The First Elder of Dark Clouds Bird Shrine paused momentarily before he said, "However, the Muscle Hyperthymesia Grass' fragrance is also extremely poisonous and can seriously damage the muscles in a body. Dark Clouds Bird Shrine uses it with extreme care. Otherwise, one wrong move and the avian-fey nurtured with it would be poisoned to death."
A troubled look came over the First Elder's face.
He talked about the Muscle Hyperthymesia Grass with slight terror, and it was clear that he hated it as much as he loved it.
"After avian-type feys are born, they are triggered using residues of the Muscle Hyperthymesia Grass' scent to give them the ability to memorize complicated flight routes perfectly. It also enables them to produce specific responses after they hear the name of particular locations. Our Dark Clouds Bird Shrine has learned a lot after the deaths of countless precious avian-type feys."
