Michael quickly realized that the books stored in the Library of Laxartia were extremely valuable to him, his subjects, and his territory.
They were not just ordinary novels of ancient times but had detailed information about the Origin Expanse, guides related to raiding ruins, manuals on how to train Grandmaster Artisans, martial art techniques, training techniques, how to combine different techniques to create a superior technique, and much more.
All in all, Michael was unable to leave behind any of the books. According to him, the extraordinary knowledge stored in the books shouldn't stay in the Lord Rift. It should be taken outside and utilized properly. That was also why Michael never stopped using Extraction to extract the Wisps of Knowledge even after his head began to ache.
