If im not mistaken, when his master saved him (after he killed himself after being forced to shoot his father), his master painted some sort of spell on his face. And after that he hasn't opened his eyes and lived as a blind man. He wasnt born blind, he could see as a kid
Based on ch.108, ryeong is not actually blind but there's some kind of curse that doesn't let him open his eyes unless that someone he talks about frees him from it and that someone is the jaw, right?
In the earlier chs I thought he harmed his own eyes bc they were the reason of all the tragedies in his life or smth like this
