Legend of the Paladin
I feel a bit bad for the celestials. If they'd come a thousand years ago they would have been able to cause chaos due to the simple difficulty the cultivators have in sharing information. By the time who they were and what they were after was common knowledge, the damage would have been going on for a while. Thousand mile talismans or whatever they're called being the only means the ancient cultivators had to communicate at a distant with all their limitations and also being expensive consumables, is a big handicap. Today? They're all online. They knew within days and were organising a freaking event! The celestials must be shook~
