Uninhabited Island Level 9999: Creating the Strongest Island Nation with Uninhabited Island Developm

Chapter 84 – A Modified Dungeon

We entered the cave and went all the way to the back.

I found the “staircase,” which serves as the entrance to that dungeon. Eduardo stared at that place with curiosity. It seems like she’s observing something.

“Why are you tilting your head? This dungeon was created by the great sage Eduardo, right?”

It is said that the great sage has such ‘extraordinary abilities’, as one would say in her case. However, this reaction is subtle.

“That’s correct. This is a ‘random dungeon’ created by me. However, it seems that the specifications have changed a bit.”

“I see. What feels off about it?”

“A while ago, the Knuckle Kobolds appeared on the surface. Could it be that it happened before?”

That’s right, it applies to Grimbrusti, Gruen Goblins, and Executioners. They emerged from the cave and attacked us. But I thought it was natural, but it seems to be a bit different. I told Eduardo about those past events.

“――And I also fought against slimes.”

“I see, it seems that the monsters that escaped from this dungeon have settled on the island. And, on rare occasions, monsters seem to have washed up on other continents as well.”

“Is that so?”

“There are many monsters that can swim, and if it’s a flying type, it’s no problem.”

They’re probably birds or dragon-type. I haven’t encountered any yet, but there must be many of them inside the dungeon. And such monsters are rampant in the world…

“So, does that mean that the Sage is responsible for the damage caused by monsters all over the world?”

When I asked, Eduardo shook her head and denied it. Apparently, it’s different.

“That’s the source of the unease. Normally, dungeons created by great sages are impossible for monsters to enter or exit. So they should be blocked by a special barrier and unable to get out into the outside world…”

“But they’re coming out.”

“Perhaps someone has ‘modified’ it. As evidence, the mark of ‘Einherjar’, the symbol of immortality, is engraved on it.”

Einherjar… I remember, that’s what Havamar told me about. It was the cause of the Holy Demon War in the legend. The reason why she was made into a demon king.

Upon closer inspection, there was a mark of [Ψ] engraved in front of the staircase. What’s this… a trident?

“This is…”

“That is indeed the symbol of Einherjar. I have the same one on my lower abdomen.”

“On your… lower abdomen?”

I unintentionally stared at Eduardo’s navel area, and… wait, there!? Could it be… I’ve heard of it before, but it’s the so called “Ero Mark” or something like that. It’s knowledge from erotic books! I’m a healthy guy, so I’ve read about those things. But I never thought such useless trivia knowledge would come in handy in a situation like this.

No, but still, Eduardo does have the ‘Einherjar.’ And it’s on her lower abdomen… This might be the real deal, an item of immortality.

But I have my doubts.

I remember Havamar said that Einherjar is an item. So, what about this mark?

“Tell me, Eduardo. What is this symbol in front of the staircase? And why do you have the same mark engraved on your lower abdomen?”

I desperately wanted to know, so I questioned Eduardo. But I asked her politely so as not to scare her. Then, Eduardo started taking off her clothes――Wait, what!?
