Xia Yi, derived from the way of heaven, is a soul who travels through various small worlds, specializing in helping those who are hurt, treated unfairly, and oppressed, but are powerless.
She came to their world to help them punish the evildoers, let them receive the punishment they deserve, and fulfill their unfinished wishes during their lifetimes.
When everything was over, they gave their soul power to Xia Yi, allowing her to gain the ability to open space-time rifts to help more people.
Purpose: Punish evil and promote good
