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.

Moreover, she must look neither too pretty nor too ugly. Although she mustn’t be stupid, she also couldn’t be too intelligent.

Being a female cultivator, Mo Tiange naturally had to face those challenges. Nevertheless, being orphaned from a young age had toughened her tenacity and resilience.
