This is a rousing tale steeped in the smoke and flames of war. An unwitting act by the laborer Wu Dingniu leaves two Japanese tanks trapped with no way out. Ren Guangzheng, a company commander in a unit of the 29th Army, is preparing to wipe out the invading enemy when he receives the absurd order to help the Japanese push their tanks. The tank incident becomes the spark that ignites years of grudges between Ren Guangzheng, Xing Baili, and Wu Dingniu.
With their country fallen, Wu Dingniu and Ren Guangzheng both join the National Salvation Army founded by Xing Baili. The National Salvation Army is a weak force that no one expects to amount to anything. Wu Dingniu's bizarre schemes and Ren Guangzheng's fearless fighting lead the army step by step toward glorious victories. But those victories bring internal division and hostility. After failing to assassinate Wu Dingniu, Ren Guangzheng takes some men and defects, joining the Nationalist Army. Wu Dingniu and the National Salvation Army, meanwhile, are reorganized into the Eighth Route Army.
