Modern office worker Yu Wei transmigrated into a century-old peach blossom spiritual mandarin fish, nearly becoming a sacrifice for the Huashen Assembly. In the desperate situation, the remnant soul of Mao Wendao, the descendant of the ancient Food God, appeared, turning the Maillard reaction and microbial fermentation into cultivation techniques, teaching two secret canons. Relying on the unique culinary cultivation technique derived from stinky mandarin fish, he battled Sichuan cuisine genius Tang Liao, Kaiseki style Kamiyagawa, and others, and twice fought against the fierce beast Taotie. Side by side with female chef Meng Shiyan, they ventured into the secret realm, uncovered sealed past events, and joined hands with the sect masters of the eight major cuisines to quell the catastrophe. After achieving success, Yu Wei rejected the sect's power and position, guarding Chinese fermented delicacies amidst the mortal fireworks and completing the transformation of the guardian of Middle-earth flavors.
