It would be impossible for a ginseng spirit with divine blood to live for ten thousand years in a low-level world. It wouldn't even survive for a thousand years as it didn't have enough spirit qi for it to grow.
Even in a middle-class world, finding one that'd lived for ten thousand years was rare.
Even if a large sect were to try and cultivate one in their own herb farm, it was rare for them to wait for the ginseng to grow for a thousand years. For one to reach the ten thousand years mark, at least ten generations of Consolidation Realm cultivators would have to tend to it before the sect could use it.
Thus, the chance for one to reach ten thousand years was rare. It was even rarer for one to actually take a form and began cultivating. The probability for that to happen was like a man winning a five million lottery after playing for an entire year without stopping.
