Warhammer: The Emperor's Ravenbringer

the Terran calendar, the Unification War has come to an end, and the Primarchs have been scattered throughout the galaxy.

The Emperor is preparing to launch a great expedition to conquer the galaxy again and restore the former glory of mankind.

A time traveler incarnates as a raven, and has the ability to travel through the universe as long as he is bound to the protagonist of fate.

That day, the raven shouted to the big golden guy: "Let's go, let me take you to see the world."

So the gene engine of the Super God Universe, the Protoss technology of StarCraft, the Death Star technology of Star Wars, the Ether Phase Engine of the Stars, the Spark Source of the Transformers, the dimensional weapons of the Three-Body Universe and other cutting-edge technologies were all moved back to his own universe by the Emperor.

Many years later, the army of the human empire held high the double-headed eagle flag and conquered one universe after another.
