He can admit that on the surface, the rank 6 divine beings don't look like they owe the sect any money. But when the life-leech is accounted for, then he believes that it becomes uncertain if the divine beings only owe the sect money and are not slaves to the sect.
After all, divine beings can't refuse to pay the life-leech. So it is certain that they owe the sect money. What isn't certain is whether the life-leeches turn divine beings into slaves for raising more lifespan for the sect.
To him, divine beings look like slaves because they have no choice but to pay the lifespan through the life-leech. But he also knows that divine beings have the option to give up their Divine Position in order to stop being drained of lifespan every ten years.
The thought made him laugh and say, "Ok, ok. Maybe they are not slaves. But they have to be called livestock at the very least."
