At the end of the Southern Song Dynasty, the peace of the Central Plains was shattered by the golden armies and iron horses, and half of the country fell into the flames of war. Su Muyun, the son of Yue Fei's old tribe, carried half of a jade pendant as a token and inherited his father's last wish to embark on the road of serving the country and seeking friends. During the battle at the Black Wind Channel of the Yellow River, he used his exquisite swordsmanship to save the anti-gold herbal escort team of the Zhenyuan Escort Bureau. Since then, he has formed an indissoluble bond with Yanmen Pass.
When Yanmen is closed, he meets Yan Beifei, an anonymous anti-Jin warrior, and uncovers the past of his father and Yue Fei fighting against the Jin together. In the court, Qin Hui's gang members frequently make treacherous plans, loyal ministers and good generals are falsely accused and exiled, and the justice of the family and country is at stake. From the life-and-death fight at night in Hanjiang, to the bloody defense of the city in front of Yanmen Pass, to the desperate counterattack in Lin'an City, Su Muyun and Yan Beifei stood side by side with Zhenbei General Zhao Xiaotian, the old hero Han Shizhong and others. Using swords as pens and blood as ink, they wrote a righteous chapter of "resisting the Jin Dynasty, restoring the Song Dynasty, hoeing out traitors and defending the Tao" in the troubled chess game between the Song and Jin Dynasties.
The grievances and grievances of the world are intertwined with the righteousness of the family and the country, and the love of children is blended with the iron-blooded loyalty. This is not only a dispute about the righteousness of martial arts, but also a heroic song to defend the mountains and rivers of China. It reflects the bravery and loyalty of people with lofty ideals in troubled times, with their chivalrous bones and blood to their home and country.
