Reincarnated as a Dungeon Master, I Became Unstoppable by Doting on My Monsters—My Gorgeous Monsters Have Started to Conquer the World on Their Own!

I slowly opened my eyes.

I’ve confirmed that my consciousness has been transferred from the Pilgrim. Even as material for creating thieves, the scenery outside can be seen without issue, so the enemy’s information is fine.

After confirming that I was fully awake, I returned my face to my own.

Next, I quickly adjusted my body. I’ve borrowed the Pilgrim skill several times in the past, so I’m used to it.

The leg is definitely Egrentine’s, but the chest is Clarymond’s.

I am maintaining a feminine body for my master’s sake, but that said, I do not have many uses for breasts in battle, and I have determined that the disadvantages outweigh them.

…I look at the door to the boss room and think.

(This will be our first crusade.)

Remembering my master’s fearless face, I let out a sigh of relief. My previous battle with Onibird in the forest was a rehearsal, so to speak, for me to chew through my master’s teachings.

But this time is different. When Yuuto-sama conquers the world, her goal is to occupy the Dungeon that serves as its first stronghold.

In other words, a conflict for the expansion of territory. A conflict for the expansion of territory for the master of heaven. How can we call this a crusade?

…Many other Nanaya shrine maidens recognize the kindness, the depth of their love, and the breadth of their insight as the magnificence of their master.

However, I believe that the fact that my master has never lost in ten years of dungeon management is also necessary to understand the greatness of it

In that forest, where he’s always at a higher level, his master has fought well over a hundred defensive battles. He may have lost to Jacqueline, but it’s a necessary loss to grasp his connection to her, so he’s effectively undefeated.

We’re not dead.

The other shrine maidens aren’t that impressed by their master’s victory, since it’s only natural for a master not to lose to a small fry. However, it’s not easy to continue to win in a duel where your lives depend on each other.

And the many combat techniques Master Whit has cultivated on Earth. As the greatest disciple of the master who inherits them, defeat is not an option for me.

I pray while thinking of my master so that the soldiers can visit the shrine before the war.

Then I steeled myself and opened the door.

As soon as I open the heavy door to the boss room, I check the situation.

(Master’s teachings. The order in which you confirm is always your own mind technique body. The mind technique body of the place. Finally, the order of the opponent’s mind technique body.)

First of all, as always, my heart is free of tension and excitement.

The technique is Pillit-san’s skill, and there are more of them than usual, so it’s tuned and clear.

You’re in good shape, too.

The problem is the emotional state of the room. The mind certainly has the atmosphere of a decisive battle, like a boss room.

However, the technique is terrible. Despite being the boss room’s habit, we’ve been able to confirm traps all over the place. Iron thorns, electrical currents, and hot water, respectively.

The body of the field… It-It was underwater in the first place, and there seemed to be violent currents swirling around it all the time.

Finally, I look at the opponent’s mind, technique, and body.

The boss in the back was a group of five killer whales. …If there are multiple enemies in the boss room, that means they have skills like that.

Master confirmed that only if that strength includes the fact that they are a group can there be more than one enemy in the boss room.

First, I look at the enemy’s heart. It’s hard to read the killer whale’s mind from its face, but its appearance is far from that of a master on the battlefield. In other words, it’s incorrect.

…The technique is no good, either. It’s a form that relies on the physical abilities of beasts.

His body really is well-formed, isn’t it? In the first place, monsters on standby in the Dungeon can heal their wounds by committing suicide, so there’s no way your body can’t.

My master taught me how to use different martial arts to match each individual’s mind and body. That said, the body of the field… With the environment in such disarray, I’ll not be able to use any good martial arts.

However, there is something you can learn by observing the enemy and their location beforehand.

The orca is swimming calmly in the violent currents. …The currents have physical strength, so they can’t stay calm.

Even if you have the superhuman strength to lift boulders, violent currents are abducting your body with an unbelievable amount of mass.

And magic to prevent that doesn’t exist while it’s within the Dungeon Master’s authority.

In other words, it was confirmed that one of the opponent’s race skills was something like Current Nullification. On top of that, being in the Boss Room in a group means that one of the race skills is guaranteed to have “Skills related to the herd.”

At this point, we were able to pinpoint two species skills that should only have a limited number of them.

-Does the other party not know about the information advantage?

The enemy ranks in a dungeon of this scale are probably C or B. I think splitting two out of five or six race skills would greatly reduce our chances of victory…

In the first place, while the enemy can’t leave the Boss Room, standing by in a place they can see from the outside is ridiculous. Sure, there’s the advantage of being able to see us from the other side, but this is the enemy’s base, so we should be able to share information.

…According to the pilgrim, he’s a director, but he’s always the one who hasn’t found an advantage in the battlefield.

Beauty on the battlefield comes from a stance that doesn’t allow you to predict victory. As a director, you can’t call yourself a Dungeon Master if you’re wrong about that.

Well, let’s get going. We’ve already come up with a plan to win to some extent.

Watch the currents from the outside, and find the waves you want to ride.

(Oh, here it is.)

We’ve found the current we’re looking for, so we’ll jump right in.

The moment you enter the Boss Room, you will be instantly abducted by the current. Not only will you not be able to move your body, but you won’t be able to move a finger properly due to the force of the water.

And then, cruelly, at the end of the current I rode was an iron thorn. The enemy watched me drift into the pitiful boss room and surround me.

However, I didn’t try to straighten my posture. Instead, I extended Egrentine’s tentacles toward the iron thorns.

Egrentine’s Tentacle Skill is such a useful skill that if she’d been more eager to fight, Nanaya’s Priestess’s battle ranking would have changed.

…One of the techniques my master taught me, the art of capture, is to tie my body together with a tentacle, then stick the tip of the tentacle into an iron thorn and crucify it.

By having the Iron Thorns pierce my tentacles like this, I was able to prepare myself for battle. Pain runs through my painful tentacles, but it’s not unbearable.

After I slammed into the wall, the killer whale seemed intent on poking and playing like an aquarium show, but when it saw me completely settled against the wall, it realized I wasn’t human.

“He’s not human, is he? Finally, the one that looks like it’ll last a long time! Yay! It’s been a while since I’ve eaten. I have to play! I have to play so I don’t die!”

The killer whale let out a cry of joy. He was able to talk, wasn’t he?

…………But they’re so excited. I can’t bear to watch them pity me, so I quickly narrow my eyes.

They’ve probably been trapped in this small boss room for over fifty years.

They have no intention of fighting. They just don’t want to waste time. That’s why they let their guard down, and why they’re so happy when their boss is in danger.

But as a warrior, I’m grateful for this new information. After all, I’ve learned that these aren’t unique monsters.

…Rank up to Unique Monsters requires a will of her own. Dreaming won’t get her out of the Boss Room, so there’s no way she’ll have a will of her own.

-Miss Jacqueline said that doting on monsters wouldn’t have any effect, but I don’t think there’s any way an intelligent monster would be able to stay in a closed room called a boss room like this.

Well, that doesn’t mean my master is too kind.

(…If we’re going to have subordinates in the Dungeon from now on, we’ll need to create a space where those kids can get along… Just like my master did.)

“First, eat through that tentacle that’s serving as your lifeline.”

A particularly large killer whale said, “The operation is leaking out here. You don’t seem to realize that I can hear the language of the sea through my master’s grace.”

For the time being, it seems the opponent will bite the tentacles that they can make as many as they want, so I’ll leave it to you.

The four killer whales are closing in on me with their huge bodies. The only one who talks is that rugged one, but each of them seems to agree with my plan to kill me after bullying me. They look like they’re having a lot of fun.

The moment they bite off the tentacles, I concentrate their power and feel it. …B+, or B, right? They have high intelligence, and they look sturdy, so they’ll probably call this a B-Rank monster.

If you’re just calculating the rank, that means there are five opponents that we D-Ranks can’t match, even if there are a hundred of us.

But that’s just a difference that can be easily overturned with my master’s teachings.

(My master’s teachings. If I’m surrounded by something overwhelmingly strong, I don’t expect kindness, I don’t expect victory, and I think about running away.)

However, there is no escape route in the Boss Room. Therefore, let’s fight with our backs to the wall.

I reach out with my tentacles again and stab them into the thorns. It hurts a lot, but it’s nothing if you’re prepared.

(Master’s teachings. If you don’t have a chance, run. Even if you do have a chance, think of another way to win.)

In any case, my master’s teachings are all about survival. As long as you’re alive, you can win. That’s the basic principle.

More than anything, the currents are dangerous, so there aren’t that many strategies we can use. To think that a head-on battle with a higher rank is not allowed.

“I’d be more grateful if you didn’t die in a trap.”

Well, they’re licking this way too, so this is a simple case.

What’s more, I can tell that the four of them are on cloud nine as they listen to orders.

…Ever since I started following my master’s teachings, I’ve never lost a battle.

I’ve never found anything interesting in combat, but every time I put my master’s teachings into practice and beat the enemy, I get closer to him.

This is why I like fighting. It’s not like fighting itself is fun.

“Now, bite your arms and legs and tear them off.”

Responding to her voice, the four rapidly accelerated killer whales dug into their arms and legs.

They must have been expecting me to suffer, because they bit off my limbs while shaking their heads and tearing me off with their mouths.

…I didn’t intend to lose, but I didn’t think it would come down to the first plan.

“Hold on! I didn’t give you any instructions like that!”

A particularly large commander like Shachi would say something like that, but it’s too late.

「It’s my teacher’s teaching. The last thing that decides a battle is your acting ability. Sorry, Clarymond.」

I transformed my arms and legs into Clarymond’s the moment I was eaten.

If I disarm the thief creation now, Clarymond will be the only one to return to her missing limbs, but I’m sure she’s prepared for something like this the moment she came up with the thief creation plan.

…Killing the higher-ranked ones who ate her was her specialty. It was the same plan her master had during her first battle in Etina.

There’s a difference in rank between that huge cow and the killer whale this time, so even if you try to hold your breath, you’ll probably live a long life, but Clarymond is an amorphous person. He can even imbue an arm with a bomb.

The next moment, blood gushed from the body of the killer whale that ate its limbs, and no sooner had it relaxed than it was swept away by the current.

…Your life must have ended.

The explosives embedded in Clarymond’s limbs were designed to kill monsters created by the Pilgrim.

Air holes, rosin… Pine root oil, the oil from the pines, turned into powder, and a simple bomb made from the alcohol Jacqueline gave me. If you’re in the forest and you have alcohol, all that’s left is a bomb you can make with processing technology.

However, it is powerful enough to circulate poison through the body in one fell shard.

Clarymond’s corrosive bodily fluids must have mixed in with the blood. They were poisoned from the brain to the organs and died.

「First, there are four of us.」

Just in case, I’ll check the field to see if there are any skills that will activate after death, but it doesn’t look like there’s any more problems.

“C-Curse you. You even had a skill that imitated voices.”

The killer whale sounded pained.

…We won’t be able to escape inside the boss room, but we won’t be able to call for backup either.

Still, there’s no way a skill that mimics a voice could be such a stupid skill. My Unique Skill is my teacher’s training itself.

“Legendaryization”. That’s a physical technique that 22-year-old men can do if they work hard. It’s a skill that most of them can learn without practicing.

It’s not like I enjoy training or getting stronger. I can’t catch up to my master unless I can skip practice.

In that sense, you could say it’s the kind of skill that exists for me when I’m trying to assimilate with my master and spread its magnificence throughout the world.

…Well, I’m not obligated to tell you.

“But this is the end!!! If only I had my Sonic Wave Cannon!!!! A-Agah?”

The orca, who was acting all high and mighty, stopped talking. It was a symptom of the electric current that caused the muscles in his mouth to stop functioning properly.

Unable to bear it, the killer whale writhes in agony and tries to escape. During that time, I use [Hardening] to avoid the current.

「It’s troubling, but my teacher’s teaching is that you must never lose in a match.」

Honestly, I wanted to try putting my master’s teachings into practice a little more, but… As soon as the preparations are complete, the opponent starts to cum, so this is probably a match time.

I can feel a burning sensation from the tentacles. It’s the heat of the electric trap’s scream.

-While I was fighting, I used my tentacles to make the traps in the boss room a part of my body.

Honestly, it’s a skill that allows you to move those parts of yourself if you embed a machine after severing your body, but with enough time, you can also manipulate electrical traps.

…Of course, it’s an act that requires delicate manipulation and practice, but that kind of movement is easy to perform if it’s ‘legendary.’

I poured electricity into the trap until it shorted, then thought to myself as I watched the boss room open.

(But this battle was a bit like my master’s. Like sacrificing your own body.)

Satisfied with that rather than the results of the battle, I made my way to the Core Room.
