Fleeing in panic, the demon cultivators naturally thought the farther they got, the safer they would be, preferably in a place where the local powers weren't too strong.
That way, they could use the local cultivators to quickly recover from their injuries.
And Wanxian Province, over ten thousand miles away from Xuanfa State, seemed like a great destination.
It was sufficiently remote, and the majority of the local forces were Golden Core and Foundation Establishment; the only Nascent Soul family, the Li family, was situated on an island thousands of miles away.
By the time the Li family reacted, they and their companions would have long since vanished without a trace.
So, a group of demon cultivators who fled to Wanxian Province didn't continue to flee, but began to pillage and plunder, planning a quick looting spree before their departure.
