In the winter of the twenty-seventh year of Yong'an, Su Jintang, the legitimate daughter of the Duke of Zhenguo, stands in the wedding hall in her phoenix crown and red bridal robes, only for her new husband, Xiao Che, to tear out her heart with his own hands. Until her dying breath, she cannot forget how she poured the strength of the entire ducal household into helping him rise from a lowborn officer to a great general, only to be repaid with the execution of her entire family. The “victory reports” claiming that her father and brothers died in battle were lies; Xiao Che fabricated the charges of treason, and he had even bribed her personal maid to steal the military command seal her mother left behind, granting authority over a million troops.
As blood splashes across the wedding hall, Su Jintang swears through her tears that if she gets another life, she will make those two wretches pay in blood!
When she opens her eyes again, she has returned to the eve of her fifteenth-birthday coming-of-age ceremony. Her father and brothers are alive, the ducal household still stands, and Xiao Che is still the down-and-out officer who needs her “support,” arriving at her door with a hypocritical smile to ask for her hand.
In this life, Su Jintang puts away her innocence and hides her tenderness, becoming a fierce wife with a blade in her hand. She tears up the engagement and crushes Xiao Che's treacherous ambitions before they can take root. She trains hard in horsemanship and archery, making a name for herself with a single arrow at the imperial hunt and earning the admiration of the capital's noblewomen. She takes charge of the household, exposes the spies within, and protects the foundations of the ducal estate. In secret, she also contacts her mother's former subordinates and keeps the military command seal firmly in her own hands.
When Xiao Che once again tries to climb the social ladder through her, she regards him coldly and sends him plummeting into the abyss. When the white-lotus cousin who betrayed her in her previous life tries the same old tricks, Su Jintang moves carefully at every turn until she is ruined. And Lu Jinghan, the Marquis of Zhenbei, who barely crossed paths with her in her previous life but secretly helped when her family fell into calamity, begins appearing before her again and again in this life
