Managing the livelihoods of tens of millions of people is no simple task.
Even with the assistance of the more than a thousand people brought by Liu Feiyun, and later the addition of disciples from the Li Yang Cave Heaven to help maintain order, it still took three days.
Leave professional matters to professionals.
Gu Jinlai did not interfere with these personnel arrangements.
Moreover...
Thanks to the Demon Kingdom's plans to keep these tens of millions of people in captivity for the long term, the living conditions of these 1,040,000 individuals were not as miserable as one might imagine.
It could not even be said that they were starving or living day to day.
Several Demon Emperors have devised two strict promotion systems.
One system, for compliant citizens.
Everyone willingly accepts the dominion of the demons, governing the tens of millions of humans.
