Zhang Yuan whispered, "So, the development of this civilization is slightly different from that of humans, but it is quite easy to understand. The abolition of slavery has always been determined by productive forces, not by moral transformation or the calls of a few knowledgeable people..."
"Economic foundation determines the superstructure; it is only overturned by the great trends of the times when it truly hinders progress. This should be a commonality among civilizations."
"As of now, those small countries that still retain slavery are basically not yet industrialized, and slaves still play a significant role. This planet is simply too vast, transportation is inconvenient, and it is something like the emperor being far away; other countries simply have no interest in dealing with these countries."
"Furthermore, with transportation being inconvenient and no satellites or major powers acting as global police to criticize human rights issues, it's simply a thankless task."
