A modern soul transmigrates to the Great Ning dynasty, becoming Chen Chang'an, the disinherited legitimate son of the Ministry of Personnel's Vice Minister Chen, who is framed and persecuted by his family. His stepmother, Madam Zhao, sets a trap to accuse him of sexual misconduct, steals his marriage engagement, swallows all his late mother's dowry, and drives him out of the house. With nowhere left to turn, he encounters Princess Zhaoyue in disguise and Xiao Qingshuang, a chivalrous woman from a military family. When envoys from Yan challenge the dynasty to a contest of couplets, wagering the princess and cities on the outcome, the court officials are helpless. Down on his luck but brimming with talent, Chen Chang'an repeatedly presents ingenious couplets to avert national crises. He exchanges literary knowledge for martial arts training, establishes the Qingshuanglu enterprise to accumulate capital, masters the peerless Po Jun Art, exposes the Chen family's schemes, and confronts the powerful Grand Tutor's faction at court.
