Only from the werewolves' perspective could one truly appreciate the shock they felt seeing the magical beast chickens easily devour Poison Flies.
That's why so many Werewolf Clan Leaders wanted to buy magical beast chickens from Eternal Domain. Even Long Legs of the Swamp Tribe was willing to exchange the lives of his five Poison Flies for a single magical beast chicken.
If you could raise one in your own territory, the Werewolf Tribes that breed Poison Flies would be shaking in their boots every day, fearing their Poison Flies might one day be pecked to death and eaten by it.
Moreover, possessing a magical beast chicken wasn't just for deterring other Werewolf Tribes; it could also be used to expand the range of one's own tribe's territory.
