My Sword Sect's Favorite Younger Sister

Fufin, a chaotic spirit cultivator with half-demon blood, flees from the resource-scarce Demon Realm to join her biological mother in the Cultivation World. Rejected by the top sect Qingyun Sect due to her apparent five-element root, she is taken in by Tianjian Sect, a powerhouse with immense combat strength but poor finances. The sect's senior disciples are all top-tier sword cultivators who possess legendary swords yet live in caves on simple meals. Fufin, possessing a rare chaotic spirit root and a demonic aura that intimidates all beasts, boasts cultivation talent unmatched in both realms.
