The Demon Venerable Reborn as the Righteous Sect's Beloved Junior Sister

Su Mengbai was a bold, carefree Demon Lord. Then, one day, everyone turned against her. The righteous sects plotted to surround and kill her, and she ultimately died by Xie Qingshi's sword. When she opens her eyes again, she discovers that she's been reborn as the newest and last disciple Xie Qingshi has taken in. Her new body isn't strong enough yet, so she decides to keep a low profile until she breaks through, then get revenge for her own death. While she's at it, she'll deceive Xie Qingshi into falling for her, become his favorite little disciple, and torment his other disciples one by one. Then, just before killing him, she'll strike him with a fatal blow: "Surprise! Your favorite little disciple is actually the Demon Lord." The script is all set, but the story's taking a wildly unexpected turn... Her eldest senior brother hits a bottleneck, so Su Mengbai gives him a cultivation manual that will send anyone who practices it into a demonic frenzy. She smiles sweetly. "The manual Master gave you is wrong. Try this one." Her eldest senior brother takes the manual and makes incredible progress in his cultivation, even grasping a new sword intent. There's not the slightest sign of him going into a demonic frenzy. Eldest Senior Brother: "!" Su Mengbai: "!?" Her second senior sister and her Dao companion are living happily together, so Su Mengbai severs his tendons and meridians, turning him into a cripple. She plans to blame Xie Qingshi when her second senior sister comes looking for an explanation. With red-rimmed eyes, her second senior sister comes to see her and pulls her into an embrace. "How did you know he betrayed me? I hate him so much..." Su Mengbai: "???" Her third senior brother is suffering from a deadly poison, beyond the help of any medicine, so Su Mengbai brings him a newly developed poison to test. "You're doomed anyway. I'm going to use these poisons on Xie Qingshi later, so I'll test them on you first." By some twist of fate, the poisons counteract each other, and her third senior brother's health improves day by day. Su Mengbai: "..." There's something wrong with this sect. - Later, Su Mengbai's identity as the Demon Lord is exposed, drawing the righteous sects down on her once again. Su Mengbai leisurely toys with the knife in her hand, wondering whether to kill all these so-called righteous sects first or Xie Qingshi. But her senior brothers and sisters are still smiling and chatting as usual. Her eldest senior brother shields her. "Little Junior Sister, stay behind me. No one can lay a hand on you." Her second senior sister hands her a skewer of candied hawthorns. "Don't be scared. Once you've finished eating, we'll go release lanterns." Su Mengbai refuses their kindness, presses her knife against Xie Qingshi's neck, and smiles mockingly. "How about I kill you first?" Xie Qingshi smiles, serene and radiant, and gently strokes her face. "Want to be a pair of lovers on the run with me? That's fine. Let me kill them all first, then I'll die with you. How does that sound?" Su Mengbai: "?" I thought they were supposed to be righteous sects. Why are they even crazier than me? (Written on 2022.5.9.
