After Lin Xuan's boss takes credit for his achievements and cuts his salary, he angrily quits his job. Just as his seriously ill father urgently needs money for surgery, Lin Xuan unexpectedly unlocks a system. Its first mission requires him to sell 300 portions of extra-spicy grilled chicken wings outside a proctology hospital within three days. Thanks to his outstanding cooking skills, his little food stall quickly becomes a sensation. He then travels from place to place, setting up stalls and completing one entertaining mission after another. He turns down huge investment offers and establishes special dining requirements, with a simple bowl of egg fried rice outperforming even a high-end seafood buffet. Once a frustrated office worker, Lin Xuan rises to become the legendary culinary master everyone in the city adores.
