Alchemist O'Hara: Insects here were harmless until a week ago. All of a Alchemist O'Hara: sudden, they turned violent and became hideous Alchemist O'Hara: monsters blocking the road. NakanoAzusa: Did you find anything odd about them? Alchemist O'Hara: I see a lot of wagons with La Cidro's symbol pass this Alchemist O'Hara: road towards Algon. NakanoAzusa: La Cidro's wagon? HiiragiKagami: Could it be the Illusion Stone again? Monsters who HiiragiKagami: were influenced by the spirit control machine in HiiragiKagami: Amarkand suddenly turned violent, too. NakanoAzusa: That may be. But La Cidro already completed their NakanoAzusa: experiment with the Illusion Stone. Why would they NakanoAzusa: install spirit control machines again in this area? HiiragiKagami: Or the dark energy of Zereca could have drastically HiiragiKagami: increased! Alchemist O'Hara: If there's no concrete answer, we would have to do Alchemist O'Hara: some research. I've been studying insects here since Alchemist O'Hara: a long time ago and have samples of them before Alchemist O'Hara: they changed. I may discover the cause if I compare Alchemist O'Hara: the samples. For that, I would need their skin. NakanoAzusa: Their skin? Alchemist O'Hara: Yes, I can use their skin cell to compare the tissues.
