As for the current Ancient Cosmos, it was merely an underdeveloped defective product. Not even a complete high-dimensional spacetime existed—only dimensional fragments approaching the high-dimensional level, scattered one after another.
The mortal universe representing the low dimensions was likewise scattered like isolated islands in the sea, far from a whole. Every 1.2 billion years, heaven and earth underwent an epochal cycle.
As for spacetime structures of even lower dimensions, they could not manifest at all.
The Earth Universe, meanwhile, was the center of the mortal universe. As for why, it was simply inevitable. From the moment the Sword Seed chose this universe, it had already been destined.
For if it had been elsewhere, then the place where the Sword Seed emerged would inevitably have been another universe.
And once the transformation was truly complete, perhaps the area of Earth alone would rival that of the entire present-day Ancient Cosmos. As for humanity on Earth, the essence of their lives would naturally rise along with this transformation.
At the same time, the changes in Primordial Spacetime would drive changes across infinitely many parallel spacetimes. By then, who knew whether every parallel spacetime would be warped by Primordial Spacetime? Primordial Spacetime itself was the most dazzling sun among all time and space, its light blazing ten thousand fathoms high.
Furthermore, under those circumstances, every parallel spacetime would only be able to reflect a portion of Primordial Spacetime, never its entirety. This would bring sweeping changes to parallel spacetimes, from the structure of their worlds themselves to the paths and trajectories within them.
But those were matters for the future. If that day truly came, Zhao Cheng had absolute confidence that he could meet every challenge head-on.
For now, after completing a round of observation, Zhao Cheng did not pause in the slightest.
