Little People from Ancient Times

A social animal accidentally traveled across the prehistoric human race. He thought he could dominate the world through novels about the prehistoric times, but found that all this was just empty talk. Every living being has its own difficulties, and even a saint cannot live without these living beings. When everything comes to an end and all living beings are reincarnated again, where should the protagonist go? What exactly is a saint? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
