Fang Li, a 22-year-old history graduate and food blogger, accidentally traveled to a replica of the Dayong Dynasty of the Tang Dynasty on a rainy night when she was double betrayed by her boyfriend and her best friend. She became an orphan named Ah Li who was sold into a wealthy family and suffered bullying. In a desperate situation, the "Baiwei Chang'an System" was accidentally activated, using food as a survival weapon. With modern cooking skills and historical knowledge, she started with multi-grain porridge from a ruined temple in Bianzhou, and knocked on the door of Chang'an with a flax cake that replicated the prosperous Tang Dynasty.
On the streets of the West Market, the "Fat Pear Chef" suddenly appeared - one person ate hot pot to warm up the cold night in the market, the improved spicy soup was hearty and spicy, and the rose cake for the girl's banquet was amazing in Chang'an. She helps orphans and connects farmers with empathy, and survives step by step amidst the oppression of Zuixianlou and the difficulties of tax collectors. She even unexpectedly meets the cold and forbearing censor Xiao Che. He secretly escorted her, and she melted the ice in his court with her fireworks, and the two-way love quietly grew among the pots and pans.
She performed in the palace to relieve Concubine Li's homesickness, turned decay into magic at a longevity banquet, and prepared for the Chang'an Food Festival to bring together flavors from all over the world. She broke class barriers with one meal and one dish, and was awarded the title of "Mrs. Baiwei". But no matter how high the palace wall is, it cannot be as warm as the fireworks in the city; and the glory added to it can never be as good as the love in the world. She resigned from the palace and returned to the city, expanding the "Baiwei Building", setting up a gourmet school, and writing "Dayong Food Chronicles", making food a link across regions.
From an orphan girl in Bianzhou to a food legend, from relying on the system to becoming self-confident, Fang Li healed others while also reconciling the pain of past betrayal. When the system completed its mission and went into hibernation, when Xiao Che took off his official robe for her, this journey through time with food as its blade and fireworks as its home ended in the morning light of Chang'an.
