"The Ancient Catastrophe severely damaged our world; the Heavenly Dao itself was impaired, compelling a Daluo Realm Elder to reluctantly relinquish his own existence to merge with the Dao. Only then was he able to seal the world, blocking the incessant invasion of armies from other worlds. Later, he actively coordinated with various factions to wage wars for thousands of years, barely managing to quell the conflict."
Ning Wuxu said, "Due to the severe depletion of our foundation, since that catastrophe, our world hasn't seen the birth of any powerful being above the level of a Golden Immortal for a very long time.
Even after tens of thousands of years of recuperation and reproduction, only the lower and middle tiers of cultivators have largely recovered. There are now more True Immortals, Heavenly Immortals, and Profound Immortals, but very few have ascended to become Golden Immortals, let alone reached the Eternal or Daluo Realms.
