A Poor Man's Son-in-Law: He Picks Up the Daughter of a Duke's Mansion at the Start

A modern professor transmigrates into the body of a peasant scholar who, on his way to the imperial examination, saves a man by chance and ends up being clung to by the spoiled young lady of the Duke's mansion!
Everyone in the capital knew that Lu Qingyan was a "phoenix man" who climbed the social ladder by marrying into wealth, relying on women to rise to power. He smiled without saying a word, and was appointed by the emperor as the third-ranked scholar.
His doting wife was arrogant? He spoiled her so much that she became the epitome of power in the capital. His in-laws were difficult? He personally led the Duke's mansion to the pinnacle of power.
From a poor scholar to a top minister, he implemented reforms with one hand and flaunted his relationship with the other, rising steadily through the ranks while also dealing with all kinds of dissent.
"Trying to live off a woman? I live off the people's livelihood!"
