After receiving their own workshop inside the Invention's Convention, both Kraftvoll and Belle unanimously decided to the library again after Faction Leader Molly let them on their own accords. They started reading a book entitled 'The Introduction To Inventing by Darius von Stolz' following the suggestion of the faction leader of the convention.
After reading the start of the history of art, the two started to read the basics written inside the book.
Previously, Belle already managed to read the first part so she decided to move on to the next one. She read, "The second part of the seishin device is its materials. It may be a part of a carcass of a certain seishin beast. It may be a refined ore created by the blacksmiths of the seishin cultivation world."
