Originally, the difficulty of this "Great Graveyard" maze wasn't so outrageous.
The normal puzzle-solving procedure was for the Hunters to first deal with the Skeleton Monster in the maze, either by pushing them horizontally or using the San Value or other methods, until they found clues like an adventurer's notes in the monster pile.
Then they would trigger the hidden plot.
This is a long and meticulous exploration process.
With the clues, even if they encountered the "Keeper of Secrets", they wouldn't necessarily die.
But now, someone directly triggered the hidden plot, leading everyone to face a deadly situation as soon as they entered.
Fortunately, Leonard Churchill found a bit of a clue as soon as he entered due to his San Value, which was rather lucky.
But the threat of death was still there.
...
The magical thing about the maze was, it was a "maze".
If you haven't been through it, you wouldn't know where the paths lead.
