Half Xians could use the Xian spirits to find new bodies. This was the profoundness of the Xian Path.
If lucky, and their soul was not destroyed along with their body, that Half Xian would be able to be reborn over and over again. He or she would just have to start a new cultivation in a new body.
But that wasn't a problem that the Half Xians had to care much about. Because as long as they had enough resources, the Half Xians' cultivation would be very fast and return to its former glory.
This was such luck that Merlin had visited this land. Because this place would strengthen his original spirit or Pure Spirit. It was the preparation for him to receive lightning from the Heavenly Stage in the Soul Removal.
Merlin saw everything from the inside; he watched the kid's every action.
Once he was able to become a Half Xian; of course, the Merlin inside would have a chance to be reborn.
But right now, the first thing he had to do was to increase the strength of his original spirit.
