Shitara Slime Datta Ken (WN)
Plan Seamless

We went to the last floor where Veldora would stay and arranged the interior.

I took out all the furniture from my stomach and placed it in a room bounded by beams.

The atmosphere is very important, so I can't let the public see it.

I copied and prepared some items that Veldora liked.

And after we finished decorating the room, we proceeded to the middle of the 100th floor and asked Veldora to let go of her aura.

Veldora released her aura carefully and managed to do so without accident.

The inner walls of the room are made of iron ore.

It would turn into demon steel as soon as it was bathed with magic power, so it was a simple mod wall.

This way, we can save a little bit of money.

By the way, the first floor of this dungeon was a square room with a width of 250m.

The size is the same as 4 Tokyo Domes, but as you continue down, the size gets smaller.

The underground prison was created in this way so that its aura could spread well.

Veldora's room is 100m2 wide.

It seems quite large, but if Veldora becomes its original form, it is actually quite small.

It is made to be expandable if it feels uncomfortable.

The dungeon was under Ramiris' control, so it could be adjusted freely to a certain degree.

The aura seeped into each floor as planned.

As there were no walls blocking the path, it filled the room without any distractions.

All we have to do now is wait until the monsters appear.

After Veldora returned to her human form, we proceeded to the next step.

First, about the trap

Poisonous Arrow ●●● Poison smeared arrow flew out of nowhere

Poison Swamp ●●● Highly toxic Swamp. If you fall into one of them, you will get poison damage and abnormal status

Tiles /Play Mat ●●● Makes your sense of direction crazy. Feel the importance of mapping!

Move Tiles / Mat ●●● Floor that moves by itself. Very scary.

Cutting Yarn ●●● Pass unwittingly, your head loose. Combined with Moving Floor for brutal results

Trap ●●● Rather than damage from a fall, what awaits you when it falls is more frightening.

Fake Treasure Box (Mimic) ●●● Great, treasure box ..? Too bad, it's ME!

Laughing Treasure Box ●●● Great, treasure box! Dead laugh.

Monster Room ●●● Hello! Finally, feast.

Sealing Room ●●● Fire and… ..

Dark Floor ●●● Is a natural thing to carry a torch. If you don't have it, we can sell it at a high price, how?

Low Ceiling Floor ●●● I don't want to meet monsters while crawling ~

Medan Effect Floor ●●● What is this ?! Why is there a volcano in the dungeon!

I listed all the traps I could think of.

Almost everything is possible.

It's just that the Medan Effect Floor is too difficult. Well, a volcano is unlikely as expected.

I imagine a smoldering floor, a frozen floor, or a blizzard floor that sets a trap from a natural disaster, but …….

“Must be sure. I don't have the energy to sustain something like that! 」

As expected, it was impossible.

Well, I may have asked for something very unreasonable.

And when I'm gonna give up on that plan,

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

I heard the voice of someone who shouldn't have been there.

When I turned around, I could see a silver-haired twintail.

「Eh ……? Why are you here? Millim…. 」

100 Floors underground.

In other words, on the last floor of the newly built dungeon, a beautiful young demon lord smiled with a satisfied smile.

「Fufu. Somehow I feel you're doing something fun. To think you're brave enough to exclude Me 」

He said as he became arrogant and arched his back to emphasize his pitiful chest.

As usuaYa, she was dressed all in black with a dragon knuckle – that emitted a dim light and barely fit – in her hand.

Still, as expected. He is very sensitive to this kind of conspiracy.

Undoubtedly, it was impossible to hide anything from Milim.

First of all, it is impossible to negotiate with Milim.

Just because he appeared here, there was no need to be surprised.

Milim and Veldora glared at each other, but afterwards shook hands and looked friendly.

If the two were to fight each other, it would be a serious matter.

Thank goodness they became friends.

「Sorry about that. I have no intention of leaving you. I'll invite you after 」 is finished

“Betulkah? But it would be more fun to participate from the beginning when doing something like this 」

「Well, that might be true. By the way, is your country okay? 」

He is also a demon king.

Moreover, after merging his territory with the former demon king Frey and the Karion region, it should have been rather large.

Is it okay for him to play and walk like me? (Hmm, Me? I'm doing fine. Everyone's very nice, so I better not bother them)

After hearing my question, he shifted his gaze.

「Well, it's okay. Look, I'm absolutely amazing anyway …….

I've never come here on the run because I hate studying! 」

I'm seeing.

Frey or the others examined and summarized the state of the state and tried to teach it to Milim.

He hated it and ran to this place. That might be the real situation.

“Cannot be! I'll join whatever happens! 」

Before I said anything, he refused.

As expected. His intuition was sharp as always.

Well, whatever. I'm not the one who gets scolded anyway.

Than that, though,

「Alright, I'm not the one to be scolded, so let's put the matter aside.

What did you say earlier, taming the dragon? Is that possible?”

「Ugh…. I will really be scolded…? No but….

Can't help. There must be danger when you get out.

It was possible to tame the dragon. If you want to, should I tame one for you? 」

「Ooh, can I count on you? What species are there? 」

Milim was afraid of being scolded, like a child who missed his homework to go play.

Well, how else. That's the path he took.

After overcoming his worried expression, Milim's mood changed easily as he taught us about dragons.

It seems Veldora is not interested at all.

Ramiris says something like 「What are you doing come to this place!」 Just to be glared at by Milim and get caught ..

From the explanation of Milim, there are 4 types of dragons.

Fire dragons, ice dragons, wind dragons, and earth dragons.

There are some that acquire special or unique evolution, but these are only four types.

As expected, it was impossible to tame a dragon king, but as long as it was not a king, it was possible to tame an adult.

With this, having an effect similar to the field effect is possible.

So we'll let the dragons live downstairs.

I don't really know how powerful the dragon is, but in practice every dragon has at least an A rank.

It was a level that 6 Holy Knights could defeat.

Dragon element will definitely increase the difficulty. So – while being carefree, of course – I set the dragon floor.

In order of strength, api> es> wind> earth.

Or so it would be if the dragon was young. The order might change if it's the old one. That is, a dragon capable of using all of its power will emerge victorious.

If it is a sequence of powers only and become like that.

As of,

The 99th floor was the Flame Hell Floor. Covered in a high-temperature fire, the last gate. Heat resistant equipment is required. The one who waited before was !?

The 98th floor is the Ice Hell Floor. If you stop, you die. Can you hold it with cold-resistant equipment?

The 97th Floor is the Lighting Floor. The light thread fell from the sky. Whether you can break through this floor or not depends on your luck!

The 96th floor is the Tremor Floor. To mock those who made it this far, a violent earthquake will befall you. Feel the wrath of the dragon!

A super hard terrain floor has been created.

Dragons could use the aura that Veldora released as food, so they could stay here without any problems.

No need to break this floor. Just let the tamed dragon Milim make a nest here and everything will be fine.

Create a safe zone every 10 floors.

There was a boss room before each one, so they could only access it after they had defeated the boss.

There, they could buy magic stones, sell drops, and buy potions at a very high price.

Building a tavern or restaurant might be a good idea, but wouldn't they just walk out of a dungeon if they wanted to take a break?

All right, I'll decide that as time goes on.

The first floor's difficulty was only for testing. So every beginner can finish it.

The road is wide, so getting lost is unlikely.

Nevertheless, the width of 250m is quite large. This will be a floor that makes you run a lot without any results/income whatsoever.

From then on, starting with the 2nd floor was not that easy.

It's time for a trap.

Even though I said it wouldn't be easy, in reality there wasn't a single brutal trap up to the tenth floor, so I'm sure they'll continue without great difficulty.

Immediately facing a death trap would hinder people from continuing, so it was impossible.

This way, while arguing about this and that, the four of us proceeded to organize each floor.

And thus, after three days, we were almost done refining it.

We nodded at each other with smiles on our faces, leaving the dungeon feeling satisfied.

※ needless to say, the dungeon was filled with monsters as we went there again.

Milim came out to tame the dragon.

I don't really mind monsters being destroyed, but it's not okay for dragons.

We designate all the tamed dragons as subordinates of Ramiris.

If Ramiris was killed, he would disappear, but his subordinates could reappear at the recorded place.

This was the reason why he wanted Beretta so badly.

Even if Ramiris did not have any power, within the dungeon, Ramiris' army was invincible.

For Ramiris who had no subordinates, it was just a meaningless invincible skill.

Beretta herself served us tea without any complaints that were busy fulfilling the function of the waiter.

As Beretta seems to agree, working for Ramiris may not be so bad.

「With this, I finally got a real subordinate... ..!」.

Ramiris is clearly emotional.

He's probably very lonely. So while looking at Beretta, I,

「Oi, Beretta. Do you want to be Ramiris's regular servant? 」

I asked Beretta.

I've been thinking about this for a while. If Beretta wants it, I'll let her change her loyalty.

If Beretta doesn't want to, I'll prepare a new subordinate for Ramiris.

Beretta answered, though,

「Is it okay? Then I will swear allegiance to Ramiris-sama, as his servant 」

He said without hesitation.

Isn't that nice, Ramiris. You are loved unexpectedly.

I nodded, though,

“Good. Well, then Beretta. From now on, you will work under Ramiris! 」

I declared, lifting the main key and transferring it to Ramiris.

Which of course was astonished by what had just happened.

“Ay! Thank you so much for everything until now. I will not forget the pleasure of letting Me be born into this world 」

「Don't worry about me. From now on, work hard and protect Ramiris 」

“Ay! Even at the cost of my life! 」

Let's trust him. If it's Beretta, I don't have to worry.

Transfer completed without any problems. From now on, I'll just be a sub-master.

As long as nothing happens to Ramiris, Beretta will only listen to Ramiris' orders.

Ramiris who finally managed to grasp the situation pranced around happily.

He's probably very happy.

But, it's okay.

Controlling a dragon within a dungeon alone might be too difficult.

So if Beretta was there when she needed her, there would be no problem.

It seemed Beretta also did not want to give up the position as the first slave since Beretta had served her for a while.

Veldora and I were getting sick of seeing Ramiris prancing around.

Being a formal lord-servant relationship, Beretta became immortal inside this dungeon.

The servant can only live again in a predetermined location, but there is no limit to the resurrection.

With a sufficient number of troops, Ramiris' ability was terrifying.

And since he was the owner, this ability was still not revealed.

I won't tell him, but depending on its use, it could easily affect any battle.

Even now, having Beretta with unlimited rebirth was too overpowered.

Now, we also added the dragon Milim.

There was a chance that this child would soon have an unusually strong power in his hands.

But, anyway, it was Ramiris. There will be no problem.

This sweet elf was just a lonely little boy.

The revival item called the bracelet of revival was also recognized by Ramiris, so anyone wearing it would not die.

But, it would have no effect outside of this dungeon.

If this is not fully explained, there is a possibility of misunderstanding.

And then while confirming things, the dungeon was established steadily.

「What is this airtight room for? is this also a trap? 」

For that question,

「If you suddenly enter a room without air, you will fall because you cannot breathe. Worst – dead.

Be careful in front of any room. It's a strict rule.

Check for toxins in the room, measure the air concentration. If you can't do at least this much, you won't be able to last long.

At worst, you should use wind magic for ventilation 」

I replied, it seems like he doesn't understand.

「Well, I know that this is a terrible trap.

Ye…. I've been thinking about this for some time, but you are a scary guy.

But, it's reliable. I won't be able to think of this kind of trap alone…. 」

Ramiris said while looking at the trap in awe.

So that's what he thinks of me. Yeah, I liked the game in the world I was in before, so this is a trap I'm used to.

If you tell Me to finish it in real life, please be different.

There is hardly anyone who is not affected by the poison and does not need to breathe like us.

I think this is going to be a brutal dungeon.

The finished work can hardly be described with just “brutal”.

(Well, if you add a monster to that type of vicious trap, of course it will become evil)

I felt like I heard a voice, but it was probably just my imagination.

However, I'm sure I'll hear it again soon.

After finishing the dungeon making, I returned to the city.

Veldora and Ramiris will probably be happy to finish the rest on their own.

They're very interested to see I set a trap ..

They also asked to allow them to set it up, but I refused – mainly because I wanted to avoid the sick joke before the tenth floor.

Otherwise, the customer (adventurer) will break his heart or mind and will not be able to continue.

However, I decided to leave the rest to them on the condition that the floor should be passable.

The 95th and 94th floors will probably be absurd floors, but that's okay.

Floors 91 to 93 are untouched. Milim might want to do it, so we'll prepare it later.

So, I leave the rest to them. It's good to see them enjoying themselves this much.

By the time I returned to the city, Myormiles had arrived.

He must have prepared himself very hastily. His arrival was much faster than I had planned.

I led him to the mansion I had prepared earlier and left the rest to Rigurdo.

I thanked Myormiles and explained to him about the new incident.

I explained the location of the arena and the plan to build a tavern town there.

I also told him about the plan to attract adventurers with the newly built dungeon.

Rigurdo and Myormiles were surprised to hear it and it turned into a pretty long discussion.

Rigurdo wanted to discuss the type of people who would come here from now on.

Myormiles discussed the opening of the arena and the basement.

After listening to their opinions, we proceeded to discuss the necessary resources.

They quickly became good friends.

I told Rigurdo to treat Myormiles as the official leader of the business division.

I also told him that Myormiles would get a second position as the leader of the publication.

Rigurdo nodded, and contacted individuals who would benefit from the division.

Thus the preparation continues.

Myormiles were accepted as residents of Tempest with ease.

I just introduced him and let the others introduce themselves.

The flow was so smooth that it surprised me.

After all, after seeing Myormiles work ethic, they could not have any complaints.

Myormiles showed that he was able to understand the abilities of the subordinates assigned to him.

And, including his entourage, he assigned jobs to each member individually.

Seeing the hierarchy complete in an instant was somewhat refreshing.

Myormiles is very active as it is in charge of two divisions.

Now, for invitations to various leaders and puppets.

Excluding the people I know personally, we sent out invitations on behalf of Myormiles.

Influential nobles and wealthy merchants in every city.

His progress was so fast that you would have thought he had done this his entire life.

We also draft procedures and fees for upcoming events.

Not just planning and management, but everything went smoothly on all fronts.

Looks like I picked the right guy.

Perhaps out of all the ideas I have put into practice, choosing Myormiles is the best.

If he wasn't here, the chances of things becoming chaotic were extremely high.

Only with our strength can we not do this well.

I was so lucky to meet such a good person.

Myormiles also feel fascinated by the food, environment, and comfort of this city.

“Must be…. This is impossible! It was even more convenient compared to the royal capital! 」

He kept saying until it basically became his catchphrase.

I'm glad he likes it.

Then again, Myormiles' reaction was the ultimate proof that everything would be fine.

And Myormiles himself knew that.

「Rimuru-sama, there is no way this plan will fail.

With everything there is, anyone can make it work! 」

Myormiles said.it was full of excitement.

I think there are people who overdo it, but I'm glad to hear him say that.

And as the preparations went on, foreigners began to arrive at the city.

I feel the summer approaching.

And it's near us!
