In the Nine Billion World Layers, worlds were nearly infinite.
Among these worlds, which were vaster than the starry rivers, existed a special kind of unique world.
They were the first worlds to be born, and some of them were even older than the birth of the gods.
These special worlds were naturally formed and not created by deities.
Such worlds were collectively referred to as prehistoric worlds.
The world where Gu Qingshan currently found himself was precisely a prehistoric world.
For countless years, the weathering and trials it had experienced far surpassed those of almost all other worlds.
This was simply because the World Origin it contained possessed a single trait.
--Eternal and indestructible.
All things and living beings created by gods inevitably had a beginning and an end.
However, prehistoric worlds possessed the trait of "eternity".
Even those cataclysms in history that could be called all-destroying only temporarily shattered them.
Just a few short years later, their World Laws fused back together once again.
The prehistoric world was then reborn.
Of course, a prehistoric world that had been restored to existence was inevitably somewhat different from before.
For the beings of the myriad worlds, this "eternity" that transcended the deities became one of the things that interested those powerhouses the most.
Quicksand World had experienced a total of thirty-seven Lords of the World, sixty-one natural destructions, nine myriad-world cataclysms, and seven thousand nine hundred and twenty-five wartime destructions.
The book Gu Qingshan held in his hand was the detailed record of Quicksand World around the time of its fifth destruction.
At that time, an Overlord-level powerhouse with heaven-defying means had defeated the former master of Quicksand World and occupied this world.
The reason he was powerful was because he possessed a special ability.
--Self-replication.
He could completely replicate
