Every world had its own Child of Fortune. A Child of Fortune was a prodigy that was loved and favored by the heavens from the moment they were born. Even when they were walking on the streets, they may even trip over some kind of Spiritual Treasure.
Powerful enemies who were chasing after them may have suddenly died of a heart attack!
If they were to fall from a cliff, they would fall onto a branch and stumble upon an unrivaled Legacy!
When they were casually selling a ring on the side of the road, they may get visited by an old man that was actually a hidden ace!
Each of these people was existences that had the heavens' special care, and the birth of every Child of Fortune signified a state of the world that was everything but ordinary.
Only the Child of Fortune born of each era could continuously expand the upper limits of the world and bring about an elevation for the world in the future.
