Xiao Jin, the former royal chef genius who was reborn on a snowy night, alarmed Jiangnan salt official Shen Zhao with a bowl of leftover soup. When the 'Ambergris Stewed Phoenix Marrow' that has been lost for hundreds of years reappears in the market, the orphan of the royal family, the manipulator of flavor poison, and the mute boy who hides the secret map appear one after another. What he restored was not just the dishes, but also the soul of the burned national weapon. The bloody jade key in Shen Zhao's hand pointed to the real mastermind behind the burning of the Imperial Diet Book - the real father of the emperor.
