According to Xiao Xue's foreknowledge, the four worlds under attack are BDE-1325, AC-67, TEA-6, and NF-15. The Local Defense Army in these worlds is already prepared, and four Imperial main forces are ready to deploy, thanks to the Empire's space transmission and world transmission technologies. The advance warning of a few hours is sufficient for any force to prepare for defense, but to prevent accidents, we also mobilized part of the troops resisting invasion at XF-35-A to reinforce the defense lines of these four worlds.
