Deception

"This is... a token. Keep it, and as long as you have this feather with you, I can find you at any time."

His voice carried an unnatural tone.

An Yao held the palm-sized golden feather in her hand, blinked, and was momentarily stunned. This feather was different from the ones she had seen shed by injured hawk-beasts before. It seemed larger, thicker in texture, and had more intricate and beautiful patterns. It gave off a somewhat obscure and sacred feeling.

An Yao suddenly remembered that Yuanyu had just plucked a feather from his chest. The feathers on the chest, especially those closest to the heart, were highly significant, as they represented the concentration of their beastly power. They possessed magical properties and were often used by hawk-beasts to craft magical tools.

Furthermore, the feathers from the chest had a tracking function, allowing the owner to locate them at any time.
