Those NPCs were already fed up with the two present monsters, so they would certainly not allow a third one of similar strength to emerge. In such circumstances, when they discovered that Zhou Tian's shown power far exceeded their expectations, those NPCs naturally hoped to eliminate Zhou Tian ahead of time.
In such a context, although Zhou Tian had just got rid of the neighboring NPC forces, those NPCs couldn't mobilize many strong individuals to block Zhou Tian due to lack of preparation. However, after everything was settled, those NPCs could still assemble some manpower if they were to grit their teeth; that was not a problem.
The manpower sent by those NPCs, clearly, could not face the Sheepman tribe head-on. But if they wanted to avoid ordinary Sheepman and assassinate Zhou Tian, there might still be some hope for success.
