Back then, after the Heavenly Dao shattered, the Heavenly Realm split apart.
The boundless starry sky was the Immortal Realm of old, the residence of immortals and gods.
The Moon Palace was on the moon, and the Demon Court's imperial palace was on the sun. It had simply been too long; all the good things had long since vanished.
Besides maintaining the Heavenly Realm and the Immortal Realm, the Heavenly Dao also had the ability to guard against chaos.
Without the Heavenly Dao's defenses, chaos would continuously erode the starry sky, assimilating it into chaos.
If the Heavenly Dao never revived and no saint was born, the Immortal Realm would sooner or later return to chaos.
Of course, that would take a very long time. Most immortals and gods would never live to see it.
Because they would likely be killed by someone else long before then.
From ancient times until now, roughly one-tenth of the starry sky had been eroded.
That was the Demon Court's data. Whether it truly was one-tenth, no one knew.
The ancient immortals and gods had entered chaos from the Heavenly Realm—the present-day starry sky—and ultimately vanished without a trace.
Due to chaos's erosion and assimilation, finding the path those ancient immortals and gods had taken was almost impossible.
Unless one became a Primordial Saint.
Even a Heavenly Dao Saint could not remain in chaos for long. They could only rely on the Heavenly Dao's blessings to establish a Dao field or a small world and resist chaos's assimilation.
Powerhouses such as Immortal Emperors and Divine Emperors could survive in chaos for a while. A few hundred years would not be a problem.
But without replenishment, if they expended their power, they would struggle to last even a few years.
Immortal Venerable powerhouses could survive
