Reborn as an Immortal Vine

A beauty dreams for three thousand years, while wielding a sword on the path to immortality. When she awakens from the dream, she is once again standing before the old building in the mortal world. A dream? Reborn! Her mother is gravely ill, and her brother is a wastrel. They must be cured! Su Xian can only stare blankly. Where is the young lady's immortal vine? Ahem, beautiful senior brother, weren't you supposed to ascend early and become an immortal? P.S. A story about a cannon-fodder who transmigrates into the cultivation world and is then reborn back in her original era. Household intrigue plus cultivation, a lighthearted show to enjoy, with the vile ones getting their due.
