Yun Shu, the legitimate daughter of the Beihou Mansion in Beijing Zhen, mistakenly believed in Duan Wang Xiao Che in her previous life, and used the family's military power as bait, which resulted in the tragic ending of having her entire family executed. Once she was reborn, she returned to the time when she was seventeen years old and unmarried. Her bloody memory was engraved in her bones, and she vowed to protect the Yun family and the Yanmen Mountains with her flesh and blood. Faced with Xiao Che's false proposal for marriage and the Liu family's increasing pressure, she saw through the poisonous plot, cleverly set up an ambush, and first showed her edge in the shadow of swords; she met the mysterious King of Ember Xiao Jin, and the two went from testing each other to temporarily forming an alliance, but she didn't know whether this cooperation was salvation or a deeper trap. At the Queen Mother's birthday banquet, she exposed the conspiracy of forging military defense maps in public and turned the tide; amidst the undercurrents in the court and the smoke in the north, she used her red armor as armor and wisdom as a blade to wash away the grievances of her previous life while dealing with all forces. This is a game about revenge and protection, and it is also the path to nirvana that a reborn legitimate daughter walks through in the whirlpool of power and intrigue, between the righteousness of her family and country and her personal destiny.
