Transmigrated as the Villainous Empress Dowager, I Teach Seven Brats to Rule the World

Modern career woman Tang Ruyue is in a car accident and wakes up having transmigrated into a book as the most noble woman in the Great Xia Dynasty: the Empress Dowager. Just as Tang Ruyue is ready to lie flat and enjoy her retirement, she realizes that she isn't the kindly old empress from My Fair Princess, but the book's biggest villain. To make matters worse, the emperor is hopelessly lovesick and bent on self-destruction. He is obsessed with his younger brother's wife and plans to get his brother killed on the northwestern frontier so he can run away with her. Tang Ruyue promptly deposes him. A ruler who cares only about his own pleasure and gives no thought to the people's lives is nothing but a waste of air. At least, after his removal, three princes and two princesses remain, so there is still hope. Tang Ruyue rules from behind the curtain, keeps the ministers in line, takes on the chief councilor, pacifies the vassal kings, and receives envoys from tributary states. Her grandsons study history, train in martial arts, go among the people in disguise, and lead armies into battle. Every one of them is a true powerhouse. Together, grandmother and grandsons usher in a century of prosperity for Great Xia.
