Shen Ninghua, the legitimate daughter of a general, was framed by her relatives and her entire family was executed. In order to avenge the bloodshed, she disguised herself as a man under the name of "Shen Qingci", a poor student, and lurked in the Imperial Academy. With her military prodigy and secret agency skills, she rose to prominence and stepped into the turbulent court.
She won the imperial examination, made meritorious service at the border, and made a counterattack from a poor family to become a general who ruled the country. However, she was fatefully entangled with the cold-faced regent Xiao Jue in the maelstrom of power and intrigue. He is the brother of the late emperor, he holds a lot of troops, and he is also his brother's best friend. He has long seen through her daughter's body under her brocade robe, but he gradually develops feelings for her through temptation and protection.
Secret arrows in the court, wars on the border, and identity crises follow one after another. She not only has to hide her true identity for revenge, but also has to choose between the justice of her family and her personal grudges. When the shocking secret of the Lantern Palace Banquet was exposed, and when her daughter's identity was revealed in front of thousands of troops, she used the blood of loyalty and the courage of a woman to team up with Xiao Jue to expose the shocking conspiracy to poison the late emperor and collude with the vassal king, and avenge the injustice of the Shen family.
The brocade robe fades away, revealing the beauty and pride; protecting each other with swords reveals the deep roots of love. In the end, she took charge of the military in the name of the female general who ruled the country, and joined hands with the regent to assist the new emperor. In troubled times, they kept the country safe together, creating a legend of iron blood and tenderness.
