Warhammer: The Empire of Man is Also a Fallen Empire

Zhou Yan, a workshop technician, transmigrated into a clone of the Third Legion's Primarch, Vorgrim. "Damn it, Vorgrim, you've betrayed the working class!" "The Imperium is a corrupt empire, and the new humans are still humans... who's in favor, who's opposed!" "Some guy named Caul created a Legion of Primarch Space Marines for Guilliman... Byr, what do you think?" "Our overall strategy is to defend the Imperium's holy frontier, develop into the Imperium's dark side... sweep away the defeated Tyranid tentacles, and avoid the Necropolis of the Space Necropolis before we grow stronger... and most importantly, gather 18 Tyranid War Maidens!" After the Great Rift that tore the galaxy open, Zhou Yan led his newly formed legion to develop and grow, and the second human regime (warning: not the second Imperium) rose from the Galactic Far East!
