After Allen became a Domain God, he stayed low-key until he replenished the Divine Energy that Little Sun had used.
After gaining a domain in the Nine-Dragon World and making all its people his follower, it is not hard for Allen to gather Divine energy for Little Sun.
Although they had killed many people, those numbers are but a small fraction of the total population.
If the ones in the army of the nine emperors ranged from one to ten million, the total population would be about ten to one hundred times that.
Allen would only be able to kill all the people of the Nine-Dragon world if and only if the Nine-Dragone Emperors could make everyone their soldiers. But that is better said than done.
If they are going to do that, they will need an endless amount of resources, which they did not have. The Dragon Force alone that they use is limited, how come they would be able to have endless resources?
