You Asked for an Invincible Hero, So Why Has the Desolate Heaven Emperor Appeared in the Modern World?

In a parallel world, Lu Yuan transmigrates into a story-writing contest. Faced with the prompt chosen by the judges: [Invincible] Lu Yuan writes: [One Sword to Sever the Eternal Ages] Just as Lu Yuan finishes writing about a young man leaving the Great Wilderness, ascending to the Ninth Heaven, and sweeping aside Di Jiang, ruins are discovered somewhere in the world. As the ruins are excavated and more and more bones of rare beasts containing terrifying energy come to light, people are horrified to discover that it all matches Lu Yuan’s descriptions in [The Desolate Heaven Emperor] exactly! The whole world is in an uproar! “Holy crap! The stuff in the novel is real!” “Immortal Emperor Lu Yuan reborn? He once severed the eternal ages alongside the Desolate Heaven Emperor? And fought King Chu Yan for the Nine Tribulations Sword?” “Battle qi turns into a horse, the Olden True God...” “So all of this is real?” Lu Yuan: How am I supposed to keep writing now?!
