Not a burial? Direct cremation?
Isn't that a bit personal?
"Together with the remaining bodies of the Church of Divine Punishment, they will be cremated," Autruck continued as he saw Wu Heng's serious expression, "Not converting them will save you a lot of trouble. Once you've earned enough merit to become a captain in a few years, there will be plenty of opportunities."
Everyone could see Black Stone Town's attitude towards Necromancers.
If he were really allowed to convert a level 12 body, it would just make people suspect if something special was going on.
Moreover, Wu Heng had only been a professional for a short time, and he already had a level 3 merit. Once he was assigned to a less strict place as a captain in the future, he'd have plenty of opportunities to own skeletons.
There was no point in being pedantic about this.
There are some things that one person can't change much, it's more about adapting and accepting.
