Su Wan, who was frustrated in the modern workplace, accidentally time-traveled to the prosperous Tang Dynasty, reduced to a bullied, failed palace maiden candidate. Framed and humiliated at the start, she broke through desperate situations step by step with her modern knowledge and calm mind, saving people to prove her innocence and rebuking the wicked to establish her sharpness. After entering the palace, Su Wan repeatedly shattered palace poisons, plots, and court malpractice, assisting the emperor with unique practical insights, and resolving the crises of the struggle for the heir and palace rebellion. Indifferent to power and wealth yet harboring goodwill, she disciplined palace rules internally and benefited the common people externally, neutralizing the calculations of the Pei faction of powerful ministers and palace consorts time and again, rising step by step from a humble palace maid to ultimately become the beloved noble consort adored by the emperor, the court, and the people.
