The undead are Kant's most immediate threat.
At the very least, they had occupied the stone pass and displayed 10 royal knights, which was enough to intimidate the evil-minded noble. If they wanted to launch a threat of force, they had to at least get rid of these grand knights!
Well, if a well-trained knight is the foundation and backbone of an army...
Then the grand knight, the world's high-end combat power, is the measure of the real combat power of this army benchmark!
An army without an overseeing knight is nothing more than a garbage cannon fodder army made up of peasant and bandits. It has no effect on the real battlefield, only playing a small role in filling in the numbers, strengthening the momentum, and being the scapegoat in front, it was simply impossible to occupy them.
