Song Mingyuan, the twelve-year-old illegitimate son of the Marquis of Dingxi, is framed, wrongfully accused, and humiliated. When he opens his eyes again, he possesses the soul of a modern-day PhD. Facing repeated schemes by his stepmother and his furious father's accusations, he voluntarily gives up his claim to legitimacy. Using his intelligence, he exposes conspiracies, sees through poison plots, and forces his stepmother to lose her influence, successfully securing his place in the marquis's household. Unwilling to accept this, his stepmother sends him to the clan school, where she deliberately suppresses and humiliates him. Refusing to be manipulated any longer, Song Mingyuan resolutely drops out and sets his sights on the imperial examinations. As the true face of his powerful maternal uncle, Chang Gaoyang, a formidable court official, gradually emerges, Song Mingyuan finally awakens to reality. Only by taking the imperial examinations, entering officialdom, and establishing himself at court can he break free from the constraints of the powerful aristocratic families and protect those around him.
