Both Nan Luo and Feng Ao Kuai's face changed. Right, Zhang Xu Kingdom had been busy with their problem at the north border that they couldn't care that much about Han Zhong City. But this city was right in the middle of the three kingdoms (Fei Yang, Zhang Xu, and Wei Da).
It would be impossible for them not to care who owned this city.
There was once an attack from Zhang Xu Kingdom to Wei Da Kingdom in order to get Han Zhong City but failed. Wei Da Kingdom also knew very well the importance of Han Zhong City.
So far, there was no significant attack that reached Han Zhong City because General Feng and other commanders were raking achievements by clearing the area and built some smaller villages and cities. But it didn't mean that it would always be the same.
If the city was attacked, Nan Si Qiao would be the prime target.
Why?
Because she was the wife of General Feng.
