Most demons' thoughts are straightforward and simple. Baili An did not engage in discussions about the future world trends and philosophies like Su and Yin. He didn't waste much effort on emotional rhetoric to try to move the hearts of these demons.
He only had one simple statement: "I want to be your master."
Since he had other plans for this world, it was naturally impossible to just look out for himself alone. Baili An was not a sage of perfect benevolence. His heart had desires, so he naturally wouldn't uphold the conduct of a gentleman who claims to have no desires.
He offered no further explanation, and to these over a thousand demons, spending a huge sum to buy them and then becoming their master was not an excessive request.
After all, for humans chasing after profit, who would foolishly play the role of a naive philanthropist and engage in buying demons to set them free?
