it.

"The colors have changed!?"

"Big man eating, what does that mean?

Mr. Liseau asks me, and I tell him what red light means.

"It shows that the air ahead is filled with poison."

"Poison!?"

Everyone on the spot turns up surprised and falls behind.

"What are you talking about, big guy eater?"

"There's a place in the mine that's filled with toxic poison air in the human body from time to time. This magic is magic to check out the air of those poisons. Blue is clean, purple is dangerous for a long stay, and red is life-threatening."

"Oh my God!?"

Mr. Liseau distorts his face in regret.

"Now let's move on..."

"So let's magically purify the air ahead and move on."

"... Huh?

What's Mr. Lissoe talking about? and look at me with a Kyotong face.

"Mine Magic Purifies the Poison Air Ahead"

"Can mine magic even do that!?"

"Yeah, magic developed to work safely in mines."

"Awesome Mine Magic"

"Is it possible that miners are awesome people?

The adventurers are having a conversation to change their perception of the miners.

"Well, it's rare to fight the powerful demons of ancient times who slept in the mines, so the miners also have the aspect of being a formidable warrior."

"Seriously!? Awesome miner!?"

"I'm sorry I thought I had to dig stones!

"Yay, I got caught up with an old miner the other day!? What do I do!

"Go apologize immediately!

"Whoa, I'm coming!

"After work, you idiots!

Oh, Mr. Lissoe scolded me.

"Anyway, if you can purify the air, can you ask for it, big guy?

"Yes, I'll take care of it"

Mr. Liseau asked me to activate the magic of air purification.

"Air Purifying!"

Once again unleashing magic into the space ahead, the balls of air diagnosis, which had been stained bright red until earlier, return to blue.

"Purification complete. Then let's go."

"Ah, oh.... Are you sure you're all right?

"Yeah, I'm fine."

Now that we're back on the move, we're going along the groundwater with the balls of air diagnosis ahead of us.

The light of the balls stained red again along the way, so each time the air is purified.

"Hey, the colors are dyed red every once in a while, are you sure you're okay?

Since Roddy has been asking me anxious questions, I answer them to reassure him. [M]

"Air Purifying is a magic that purifies hundreds of meters of air around the operator. So if this whole aisle is full of poisonous air, you can purify the air on the spot every time you travel."

"Oh, is that what it is"

As I proceeded that way, I heard something approaching from behind the cave.

"Something's coming! Get the lights ahead of you!

The wizards are instructed to move the magic lights forward.

Then I saw the demon coming from the back.

"Is that, Hell Basilisk!?"

The adventurers get upset when they hear the name.

Anyway, it was the name of a demon who attacked a pre-mine camp before we arrived and put the lives of many adventurers at risk with a special evil eye called Black Death.

"Restorers back off! Attack from a distance to avoid the evil eye of black death! Get the shield out of the way!

Immediately the adventurer with the shield moves forward with his shield so that he does not suffer the evil eye of Herbasilisk.

"Wind Lancer!!"

Mr. Ramies intercepts herbasilisk with wind magic in order not to collapse the cave.

All right, I'm intercepting too!

"Land Lancer!!"

I also attack with magic by rock spears to match Mr. Ramies.

Mr. Ramies attacks from the front to stop the enemy from progressing, and skewers the herbasilisk so that my magic protrudes from directly beneath the enemy.

Herbasilisk was lifted to a rock spear and pierced as he fed his body into the spear at his own weight.

"Oh, hey, I already knocked him out."

"Huh? What? Are we done yet?

I hear the adventurer waiting behind me, and the adventurer with the shield raises a surprise.

Well, because the only thing that attacked me was herbasilisk.

"Because herbasilisk is as soft on the stomach as any other lizard demon"

"I see you had such a weakness"

"No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no

"More than that, my magic wasn't noticeable at all..."

Mr. Ramies using wind magic is the showbone.

"But thanks to Mr. Ramies' magic, which stopped the progression of Herbasilisk, my magic hit the right spot."

"Mm-hmm? Really? Well, yeah."

Mr. Ramies, who was praised and cured of his mood, grinned.

"Aren't you a little choked up, Heavenly Master?

Although Mr. Roddy is staring at Mr. Ramies with a frightened face, in fact, Mr. Ramies' magic made it easier for me to hit my magic, so it was certainly working.

I don't see wind magic, so it's convenient for surprise raids and planting, but it's hard to tell what works, isn't it?

"But I didn't know there was such a monster in such a poisonous air..."

"Herbasilisk is said to prefer dirty places. Perhaps this cave, full of poisonous air, is a place to dress up."

Mr. Ramies' speculation was positive, and even after this, poisonous demons and chimeras attacked us.

"Looks like the poisonous demons and chimeras came all the way around here to escape the Bahamuto and the supernatural demons!

Guess why Mr. Liseau is even in the chimera, whilst scolding the poisonous demons.

"Then maybe there's a path leading here somewhere in the cave. When we send the investigation team later, we have to instruct them to watch out for poison!

Mr. Roddy also argues that he should think later and draw attention to the poisonous air.

I guess we're both thinking later.

"Alas, with so many poisonous demons, you can't keep up with the antidote magic. You were right to bring more mana potions."

Mr. Foca, a monk, is recovering the poison the wounded received by detoxifying magic.

"Shh."

Ms Liliera is waving a sword with attribute-enhanced magic that has allowed her to possess ice attributes, and she is fighting to freeze her demonic nails and mouth so that she is not poisoned.

And the demon attack, which has averted and fought back, prevents poison from entering the body by creating ice shields on parts of his body.

"Huh!

And then you stick the ice shield to the demon's body as it is, making it impossible to attack it the other way around, and then add the attack again.

Liliera is starting to use enhanced attributes.

Maybe I'll teach you some new moves next time.

"Moku!"

And Mohmov was devouring meat without ever knowing if the target would be poisonous.

Don't break your stomach.

... that? Did you follow what I thought Moffmoff left behind?

Oh, boy, I can't help it.

"Oh dude...... those white, they're eating poisonous demons!? Are you okay?!?"

"Well, it's a S-rank pet, and you're okay with it?

"Well, it's a S-rank pet..."

No, it's not like it's okay because it's my pet.

That's how, as you go along in battle, you hear the sound of Bushu from the back of the cave.

"What is this noise...!?"

"Oh, apparently this area is the source of poisonous air. Look, the balls of air diagnosis are flashing, right? That's where the poison air is particularly intense, that is, it tells us where it came from. Normally purifying the air here fills you with poisonous air right away."

Everyone's face turns blue after my explanation. [M]

"So you're saying you can't move on anymore?

"You've come this far by defeating the herbasilisk and poisonous demons in the corner, do you have to give up?!?"

I raise my dissatisfaction that the adventurers can come this far and give up.

Yeah, that's right, you're all brave.

There are no signs of fright in the poisonous air either.

"No, it's easy because it just blocks the hole. Tunnel Extension!!"

I spread the magic of cave expansion all over the space, widening the hole.

Then the sound of Bushu, which until earlier had been heard throughout the cave, was diminished by sight, and it was finally deafening.

"Air Purification!"

And when I activated the magic of purifying the air, the magic balls that had flashed red until earlier changed to blue and never changed color as they were.

"I magically filled the hole where the poison air was leaking when expanding the hole. Now you don't have to worry about overflowing the poison air. All you have to do is purify the remaining poison air."

With my explanation, everyone exhales a sigh of relief.

"Awesome mining magic. How can you deactivate poison so easily"

"Yeah, yeah, it's great! I can't believe we're purifying a whole space surrounded by evil poison! I knew you should have come to the Holy City!

Excuse me, please don't get confused and solicit me, Mr. Foca.

And the poison in the cave isn't evil.

Well, the church people seem to have a strong image of poisonous equals evil powers that can be treated with sacred restorative magic.

"Whoa! You should ask the miners about this too! Wonderful, mine magic! No, I was right to take this request! You'll get more and more new magic knowledge!

While everyone was at ease, only Mr. Ramies seemed happy.

Then, as we expanded the cave while purifying the air, we reached a vastly expanded space.

"Apparently, this is the end point."

Where we arrived, it was a huge underground lake stretching through vast underground spaces.
