The Innate Dao Sovereign could reverse cause and effect, possessing the ability to manipulate time and space.
However, due to Pangu Great God's presence at the source of the River of Time and Space, which made the past constant, this ability was almost unusable, but it definitely existed.
The ability to manipulate time and space was not only expressed in reversing cause and effect, but it also allowed the Dao Sovereign to traverse the River of Time and Space.
Since one could navigate the River of Time and Space, everything in the past could naturally be scrutinized. In theory, the Dao Sovereign could know everything that had happened.
But theory is, after all, just theory, and different from reality. In the Prehistoric World, there weren't only Innate Dao Sovereigns, but also beings stronger than them, such as Quasi-Saints, Great Divine Transcendents, and Saints.
