Modern-day office worker Jiang Huan transmigrates into a book and becomes an insignificant concubine in the imperial harem. She originally intends to keep a low profile and coast through life, but unexpectedly discovers that she can hear the inner thoughts of Huo Lin, a ruthless tyrant who is actually a scheming glutton with the appetite of a starving ghost. To protect herself, Jiang Huan becomes the royal food provider, using her exceptional culinary skills to keep the emperor well-fed while rapidly rising through the ranks. As she navigates the schemes of the other imperial consorts, she joins forces with a fellow modern-day transmigrator to overcome one crisis after another. She also uses modern knowledge to help the emperor quell internal and external threats and launch ambitious infrastructure projects. Amid delicious food and political intrigue, the two gradually fall in love. In the end, the tyrant dismisses the entire imperial harem for her, and together they usher in a golden age of prosperity.
