There were still a few more books left after Mira finished going through the [Mortal Cultivation Realms] and [Dao for Dummies] books. She still had books on Weapon, Body, and Soul Cultivation, along with books regarding the grading system for items and how to make techniques or abilities.
Although Mira was excited to learn more about body cultivation, she had a feeling that the information in the book wouldn't be of much use to her. The same goes for Soul Cultivation. Now that she's the inheritor of the F.LD.I.L, she felt like her path would be slightly different compared to what's known by most people.
Still, these were all things she needed to know in case she ends up facing a body or a soul cultivator in the future.
So, the next book Mira read was the book on Weapon Cultivation, though calling it a book is a bit of a stretch. There are only a few pieces of paper on what Weapon Cultivation is.
