Sisters Transmigrate: My Big Sister Is a Cat

[Cultivation + dual female leads + doting senior sister + sweet and angsty romance] [Angst, angst, angst in the middle. A 40-meter blade, dipped in sugar.] The aloof senior sister's eyes turn red. “Are you going to leave me again? Please don't go, okay?” The aloof, alluring eldest senior sister, a tall woman with long, straight black hair + the innocent junior sister who falls for her without hesitation (she'll find her backbone later and devour the eldest senior sister) One day, An Ran wakes up to discover she's transmigrated, and her older sister has turned into a little cat. She sets off on the path to immortality, searching for a way to turn her sister back into a human. But why does this aloof eldest senior sister keep flirting with me? I just want to cultivate, okay?! Later, a misunderstanding drives them apart. An Ran falls into the endless abyss and suffers terribly, while her senior sister is consumed by regret… An Ran has always thought she was the protagonist, the chosen one. But one day, a man shows up claiming he has a script and that he's the male lead. He says An Ran has stood in his way, stolen his opportunities, and taken his eldest senior sister. An Ran is stunned! Huh? This world has a script? How come I don't have one? Where's my System? Where's my golden finger? My fate is mine to decide, not heaven's. An Ran refuses to accept her lot. She'll turn the plot around and trample the male lead underfoot. Warning: No male lead! No male lead! No male lead! Important things must be said three times. The so-called male lead is cannon fodder. He's a nuisance early on and gets killed off midway through. Angst, angst, angst in the middle. A 40-meter blade, dipped in sugar. The cat-sister returns later, and it ends with a happy ending as they settle down at Qinglan Sect
