Inside, numerous creatures and slaves were imprisoned.
There were Elves, Dwarven Elves, Dwarves, Gray Dwarves, Ogres, Trolls, Minotaur People, Dragonkin, and more than ten different types of creatures.
The deeper they went, the more slaves there were.
A portion of Serra's subordinates had already released all the intelligent beings imprisoned.
The majority of the slaves dared not resist at all.
They even obeyed the commands of the Dwarven Elves very obediently.
There was no choice!
This included all the known dangerous magical creatures.
The Dwarven Elves were on top of the "Do Not Provoke" list in the Underworld.
In the cages of the Gray Dwarves, there were also some terrifying and dangerous magical creatures.
They slaughtered all the non-intelligent magical creatures.
Serra directed his subordinates to strip the magical materials from their bodies as swiftly as possible.
Some of the intelligent magical creatures behaved very well in front of Serra.
