Wang Ling, a modern graduate student of history, unexpectedly travels back to the Great Zhou dynasty and becomes the burly second young master of the Wang family. Turning over a new leaf from his formerly unruly ways, he devotes himself to studying at the Imperial Academy and uses his extraordinary courage and intelligence to resolve one crisis after another. His elder brother, Wang Gui, suffers from a chronic illness but possesses profound knowledge and unwavering scholarly integrity. The family supports one another, upholds righteousness, and faces the factional struggles at court without abusing their strength to bully the weak. Wang Ling tempers his character and resolves to earn an official title through the imperial examinations, protect his family, and defend justice in the world. Through these trials, the young man ultimately matures and transforms.
