The only sound that filled your ears was the sound of footsteps, wacking, drilling, construction, etc.
And, occasionally, the underground shaking violently for some reason, which caused dust from the camp to only pollute the air more, causing more of the workers to get sicker..
You had already been here for a few hours and despised it. You had already lost the game of Rock, Paper, Scissors and you were unable to keep three or more stars. You didn't need this.
While eating your food, that was severely scarce and overpriced, meaning every worker there wouldn't have enough Perica to escape and finally make it back above, you suddenly heard a man complaining about the food price to one of the owners of the labor camps.
The man, Kaiji Ito, was definitely pissed off.
"You cruel bastard!!"
It was loud and annoying, but it wasn't too different from everything else in this place..
He knew the food and medicine was overpriced to ensure the people stay in the camp until they croak, and the oxygen was poor on purpose to ensure the people would spend most of their Perica on it and be unable to leave.
Kaiji continued to yell at one of the owners about the unfair price until they slapped him to the ground in front of everyone else who was eating.
