My Whole Sect Is Full of Laid-Back Villains, Except My Overachieving Junior Sister

After transmigrating into a book, Mu Yunxi becomes the vicious supporting female character in a cultivation novel, the one who steals the heroine's spiritual root and bullies her. To escape the fate of a villain who never survives past three episodes, she sends the original heroine to the greatest sect, while joining the most useless sect herself. She thinks she can keep her head down, but it turns out the useless sect is full of eccentric villains. Her eldest senior brother is always sleepy, her second senior brother is a glutton, her third senior brother loves collecting junk, her fourth senior sister is vain, her fifth senior brother is a lovesick, obsessive type, her sixth senior brother is always acting cute, and her seventh senior sister is a total social recluse. She thinks they're all good-for-nothings, never realizing they're secretly big shots. Mu Yunxi feels the pressure and can only throw herself into training. Somehow, she ends up the sect's most beloved disciple!
