The Heirloom Recipe

Biyuan, the master of the manor, is busy preparing a feast for the prince. He tells the doctor and the steward that the prince's body has been attacked by the "polar effects" of the two poisons within him. The steward asks Biyuan what is wrong, and Biyuan tells him that the old slave, who has been watching the prince grow, has never suffered such an injury before. He also tells the steward to take a look at the potion on the bottle, which is a "potent tonic" from the royal palace. Biyuan is shocked to learn that the brothers are really the same, but she assures him that it is because she has given him a shock.
