Jiang Huan transmigrates into the body of a minor cannon fodder character in the novel Tyrant Dynasty three months ago. The original host, a low-ranking concubine from a family of seventh-grade officials, died from a fever induced by a public slap from a senior consort. Jiang Huan’s only goal is survival; she lacks political ambition or special talents and wishes to remain invisible in the dangerous imperial harem. The Emperor, Huo Lin, is known as a tyrant who seized the throne by murdering his elder brother. He is cold, unpredictable, and has not visited the rear palace in three years, leaving the consorts in a state of bored rivalry.
During the Mid-Autumn Palace Banquet, Jiang Huan is targeted by Consort Yu, the senior consort of her palace, who publicly humiliates her. Forced to present herself before the Emperor, Jiang Huan lacks the artistic talents of the other consorts. Instead, she offers Huo Lin a bowl of fermented rice sweet soup she prepared herself. Unbeknownst to her, Jiang Huan can hear Huo Lin’s inner thoughts. She discovers that the Emperor is perpetually hungry, suffering from cold, bland meals provided by the Imperial Kitchen, and is deeply frustrated by the rigid court protocols that prevent him from eating warm food. His inner monologue reveals a man who is starving, irritable, and resentful of his ministers and eunuchs, despite his outward demeanor of icy authority.
Huo Lin is pleasantly surprised by the taste of the soup and invites Jiang Huan to sit beside him, shocking the other consorts who have been vying for his attention with elaborate performances. Later, when Huo Lin expresses a craving for crab but lacks anyone to peel them for him in public, Jiang Huan silently peels several crabs and presents them to him. Her act of service, driven by sympathy for his hunger rather than a desire for favor, earns her his notice. However, this attention draws the wrath of Consort Yu and Imperial Concubine Jia, who view Jiang Huan as a threat. Consort Yu punishes Jiang Huan by forcing her to kneel overnight and later slaps her after Jiang Huan is promoted to Changzai.
Despite being placed under house arrest in Jin Hua Palace, Jiang Huan continues to use her culinary skills to survive. She barters with a eunuch from the Imperial Kitchen, using her cooking to secure ingredients, and prepares dishes like iron pot braised goose for herself. Meanwhile, Consort Yu attempts to replicate Jiang Huan’s success by preparing food for the Emperor, but her lack of skill and heavy use of perfume result in Huo Lin’s disgust. He orders her to be dragged out of the Hall of Mental Cultivation, further isolating her faction.
Huo Lin’s hunger remains a constant source of internal turmoil. He frequently complains about the cold congee and vegetables served to him, longing for the warm, flavorful food Jiang Huan provides. Jiang Huan, aware of his preferences through his inner thoughts, continues to smuggle food to him when possible, such as apricot blossom cakes hidden during the morning court session. Her actions earn her a promotion and the title Zhuang, making her the first concubine to serve the Emperor in three years. However, her low status and lack of family backing make her a target for the other consorts, who spread rumors and scheme against her. Jiang Huan navigates these dangers by maintaining a humble exterior while strategically using her culinary gifts to secure a fragile position in the harem, all while trying to avoid the lethal intrigues that define life in the palace.
