After Binding to a System, the Wicked Mother-in-Law Makes It Big

Ming He transmigrates into a book, becoming a notoriously wicked woman. The System orders her to complete missions according to the plot.

She has to be mean and vicious, torment her daughter-in-law, turn her son against her, and drive her two sons to become sworn enemies.

She follows the plot and devotes herself to being a wicked mother-in-law. But, bafflingly, life only gets better and better: she becomes fabulously wealthy, the family lives in harmony and peace, and even her two cannon-fodder sons rise to the highest ranks of government and earn her a first-rank imperial title.
