Stranded in a mysterious realm shrouded in fog, Li Mu acquires the ultimate weapon: the Spark Battleship Phoenix.

In the Spark World, humanity survives within giant, mobile Spark Cities—steampunk fortresses that crawl across the land, colossal citadels built on the backs of behemoths, and silent metropolises that drift through the sky and sea. These cities are humanity's shield.

For a spear, they wield Spark Battleships, vessels that tear through dimensions to conquer parallel worlds for resources and power. But the Phoenix is different. It is the only ship capable of entering the "fantasy worlds"—the fictional universes from Li Mu's past life.

Now, the stories he once loved are his targets. With advanced technology as his weapon, he will unleash the might of the Phoenix upon worlds of magic, monsters, and mechs. The conquest of fiction has begun.

First Worlds: Harry Potter, Pacific Rim, Neon Genesis Evangelion... and many more.

Long Fei was an otaku who transmigrated into another world. In his original world, he was a dedicated fan of Gundam and a military science fiction enthusiast.

Following an accidental death, he was reincarnated in a different world. To his surprise, all the technology from the Gundam series he had watched and the various military sci-fi novels he had read during his lifetime was brought with him into this new reality.

The Gundams that Long Fei builds—how will he decide to use them? What kind of waves will he be able to create in this strange new world?
