Almost most of the Earth Grade and Sky Grade Manuals present in the Grand Sea Continent had been implanted with the author's insights and comprehended laws.
It isn't supposed to be that way since it might hinder a person's future comprehension of laws if they were to train and comprehend the same laws as the author.
There would inevitably differences in their comprehension, leading to more confusion.
