I Obtained the Demon King System but Traveled to the World of Cultivation

The bored joke gave Zhang Xiaodong the opportunity to travel to another world. Incarnated as a demon king, possessing the demon king system, the demon king's journey with the goal of destroying other worlds has just begun and has ended. "It is detected that the target world Agu Realm has been destroyed and the system's highest goal has been completed. All system permissions will be automatically enabled and all system rewards will be sent." Zhang Xiao didn't understand. If it ended as soon as it started, where would this ethereal world in front of him be? "The current world: the world of alien world. Automatically start the mission of conquering another world. " "Reward calculation completed: Obtain the only demon in the soul artifact set, obtain the source magic book, and obtain the four beauties of Agu Realm. You can return to Agu Realm to collect it."
