In the final years of the Wu Zhou dynasty, the palace walls loomed ominously, with hidden dangers stirring beneath the surface. Princess Yuzhen, Li Chiying, and Princess Jinxian, Li Hua, were living at Yansheng Abbey on Mount Zhongnan, hoping to withdraw from the world, cultivate the Dao, and stay far from court intrigues.
A secret letter shattered their peace. The sisters learned of a long-buried secret: their birth mother, who had supposedly died of illness years ago, and their wet nurse had not perished. They had been secretly abducted and their whereabouts concealed.
To find their loved ones and uncover the truth behind the injustice, the two women cast off the trappings of royalty, descended the mountain disguised as Taoist nuns, and set out into the world, traversing the ancient roads of Guanzhong.
At the ferry crossing at Baqiao, they encountered wandering martial artists and travelers from the Western Regions, and unwittingly became entangled in old grudges spanning the court, the martial world, and the grasslands. Wei Tuan'er’s long-nursed scheme of revenge, the deadly old case of the Black and White Fiends, and the covert surveillance of the palace guards followed one after another.
Two princesses of the Daoist faith wander through a troubled martial world. Amid the fractures of a golden age, they pursue the truth, uphold justice, and remain true to themselves.
