Holy City - Nointana.
About every two months, a person of deputy regiment leader's level or above will be designated to lead a small-scale expeditionary action.
Even though the scale is small, the marching distance far exceeds the safe range of the Holy City, venturing into the Old King's territory as planned in the land deed. The expeditionary army is prepared to encounter the Old King from the very beginning.
However, the purpose of the expedition is not to reclaim some insignificant land deeds of no practical significance from the demons.
(With the Holy City as the base, it's hard to ensure the security of territories a hundred kilometers away, and it's impossible to station troops there for a long time under the cover of the eternal night... As for the plan of the "Second Holy City," it has not been implemented yet.)
Nor is it about weakening the overall strength of those outside the city, even if ten demons are slain.
