"A secret... what, it"

Melina asks.

The tone gave rise to slight confusion.

"The map from deep down here, it's not out there, is it? Why do you think that is?

"Why... because it's unpopular. You don't like cartographers because you can't make money from struggling to map them."

"You'll have that, too. But that's not the only source of the map. Sometimes a high level party attacking deep down sells to pocket money"

"What's that?"

"The map hasn't appeared... because the party that went into this dungeon's offense hasn't returned. We're all wiped out. To the boss."

"... Impossible"

I accidentally pinch my mouth.

"Normally, the more discreet a high-level party is. I don't think I'd challenge the boss cheaply. Even if I did, I'd still have the means to retreat."

"Well, listen. From here down to the hierarchy, like I said, poison monsters come out a lot. This is the weakness. Poison is a pain in the ass if you haven't taken care of it, but it can be easily prevented with a bit of a good poison resistant potion. A high level party naturally has that much preparation, and poison monsters have a low status, so we can move on and on without major obstacles. There are a few Dark Class Monsters on the bottom floor, but to that extent, they're in front of the boss room in no time."

……

"So, I think the adventurer who got there. 'It's less expensive, and we'll see how things are in the boss room a little bit'. When I open the door and go in, that's the last thing. Someone never came out of there, and as you can see from the fact that the dungeon is alive now, it's not even cleared."

"You mean you've never withdrawn? Didn't you go home with a return item?

"Probably not. 'Cause - Boss, the door to the room closed all by itself right after the party came in. There's no way you can get out of the entrance, and I'm sure you won't be able to use the returning items. That's an irrevocable boss."

"Oh, that's crazy!

Now Cocor pinches his mouth.

"Non-retreatable boss rooms usually have some kind of gimmick! And dungeons with that kind of boss are most often fitted with similar gimmicks throughout! I can't believe the boss of a dungeon with nothing like this can't retreat..."

"Right. As your sister says, there are often tricks in a non-retreatable boss room. It's like not letting you bring that information back. So - - there must be some gimmick in this dungeon boss room, too. Just the boss here... couldn't attack any high-level party, there's a secret gimmick"

"No, but..."

"Probably not metastases or damage or restraint traps like those in the dungeons... like rules, I don't know what"

"Rules, is it?

"Hmm... I don't know what to say"

He looked difficult, and there Tet cut the words.

He's got something on his mind, but he can't seem to put it into words.

"Is that true? It's very uncomfortable."

Melina said, frowning.

"You've been watching the party that challenges the boss without knowing it. That too, many times."

"I don't know what else to do."

Teto tells me a little bit more.

"I couldn't be sure the first time or twice either. Besides, isn't it a violation of manners to go on someone else's adventure? I didn't even want to be reversed."

……

"Still... I've given you some advice. But you know what? - I don't even ask! Like your sister, you either didn't believe me, or you stormed into the boss room after you believed me. Really, adventurers are just stupid! So this time I tried to make him give up, and I wouldn't even ask."

……

"I'm sure some members of the party who challenged the boss had negative skills. Now that I think about it, maybe that's why I was so desperate...... Still, don't expect such a small dungeon of uncertain boss drops, I wish I had continued the adventure that was at my height... because I was blessed with the party"

To Teto's monologue, I accidentally dropped my gaze.

If you ask me, maybe I was trying to do something reckless myself.

Still, I didn't deserve the party, I didn't have a choice.

Perhaps even to Cocor and Melina.

"... I'm not."

After a long silence, Melina opened her mouth.

"That's not what I was trying to say... that's why I'm in such a situation"

"Huh...?

"There's no deep map out there, which means you came to this dungeon without knowing there was a deep one, right? Why? If you're crate fishing, there's no point in coming to smaller dungeons that usually tend to be shallow, is there? What are you doing here at first?

"Damn......"

"Boss, it's weird how many times I've seen other parties go into my room. It doesn't look like you were accompanying him, and what were you doing there?

……

After a while of silence, Teto says the bumps look bad.

"That's... ask your brother."

"Yes?"

"Anyway, you know your brother."

Melina turns to me.

"Really?

"It's just a prediction. Tell me if you're not."

No reply from Teto.

I go on.

"I guess Mr. Teto was going to take that drop aside the first time another party defeated the boss"

"Ha!?

"Really!?

Teto doesn't say anything in silence.

After all, it didn't seem wrong.

"Why not..."

"You have no choice. If I don't, I won't be able to wear a solo in the boss drop."

Teto also has a sarcastic grin.

"The current level, too, sounds like you earned it from the sidelines of Kill. That's how easy it is."

"... I knew I should stick this guy out to the guild"

"It's a violation of manners, but it's not contraindicated. Nor will the Alliance be able to do anything."

"I wonder. Whatever the miscellaneous fish monster is around here, I don't think the guild would have shut up if he'd taken the Boss Drop from us."

"Exactly. I wouldn't do that from time to time. This time...... only this dungeon boss drop was special. Didn't I?"

Teto says nothing.

"Special..."

"It's the same situation as ours. I really needed an item to erase my skills. Mr. Tetto... because he has negative skills."

I couldn't choose the means because I couldn't throw a party.

Teto still doesn't say anything.

Raise your voice as Cocor and Melina were surprised.

"What, this guy too?

"How do you know that?

"I used a lot of skills during the fight. Four, as far as I can see. All you have to do is anticipate from other circumstances."

High level adventurers often have more skills than people, so it wasn't certain. It's just a prediction.

Because I am, there may have been an assumption.

It turned out to be a hit though.

"What kind of negative skills?

I shake my head to the side to answer Melina's question.

"No, I'm just that far too..."

"[Mummy stealing]"

Block my words - Teto said the skill name.

As if to mock yourself, laugh and say.

"Really, it's a tricky skill."
