In the chaotic times of the late Sui Dynasty, Emperor Yang visited Jiangdu in the south, and war broke out all over the world. Yu Wenhao, a young man from the Yuwen clan, was involved in an assassination plot and was forced to join the mysterious organization "Long Yuan Society", only to discover that his mother's death was connected to the secrets of the society. Under the guidance of Long Yuan's envoy Murong Zhi (the daughter of the former prince Yang Yong), he dealt with Yu Wenhuaji, Sima Dekan and other powerful officials, and personally experienced the Jiangdu mutiny.
In order to find the national jade seal, Yu Wenhao went to Chang'an and confronted Li Yuan's forces who had raised troops in Taiyuan. During this period, he got acquainted with the heroine Su Piluo from the Western Regions and the eminent Buddhist monk Huiming, and even started a fateful duel of "Chi Kiss and Ya Cane" with young Li Shimin. In the chess game composed of historical figures such as Yuan Tiangang, Du Fuwei, and Empress Xiao, Yu Wenhao gradually uncovered the century-old secrets of the Long Yuan Society - an organization composed of descendants of the previous royal family, who are looking for the "True Dragon Emperor" who can end the troubled times.
The work combines real historical events with martial arts fantasy. Based on historical facts such as the Jiangdu Mutiny and the Jinyang Rebellion, it interprets an epic legend surrounding the national jade seal and destiny. Yu Wenhao finally made a choice between personal grievances and the world, witnessing the historical torrent of the Sui and Tang dynasties.
