Bang!
Zhao Sheng and his three companions were walking in the corridor when a muffled thud suddenly came from the door of a cell nearby, causing the walls to faintly tremble.
Bang bang bang!
Following that, the huge sound of something slamming against the walls of the cell continued, as if a colossal creature was imprisoned inside.
At this moment, the prison seemed to be stimulated, as various strange noises began to emerge from several cells—thumping against walls, scratching sounds, ghastly howls, and chanting were all present.
Zhao Sheng wasn't surprised; the inmates held in the Sixteen-layered Prison were all difficult to deal with, and it appeared that some prisoners had turned into zombies after death.
The Black Armor Prison Guards were already accustomed to this, showing no emotion on their faces.
The four approached cell number thirteen, where the guard opened the cell door for Zhao Sheng and another person, but they did not enter, instead standing guard outside.
