Roan then repeated what he said.
'His Dantian is using Yin Energy alone to cultivate.'
[Oh! Now, that's what I call as rare as phoenix feathers and qilin horns.]
Rean and Roan became puzzled.
'It seems like you know something.'
[Yep. In fact, it's quite simple. It also explains why he has such a feminine appearance even though he's a guy. This guy has a Pure Yin Body.]
'Pure Yin Body?'
[Yep. Do you remember what the Varen Tribe Leader, Jury, said? He thought that you two had a different constitution because of your Light and Dark Element affinities. Well, he isn't wrong since your bodies are perfectly compatible with Yin and Yang Energies.]
She then continued.
[This guy has a similar thing. His body is almost as perfectly compatible with Yin Energy as you two are with Yin and Yang. Of course, he's still a little bit lacking since he doesn't have the support of the Soul Gem System like you two have.]
