The Sword Sheath of Subdue Evil, as a part of it yet also considered an external object, was the first to separate and endured the most erosion from the Heavenly Demon, eventually transforming into a world.
Meanwhile, the Sword Ornament of Subdue Evil, or the sword's pommel, was similar. This purest treasure bead also evolved into a world.
These two worlds, An Jing has yet to explore, are evidently the most distant worlds requiring him to become stronger to sense them.
Yet, afterward, the Sword Blade of Subdue Evil, representing edge and fury, is evidently absorbed by the Great Wilderness Realm. Honestly, as described by Master Mingguang Dust, this realm indeed feels quite violent and sharp. It's hard to say if this world is inherently compatible with the traits of the Subdue Evil Sword Blade, hence accepting it, or if it was altered by its attributes.
