After getting close to that place Livia and her teammates are finally able to notice those Monsters using their spiritual fission and they become happy as they could show those Golden eyes cats in front of them. It looks like Livia's strategy was right. Because even though those Monsters notice The Spiritual fluctuation, they did not think it would be closed to them as they could feel the spiritual fluctuation very light and most likely the source of The Spiritual fluctuation very far away from them.
One thing you should know about those Monsters is that they did not pick up fights with any other Monsters or any Warrior on their own. Those Monsters would only try to attack any Warriors if a Warrior or that group of Warriors try to attack them first.
