Despite the Wolf and Weisbach families having declared war, it was not as if the Wolf Family could say, "I'm going to attack you," today and then show up at Mingxing City's doors tomorrow.
In the semi-feudal, semi-industrialized Divine Luo Empire, preparations for war were still relatively lengthy. First came the formal declaration of war, then under the wartime status, the concentrated military forces began to mobilize, mainly calling up the vast number of vassals and knights under one's command, especially those with Transcendent abilities.
Before the declaration of war, it was, of course, also customary to leak word in advance, allowing one's subordinates to make at least minimal war preparations, such as material and personnel movements.
