Chapter 490 - Starenge person

All this time, Sam was just observing that person without doing anything. Well naturally he will only take action against that person when he will try to use the teleportation arrey or something like that so other than that he did not do anything and just silently watches that person to wait for weaker Monsters that are using the dark spiritual energy. 

But you can say that the same was really curious to find about that person who was using the spiritual Monster who uses the dark spiritual energy to recover from his injuries and also his health. He was sure that person wasn't an Abyss human. So that really makes me very confused about the identity of that person.
