In the third year of Xuanhe, Zhou Nian'an, a young man from Bianjing, learned that he was the illegitimate son of Song Huizong Zhao Ji after his mother Li Shishi died of illness. A phoenix jade pendant and a last-minute letter pushed him into the whirlpool of the fate of his family and country. Faced with the pursuit of Jin Guoxizuo, the strife of the powerful traitors in the court, and the complicated and unspeakable emotions of his father Zhao Ji, he gave up on recognizing his ancestors and returned to the clan, and chose to run for the country that was about to collapse in the name of "Zhou Nian'an".
He entered the palace as a spy and turned the tide in King Qin's clerk's office; during the siege of Bianjing, he bathed in blood on a snowy night to deliver the secret message of national salvation; after the city was defeated, he carried his genealogy and rode south alone, joining Han Shizhong's command, and "died" in the battle of Caishiji to express his ambition. After that, he changed his name to "Mr. Qin", hid in the spy shadows of Sichuan and Shaanxi, contacted Jianghu rebels, and became a sharp blade in the dark night that the Jin people were frightened by. However, when he rescued his father and brother from the snowy plains of Five Kingdoms City, he faced the suspicion and compromise of the Southern Song Dynasty court. In the end, in order not to become a stumbling block for peace talks, he drank the imperial poisonous wine with a smile and broke the Fengbo Pavilion.
Although he has not entered official history, his spirit has turned into wildfire and has been passed down from generation to generation in classics, music and folk memories, becoming the immortal "soul of the Song Dynasty".
