In the Damaoling Miao Village deep in Mopan Mountain in western Hunan, young Li Musen and immigrant daughter Mo Wushuang have been dependent on each other since childhood. The navy blue cloth belt is a token of their first love. On the day of the drive, Chu Tianming, a descendant of the Chu family of the squire, humiliated Mo Wushuang, causing him to hang himself with hatred. Li Musen's father, Li Zhongfeng, was sunk to death by the government in order to seek justice. Li Musen, who was burdened with a blood feud, fled from the mountains to study martial arts in Guizhou's martial arts hall. Later, he experienced warlord melees and occupied mountains as bandits. Finally, he led his troops to join the anti-Japanese war and went to fight in Korea. He used his life's tenacity to complete the transformation from "revenge for personal gain" to "protecting the country." Tibetan blue cloth has always been his spiritual sustenance, connecting his longing for his lover, concern for his homeland, and protection of the people.
