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!
I think the lead character in this novel is an unreliable narrator, and this adds another layer of complexity. If you’re a fan of both science fiction and fantasy, it is indeed a must-read.
