With the looting done, I debate for a moment whether we should even mop the floors up, but decide against it. If someone walks through the boss room and sees a bloody chamber with us desperately trying to scrub the floor clean, we would have to fight them to the death as well. As it is, it's evidence that the count's son was murdered here- at least if they have some blood sample identification method- but beyond that we won't be implicated in the crime.
It's better to just dip. I would love to continue our labyrinth grind, however, not only would I have to rest again to regenerate my mana, but with 'stealing' the twin servants and now this noble's murder, we are probably better off just continuing in a few days' time when the scene cools down. Maybe they even had some artifact watching Luke's life signs, and it alerted them of his demise and exact location as well. Better be safe than sorry.
Yeah, let's just leave and have dinner.
