After Becoming Cannon Fodder, I Shocked the Cultivation World

[Strong female lead + satisfying read + adored by all + ensemble cast] Shen Que was walking along when a System fell out of the sky and hit her, sending her straight into a novel. She became the protagonists' frail, sickly junior sister, gifted with extraordinary talent but destined to die young. To stay alive, she accepted the missions issued by the System. The protagonists in the book all perish due to uncontrollable circumstances, and their deaths cause the small worlds to collapse. Shen Que's mission is to save them and prevent the worlds from falling apart. Word has it that the leader of the Tianxuan Sect has taken on a young disciple, a sickly girl who is not long for this world. Everyone thinks she will die soon, but no one expects that not only does she keep surviving, she also manages to lead the entire sect astray all by herself. And so the cold, aloof eldest senior brother, who had set his heart on becoming the supreme swordsman, turns into the sect's resident househusband; the second senior sister, a workaholic and the leading alchemist, becomes a couch potato; the innocent and guileless third senior brother becomes a wily old fox skilled in every kind of scam; and the kind, adorable fourth senior sister becomes someone who draws her blade at the slightest provocation... Help! The whole sect has gone completely off the rails. Everyone thinks she is just a delicate, sickly beauty, pampered and protected by all, until one day the demon race invades. The defenders fight with all their might, but it is still no use, and the city is about to become a living hell. Just as everyone falls into despair, a figure descends from the sky, sword in hand. One strike shatters ten thousand techniques and shields everyone from harm. Only later do they learn that the figure was none other than the frail little junior sister of the Tianxuan Sect. The young should aspire to reach the clouds. It turns out she, too, once wielded her sword to save all living beings, and once sent a sword's icy chill across fourteen provinces.
