After being killed by a poisoned needle, a modern-day forensic doctor transmigrates into the body of a concubine-born daughter in an ancient chancellor’s household, forced to marry in someone else’s place. On her wedding night, she discovers that she and the God of War, the Ghost King, have been poisoned with the same toxin. After they are forced to sleep together, they become bound as “accomplices.” Together, they investigate the poison and solve cases, tracing the conspiracy from a mole in the prince’s manor to the empress dowager in the palace, and the source of the poison in the Southern Frontier to the enemy who killed her mother twenty years ago. In the end, they overthrow the empress dowager, destroy the Shadow Organization, have a child, open a clinic to save lives, and grow old together.
