It took the monsters two full days to move to the 20th floor, except the Demon Spiders. Jake had told Isa that she could have the 25th floor all by herself and her spider babies.
For any normal human, they would need more than a month to reach the 66th floor from the 1st floor. That's how big Jake's dungeon was now.
After the monsters gathered on the 20th floor, Jake gave them orders on where to stay.
First of all, the goblins. He told them to go straight to the 7th floor and settle there. The goblins Jake had earlier bought were also there.
After that, the orcs. They were quite high in monster hierarchy. Strictly speaking, they were better than even humans if not for their abysmally low birth rate.
If Jake could solve that, he would have a ferocious army at his disposal. Jake decided that they could stay on the 20th floor.
Likewise, the lizardmen and wolf packs went to he 19th floor. The kobolds as well as the gnolls went to the 18th floor.
