"Creak—Ten minutes for exercise, everyone out to the door," a commanding voice bellowed, echoing through the prison, stifling any thoughts of rebellion. Luo Zheng was startled and quickly halted his practice to get to the door. Suddenly, the horizontal iron bar at the entrance retracted into the wall, revealing an exit large enough for a person to pass through. Luo Zheng saw many inmates from the opposite cells stepping out, standing at their own doorways, scanning their surroundings indifferently, without straying.
After some thought, Luo Zheng decided to step out and observe. Cells were arranged in a swastika pattern, surrounded entirely by prisoner holdings. The courtyard featured two staircases, leading downstairs. In the middle of the courtyard was a void, and Luo Zheng glanced up to see a dense array of steel bars above, blocking any view of the sun and stars. The prison was a completely enclosed space.
