Shattered Stars as Blades

She was once the Sword Master at the top of the Nine Heavens, but fell and became a low-ranking disciple of Waste Spiritual Root. The sect regarded her as a shame, and her fellow disciples laughed at her for wishful thinking. Until she picked up half a rusty sword in a forbidden area. Inside the sword lived a weapon spirit that only knew how to curse. The weapon spirit said: Your sword's heart is broken, but your bones are still strong. From then on, she used broken stars as blades to kill the gods, kill immortals and Buddhas, and made the entire world of cultivation kneel down to listen to her reasoning.
