Unexpected Battle

[Day 64]

After spending almost, the entire night with Mady, I stealthily went back to the Aquarian Castle.

On the way to the castle, I had some of my sense skills activated and I felt a strange aura coming from the underground part of the Castle.

However, just as it suddenly appeared, it dissipated.

What was it?

It certainly came from something very strong. Nothing like the people that inhabit this Kingdom. Due to this strange presence, I remained cautious.

I decided to remain awake while I investigated the whole castle with various detection skills alongside my [Mystic Eyes]. Afterward, I created 20 flesh and slime minions of small sizes and made them investigate the whole place.

In less than half an hour, the entire facility was completely investigated and mapped, except from the underground. The door that leads there seems to be heavily sealed with countless spells that I couldn't understand.
