After dying, Chen Heng finds that he has transmigrated to an alternate reality: everything is the same, except the world is now a Wuxia world heavily influenced by martial arts! Not only this, he discovers that he has a Fantasy Simulator, from which he obtains rewards that make him incredibly powerful in his new reality as well. Martial arts, immortal cultivation, and overpowered abilities--all of this begins from a single simulation!
Having a modern military personnel as your citizens in a fantasy world will bring a new frontier to the progression of the story. Happily, there's a good deal of fun if you like things crashing violently into each other and out of warp-drive at regular intervals.
