Su Wan, a modern history PhD, transmigrates into the neglected mistress of the Northern Town Marquis Mansion. She wakes up to a concubine framing her for "harming the young master". Using *Collected Cases of Injustice Rectified*, she proves the boy’s "strange illness" is food incompatibility, slapping the accusers in the face. She also uses arithmetic to expose the steward’s embezzlement, saving the mansion 100,000 taels. The cold Marquis Xiao Zhan initially wants to mock her but is gradually captivated by her intelligence—when she uses a sand table to solve the border army grain crisis, Xiao Zhan can’t help pinning her in his study: "I want to build my kingdom with you." Little does he know, Su Wan’s *Modern Management* book hides a note with his birth date—she’d memorized the "future emperor’s" life before transmigrating!
