a true blood line

It depends. Sometimes stories labeled as such are based on real events but with some fictional elements added for entertainment purposes.

Blood test is a classic line in Legend of Zhen Huan. It comes from episode 78. The following is the general content of the line: Zhen Huan: Your Highness, you're right. This fetus isn't ours. We have to find a way to kill it. Emperor: Zhen Huan, why do you say that? This fetus belongs to both of us. What evidence do you have to prove that it's not ours? Zhen Huan: I have evidence, Your Highness. This fetus has our blood. You know the principle of blood test. Emperor: Blood test is not a scientific way of proof. Why do you want to take the risk? Zhen Huan: For our family, for our future. If we let this fetus live, then we will become the second pure Yuan Empress. This is something we can't accept. Emperor: You are right, Zhen Huan. We won't let you become the second pure Yuan Empress. We're going to let this fetus die. We're going to lock you up in the cold palace. Zhen Huan: Your Highness, can you calm down a little? We can't lose our freedom and dignity because of a fetus. The Emperor: You are threatening me. I won't let you go this far. I'll give you a satisfactory answer. Zhen Huan: I don't need answers, I just need freedom. I will fight until I get the respect I deserve. That was the general content of the blood test.

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.

It's not a true story. It's a fictional film that's inspired by certain themes and situations but not based on actual events.

Partly. While it has elements drawn from real situations, it also takes some creative liberties for dramatic effect.

No, it's not a true story. It's a fictional film inspired by various themes and ideas.

To some extent. While it may draw from real elements, it also takes creative liberties to make the story more engaging and cinematic.

I don't think it is. Usually, such works are fictional creations, not based on real events.

I'm not sure. It depends on various factors like the source and the author's intention. Sometimes stories are inspired by real events but have fictional elements added.

Hard to say. Sometimes movies claim to be based on true stories but take a lot of creative liberties. So, for 'On the Line,' it's tough to know for sure without more background info.
