Charles originally intended to avoid provoking the red-clothed female ghost and tried his best not to provoke her.
Among the vengeful ghosts, the red-clothed female ghost was one of the top-ranked.
Only those who had experienced extreme injustice in their lives, accumulating resentment over time, and nourishing themselves with malevolent energy for over a hundred years had a chance to evolve into a red-clothed female ghost.
All these steps had to be fulfilled for the transformation to occur.
And the probability of success was not high. Perhaps only one in a hundred would succeed.
These details were recorded in the ancient Chinese medicine book that Elder Hall gave to Charles.
As for why there were records of monsters and ghosts in ancient Chinese medicine books, the main reason was that in Chinese medicine, all things could be used for medicinal purposes.
