A modern medical doctor transmigrates into another world and becomes a princess consort in a marriage decreed by imperial edict.
Her husband is the Prince of War who once guarded the northwest, but now suffers from a leg injury and is targeted and oppressed by the Empress Dowager and the First Prince, caught in the struggle for the throne.
With peerless medical skills, silver needles, and miraculous remedies, she gradually cures his old injury.
The prince, who once lay low with his disability, regains his former edge. Standing side by side, they purge treacherous officials from the court, protect the young emperor, and remain together for a lifetime amid political intrigue.
