After only a few moments of thought, Alex came to the understanding that there was indeed a place in the Eastern Continent where one could find many treasures that would immediately make one's standing in the Immortal realm higher than it would be on arrival.
A place where the Dragon Emperor was likely to find Immortal artifacts, talismans, and treasures. A place that was so easily accessible, but couldn't be opened because the Dragon Emperor didn't have talent in Space and needed the sword to use.
The Azure Dragon's Soul Space.
Alex feared this was it. He could imagine the Dragon Emperor's greed and could see that with the Azure Dragon's corpse so close how desperately he would want the sword.
When someone became an Immortal, they opened a Soul Space in their body. Once opened, that space would remain there forever unless destroyed. That was what he had been told in the Central Continent by Senior Yang.
