Part One [Forging Souls in Fire]: At the end of the Anti-Japanese War, Gu Tieshan, the master of Xingyiquan, and Shen Lanjun, the descendant of Baguazhang and an underground party member, pretended to be a couple in Linjiangtun, Northeast China, and established a blacksmith shop as a transportation station. Betrayed by the traitor "Black Fox", Shen Lanjun sacrificed her life to protect her husband and two sons. Gu Tieshan and his special force "Dragon Scale Thorn" snatched back the body of his beloved wife and fled across the river. His eldest son Gu Huaiyuan and his youngest son Gu Niansheng were separated while fleeing.
Central part [A Thousand Miles of Lonely Journey]: Gu Tieshan turned grief into strength and devoted himself to the torrent of revolution. From the liberation battlefield to the Korean battlefield, he chased the murderer for thousands of miles, and finally killed the "Black Fox" in a foreign country. At the same time, Gu Niansheng was taken in by the Liyuan Opera Troupe and grew up to be a martial arts student, but suffered many hardships in the turbulent times; Gu Huaiyuan inherited his parents' legacy and became a soldier, and spent half his life traveling across the country to find his younger brother.
Part 2 [The Return is Like a Rainbow]: In the early 1970s, Gu Huaiyuan, who had become ill due to overwork and was dying, finally found his younger brother Gu Niansheng, who had been separated for nearly twenty years, in a hospital ward in the north. The token "Dragon Scale Thorn" is reunited on the wrists of brothers. All the smoke of war, love and hatred in the past are at peace at this moment, but the character remains forever.
Intention: It is about a man crawling out of the grave to take revenge, a brother who spends half his life on the journey to find his relatives, and a family's undying character in the torrent of the times.
