Even though Little Blackie had already advanced to the Elder Dragon level.
And possessed Legendary Tier combat power.
It still could not compare to Eagle Sauce, equipped with the [Mana Jet Augmentation], in terms of flight speed.
Moreover, Eagle Sauce had not been idle during this time. Its strength had steadily improved by small margins.
