They could clearly see all the people were restrained to the bed with no movement allowed at all.
Their limbs were all properly restrained so that they couldn't move at all.
However, even if they weren't that restrained, Luciel knew that most of them couldn't move at all.
He could see that most of the people were already unconscious, so even if they didn't have any restraints, they couldn't move at all.
"F*ck!" Nathan murmured, but it could be heard clearly because it was already loud in such a silent place with just the beeping sound of instruments around.

He had also seen much worse scenes than the one he was seeing now in the world he was in, in the past.
