Nihonium dungeon, upstairs underground.

I came to refill that because the flamethrower from the special bullet ran out.

The zombies who live upstairs in the basement are carefully slammed through the head one by one, even as they raise the level of growth bullets.

The zombie, who collapses after being struck through the head, becomes a seed of strength and is sucked into the porch.

"Hmm, I hope there were some more easy refills for the special bullets too"

A small pause between the tasks, I tried to blur it somehow.

The easiest way to refill a bullet is usually with a bullet and a trailing bullet.

Usually bullets can be replenished by haggling sprouts and vegetable systems, and trailing bullets can be replenished by haggling garbage.

But special bullets can only be good from monsters in dungeons of nihonium.

Usually bullets and stuff are also produced from regular hagglery stuff, so it's easy to align the quantity, with little effort until you align it.

Compared to that, special bullets take a lot of work because you have to make them yourself out of ingredients.

... I can't do it. I can't do anything about it because this is the only thing I can do to drop it.

Let's at least build a pattern around to make it a little easier.

With that in mind, he defeated the zombies one by one.

"Hmm?"

I stopped and stared in a certain direction.

I felt signs of people.

"Signs of people in this nihonium?

I doubted my senses.

Nihonium produces nothing, usually only drops air no matter how many monsters you knock out.

That's why no adventurer comes but me, and the only exception is Margaret, who produces airboxes.

That Margaret just produces air too, so it doesn't come down below the first basement floor.

This is the second basement, and there can't be anybody here if it's normal.

Put the gun down and take a deep breath.

I regained my mind and looked in that direction again...... I knew I was there.

It's not a mistake, it's a proper sign of people.

I don't care if I feel signs of people in other dungeons and it goes through, but not here.

I wondered why people were coming to this place, and I stopped collecting seeds and headed toward the place where there were signs.

Turning some corners...

"- Don't get too fast!

I hung a rope on the ceiling and saw exactly the man who was about to hang himself now.

The man's neck is still about to hang on the rope.

I pulled out my gun and shot through the rope that was hanging.

Out of balance with a broken rope, the man fell to the ground.

I ran over.

"Are you okay?"

……

The man looked up at me, nodded at first and shook his head shortly afterwards.

"You didn't have to help me."

"I'm not going either. Why are you doing this..."

"Nihonium doesn't have people coming. Because even if I die here, my gear hagglers won't bother anyone."

"No, why are you asking me why I killed myself, not why I meant here?"

The man looked at me again and laughed powerlessly.

"I can't do this anymore..."

This is not good.

There's no reason to leave him alone, and I used the transfer gate to take him back to the mansion.

"Are you calm?"

"... oh"

Nodding man.

The salon of the mansion, Emily, warmed his body with some tea, and he looked a little more energetic than just after there was.

Emily's dishes and teas have a calming and soothing effect.

He pushed the man into the salon and flew him back to Emily Arsenic's place in the transfer room.

With that,

"Thanks. I'm fine now"

The man seems to have kept in mind the re-challenge of suicide.

"Can I ask your name for now"

Exploration exploration, starting with an unusual topic.

"... it's Mattia"

"Right. I'm..."

"I know. Lyota Satoh. He's the biggest celebrity right now."

Mattia laughed mocking herself.

"The boss of Cyclo's largest force, who can solve difficult cases with overwhelming power and follow four spirited men. He's not like me. He's an amazing man."

Mattia crushing almost as if she were messing with me.

"What happened? Why did you kill yourself?"

"There's nothing more I can do."

"Let me talk to you if you like. Maybe I can help."

"... to power?

"I've been solving difficult cases from time to time, haven't I? I was wondering if you could talk to me."

Straight, I stared at Mattia.

I couldn't leave something alone.

I couldn't leave people like him alone because I've seen a lot of them when I was in the original world.

After a while, Mattia told me one thing.

"My family, we started a new business."

"New business?

"Oh. It was about a year ago, we all had a blast at the drinks, and even if we didn't work on the spices, we'd find the most efficient way to defeat each tier of the dungeon, the monster, and sell that method to the adventurer, and it'd be gold."

"Oh, Teaching Corps - No, you mean normally selling know-how"

Mattia nods.

"It was so exciting at the drinking table, but I thought it was just a joke then. But the boss meant it, and the next day he really bumped up the project and ordered me to do it the closest I could get."

……

"Good luck for a year, use all kinds of weapons, and use magic. I've also tried to optimize routes and stuff..."

"You didn't make it."

I snorted even more, Mattia, and I got annoyed as it was.

Well...... right.

In this world, a large number of adventurers dive into and circle the dungeons day and night.

The structure of the dungeon and the monsters that inhabit it hasn't changed much, so much so that the dungeon hasn't changed much since the recent rule that the variety improvement is "two or more with spirits".

So the adventurers are mostly familiar dungeons, optimizing their movements.

There's no way you can find the best new way to do this so easily.

But why commit suicide?

"It's my fault that I didn't get results after a year, because they told me to pay for the damage or knit a good way right away..."

"Whoa."

You're paying for the damage you did on your boss's business order?

Is there such a stupid story?

"So there's nothing I can do about it."

"I see."

I get the point.

The boss has a lot to think about, but for now, it's time to fix what's in front of him.

"Is that optimization okay in any dungeon?

"Huh? Oh, yeah... oh, besides nihonium"

"That's right."

Optimizing nihonium that nobody drops doesn't make it gold.

On the contrary, it's going to be messy money if it's a way for anyone to start dropping.

Well, that's anyway.

"Shall we?"

"Huh? Where?

"Just follow me."

That's what I say. Keep walking out.

Turning around a bit, lost, Mattia stood up and followed me.

Proceed down the hallway and come to the transfer room.

Use the function of the transfer room to set a destination.

A look-alike gate emerges like a swirl of light.

"Let's go"

"Huh? Hey. -"

Half-forced, he brought Mattia into the gate with or without a say.

What came was a dungeon like a Japanese house.

"Ko, where are we?

"It's the twentieth basement of the lantern."

"Lantern!? What's a lantern, that lantern? It's in Philin."

"Oh."

"You're lying... how..."

"I don't care about that for now. Lantern, do you know anything about the 20th floor underground?

"Huh?... Ah, of the new wine"

"Yes, the dungeon I made the breed improvement, that is, the dungeon whose structure has just changed. I'll take a look around now, just remember that and submit it to the boss."

"Huh? But I don't..."

"It's a steeplechase for now. And which one?"

I laughed.

"It's a new and reborn hierarchy, one that will be even more optimized in time. So never mind."

That's what I say, I stare at Mattia.

He bowed his head deeply to me after getting a little lost.

"Thank you"

I laughed furiously and took him around the twentieth floor of the Lantern basement.

I haven't had trouble with stories because I've optimized to defeat monsters from time to time.

I accidentally did it the first time I showed it, and it was an impossible way to do it unless my abilities were S or SS or something, so I imagined keeping my abilities around B, and then I did it another way to show it.

Mattia remembered that and left.

A few days later, the eighth floor of the Nihonium basement.

This day, with Leia, I was improving my luck.

"Mr. Satou!

"Yeah? Mattia. You look good."

"Thanks to Mr. Satou"

Here he is, with a blown out freshness, as if he were someone else a few days ago.

"How's it been since then?

"I stopped, over there"

"Did you stop?

I was a little surprised.

"Why did you stop?

"I taught my boss that one that Mr. Satoh taught me, and it was totally sidelined, and it felt like the boss did it alone, and he was sidelined in the handle"

"Oh......"

Something seems to come to my attention.

Failure is the responsibility of the subordinates, success is the hands of the bosses.

Yeah, it's common... it's common at a level that's a little killer.

"They did that, and I offered them all at once. So I've stopped being a family."

"Right. What am I supposed to say, but that's better."

"Yeah. So today..."

Mattia stepped back and bowed her head deeply.

"Thank you. And I'm here to thank you."

"Right."

Mattia, who gave her head up, had a sunny look on her face as if she were someone else than when it first happened.

It's hard to say subtly that I solved the problem.

"Thank you so much"

When I saw Mattia's face, I thought, "Here we go."
