The lines of Legend of Zhen Huan's blood test were as follows: Zhen Huan: I'd like to thank you on my behalf with this blood. Emperor: Why do you want to use this method to prove your parent-child relationship? Zhen Huan: Because I believe that kinship is irreplaceable. If parent-child relationship can be proved by a drop of blood, then what is there to trust in those who betray kinship for benefits? Your Majesty, do you mean to use this method to maintain the purity of the royal family? Zhen Huan: Yes, I think the royal family should maintain its purity and anything that might destroy this purity should be avoided. Emperor: But you will damage the image of the royal family. Zhen Huan: I understand, but this is the only way to keep the royal family alive. Your Majesty: You mean the image of the royal family is not important, what is important is your kinship and loyalty? Zhen Huan: Yes, I think kinship and loyalty are the most important things for a person, and any pursuit of them can make me give up my loyalty to the royal family.
