Am I Really Not the Chosen One?

Siblings’ Blurb: Yu Yao transmigrates into a fantasy world and becomes the younger of the Yu family’s twins. On the day she is born, dragon energy descends from the heavens, and every koi fish dies. It’s either a great blessing or a great disaster. Yu Yao: QAQ, I think I’ve seen this episode on TV. Unfortunately, she’s the great disaster. The Imperial Preceptor declares: “Twins of yin and yang, destined to strengthen and counteract each other. The eldest son bears the mark of an emperor, with a sword bone from birth.” As for her... she has a useless bone, is born unlucky, and will even affect her brother’s fortune. Yu Yao clenches her tiny fists: “So many people transmigrate, so why didn’t I get the script of a peerless hero?” But the Imperial Preceptor’s words can’t be ignored. The head of the Yu family steels himself and tries to send his daughter away, but fails. The reason? The genius older brother, who hasn’t cried or fussed once since birth, wails the moment he is separated from his sister. He cries so hard the heavens and earth shake, his voice hoarse and breaking. As if he’s about to cry himself to death. From then on, wherever Yu Miao goes, he wishes he could tie his little sister to his side and protect her. “You’re my only sister. In this world, other than Mother, I’m the only person who will never hurt you.” But later... The sense of fate pressing in arrives quietly. The siblings face each other in battle, standing on opposite sides, both fighting with murderous fury. Yu Miao hates her to the core and repeatedly demands in a chilling voice, eyes red, “You were the one who betrayed me first. Even if everyone in the world were dead, you should still have stood with me!” “Our world should have been just the two of us! You were the one who betrayed me first!” Male Lead’s Blurb: After putting an end to the wars across the Nine Provinces, Li Fuzhou, the greatest Sword Immortal of his generation, faked his death and disappeared for two hundred years. He became a snow-sweeping disciple on Mount Kunlun, spending his days with wine. Fame and fortune were like passing clouds to him; all he wanted was a carefree life. Then one day, a young woman fell from the sky, wrecked his grove of white plum trees, and tore his home apart. She had a useless bone in her body and the nerve to declare that she would become the second Sword Immortal of the Nine Provinces. He scoffed. Yu Yao was furious. “Don’t underestimate me! Once I join the inner sect, I’ll teach you swordsmanship.” What a joke. Li Fuzhou laughed so hard he nearly cried. “Sure. I’ll be waiting.” Who could have guessed that later... He would cut out his own bone and offer it to her, feed her with his blood, and beg only for the dying girl, who had lost all will to live, to light up her eyes again and declare to him once more, full of youthful spirit: “I’m going to become the second Sword Immortal of the Nine Provinces!” / Reader note: A low-martial fantasy setting, with the worldbuilding serving the plot. The heroine has character growth, family bonds, friendships, and romance. The siblings’ relationship is familial, not romantic, but plays a major role. Theme: Be yourself
