Datang: Apocalypse of Modernization

During the Zhenguan period, why were there square dances accompanied by pipa every night in shops in Chang'an of the Tang Dynasty? Why did the green forest warriors in the tavern fight over the outcome of the Three Kingdoms Game? Why do the princes and princesses in Daxing Palace eagerly wait for the Weekly Shonen Jump magazine at the beginning of every month? Why are the carriages running in the Tang Dynasty labeled "Didi Carriage"? I, Li Yi, His Highness the Ninth Prince of the Tang Dynasty, just want to invent and create, advance science and technology, draw cartoons, make money, and defeat Turks, Goguryeo, and Japan... How come I am designated as the crown prince? Don't panic, let me read a poem first. This novel and its characters are purely fictitious.
