However, before this, they would absorb the massive energies released during the world's destruction and rebirth as they grew.
It was because of this that they grew increasingly powerful.
With their newfound power, they might assume the responsibility of saving the world because they thought themselves natives and become saviors, but it was also possible that they turn into demon lords due to the despair conveyed by a world on the brink of collapse.
This all remained uncertain, but one thing was constant:
Whether they became saviors or demon lords, they ultimately would destroy the world they were in themselves, then ascend back to "home" as Ascenders, becoming the mainstay who could serve "home", and in cases where the destroyed world was vast, they directly acquired the power to become higher beings.
As for the destroyed world, it would change and evolve over a long span of years, eventually forming a new civilization.
