Waking up from a nap, Li Xuan became the universally reviled "ravine crown prince". He originally wanted to conceal his identity and save his little life, but was pushed onto the imperial throne by a group of unreliable "founding meritorious officials", and by a twist of fate gained an empress. Seeing government soldiers closing in step by step, the makeshift troupe of a few hundred people tossed and turned until it looked more and more like a real dynasty. Since there was no escape, Li Xuan simply grasped military power, drilled troops, and expanded territory, going from survival to contending for the world. But when this absurd "Great Tang" truly shook the world, could he still guard his original self who only wanted to survive?
