The Cannon Fodder Sister of a Fake Young Master [Goofy]

As a powerful cultivator, Shi Ge suddenly transmigrated into the older sister of a fake young master, a cannon-fodder character, and was bound to a System. Though this is a story about a real and fake young master, it has nothing to do with her. According to the plot, her gambling-addict father is about to sell her off. She won't even live long enough to see the truth about the young masters revealed. Shi Ge looked at the two men already haggling over a price, grabbed her scumbag father, and asked the other man, "Will you take him for five hundred?" The man looked delighted. "Deal!" Her father immediately objected. "No way. I won't sell for less than fifty thousand!" Shi Ge couldn't be bothered to waste time talking. She knocked him out, shoved him into the man's arms, and said, "He's yours. Pay up." The man: "???" Lady, are you crazy, or am I? The System stared in shock at her counting the money and hurriedly spoke up. "Boss, selling people is illegal here!" Please be a law-abiding citizen! Shi Ge: "..." What a hassle. Shi Yue was reborn. For the first sixteen years of his life, his gambling-addict scumbag parents had tormented him. At last, he discovered he was the real young master, but returning to that family only made him feel more suffocated. His parents were distant, his older brother hated him, and his classmates ostracized him, as if being switched at birth were his fault and he shouldn't have returned. They thought he had stolen Jiu Yue's place. But it had all belonged to him in the first place. Shi Yue swore that in this life, he would take everything that was his back! But something seemed a little off! Shi Yue got a call from the police station: "???" What? What do you mean he has to come bail someone out? Huh? His sister is selling off their scumbag father??? Reader's guide: 1. A strong female lead and comedy. The male lead is strong too, but doesn't realize it. 2. A heroine with top-tier combat skills who isn't very familiar with modern society x a beautiful, strong, pitiful real young master. 3. The older sister is only one year older than the real young master, but the female lead is much, much older. They did not grow up together, are not on the same household registration, and are not related by blood. The older sister was raised by her grandmother from childhood. [The blurb has been slightly revised, but the story is still a strong-female-lead comedy.] Theme: A happy life
