In this place of perpetual darkness, the guards are like gods. They find every excuse to punish the children, just to make them live in fear, numb, and eventually become puppets at their mercy.
Who invented this "black prison" punishment is already unknown.
But there is one thing for sure, it is the most terrifying punishment for the children, far scarier than being kicked and beaten.
The black prison is a completely dark space, with soundproofing cotton on all four walls, isolating outside noises and preventing those inside from committing suicide by banging against the walls.
The interior is incredibly narrow, with walls so close that one cannot lie down. The ceiling is low, making it hard to stand straight, forcing one into a semi-squat position.
