What do you want to do?

　Neptune asked.

'I'll head there for now. I need to know what's going on.'
All right. I'll come with you. I'll meet you there to get everything ready.
Yeah.

　It would be reassuring if Neptune could come too.
　I left him on the spot and listened to him along the way as he and Emily returned to the mansion.

'What's the situation?　Just let me know if Emily knows, tell me.
'I'm not sure either, just that Mr. Celeste is there too.
Celeste?
Yes, I had just met Yoda near Serenity, so I just went to check on him.
Well: ......

　A new dungeon was built.
　Many adventurers entered there to investigate, but the entrance has disappeared.
　One of them is Celeste.

　It's a big deal, and if Celeste is also in distress (or something like that), I can't overlook it even more.

　In the meantime, we returned to the mansion.
　We enter the grounds and go into the vanadium dungeon with them, which is their new home.

'Emily, stay at home. Explain the situation to her when everyone returns.
All right. I'll be ready whenever you are, sir.

　Celeste is also the oldest member of the family, and Emily doesn't seem to be at peace with the fact that she's lost.

You'll be able to take care of the rest. Let's go, Vanadium.
......(country)

　I took Vanadium and used the transfer room in the new mansion to transfer him to the first floor of Seren for now.

　The carbon dungeon is close to Seren, so we used the first floor of Seren as a relay point.
　There are a few fewer adventurers than usual on the first floor of Ceren, and everyone is somewhat upbeat about the situation.

''Hey, let's round up for today.
Yeah, well, you never know when you're gonna have an accident. Let's get home early today.

　From the leaked conversations of the adventurers alone, it was clear that the incident and its effects were spreading.

　I ran out of Seren with Vanadium.
　Outside, even more so than inside the dungeon, the effects were clearly visible.

　A short distance away, a group of onlookers had gathered, and there was an unrest covering them.

　As I approached it and weaved my way through the crowd to get to the center of the commotion, I found another dungeon there.

　The entrance to the dungeon, the part of the dungeon that rises above the ground that is often found in underground dungeons.
　It's similar to the nearby Seren.
　However, it doesn't have an entrance.

　There is a now board in place, and from the direction of the onlookers' gazes, I can guess where the entrance would have been, but there's nothing there, it's just a rock wall.

'Really, the entrance has disappeared: ......

　It's been a long time since I was sent to this world.

　I know that Nowboards are quite special and valuable, and their locations are pretty much fixed.

　Even in dungeons, they tend to be placed in the same place - a safe point away from the monsters, and the ones at the entrance of dungeons are placed in the same place almost everywhere.

　I'm sure it's the same here.
　So it's really weird that there isn't an entrance to the game that should be there, as determined by the now board.

　It's as uncomfortable as the first step to step onto a stopped escalator.

"Mr. Lyota.

　A man's voice called out to me. I turned around and saw a familiar face there.

'Cliff, you're here too?'
Yes, with a group of friends.
Really? ......

　He nodded and looked around at Cliff.
　Cliff, the man who once misjudged himself and took advantage of it, and was hobbled to a black party for a very thin salary of thirty thousand piro.
　When he couldn't see that, he broke his brainwashing and recommended that he should be better off with Aurum because it's mineral C, not tellurian, plant E, but mineral C.

　After that, he woke up and became independent with his friends, who were also scraping by, and now operates as the Cliff Family, under the Lyota Family.

　That, his friends are nowhere to be found.
　And I didn't miss Cliff's expression shifting from impatience to relief.


"Hey, guys, are you in there?
"Yes, ...... while I'm just out with the drops once I'm out with the .......
Well, ......, did you notice anything unusual about it?

　He's a valuable guy who knows what's going on inside. I asked him to get some information.

'No, it was a pretty normal dungeon. No level changes, no terrain changes, no restrictions or anything like that, it was very orthodox.
Well: ......

　So there are no omens or anything like that.

d*mn it, what the hell is going on inside?
'Is there any way to do it?　Vanadium, do you know what it is?
...... (pulp)

　Vanadium shook his head with an apologetic look on his face, and then, just like that, he slumped down.
　I took a deep breath and patted Vanadium's head, mending my expression.

'I'm sorry. It's not your fault.

　That made Vanadium look relieved.
　However, we can't just sit on our hands like this. Something--.

''Kyaaaaaah!''

　A woman's scream went up, a breath of air delayed and a murmur broke out.
　I looked around to see what was going on and saw that all the onlookers around me were looking at the same spot.

　I followed their gazes, and when I did, I saw an adventurer lying in a pool of blood where the entrance seemed to be.

''d*mn!''

　He approaches the adventurer, draws his gun, and fires an infinite number of recovery rounds.
　The bloody adventurer's injuries heal in no time at all.

'Oh, ......'
You were seriously injured, but in a heartbeat.
Lyota, Lyota, Satou?

　Someone called my name, and immediately afterwards, a cheer erupted.

　I guess the cheers are meant to imply that a savior has appeared in this situation, but the situation is not good.

'Is this the person who entered the dungeon?

　Then I look around.
　Then, one of the onlookers.

'I know him, he's staying at our inn and he's a wizard who's been in the dungeon since this morning.
Okay.
Was the person inside kicked out?

　Cliff asks me.

'Maybe so, but it gets worse than that.
Well, is it bad?
Do you have a buyer in mind?
I'm from The Swallow Repayment, Mr. Sato.

　One of the men from the crowd of onlookers replied.

'Are the drops being sent out of the dungeon?'

　I was the first to use and popularize the magic cart drop item transfer.
　It's now quite popular among adventurers, although it's a luxury item.

　A lot of star-carrying adventurers would definitely bring in a magic cart with a transfer.

''No, we don't have those either.''
Okay.
What's going on here, Mr. Lyota?
'The adventurers are trapped in the dungeon, and as long as they can't get out, we have to defeat the monsters to ensure their safety.
Yes.
'But the drops can't get out. Then the drop items from the monsters you defeat will continue to accumulate. If it increases beyond a certain point, it will be out of the human realm (、、、、) and hatch into hagglers from one end to the other. As a result, the dungeon will always be full to the maximum number of monsters in the dungeon.

　The people around me buzzed even more when they heard my analysis.

'Then the trapped adventurers won't be able to rest properly, they'll be brought into a war of attrition.
What can I do? You mean, someone like this guy who gets hurt so badly?
...... Will you be thrown out with a serious injury, or will you run out of power and fall inside ......
Let's tear down that wall and pry open the way out!

　Cliff says, and a few adventurers try to move around him.
　Some of them will have friends inside just like Cliff, they must be in a hurry.

'Wait!'
Don't stop me, Mr. Lyota. It's Mr. Lyota's idea that his people are in danger inside.
We can't destroy that thing and hope it opens the door. I just need you to give me a little leeway. I'll give you five minutes.
Five minutes?
Yeah, there's one thing I want to make sure of.

　As he said this, he stopped trying to force an exit.

'If that Lyota Satou says so,'
Yeah. Maybe for five minutes.

　For now, it looks like we've been stopped.

'Cliff, stay here and watch everyone. Vanadium, let's go!

　He ran out with Vanadium in tow.
　When Seren arrived, he ran in at full speed and returned to the mansion once he got there.

　　　　　☆

　Five minutes later, I returned to the front of the carbon dungeon with a new Niftonium in tow.

　A group of onlookers were whispering to each other about the identity of the human I had brought back.

I'm here, Nihonium. Can you do it?
Do I have to stop you?
Yeah. Please.
...... One thing I'll say no to, though.

　Nihonium glanced around.
　It was a cold stare, somehow.

'I don't care about the humans. I am you, so I will help you.'
Thank you. That's very helpful.
......

　With a complicated look on her face, Nihonium held up her hand and called out to the monster.

　Nihonium's dungeon master, a ghostly woman.
　It stood in front of Nihonium.

　Instantly, the presence of the Dungeon Master enveloped the surroundings.
　The adventurers reflexively braced themselves, and the non-adventurers shuddered in confusion.

''How's it going?''
You're not supposed to be here.
Well, thank you!

　I took Nihonium's hand and thanked him.
　Nihonium is bemused and confused.

　Now, I have to explain what just happened and reassure everyone--

'It's Tennysin!　That's the girl who was there all the time at Tennesin!

　Someone shouted out loud.
　It was like someone who knew what happened then.

　Amidst the murmur, the situation spread like a ripple around that person.

　In the construction of the dungeon city of Tennesin, the nihonium that had held back the monsters in the construction of the dungeon city. The dungeon master's ability to make even the monsters in nearby dungeons disappear.

　In other words, the monsters in the carbon also disappeared.

''Selenium's monsters will also disappear, but that can't be helped--''
Thank you.
What?

　Nihonium is amused by the voice that arrives from the other side of me.
　She turns around fearfully.

'Thank you!'
You're safe!
You're a goddess of salvation!

　The assembled onlookers praised Nihonium with their mouths full of praise.

　Unaccustomed to being praised, Nifongnium gave me a puzzled look and asked me for help.
　I just smiled and watched.
