Shen Ci, who was born into a general but whose family was in decline, was selected by the Imperial Palace to marry the prince Xiao Yan as a wedding bride. On the day of the wedding, the prince coughed up blood and fainted, and Shen Ci became a "little one" who could be bullied by everyone. She relied on the archery skills and battlefield wisdom she had learned in the past to resolve the open and secret attacks in the inner house and the previous court time and time again. From being poisoned, framed, and used as a pawn, to exposing the Taishi Mansion's conspiracy to collaborate with the enemy and treason, killing the enemy, clearing out the harem, and finally being granted a first-class imperial title as a woman, she participated in the government. She and Xiao Yan used each other, tested each other, and relied on each other in life and death. They worked together to fight against foreign enemies and quell internal strife. The arrow pointed in the direction.
