He transmigrates to the Tang dynasty and chooses to play the fool.
Cheng Chumo, a history PhD from Peking University, transmigrates to the third year of Zhenguan and becomes the eldest son of Cheng Yaojin, Duke of Lu: a “dim-witted wastrel” notorious in Chang'an for damaging his brain in a fall from a horse.
Faced with a court rife with hidden dangers, he conceals his sharpness and uses “foolishness” as a shield. He pretends to be crazy and foolish to break off his engagement to a Wang family daughter, accidentally tames a spirited horse, offers “naive” advice that solves a drought in Guanzhong, and “clumsily” invents the wooden ox and gliding horse. The world laughs at him as a fool, unaware that behind that “foolish” facade lies a brilliant mind with insight into a thousand years of history.
