Reincarnated into a World Filled with Dungeons, But My Blessing Turned Out to Be the Most Challenging Dungeon

“This is getting a little ridiculous…”

Looking down from where I stood, I saw a vast chamber about five meters below.

At the center of the room, embedded in a pedestal, was a stone that appeared to be the dungeon core…

『Why does that matter? Just swing your log around like usual and wipe them all out.』

Eve casually suggested something absurd, as if it were the most natural thing in the world.

“No, look—there’s a Direwolf, a Troll, and even a Salamander. Taking on a mix of B-rank monsters all at once is pushing it.”

The chamber was packed with monsters, all stationed as if they were guarding the dungeon core under strict command.

『Is that so? If you combine magic with your attacks, I feel like you could handle it.』

I turned to Eve and told her one important thing.

“Yeah, about that… I’m more exhausted from using 【Repair】 yesterday than I expected.”

I had never really felt fatigue from expending mana before, but this time, my whole body felt sluggish.

Judging by my condition, I’d be lucky to cast two attribute spells before I hit my limit.

Would a single night of rest at an inn not be enough to recover? Or is it just because my mana reserves are that massive?

『We should have prepared more mana potions.』

I had brewed plenty of stamina potions to cure Eclair’s illness, but I had only experimented with making mana potions without stockpiling them.

Until now, I’d never depleted my mana reserves completely, but thanks to 【Amplify】 allowing me to use higher-tier abilities, I should probably start keeping some on hand.

『So, what do we do? Should we return to The World, rest up, and recover before coming back?』

That was one of my biggest advantages.

A normal party would have no choice but to push forward despite their exhaustion, but I could retreat to a safe zone, recover completely, and then return at full strength.

This method was only possible because I had secure food supplies and a guaranteed safe area.

“No, I already unlocked the dungeon entrance. If I leave now to rest and someone else clears it while I’m gone, that would be a problem.”

Even if it was a well-hidden dungeon, professional dungeon explorers were not to be underestimated.

『Then what’s the plan?』

Eve asked, and I replied without hesitation.

“How about we try some good old-fashioned party play for a change?”

“Alright, Kaiser! Distract them! Eve, lay down suppressive fire with magic!”

“Kueeeeee!”

『Understood!』

As soon as I dropped into the chamber, the monsters locked onto me all at once.

“Their movements are slow and predictable. This is manageable!”

I slashed at a charging Salamander with my azure short sword.

The severed flesh instantly froze over, and the light in the Salamander’s eyes faded as it collapsed, lifeless.

“Nice! Keep it up, you two!”

If fighting alone was too risky, I just had to increase my numbers.

Since I couldn’t afford to use magic myself, I had Eve handle that part, while Kaiser focused on outmaneuvering the enemy to prevent us from being overwhelmed.

Thanks to them, I had a secure position and only needed to deal with a few enemies at a time, gradually shifting the battle in our favor.

“Alright, now comes the crucial part! Stay sharp!”

At my call, Eve and Kaiser responded in unison—

『Leave it to us!』

“Kukueee!”

Their voices echoed with determination.

『Master, look out!』

“Gyaaahhh!!”

“Kueeeee!!”

“Gurururuaaaaaaa!!”

“Uh… what?”

I stood there, gripping my short sword, completely dumbfounded.

Because as the battle progressed, the monsters stopped coming toward me entirely.

『Master is exhausted. Kaiser, don’t let a single one through.』

“Kuek, kuek, kuek!”

Right before my eyes, the battlefield had turned into a massacre.

Eve’s powerful magic rained down upon the monsters, while Kaiser swiftly cut down any that tried to escape.

And they prioritized eliminating any enemies that approached me, leaving me with no role in the fight at all.

To be honest, with just these two, we probably could have managed from the start.

Eve had been growing stronger in tandem with my own progress, but even Kaiser had significantly improved since we first met.

At this point, could we take on an A-rank monster in a fair fight?

“You know what? I’ll just sit back and watch.”

I had suggested party play, thinking I’d contribute, but it was clear that they were going all out to give me time to rest.

In that case, I should just accept their kindness.

And so, for a while, the chamber was filled with the overwhelming spectacle of sheer destruction.

『Kueee!』

『Master, we’ve wiped them out.』

Kaiser rubbed against me, clearly expecting praise, while Eve spoke with a satisfied tone.

“You two did amazing!”

I praised them while patting Kaiser’s head.

『Still, something feels off about this dungeon.』

“Hmm? What do you mean?”

As I collected the magic cores from the defeated monsters, Eve voiced her suspicions.

『Dungeons are structured to be cleared by explorers. Monsters usually roam in set patterns, and a boss is stationed at the center. But this time, once we dropped down, we couldn’t climb back up without killing all of them. Plus, they had gathered an unusually large force.』

“Now that you mention it…”

It was strange.

Even with ten B-rank monsters mixed in, the sheer number of enemies was overwhelming.

If not for Eve and Kaiser, I wouldn’t have attempted this fight. Even an S-rank explorer party would struggle to clear this.

A large group would lose members to traps along the way, and even if they reached this point, they’d be forced into a desperate fight against overwhelming odds.

And since this was a Rank V dungeon, returning to the surface would take considerable time. Factoring in rations, adventurers would have no choice but to push through.

In other words, this dungeon was far harder than its supposed rank suggested—due to someone’s deliberate interference.

『Still, even after searching, we haven’t found anything. I doubt this setup was just a coincidence.』

Eve furrowed her brow in suspicion.

“Well, whatever. I’m exhausted. Let’s grab the core and head back for now.”

Even if they were just trash mobs, fighting through that many was draining, especially since I wasn’t at full strength.

『Agreed. If there’s nothing else to investigate, let’s go home. I’ll even give you a special service tonight.』

Ignoring Eve’s teasing remark, I reached for the core.

It was a deep red and brown stone, split evenly between the two colors.

“Alright, let’s use the teleporter to head back and—”

『M-Master! Something’s coming!』

At that moment, a magic circle lit up in the center of the chamber—

“””GAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!!”””

A monstrous beast with three heads let out a deafening roar.
