I Became a Tycoon During World War I: Saving France from the Start

A pure time-travel story without any system cheats—just intelligence and knowledge driving the narrative. If that’s not your cup of tea, feel free to skip!
The protagonist finds himself transported to the French Republic, born into a family that owns a long-standing agricultural tractor business. As the heir of this quasi-wealthy lineage, he’s about to become the third generation of success.
The catch? Their estate is near Paris, and the Germans will soon advance to this region. To secure his family’s future, he must save France itself.
Gallieni: “Good heavens, the enemy has actually exposed their flank to us!”
Joffre: “This can’t be true. Could it be a trap?”
Protagonist: “The plan is ready. Are you going to take action, or do I have to spoon-feed it to you?”
…
German Army: “This is supposed to be a tractor factory? What on earth are these steel monsters that seem impervious to bullets?”
