Chapter 69: Chapter 69- D-Rank Mission (Part 3)

The inside of the factory was very dark and humid as if it was the interior of some old dungeon.

The floor was made out of broken tiles and the walls were rusty to the point where they threatened to crumble down at any given moment.

There were even bats hung up on the wall and rats living in the corners of the corridor. All in all, it was a place worse than the sewage pipes.

Even Acht had to close his nose to stop the horrifying smell from invading his senses.

He then moved quickly until the end of the corridor while keeping his presence as hidden as possible since he knew there was a person inside with him.

When he reached the end of the corridor, he found a stairway that led deeper into the factory. Or to be more precise, the factory's basement.

After making sure no one was close by, he made his way down as carefully as possible.

The stairs were very long so it took him some time to reach the basement. That's when he heard something.
