The things Zhou Tian had done before were already placed out there, and those NPCs were quite wary of him. After all, those NPCs had been injured previously under Zhou Tian's hands, so when facing Zhou Tian's actions, those NPCs naturally wouldn't dare be careless.
As a result, as soon as Zhou Tian's large army moved, the NPCs quickly responded. They may not necessarily capture Zhou Tian, but when facing him as an opponent, those NPCs had made up their minds; they absolutely wouldn't let Zhou Tian break their castles easily again.

Knowing that Zhou Tian and the goblins, these two hostile forces, had actually formed an alliance, the higher-ups of the NPCs were frightened.
