“So do we just need some light, then?”
“Yeah. Any ideas, Shion?”
“Yes! We can open a hole in the wall to bring in some light…”
“No, you idiot!”
Shion scowled at my immediate refusal. This was called the Sealed Cave for a reason. The walls were incredibly solidly built. Maybe you could smash a hole in them if you applied all your strength to it, but that ran the risk of a massive cave-in—and losing all Gabil’s noteworthy cultivation progress. I hated to pop Shion’s balloon like that, but I had to.
“It’d be nice if we could run some electricity through here,” I muttered to myself.
“What’s that, boss?”
“Could you tell me what you mean by that?”
It seemed to grab Kaijin’s and Vester’s attention. So I gave them a basic rundown of how electricity worked back in my realm, projecting the image of a light bulb into their minds.
“I see… Apply heat to a metal filament to generate light, then?”
“Hmm. Yes, it is quite astonishing. The luminescent moss here won’t provide enough light to work with. It is certainly something we need to develop.”
I was expecting to generate the required heat via electrical resistance. Instead, they proposed a solution involving a magic circle to compress magicules inside. Much like how a magic-imbued sword emitted a faint glow, applying a little magic engraving to metal would apparently let it light up. We’d be using magisteel for the metal, I assume—the best kind of raw material for swords, and very compatible with magicule usage. It’d generate a lot of light, as well as provide heat resistance and durability—and the way it readily soaked in inscription magic meant there was little need to test anything else. It’s pretty valuable stuff, but I had a vast supply on tap—a supply that I kind of mined from this cave, so I might as well use it.
Metalwork and carving work were mostly done in Dold’s wheelhouse, so we decided that Kaijin would discuss matters with him afterward. I gave Kaijin the necessary materials, and with that, my role in the project was over. The three had what they needed, and I figured I’d leave it to them.
“You know,” I ventured, “if we’re going to have some light soon, why don’t we just build a laboratory in here?”
“Could we?!” Vester excitedly replied. “I do rather like the relaxed atmosphere in this cave. Having such a ‘secret lab’ is a concept I always enjoy.”
I guess Vester was more childlike than I thought. His eyes sparkled as he said all this, so I couldn’t walk it back. For now, though, I thought it best to remind him of the local dangers.
“You sure about that, though? There are evil centipedes all over the place. That’s like a B-plus right there.”
“Hmm? Not a problem, I would say. I have dabbled in magic myself a little, and I actually have quite a bit of skill at it!”
I looked at Kaijin. He responded by shaking his head. Guess we can’t rely on that too much. I pressed on, a little concerned for his safety.
“Well, I could set one up for you, if you’re sure you won’t regret it…?”
“Oh, absolutely! Besides, I have Sir Gabil to back me up. Oh, I do hope you could provide that!”
True. Having Gabil around probably meant no attacks were forthcoming. With those concentrated levels of magicules, too, normal monsters couldn’t even approach the place. Gabil and his team just barely got a pass, and even then, that’s thanks to the magicules dissipating a fair bit after I swallowed up Veldora. Humans and demi-humans had no issues, though, and the dwarves and hobgoblins could come and go freely, too. It seemed to me like natural-born monsters were more easily affected by magic, somehow. That seemed to explain it.
“Can I leave Vester in your hands, Gabil?”
“You certainly may! I am here, and I have two of my people on watch at all times!”
Gabil had certainly become a lot more reliable as of late. He got carried away far too easily, which worried me, but he certainly had skill. I could tell he was getting used to his new life here, and he and Vester seemed to hit it off. I thought I was safe leaving things to him.
So before I could work on developing potions, I wound up having to devise a home and laboratory for Vester.
I had both of them wrapped up in a few days.
It’s worth noting that Gabil and the other dragonewts slept immersed in water, so they didn’t really need living quarters to speak of. They could handle a bed just fine, but apparently the wings got in the way, so they were more comfortable underwater. Soka and the other females could fully put away their wings, so they slept in rooms, but I suppose even dragonewts had their own likes and dislikes.
For Gabil’s room, however, he had several of his men dig out what looked like a pretty comfy personal space for him. There was a ventilation duct and everything. He had brought in all the stuff he needed, and it sure didn’t look lacking at all to me.
Now we just needed a way for Vester to safely travel between here and town.
“Sir Rimuru, is it all right if I install a magic circle in here? Summoning magic’s going to be pretty rough on this side of the door, but it appears to be possible outside of it. I’d like to build one here, if possible.”
Vester’s chosen location was the spot where I defeated that first black snake way back when.
“What kind of magic circle do you mean?”
“A teleportation circle, sir. It would let me travel instantly to any location I associate it with. Activating it takes some time, but no more than a few minutes, so I think it would do wonders to reduce travel times…”
He was talking about a Warp Portal, a type of elemental magic. The caster made them work by drawing the same series of symbols at the entrance and exit. These symbols worked strictly as pairs, so stepping into a Portal would always bring you to the same destination, but linking this cave with someplace back in town would still be a great timesaver. Maybe Vester really did know a thing or two about magic. It came as a total surprise to Kaijin, who knew nothing about it.
The required symbols for a Warp Portal would normally be drawn with intricate, and expensive, magical potions. Here, however, we’d be using carvings made on magisteel—which technically was even more expensive, but it meant we could reuse them many times without having to draw them repeatedly. This, we could use to link up top-secret facilities within our own nation.
Elsewhere in the world, magisteel was too precious to last very long without being stolen. Carving-based Portals could only be built in areas where theft wasn’t a concern—leave one out in the open, and it’d face the full brunt of the elements, along with the potential for breakage or robbery.
We didn’t have to worry about cave monsters teleporting themselves into town with it, either. The user needed to exercise a few magical muscles to activate it, focusing on the destination in their mind.
It all sounded good to me, so I gave Vester the nod to go ahead. Magic teleporters, though, huh? Pretty useful. I’ll definitely need a primer on those soon.
Vester was proving to be a much more useful man than I had thought. Having total freedom to pursue his research made him a much less wily, treacherous fellow. He seemed to really love life now. And recalling my time in Dwargon, he didn’t seem particularly happy over there, constantly struggling for power. Research probably suited him more than ladder climbing. Having greed and envy rule your life, instead of the stuff you really want to do, would change anyone for the worse. It’s best to just do what you like, I think, as long as you aren’t bothering anyone.
So either way, we were all set to go, and before long, Gabil and Vester’s tandem research efforts were under way.
It had been a bit of a hectic time with King Gazel visiting and Vester joining my crew, but we were receiving quite a few other guests in the meantime, too.
Just as Treyni warned, the town was now playing host to a wide variety of races. The kobolds came first, stopping by in their usual trade caravan, and they must have been taken aback seeing al
l the massive changes to the forest. We were, after all, chopping down trees to procure more empty land to place buildings on, and once we wrapped that up, we kept ourselves busy widening the road to the lizardmen’s homelands around Lake Sisu.
“Wh-what is going on in here?!” one shouted at me. They knew something was changing near their own lands deeper in the forest, and now their finely honed nose for business had led them to brave the risks and check things out.
But the changes these kobolds experienced weren’t just to the scenery.
“Well, hello there, kobolds. I do so appreciate your business!”
“…Er, who may I be talking to?”
“Ha-ha-ha! It’s me. Rigurd!”
They need more of a hint than that, dude… And once we explained that Rigurd used to be chief elder of the goblin village, that made the kobolds yelp in surprise even more.
These kobolds, however, were pretty nice guys. The ones here spent their days wandering across the vast forest, covering their own sales territory, and one of them had been the main merchant handling Rigurd’s village. He was now talking cheerfully with several hobgoblins on the road.
“Would we be able to have your permission,” the kobolds asked me, “to build an inn and storehouse to serve as our base of operations?”
I gladly accepted the offer, and with that, I now had a kobold HQ in town, along with an entire clan of the guys to staff it. The old wandering-caravan days were over; instead, they used the town as a base to fan out and tackle all the other settlements they sold their wares to.
Some of our other visitors included halflings and merfolk. The halflings swore their allegiance to us, and I had them work on our farms. The merfolk, meanwhile, were seeking protection. They lived nearby a large lake that had recently become infested with a growing horde of amphibious monsters. I ordered Benimaru to send a cleanup force their way. Most of the trade between us and the Dwarven Kingdom would involve traveling along riversides, and I was sure the merfolk could provide some assistance with that. If they were willing to work with us, they were more than welcome.
As far as more uncommon visitors go, one time, while exploring in the woods, I came across an insectoid—an insect-type monster—that was near death. It was maybe a foot and a half tall, kind of a cross between a stag beetle and one of those big fighting ones, and I just thought it looked so cool. There was a dead blade tiger next to it, a B-ranked monster, and imagining this small creature defeating such a formidable foe was remarkable to me.
So I decided to take care of it. It was hostile at first, attacking me without a moment of hesitation. That seemed reckless, but I quickly realized the motivation. There was another insectoid behind it—it had attacked me so the other one could make its escape.
I didn’t notice the other guy until it spoke up. “W-wait,” it pleaded. This one was about a foot tall and looked like a garden-variety wasp. A foot-long wasp would be the subject of horror films in my world, but this one, too, was critically injured. It was intelligent enough, at least, to communicate with me via thought, albeit haltingly.
“…Why do you not flee? I have no way left to protect you. Forgive me,” the insectoid who attacked me muttered, resigned to its fate.
The other guy must’ve been pretty smart, too. And even though the blade tiger almost killed it, it was using whatever strength remained to confront me. It seemed to be choosing to die a noble death, perhaps realizing that the time was near.
“Strong one,” the wasp asked me, “you…protect us?”
I couldn’t find it in me to just abandon them. Something about that beetle doing whatever it could, even near death, to protect its friend struck a chord. No reason why they couldn’t join the party—
Then an idea hit me.
“Hey, can you guys collect nectar or whatever?”
“Yes… Can.”
I figured they might be able to collect nectar from flowers, and they could. That provided all the reason I needed to lend them a helping hand. They both had lost around half of their bodies, so I lent them a few cells from my own slime form to treat them, using processed magisteel to replace the missing parts of their exoskeletons. That, plus a dose of healing potion, fixed them right up. I named the cool-looking beetle Zegion and the wasp Apito, and now they were my subjects, or pets, or something.
The rarer plants I collected in the forest included those that would only bloom in special environments or places laden with magicules. Apparently such flowers bloomed readily in the treants’ settlement, however. I figured Apito, with its intelligence, could scope out those rarities for me and provide the nectar from them.
Treyni was kind enough to give permission for this, so I ordered Zegion to keep the treants safe while Apito collected the treasure. It would then deliver the nectar spoils to me on regular occasions.
So along those lines, we were starting to find more and more friendly people to interact with. But they weren’t all friendly. Sometimes we’d get small gangs of lower-level magic-born sniffling around and spouting out classic hoodlum clichés like “Whoo, ha-ha! What a fancy-lookin’ town this is! We’re gonna treat it reeeeal good from now on!”
Gobta’s or Rigur’s patrol teams were usually all it took to chase them off, but we’d occasionally run into monsters with some actual strength as well. Such lower-level species always met a tragic end before long.
“Oh, uh, Shion? We’ve got some guests.”
“Yes, Sir Rimuru!”
The idea of talking things out never registered in Shion’s mind. She was much more a fan of duking things out. Really more of a bodyguard than a secretary, and she was harsher on her opponents than Gobta or Rigur ever were.
It was the same thing every time, really—no matter how many lower-level magic-born gathered together, there was just no beating Shion. And when they were sniveling on the ground, begging for forgiveness, only then would Shion smile and ask “So how can I help you?” Even the most arrogant of them would never be seen in town again after that—and if they did, Shion wasn’t keen on second chances.
Generally, I asked her to avoid killing if she was able to. Monsters were all about survival of the fittest, and a convincing show of strength would usually be enough to force them into obedience. Any wayward souls who couldn’t listen to reason and decided to be naughty a second or third time, though? Yeah, I gave her permission to execute them. I didn’t have time for monsters who couldn’t show regret for their actions.
There were still a lot of folks out there who looked down on me for being a slime, weakest of all monsters. That, or called me soft for not killing my foes, no matter how much they dissed me. But I figured those stories would disappear pretty fast, in time.
Soei, in particular, was even colder and more calculating than Shion; he tended to expel any would-be attackers only after introducing them to the meaning of fear. He told me he was busy building up a defense network for the town, but I think he was also doling out punishments for anyone who thought they could do whatever they wanted with us.
At the moment, the forest’s native races were most likely testing us, trying to see what this new force in Jura could do. That’s why we were kind of obligated to puff out our chests a bit, so we could get everyone else to recognize us. We’ll gradually roll that out, and slowly but surely, we’ll make ourselves known.
So the city of Rimuru, in the heart of the Jura-Tempest Federation, was doing a pretty roaring business…but then we encountered a guest we weren’t expecting at all. My Magic Sense alerted me to a massive chunk of magic power flying our way—at a speed I could only call ridiculous.
Oh, crap! In an instant, I jumped off Shion’s chest and headed outside the gate at a full clip. I was right to be concerned. The magic force changed its aerial trajectory and landed right in front of me. If it had gone inside town, I think we would’ve seen some substantial building damage. The nearby trees had been uprooted and blown away, and there was a crater on the ground where it landed.
I insti
nctively realized there was no way I could handle this level of force. Steeling my resolve, I decided to observe my opponent. Just one look was enough to see that this was on a completely different dimension from anything I knew.
A powerful will hid behind her blue eyes, and her platinum-pink hair was done up in a pair of pigtails. She looked around fourteen or fifteen, but there was no telling a magic-born’s age from external appearances—and with the overwhelming amount of magical power that she didn’t bother to hide, she couldn’t have been the age she seemed to be. She was wearing an outfit that left quite a bit of skin exposed, made out of some unknown material. And—more than anything—she was a beauty, the likes of which I may never have seen before.
Before I could ask who she was, she arrogantly puffed out her chest (her breasts only barely developed). “Hello, hello! I am the demon lord Milim Nava. You look like the strongest hombre in town, so I wanted to come ’n’ say hi!” the beautiful and powerful girl declared.
A few minutes before, Milim the demon lord had spotted the town below her. It was a pretty place—neatly organized rows of buildings, attractive trees lining the city roads. It was a town that seemed to exist in perfect harmony with nature, and she could tell that several high-level magic-born, rated A or higher, lived there.
The biggest surprise of all, however, was that even the rank-and-file residents of town were at least low-level magic-born people as well. Their magic potential varied, but they were all creatures with intelligence, thinking for themselves and carrying out the work assigned to them.
Nothing like these people existed in the Forest of Jura before this point. Seeing such a settlement appear practically overnight would normally be unthinkable. They were all working together, regardless of their differences in strength. Milim couldn’t even imagine what kind of leadership skills were required to make them all follow that.
