Cultivators are fine, giving Spirit Stones in exchange for food is natural, and it can even allow the Yang Family, who hold a large amount of Spirit Fields, to earn a little.
But the Demon Clan in Zone 9... not only are they numerous, but they also have a good appetite!
Many demons are not accustomed to the life here, nor have they been properly educated. Quite a portion of them need the support of the Danai Dynasty to sustain themselves.
This point requires the Yang Family to allocate Spirit Stones for supplies, not because the Yang Family is virtuous, but because unfed demons... are a potential threat.
The main reason demons emerged from the Demon Realm is that... the Demon Realm cannot feed them.
