Under the solitary smoke of the desert, the exiled young man Lu Zhao clutched half of a blood-stained silk fragment. Behind him was the burned-down post station of his homeland, and in front of him was the dead road stretching thousands of miles across the yellow sand. Hu Qi's iron hooves trampled the cities of the Central Plains to pieces, and he glimpsed the vitality in the camel bells of the Western Regions caravans - the "Waterway Map of the Western Regions" concealed the military lifeline that could turn things around. After rebirth, Lu Zhao carried the memories of his previous life and his ghostly cultivation, from the secret passages of the Dunhuang Grottoes to the Samarkand Treasury. He reconstructed the thousands of miles of trade routes with his left hand, and cut off the enemy's food supply with a knife in his right hand. At the same time, Princess Murong Xue, who died unjustly in her previous life, was reborn in the palace. She transformed from the innocent "White Lotus" into the scheming "Black Lotus" and used her prophetic abilities to lay out a revenge chess game in the court. Two roads of revenge intersect on the Silk Road. One uses business roads and ghost roads to weave an iron-blooded network, and the other uses machinations and wisdom to subvert the court. When Lu Zhao's caravan Tuoling met Murong Xue's palace intrigues, they discovered that the same black hand was behind the tragedy in their previous life. After ten years of planning, once the war broke out and reached the gates of Bianliang City, the civil and military talents of the entire dynasty were shocked to realize that the exiled little interpreter and the deposed princess had already used business and ghost ways to weave a web of revenge that enveloped the entire north.
