However, looking at it now, although the Heavensoul Sparrow is terrifying, it likely cannot enter this array for now, and there appears to be some powerful restriction on it.
That's why it seeks the key for its release.
Originally, Lin Xuan had no way to deal with such a formidable Heavensoul Sparrow, let alone obtain the Black Flame from it.
But now, it seems there's a possibility.
Because as long as they can find the Key to the Celestial Chain, with the help of the Dark Red Divine Dragon, they might have a slight chance.
Lin Xuan does not intend to kill the Heavensoul Sparrow, as he knows that even if the key is found, killing it would be impossible.
His target is merely the Black Flame on the Heavensoul Sparrow and the Essence Blood within its body.
Both of these are things that he and the Dark Red Divine Dragon desire.
So now, it appears they must find the Key to the Celestial Chain before anyone else.
