For now, even if Lin Yu broke through the Empire's second and third lines of defense, Radu had not ordered them to pursue.
After all, once the fleets stationed on those defensive lines left, if the Alliance disregarded casualties and directly broke through the first line of defense, they could charge straight into the Empire's mother universe without obstruction.
The fleets were one thing, but Radu did not dare allow strategic weapons like those of the Federation to get close enough.

That thing's range was simply too great, and it was almost impossible to defend against.
After all—
Ever since Toreya's death, the Empire no longer had any Sixth Tier powerhouse.
Therefore, once such a weapon got within range, it could even ignore the defensive line entirely, punch through it with a single strike, and destroy the Black Hole Cavity Particle Annihilation Device behind it.
