In 1937, military graduate student Lin Yuanhunchuan became a German weapons division battalion commander on the Songhu front line. Wearing a German M35 steel helmet on his head, he commanded a tired and poorly equipped division, and faced crushing Japanese artillery fire. He knew very well that this "model" army was about to be tragically destroyed in history. But this time, he will rely on his passion and insights beyond the times to keep the first everlasting fire for the war of resistance. From the flesh-and-blood mill in Songhu, to the desperate beacon fire in Nanjing, and then to the decisive battle in Taierzhuang, he not only has to use his ingenuity to rewrite the local war situation, but also to walk a thorny road of building an army, educating people, and saving the country amidst the conflict between factions and ideals. This is not a battlefield for one person, it is a legend of an old army being reborn and looking for its true military soul.
