In the fifth year of Wude, the early Tang Dynasty, Emperor Li Yuan is enjoying the fruits of his victory in the harem, surrounded by beautiful women. Li Jiancheng is busy securing his position as crown prince, Li Shimin is eyeing his brother's position, generals are fighting wars, civil officials are governing the state, merchants are trading with foreign merchants, and farmers are cultivating wasteland. Amidst all this, Li Xiu wakes up outside Chang'an city with a tombstone in his arms. Looking at the scene of the early Tang Dynasty, he sighs. Since everyone else is so busy, he decides not to bother them and live his own lazy life—eating and sleeping as he pleases.
