I'm the Adored Junior Sister: So What If I'm Arrogant?

Ji Wushuang was the Undying Sword Venerable feared by both gods and demons, but her closest kin betrayed her, leaving not even a corpse behind. Reborn, she finds herself in the body of a little good-for-nothing whose spiritual bones were stolen and who cannot cultivate. So what if she's useless? She's still the precious darling of her masters! But when she looks closer, she discovers that her masters and fellow disciples are all “nourishment” for the children of destiny. Her first master's grand-disciple is brilliant, peerless in medicine and poison, yet gets deceived by a scumbag and has her spiritual roots destroyed? Her second master's descendant is stunningly talented and kind-hearted, yet a witch tricks her into becoming a cauldron, leaving her dantian shattered and her life extinguished? Her third master's disciple is still a simp even after reaching the Mahayana realm, only to end up with nothing? And the heirs of her fourth and fifth masters... Every one of them meets a worse fate than the last! They give away spiritual treasures, then opportunities, and then even their lives?! Ji Wushuang laughs in a fury, rolls up her sleeves, and sets out to save and teach the kids. If one slap doesn't knock some sense into them, she'll give them several more. She's not afraid of killing them, either. There are people waiting for us in the underworld anyway. In the end, all the prodigies of the Five Great Immortal Sects are reborn from the ashes, each a decisive killer who dazzles the myriad worlds! As for their useless little junior sister, she becomes the only true treasure, and big shot, across all the worlds.
