The Ancestor of Runes briefly explained the origin of the curse arts.
"The curse arts encompass everything. Once you cultivate them, you can wield a unique cursed power. Furthermore, the curse inscriptions contain countless ultimate mystical abilities. However, to master these supreme techniques, you need a profound understanding of the curse inscriptions."
"What you must do now is not to comprehend these ultimate techniques, but rather to grasp the core of the curse, understand the Dao of the curse, and enhance the power of your cursed Dao seal in the shortest possible time."
