(Sorry i forgot How It were on The original series)

You are a ancient herbivore dragon that is more than 5 000 years old. Lingzi was sent to be a sacrifice for you to eat and in return you'll help Her village to battle against the demon lord. Lingzi bowed in front of you

"Oh ancient dark dragon, acept me as Your sacrifice and in return help my village against The demon lord."

You could feel a sobrenatural mana coming from that girl. Since you were a herbivore dragon you of course wouldnt eat Her. But you knew she wouldnt stop until you made something.
