The NPC faction would surely be reluctant to see their city fall into the hands of Zhou Tian and his group. However, even if those NPCs didn't want to see that situation, due to the fact that they couldn't spare any manpower to send them aid at that time, what difference would it make if they didn't want to witness such a situation? If they were incapable of saving that city, all they could do was to helplessly watch as Zhou Tian and his group ravaged their territory, finally letting the city fall into Zhou Tian's hands.
Having successfully occupied the city, Zhou Tian was not surprised. After all, the disparity in strength between the two sides was evident. Zhou Tian and his group taking the city was nothing more than normal. On the contrary, if, in the end, Zhou Tian and his group failed to secure the city, then that would be the abnormal situation.
After capturing the city and distributing their respective interests, this operation came to an end.
