If it were placed too conspicuously, it would have aroused the Fierce Destructor Roc's suspicion.
One or two minutes later, unable to resist the fragrance any longer, the Fierce Destructor Roc almost fully entered the cave, when suddenly, there was a loud noise that was come from outside.
The loud noise startled the Fierce Destructor Rocs, causing it to retracted back half of it's body after halfway into the cave.
Amalia and her companions initially thought someone was causing trouble and they are already expecting the Fierce Destructor Roc to flee.
However, they noticed it still remained at the mouth of the cave and emitting an angry cry.
Responding to the Fierce Destructor Roc angry cry was another cry of the same species but with a different meaning, and Amalia and the others instantly understood.
This was a stroke of luck.
