As the attacks outside continued, the defenders inside Star Dou Fortress fought desperately to resist, but the enemy's firepower pinned them down so hard they could barely raise their heads.
That dull crash of collapse seemed to announce something to every defender on the walls.
Then breaches began appearing in Star Dou Fortress's outer metal walls, and the Integration Movement forces poured through them. As the Integration Movement forces entered, the battlefront began pushing into Star Dou Fortress itself.
After this first breach appeared, the Black-Grade Mechas in the other directions also finished cutting through the metal walls one after another. This formally marked the collapse of Star Dou Fortress's outer defenses.
Once this happened, the mecha corps stationed inside the fortress were immediately mobilized at the sight and rushed to plug the breaches.
However, the instant dozens of mechas reached that breach, a streak of black light flashed past. The dozens of mechas that had come to reinforce it were instantly cleaved in half at the waist.
The mecha pilots in their cockpits had no time to react before the mechas they piloted were cut into two.
A Bao did not pause at all. Instead, he immediately moved forward to attack the interior of Star Dou Fortress. Behind him, many members of the Integration Movement kept pouring in, fighting the fortress's defenders in every passage.
In another direction, inside a passage in Star Dou Fortress, the defenders behind a hastily erected defensive line stared ahead in terror.
Even with mechas and Battle Armor Masters joining them from behind, they felt no sense of safety facing what stood before them.
A tremor came, and then a huge Golden Crocodile Emperor suddenly lunged around the corner.
At this sight, almost all the defenders frantically began attacking, firing Soul Guidance Rays ahead.
