As far as Cyril knows, this potion can even help them just by spraying it on their bodies... This is why he knows that he wouldn't disappoint them at all.
The two centaurides didn't immediately decline or accept the offer as they spoke with each other silently. The reason they are taking the Iron-back Apes' bodies was that their meat was very nutritious.
They were also difficult to find around this forest since they would always hide upon seeing the centaurs or whenever they smelled their scent.
They were supposed to give them to the injured centaurs at the nearest settlement… However, if Cyril is telling the truth, then she wouldn't mind giving all their shiny beads at all!
"Are you telling me that a single flask can help many of us?" Cilleina asked. She looked deeply into Cyril's eyes as if she's capable of telling the truth and lies from his words.
