Chapter 866 - Finally the Boss monster appears

Sometime later,

You can already see that Alena and the others have already killed half of those Monsters who tried to attack them. Naturally, those other monsters did not stay ideal and they continuously approached them. None of those monsters have any kind of expression, even if their companion gets killed by their enemies. 

It is like they did not have any kind of emotion or anything like that. Currently, monsters present in that place just want to kill all the humans. You have to say that the situation was quite dangerous at first. Sam even needed to help them to kill some of those monsters. 

It is a good thing that Alena activated the barrier given by Sam. Only because of this is she able to maintain that barrier even after getting continuously attacked by those monsters. Also, after using their full power continuously, all of them become exhausted. This would be the first time they became that exhausted.
