The exchange room was a humongous room or, perhaps, a hall, enough to accommodate the massive size of immortal beasts. There, Davis was seated on a throne, appearing to be a speck of dust in the vast space.
Davis couldn't help but think that it was very professional of the Azure Radiance Slave Traders to treat their patron like a master who was about to purchase their slaves.
Moreover, he found out that the material that this throne was made out of was at the Immortal Grade, perhaps at Level One Immortal Stage, and since the throne seemed new with no amount of detectable remnant aura on them, he figured out that the Azure Radiance Slave Traders accommodated their patrons with new thrones that were one level higher than them every time a transaction took place.
