'Did you end up counting the plants?', Shin asked with a funny gaze.
He was indeed confused by that. Weren't humans the only one lived there?
That was something he didn't know but just assumed. Of course, humans were a highly intelligent species and were greedy too. They even tried to show tendencies of dominating others.
So based on that, it wouldn't be unusual to see slaves present in the kingdom and probably the total population was more precisely because of that. But for a kingdom, that was still quite less.
No wonder it was a kingdom with so little population despite having lost of riches.
Shin received all this info from the system soon enough and he understood everything in detail - about the slaves and their uses too.
There were 3 types of slaves present in the kingdom, in fact, in the whole world.
One - the ones that were bought and used for pleasure: mainly sexual pleasure and entertainment.
