The Exiled Royal Architect Develops An Island With Magic Construction Equipment And Fluffy Animals

”Having the strength to even corrode mythril, the King of Decay is the worst king. As one of the beings in existence called the Demon King, if he ever resurrects, we’re finished.” (Jay)

Jay explained about the King of Decay. But why was such an atrocious being sealed away on this island.

”First time I’ve heard of him. But who in the world made such a seal?” (Wirk)

”An ancient magician, apparently. It was my father who found the seal, but there was an ancient document left behind near the seal. It also mentioned the magic black stone.” (Jay)

I see. And Jay’s father was the previous generation’s king of the dwarves.

”The only thing that the King of Decay cannot corrode is the magic black stone, which was produced from magma. That’s why the magician back then used it to complete the seal.” (Jay)

I see. Certainly, the magic black stone is resistant to corrosion.

”However, the ancient document stated that the seal wouldn’t last forever, but would weaken over many months and years and eventually be broken. My father thought that, as it was, the seal would come undone in the near future, and so he devoted himself to the metallurgy of the magic black stone. But in the very end, he passed away and the mission was passed on to me.” (Jay)

”I see. But how did that lead to blacksmithing with magma?” (Wirk)

I thought of something that made me think “there’s no way”, but I asked just to make sure.

”The magic black stone seems to have been completed after the ancient magician continuously used magic while making use of the magma for three days and three nights.” (Jay)

Eh? Three days and three nights for only that much?

[TL: Congrats to our MC, because you have just earned [Achievement: Start a Harem]! Yes, I know, I could have seen this coming, but nothing happened that could properly justify it until now. Anyways, I’ve adjusted the tags and such to include Harem, both on this site and on NU. Raise your hand if you’re tired of harem stories…]
