After Failing My Tribulation, I Reincarnated as the True Heiress

[Metaphysical cultivation + silly humor + phoenix-like heroine + no romance] A mighty cultivator and the strongest member of the human race, she possessed a divine fire of her own, the Red Lotus Karmic Flame. As she was about to transcend her tribulation and become an immortal, the strongest members of the demon race attacked en masse, and she tragically perished. She was reborn and found and raised by her grandparents. After awakening the memories of her past life, she lived alone in a small mountain village until her biological parents found her and brought her home. Her biological parents doted on her. The twins in the family were a little dim-witted. A few more beatings should sort them out. As for the fake heiress who took her place, she was a lovesick, airheaded sweetheart. The classmates she met at school were a pair of hopeless goofballs: the one with good grades pretended to cheat, while the one with bad grades secretly worked hard. Little by little, she learned the secrets of this world. The King of Hell in the underworld and the Azure Emperor of the demon race turned out to be her underlings.
