In response to the Galactic Great Voyage Organization's questions, the Kroll Civilization explained it plainly: it was a "siege." If they wanted to defeat the Boundary Breakers in a galaxy and bring them under their control, the only way was to attack by force through the Star Gates.
They had also considered using Warp Speed Travel to cross the space between galaxies and launch a sneak attack, but that simply was not realistic. First, crossing between galaxies required the fleet structure to be converted into long-voyage mode. Second, the distances between the galaxies in this star region were far too great; without laying down star routes in advance, there was no way to make the crossing.
It could be said that without the Star Gate Network, the latter half of The Great Voyage Road would likewise have taken a very long time.
But reality had no ifs. The current situation was that the three great voyage organizations had to defeat the Type II Boundary Breakers stationed in these galaxies, and beat them into submission so they would not dare come cause trouble when the great voyage organizations entered the Great Void.
At first, the Galactic Great Voyage Organization had still wondered why they did not wipe out all the Type II Boundary Breakers, but later learned that there were simply far too many of them. Almost every galaxy near the Great Void that the Star Gate Network extended into had them.
They had been living and multiplying here for who knew how many hundreds of millions of years, and their numbers had already reached an uncountable extent. With the capabilities of a Level Six Civilization, completely eradicating them was simply unrealistic.
In fact, if not for the Type II Boundary Breakers' inability to leave dark matter, their territory would have
