Since there was no one left inside the enemy base, it was clear that Du You couldn't afford to delay any longer. But not giving the enemy enough time wasn't an option either.
So while Du You continued to move forward without slowing down, whenever he passed by a base, he would carefully inspect it in great detail, and then proceed to destroy the base afterward.
These bases, when it came time to rebuild Harry Asteroid, wouldn't be kept anyway. Using such a method, Du You finally managed to stall for a few hours, giving the enemy ample time to fully assemble.
But the air defense circle wasn't so lucky. The space weapons couldn't reduce speed or change course; they could only move forward at a consistent speed. Xiaozi, with the Black Jade Griffin King and the Dark Dragon, simply waited in ambush, sparing any worries about the enemy not coming and saving energy effortlessly.
