Generally speaking, a domain was boundless, encompassing countless cities.
A city was merely one corner of a domain.
Taking Great Xia as an example, a small city had tens of thousands of inhabitants, a large city a million, and even a metropolis only five million.
A domain, however, had a population of at least a trillion.
The difference between the two went far beyond that between clouds and mud.
"City is the old term. Some people still use it today. Eighteen hundred and thirty-two years ago, the Nether Realm redesignated its cities as domains!"
"May I ask, Senior, how many beings live in a single domain of the Nether Realm?"
"Fifty in a small domain, a hundred in a medium domain, and two hundred in a large domain!" Li Sanniu held nothing back.
"Five hundred thousand, a million, two million... Strange. With the Spirit Realm's enormous population, how could these numbers be lower than Great Xia's?" Xiao Chen asked in puzzlement.
"You misunderstand, Young Master. The unit I used wasn't ten thousand!" Li Sanniu shook his head.
"Not ten thousand?"
"Correct. I meant a hundred million!"
"A hundred million?" Xiao Chen's eyes widened in horror, leaving him speechless with shock.
A single city—a small domain—had a baseline population of five billion? And medium and large domains doubled that again?
Places like these had once been called cities?
No wonder the Nether Realm's rulers had later redesignated its cities as domains.
With such dense populations, calling them cities truly was inappropriate.
A single domain held five billion, or even tens of billions.
There were more than thirty-six thousand seven hundred small, medium, and large domains.
The entire Nether Realm had at least two hundred trillion inhabitants, fully ten times the population of the Azure Spirit Ancient Realm.
The sheer immensity of
