When the country is ruined and the family is in ruins, should you cling to the old dream of a boudoir with red sleeves and add fragrance, or should you hold a sword and wear armor and use your daughter to control the border thousands of miles away? Su Yunheng was originally a gentle and scholarly girl, but due to the turbulent times, she took off her skirt and rode on the battlefield. Her first love ended in war, her ex-husband betrayed her, and she was scarred all over. She met Xin Yiyong, the legitimate son of the Hou family - this stingy iron rooster turned out to be a hidden star on the battlefield! Ignoring secular prejudices, he strongly recommended her as a major general and helped her rise to the rank of commander. From the use of mutual temptation to the tacit understanding of life and death, the two tempered their bones in the bloody battle at the border and held hands in the secret fight in the court. The old love died, the old friends turned against each other, and the powerful officials forced her into the palace. She finally realized that a woman's destination was never to live in a deep house in a courtyard, but to share military talisman and protect mountains and rivers with her husband. When the smoke clears, will she be a powerful female leader, or will she join hands with him to see the prosperous Chang'an together?
