Huo Hai, an ordinary modern-day loser, transmigrates into the body of a puppet emperor of the Great Li Dynasty and becomes bound to the "Dynasty-Fall System." As long as he brings about the downfall of Great Li, he can return to the modern world and receive a trillion-dollar reward. So he goes all out, burning imperial robes, forcibly conscripting women from noble families, staging beacon-fire deceptions to fool the feudal lords, and coming up with one outrageous way to sabotage himself after another. However, every foolish move he makes is interpreted by the powerful minister Qin Hui as profound imperial strategy. Through a series of hilarious misunderstandings, Huo Hai ends up consolidating the empire and defeating enemy nations. Sitting on the imperial throne, Huo Hai completely loses his mind: "I just want to destroy the dynasty! Why do you keep praising me as a wise ruler?!" And so begins a riotous comedy of one disastrous attempt at self-sabotage after another.
