The Immortal World had truly become silent.
Due to the battle between Wei Cheng and the Wood Spirit Supreme Sovereign, an unknown number of low and mid-level forbidden lives perished on a grand scale, and the Sky Demon Tribe, at one point, was decimated to the point where only a few Alien Immortals were left trembling.
As five hundred thousand years passed, the Sky Demon Tribe's numbers hadn't restored to even one millionth of their former count.
The Human race had also quieted down under the influence of the Era Curse, as a great number of Immortals saw their lifespans rapidly decrease, constantly falling.
In just a short span of five hundred thousand years, the number of Immortals of the Human race had dwindled to less than one-tenth of what it once was.
Many of the Immortals didn't even have time to prepare before they passed away suddenly, leaving only their natal Cultivation worlds lonely embedded within the Forbidden Pit.
