The blood test was a plot in the Legend of Zhen Huan, where the protagonist, Zhen Huan, dissolved her marriage with the emperor in order to prove her innocence. The following is the script for the blood test: (Scene: Yangxin Hall in the Imperial Palace) "Emperor, Zhen Huan, you're here." Zhen Huan: Hello, Your Majesty. Emperor: Why do you want to dissolve the marriage with me? Zhen Huan: Because I don't think there is true love between us. Emperor: True love? What do you mean? Zhen Huan: I mean there is no love between us. Emperor: Then what do you want to prove? Zhen Huan: I want to prove my innocence. Your innocence? What proof do you have that you are an innocent bird? Zhen Huan: I will use my own blood to prove it. (Zhen Huan took out a bird claw, inserted her finger into the bird claw and took out her own blood.) Zhen Huan: This is my blood. (The Emperor saw the blood in Zhen Huan's hand and placed it on the table.) Emperor: Is there any difference between your blood and this bird's blood? Zhen Huan: My blood is no different from this bird's blood. (The Emperor picked up the bird's claw and dripped it on Zhen Huan's arm.) Emperor: What color has your blood become? Zhen Huan: My blood turned red. (The Emperor saw the blood on Zhen Huan's arm and confirmed that it had indeed turned red.) Your blood is similar to this bird's blood, which means you are a bird. Zhen Huan:(surprised) That's impossible. (The Emperor concluded) Emperor: You are a bird, dissolve the marriage with me. Zhen Huan:(Feeling desperate) I understand. (The Emperor ordered Zhen Huan to be driven out of the palace)
