Lin Xiaoxia, who transmigrated into the body of a little Tang Dynasty princess, is bound to the Prosperous Age Live-Streaming System. She had planned to coast through the imperial harem by telling jokes and making modern pop-culture references, but is forced to team up with an emperor known as the “food-loving boy emperor.” Together, they use Werewolf to catch corrupt officials, KPIs to evaluate the court, and stand-up comedy to handle diplomacy. Just as her “comedy-driven reforms” begin to take off, the System warns her that there are other transmigrators in this timeline, and that her livestream is being treated by an unknown advanced civilization as the ultimate testing ground for “human potential for happiness.”
