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.

“For a long time, we humans have been like the chosen race, without any natural enemies, and have long been at the top of the food chain. Unfortunately, I have to tell you...” “When there is only one bird in a forest, then the forest is basically fake, and the bird was put there by someone...” “No matter how a fish swims, it can never meet any of its kind, which only means that the fish is kept in a fish tank...” “Yes, we are the birds in the forest and the fish in the tank.” “Yes, the world we live in is virtual!”

Everyone rumored that Z country’s young master Jun was cold-blooded, decisive, and not close to the female gender, but he took in an illiterate little girl as the pearl in the palm of his hand.

However, the little girl brought her case to the table. An illusion, it was all an illusion. What not close to the female gender? Which animal was crushing her every night?

“Baby, let me love you.” The man undressed her with his lips. She retreated pitifully, “Don’t want, don’t want, you’re bad.”

“Women love bad guys.” After eating he turned around to wipe his lips. She kneaded her pitiful little waist, tears falling, “This one is not a woman, she’s just a little mermaid.”
