In the World's Apocalypse as the Dragon Cultivator

O-san, a pro player of an RTS apocalyptic and fantasy game called FERALR reminiscences about the game, and how full of life it was years ago, before being forgotten like all games do after a time. However, when he opens the game one last time for nostalgia's sake, he is met with strange pop-ups and messages alerting him about the end of the world as we know it, and the start of the game comes back to reality. With no other option, he is forced to join the FERALR game that turned out to be real, assuming the role of his Hero Unit: Hwang Sin. Now his duty is to survive the Apocalypse the apocalypse with the best of his abilities, and hope to beat the "game" FERALR as an Immortal Cultivator with a Dragon Bloodline.
