The Wicked Mother-in-Law Wants to Found a Sect

(No male lead, no romance, female-led cultivation, founding a sect, System-based.) After transmigrating to the world of immortal cultivation, Wu Lele finds herself not only an old woman, but also a notorious shrew of a mother-in-law. She opens her eyes to find her husband dead, then closes them only to be bound to a System. Before Wu Lele can even catch her breath, her two daughters-in-law gather around her unconscious body, looking worried as they discuss selling the family property to bury their father-in-law and pay for their mother-in-law's treatment. If that still isn't enough, they'll have to grit their teeth and send the two girls in the family who are presentable enough to work as maids in the county town. Wu Lele hears this and knows she can't let it stand, so she quickly gets up to take charge. Building infrastructure and farming, founding a sect, Wu Lele leads her two daughters-in-law and her grandchildren in creating the cultivation world's greatest sect from scratch.
