"Everyone's still sleeping... Good."
Raven mumbled after seeing the others sleeping peacefully.
He just finished cleaning up the Giant Gorilla's blood...
'Good thing the gorilla didn't wake them up.'
Raven thought.
He already knew that the Giant Gorilla will come to where they are.
That's why he stayed up and waited for it instead of resting.
How did he know..?
Because the place that their group is temporarily staying in... Belongs to that Giant Gorilla, that's why there's no monster nearby.
Monsters tend to avoid places that belong to the stronger monster after all.
In the novel... Alec and the others decided to settle in the same place when they were on this floor.
And when the night came and they were all resting, the Giant Gorilla came back to his base and saw them.
Alec and the others got their guards lowered because of exhaustion at that time...
So they got ambushed!
