Wei Zhao, a modern military fan, accidentally traveled back to Berlin in 1945 at the end of World War II and possessed a young German soldier named Klaus. Facing the Soviet army's steel torrent and the Third Reich's desperate struggle, his only thought was to survive. Relying on military knowledge and tactical literacy far beyond the times, he repeatedly performed miracles on desperate battlefields, and gradually became the core of the team's turnaround from an inconspicuous soldier. He is not a believer in the Nazis. In the mountains of corpses and seas of blood, he just wants to take a few trustworthy comrades and innocent civilians around him to survive until the end of the war and find a way home, or a way to survive.
