God's Web Novel

Lee Hwan, the protagonist of a web novel, receives a once-in-a-lifetime offer from a god: help said god create his web novel in return for a wish. After agreeing to this deal, Hwan is thrown into a modern world filled with fantasy elements, new technology, and martial artists. All he needs to do is follow the plotline the author set out for him, except... there is no concrete plotline! With such a plot hole, can Hwan manage to come up with a story detailed and cool enough to appease its creator?
