Emperor System - Earth Rebirth?

Imagine our Earth, in a parallel reality, where humanity has died out, and tens of thousands of years have passed since then. Much has changed: geography, continents, flora and fauna, everything has become different. And instead of people, five other races live in this world, each of which is unique in its own way. And so, a simple guy from our reality gets into this parallel reality, unemployed, living his boring life on Earth... and what's more, he is given a special Emperor System, a strange, but quite interesting thing. And now he is forced to survive in this hostile and strange world, on this completely unfamiliar Earth...
