Fusion/Fission

Living a rather disappointing existence on Earth, James is given a chance to live his life in a fantasy world filled with cultivation, immortals and a chance to be transcend to a higher plane of being. Transported by some God, Demon thing (?), James is gifted with the poorly defined power to be able to separate and combine things at will using his hands. His only goal is to create some karma with this new plane of being, separate ties with the old one, and try not to die and face eternal death. Simple, right?
