A modern urban planning designer, dressed as a noble daughter who was abandoned by her family and sent to a bitter cold place. Facing the devastated border, she did not cry for help. Instead, she took out drawings and led the border people to open up wasteland, build cities, and engage in trade. When the enemy's cavalry pressed on the border, the three-dimensional fortifications she designed made it difficult for the enemy to move forward. The prince's husband, who was said to be decisive in killing but dormant due to old wounds, initially regarded her as a nuisance. Later, when he saw her fingers on the sand table and her oars being wiped out while talking and laughing, he just wanted to lock her tightly to his side and control the country together.
