In the vast continent, airships that cover the sky and the sun fly across the sky, and roaring steam trains connect every city. After Zhang Lang, an ignorant boy, got a strange little tree that was constantly evolving, he was kicked by the God of Destiny into the torrent of the times. In the battle between humans and demons, the boy's figure was looming...
Cthulhu's industrial civilization runs parallel to Eastern fantasy, and the fate of young Zhang Lang is intertwined with the human race.
