Chapter 10: [Crimson Cavern]

“Are those your subordinate monsters?”


Marcho, with a stiff smile on her face, said so to me.


“Aren’t they precious?”


Tenko and I had raised our levels until the recommended level of 10. Succubus then transferred us and we met with Marcho.

Naturally, it was for the sake of being guided to the [Crimson Cavern].

The Skeleton squad would also be taken along. Each of them carried an M&K MK416 assault rifle and it was a spectacle.

The combination of the emotionless Skeletons and their boorish guns gave quite the atmosphere.


“This is the first time for me to see a Demon Lord really make use of something like a Skeleton.”

“If it’s me that uses them, even Skeletons would be a splendid force in battle.”

“That’s certainly true. It may not even matter who uses that weapon. You’ve thought about it well.”


In an instant, Marcho had seen through my plans. As expected of a skilled Demon Lord.


“Procell, one Tenko, and nine Skeletons. Well, somehow you’ve managed to have ten monsters, a full party. For a newly born Demon Lord, that’s a considerable battle potential. Like this, I’ll have some peace of mind and be able to send you out. However, I’ll say it again, do not get careless out there.”

“But of course.”


I had no intention to venture deep this time. I did want to someday break the crystal and have the ability to create its owner’s original medal but as one would expect with my still incomplete fighting force, I wasn’t able to do so yet.

Only after I had three [Monsters of the Covenant] and get them to level 50 would I plan to conduct a full-scale conquest of that place. Until then, I shall focus on leveling up and earning DP on the early floors which I could always return to at any time.


“Well, you are prudent and smart, so you probably won’t do anything rash. Just to be safe though, I’ll lend you Succubus. Succubus, I ask that you look after him.”

“Is that alright? If I’m not around, the monsters from the residential area won’t be able to transfer anywhere.”

“It’s fine. Rama has to be put to work once in a while.”

“I’ll be relieved if Rama-sama did work.”


It’s likely that Rama isn’t a race’s name but rather a given name. If Marcho went so far as to name it, it was probably a very powerful monster.


“Well then Succubus, look after him. And although I asked you to help him out, if ever there came a situation that you are forced to choose between your life and his, choose to protect your own. To create a situation wherein he’s driven to a corner like that, Procell has nothing else to blame but his own foolishness. You need not hesitate about it.”


She said some severe things but they were reasonable.

To start with, just lending Succubus was very generous of her. A B rank monster was a valuable asset.


“Certainly, Marchosias-sama! Well then, we’ll be heading out.”

“Yeah, take care.”


The conversation between the master and her follower concluded.

Succubus then deployed a magic array.


“Wait a moment. Succubus’s magic can be used to transfer us even outside the Dungeon?”


Succubus was concentrating on deploying the magic so instead of her, Marcho opened her mouth to answer my question.


“If there’s a magic array prepared beforehand, then yes. Transferring from one array to another is an application of the magic of a Succubus, a monster that slips in into dreams. However, she can only bring along with her a maximum of two people.”


What a convenient ability.

In the future, if ever I got ahold of a medal that can make a Succubus, I would definitely want to make one.

The Lich that controls the undead and the Succubus that could use transfer magic. The monsters that I wanted to make were rapidly increasing.


“[Creation] Demon Lord Procell-sama, the preparations are complete. We may leave at any time.”

“Understood. Let’s go immediately.”


I stored away the Skeletons and the two of us, Tenko and I, moved close to Succubus.

And then, blue light filled the magic array that Succubus had called forth.


“Ah! Procell, I forgot to tell you something important. Very soon, all the Demon Lords will assemble………”


Marcho spoke halfway through the transfer magic. While I worried about her news, my body was wrapped around in light. And so, for the first time since I was born, I went outside of Marcho’s Dungeon.



“So hot.”


Such were the first words I uttered upon arrival.

This place was humid. As one would imagine from its name, the [Crimson Cavern] featured pretty high temperatures. Rather than being in a cave, one would have the impression as though they were inside a volcano. All around us was earth and stones, illuminated by the brightness of the flames. The path ahead was wide, probably more than three meters wide.

I immediately deployed the Skeletons. They made clattering sounds as they formed a line.


“Oto-san, do you feel hot?”

“How about you? Do you feel alright?”

“Tenko feels fiiiinne.”


For Tenko who ruled over fire, this much heat seemed like it was no trouble at all.


“It’s hot for me too so I don’t really like going here.”


The Succubus similarly felt hot.

And although she was always lightly dressed even under normal circumstances, her eye catching way of pulling the hem of her clothes allowed me to see various things I shouldn’t have.


Incidentally, the Skeleton squad did nothing but rattle their bones. I had no idea what exactly they were thinking about.


“If you both feel hot, then Tenko will cool it down.”


Just as she said, the temperature of our surrounding dropped.


“Is this Tenko’s magic?”

“It is! Does Oto-san feel better?”

“Yeah. It’s cooler and feels much better now. It helps a lot.”


Tenko had the skill called Ruler of the Flame.

Its effects were that it gave the flame attributed magic spells maximum power ups while also decreasing its consumption of magic power. Not to mention that it also allowed its user to control all flames within their vicinity.

The true nature of Flame magic was that it manipulated of the amount of heat of its target and thus it was also very much capable to lower the amount of heat it had.

If things went on to be this pleasant, we would then be able to hunt in good spirits.


“This is to express my gratitude.”


I used Creation to make a caramel.

Upon doing so, Tenko opened up her mouth wide so I threw it in there.


“Yay! ♪”

Tenko who had been getting addicted to caramel lately looked happy as she tasted it.


“There’s one thing prior I’d like to tell you.”


Succubus halted our departure. And then, she pointed under our feet.


“My transfer magic, when used outside of Marchosias-sama’s Dungeon, only allows me to jump from one array to the next. In others words, if we wished to return to Marchosias-sama’s Dungeon right away, we have to go all the way back to the array which is engraved in this place. So I hope you take note of our exact path.”

“I understand. I’ll pay attention to it.”


It probably was possible to exit the Dungeon normally but not using transfer and instead walking all the way back to Marcho’s Dungeon was a thought I didn’t want to entertain.

So I used [Creation] and created a transmitter. Furthermore, I also used [Creation] to make a receiver and a smartphone. I then installed the receiver on the smartphone.

There wasn’t any GPS so producing a map was impossible but if I were to use an app, I would at least know the directions.


For the moment, I tucked the smartphone in my breast pocket. The record function was turned on. It might come in handy in the worst case scenario.


I remembered each and every kind of gun there was and was even able to prepare this kind of thing but just what the heck kind of person was I?

The mystery only deepened.

I probably wasn’t a decent guy.


“Succubus, is there anything else?”

“Nothing more from me.”

“Well then, let’s go.”

“Yay ♪! Let’s kill lots!”


All our preparations were complete. We headed out for real this time.

    I’m really late in asking this so probably there’ll be no one who’s gonna reply to this, but I just wanna ask something

    In novel update, I see that there are two novel that shared the same universe as this one. Incidentally, one of those is the novel that is advertised in this chapter

    What I wanna know is that if those mc from novel that are in the same universe, will they meet each other directly or indirectly or maybe only mentioned as legends?

    Cause I know that there are novels that are connected by the same universe, and if you want to completely understand one of those novels that share the same universe, you’ll need to read the other novels that share the same universe

    So I wanna know whether this novel has some kind of influence to the other novel in the same universe or vice versa and what kind of influence did it have

    • Hi, I’m the translator for this one. I haven’t read the others, so my answer isn’t conclusive. But from what I’ve seen, the other works are mentioned only as advertisements. No real interactions between works. Nothing significant at the very least.

    The first monster he created can freely manipulate heat (energy stored in particles). I’m guessing the next two will be able to manipulate matter and gravity respectively 🙂


  3. Thanks for doing this chapter!😇


  4. Anyone interested, here’s the link to the author’s other web-novel on novel-updates.


  5. I’m kinda back? Dunno. Hello! 😀

    “Just as she said, the temperature of our surrounding dropped.” -> “…, the temperature of our surroundings dropped.”
    “The true nature of Flame magic was that it manipulated of the amount of heat of its target…” -> “The true nature of Flame magic was that it manipulates the amount of heat(/temperature?) of the/its target…”

    “I remembered each and every kind of gun there was and was even able to prepare this kind of thing but just what the heck kind of person was I?”

    As expected, he is probably the cliché assassin or gun otaku in his previous life… Well, i know that author don’t have so many choices if he wants MC to create and use guns in another world but still..


  7. So I used [Creation] and created a transmitter. Furthermore, I also used [Creation] to make a receiver and a smartphone. I then installed the receiver on the smartphone.
    There wasn’t any GPS so producing a map was impossible but if I were to use an app, I would at least know the directions.

    I’d like to think that making stuff like this would require him to know EXACTLY how a smartphone and transmitter/receiver works and what kind would work with that model of a smartphone. I mean, he’d have to know every circuit and part of the phone, like the cpu, screen and other things, not just that it requires something like that but rather EXACTLY how that one part in this thing works, how to make it by himself from scratch. I find that unbelievable, but I guess the author can still justify it somehow(even though it’s just about impossible, especially if we consider he’d have to remember everything correctly, every small detail, not even the creators can do something like that). Otherwise he’s able to create stuff just by imagining what it is, that’s just unbelievable since it is a skill that uses his memory to make something… Ah, I guess I can’t even apply such common sense to this novel :/ It’s frustrating.


  8. I have a feeling abut gun no ota novel here…thanks


  9. Yay! ♪… I’m done here.

    Hmmmm…. the author’s new novel sounds like this one


  11. I wonder if by leveling up those squeletons can evolve into something more…..usefull


    • I doubt there would be evolving in this novel. My reason is that there’s the option to either make your monster have static levels or one where they could grow. I mean, if a monster can evolve, the option to let them level up would almost always be selected, right? Even for the weak monsters

        I know this comment is over 2 years old, but just wanted to point out something. First of all it has been pointed out in the novel already that other than ones that a Demon Lord wants to create a sort of relationship with, they choose a static level. The demon/creature will start off higher level than allowing them to grow. Skeletons for example, being one of the weakest will be anywhere from level 1 – 10. because they are so weak other demon lords don’t even bother.

        However, if you give them the ability to grow they will always start at level 1 and their maximum level they can attain is higher than the maximum level that can be randomly generated, for example with said skeletons they can go up to 20. Since a Demon Lord would have to make sure that every creature they created with growth would have to be trained, most don’t bother. That’s why I think that the skeletons the MC created may show something that isn’t expected. After all, no Demon Lord uses them and he is planning on growing them to their maximum potential as at level 20.

        There isn’t much shown about the effects of leveling have had on the MC’s stats as well as that of Tenko. So who knows, he might end up with some really powerful skeletons that could take on C rank monsters even if they are G rank. Of course I’m not taking into account the modern weaponry that he has equipped them with. They might be able, as they grow, to slowly work their way up in mastery and being up to be given much more complex commands and taking more complicated actions.

        The other thing pointed out, so far, is that the MC has memories of his previous world and that, of course could be something unique about him. What we may see as common sense, allowing monsters to grow to reach maximum potential, may not be the common sense of the world. They are Demon Lords. When they are capable of making their own dungeon’s they may want to rush to start gathering DP as much as possible. Static levels would be much more convenient for that than allowing growth.

  12. Well… may be he will make some nuke too…


  13. So Succubus, I’m thinking either an IMI Desert Eagle and Lich I see an M40 sniper rifle, leading the unread from range and cover shouldn’t be an issue.


  14. Thanks for the chapter :3

    Are you joking? Knowing about every strength and weakness about weapons would be a huge boon to whoever goes against a user of said weapons. ( soldier, police, assassins, mercenaries, even robbers would benefit )
    Besides not being a decent guy does not mean only being a stalker, he could very well have been a mercenary working for some private company, or an arms dealer, an army veteran who went crazy and murdered people left and right. Or he could have simply worked in the weapon’s manufactoring sector for all we know.

  15. Im quite curious as to why exactly he wouldn’t be a decent guy even if he knows in detail about guns and a transmitter / receiver , most likely an otaku of some sort but also could be an engineer , a soldier would have no requirement for knowing the intricacies of every gun but a special agent could also be possible . A stalker would have no use for a gun or a way to map in unknown places .

    I’m going to go ahead and hazard a guess that a named Succubus is going to eventually become another member of his harem. Mainly for her transportation capabilities of course; but I’m sure some private transfer of mana may be in the works too.
