War is a meat grinder.
To decide the outcome of a domain conflict based on whether one can defend the border seems considerate for the lives of the common folk throughout the region.
Yet, it is precisely such a cruel mechanism that will cause this war machine to run at full power.
The border will become incomparably brutal.
Because neither side has a way out.
If the Luoyang Domain fails to break through the border within thirty years, it signifies defeat.
The defeated side must compensate the victor with half of the cultivation resources of their entire domain unconditionally; if unable to do so, the Upper Realms will intervene.
If the Chengshan Realm doesn't need to compensate, it may choose to counterattack. Once it breaches into the Luoyang Domain's border, it means that the Luoyang Domain will be swallowed by the Chengshan Realm.
