Ultimate Experience

[Warning: grotesque violence, excessive gore, r*pe, morally questionable content, and a protagonist who means well] A man spent 100,000 years in endless battle within an immaterial realm to be reincarnated into a fantasy world. Within that time he became an animal who knew nothing but war. He had forgotten who he was before and even forgot how to speak, but he gained a skill from 100,000 years of war; he gained Ultimate Experience.
