I See...
The Fate Star Method was the most shocking of them all. It was using a person's very Fate to refine them into a corpse puppet, allowing one to commandeer the luck of their corpse puppet, incorporate it into themselves, and distribute it as you pleased.
Ryu only described these methods at a surface level, but each one was truly shocking.
Ryu had to create the [One Above All] Dao Method before he could use his Dao Heart the way described in this refinement method. And the fact he wasn't struck down choosing such a name went to show just how powerful his self-created method was, and yet here was a refinement method that used the same concept.
The Bloodline Method seemed to be the most lackluster of them all… until one realized that the bare minimum requirement for its use was a Lord Grade Bloodline; otherwise, it would lead to a worthless refinement.
