"Kijin-san, hey."
『What is it?』
"See anything? Like, the presence controlling this ruin or something?"
If there's no such presence... that would mean the ruin itself decided to attack me, which is just absurd, but it's starting to feel like the only explanation.
『Nothing out of the ordinary caught my eye... It really does seem like this ruin itself developed some kind of will and chose to attack you.』
"Alright then, let's just smash the whole thing."
If the ruins are acting like a monster, then there's no reason not to destroy it. And even if the attack was actually caused by some hidden enemy using the ruins, the dungeon's structure usually regenerates. As long as it's part of the dungeon, it'll probably rebuild itself... probably. No need to worry too much.
: Aren't these ruins super valuable or something?
: Can't prioritize treasure over staying alive, dude.
