Many pieces of knowledge in necromancy are passed down in the same mentor-disciple form as Malcolm's.
Primarily because necromancy spells are highly dangerous, and the wizard organizations in the wizard plane do not wish for such knowledge to be widely spread, as it could easily lead to uncontrollable events.
The Boundary Land, in this aspect, is much more lenient, treating necromancy knowledge no differently than any other.
However, there are restrictions and requirements for studying and experimenting with necromancy, such as the fundamental rule of not harming others.
In fact, not many people in the Boundary Land are willing to voluntarily study necromancy, as it involves constant dealings with corpses, the undead, and skeletons.
After Herag finished learning these basic concepts, he took out a piece of parchment and made a book list for himself.
The list was very long, containing seven to eight hundred books.
