As spiritual energy resurges and the apocalypse descends, Lin Ye, who possesses no supernatural abilities, is deemed to have "no survival value" by the Dawn Base and expelled from the city to fend for himself. At the brink of death, he activates the Spirit Chef Sign-In System and obtains the Origin-Purifying Jade Pot. The highly poisonous demonic beasts that everyone fears become top-grade spiritual delicacies in his hands. He turns poisonous umbrella mushrooms into refreshing jelly that opens the meridians, fries bone-corroding centipedes into crispy strips that boost combat power, and simmers the Ink Jade Scorpion Emperor into a delicious soup that helps powerful cultivators break through their realms. Starting with a tiny shop at the foot of the city wall, he humiliates orthodox spirit chefs, wins the championship of the Spirit Chef Competition, and unlocks an ancient culinary inheritance. While everyone else avoids demonic beasts to survive, Lin Ye chases after them with his cooking pot, creating a legendary wasteland culinary sage with nothing but one pot.
