Cultivation Police

Cultivation originates from the east. However, it has since spread far from its cradle. In the modern world, immigration has allowed people to settle in various countries. Who is to say that cultivators can immigrate as well? Cultivators have since become citizens of France, Britain, US, Russia, Japan, Australia, etc.
Modern cultivation is still an exclusive community, however, even such communities must still be regulated by rules or the world would fall into chaos. That is why we have... Cultivation Police.
