Let's sort out the information for a bit.
In the end, the things I know are--
- The fiend drug was dumped to the sewage without proper processing.
- There's a possibility that it has been spread to the creatures living underground through the slimes.
- The Fiend Drug was mistaken with [Fighting Spirit Medicine].
This medicine has some similarity with the fiend drug, so it might be sold illegally in the downtown.
- People of the slum might have taken the fiend drug.
- The fiend drug isn't present in the Royal Capital.
Is that all?
No, there's one more.
- The monster disturbance might have nothing to do with the fiend drug.
Just when I thought I had seized the cause of the monster disturbance, the mystery got deeper instead.
I wonder if the case would be quickly settled were a great detective conveniently appear.
The phantom thief exists after all, wish the great detective too.
