War had never been a small matter. Even in the cultivation world, where there were countless convenient conditions, there were still many places to prepare in the time of war.
In a war between mortals, there were countless conditions to mobilize troops. The first one was the transportation of materials. War relied on logistics and money. If you didn't have materials, how could you fight? therefore, logistics and supplies had always been a big problem in a war between mortals. In many wars, the losing side lost because their logistics and supplies couldn't keep up.
However, there was no such problem in the cultivation world, because there were spatial preparations in the cultivation world. Every cultivator could store what they needed in their own spatial equipment, so they didn't have to worry about logistics.
