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!

“Hmm, hmm. Looks like we don’t have enough information to know that the iron stakes of Dernata will work!”

The Pilgrim reached the area around the large lake in the island’s center. The surrounding area was still covered in tall trees, but the sun shone down on the lake’s surface.

Technically, that hole was filled with seawater, which was an entrance to the undersea Dungeon.

The pilgrim inserted a small iron stake into the ground around it, watching her excitedly.

…The stake, called the iron stake of Dernata, is a device that grasps the inside construction from outside the Dungeon. It’s the one that used the Labyrinth of Ragnel in Jacqueline before.

The pilgrim’s eyes were shining with interest in dungeon renovations due to the structural information they’d get from that.

These items began circulating in the market ten years ago after the War of Deputies by the gods began. Stakes are a prime example.

The advent of such items was one of the factors that led to the start of the golden age of hunters.

Some lesser gods participating in the proxy war create items for hunters day in and day out in hopes that the other dungeons will be easily crushed. That means that the god called Dernata was one of them.

“Heh, heh. You may be an old soldier, Lottor, but you still have a long way to go if you haven’t figured out how to deal with the items that came out five years ago!”

With a cool, nihilistic smile, the Pilgrim quickly completed the Dungeon Map.

The newly formed dungeons over the past ten years probably have countermeasures against such items, but the dungeons that have been around for a long time still haven’t caught up to countermeasures… Many of them don’t know about such things because there are no intruders in the first place.

And this Dungeon, the ruler of Grabsdred Island, could also be said to be one of those dungeons’ companions.

The Pilgrim identified what she could read from the Dungeon Map she’d drawn next, then wrote down countermeasures for it.

“Other than that, it’s easy to see the passage. I thought it was standard practice to hide it.”

—-The rules of the Dungeon have a very rough authority: You can’t place things in an impossible position.”

It was quite coercive, and Yuuto had tried it several times, but all loopholes, such as making the passage extremely narrow, had also been crushed.

It wasn’t like there were any specific rules, but as if reading the Dungeon Master’s consciousness, countermeasures could be taken from when he cheated.

…You could say it’s the result of Lady Nanaya’s brazenness and shrewdness having a positive effect.

“Well, you have to have a body that can withstand the deep sea, and you have to fly halfway through, huh? I don’t think I’m going to let you clear that!”

That said, the so-called “absolutely impossible placement” must have been based on Nanaya, the goddess, or the so-called “impossible” Dungeon, where you had to fly or breathe for an hour to clear.

That’s where hunters use the cheat known as divine protection to conquer the traditional dungeon balance.

“…Quiet talk.” Piltory drew a line on the Dungeon Map and found the shortest route.

It hadn’t even taken five minutes to get there. The guards hadn’t shown any signs of finding us yet, probably because of the “Anti-Search” stab.

“Okay, looks like it won’t take long! …Or so I thought, but I guess the boss room is inevitable.”

The pilgrim looked at the map and sighed.

The boss room was one of the facilities that could be set up in a dungeon, and it was set up so that you couldn’t pass through without defeating monsters. It was a time attack-crying facility.

Since they had to fight fairly and squarely, it was inconvenient for the four noncombatants participating in the operation this time.

“It’d be nice if Hazel-nee were here.”

The pilgrim murmured the name of his sister, who held the strongest force in such a head-on battle, but the fact that she was the strongest force meant she had to leave the defense of the wight to him.

That was the common understanding among Nanaya’s shrine maidens.

(If the real Hazel-nee was as strong as I was, would I have been able to stay with Papa forever as his bodyguard… withering away?)

Despite such bold thoughts, the pilgrim again steeled her resolve, realizing they would have to break through this place alone if they wanted Yuuto to be happy.

And then, she smiled with a perfect score. For her, having fun was the very thing that made her ready for battle.

“Well then, shall we go? Ready!”

With that, the pilgrim dived into the seawater.

Even though we were in the middle of enemy territory, the first thing she thought about was pretty cold and comfortable. It was an extremely cheerful impression like she wanted to dive in with Yuuto and everyone else.

However, enemy territory is enemy territory. When the pill part dives, the seawater filling the hole turns bright red. Upon closer inspection, it’s the light of a light embedded in the wall.

And then there’s Be! Bee!

“Whoa! Shut up!”

The pilgrim immediately covered his ears.

The next moment, a loud beep rang out.

“If we go into the Dungeon in the first place, the Master will find out… so I guess it’s like I’m letting the ‘something’ inside the Dungeon know?”

A shrill alarm sounded at the bottom of the bottomless sea. Any normal intruder would have panicked at this point.

Meanwhile, the pilgrim calmly considered the intent of the mechanism inside the Dungeon.

However, there was no point in thinking about it, and a few seconds later, the pill part would learn the true purpose of this beeping sound.

-If she hadn’t borrowed Saryu’s race skill, “Five Senses Enhancement,” it would have been a little too late to supplement the one lurking in the darkness.

With a rumbling sound, something rose from below, and it was a super-giant la bu ca.

From the depths of the unlit ocean floor, the thing, just as thick as the undersea cave leading from the lake’s surface to a pillar, was coming up with a big mouth open.

It had the same mass as the building that stood in the heart of the city, and by making its entire body sway like smoke, it created speed as it closed in ferociously.

Its silvery glow made it look as if an undersea volcano had erupted, its ashes soaring into the air.

However, when he saw its enormous, inorganic eyes and pointed teeth, he would immediately realize that volcanic ash was better. That was how terrifying the deep-sea shark’s face was.

…However, the sheer size of it was nothing more than a source of excitement for the pilgrim who pursued romance.

“Whoa, it’s huge! Amazing!”

Her eyes sparkle, and despite being underwater, she doesn’t even try to hold back her voice. A large amount of bubbles pour out of her mouth.

“Ahaha. You’re D-Rank like Rosina-chan and Egrentine-chan, but you don’t have a big body.”

And then, in the next instant, she was preparing for battle…and starting to activate her Skill.

She felt romantic about the giant monster, but she felt more idealistic about the sight of a hero defeating a giant monster.

“I didn’t think I’d ever get to use something like this myself! It’s a huge invention that benefits from doing it after all!”

The pilgrim spread its arms wide, and a black hole appeared behind it.

That was the alternate dimension created by Saryu’s race skill Item Box

“Item Box.” Combined with the name’s stupidity, the fiendishness of that skill wasn’t well known in human settlements

Originally, this skill was rarely given to beings with advanced intelligence like humans since it was allowed only to monsters with low intelligence.

It was a skill with many bindings because it was powerful, but when a being with enough intelligence to scratch through it used that skill, it had an effect like high-ranking divine protection.

A wooden structure appeared from the darkness behind the Pilgrim’s back. Upon closer inspection, it wasn’t a building but an extremely large ballista that could be mistaken for a building.

Made of black wood, it was reinforced with iron plates, showing off to those around it that its body wasn’t visible. Normally, it would have sunk into the water without a trajectory, but now it glared directly at the giant lovely as if it had found the enemy army’s general.

And that weapon, just as large as that deep-sea shark, didn’t originally sound like a ballista’s mechanism meshing—it sounded like a drum being pounded with all its might.

That was because when too fast an arrow was fired, it created a large wave and struck the entire surface of the cave wall with a high-speed wave.

Just as his voice echoed in the cave, the ballista had made an explosion loud enough to echo through the water-filled space.

“Okay, boom.”

And then, the arrow shot from top to bottom, hitting Rabka in the brow far faster than a natural fall.

Burying the entire passageway means, on the other hand, that even if you shoot randomly, you can hit it.

That arrow had pushed back several dozen tons of stupid giant life forms with pure force alone.

The pilgrim nodded in satisfaction at its power and formed a smile.

…Just as Margarita is a negotiator and Biondetta is an intelligence operative, the position of Pilgrim is an inventor.

That said, the wight didn’t know how to make heavy weapons. No matter how hard he tried to draw up the blueprints, the crossbow was the only weapon he could make.

It had already been used in human countries, and it couldn’t be called over technology or knowledge cheating.

…But even with something like that, Pillippert believed in the wight and spent two years creating it. Because of that, her inventions as an inventor were limited to ten at most.

But such a reinvention was by no means meaningless.

The ballistic made by Pillippers were not widespread among humans but were the right size and thickness for monsters to use, and their power was incomparable to what humans used.

She had made several such monster-standard weapons herself, and even this ridiculously large ballista couldn’t possibly exist in human society…or in Etina, of course.

Those arrows are so powerful that they betray all intelligence’s expectations.

The power of that arrow, which could only be fired once, was tremendous, and even a hand alone was thick enough to bind a hundred humans together.

…But either because she didn’t even have the intelligence to flinch from the pain or because of the skill’s effect, even though she was bleeding violently, Loveka continued to rise.

But the pilgrim grinned and said, “That’s exactly why.”

“Very well. Then let us meet them!”

When she spread her arms wide again, many crossbows lined the underwater passage.

“I’ll have you accept my collaborative technique right away. It’s a combination technique of my Remote Control and Saryu-chan’s Item Box. Gate of Babi… is no good, so maybe I should name it Meteor Rain Turner’s Rain.”

The pilgrim took the shape of a pistol and pretended to fire with a “pant.” Even though she was underwater, her scarf was flapping because she had cast a simple wind spell to show off

At the same time as she pretended to pull the trigger, many arrows shot out with a crunching sound… In reality, she was only using two skills simultaneously, so it wasn’t a technique or anything, but her firepower was worthy of being called a secret technique.

The rain of arrows pierces Labka’s skin, unconcerned with the dampening of its power underwater.

Just before it reached the pilgrim, Loveka was riddled with holes at a point about twenty-five meters long, sinking to the bottom of her breath.

“Wow. There’s so much blood. I don’t want to swim here anymore! Ahhh, I should’ve used poison instead of trying to act cool.”

…The pilgrim grumbled while looking at the bottom of the hole that had become a sea of blood.

But the next moment, she said, “Oh, that was fun! I wonder what kind of enemy she’ll have next,” and smiled as she dived into the deep red sea.

As a member of the Machine Tribe, Pillippert had little emotion when he was born.

Because of that, her personality had mostly been cultivated during her time with Yuuto, and the only reason her brain was a field of flowers was because Yuuto’s teachings were a field of flowers.

However, that was why every time she felt joy, she felt that her existence was all thanks to Yuuto, and she didn’t have time to remember the sadness and hatred she hadn’t been taught that much.

“Eeheehee. I’ll show Papa that photo of that loveka. I’ll have to take it before the repo!”

And since she couldn’t stop dreaming, her heart skipped a beat at her chat with Yuuto as she took selfies with the corpses on the battlefield.
