The bluestone is crossing the wind and the sand is filling the sky, Yan Wuchen is sweeping the yard and feeding the chickens. No one knows that he is the martial arts master Mo Wen who has retired to seclusion. A wandering girl, A Ruo, makes a living by stealing steamed buns, and the fire paint mark on her palm hides the mystery of her life experience. The world is once again in turmoil due to "Xuanshu Fragments", and three major families and seven sects gather in the town. The Rusty Sword Monument moves abnormally, the fragments of the scroll appear, and A Ruo accidentally triggers the sword box to identify its owner. Yan Wuchen was forced to take action, fought back the enemy with one sword, and took Aruo on the road to find the scroll. The two of them walked along the Huangsha Ancient Road, the Water Country and the Secret Land of the Ancient Temple. She is more amusing than a drama queen, but he is silent and protective; her palm prints lead to secrets, and his sword strikes the world. From the border town to the imperial city of Jiuchuan, the fragments are put together, and the peak of martial arts is finally revealed. As the last hairpin fell from my hair, the donkey cart drove slowly away under the setting sun.
