The Immortal Path of the Ice Inkstone

[Male soul transmigrates into a woman + gender-bending cultivation + protective master and disciple + demon brother watching over her in secret + one-on-one, both pure]

A paralyzed orphan from Blue Star has her soul transmigrate into Su Qingyan, a cultivator of the pure ice spirit root in the Qingyun Sect, just as undercurrents of gender-bending turmoil begin to stir within the sect. Relying on the mind she forged in her previous life, she cultivates the Ice Sword to survive. Fortunately, she has a fiercely protective master sheltering her from harm and a brother who shares both righteous and demonic nature by her side. She also meets Xie Linyuan, a cultivator with a pure yang spirit root whose strength is always half a stage above hers and who has eyes only for her, indulging her wishes at every turn. From a cold and indifferent nobody on the sect's fringes to the Frostpeak Immortal who rises to prominence, she and Xie Linyuan choose each other and walk hand in hand toward the Nascent Soul path to immortality.

[A steady rise from underdog to powerhouse + sound logic + everyone protects the heroine]
