The floating book suddenly started turning the pages on its own and stopped at a certain page. On that page, there was a picture of a large boulder and that same boulder suddenly appeared before the book and fell toward Tomoe's team. But that was just a simple boulder, so before it could reach then, Kaya cut it in many pieces with her sword.
Grace then informed everyone about this peculiar book. It was a rare and quite well known magic item called Dreamer's book. Only a high level Alchemist was able to make this item, so the presence of this book here was the proof that there was a high possibility that this workshop really belonged to a high level ancient Alchemist.
