After transforming into a python snake, the Serpent Musk Granny's head unexpectedly grew two horn-like structures similar to dragon horns.
She resembled more a legendary Dragon Serpent than a python snake.
According to legend, a snake turns into a python, a python into a Jiao, a Jiao into a dragon.
It is an evolution from one stage to another.
But the ancestor of the Serpent Musk Granny, her grandmother, was among the first cultivators.
She created a cultivation method herself.
Transforming directly from a snake into a dragon, skipping other intermediate steps.
Because the inherited technique was incomplete, the Serpent Musk Granny is now stuck in the Dragon Serpent stage.
Unable to advance further, unable to completely shed skin and scale, to ascend the dragon gate from serpent.
Thus, knowing that the Nether King holds the inheritance she needs, the Serpent Musk Granny willingly works for the Nether King.
