Only the monsters truly understand the extent of the threat posed by the players. But once they have Zhou Tian's ability, that means they will no longer fear the players' threats. The existence of such an ability carries great significance for both players and monsters.
As long as Zhou Tian's ability is revealed, the players, bereft of their original advantage, are not really capable of countering those monsters with their strength. So, technically speaking, Zhou Tian can now be considered the nemesis of these players. Unless some special circumstances occur, wherever Zhou Tian is, it would be hard for the players to maintain their current dominance.
From the players' point of view, they probably wouldn't think too much about it. After all, they could simply drop this world like a game when they don't want to play. However, the monsters and NPCs consider a lot more after seeing Zhou Tian's ability.
