The Edge of the Blade: From Platoon Leader to Marshal

After transmigrating into the role of a second lieutenant platoon leader on the border of the Republic of Nanyue, Lin Yuan faces a defensive line on the verge of collapse and a nation about to be swallowed by war.

The Beilin Empire has torn up the peace treaty, and its armored forces are bearing down on the Mo River. Lin Yuan has only one platoon, a few dozen soldiers, and a mind full of modern tactics. But no one knows that whenever he closes his eyes, the entire battlefield unfolds in his mind: troop strength, terrain, firepower, and time, all laid out as a "battlefield simulation table."

"A flood of steel can crush a defensive line, but it cannot crush the will of those protecting their homeland."

This is a war against invasion, and the story of a soldier who grows from a platoon leader amid the flames of war.
