I Transmigrated Into a Book Set in the 1970S and Became a Woman Who Abandoned Her Husband and Child

When Jiang Xianli opened her eyes, she had become the cannon-fodder supporting female character in a period novel. In the book, she was a heartless woman who abandoned her husband and child, the very definition of vanity and callousness. She paid a terrible price for her cold-heartedness. Her younger sister was practically her exact opposite. When Jiang Xianli abandoned her husband and child to marry into a powerful family, her sister volunteered to go to the countryside and followed her brother-in-law far away to the southwest. She took care of his daily needs, eventually won his heart, and became the true winner in life. After transmigrating, Jiang Xianli had only planned to steer clear of trouble and live a quiet life of her own.

To stay alive, Jiang Xianli traveled all the way to the southwest and diligently set about breaking them up. But as she carried on, why did her ex-husband's gaze grow more and more heated?
