Xiaowei, living in a small border town, disguised herself as a man to make a living and toil in the army. She witnessed with her own eyes female general Hou Lanxue, who had once single-handedly resisted tens of thousands of troops, framed by the emperor and her family wronged, being exiled to the northern border military camp to suffer extreme humiliation, her sanity nearing collapse. Risking her life, she took advantage of the chaos to rescue her, fleeing south all the way. At an ancient temple, she accidentally encountered the founding princess Zhao Huaxi, who had lost power and been abandoned for interceding on behalf of the Hou family. Two tarnished bright pearls and a mortal female physician finally laid aside their estrangement and joined hands in a blood oath to rebuild the old units, purge the emperor's entourage, and wash away the unjust grievances, allowing the tarnished bright pearls to bloom with brilliance once again and protecting the peaceful rivers and mountains of the Heng state.
