Zhao Xu, a graduate student in the Department of Modern History, traveled through time and became the sixth prince of the Northern Song Dynasty. It happened that Jianghu forces (Beggars Gang, Mingjiao, etc.) Intertwined with court factions and foreign forces to cause chaos, and the people suffered.
With historical memory and modern thinking, he uses his identity as a prince as a shield and national law as a blade to break through the intrigues and rivers and lakes: he uses the intelligence network of Chu Qinghan, the owner of Tingfeng Tower, to gain insight into the secrets, explores peace with Princess Agula of Liao Kingdom, stabilizes people's livelihood with the businesswoman Su Wanwan, uncovers an old case with Mu Wanqing, the princess of Dali, and resolves the crisis with the medical skills of Medicine King Gu Lingsu.
He suppressed evil factions, introduced new laws, stabilized borders, and allowed national laws to penetrate the fog of the world. He also worked side by side with several women with different stances to find a stable course for the Song Dynasty in the waves of history and martial arts.
