I, the shame of the dragon clan, am actually the most evil dragon?

Autobiography of a black dragon:
I was originally a happy dead house dragon, living a good life of sleeping and eating grass without fighting.
But such happy days are gone forever until a human girl named Lilith comes!

The self-report of the girl Lilith:
I am a sacrifice, determined from birth.My only honor is to sacrifice to some great being.But I never expected that a person like me would be eligible to be sacrificed to the great evil dragon Refendia!
The worries of the kings of Middle-earth:
The monster of the Age of Gods - the evil dragon has revived.Our rule is crumbling!
The troubles of the gods in the sky:
Something happened to Longlong, and things got bigger!We can't hide our baskets anymore!
A black dragon:
You are talking about evil dragons, what does it matter if I am a good-for-nothing black dragon?
What?I am the evil dragon? !
Hey, I made a mistake, I am obviously so weak!
Wait, girl, where does your power come from?
What?I gave it? !
