Destroying a civilization on the same level was indeed extremely difficult, let alone a civilization with combat power as exceptional as the Pudolad Civilization.
Even so, it was ultimately wiped out by the Galactic Great Voyage Organization.
Worried that the Pudolad Civilization might still have some of its individual lives hidden among the stars, the Galactic Great Voyage Organization formed a special probe force led by the Silver Heart Civilization and kept it patrolling nonstop for thousands of years. With support from countless billions of probes, it could be said to have conducted a carpet search of the entire Houqi Galaxy.
The moment they found the slightest clue related to the Pudolad Civilization, the Great Voyage Organization would immediately dispatch a fleet to encircle and annihilate it.
Something like that had happened before.
About two thousand years ago, during a search, a Silver Heart Civilization Probe Team discovered a small fleet of roughly a hundred-plus ships in a void space rich in Dark Matter mines. They were developing and utilizing the Dark Matter mines under communications silence.
It was later discovered that this was a fugitive small fleet of the Pudolad Civilization. There were probably several million Pudolad people in the fleet, and they intended to quietly develop and recover out in the void.
In the end, of course, they were destroyed by the Silver Heart Civilization.
There were many similar cases as well, though the locations differed.
Some strongholds had been found on remote planets in certain Star Systems, while others were hidden underground on planets. The former were relatively easy to discover, but the latter were much more difficult. If it was just ordinary patrol scanning, as long as those underground facilities remained in a silent maintenance state, they basically could not be found. Only when they activated
