Jiang Yetang cooks in an ancient house in Shenxiang, and every chopstick and spoon contains the secrets of the royal chef. The world only knows that her cooking skills are magical, but they don't know that what she cooks is not the dishes, but the royal secrets that have been buried for hundreds of years. Pei Luzhi, an orphan from the previous dynasty, took a blood oath to find the lost true biography of the royal meal. In order to get a glimpse of the delicacies, he quietly sneaked into her door. He watched her cooking like a dance and listened to her whispering ancient secrets, thinking it was a chance, but he didn't know that she had been waiting for him in the fire for thousands of years - that "ambergris amber soup" only needed to be tasted by him to restart the sleeping imperial veins.
