At the height of the Daduan Dynasty, the three-hundred-year alliance between the Muyun royal family and the Muru family was broken by a prophecy. The prophecy said that if the Sixth Prince Mu Yunsheng held the sword, the world would be in chaos, and Muru Hanjiang would become the future emperor. Local forces represented by Mu Yunluan and Mu Yunde conspired to seize power and cooperate with evil forces for this purpose. Prince Mu Yunsheng did not love the country and did not believe in destiny. He would rather sacrifice power and status in pursuit of true love. Muru Hanjiang was born in a noble family and grew up in the market. He liked freedom and wanted to protect order. After hardships and tribulations, he finally returned to his family. Shuofeng Heye lost his relatives and clansmen in the battle with the Muru Iron Cavalry. After the baptism of blood and fire, the farewell of life and death, the warmth and coldness of human feelings, and the collision of power, he grew from a revenger to the king of Tieqin.
