Chapter 260: GoE 260 Huo District destroyed 

GoE 260 

... 

"Your Majesty, General Martinez has succeeded in destroying the Hou District. The latest reports are they have detonated an atomic bomb on an island," said Major to Emperor Paddu. 

"Good. Keep track of their movements. Don't let even the slightest report go unnoticed, understand?" said Emperor Paddu before they reached the capital of the Andromeda Galactic Empire. 

Not much changed after that, as transmissions between General Martinez and the Emperor's secretariat were interrupted when they entered the Andromeda Galactic Empire's Capital region. A big city is full of extraordinary protectors they have to penetrate with great difficulty.
