More than a hundred thousand years ago, when the Evil Tide Civilization began annexing and conquering its first top-level civilization, it took over thirty thousand years from start to finish.
When conquering its second top-level civilization, that time was reduced to twenty thousand years.
For the third top-level civilization, the Evil Tide Civilization needed only twelve thousand years to conquer its opponent.
After that, the Evil Tide Civilization maintained its momentum of annexing roughly one top-level civilization every ten thousand years.
Some top-level civilizations even held out for only a few thousand years before being annexed.
Of course, a few civilizations endured longer.
But in the end, the Evil Tide Civilization still maintained its impressive pace of destroying one top-level civilization every ten thousand years on average.
There were two reasons for this. On the one hand, one of the Evil Tide Civilization's Supremes was exceptionally skilled at "calculation."
Most of the civilizations it chose to attack were World Civilizations whose Level-9 Beings had only just left the Star Realm, leaving their own civilizations conveniently hollowed out.
These World Civilizations were primarily those that had only recently entered the ranks of top-level civilizations.
For example, this time, the Evil Tide Civilization had calculated that a Level-9 Being seemed to have broken through in the direction of the Minghe Empire three hundred years ago.
Judging by the normal period a Level-9 Being could remain behind,
more than three hundred years had passed. That being should have long since been rejected and forced out by the Star Realm!
That was why the Evil Tide Civilization had set its Evil Tide Vortex upon this star region.
As for the war currently erupting between the Minghe Empire and the Light Dimension Country, it was an unexpected delight for the Evil Tide Civilization.
