There were a lot of groups within the darkness silent divine.
Their goal was to completely blend with the darkness itself and get closer to the divine powers of the darkness divinities. The only way to achieve this goal was by completing the missions and getting enough kills in the darkness world.
This is applicable in all the darkness worlds.
Xue Ren's main goal was to kill someone and get his indentity. This way, he would blend even better as most people just aim to kill each other at every step. Because of that, it's far harder to notify each other about one's movements.
Even so, he was also checking up people's weapons.
Everyone was using short weapons such as knives, daggers or short swords. His main target were naturally those who had the knife qi from the divine alliance. This way, Xue Ren would at least find some clue to Eva who also should be somewhere here.
