The establishment of a powerful Divine Dynasty is even more challenging than the establishment of a large immortal sect. Nowadays, none of the Divine Dynasties in this world have ruled without deriving from ancient countries, yet none of the Divine Dynasty Lords cultivate the Emperor's Path.
The reason they do not cultivate the Emperor's Path isn't because they are unaware of its power, but because of its difficulties and the many fears it invokes.
Even if someone establishes a powerful Divine Dynasty and becomes a True Immortal, continuing to advance becomes even harder, as the development of a Divine Dynasty differs from that of a Religious Sect or a Sect, facing joint restrictions from various parties.
And trying to switch paths and join the Heavenly Court is difficult because all the suitable positions are occupied by others.
