"This world, in fact, does not need the intervention of external objects to keep generating life..."
In Lu Ping'an's eyes, whether it's the high-level Elemental Lords of this stratum or the lower-level Lower Puppets, there essentially is no fundamental difference.
Both are native elemental aggregates, both are higher-level aggregated life forms.
They are relatively crude, but their structure is complete, even having a whole set of evolutionary methods tested by time.
Only the outsiders are dissatisfied with them, mainly because the current situation "does not meet their" expectations.
But under such rules of this plane, being able to cultivate a monster that is the endpoint of evolution every few decades or centuries is enough to prove that this mechanism is well-operated and very effective.
