'Sad meow!　It's so sad that the moment it starts, it's over!
It's not fair!　Isn't the Lord supposed to be waiting for you at the bottom of the dungeon?　What's it doing at the entrance?

　S-class adventurer Black Cat and Golden Bat.
　The exploration of the first dungeon has been successfully completed.
　The reason, because the last boss is at the entrance.

　The setting is so diabolical that first-time killers and frame-up techniques seem cute.
　Everyone who takes on Sensei's dungeon without permission dies like this.

''But!　There's always a strategy for every dungeon!
"'What did you say? Nyan!

　Mr. Silver Wolf says with a smug look on his face.

I'll give you a hint. That the No-Life King in this dungeon is not just any No-Life King!　In terms of strength, as well as strength, if we encountered an ordinary, vicious and cruel Immortal King in the first place, would we be able to linger on for so long?
''If you put it that way, is it true...?
From what we've seen so far, it wouldn't be strange if they didn't kill all of us long ago...

　But they are alive.
　What does that mean.....

'That means the teacher is a no-life king who can talk the talk out of the ordinary!　If you ask politely, they will allow you to enter the dungeon!

　Silverwolf-san........?

You talk about hints, but you give away all the answers.
"The idea of 'being polite' and 'asking' comes from these guys?　I got anxious in the middle of talking about it...!

　Looking at the attitudes of these two and other things, Silver Wolf-san's fears were very much in agreement with me.

''There's nothing I can do if I'm rude to an otherwise friendly teacher, so I'll take the initiative to set an example here...!

　Mr. Silverwolf, bowing to the teacher, says.

'Let me explore the dungeon!　Please!　.... so why don't you guys follow suit!
''Oh, please, nyah-nyan!''

　The two S-classes were overwhelmed by Silver Wolf-san's power and bowed their heads.
　They are not the only ones who can do that.

''Mm, okay.''
""Yay!"

　He was generous, as always.
　The same teacher as always.

I'm sure you've all heard of him. It's important to be polite, and if you have the title of first class, you should behave accordingly and be a good example for your juniors.
Yes, I understand!

　The only one with a good response was Mr. Silverwolf.

'Alright!　We've been given permission to go on a search!
I'll be the first one to reach the lowest level!　If you can't find it, at least I'll be the first to conquer it!

　The other two are now focused on the dungeon and don't give a d*mn about anything else, so they rush in.

It's a good thing that they are not the only ones.

　Silver Wolf-san breaks down in tears.

"You are having a hard time.

　The doctor put a hand on his shoulder to comfort him.

　　　　* * * *

　And two top-notch adventurers plunge into a dungeon in earnest.
　But when it comes to being top-notch as humans, the two are not necessarily the same.

''Whoa!　The interior of the dungeon is in order!
"A basic characteristic of a dungeon with a master!
"The monsters are in order!
"It's easy to aim for when there's material you want!
"There's a dead end!
'There's a staircase over here!
"Down the stairs.
'I'll be up when I get down!

　..........
　I'm so moved by this that each of my daily life's uneventful things is like an important thing.

　Golden Bat and Black Cat, who were happily exploring the dungeon, were as excited as children in a theme park.

I'm sure that's what happens when a genuine adventurer enters a dungeon for the first time. It can't be helped.

　Silver Wolf-san said as he grew dimmer.

　The teacher's dungeon is organized pretty well for us to collect materials easily.
　That's why we can easily get to the bottom level if we want to.

　Golden Bat and Black Cat are both top-notch adventurers to begin with, and they easily conquered the dungeons.
　Even so, they seemed to be overwhelmed by the preciousness of the monsters that appeared.

'Alright!　Next, the dragon dungeon is nearby!　Let's go, Black Cat!
Let's go!　I'm so moved that my side hurts. I'm going to take a break...!
'Oh my God!　This is why third-rate adventurers...?

　And an insatiable appetite to seek out new dungeons.
　Did their insatiable hunger push them to the S grade........?

''But it's only humbling to be impressed........ Why wasn't I the first one to discover this dungeon.......!

　An S-class adventurer who complains about something I don't understand.

''The Golden Bat has the record for the most newfound dungeons, you know.

　Mr. Silverwolf explains.

'Finding an undiscovered dungeon that no one else has seen is one of the greatest achievements of an adventurer. For a guy who's racked up that achievement so many times, it must be frustrating for someone else to make a new discovery.

　This dungeon has been seen by many people, including me...?

"Yes, meow!　This guy's inquisitiveness is annoying in some cases!''
'What?　Doctor?

　I thought it was Black Cat's statement, but it wasn't.

　The cat suddenly jumped on my shoulder.
　Don't think it's just a cat, but its true identity is one of the No Life King of the Immortals, commonly known as the Doctor, who lives the longest among them.

"Wow, Dr. Nyan!　Long time no see!
"Are you also working diligently to perfect the art of the cat?

　Mr. Black Cat and the Doctor.
　They are both cat characters, and they both get annoying when they are together.

　Since we ran into each other at the dungeon attack race the other day, we seem to have become good friends.

I'd like to know what you're talking about.　It's almost as if you knew this person?
'Huh, what are you talking about?　Black Cat is enough for you to know a talking cat or something, right?

　The golden bat doesn't seem to know the doctor either.

Well, it's understandable that you don't know him. I've wiped your memory.
What?
"This guy's habit of finding dungeons is a nuisance. I don't want to expose my dungeon to the public's eye, but he finds it without any consideration.

　Speaking of which, I've mentioned it before.
　The Doctor has been in existence for far too long and is hiding his main body, which has been decaying, sealed and hidden in his dungeon.

　It is the Doctor who emits a psychic wave type of thing from it and sees the world through the cat he receives.

　In other words, the main body hidden in the headquarters is the doctor's kryptonite, and it's a bad idea to let him know where you are.

I don't know the exact location of the doctor's dungeon, either.

　A completely unknown doctor's dungeon that even the doctor has not been able to grasp.

'If there is such a dungeon, I'll find it!　My next target is set!

　The Golden Bat was delighted to hear the story, but....

I'm in trouble because I'm going to find him.
What?
I'm not sure how many times I've seen it. It's a good way to get rid of your memory and get back to your hometown, but even so, they still find you again. I've erased my memory more than ten times now.
'What?　Huh?　What?

　Mr. Golden Bat's eyes fluttered, not understanding what he was doing.
　Silver Wolf and Black Cat who were there were also overwhelmed and lost for words.

I'm not sure what to make of it, but it's a very compassionate thing to do. If it was any other no-life king, he would have killed it the moment it invaded his domain.
It's tricky because if you kill them, the next ones will follow. It's best to just forget all about it.

　So you're saying that this S-class adventurer who is so good at discovering new dungeons has discovered these same dungeons anew, without even realizing that he's forgotten about them?
　You're forgetting that fact as well.

I'm going to tell you not to find my dungeon anymore. You can't keep sending them back and forth.
"I've actually discovered more dungeons than I know...?

　Same thing over and over again.
　Maybe he's got a terrible talent and mind of his own.

'And by the way, so is this dungeon. The saint doesn't want his dwelling place to be open to the public.
''Well, if the dungeons of Eagles and Veerle are registered with the Adventurer's Guild, the saint's farm will be noisy. We mustn't bother the saint.

　Even the teacher joins in and says, "I'm going to erase these guys' memories again today.

"I'm going to erase their memories again today, so we won't have to worry about it.
''Eeeeeeeeeeeeeeeeee?!''

　Hearing that, the two dungeon junkies, Golden Bat and Black Cat, all screamed like the end of the world.

''Oh no, wait!　Such a great dungeon and you forget about it!
'That's not true!　That's not a good idea!　Me and the doctor?

　I cling to him, but he's the absolute one.
　We must not forget that.
　You will be able to find out the best way to get a good deal more about it.

It's a good idea to be able to have a good time with them. If you take a couple of conditions, you can leave your memories untouched.
Really?　That's what I'm talking about.

　It's annoying.

The first thing is, of course, not to tell anyone about this place. But I'd like to ask you to do something else, too.
'Tell me what you want!　If I can dive into this wonderful dungeon again, I'll make any promise I can to you!
Why did you just say that?

　In fact, this far has been the plan so far.

　In the first place, why did we invite all the S-class adventurers to join us?
　The purpose of the project has been kept under wraps until now, but it's time to find out.

　We really needed their help for the new event we were about to start.
　I tried to negotiate with them.
