Killing a human was a difficult task for the Heaven Purple Yang Ginseng.
Spirit herbs were different from desolate beasts, as they had innate deficiencies.
When a herb cultivated itself into a primordial herb or immortal herb, it could not escape its fate of being picked or captured despite its extended lifespan.
Some primordial herbs were even inferior to the Heaven Purple Yang Ginseng. Even as a primordial herb, they had no ability to escape through water or land, they were just sitting there waiting to be picked by humans or eaten by desolate beasts.
Such herb species had little chance of turning into a primordial herb.
Unless these herbs grew in really hidden locations and they were never found by humans, only then would they have the ten thousand years needed to absorb the Heaven Earth essence.
