Zhou Tian was already in such a situation, one could imagine that the monsters with average strength would definitely not want to provoke players no matter what.
Therefore, it doesn't matter that the things Zhou Tian has been doing haven't spread yet, even if those monsters were to learn of Zhou Tian's actions, they might feel amazement at his performance, but to expect them to act as Zhou Tian did was certainly out of the question for those players.
So, even if the NPCs themselves spread the news, it was expected that at the time no monster would have the courage to enter their sphere of influence. And based on that situation, it was without doubt that the NPCs' arrangements would have no effect whatsoever.
