A Brief Explanation of This Book's Ability System

Generally speaking, the power system in this book is based on the premise that it "does not deviate much from the settings of One Piece".

As Sig's cheat ability, the Paths of the Divine can only manifest abilities that can be explained using the native powers of the One Piece world.

In other words, overly powerful abilities can be weakened (which can be understood as being out of step with the rules of the world), while some seemingly insignificant abilities may actually be crucial.

For example, "the ability of Telepathist to read emotions becomes a special Observation Haki," "the Distortion knowledge heard by listeners becomes the ability to absorb Devil Fruit," and "the People of Fury is similar to Fish-Man"...

Regarding the question of "not wanting to see too many Devil Fruit ability" --

First, the protagonist's acquisition of the Devil Fruit ability in the book is equivalent to the "Listener" gaining secret techniques by listening to Distortion knowledge. This is itself part of the Paths of the Divine's cheat ability, not an ability outside of the cheat ability itself.

Secondly, I can give you a spoiler: the later analysis of the "White Tower Path" and the ability to learn other Pathway will also be reduced to learning Devil Fruit ability, not the normal multiple Devil Fruits. Just like when the Polymath in the White Tower Sequence in Mystery learn other Pathway ability, it will be incomplete and weakened. Later, there will be "multiple half-baked Devil Fruit ability." Readers of another book, <The Great Jianghu: Hotspot Hero>, should be familiar with this pattern.

Regarding the question of whether "High Sequence are too powerful in the One Piece world" --

Indeed, the High Sequence are too powerful. Advancing to Sequence three is the end. Just look at the progress; before the book was released, even Sequence 8 wasn't enough to complete the story. The first six Sequence were sufficient for the entire narrative. There's no possibility of the story collapsing after the High Sequence, because it's already finished...

The above settings will not be significantly changed.
