If you think about it carefully, subdividing the other civilizations into subordinate ones does make some sense.
After all, in this world, only the Twin Tree Civilization has external enemies—the Youhan Tree.
Entities like the Mechanical Civilization·Magic Furnace don't face such formidable foes! The crises within their continental civilization mostly originate from internal human conflicts.
It's saddening that where there are people, war becomes the main theme.
Undoubtedly, crises are a good remedy for fostering unity among humanity.
And when crises aren't imminent, nations will attack each other, and the Human Race will engage in wars and internal strife in various forms.
The Twin Tree Realm has nothing to be proud of; the Great Xia Continent went through the same.
Since the birth of the Kunlun Divine Tree, this continent only has fragmented periods of peace.
