Sign in for a Million Years: Become the NPC Emperor at the Beginning

Sign in for a million years, be reborn as a young emperor of Xuanwu Kingdom, and have to defend the imperial city at the beginning! The promised sign-in system actually summoned a large number of online game players and even regarded themselves as NPCs! Well, that's fine. So, go give me a task and select ten beautiful players to dance in the palace, regardless of gender. If you dance well, I will reward you with a world-destroying demonic sword! Your Majesty... That is a divine weapon... What kind of broken artifact, go quickly, I can't even fill it in the emperor's space...
