Modern cooking terms such as "molecular gastronomy", "Maillard reaction" and "Umami" confused and shocked ancient people; kitchen utensils such as spray guns, siphon pots and liquid nitrogen tanks were regarded as unheard-of "alchemy tools" or "god creations". This collision of ancient and modern cognitions has brought continuous freshness and interest.
**Su Chen (actor)**: A frustrated chef in a modern Michelin restaurant who was fired for pursuing innovation too much and traveled to the Song Dynasty. He has top-notch cooking skills and an arrogant and pragmatic personality. He is neither humble nor overbearing when facing "distinguished guests" (because he does not know that he is a distinguished guest). He has the ingenuity of a chef, but he will also be unceremoniously venomous towards diners who do not appreciate food. He is the center of all the fun and plot conflicts. After traveling to the Song Dynasty, he worked as a slave in Zhao Xin's house and showed his extraordinary cooking skills. He was eventually recruited as a son-in-law and inherited the Zhao family business. He had the opportunity to come into contact with Song Zhenzong, so he could provide new dishes for the palace, and then he was rescued and entered the court as an official.
