Reborn: I Took the Demon Venerable as My Little Brother

In her previous life, everyone in the sect regarded Tan Jinyue as a little savior. They were convinced that she had saved Ruan Yuxin, driven off the demon clan all by herself, and brought the sect leader back from the brink of death by refining a Soul-Returning Pill. But Xiao Lan, the one who lured away the Heart-Eating Demon, wagered half her life against the demon clan, and refined the Soul-Returning Pill, had always been a fraud in the eyes of everyone at Cangshan Sect, someone trying to steal another person's place. Fine, then. A fraud it was. Xiao Lan ran her tongue over her back teeth. In this life, she'll save only those she wants to save. As for those fated to die, she'll keep count of every last one of them, so no one can stand in the way of their journey through reincarnation. Xiao Lan levels up along the way and, while she's at it, takes her greatest rival from her previous life as her little brother. Theme: A clever little brother makes his big sister happy. A foolish one gets a good thrashing.
