The challenges a female cultivator had to overcome on her life journey were countless.

She mustn’t be lacking in talent, cultivation techniques, medicinal pills, and magic weapons. Otherwise, her cultivation would progress too slowly.

She also mustn’t have too many emotions, weaknesses, kindness, and greed. If she had too much of them, she would soon be saying hello with death.
