Does your low fertility have anything to do with my floating city?
Roland looked at them in confusion.
Realizing his confusion, Minko stroked his beard and explained, "Every dragon species needs something special to reproduce. For example, the golden dragons need to absorb a certain amount of Ebony Stone, and the bronze dragons have to eat mud regularly. For the silver dragons to procreate, our females must have a special element that can only be found in the shells of the worms in the Astral Plane."
Special element? Roland realized something.
But he still had questions. "Then why don't you hunt the worms in the Astral Plane?"
The elder dragons smiled bitterly, and Minko continued. "The Astral Plane is too high for us to fly to, even though we have anti-gravity spells."
"Then how did you procreate in the past?" asked Roland curiously.
