Ning walked out of the city and made his way toward the forest. He then settled down on the thicker part of it and brought out his Aether from the bag.
Fighting against the Midnight Phoenix had depleted his Aether to such an extent, that it had finally made him aware of the fact that even between the different energies, there was a sort of hierarchy.

If even a weaker Immortal bird with no intelligence was enough to give him trouble, Ning could only imagine what an actual immortal with all of their mental faculties could do.
