At the frontmost part of the place that seemed both like a prison and a cemetery were thirty-six hibernation cabins that were streamlined and larger. They looked much more advanced. Observing through the translucent holes on them, it could be seen that thirty-six hibernators were also crouching inside like babies.
But different from those who were found guilty of 'instigation, insurgency, and jeopardy to national security', the hibernators had complicated, shining nails smashed all the way down from the back of their head to their spine every few centimeters. The tops of the nails were connected to each other with solid and complicated mechanical structures. They also spread to their limbs and extended to their fingertips, like some sort of weird external skeleton.
Li Yao thought for a moment and realized that the nails were probably bashed into the gaps on their spines in order to control their spine, their central nerves, and all their limbs and organs.
