I'm not sure but I think it's because he activated it with some words or song at this moment, although I can't help thinking that he already had blood thick enough to begin with since some flames got into the ring. （￣へ￣）
He has dragonblood but the concentration is not that high that's why he needed to activate it with the other blood and the blueheart grass... as for the flames from the ring, it's just because there are artifacts that must be bounded by blood, and that's the case of the ring :)
Im around CH 50 and I'm kinda confused. From what I see Linley already has a high concentration of dragonblood in his body, why did him drinking dragon blood and eating the blueheart grass made that kind of transformation to his body?
