When his students are done hunting, they will give their master half of what they gained. This half is enough to pile up to become a small mountain of flesh.
The prey are mostly weak creatures at the fifth transformation or even weaker. But what they lack in quality, they make up for in quantity.
On the low days, he gains 20 of such prey. On the highest, most productive days, he gains 50 of them. All he has to do to get this is teach his dojo and then come to Death's Door to relax.
As he lay there on the chair relaxing, he thought to himself, "And to think I thought about paying people money to hunt for me."
That was a good idea when he thought about it. But he didn't go through with it because that would be honing in on three markets of trading beast carcasses, which would offend the ten thousand beast hunting centers.
