Heaven's Gift: A Brother and Sister Brave the World of Cultivation

(Mostly everyday life between an older sister and her younger siblings, with a focus on family and supporting one another. No romance. The younger siblings are just a tiny bit more talented than their big sister~) After leaving the orphanage, Yu Zhouwan works hard to earn money and give back to the orphanage. She also plans to buy herself a little place of her own. Just as she's about to make the down payment, she suddenly drops dead and transmigrates to an unknown world, where she becomes the older sister of three poor children. Eldest brother Yu Zhenyue: "Sis, if anyone bullies you, I'll chop them up." Younger sister Yu Zhenyan: "Sis, if anyone insults you, I'll poison them mute." Youngest brother Yu Zhenmo: "Sis, if anyone steals your stuff, I'll smash them with my spirit weapon." They happily set off with their siblings to the cultivation world to find their parents. But the cultivation world is in ruins, and they end up saving it by accident!
