Transmigrate or Be Impaled

A man who spent over twenty years drifting through life without achieving anything, always dreaming of becoming an emperor. At last, he woke from his dream. Unable to sleep, he developed a split personality and was admitted to a psychiatric hospital. To his utter surprise, his illness made him an internet celebrity, turning his life around. But his good fortune didn't last long: the hospital turned out to be a transmigration base. He and his fellow patients transmigrated ten thousand years into the future.
