After modern food blogger Song Wan time-travels, her family is wrongfully convicted and exiled, and she enters the palace as a servant. Binding with the Peaceful and Prosperous Era System, she sweeps through the harem with modern delicacies such as river snail rice noodles, fatty intestine mixed noodles, and hot pot. A host of imperial concubines and princes are captivated by the food. The crown prince of the Liao State loses a culinary duel to Song Wan and trades hot pot for border peace. The emperor places her under house arrest to monopolize the food, and the crown prince seizes the opportunity to launch a rebellion. Using a secret passage, Song Wan helps the crown prince, who is also a time-traveler, ascend the throne and clears her family's name. The new emperor wants to make her empress, and the two reach an agreement: Song Wan is bestowed the title 'Food God' to govern the empire's cuisine. When the quest progress is stuck at ninety-nine percent, the system sends news that her missing younger brother, Song Ze, is still in Lingnan.
