The dragon constantly roared and struck the cage. It was motivated purely by its desire for freedom.
"It's probably hungry..." Hobrick walked to the wall and tugged at a rope.
The top of the cage immediately opened up, and a pile of items dropped down.
They were gold bars!
The dragon finally calmed down upon spotting the gold bars.
It extended its claws, grabbed the gold bars, and stuffed them into its mouth!
"It eats gold? This thing is too difficult to raise!" It was then that Locke recalled the delivery birds transporting gold bars to the academy.
'Could it be?'
"Its appetite is very large, and it'll only grow bigger as time goes by. Traditional banks don't possess enough gold to feed it, and in order to keep this matter confidential, I'm forced to obtain these gold bars from the black market..."
Locke looked at the dragon that was munching on gold.
He finally understood the old man's greedy and stingy nature!
