A while ago, there was an incident where the Five-colored Celestial Sparrow didn't manage to properly keep an eye on the nine-headed demon dragon, leading to it releasing some of its aura.
The whispers that Ye Tianfan hears are definitely caused by the aura of the nine-headed demon dragon.
The nine-headed demon dragon certainly wants to escape, but as a demon beast, it has no way to break the seal on its own, so it lures Ye Tianfan to be its pawn. A demon beast like the nine-headed demon dragon, once you help it break the seal, won't care about your fate; all its past promises are as good as nonsense and will never be fulfilled.
