"Loyal Souls in the Fire" is an iron-blooded epic that spans the years of war. The soul of college student Fang Ping traveled back in time to 1937, starting from the Marco Polo Bridge, going through the defeat of Nanjing and the bloody battle at Taierzhuang, and finally chose to go north to join the revolutionary torrent. On the battlefield behind enemy lines, he integrated into the melting pot of the army and the people, attacked and attacked in the Hundred Regiment War, protected the people during the counter-mopping up, and transformed from a survivor into a warrior with firm faith. The cheers for the victory of the Anti-Japanese War have not stopped, and the clarion call for the Liberation War has begun again. He fought fiercely in Liaoshen, peacefully liberated Peiping, and witnessed the birth of New China. Before the war had cooled down, but the smoke of gunfire was rising again, Fang Ping and his comrades crossed the Yalu River and fought against the torrent of steel with their flesh and blood on the extremely cold ice field of Changjin Lake, creating an immortal monument. The war is over and the heroes return, but the systematic whispers and the mysterious "Night Watch" legacy herald the coming of a "big wind" sweeping across the country... This is not only a person's growth history, but also a majestic hymn to the majestic power of the people's war.
