"Book of the Dead"
Based on the knowledge Han Dong had learned from the "Prelude Volume," along with the clues provided by Teacher You, he had basically figured out the "volume system" of this First Grimoire.
It used the bodily structure of the Primeval Human as its foundation, dividing the volumes according to body parts.
Aside from the Prelude Volume,
it was mainly divided into three major volumes: the Head Volume, Body Volume, and Limb Volume.
These three volumes were then further subdivided.
The Head Volume was divided into three sections: the Eyes, Skull Section, and Brain.
The Body Volume was divided into the Torso, Organ Section, and the separately designated Heart, likewise totaling three sections.
The Limb Volume was divided into the Hands, Feet, and Bones, also three sections.
By this count, Han Dong's current progress was 1/9. He still needed to search for and deeply study the remaining pages from eight sections... and their difficulty would certainly be no less than that of the Eyes, considering that Han Dong's eyes had the manuscript as a foundation.
Among them,
the Skull Section, Brain, Organ Section, Heart, and Bones,
these five more "internal" sections were classified as dangerous. After deliberation among the Old Kings, rather than being suppressed or sealed, they were directly dismantled and cast into the Shattered Dimension.
The Eyes, Torso, Hands, and Legs,
these four more "external" sections were assessed as relatively less dangerous.
Considering the immense value of the Book of the Dead itself, the higher beings sealed them within various kingdoms and suppressed them with land deeds.
Among them, the Eyes that Han Dong had acquired were suppressed within the Gray Kingdom—Sharnoth.
As for the Torso, according to clues provided by the void,
the body was located in the Deep Sea.
