Su Qian, a top cardiothoracic surgeon, traveled through time and became a criminal concubine of Great Xia. She was trapped in a sky prison as soon as she woke up and will be buried with her to death tomorrow. At a critical moment, she discovered that the dying emperor Xiao Yi actually had acute airway obstruction, and took the risk to save him with surgery in exchange for a glimmer of life.
Deep in the palace, she discovered the chronic poisoning conspiracy of the Queen and the Regent, and relied on modern medical skills to detoxify Xiao Yi, but she attracted the paranoid possession of this sickly tyrant. Faced with strife in the harem and plotting in the court, Su Qian used her scalpel as a blade and resourcefulness as a shield to deal with Xiao Yi's fiery and dangerous control while dealing with the ambitious regent.
From a guilty concubine in the cold palace to the emperor's only favorite, she has to move step by step amidst the light of swords and shadows. Not only must she protect her own safety, but she must also join forces with Xiao Yi to crush the conspiracy to usurp power and control the destiny of the dynasty.
