Bringing the dead back to life was not considered unusual in the Primordial World, where immortals and gods held sway.

Of course, for ordinary resurrection, the target's Zhen Ling and soul had to remain.
Even a Remnant Soul would suffice.

But if someone had died so completely that not even a trace of Remnant Soul remained, vanishing entirely from the Primordial Era Universe, then even if a Primordial Chaos Saint acted personally, it would be impossible to conjure that person back from nothing.
A Sage might perhaps use powerful divine abilities to turn the unreal into reality and evolve an identical resurrected person.
But that would only be a living being copied by the Sage.
Even if their personality, memories, physical body, and genes were completely identical, they would still merely be a copy and could not be considered truly resurrected.
As lifeforms evolved by a Sage, their potential would also be locked. They could never break through the restrictions imposed by the Sage.
When immortals and gods fought, those with especially ruthless methods would completely destroy their enemies' Zhen Ling and souls.

Thus, in the cultivation world, those who died in battle usually had very little chance of reincarnation, unless it was a great war like the Investiture of the Gods War, with the Investiture of the Gods as a safeguard.
Otherwise, the number of people who reincarnated would be extremely small, and those who
