Comments of chapter undefined of Magical Journey (HPxMCU)

I dont understand why he need a book or library when he first used his system on getting the knowledge of the mind in the past 100 years and Occlumency he didn't have any books to scan so can't he do that to all the magical subjects and if anything he should even be able to specify so it becomes quicker like the knowledge of all rituals that give positive effects in the last however many years

thanks for the chapter (power stones inbound)

great keep up
