The night proceeded as usual, with the vampire spawns continuing to abduct the citizens of Hannes City. The only difference was that the people from Count Hannes' side didn't try as hard as they did before to fight them back.
Because they needed most of the vampire spawns, or at least the one abducting Adam, to make it back to their hideout.
However, only the upper echelons of the city were aware of this plan. And that is why, there were still many city guards who died while fighting the undead that night.
If the Count wanted, he could have told everyone about the plan and drastically reduced the casualties. However, this could alert the Vampire Magus, and the Count couldn't risk it. He had to look at the greater picture.
That is why even though it hurt the Count to see his men die, he had to go through with it!
