Three years ago, the Huo family's treason case was shocking. Xie Zhaoyi of Qingwu Palace passed away unexpectedly. The prince of the East Palace lay dormant and a severed finger was hidden in a bronze coffin, which became a blood contract that no one knew about. Three years later, Huo Mingzhao returned with clues about the ring pattern. Just as the Yanmen Iron Cavalry was approaching, the water transportation in the south of the Yangtze River was in chaos, and the mysterious Mandala organization took Qingwu Palace as its name and stirred up the world.
Standing side by side in the wind and snow of Yanmen, protecting each other in the deep alleys of the palace walls, Huo Mingzhao and Xiao Che joined hands to quell the chaos from the south of the Yangtze River to rush to the north to help, from the undercurrent in the court to the appearance of the shadow master. What they uncovered layer by layer was not only the grievances of the Huo family and the secrets of Qingwu Palace, but also a world-wide chess game that spanned three years. With the blood contract as proof and the tiger talisman as evidence, they use their swords to defeat the plot and stick to their hearts, hoping to finally bring clarity to the world.
