His aura itself seemed different.
The once dull black to brown hair had transformed into a deep and healthy shade of black that was so dark and glossy that it looked nearly blue when you stared for too long. When compared to Xuan Yang's glossy raven hair, the distinct coloring was more apparent.
Xuan Yang's hair was dark like an unending night, like the darkness could swallow you whole enticing one into its depths. This quality become more pronounced over the last few months. Xu Feng's nurturing was clearly beneficial to all three of the giants in his family.
For Erlang, the black was more illusory, where Xuan Yang gave one the feeling of overwhelming darkness, Erlang's locks were mystical and spell bindingly charming.
The luster was matched by Xuan Yang's hair only.
Other than the change in hair quality, Erlang's over tanned, cracked, and overworked skin had plumped up as if invigorated with collagen, becoming healthier and more nourished.
