If you think that way, you are gravely mistaken.
Although the Evil Buddha Clan can be considered an advanced civilization, in front of the Eight-Armed Snake Demon Civilization, they are merely slightly larger ants. As far as Song Chi knew, the Dominators in the Eight-Armed Snake Demon Civilization were never less than three digits, capable of annihilating the Evil Buddha Continent with a mere flick of the wrist.
Moreover, the Evil Buddha Continent's size, although impressive, pales in comparison to the Robber Star Civilization, which commands a territory of 800,000 light-years.
And why is the Eight-Armed Snake Demon Civilization so formidable?
That naturally stems from their individual combat power and the formidable Heavenly Serpent Warships under their command.
