Traveling Through Troubled Times, I Had No Choice but to Become an Immortal in Order to Protect Myself.

[No system + slow heating + sexual transformation] Travel to a crumbling Zhou Dynasty, where people are in dire straits and wars continue. Lu Nanhua discovered that she was actually a girl, and was about to run away in order to protect herself. By chance, she met an immortal from the upper world, and was forced to become an immortal. In the process, Lu Nanhua's own secrets became more simple and confusing. In order to solve her own problems, in this strange world that is about to collapse, how can she save the world with her female body? (If you are advised to read about male-to-female slow-motion stories, be careful! The heroine in the story has a harem, and the heroine will only marry but not marry, focusing on her career. Please feel free to eat it.)
