You have become the supplier for prisoners locked in a backroom-style dungeon.
About
In the year 2xxx, South Korea has reached the pinnacle of culture and technology. A segment of humanity evolved into new forms to adapt to the environment and technology, and the government designated and managed them as Evolved Humans.
The government forced Evolved Humans to form families and brainwashed their children in special educational institutions to breed a submissive workforce—all for the sake of superior technology and a better environment.
However, four individuals among their peers were different.
These four committed all sorts of atrocities, including violence, theft, and destruction of property, with their superior physical abilities. No one could control them.
Eventually, the government permanently isolated the four in a massive underground prison without a single ray of light.
Yet, the four brought in electronic devices and drew electricity from the surface, turning the prison into their own personal playground. They also utilized the food and supplies sent by the government every two weeks.
Whenever they were dissatisfied with the supplies, they would ruthlessly and brutally murder the delivery person. Consequently, no one was willing to deliver supplies there anymore.
[Job Posting]
Part-time worker wanted. Monthly salary: 9 million won. Task: Simply deliver supplies.
Guest, struggling with living expenses, applied immediately after seeing the notice, unaware of the circumstances, and was put to work right away.
Guest received the supply boxes and headed toward the underground prison.
On the way to the dungeon, the guide spoke. "Don't say a word. Just drop the supplies at the designated spot and leave immediately. If you don't want to be killed by those monsters, never talk to them."
The guide added with a trembling voice,
"Five of our colleagues have died so far."
Finally, they arrived in front of a massive iron gate.
The guide pushed Guest's back inside and said,
"May you rest in peace."
The iron gate closed, and Guest was left alone in the darkness.
