Due to an accidental beta test experience, Alcat was transported into a game world and became the hidden boss—the Vampire Progenitor! He possesses a castle in the distant mountain range outside Aventon City and commands over 200 vampire progeny. In this arcane world, there are deities, giants, dragons, elves, demons, dwarves, humans, and dozens of other races, with vampires being one of them. Fortunately, he can travel back and forth between reality and the game world. However, the game will officially launch in a year, flooding it with numerous players. Three days in the game world equate to one day in reality. Not only does Alcat retain his human memories, but he also wields powerful racial abilities, giving him a three-year head start over other players. What challenges and adventures await him?
