Wang Yuanfu, a modern military fan, accidentally traveled to Shanghai in 1940 and transformed into a young businessman. Seeing the mountains and rivers shattered under the iron heel of the Japanese army, he sold his property and bought a T-34 to fight. This was a passionate expedition across time and space. The tracks of the T-34 crushed the darkness, and they used their youth and blood to write: The real hero is to let steel melt faith and let the years remember the traces of burning blood.
