So What If I'm Shameless? The Big Shots Are Fighting to Make Me Their Daughter

[Leveling-Up + Ensemble Cast] The System binds itself to a Host, but an accident during transmigration turns the Host into a two-year-old child, and a complete idiot to boot!!! The System coaxes and tricks the Host until she finally regains her memories, only to discover that she's a total slacker!!! System: I'm tired. So it starts slacking off too. But as it slacks, it somehow watches its Host go from a sinner's daughter to the Demon Venerable's goddaughter??? Then, while still slacking, she becomes the Immortal Alliance's heir-apparent??? And finally, she becomes the savior who rescues the world??? System: Holy crap, she's incredible. * Nan Fu's father is a sinner who betrayed the righteous path. Her mother is missing, and she has only her older brother to rely on. She thought she could live a quiet, peaceful life and watch her brother grow up safely, but fate separated her from her family. Nan Fu clenches her fist. “To find my dear brother, I guess I'll just have to become the greatest under heaven!” Other chosen prodigies: “Hey! Are we invisible to you?!” The chosen prodigies, after getting beaten up: “Sure, just pretend we're not here.” Before long, more and more underlings gather behind her, and even the original novel's overpowered male lead accepts her as his boss. Nan Fu, now the greatest under heaven: “Then I might as well save a world while I'm at it!” [P.S. The heroine isn't a flawless paragon of virtue. She has a low sense of morality.]
