The 28-year-old modern public relations director Zhang Qingshan is recognized as a "love saint" in his circle of friends. However, after an accidental car accident, his soul traveled back to the Huizong period of the Northern Song Dynasty and became a descendant of Bao Zheng - the down-and-out scholar Bao Bo. Starting with a broken bed, full of debts, and being pressed step by step by the descendants of the Pang family, he originally wanted to use the "love saint" method and the famous prostitute Li Shishi as a springboard to cling to Huizong and reverse his destiny, but he did not expect that this trip would break his guard.
He used modern thinking to establish a foothold in Luzhou, won the hearts of the people with the reputation of the Bao family, and counterattacked all the way to Bianliang. However, while dealing with Li Shishi, he was moved by her cold demeanor and melancholy in troubled times. When "use" becomes "protection", and when power meets sincerity, he not only has to fight against the conspiracy of the Pang family, Cai Jing and other powerful traitors, but also has to use his meager efforts to rewrite the fate of the Northern Song Dynasty under the shadow of the "Jingkang Incident".
A love that spans a thousand years, a legend that begins with calculation and ends with deep affection. Let's see how the contemporary love saint, amidst the crisis of the Song Dynasty and the crisis of his family and country, blazed a path to change his destiny for Master Li and the world.
