It's the second day since we came back from the Devil's Forest, and today we're going to start preparing for war again.
　For now, we'll just build a dungeon today.
　I was actually going to build the school first, but it sounds more fun to build ...... dungeons, so it's no use, right?　I said to myself.

　The place to be created is under the training grounds of the Order and Magical Order.
　For now, I just want to build up my army.
　We'll play with the dungeons when there's time to play again.

　We'll build the training grounds before building the dungeon.
　I'll make sure that basic training can be done at the ground level, and then use the underground dungeons to do the practical training and leveling up.
　Just leveling up won't make you stronger, you know.

　So I spent the whole morning and two hours in the afternoon to complete the Mladin family's training grounds.
　I got more and more passionate while building it, and it took more than twice as long as I expected as I was adding functions to it.
　Anyway, it's good that I made something I was satisfied with.

　Alright, now that the preparations are done, let's start building the dungeon.
　I've built a staircase that leads to the basement, and I've created a big door underneath.
　Then I opened up a little space behind the door.

Can I imagine making this space bigger?　Also, let's put in the image of reinforcing the Knights and bringing them back to life when they die.
　While talking about this, I took out the boss monster's magical stone I got the day before yesterday.
I poured enough magic power into it last night, so it's ready to be used right away.

Now, what kind of dungeon can we make?
Then I used my creation magic.
Then ...... 'Gogogo ......! And with a rumbling sound, the walls and the ground began to move with great speed.
No, it's more like the room I'm in is being carried deep into the basement.
I think the dungeons are probably being built at an awesome rate .

I can't help but feel sick as I move sideways and down, and my triple-circle canal becomes stupid .
'Ewwww . I think I'm going to puke. ...... You're not done yet. ......
　Did you use too much magic?
　d*mn ...... I shouldn't have gone all out just because it was my first time .

　Then I managed to endure a few minutes of nausea, and finally the ground stopped moving.
"Ugh ...... it looks like it's stopped but my vision is all over the place and I don't feel good ......
　I can't get up, I'm dizzy.
　Do you think you could be a little nicer to the surgeon?
　With that complaint, I waited for him to recover.

All right, I'm better. I had no idea that ...... was going to happen. All right, let's go check it out.
　After recovering from dungeon-generating sickness, not car sickness, I managed to get up and walk straight through the dungeon-generating sickness, and appeared on the other side of the door where there was a staircase that led to the ground earlier.

''Hm?　That's a big room: ......
　I looked out and saw an empty space, just a large one.

"Could it be the boss's room with no boss?

"Yes. Yes, sir.
　As I muttered a question, a familiar voice came out of nowhere .

　This voice was ......
Anna?
　It was the navigator's voice, the one that's always helping me.

"Yes, sir. It appears that a copy of me has been implanted to guide you through the dungeon. The data is always shared with me in the goggles, so you can assume it's the same one.
　Yeah ...... I'm not sure what you're talking about, but you're saying that Anna is going to tell me about this dungeon anyway, right?

Okay. Okay, so let me ask you a quick question, what floor is this?

You are on the 25th floor, sir.

'Twenty-five floors?　So it's shallower than I thought.
　It's surprisingly shallow after being swung around so quickly .
　I thought it was shallow but I thought it was the 30th floor. ...... It's a shame because it made me feel so uncomfortable.

''No, I think it's a big enough dungeon for a first one. Usually, early dungeons start at one level .''

Well, if you ask me, dungeons do seem to grow. So how can you make them grow?

'You can do it by using the dungeon core. However, it will require a lot of magic, so we don't recommend you do it now.
　Okay, so it's all magic.

Noted. Let's check out the dungeon core at ......　Where's the dungeon core?　Yeah, it was in a prominent place.
　When I returned to the room I was in earlier after realizing that the boss dragon's magic stone, which I should have held firmly in my hand before creating the dungeon, was missing, I found a large magic stone on a solid pedestal .
　This room is similar to the room where you can get the last skill that comes when you complete a dungeon, but I've never seen a dungeon with a dungeon core this large.
　So this dungeon has the potential to grow as big as possible.

Well then, let's get to work on the dungeon. I've already learned how to use the dungeon core at the mansion in the imperial capital~'
　While saying that, I moved the magic inside the dungeon core.
　Then a three-dimensional map of the dungeon appeared inside the large magical stone.

''Oh~! Is this what a real dungeon would look like? You're right... It's the 25th floor. But still, it's so complicated and complex.


　Each level had paths that went here and there, making it a highly difficult maze that was difficult to solve using a map.

''Yes . Since it's for the training of the Knights, it's set to the highest level of difficulty dungeon.''

Heh. I can have dungeons built for me automatically according to the difficulty level, right?
　The way I envisioned it, it was like using the dungeon core to build your own path and set up your own traps, right?

"It's only the first level that gets built. It's usually just one level.

Oh, I get it. You were the first one to do that.
　Normally it would only be a single level with a narrow range, so it wouldn't be that much of a model, but if you build twenty-five floors on the highest difficulty setting, then you've turned into a ridiculously high performance dungeon.

''Yes . However, to maintain a dungeon on the highest difficulty setting, a lot of magic power is needed. It's also designed to revive the dead challengers, so it requires even more magic power: ...... At this stage, it requires about half the magic power of Leo-sama in a day.
　I'm glad to see that the automatic resuscitation mechanism has been properly adopted . Well, it took a hell of a lot of magic power to do that: .......

''Half of mine or ....... That's a lot of cost.
　Even if I put all my magic into it, that means I can only sustain it for two days, right?
　That's going to tie up your life in dungeons a lot: .......
　It's going to get busier and busier from now on, and once every two days is tough.

''Yes . That's why normal dungeons don't do resuscitation .

I know. It's useless for all intents and purposes. Is there any way to supply magic other than for me to supply it directly to the core?

"Basically, dungeons work by absorbing magic from intruders. That's why dungeons are designed to attract as many people as possible.
　I knew it. Just as I suspected.

Then how come there's a demon?　Oh, if you kill it, you'll get more magic.

"Yes, sir. Yes. The other reason is to get people with more magic power. People with more magic absorb magic more efficiently.
　Ah, so when someone with more magic power is in a dungeon, their magic power is absorbed by the dungeon.
　That's good information .

''And ...... also, there aren't any demons in this dungeon yet . How come there aren't any?
　Can't you just get the demons ready first?

That's because you don't have enough magic. Pouring magic power into the core will automatically generate demons and traps.''
I see...so you didn't have enough magic to complete it.
It's not a dungeon, it's just a maze.

Got it. Then I'll just pour all my magic into it.
　I poured all my remaining magic power into the dungeon.
　I had been having nightmares since I created the dungeon a while ago, so time had passed, and my magic power had recovered to about two-thirds of its maximum.
　With this much, it should be fine, right?

　When the magic power finished pouring out, the red dots began to appear on the three-dimensional map of the dungeon core one after another.
　Starting from the first level, the red dots were increasing like a wave.
Could it be that these red dots are demons?

"Yes. Why don't you take a look at the boss on the first level to see if you can do it?

You're the boss from the ground floor: ......
　I don't think I've ever seen a dungeon like that before.
　That's a lot of magic to get through.
　I should ask Sherry and the others to challenge them to help me supply the dungeon's magic power later.
　While thinking about this, I moved the magic to the boss's room on the first level.
　Then I saw a room with a large goblin and a bunch of ordinary goblins around it.

It's going to be a hell of a challenge from the very first level!
　I don't think it would be this hard even on the tenth floor of a normal dungeon.
　What's hard is that you have to fight the boss and kill the miscellaneous fish too.
　This is ...... a wizard or something like that and we can't go any further.

This is the first floor, and it's way too dangerous. ......
　While looking at the green-painted room with the goblins, I repeatedly muttered words of surprise at the difficulty of the dungeon I had built.

''It's a dungeon with the highest level of difficulty.

It's a high cost.
　Meanwhile, the red dot has reached the 25th floor.

''Oh, it looks like the demon creation is over.
　Then I walked into the next boss's room.
　Then I went to ...... and saw a big dragon there.
　A blue one.
　I've never seen a blue one before. ...... I'm going to appraise it.

　Blue Dragon Lv.150
　Strength: 21,000/21,000
　Magic power: 50,000/50,000
　Power: 310
　Speed: 13,000


　Attributes: wind, ice
　skill
　Wind magic Lv. 7
　Ice magic Lv.6
　Defense Disabled


Yeah, he said this is too strong on the twenty-fifth floor.
　What kind of dungeons would you be in if you added more tiers in the future!

"It's the highest level of difficulty.
　The highest level of difficulty is ...... I bet you love that word, don't you?
