Over two hundred years had passed since the last time he acquired more than four thousand top cultivators.
For immortals, this span of time was just a flick of the finger, far too short.
However, for mortals, it was enough for a dynasty to rise and fall, hence far too long.
Only to cultivators, it was just right.
Based on the ninety-nine-tiered ladder structure of cultivation,
a qualified cultivator, from cultivating their Primordial Spirit to stepping onto the ninety-nine-tiered ladder, only needs one thousand years.
This is a watershed.
Exceeding it meant one was unqualified and should arrange their affairs earlier, for their lifespan would be insufficient.
If it's done in less than a thousand years, that's a genius.
And such geniuses, within Wei Cheng's lifebound cultivation world, now number at least a billion!
They will enter a mass era of ascension in the next thousand years.
