And the reason they descended upon this world was that the true Immortals of their Immortal Sect had divined that the True Spirits of this world had already been completely obliterated and the celestial secrets were thrown into chaos, and the Heavenly Dao no longer clear.
Even though real Immortals still could not set foot in this realm, as their cultivation would suffer otherwise.
But through special means, they could send members of their Immortal Sect down through certain fissures, either seizing new bodies or reincarnating.
Turning them into people of this world.
Afterward, they would seek to capture the true essence of this world and ultimately refine it into a World Lord.
Within the Immortal World, World Lords are a very special group of existences because as long as they don't provoke those Great Powers at the pinnacle of the Immortal Realm, basically, no one can threaten the safety of a World Lord.
