A man from a world ruled by a host of evil gods became a godslayer. Just as he slew the last evil god, the dying deity struck back and killed him. He was then reborn in a world called the Honkai World, with a new name: Gong Bingye.
(This book continues the story of the one about being forced to become a sword cultivator. Here's a little spoiler for that book: the protagonist's father, Gong Bingye, later gives all his divine power to his son, Gong Bingfan, to save him, and dies. This book is also called "About How I, a Godslayer, Turned Out to Be a God.")
