The Kurong Mountains have been dead for three thousand years, and the wind carries a rotten smell.
When the village doctor A Wu walked into the dead place carrying a medicine bag, even the vultures refused to peck at her.
She was not a fairy, she had no fairy bones, she only had a polished silver needle, half a gourd of bitter herbs, and a red-horned bull that lowered its head to let her ride on its back when she was in the most miserable state.
People in the world practice immortality, seeking immortality, cutting off love threads, and transcending reincarnation.
Only the woman who smelled of medicine leaned on the warm cow's back, looked at the falling heaven and earth, and said softly: "Wherever there is disease, there is medicine."
Later history books were vague and only recorded one sentence: mortal bones will not fall, medical skills will live forever.
And the old cow that had carried the world on its back guarded the stone eggs for a thousand years after she transformed into a Taoist.
Intention: Replace traditional killing and upgrading with "healing earth veins/healing the way of heaven". The dual power of medicine and poison is chaotic and tolerant. Mortals without spiritual roots can enter the way through medicine.
