Their conversation from before continues...
Bai Qiyin asked, "How about your veil, Gege? What's its use?"
"It's to purify the qi in this realm. The Qi in this place is too thin and sparse. It wasn't even pure that it suffocates me without this veil. It would take a while before my vessel stabilized itself. At least a month more or two before I can stop wearing this veil," answered Hei Anjing.
Upon observing Hei Anjing all this time, Yun Huaxia noticed the slight black circle around his eyes. It wasn't that noticeable but... If one observes him closely one would notice how evident the light blackening under his eyes compared to his white and flawless face.
Sect Master Yun asked, "Are you... Having a hard time sleeping?"
"A bit..." answered Hei Anjing honestly.
