Lin Su has been involved all her life, and her ultimate goal is to become a palace chef and revive the glory of her lineage. When she finally held the golden appointment letter and stood in the position of the top manager of the imperial kitchen, she felt that she had no regrets in her life. She even imagined her future retirement life: studying new dishes, teaching apprentices, saving enough money, and leaving the palace to open the first restaurant in the capital! Perfect! However, on the first day after taking office, at a state banquet prepared for envoys from neighboring countries, the head of the envoy suddenly foamed at the mouth and fell to the ground. Lin Suwei: "..." I'm just a cook. I really just want to cook quietly! Shen Du, the commander of the Forbidden Army, is known as the "Walking King of Hell" and is famous both in court and abroad for his sharp swordsmanship and iron heart. When he walked into the imperial dining room with a knife, everyone was so scared that they fell into silence. He picked up a plate of leftover "Splendid Eight Treasure Duck" and asked expressionlessly: "Chef Lin, besides duck, glutinous rice, ham... What else is there in this dish?" Lin Suwei sniffed it calmly and answered professionally and rigorously: "There is a strange poison from the Western Regions called 'Half Day's Leisure'. It is colorless and odorless, but when combined with a certain oil in duck meat, it will accelerate the onset of toxicity. The person who poisoned it is not only a master of poisoning, but also a top gourmet." Shen Du's falcon-like eyes showed surprise for the first time. From then on, Lin Suwei's career plan completely went astray. Today, we used the origin of food ingredients to deduce the enemy's food route. Tomorrow, the style of the enemy's spies will be identified from the knife skills of a dish. Recreate a lost famous dish the day after tomorrow, just to get some secrets from a certain old gourmet prince.
