Ling Pojun, the God of War in the North, held the iron-blooded military order in his hand, and tore the paper apart. The whole army knelt down, and the battlefield was stained with blood. He was ordered to defend Duanlong Pass, but he was betrayed by the court, his food and grass were cut off, and reinforcements failed to arrive. In the critical situation, Qi Jinyan, the son of the rebel general, led the Burning Flame Army to fight back, with his blade pointed directly at his old master. The former enemy is now a lonely sword. Ling Pojun didn't believe in the oath, and Qi Jinyan didn't believe in loyalty. But when millions of enemy troops pressed into the area, the two of them stood side by side on the ruins of a broken wall. A broken knife and two blazing flames tore apart not military orders, but the curtain of this decadent dynasty.
