Starting from the Line-Filling Soldiers, the Bloody Battle Begins to the End

[No system + iron blood + real battlefield + single female protagonist] A modern soul travels to the front line of a world war and becomes an ordinary line-filling infantryman. In his ears, he hears the scream of artillery shells, the roar of machine guns and the wails of his comrades. Steel and blood rolled forward. The pure instinct to live was an expensive luxury in the meat grinder. In order to continue breathing in the next second, he had to rack his brains, even if the glimmer of humanity was getting darker and darker. Penetration assault, armored lightning, air and ground integration. . . . In order to survive, to win, in the end, he became the most dazzling part of this cruel war machine, running all the way on the journey to hell.
