Nothing but blood stains remained on the nursery where the Ghouls were supposed to be staying...
Demon Prince Lu's expression looks twisted as he stared at this. The sheer anger radiating off of his body was freaking the servant demons out, making them unable to even breathe loudly.
The worst part about this is that Demon Prince Lu had no idea where to begin with his search. He couldn't see any traces of the killer anywhere, not even a strand of hair, footsteps, or remnant aura. There's nothing except blood stains and a few bits of flesh.
Demon Prince Lu felt myriad of emotions but the most prominent of all was, of course, anger.
He couldn't believe this...years, nearly a decade of work, gone just like this. And he couldn't even find out how it happened.
