After Moving to the Countryside, I Use the Sign-In System to Help My Sisters Thrive

Synopsis: [Period setting + Reborn + Educated youth sent to the countryside + Sign-in System + No vilifying the original female lead + Passerby A + Cannon-fodder supporting female character] This book is also known as "Sisters of the Era: Never Dividing the Family" Before Wen Xi was reborn, she learned that the world she lived in was a novel. But she was not the female lead, only a passerby A with few scenes. When the family was away, her biological older sister signed her up to go to the countryside. Two years later, she joined forces with her brother-in-law to trick Wen Xi into returning and marrying an old man, becoming a stepmother, raising children, and serving a difficult mother-in-law. She died before turning thirty. Her best friend Shen Jiaojiao was first deceived into sleeping with the male lead's brother, then abandoned by him. She later married a male villager, but her life was far from good. Another best friend, Jiang Yue, was manipulated by her roommate into marrying a good-for-nothing from the village, whose entire family treated her like an ox to be worked to death. Reborn on the train bound for the countryside, Wen Xi bonded with a sign-in System. Whatever she wished for in her heart, she could sign in and obtain. In this life, she would live well together with her best friends. She would decide for herself whom to marry and whom not to marry.
