Players are natural enemies to all monsters, not just Zhou Tian who recognized the hazard they posed. The reason it seemed like only Zhou Tian was dealing with those players was simply that other monsters had no means to handle them. As the only monster capable of threatening players, Zhou Tian naturally and unconsciously stepped into the limelight at that time.
Therefore, the existence of players is a disaster to any monster that hasn't experienced their abilities. It's safe to assume that upon receiving relevant information about them, nine out of ten monsters would immediately take measures. The reason why the two Emperor-level forces that Zhou Tian targeted remained calm is simply because Zhou Tian had blocked the approaching players from their direction. Without Zhou Tian, they would likely be extremely worried about the emergence of these archenemies.
