"I am Esil, the first-born daughter of House Radiru. And my clan is..."
"No, not that."
Jin-Woo cut Esil off.
He didn't really care about the finer details of a monster family's history. What he wanted to know was the reason why monsters and instant dungeons existed.
How should he go about asking this question, so he'd get himself a satisfying enough answer?
No, he would still be okay if there was no concrete answer. He'd be happy enough to get a single clue, a lead of some kind.
He tried asking the same thing to monsters in the regular dungeons, but the only thing he got to learn was that they could only hear the order of 'Kill the humans' inside their heads.
'In that case, do these guys receive the exact same order, too?'
In order to help him compare the current situation with the monsters of the regular dungeons, he simplified the question a bit.
"Hey, do you also hear a voice telling you to kill humans?"
"Pardon me?"
Esil looked at him with a pair of confused eyes.
(TL: Yes, the raw said 'darkness', not shadow. I'm guessing the author wanted to be a bit more 'literary' there if you will, so I let it be.)
