As soon as Ning arrived in front of a sprawling city somewhere in Brazil where the only sound was that of the dungeon monsters running wild through the empty city, he left Sorlus and the others and teleported again.
He arrived somewhere in the USA as that was the place with the most people for now. He could also go to Canada, Mexico, and other close locations with dungeons in it.
A spear appeared on his hand and he moved.
The monsters had yet to reach the group of human hunters that were waiting for them to come. He appeared in their midst with a massive spear domain around him as he cut many of the monsters at once.
Wolves, skeletons, Basilisk, rats, golems, goblins, orcs, and many other types of monsters all died within a few minutes.
There were a few still remaining, but Ning left. He had other places he needed to help. He appeared somewhere else and killed a bunch of the monsters again before leaving for another location.
