"Is this … is this the golden dragon's scale?"
Matthew nodded. He took the golden scale from the wooden box and gave it to Ruby. "Edgar brought it directly to me, and no one can forge the scales of the golden dragon."
That was because the scales also contained the blood of the golden dragon, so goldsmiths were able to distinguish between the golden dragon's scales and ordinary gold.
"After receiving these scales, I asked Edgar to observe the Tredo Kingdom for a while."
Ruby finally understood why she had never seen Edgar in the Imperial Capital, even though all the royal knights were assigned to guard the Imperial Capital.
"Then, how are things there?" asked Ruby curiously.
Matthew, "Edgar hasn't reported anything to me for the past three days, and that makes me feel uneasy."
