I raised my sword, and the presence reached me in an instant. I couldn’t see what it was, but I knew it was there. Not even my detection skill was helping much in this situation.

Even though I could sense the monster’s presence, it was extremely faint. I couldn’t tell what kind of attack it would make or even its form. Fortunately for me, I had the "Black Dragon" sword with me.

[Front! A frontal attack!]

Hearing that, I jumped back and grabbed Mikoto at the same time, pulling her away.

"Luan!? What is that?!"

The ground where I had been standing shattered into pieces. It had taken heavy damage. This monster’s strength couldn’t be underestimated—just like the Black Dragon said, it was strong.

"I don’t know what it is either, but it’s strong."

The monster was invisible. I didn’t even know something like that could exist inside the dungeon. Actually, it didn’t—this monster was new and shouldn’t be here.

Is it because of me?

[It’s coming again! Frontal attack! Dodge now!]

With Mikoto in my arms, I leaped away again.

"I’m going to teleport back to the mansion and leave you there. This could be dangerous."

[Don’t get distracted, it’s coming again! Attack from the right!]

I dodged once more. The wall was struck and shattered into pieces.

"Dragon, can you tell what kind of monster it is?"

[It’s a lizard.]

"A lizard? But it was flying earlier."

[It resembles a dragon. It has wings.]

You can even tell that much? Then tell me its weaknesses and what I should do.

[Its invisibility is likely an ability. If you hit it even once, the invisibility will probably be disabled.]

Got it. I’ll do that.

"Luan?"

"It’s fine. I’ll deal with this quickly."

[Attack from the left!]

After the dragon warned me, I teleported together with Mikoto.

[Good! It’s right behind you and hasn’t detected you yet.]

I turned around and swung my hand, using the abilities "Hellfire" and "Rot."

A black flame shot from my hand toward the monster. Instantly, its invisibility vanished. The fire began to slowly consume its body, and it screamed in pain.

While part of its body burned, the other part began to rot due to the "Rot" ability.

"What is that thing? I’ve never seen a monster like that before!" Mikoto was terrified.

It was a lizard over four meters tall. Its skin was brown, and it had wings. Its appearance was very similar to a dragon.

The flames continued to consume its body.

Even its bones began turning into ash.

’Is this ability really only level one?’

[The skill "Hellfire" has leveled up!]

Oh—it just reached level two.

After some time, the lizard finally stopped struggling and died. But its body didn’t disappear like other dungeon monsters. It remained there, being consumed by the black flames.

It eventually turned completely into ashes.

I took a deep breath and said, "That was easier than I expected."

"What kind of monster was that?"

"I don’t know, but it definitely shouldn’t exist."

"Shouldn’t we report this to the guild?"

Hearing Mikoto’s words, I smiled. "I’ll do that later."

After that monster died, we continued walking through the 40th floor in search of more monsters and the path to the 41st floor. However, we didn’t find any.

’That’s strange.’

I thought there would be more monsters on this floor, but that wasn’t the case.

’Will more monsters that don’t exist in the original story start appearing?’

"What are you thinking about? You look nervous."

"I’m worried. There are no monsters here—it’s strange."

"You’re right. How long have we been walking? An hour?"

"I think more than an hour. Finding the path to the 41st floor is also proving difficult."

After that brief exchange, we fell silent and kept walking.

After another half hour, we finally found something.

A path—finally.

"Is that the passage to the 41st floor?" I didn’t really have information about this. Even in the original story, I don’t remember detailed explanations about every floor and passage—especially deep ones like this.

We moved forward, and as we approached, the Black Dragon spoke.

[There’s a strong monster inside.]

"So it’s not the path to the 41st floor."

"Huh? How do you know?"

"The dragon told me. He said there’s a monster in there. It’s probably a room or something."

"That’s..." Mikoto was visibly nervous.

’Yeah... if this is a room where a monster is hiding, it’s probably a very strong one. Like a boss room?’

"Boss room?"

"Yeah. Rooms where strong monsters hide—stronger than the rest."

"I see."

"This is probably the strongest monster on this floor. Black Dragon, how strong is it?"

[Stronger than the previous lizard. But don’t worry—you can handle it with that fire ability you used earlier.]

"I see."

"Do you want me to stay outside? It could be dangerous," Mikoto asked.

"Come with me. I’ll make you stronger." I smiled and held her hand.

Even though she was clearly nervous, she followed me, and we entered the room.

Inside, we found a monster sleeping.

’Another lizard—but much bigger than the previous one. And its skin is red, like fire.’

Mikoto held her breath.

"Don’t worry, this will be over faster than you think." I let go of her hand and walked toward the lizard.

Then its eye opened.

Its yellow pupils locked onto me as it stood up instantly.

"Six or seven meters tall? You’re pretty big."

But unlike the previous one, it couldn’t turn invisible.

This will be easy.
