After leaving Mistila City and mounting a fast horse, it was not a long journey from the Female Warrior Tribe's territory to their northeastern border.
Once he arrived, Zhou Xu could have taken a train straight to Black Moon City, but he clearly had no intention of doing so at this time.
Ever since the railway opened, construction efficiency in the Northeast Region had risen dramatically. Previously, when sending troops to support the Smith Kingdom, they had gone straight to the border at top speed for the sake of efficiency, where they joined up with the Female Warrior Tribe's forces. As a result, he had barely inspected the construction situation in the Northeast.
Now that he had come all the way here, he naturally had to take a closer look.
At this point, as the highest-priority construction project in the Northeast Region, every facility in the entire border fortress, from the outside to the inside, had been completed.
At the same time, considering that this border might be invaded by a large green-skin army, they had specifically ordered the engineering teams to raise and thicken the defensive walls here.
The defensive walls here had now reached a height of fifteen meters.
At that height, even if ogres charged beneath the defensive walls, they would no longer be able to climb easily to the top.
