And now, their fate is sealed as food, but for Klaus, this is just the beginning of his adventure. In a cruel world where people will do anything for power and immortality, he is already very strong and immortal, so what's left if not start a family and have fun stepping on arrogant people through the way?

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.

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. Neither having what were deemed as waste spiritual roots nor limited resources could deter her spirit. Staying as inconspicuous as possible but never let an opportunity go was her daily life.
