In the last years of Yongle, a mysterious fire broke out in Nanjing City, burning down half of the imperial city and even burning the supplementary volume of the Yongle Grand Ceremony, which was about to be transported to the north. Gao Shuo, a member of the Jinyi Guard Qianhu, was ordered to investigate the case and unexpectedly discovered that there was a token belonging to the former Jianwen minister left in the fire scene. At the same time, frequent movements occurred in the old residence of Prince Yan in Peiping, and the White Lotus Sect quietly emerged in the south of the Yangtze River.

In the imperial power game between Zhu Di, Zhu Gaochi and Zhu Gaoxu, he must uncover the truth that has been hidden for ten years and prevent a shocking conspiracy that can overturn the Ming Dynasty.
