Tensei Shitara Slime Datta Ken (WN) 2018

c101 -Smooth Plan

We went to the last floor where Veldora will live and arranged the interior.
I take out all of the furniture out from my stomach and set them in room cordoned off by blocks.
Atmosphere is really important, so I can't let the public see it.
I copied and prepared some items that Veldora likes.
And after we finished decorating the room, we proceeded to the center of the 100 floor and had Veldora release his aura.

Veldora released his aura carefully and managed to do so without an accident.
The inner walls of the room were created out of ore.
It going to turn into demonic steel soon after getting bathed with magic power after all, so it's a simple mod wall.
This way, we can save a bit on costs.
By the way, the first floor of this dungeon is a square room 250m wide.
It's the same size as 4 Tokyo Domes, but as you continued further down, the size got smaller.
The dungeon was created this way so the aura could spread well.
Veldora's room is 100m2 wide.
It's seems quite big, but if Veldora get into his real form, it actually quite small.
It was created so it can be expanded if it's ever inconvenient.
The dungeon is under Ramiris control, so it can be customized freely to some degree.
The aura is seeping up to each floor as planned.
Since there's no wall to block the way, it fills the room without disturbance.
All we have to do now is to wait until the monsters spawned.

After Veldora turned back into his human form, we moved on to the next step.
First, about traps

Poisoned Arrow ●●● Arrows smeared with poison come flying out of nowhere
Poison Swamp ●●● Swamp that is really poisonous. If you fall into one, you'll get poison damage and abnormal status
Turning Tile/Mat ●●● Driving your sense of direction mad. Feel the importance of mapping!
Moving Tile/Mat ●●● A floor that moves all by it own. Really scary.
Cutting Thread ●●● Pass by it without realizing, your head comes off. Combined with Moving Floor for brutal results
Pitfall ●●● Rather than the damage dealt by falling down, what's awaiting you when you fall is scarier.
False Treasure Box(Mimic) ●●● Great, a treasure box..? Too bad, it's ME!
Laughing Treasure Box ●●● Great, a treasure box! Die laughing.
Monster Room ●●● Hi there! Finally, a feast.
Sealing Room ●●● Turn a fire on and.....
Darkness Floor ●●● It's a common sense to bring a torch you know. If you don't have one, we could sell one for a high price, how about it?
Low Ceiling Floor ●●● I don't want to meet monster while crawling~
Terrain Effect Floor ●●● What the hell is this?! Why there's a volcano in a dungeon!

I listed all of the trap I could think of.
Almost all of them are possible.
It's just the Terrain Effect Floor is too difficult. Well, volcano is impossible as expected.
I was imaging having blazing floor, freezing floor, or blizzard floor that makes traps from natural disasters, but.......

「Impossible. I don't have the energy to maintain something like that!」

As expected, it's impossible.
Well, I might've asked for something really absurd.
And when I was going to give up on that plan,

「Do you want me to tame a fire dragon or ice dragon from somewhere?」

I hear the voice of someone that shouldn't be there.
As I turn around I could see silver haired twintail.

「Eh.....? Why are you here? Milim....」

100 floors underground.
In the other word, in the last floor of the newly-built dungeon, a beautiful young demon lord is smiling with a complacent smile.

「Fufun. Somehow I feel that you're doing something fun. To think you were courageous enough to exclude me」

She said while getting arrogant and arching her back to emphasize her pitiful chest.
As usual, she's dressed all in black with dragon knuckles–that are emitting a dim light and hardly fit–on her hands.
Still, as expected. She's really sensitive to this kind of conspiracy.
No doubt, it's impossible to hide things from Milim.
In the first place, it's impossible to reason with Milim.
Just because she appeared here, there's no need to be surprised.
Milim and Veldora glared at each other, but afterwards shaked hands and seemed friendly.
If the two of them fight with each other, it'll be a serious matter.
Thank goodness they have become friends.
