Under the joint command of the two Emperors, the Imperial Army's front lines shrank in their entirety. After launching an ineffective Emperor's Breath, the Celestial System Fleet voluntarily retreated to the vicinity of the Mobra Star System. Thereafter, we began to systematically abandon a series of remote heavy space fortresses in the Milky Way. Even though some of these fortresses housed genuinely significant space arsenals, these movements were completed within less than a day. Before the Revenge Army could react, the Imperial Army had already consolidated all its main forces, preparing a stance for a final decisive battle, which clearly took the enemy by surprise.
We are indeed preparing for a decisive battle, but not here.
