Reborn in a Stone Age Magical Universe

at 109 years old dying wasnt that much of a surprise for world war 2 veteran Henry.



The death reaper he meets afterwards sends him through a portal to another world. A world with magic. With power over the fundamental forces of the universe.



the problem Is.. that his world is still a Stone Age society. Magic helps their lives, but not much, as magic helps them survive against fierce monsters and they don’t have any leisure to innovate.



Will Henry, now Kai in his new life be able to create an advanced society? or will he lose everything, and be reincarnated again.
