Hiring an Emperor Mage
For over half an hour, the demon trio's screams filled the city. While elves were usually kindhearted, that depended on the people they were dealing with.
For demons, especially the ones who had massacred their kin, they didn't have a shred of kindness or pity in their hearts. In fact, they were filled with so much anger and hate toward them that they enjoyed listening to their mournful screams.
Ashton looked around and saw all the elves had cold sneers on their faces. He then looked in the direction where he felt the person torturing them was with a look of appreciation on his face.
If this person had killed them too along with everyone, the elves would be grieving their losses now, and their morale would be at an all-time low.
But by publicly torturing them, the demon kings no less, he was indirectly reducing their pain while telling them the demons weren't as horrifying as they imagined them to be.
