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!

At the end of the 42nd millennium, the Empire will be destroyed!

The fate of the Primarchs is uncertain, and even the Emperor will ascend to heaven.

In the name of the last Luna Wolf Loken, the Grey Knights established a new Brotherhood.

The Book of Omnipotence appears, the Void Dragon awakens, and the Ark of Bad Omen sets sail...
