Why Am I Cannon Fodder When I Outshine the Heroine in Every Way?

Born with a legendary water spirit root, daughter of sect elites, and a Golden Core cultivator at sixteen—she should be the protagonist. Instead, she's the doomed villainess fated to die by the male lead's sword. Armed with knowledge of the plot after transmigrating into this cultivation novel, she plans to avoid the heroine and focus on her own path to immortality. But when the so-called protagonist keeps trying to 'conquer' her like some NPC side quest? Game on. No one—not fate, not the heroine, not even the story itself—will stand in her way.
