My smartphone alarm rang loudly.

As usual, I sat up and started getting ready for work...

"Ah, right. I came to another world... Seriously?"

Apparently, the cliché where you wake up and find out it was all a normal day didn't happen.

In fact, I started wondering: am I actually asleep or in a psychiatric hospital right now, and this whole "other world" thing isn't real...? But even if I'm inside a dream or a delusion, I have no intention of going on a rampage. I have my own ethics and pride.

Well, enough with the escapism. Let's get down to the business of running this dungeon.

That said, the only thing I can really do right now is strengthen my subordinates—the goblins and green slimes—mainly by teaching them tactics.

Unfortunately, this isn't some generous system where DP replenishes just because a day passes. Anything produced inside the dungeon, or by my subordinates, doesn't get converted into DP either.

So how do I earn DP?

Apparently, the dungeon's purpose is to circulate magical power. In other words, the amount of magic brought in from outside gets converted into DP.

Yes, from the outside.

This means that even if the MP of my subordinates leaks out and circulates through the dungeon, it just gets canceled out by their maintenance costs.

In extreme cases, if they have massive MP, I could reportedly inject it into the Dungeon Core to convert it, but personally, I'm not a fan of that. I'm not about to convert my own MP—which could be my lifeline in a life-or-death situation—into DP.

On top of that, as a kind of balancing measure, converting MP into DP through a dungeon core only yields one-tenth of the value. With my current max MP of 690, even if I dumped all of it, I'd only get 69 DP. That's barely worth it. Maybe if I were holed up for a year with no visitors, I'd consider it.

First, the most efficient method—luring enemies into the dungeon and killing them. Their HP + MP gets converted into DP. I haven't actually killed anything yet, so I can't confirm it firsthand. Even if it's written in the tutorial, I'm not the type to trust it without data.

Second, making enemies use MP. If they cast magic, their MP disperses into the dungeon and gets converted into DP.

And lastly, the least efficient but potentially the most stable method over time:

If living beings stay in the dungeon for over an hour, their MP is naturally absorbed and converted to DP.

The conversion efficiency is 1 DP per hour. Powerful mages or heroes might leak more MP unconsciously, raising the rate, but generally, it's 1.

My long-term plan is to gather humans, build a town inside the dungeon, and farm DP semi-permanently. But that's a distant dream. Dungeons are currently seen as gateways to death, so getting people to live in one is a tall order. Wild animals are an option, but they're not very reliable.

So, back to the main point.

Right now, I need to build a fighting force capable of defeating intruders and generating DP.

According to Luna, the goblins and slimes I have are already unusually strong.

She said it might be because I'm from Earth, but honestly, that doesn't reassure me at all.

No matter how strong they are for their species, they won't be beating a level 100 enemy. Personally, I'd only feel safe if I had monsters strong enough to casually beat heroes or demon lords.

In light novels and manga, having stronger-than-average monsters as allies usually means you've got reliable companions.

But only within those stories.

So I decided to train my goblins and slimes using the ultimate weapon — the internet.

"Listen up! From now on, I am going to train you! This is training to strike down the enemy, but in truth, it is more than that. The real goal is to surpass your current selves! You don't understand? No, with your intelligence, you should! In the end, the one you are always fighting is yourself. If you can defeat an opponent tomorrow that you couldn't defeat today, it doesn't mean you beat them—it means you beat the 'you' of yesterday who couldn't win! Do not be arrogant. Learn, and grow stronger, so you do not lose to your past self!"

I gave them a random speech, and while I couldn't tell if they truly understood, I laid out the special training regimen.

"First, you will form 5-man teams. We will designate Squad Leaders and Assistant Squad Leaders. You will learn Small Unit Tactics... CQB: Close Quarters Battle!"

We don't have firearms, but this is still highly significant. The gap between the coordination of a medieval-level civilization and our proud modern combat tactics is massive—both technically and mentally.

By the way, for those worried that teaching human tactics to goblins might be pointless—don't worry.

I posted on a forum asking how to adapt CQB tactics for goblins and slimes, and got everything from ridiculous ideas to genuinely effective strategies. Comparing a modern online forum full of knowledgeable people to medieval-level information exchange is pointless.

But training alone isn't enough. They need theory too. So I began explaining the dungeon structure alongside their drills.

First Floor

A classic maze. A stone-built dungeon. Here, they'll use traps and slime ambush tactics through narrow passages—perfect for indoor CQB combat.

Second Floor

A battlefield using grasslands and forest. Use everything in the environment, create traps as needed, and confuse the enemy.

Third Floor

The final defensive line—my personal room is here, along with the dungeon cores. Use that to corner enemies and teach them that carelessness is the greatest enemy.

I trained the goblins and green slimes as much as I could.

The result—

Their Intelligence and Luck only went up slightly, but the other stats are insane. I mean, even I think this is abnormal. Did I overdo it? Maybe these two were just special cases.

"Whoa—!? Wait, come to think of it, aren't sergeant majors usually the veterans who handle training!?"
