An ancient royal tomb reappeared, unveiling the long history of the Dayin Dynasty——
In the forty-eighth year of the Apocalypse, the government and the public were turbulent, and a political struggle forced Gong Yijing, who was tracing the real murderer of his family, to become the Shaoqing of Dali Temple. Huixuan Emperor Xiao Songkang was afraid of Xiao Ce, the prince of Beiqi who held military power, so he summoned him to Beijing as a hostage. Xiao Ce followed the trend and came to the capital Yanjing to trace the truth leaked by military planes seven years ago.
Thousands of clues are intertwined with each other, and a mutiny that has been planned for decades gradually comes to light. Gong Yijing and Xiao Ce fall in love with each other in the flames of war and conspiracy, but they are involved in the palace coup planned by the prince Xiao Zhen.
