The distance between Yi City to the north border of Wei Da Kingdom and Fan Yi Kingdom was actually not that far. But the problem was the terrain that was filled with mountain's range and also forests.
There were not many people living here and it could be said that the north border was somewhat secluded.
For General Kai to be able to survive here without much reinforcement against Fan Yi Kingdom had shown that he had some capabilities. After all, Fan Yi Kingdom was not an easy opponent to deal with.
They took the route that was somewhat fast, but it still need them to climb the hills.
It would definitely be tiring.
"How long do you think it'll take for us to reach the border?" Nan Luo asked quietly.
Nan Hua passed a look at Nan Luo and then glanced at the West. "If we're using the plains at the areas that now belong to Zhang Xu Kingdom, we'll be able to reach the north border faster."
