The plot of the uprising time is connected with the original work: the allies finally won the war with firm will, and most of the territory of the Soviet Union was occupied by the empire, but the imperial emperor Lang Fang died, and the prince became the new emperor, making peace talks with the allies and stopping the fire.
The war of the Soviet Union is a war to restore the country and to fight against future technology companies (that is, pioneers of invention, appeasers, future tanks, shameless companies beyond time and space ~)
The allied campaign is to station troops in the empire, suppress the imperial rebellion, and crack down on imperial generals who are unwilling to negotiate.
Japan used fire to resist the looting of the Soviet Union and taught the Soviet Union to restore its original military strength (after the war, the prince said: Thanks to you, our military strength in the Pacific was restored to the pre-war level)
There is also a battle in Yuriko. The story tells how he escaped from the Shenluo Research Center of the Empire, was captured after the defeat of the Empire, and then escaped from prison and returned to the Empire to seek revenge from the Shenluo Research Center.
The general plot is like this, you will know it after watching the opening movie.
