The rating has only just been posted. It will rise later. [Devoted Couple + Sickly, Scheming Green-Tea Villainous Husband + Four Blackened Children with Distinct Personalities + All-Powerful, Strong Female Lead Skilled in Medicine and Poison] A stunningly beautiful poison doctor transmigrates into a novel as a wicked, fat village girl in a fictional historical era. Her original self was doted on by her family, grew up fat as a pig, possessed immense strength, and was the local bully for miles around. She was always ready to take a swing at her husband and beat her children. Having transmigrated into a book, she knows her husband will eventually ascend to the throne, then have their four children hack her to pieces. From the start, it's a living hell, and the System wants her to reform this whole cast of major villains and turn them into upstanding people?! Shu Wanyue eyed her sickly, helpless husband, whose eyes glinted with malice, along with the fierce little brats standing in front of him. She felt completely overwhelmed. These were the ultimate villains in the book. How could she possibly handle them? Fortunately, she had access to a Pinduoduo space where she could buy anything! She went hunting in the mountains and became a legendary hunter. She went into business by the sea and became the biggest profiteer. She swore she'd gradually cure her sickly husband's and the children's yandere tendencies! Years later, Shu Wanyue had become the wife of the Chief Councillor. As she looked at the fifth baby in her belly, a dazed look crossed her eyes. Damn it, she'd fallen for that yandere's trap again without even noticing!
