The Immortal-Suppressing Edict

Pangu split heaven and earth, and the Three Realms were divided into nine tiers: three earthly, three heavenly, and three immortal.

Above the ninth tier, only those who hold the Immortal-Subduing Edict can make kings submit and all beasts bow their heads, reigning supreme across the land.

Anyone who defies the edict shall be put to death without exception.
