After My Junior Sister Turned Sweet on the Outside, Dark Within, She Went on a Rampage in the Cultivation World

(The rating just came out and is a little low. It should go up.) 【Cultivation + ensemble cast + strong female lead + dual cultivation in talismans and swords + romance + satisfying power fantasy】 Shi Jin had always believed she was lucky. The moment she opened her eyes, she found herself with the status of an heir. Then one night, she dreamed that her family had been wiped out. Only then did she realize she was just a pawn in someone else's game. But she was determined to defy fate and overturn the board. Are talisman cultivators just support? Watch her challenge a Nascent Soul-stage demon beast alone, punching above her weight. Is the demon race about to emerge? Watch her drive the demon army back a hundred miles with one talisman and one sword. People disappearing, selfless sacrifices, a ghost city fallen to darkness? The girl set out to shatter the demon race's schemes. Wherever her swordlight passed, darkness would never take root again. When the year her entire clan was supposed to be wiped out finally arrived, Shi Jin realized she'd worked her way up into a powerhouse capable of protecting her family. As for the demon race, always trying to provoke a war, Shi Jin gave a soft snort. The Demon Lord beneath her feet immediately disintegrated into ash. A little skit: One day, Shi Jin charged at the Demon Lord with her sword. The demons around them trembled in fear. Her senior brother, dressed in black, held Shi Jin's sword against the Demon Lord's neck and said affectionately, “Your sword belongs here.” After being corrected, Shi Jin lowered her eyes slightly. Her slender frame seemed so frail that she might collapse at any moment. The demons around them saw a flash of swordlight, and the girl's senior brother decapitated the Demon Lord. Hey, man, are you some kind of bodyguard?
