Su Wei, a modern nutritionist, unexpectedly travels back in time to Weigu Town, a place desperately short of ingredients. There, she discovers food scraps and discarded ingredients scattered everywhere. With the help of Uncle Wei, an old chef stubbornly devoted to preserving traditional culinary skills, Xiao Wei, an orphan, and the townspeople, she combines modern nutritional knowledge with traditional cooking techniques, determined to turn waste into delicious dishes. Along the way, they face numerous challenges, including criticism from wealthy families and ingredients ruined by torrential rain. Working together, they repair the communal kitchen and launch hands-on cooking classes. Their talents shine at the Feast of a Hundred Flavors, earning widespread recognition for their waste-to-delicacy creations. Together, they establish a complete food-waste recycling system, turning kitchen scraps into compost and repurposing old items. As traditional culinary skills find a new generation of apprentices, the timeless warmth of everyday life continues to fill Weigu Town.
