In the troubled times at the end of the Yuan Dynasty, Qinling boy Shen Lie and his adopted brother Liang Youqian were hunted down by Mulda, a hundred households in Mongolia, because of their family's martial arts skills, and were forced to join the Red Scarf Army uprising. From the fierce battle in Huaixi to the decisive battle in Dadu, the two brothers grew into anti-Yuan generals in the blood and fire. The novel uses twenty words and brand names to connect the feuds and dynasty changes in the world, and the realistic martial arts scenes testify to the book of war. It not only contains the martial arts philosophy of using Tai Chi sword skills to overcome strength with softness, but also the compassionate sentiment of "stopping war with force", showing a magnificent epic of young chivalry intertwined with the righteousness of family and country.
