A boy wakes up with omnitrix as a X-GENE

In the waves of steam and machinery, who could achieve extraordinary? In the fogs of history and darkness, who was whispering? I woke up from the realm of mysteries and opened my eyes to the world.

France, 1934. The scars of the Great War still shape the military minds of the Third Republic. Trapped in the past, its generals place their faith in fortifications and defensive warfare, while across the Rhine, a new German army rises, faster, deadlier, and ready to crush everything in its path.Into this world awakens Captain Étienne Moreau, a man who should not exist. He remembers another life, one where France falls in 1940, where German tanks storm through the Ardennes, bypassing the Maginot Line. One where his country surrenders in a matter of weeks.But here, now, he has a chance to stop it.As an officer in the 2nd Armored Division, he fights for reforms: pushing for mobile tank warfare, warning of Hitler’s growing ambitions, and challenging the high command’s obsession with World War I tactics. Yet, his ideas are dismissed as radical, madness from a young officer who “thinks he knows war.”Surrounded by political intrigue, military infighting, and rising fascism, Moreau must carefully navigate the system, winning allies among future leaders like Charles de Gaulle, while avoiding suspicion from the French High Command. His knowledge is a double-edged sword, if he is too aggressive, he risks being labeled a traitor. If he does nothing, he will live to see France burn.As war draws closer, Moreau faces a terrifying question: Can history be changed? Or is France doomed to fall, no matter what he does?Time is running out. The Blitzkrieg is coming. And he may be France’s last chance to fight back.
