After drowning in a public pool, a corporate slave awakens as Prince Marcus—brother to the most feared tyrant in history. Empress Livia rules with paranoid brutality, executing nobles on whims and crushing rebellions with her overwhelming Level 200 power. When the Praetorian Guard's coup fails and a massive purge begins, Marcus expects execution. Instead, his sister spares him for a childhood debt—by sending him to the frontlines as a slave-soldier. Armed with only Level 10 stats and memories of his past life, can a former salaryman survive barbaric warfare and maybe find a reason to live?
