Daughter with Plain Hands

A modern intelligence agent travels to an ancient prince's mansion and becomes the second lady. In her free time, she drinks tea with a few friends, makes fun of her, practices martial arts, and treats the house fights as a show. The ministers arrange them as they please. With her own cleverness and calculations, she joins hands with the fifth prince to help the eldest grandson ascend the throne smoothly, and gives birth to three or two little buns to continue their popularity. Then, tragedy strikes, the buns are not obedient at all and are wilder than she was when she was a child. Forget it, she might as well tease her grandson.
