Faced with White Mitchell's query, Lucy frowned, promptly voicing her answer with some uncertainty: "If I am not mistaken, this Red Fire Azure Bird has likely already perished.
As to how it perished, and for how long, I assume that is something only it can answer.
However, even though it has perished, the power of spiritual beasts like the Red Fire Azure Bird far exceeds our imagination.
Even if merely a single beast core remains, given a chance, they have the potential to resurrect.
But don't worry, reviving such a powerful spiritual beast is an incredibly monumental task. Merely by its own efforts, it probably cannot accomplish it.

That is to say, its current power is not particularly strong so, for now, we have nothing to worry about.
Moreover, looking at its current condition, it likely won't hold on much longer.
