At the end of the world, the building will collapse. When the news of the death of Marquis Jing'an came, the legitimate daughter Shen Jinghong, dressed in plain clothes, took over the commander's seal in the wind and snow. She took off her red makeup and returned to the court as a man in the name of her brother. In the court, she fought with the scholars; on the battlefield, she fought bloody battles in all directions. When he, a sickly lone wolf, met her, a lone wolf in flames, who would win the chess game? As recorded in the history books, is it a tragedy repeating itself or a reversal of events? In this life, she does not believe in destiny, but only believes in the three-foot green blade in her hand, vowing to fight for a way out of this broken mountain and river!
