A modern soul who is familiar with Jin Yong's fourteen novels and is well versed in the logic of "Houheixue" accidentally travels to the world of struggle for hegemony constructed from Jin Yong's fourteen novels and possesses Wei Xiaobao, a young man in the Yangzhou Lichunyuan. The protagonist of Echigo (whose core is a modern soul) retains modern thinking and a precise understanding of Jin Yong's fourteen novels. He also possesses Song Qingshu's ultimate insight into people's hearts, his ability to turn danger into safety, and his precise means of capturing beautiful women. He knew very well that Wei Xiaobao's business slickness was not enough to gain a foothold in this world where princes competed for hegemony and martial arts were turbulent, so he used Wei Xiaobao's identity as a disguise to maximize the integration of modern wisdom and Song Qingshu's resourcefulness. He worked step by step, wandering between the courts of various countries and the forces of the rivers and lakes: in the northern borderland, he dealt with the forces of Kangxi of the Qing Dynasty, Wu Sangui, and Ali Buge of the Mongolia, taking advantage of the situation to climb up but always taking the initiative; in the hinterland of the Central Plains, shuttled on the edge of the battlefields of Jin, Liao, and Mongolia, relying on his foresight of the plot of the Golden Book to steal the "Nine Yang Manual" and "The Eighteen Palms of the Dragon" and other peerless martial arts; in the water town of Jiangnan, he went deep into the Song Dynasty court and the Honglou martial arts family, established bonds with Daiyu, Baochai and other Honglou beauties with unique skills, and used their martial arts power to expand his network; in the rivers and lakes, he contacted Mingjiao, Wudang, Shaolin and other sects, trying to integrate the martial arts power of the Han people, and find a place for himself and his confidante in troubled times. A large network of people in the rivers and lakes secretly plotted the chess game in the disputes among the countries.
