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!
The author clearly has a cuck fetish and tries to justify this in the story because "that's how the world work". Awful novel, give this a skip and read one of the number of better stories out there.
