At the end of the Sui Dynasty, the war was raging. Li Zhaoning, a woman who was born in a general family, was not willing to be confined to the boudoir. When her family and country were in danger, she dispersed her family assets and gathered righteousness to raise an army. She recruited heroes, conquered cities, and formed alliances with heroes. With her extraordinary courage and wisdom, she created a prestigious women's army in the land of Guanzhong. The Sui army was defeated in the martial arts field, and the alliance was decided in the Si Zhuyuan. Finally, he led his troops to encircle Chang'an and laid the first cornerstone of the Li Dynasty in a scorched earth.
At the same time, her husband Chai Shao and his father Li Yuan raised troops in Taiyuan, fought bloody battles east of the river, and fought in all directions. The couple established their foundation in Guanzhong and fought hard in Hedong. Thousands of miles apart, they could only send their thoughts and concerns through letters. In the light and shadow of swords, Qingshuang and Qiu Shui's swords are separated, but they carry each other's unreserved trust and trust.
