Graceful as a startled swan, brilliant as a roaming dragon, darting back and forth amidst a crowd of Head-falling Ba; now in front, now suddenly behind, her figure as enchantingly graceful as a Banished Immortal descending to earth, akin to the Mysterious Lady soaring to the heavens. Regardless of how the Head-falling Ba hordes tried to surround, outmaneuver, block, and assail her, they couldn't even touch a hem of her garment.

Every Sword technique she spawned involved numerous variations, with each variation eliciting a meticulously and prudently predicted response.
