Ghost Immortals, although ranking penultimate among the five realms of heaven, earth, mortals, spirits, and gods, surpassing only the divine immortals who depend on the titling by the Heavenly Court, are still undoubtedly part of the Immortal Realm. Once one steps into this realm, one has found the grand path to eternal life.
While Bull Head has a foundation comparable to that of a Heavenly Immortal, his actual cultivation realm is still within that of the Ghost Immortals due to the limitations imposed by the world itself, and even with all his methods, he could not possibly kill a Ghost Immortal with a single strike.
A sneak attack by Bull Head, using his own strength, could at most inflict severe injuries on the Nine Yin Ghost Immortal but would unlikely affect the overall situation.
Thus, after finalizing the strategy, Shen Yuan personally bestowed the "Extinguish" Imperial Edict, employing the Unimpeded Netherworld and Gods Purging divine powers, and sealed it inside a dagger.
