Leon waited for several hours, but nothing happened. In case he received some unexpected visitors, Leon created a hole in the ceiling of the cave and hid it with the earth. Still, it wasn't a good idea to use that place to hide. If a mutant devourer appears at the same as the grizzly giants, his temporary hideout won't help him in any way.
"It looks like the grizzly giants don't intend to come... they probably already know about the usual time the mutant devourers appear, so I think I am safe for the time being."
Leon wondered if it wouldn't solve the problem, just kill all the devourers of the other world. However, in the end, he decided not to do that. First of all, if that were an excellent way to solve the problem, Ilyana would have told him that. The grizzly giants would notice that someone interfered with them if the monsters just suddenly disappear, so that wasn't a good idea.
