Since the advent of an era of national cultivation, order in the cultivation world no longer depended completely on strength, where the strong were revered and held power. In this era, realm didn't mean anything. Strong cultivators who acted immorally or against the law would also be severely punished.
Peace.
This was what all cultivators on Earth worked toward, but there were also those who liked to act recklessly and break the law. The cultivation police was thus a necessary existence.
Apart from specially deploying civil police, the cultivation police had a large cultivator patrol team under their banner — the Immortal Arts Mobile Squadron.
