Fortunately, the Level Six Civilizations of the Milky Way Galaxy were considered peaceful now. Otherwise, given Silver Heart Civilization's current state, it might have been wiped out directly.

It was simply that it had too few warships now.
If it did not have its Characteristic Technology creations to back it up, some blind Level Six Civilizations might really come looking for trouble.
Because of The Great Voyage, any Level Six Civilization that understood its difficulty would drastically reduce its number of warships before setting out, thereby increasing its chances of survival while crossing between galaxies. After all, once they left the Milky Way Galaxy, it would be difficult to replenish supplies and fuel.
The combat strength of Level Six Civilizations preparing to depart was actually far, far weaker than when they had remained in the Milky Way Galaxy.
Therefore, if a Level Six Civilization wanted to undertake The Great Voyage, it had to ensure that the entire Milky Way Galaxy was safe and that it had no opponents. Otherwise, it would absolutely die before even setting out.
If there were still other Level Six Civilizations in the Milky Way Galaxy standing in their way, they would not even need to wait until now. They could be attacked while mass-producing transport ships or extracting resources on a massive scale.
Take Silver Heart Civilization, for example. It had also reduced its warship count to forty million. From the looks of it, if Star River were still around, it might not even have kept that many.
And if there were still an enemy, now would be the best opportunity for a surprise attack.
However, if that civilization possessed Characteristic Technology,
