In this story I decide to explore parallel world's. Originally I was going to stick to a cycle of reincarnation on Earth in the modern era. But decided to add five types of parallel worlds.
1. Origin World: This is modern day Earth. This is Earth as we know it in 2019.
2. Magic Worlds: This is an Earth where magic was developed and advanced instead of science.
3. Science Worlds: This is an Earth where the sciences boomed and far exceeds our current knowledge.
4. Cultivation Worlds (magic and martial arts): This is an Earth where cultivation was developed.
5. Magic and Science Worlds: This is an Earth where magic and science developed hand in hand.
6. Science and Cultivation Worlds: This is an Earth where science and cultivation developed hand in hand.
Though their is only one Origin World their are many other worlds that follow one of the 5 listed world types.
