Two male vampires had perished, and only one male and one woman remained. The two of them sensed their situation wasn't any good, and they would most likely end like these two. Therefore, they opted to surrender.
"Please, don't kill u-" the male vampire muttered, but Arthur ignored him, and cut his body in half.
The others from his squad that were hidden behind the tree came out, seeing that the fight was already over, and they did nothing to help. Arthur's strength was more than enough to deal with those vampires.
"Now, you will tell me everything."
Arthur did not kill the remaining vampire instantly, but first tried his best to get more information from it, saying that he would let it live if she provided decent information.
Obviously, it was a lie, and he killed her right after getting the answers he needed. Only someone stupid would let the enemy live, especially being inside their kingdom.
