Both kingdoms began their preparations, but it would still take a few days for the Undead Army to get there. These few days were a critical time for the Blue Sand Kingdom to prepare on a large scale.
It was just that the Border Commander of the Blue Sand Kingdom was in a towering rage because his plans had been leaked unexpectedly.
Not knowing who was responsible, he could only assume there was a spy among them. So, while they continued their preparations, they also began an internal investigation. However, such investigations were merely a minor concern.
Meanwhile, the New Moon Kingdom had also begun to mobilize their troops on a large scale, even more so than them.
With no other option, the Blue Sand Kingdom had to see it through to the end, mobilizing not just the hired Undead but also their own forces. The scale of the mobilization seemed to be developing in a direction no one had anticipated.
