I Became the Eldest Senior Sister and Raised the Whole Sect Myself

[No romance + gentle, caring big sister × super-sister-obsessed little brother] Yao Xiao woke up to find herself sleeping in a shabby thatched hut, with her five-year-old little brother lying beside her. They had no parents. She thought she had transmigrated to an ancient rural village and was looking forward to taking her little brother to farm and do business, building a prosperous life for them. Then, without warning, the whole story took a strange turn: somehow, she had started cultivating immortality???

So is this a farming story or a cultivation story???
